A Virus powered battery

MIT scientists have engineering the first viral assembly line workers

Engineers at MIT have figured out a way to deal with virus that is better than just killing them: they're putting them to work. The researchers have developed a new technique wherein a key component of a microscopic battery is assembled by viruses, allowing for the cheap and simple construction of very small power sources.

The research, first published in the journal The Proceedings of the National Academy of Sciences, builds on earlier work by the MIT group involving viruses. In the earlier experiments the scientists genetically engineered viruses to make a protein skin that attracts bits of metal. In the new experiment, the researchers put that skill to work by having the viruses build a specific part of a larger machine.

Batteries are composed of four key components, an anode and cathode that form the positive and negative poles, an electrolyte that transfers the electric charge between them, and a separator to keep the anode and cathode apart. In the MIT experiment, two polymer layers that would serve as the electrolyte and the separator were lain on top of a four micrometer wide post. The genetically engineered viruses were then encouraged to grow on top of those layers, where they would attract a metal, in this case cobalt oxide, which would serve as the anode. The researchers still haven’t engineered a virus to make the cathode, but that is clearly the next step.

The whole process is especially attractive because of its easy and low cost. The problem is application. Right now, there are no devices that require a battery one tenth the width of a human hair. However, in the future these small batteries could serve as the primary power source for a wide range of nanotechnology. Which is good, because in these days of green energy we wouldn’t want our nanotechnology running on coal or oil.

The $25,000 sports car question

Chismillionaire votes for the Acura NSX- low cost maintenance, proven 150,000 mile durability, great looks and an even better engine note at 7800rpm.



Given 25 grand to spend on a car that’s fun to drive, what would you buy? Would you take the safe road and get a new car such as a Mazda MX-5 Miata or a Volkswagen GTI, which come with the security of a warranty? Or are you a risk taker willing to go after something special that might be a decade old and have serious wear issues and plenty of miles, maybe a used Acura NSX?

It’s a dilemma that will be argued noisily forever, but we’re here to stick our collective necks out in hopes of providing some answers. We’ve gathered nine cars—two are new and seven are used—that can be purchased for about $25,000.

The cars were chosen by the staff for a lot of personal reasons, including performance, style, and relative practicality. Several are cars that we have long lusted after but most of us never could have afforded when they were new.

Used-car prices fluctuate all over the place, so we relied on the Kelley Blue Book 1993–2007 Used Car and Truck Guide—using the estimated prices for cars in good condition that are sold between private parties—as well as the used-car Web site AutoTrader.com.

We don’t own a used-car lot, so we had to borrow cars from owners. We asked the owners to meet us at GingerMan Raceway in South Haven, Michigan, for a free-for-all day of driving. We cycled through the cars, driving both on the racetrack and public roads around it. Since all of the used cars were in varied condition—the 1999 Mercedes E55 AMG we borrowed had almost 200,000 miles on it—we didn’t rate them by our ritual rules that govern comparison tests. In the pages that follow, we recount what the cars felt like and what items buyers should be wary of. We also rate the used cars in three categories—operating costs, curb appeal, and fun to drive.

So which one is the most fun? Which one would we buy? That depends on whom you ask.

For enthusiasts on a limited budget, a new VW GTI or Mazda MX-5 is tough to beat.

In addition to being wonderfully entertaining, the five-door GTI featured here is a remarkably well-rounded car. Fold the rear seats, and it’s a pint-sized minivan. Jump on the interstate, and it tracks as straight as its German heritage suggests it should. Most importantly, it’s as fun to drive as it is practical, with an eager turbo engine, a good gearbox, and a frisky chassis. If you can only have one car, the GTI is close to perfect.

The MX-5 Miata, on the other hand, exists purely for the joy of driving. Sure, it has a reasonable trunk—and pricier models can be had with a folding hardtop—but at its core, the Miata is a driver’s car. It’s wonderfully balanced, with an engine that’s willing but not overpowering, a gearbox that’s one of the best in the business, and handling that makes running an errand an enjoyable experience. There are certainly faster cars, but few are as satisfying.

As a testament to just how far Honda pushed the envelope with its 1991 Acura NSX, compare it with the most sophisticated machinery of today. That first NSX’s 3.0-liter V-6 made 270 horsepower and revved gloriously to its 8000-rpm redline. Almost 18 years later, BMW’s direct-injection 3.0-liter (in the Euro-only 330i) makes 268 horsepower.

The NSX’s lightweight aluminum sheetmetal surrounds a fascinating 3000-pound wedge that still looks fresh today (if you don’t count the tiny 15- and 16-inch wheels). Combined with first-rate comfort and ergonomics, and a docile, aluminum-intensive unequal-length control-arm suspension, it’s easy to see how the NSX quickly won our hearts as well as a distinguished victory over a Porsche 911, a Corvette ZR-1, and a Ferrari 348ts in a 1990 comparison test.

Having purchased this Formula Red example new in December 1990, it’s safe to say Ken Sax (which he amusingly writes “keN SaX”) of Evanston, Illinois, is quite familiar with his 78,000-mile car as he’s exercised it to the tune of 13,000 on-track miles. The car has held up well, mostly needing replacement of such predictable items as worn brake pads (25 front sets, 16 rears thus far) and chewed-up tires, although his NSX suffered a rare catastrophic engine failure caused by a broken harmonic-balancer pulley that led to a jump of the timing belt. Sax replaced the engine with a $4500 used one, which was the cheapest fix.

We all were impressed at how solid and modern his NSX felt. Sure, there were a few squeaks and rattles, but it rides forgivingly, is quiet, and still feels structurally sound. Sax’s car does have some minor scuffs in the interior and noticeable wear on the seat bolsters, which is common.

The manual steering is just as alive as we remembered, its on-track poise is phenomenal, and the five-speed manual’s short, precise throws are still a benchmark. Sure, a 0-to-60-mph time of 5.2 seconds doesn’t qualify as blazing anymore, but the flexible engine absolutely wails above 6000 rpm. We nominate it as the best-sounding V-6 ever.

From 1991 until it was discontinued in 2005, the NSX’s price ballooned from $60,600 to $89,765, even though it evolved very little. A targa model was added for ’95; a 290-hp, 3.2-liter V-6 and a six-speed manual were new for ’97; and the NSX got a fixed-headlight face lift for 2002. The ’97-and-newer cars still fetch $40,000 to $50,000, while the ’91–94 models have held steady in the range of $25,000 to $35,000 for almost 10 years.

By exotic-car standards, NSX ownership is painless, but there are a number of known problem areas—a faulty transmission snap ring and fragile power-window regulators on ’91 and ’92 models, as well as a history of rapid tire wear. So do your homework first. Be especially wary of the service history, as many lower-mile examples haven’t kept up with recommended maintenance such as timing-belt replacement. Fortunately, www.nsxprime.com houses a strong and knowledgeable owners’ community and is bursting with information.

The NSX was truly an exotic turned everyday friendly. It’s no wonder owners of these inexpensive, high-mileage cars are so enthusiastic.

It’s hard to believe, but Horst Reinhardt’s E46-series BMW M3 has nearly 67,000 miles on its wrinkle-free body. Except for some road rash on the wheels and front bumper, and a bit of wear on the driver’s seat and a few of the interior panels, the car he bought in May 2003 looks new. You’d be lucky indeed to find an M3 that has been looked after as fastidiously as this 2003 example, but there are cars of this age and mileage out there for less than our $25,000 target price.

Reinhardt bought the car new, and its only major options were heated seats and a navigation system. There’s no sunroof, and the material covering the seats is cloth. Reinhardt runs VR Performance, a tuning business that specializes in these cars, so he fitted his M3 with Eibach springs that are about 10 percent stiffer than stock and added a CSL-like carbon-fiber rear valance, trunk panel, and front air-dam extensions.

Reinhardt has racked up about 10,000 track miles on his M3 but says the car is so sturdy that he has basically just changed brake pads and rotors. He adds: “The only real problem areas are rear subframes that can crack if stiffer springs are fitted for track work. Early cars had problems with their big-end bearings—but all of those engines were replaced by the factory.” Our local BMW dealer in Ann Arbor said that the rear coil springs also can crack.

If our test crew had voted, the M3 would have been the standout among this group of cars. While the newest M3 is a magnificent machine, the previous E46 model is just as practical and nearly as entertaining to drive, and its performance is more accessible to more people.

Performance is strong—back in the day, we recorded 0-to-60-mph times in the range of 4.5 to 4.8 seconds—and the inline six-cylinder engine is both willing and sonorous. On the track, it’s fast, immense fun, and beautifully balanced; on the street, it’s refined and easy to live with, thanks to a great driving position, a decent back seat, and a sensibly sized trunk. Plus, it’s new enough that it has a full array of safety features, with airbags and stability control heading the list.

The only catch is that parts for this car are expensive. A surf around cyberspace reveals that rear brake rotors retail for about $150 each, with fronts going for about $200. Replacement OEM catalytic converters are $1250 each. Reinhardt notes that there “are now lots of aftermarket bits available, from body panels to steering racks and brake rotors.”

We suggest looking for E46 M3s on used-car Web sites and trying the BMW Car Club of America (www.bmwcca.org). On the evidence of Reinhardt’s M3, you’ll be getting one hell of a car for a relatively modest outlay.

In the speed-per-dollar column, the Z06 dominates, just as it did when new. A 2002 model such as the one we rounded up here ran 0 to 60 mph in four seconds flat and hit 100 in less than 10 seconds. Mark Benson’s car felt every ounce as strong as the original.

“Spectacular,” one of our test crew wrote. “This car still feels tight and very strong.” We all marveled at how new this car felt—with just 21,000 miles, it was almost new. Still, we have found that if a car is going to develop a severe case of the rattles, it usually happens during the first 20 grand on the odometer. This car was simply shake-free. We also couldn’t find a blemish on it. The only problem—and this is an uncommon one—was a passenger-side window that wouldn’t go down.

All the things we salute in a Corvette were present. For starters, the 405-hp, 5.7-liter V-8 is impressively flexible. It supplies snappy throttle response just off idle yet still pulls like mad to 6500 rpm. The shifter in this example is particularly light and direct, better than we remembered. The chassis delivers a good ride and loads of grip and is so predictable that the car can be driven in hooligan mode—the tail sliding out—or smooth and tidy. Finally, the Z06 has great brakes and a firm pedal.

On the other hand, all the things we’ve never liked about the Corvette also were present. The flimsy seats still feel woefully inadequate, and the plain, black plastic dash reminded us how far the latest Corvette interior has come. Those are minor quibbles, though, and shouldn’t detract from a relatively easy ownership experience.

“In terms of maintenance and reliability, Z06s aren’t much different than a Malibu,” says Jason Haines of the Corvette tuning house Lingenfelter Performance Engineering. The engines are bulletproof, and most of the running gear is robust. As always, potential owners need to watch out for excessive abuse. If the transmission is hard to get in gear, or if it pops out of gear under acceleration, a repair bill of several grand soon follows. Inspect the lower front air dam because it ducts air into the radiator: If it’s damaged, the engine may have overheated. Another potential trouble spot is the battery—if it ever leaks, the acid usually eats the engine’s computer. Benson has had just one problem: A faulty body-control module (which performs a variety of functions including traction control) cost him $600 to replace.

The Z06 seems to goad many owners into taking part in track days—once that bug hits, owners learn that going fast can cost money. Brake rotors are affordable at about $100 each, but a set of pads runs twice that. And tires are very pricey: Four of the original Goodyears run more than a grand. At least owners are less likely to crash their cherished Z06s if they can remember to use the excellent stability-control system, standard on all of them. The first-year models are usually a good bit cheaper because they had 20 fewer horsepower (385) than the ’02–04 models. But either way, it’s a helluva way to go fast on the cheap.

Is it safe to assume that car owners who lend auto writers their personal vehicles to hammer mercilessly on a track probably don’t coddle their cars themselves? While swapping stories one night at dinner, we asked Daniel Palacino, owner of the Ram SRT10 shown here, how far he’d seen the needle on his speedometer go.

“About a buck and a quarter,” he deadpanned, quickly adding, “I’ve got plenty of other cars to screw around in—this is my work truck.”

We laughed, but Palacino was serious. He’s a carpenter. A year ago, he walked into a Dodge dealership planning to buy a four-door four-wheel-drive Hemi-powered Ram to haul lumber and tow his trailer but left driving an SRT10 pickup with 13,000 miles on it, for which he’d paid $27,700. He’s put on another 30,000 miles since then, most while hauling tools and lumber, many pulling a trailer (though Dodge says not to tow with the SRT10), and more than a few with the throttle mashed flat and an opponent screaming to redline in the adjacent lane.

Despite its working life, this 2005 truck feels remarkably solid. The interior is clean and well preserved, and the heavily bolstered XXL Viper seats are still firm and supportive. The bed is a mess from the truck’s daily labors, but the sheetmetal is unblemished.

Palacino’s only problem was a failed clutch slave cylinder at 20,000 miles that was covered under warranty. No one writing on Internet forums reported this problem, and none of the three dealers we spoke with had encountered it before.

As much as a lumberyard may not be the natural habitat of this 500-hp exotic Ram, neither is a racetrack. It’s fast in a straight line—we recorded 0 to 60 mph in 4.9 seconds and the quarter-mile in 13.6 at 105 mph in our original test—but the clutch travels more than LeBron, and the shifts are weeks long. The shifter and knob could stand in for the bat and ball at a Thursday night softball league. The brakes were grabby at first but went soft on us after about 15 laps, likely due to the Ram’s 5100-pound curb weight.

The steering is twitchy, but the SRT10 moves surprisingly well for its size. It defaults to mild understeer in hard cornering, but poke the gas a little and the Ram sashays into nicely controllable oversteer. From such a high throne, it feels like you’re riding a slightly sedated rodeo bull.

Our first encounter with the Viper-hearted Ram polarized our office the way only something this utterly bizarre could, but this time the logbook was filled with nothing but praise. Despite being so out of place on a road course, the SRT10 won us over with its sheer ridiculousness, straight-line prowess, and the glorious trumpet of the big V-10. It’s the automotive equivalent of being at your hillbilly cousin’s wedding when you give a hearty rebel yell and join in the square dance. You know it’s ridiculous and you feel a bit foolish, but it’s shameless, giddy fun all the same.

In our original road test, John Phillips wrote: “I’m willing to accept the concept of a 153-mph hot-rod truck the day I see it carrying a load of drywall to a job site, you know?”

The time has come, John.

QUOTES FROM THE PAST: The Ram SRT10

“The shift lever, which is roughly the size of the late John Holmes’s . . . [You’ve been warned, Yates—Ed.], rattles under hard acceleration like a porn star’s vibrator.” —Brock Yates, FEBRUARY 2004

"Fuel mileage? With high-test still less than $2 per gallon and OPEC on the ropes, who the hell cares?” —Brock Yates, IBID.

________________________________________________________________________________________

FEAR FACTOR

Perhaps you’ve noticed that gas is no longer the price of rainwater, and you’ll be lucky to squeeze 10 miles from a gallon of it. Figure $150 for an oil change (10 quarts of Mobil 1 synthetic). To have a dealer replace the brake pads and turn the rotors is about $450 per axle. Add another $300 per end for new rotors.


_____________________________________________

One hundred and eighty-three thousand. That’s how many miles have been rolled up on the odometer of the 1999 E55 AMG currently owned by Bryan English. English has driven the hell out of the big Benz, accruing all but 16,000 of those miles since purchasing the car in 2003. His E55 feels extremely tight and is in exceptional condition despite the high mileage, a testament to how well English takes care of his ride as well as to the Germans who built it. Squeaks and rattles are nonexistent, and the Mercedes dealers and independent specialists we’ve spoken with characterize the W210 E55 as bulletproof.

Still, bulletproof engineering combined with attentive maintenance couldn’t keep every problem at bay. English was forced to replace the transmission in late 2006, costing him $6500 (a Mercedes dealer we spoke with suggested $5660 should get the job done). More-recent services resulted in replacement of a ball joint, a few bushings, and the cam and crank sensors, and we’re told to expect bills totaling near $1000 for that kind of work.

Unlike most of the cars on this list, the E55 is meant more for screaming along the autobahn than for ripping off laps at the local raceway, and it wasn’t very happy at GingerMan, especially so because it wore all-season tires, stock-spec brake pads, and the original shocks. But it’s not as if the AMG handles like a bucket of pudding.

The steering is dead accurate and provides more feel than a handsy high-schooler; it’s the sort of communication that’s rare in most cars made a mere decade later. The ride is firm but never harsh, and there’s no inclination toward dive, squat, or roll. The real superstar isn’t the fantastic chassis, though—it’s the 5.4-liter V-8, a masterpiece of a motor that pumps out 349 horsepower and 391 pound-feet of torque.

Hammer the throttle and you realize in a hurry that the E55 can get down. Our original testing resulted in 0-to-60-mph times ranging from 4.9 to 5.5 seconds, and English’s well-worn veteran feels every bit as quick. The V-8 doesn’t deliver quite the same sledgehammer-to-the-sternum punch as do today’s V-8 AMGs—they currently have at least 74 more pound-feet of torque—but the E55 does share their ability to pull like a drop-kicked mule, and it actually gets stronger as you near the top end. The five-speed automatic (no manual was offered) is as smooth and silken in operation as any of Mercedes’ modern gearboxes.

The W210 E55 AMG may be the ultimate Q-ship; it’s a perfect combination of performance, ride, luxury, and low-key looks. The closest you’ll come today is to visit a Mercedes dealership and drive away in a brand-new E63 AMG, but at nearly $90,000, it’s almost 20 grand more than what the E55 cost when new. Covered with flares and vents, the E63 isn’t inconspicuous, either. Pick up a well-cared-for E55, on the other hand, and you’ll get 80 percent of the car for one-quarter of the money. That’s one heck of a discount for what we once called “the best E-class ever.”


_____________________________________________

A Porsche needed to be on this list. Admittedly, a first-generation 986 Boxster might be more fun on a track, but the almost mystical allure of an air-cooled flat-six overcame the pull of a water-cooled modernist.

We tapped Victorymotorcars (www.victorymotorcars.com) of Houston, Texas, a purveyor of used Porsches, for a 964 model of 1989–94 vintage. They kindly agreed to extend to us a 1990 Carrera 4 with 84,000 miles on the odometer. Salesman Jason Fletcher came along to look after the car because it had already been sold, for $25,500, which didn’t stop one of our crew from spinning it. For the record, examples of the last generation of air-cooled 911s—993s—sell for well over $25,000.

Victory specializes in air-cooled Porsches, selling about 40 of them per month. The flagging dollar, weak against foreign currencies, is a big help to Victory’s sales, as 25 get shipped overseas, mainly to Europe, while five go to Canada and the remaining 10 are sold in the U.S.

With any old Porsche, the cost of keeping it on the road is a very real fear, though some wear items are not startlingly expensive. A set of Porsche brake pads (which works for the front or rear) costs about $135, and rotors, good for any corner, run $155 apiece. The original Bridgestone tires are no longer made, but a replacement set of Potenza RE-01Rs is less than $500. Everything else gets expensive in a hurry. A catalytic converter touches tuition-payment territory at $1800, and Porsche mechanics charge at least a hundred bucks an hour.

There are a few genetic problems associated with the otherwise indestructible powertrain of the 964. The valve covers came painted from the factory. This paint eventually chips off, and the seal between the head and valve cover weakens, causing a leak. The repair (removing and sandblasting the covers) costs about a grand. Another common failure is the anti-lock brake pump. When this goes, find $2000.

When we first drove these cars nearly two decades ago, rear-drive 964s hit 60 mph in less than five seconds, a feat still respectable by today’s standards. Cosmetically, the 18-year-old 911 was showing its age. The headliner was sagging, the switchgear showed signs of repeated use, the power-mirror button was missing, and the paint was, as they say, “Good from far but far from good.” Still, the 911’s signs of age could not diminish the driving enjoyment.

Compared with today’s 911s, the steering feels heavy and deliberate. The awkward floor-hinged pedals take some driver adjustment, especially for smooth heel-and-toe downshifts. The handling is less than sharp. But when the air-cooled 3.6-liter boxer engine is roaring, all of the car’s faults—dynamic, cosmetic, ergonomic—are simply drowned out by the urgent sound of the engine and a feel that can only be provided by an old Porsche.

The appeal of a 911 goes deeper than the basic connection between man and machine. Because it’s one of the most iconic sports cars of all time, there is a certain level of celebrity associated with owning a 911, something that’s difficult to equal in any other car purchase. Still, don’t buy one without a good service history or at least a thorough inspection by a mechanic.


_____________________________________________

What you see here is as rare as a rock star groupie who’s also a virgin: a Toyota Supra Turbo in original condition. Rarer still: a Toyota Supra Turbo that’s had multiple owners. Many—most?—of the force-fed Supras from the ’94–98 era have been subjected to the tender mercies of tuners, professional and not-so-professional, who have tweaked up the boost of the sequential twin turbos feeding the car’s 3.0-liter straight-six well beyond the stock max of 11.6 psi, frequently to the threshold of meltdown.

Introduced in 1993 as a 1994 model, the Supra Turbo was rated at 320 horsepower and 315 pound-feet of torque. It was pretty hot stuff for the day, capable of 0 to 60 mph anywhere from 4.6 to 5.2 seconds. But with a base price over $40,000, it was also expensive, and Toyota sold only 8611 fourth-gen Supras before pulling the plug at the end of the 1998 model year.

This 1994 example is owned by Jeremy Feller of Carmel, Indiana. He’s a 33-year-old field clinical engineer for CVRX, a company that produces medical equipment. He bought the car just three weeks before our derby, and it came to GingerMan as acquired, including a mismatched set of all-season tires.

“I haven’t done anything to it,” he said. “Yet.”

Feller found the Supra in Chicago and paid $33,000 for it. He said he researched others, some below our $25,000 target, but popped for the Chicago car because it was in original condition—clean, free of rust and dents, well preserved within, and untouched under the hood. The car had just more than 60,000 miles on the odometer, accumulated by three previous owners in locations ranging from New Jersey to Washington state before Feller brought it home to Indiana.

We couldn’t drive the Supra as hard as some of the other cars, owing to its odd collection of tires—Yokohama A520s front, Pirelli P600s rear, well worn at both ends. Nevertheless, we were impressed with the Toyota’s solidity—no squeaks or rattles—and with its benign ride and handling. Braking was just so-so, limited by the tires and stock pads, which began to stink and fade after just a couple of laps. And a reluctant upshift to sixth gear marred an otherwise snick-snick transmission.

But the turbos asserted themselves decisively above 4000 rpm, yielding a gratifying rush, though there were a couple of testers who expected a little more punch.

This last reaction may be due in part to experiences with Supras boosted to double stock output.

Feller, a Ford man who also owns a 1969 Boss 429 Mustang, a ’68 Shelby GT350 convertible, and a 1970 429 Cobra Jet Torino, plans to make the Supra his daily driver and intends to make increased power one of his first priorities.

“Nothing radical,” he said. “Not like all those guys who go for 1000 horsepower.

“I’d just like to get about 400 horsepower, which is very easy to do in these cars. Uh, 400 at the rear wheels, that is.”

Chevrolet Cruze first look- to replace Cobalt.


Here is the first official look at the 2011 Chevrolet Cruze that will replace the Cobalt as GM’s bread-and-no-butter compact car.

This all-new sedan offers us the first look at the next generation of GM’s Global Compact Vehicle Architecture (Delta 2). The global car replaces the Cobalt in North America and the Daewoo-built Chevy Lacetti/Nubira in Europe.

Visitors to the 2008 Paris auto show in October will see for themselves the concept version of this sedan that will eventually be joined by the replacement for the Pontiac G5, as well. And we fully expect hatchback versions in North America down the road, as GM plans to make the body style for Europe.

The five-passenger sedan is 180 inches long, and slots between the subcompact Chevrolet Aveo and the mid-size Chevy Malibu in the lineup. The Cruze will be powered by GM’s new family of direct-injection four-cylinder engines, likely ranging in displacement from 1.4 liters to 2.0, some of which will be turbocharged. The expectation is about 40 mpg, or better.

The rollout begins in Europe, where the Cruze will begin production early in 2009 for sale in the spring as a 2010 model. North America must wait until a mid-2010 start of production at the Lordstown, Ohio, plant that makes the Cobalt and G5. GM will retool the plant for the new models.

We expect the current Cobalt to be offered through June 2010, with the 2011 Cruze built alongside it until the Cobalt is phased out.

The Cruze was engineered at GM’s Russelsheim, Germany, development center, and was designed in Korea by GM Daewoo. The car will be assembled in plants around the world, including the U.S., Mexico, various parts of Europe, South Korea, and Brazil.

2010 Jaguar XF-R spied in Death Valley


After seeing prototypes running around England, we figured it was only a matter of time before we would catch up with the 2010 Jaguar XF-R in Death Valley. Running solo in a new shade of silver, this high-performance version of the standard XF sedan is designed to give Jaguar a true super sedan to compete with the likes of the BMW M5 and the Mercedes-Benz E63 AMG.

This latest XF-R prototype wears many of the same upgrades as the earlier test mules. The deeper airdam up front is the most obvious upgrade, as the air intakes appear slightly larger than those on the standard model. It also looks like a pair of hood intakes have been added as well.

There are new, more aggressive rocker-sill extensions as well, although the wheels appear to be the same set of optional 20-inch items available for the standard XF. In back, a set of quad tailpipes is another obvious tip-off to this XF's high-performance engine hardware.

So what's under the hood? All indications point toward a new supercharged 5.0-liter V8. It's an all-new engine that will filter down to the entire Jaguar lineup in one form or another, not to mention Land Rover's upcoming SUVs. In the XF-R, it will likely produce around 500 horsepower, a number that will put it right in line with the rest of the luxury super-sedan crowd.

Expect to see the official debut of the 2010 Jaguar XF-R early next year, with sales beginning by the spring of 2009.

Fannie Freddie plunge again- nearly 30%

NEW YORK (CNNMoney.com) -- Battered mortgage giants Fannie Mae and Freddie Mac took yet another hit on Wednesday as concerns grew about a possible government bailout.

Shares of Fannie (FNM, Fortune 500) and Freddie (FRE, Fortune 500) each tumbled about 27% in afternoon trading.

Prior to today's declines, shares were already down 20% this week. Each has plunged nearly 90% in 2008.

Wall Street has been concerned about Fannie and Freddie's need to raise capital, and the possibility of a government bailout that could make the stocks worthless for private investors.

Fannie and Freddie are crucial to the housing market. The two government sponsored enterprises collectively own or back more than $5 trillion in mortgages, or half the nation's mortgage debt.

Both companies have been losing money for the past few quarters due to the subprime mortgage meltdown and steep declines in housing prices.

Fannie CEO Daniel Mudd tried to alleviate concerns about a government bailout on Wednesday, when he told National Public Radio that no such plan was imminent.

"They haven't offered anything and we haven't asked for anything," said Mudd to NPR. "I don't anticipate that they will do that."

In the latest sign of trouble, Freddie had to pay a borrowing premium Tuesday, when it issued $3 billion worth of five-year debt. Freddie's interest rate was 1.13 percentage points higher that the standard federal government rate, and was a 10-year high for the lender.

On July 30, President Bush signed into law a housing bill to boost Fannie and Freddie. The bill gave the Treasury Department the authority to loan unlimited amounts of money to Fannie and Freddie and also allows for Treasury to buy up shares of the two firms if necessary.

The price tag on a government bailout is likely to be costly, with estimates ranging from $25 billion to $100 billion.

Fannie spokeswoman Amy Bonitatibus declined to comment on the company's stock activity or any plans to meet with the Treasury about a bailout. Spokesmen for Freddie Mac were not immediately available for comment.

A spokesperson for the Treasury Department had no comment about Fannie or Freddie

Peugot's Missing Link hybrid concept




PARIS — Peugeot seems to be channeling its aggressive side, if the photos released on Wednesday of its new hybrid concept car are any indication. The new concept, dubbed "RC" for the time being, will be formally unveiled at the 2008 Paris Auto Show.

Peugeot said the full name of the car will be disclosed later. The French automaker says the GT coupe is "the missing link between the RC and concept cars revealed in 2002 and the 908 RC." The RC concept cars, introduced at the 2002 Geneva Auto Show, were low, lean 2+2 coupes with steeply raked windshields and a catlike look. They were shown in gasoline and diesel variants.

The Peugeot 908 RC, introduced in Paris in 2006, took a little criticism from such lofty quarters as Car Design News, which called the sensuous vehicle "another Ferrari-esque flight of fancy that will have no consequence for future Peugeots."

Details are sketchy on the new four-seat concept. Peugeot said it has "highly innovative hybrid architecture" with a potential maximum power output of 313 horsepower and low or zero emissions, depending on whether it's operating in the combined mode or in electric mode only.

What this means to you: Peugeot says the concept is a "working laboratory," but only time will tell if it ever sees the light of day. — Anita Lienert, Correspondent

Google Investing Over $10 Million in Geothermal Energy

google
Geothermal energy has finally hit the big time. Google.org, the philanthropic arm of Google, announced today that it is investing $10.25 million in an energy technology called Enhanced Geothermal Systems (EGS). The funding will also go towards geothermal resource mapping, information tools, and a geothermal energy policy agenda.

And it looks like Google made a wise investment choice. According to an MIT report on EGS, only 2% of the heat beneath the continental US between 3 and 10 kilometers (depths we can reach with current technology) is more than 2,500 the annual energy use of the United States.

While traditional geothermal energy relies on finding natural pockets of hot water and steam, EGS fractures the hot rock, circulates water in its system, and uses the steam created from the process to create electricity in a turbine.

The investments will go towards three institutions: AltaRock Energy, Potter Drilling, and the Southern Methodist University Geothermal Lab.

Google’s funding may just be the push we need to really get geothermal off the ground, once again proving that government funding and initiatives can’t do everything. Substantial change can only come when private investors and corporations decide to help out—whatever their motives may be.

8 Easy Steps to Banish Bad Breath

Change Your Breath From Bad to Good

Bad breath is embarrassing, unpleasant, and all too common. These eight easy tips will sweeten your breath for good.

By Sarah Albert
WebMD Feature

We've all found ourselves chatting with someone whose breath could easily wilt a flower. With more than 90 million people suffering from chronic bad breath (also called halitosis), that's a lot of wilted flowers. If you (or someone you regularly smooch) has an attack of bad breath that even Altoids won't fix, try these eight simple tips to fix the problem.

Don't let your tongue become a dirty carpet.

Bad breath often strikes when people aren't properly taking care of their oral health. The odor is usually caused by decaying food particles and bacteria in your mouth. That's why brushing and flossing your teeth is so important, but don't forget to gently brush your tongue to get rid of even more bacteria.

A clean tongue goes a long way to warding off bad breath, says Stephen Z. Wolner, a dentist in private practice in New York City. "Your tongue microscopically is like a shaggy carpet. There are millions of filaments on your tongue that trap tiny food particles and bacteria," he says. Get in the habit of regularly cleaning your tongue using a toothbrush, the edge of a spoon, or a tongue cleaner. If you have any mouth guards or oral devices, make sure to clean them thoroughly before putting them back in your mouth.

Mouthwash isn't a bad idea, but it's only a temporary fix. Granted, a little mouthwash comes in handy before a romantic dinner for two, but it masks the odor instead of tackling the source of your problem.

Chew gum like it's going out of style.

Believe it or not, saliva is your best weapon against bad breath. That's why dry mouth, often caused by certain medications or medical conditions, leads to odor problems. By washing away food particles and bacteria, saliva helps to eliminate odor, too.

If you're wondering why your breath stinks in the morning, it's largely because saliva production slows while you sleep, allowing particles and odor to linger longer. That's where sugarless gum comes in handy, as chewing it will stimulate saliva production. Mints, on the other hand, don't usually stimulate saliva production and only temporarily mask bad odor.

"When you chew gum it makes you salivate, and the more saliva you have in your mouth the fewer bacteria you have. It not only mechanically washes bacteria out, but we have antiseptic and enzymes in our saliva that kill bacteria," says Wolner.

While anything that makes you salivate will improve your breath, a gum that is sweetened with xylitol is your best option. Xylitol is a sugar substitute that not only increases salvation but also works to prevent bacteria from replicating in the mouth.

Choose cinnamon -- it's sweeter.

A recent study of the cinnamon-flavored gum Big Red found that cinnamon might have breath-odor fighting abilities. Unlike other flavors, cinnamon is not just a cover-up, Wolner tells WebMD. In fact, he says, an ingredient in the flavoring appears to actually decrease the bacteria in your mouth. The only problem is that sugar gums are bad for your teeth, so stick to sugarless cinnamon-flavored gum instead.

Drink more water.

Wolner says the older you get the more likely you are to get dehydrated. You might not even notice you're thirsty, he says, so make drinking water a habit, because water will help keep the bacteria in your mouth to a minimum. Drinking water has a lot of health benefits, and preventing bad breath is one of them.

Rule out rare causes for bad breath.

While most bad breath can be banished with simple hygienic steps, there are times when dental or medical conditions might be the culprit. Make an appointment with your dentist if an unsavory odor takes residence in your mouth.

"If there is a persistent odor in your mouth, and you know it's not from the pasta you ate last night, see a dentist," Wolner tells WebMD. Your dentist will be able to pinpoint any cavities or decay, or even periodontal (gum) disease, that might be causing your bad breath.

Because on rare occasions bad breath can signal a larger problem, including infection, and even kidney or liver failure, you should also visit a doctor if your dentist doesn't find a cause for your bad breath problem.

Have a slice of bread.

If you're on one of the many popular low-carb diets, remember that bad breath or "ketone breath" is a potential side effect when you always have that burger sans bun. You can try different methods of masking the odor, such as gum or tart candies, but adding a few carbs to your daily diet might also do the trick.

Get a water pick.

You can't really clean your entire mouth with a toothbrush. "Using an irrigator or water pick cleans everything out around and under your gums and between your teeth," says Wolner. "If food lingers between your teeth where a toothbrush doesn't reach, it's fermenting." Next time you floss, take a whiff of your floss after you're done, and you'll have a good idea about what fermented or rotten food particles smell like.

Don't let bad breath go to your head.

If you think you have bad breath, get a second opinion. "A large proportion of people who think they're social pariahs with terrible breath don't have bad breath at all," says Wolner.

Meet the Boy Too Big for His Mom's SUV

This 12-Year-Old Boy Is Truly Unique and Truly Tall

By MARY HANAN

Ellensburg, Wash., is home to a truly unique young man: 12-year-old Brenden Adams, who is more than seven feet tall and, incredibly, still growing.

Brenden's unstoppable growth caused by mismatched chromosomes.

He towers over his classmates and even his teacher, Gretchen Holmstrom, who jokingly quipped, "I'm 5'9," so I never look up to sixth graders -- until this year…never say never!"

And though friends say Brenden is just a regular kid, he's obviously not like anybody else. He has to duck through most doorways and sit sideways at his school desk because his knees don't fit under it.

In his mom's sport utility vehicle, he has to fold down the second row of seats, sit in the third row and stretch his legs out over the middle row in order to sit comfortably. His shoe size? 18 and still growing.

Not Just a Tall Kid

Brenden is one-of-a-kind, and it's not just his height. Everything about him is different. His mom, Debbie Ezell, said he requires a team of doctors and multiple medical visits simply to stay on top of his ever-changing and expanding frame. He has enormous joints, fatty tumors, even extra teeth, 12 of which were recently removed.

Amazingly, his dad, Willie Adams, said there was no hint of any of this when Brenden was born at 7 pounds, 3 ounces and 19 1/2 inches in length. His mom says they first started to notice something was different at his 2 month check-up. "They said, these measurements just aren't right. He's too long," Ezell said. "And at four months, he had all of his teeth."

Then mom and dad got the news that any parent would dread. Doctors and medical experts told them they had no idea what was causing the problem with their child. "I still haven't seen anyone like Brenden," says Dr. Melissa Parisi, his geneticist at Children's Hospital in Seattle. Parisi has been treating Brenden since he was four years old, when, she said, "he was the size of a typical 8-year-old boy."

What's Up?

"I was terrified," his father said, "and no one could ever give us an answer what the outcome would be or what the expectancy would be."

Brenden's mom agreed, "That's the worst part¬ knowing."

For years, doctors continued to search for the source and an answer to Brenden's unstoppable growth. He went through multiple tests and X-rays as medical experts tried to determine what was going on inside Brenden's body.

Then, finally, a breakthrough -- when Brenden was eight years old and already the size of an adult.

"I have to say that the hematologists and oncologists here actually helped us figure it out," admits Parisi. "He has a very unusual rearrangement of his genetic material. It's what's called an inversion of chromosome-12 and it affects every single cell in his body."

Chromosomes, you may remember, come in pairs. But in Brenden's case, his 12th chromosomes don't match. Somehow -- experts still don't know why -- the middle of one of them broke off, flipped around and re-attached, disrupting a critical gene that controls growth. And that's what experts believe is causing Brenden's excessive growth and other symptoms and what makes his case the only one of its kind.

"This gene is functioning despite the regulation that it shouldn't be," said Dr. Gad Kletter, Brenden's endocrinologist at Swedish Hospital in Seattle. "It's over-functioning. He was predicted to be over eight foot tall."

Ending the Neverending Growth Spurt

Now that doctors finally figured out what was causing Brenden's skyrocketing height, they still had another mystery to solve: how to stop it? And since Brenden is believed to be the only person in the world with the condition, there was no clear-cut answer.

Then, Kletter had an idea that seemed a little crazy -- shots of testosterone to jump start puberty and speed up Brenden's growth. It's puberty, he explained, that signals the body to stop growing.

"We induced puberty," explained Kletter, "to fuse the bones and stop the growth."

And so far, the shots seem to be successful. Brenden's growth has slowed down.

Living With a Giant

To make life a little easier at home, Brenden's mom had a home built specifically to fit someone of Brenden's enormous proportions.

"It's a lot easier going through the doors and stuff than the last house we had," Brenden said. "The doors are a lot taller and so are the ceilings."

Coincidentally, on the day ABC News visited Brenden's school, his class was working on a soul-searching exercise. Perhaps not surprisingly, Brenden wrote that he wishes people would see "how he's just like everyone else."

Happily, some already do.

"He's really nice and caring," a friend, Tucker, said.

His stepsister, Sierra, added: "He's an extremely good person."

What does the future hold for him?

"It's unknown," said Kletter. "No other case is reported, nothing to look at -- it's an uncharted sea."

Luxury Living at Burning Man

If you plan to not only survive but thrive in the harsh environment of Burning Man, you'd be well-advised to rise above your REI tent.

Luxury living on the playa requires relaxing in the heat of the day and staying warm on cold nights. You've got to be able to transport the structure in and out of Black Rock City, Nevada -- the temporary city that rises out of the desert each year during the mammoth art festival -- and assemble it in unpredictable conditions. It must be able to survive brutal dust storms that can arrive without warning and last for hours.

Last year, I discovered some clever options for living large on the playa without leaving a big footprint. Though all three solutions were rather low-tech, none would be accessible to Burners without the internet or open source.

Hexayurt

Originally designed as refugee housing, a Hexayurt can be built for $200 from fire-safe insulation boards and industrial tape. The Hexayurt Project follows a free and open source model; plans can be downloaded at the project's website.

I visited two of these innovative shelters last year at Burning Man. One belonged to Lindsey Darby, a 21-year-old college student and co-designer on the Hexayurt Project. The other belonged to Kevin Price, a 47-year-old computer technician from Mesa, Arizona, who said he discovered Hexayurts two weeks before Burning Man. "I was thinking of all the ways the tent would be awful. I went right to it: no prototype." He bought all the parts, cut them in his driveway and assembled them on the playa.

Inside, both Darby's and Price's Hexayurts were spacious, quiet and cooler than expected in the hot afternoon sun. According to Darby, her fold-up Hexayurt took only 30 minutes to assemble on the playa, and its impressive R-value allowed her to sleep later than her neighbors.

"I've always stayed in a Hexayurt on the playa, never in a tent, so I've always been able to stay in bed until 10 or 11 [a.m.]," she said. "But I did notice that I was always the last one up!"

Vinay Gupta, the Hexayurt's inventor, said: "It's like having an entire extra day at Burning Man. You can go to bed at 3 or 4 in the morning, get up at noon, and you're still human at the end of the week."

Indian Desert Tent

After a decade of camping in tents and borrowed camper trailers, San Francisco burner John "Jocko" Magadini decided to treat himself to a little bit of luxury in Black Rock City. Though the camper -- with its stove, running water and cushy seating -- was comfortable, Magadini said it left him feeling "not as one with the playa."

"I felt a bit removed and also maybe a little bit common because so many people do that," he said.

Following an extensive online search for tents of all sorts, he stumbled across an Indian Desert Tent. It cost just under $1,000 for the tent, and another $500 for shipping, which took six weeks.

"They told me it would take a little over an hour [to set up], and one person could do it," said Magadini. "It took two people and three hours. But once I got it up, I couldn't believe it. It was so absolutely bomber."

Made of heavy-duty cotton canvas and lined with printed sheeting, the yurt-shaped tent repels water and wind and has plenty of room inside for guest seating, Magadini's queen-size inflatable bed and a full rack of costumes. Plus, it stood up to Burning Man's rugged environment. "After a week and a half and many dust storms, there was close to no dust inside," he said.

Playatech Furniture

Arthur "Sunshine Dreamer" Zwern, a 48-year-old entrepreneur and inventor from San Jose, California, got tired of seeing so many sofas going into the landfill after Burning Man, yet his wife, "Glimmer," said she wanted extra seating on the playa. So he designed a line of DIY "period furniture" made from 4-foot-by-8-foot sheets of plywood. Plans for cutting the plywood to build a Precarichair, a Ploset, a Plantry, Plykea Shelves and many more Black Rock essentials are available at Playatech for a small donation, which benefits Black Rock Arts Foundation.

Once cut, Playatech furniture requires no tools or hardware for assembly and can be stacked flat for transport before and after use. "If you have to rebuild everything again each year, it gets a little tedious," said Zwern.

"We burn a little bit of our furniture each year, as it wears out," he admitted.

Describing both the Hexayurt and Playatech, he said: "We wanted to develop the technology to build a city in a week, with no infrastructure, and with two to three natural disasters a week." He insists his furniture is sturdy enough to dance on and to have sex on -- perhaps the next most important qualities in Black Rock City.

Bonus: Five Items a Burner Can't Live Without

  • 1) Glow: Being seen at night is the best way to avoid getting crushed by an art car or T-boned by another biker. Bring enough glow sticks for you and your bike to wear several pieces each evening. Better yet, get battery-powered EL wire and reuse it every night.

  • 2) Bicycle: You can't drive on the playa, and there's never an art car when you need one. So gussy up your bike and bring it along. The more elaborately it's decorated, the less likely it is to get lost.

  • 3) Dust mask and goggles: Fierce dust storms are the norm at Burning Man. These Steampunk goggles from the Neverwas Haul crew look cool, but standard-issue eye protection from Home Depot will do the job. Carry goggles and a scarf or dust mask, and be ready to put them on at a moment's notice.

  • 4) Earplugs: The party never stops at Burning Man, but sometimes you'll wish it would. Earplugs actually make it possible to sleep, for a few hours at least.

  • 5) Water: No water is provided at Burning Man. Bring all you'll need to drink, bathe, cook and wash dishes: an estimated 1.5 gallons of water per person per day.

  • Federal Judge tosses MIT students' Gag order

    A federal judge in Boston this morning let expire a temporary gag order against three MIT students who were prevented from presenting a talk on security vulnerabilities in the Boston subway's fare tickets and cards.

    U.S. District Judge George A. O'Toole, Jr., vacated the temporary 10-day restraining order that another judge had instituted more than a week ago against the students and which was scheduled to expire today. District Judge O'Toole also threw out a request by the Massachusetts Bay Transportation Authority (MBTA) to obtain a preliminary injunction against the students to expand the restraining order beyond the original 10 days.

    "It's great news for the free speech rights for these students," said Rebecca Jesche, a spokeswoman for the Electronic Frontier Foundation, which represented the students. "Although it's extremely unfortunate that the students were not allowed to give their talk at DefCon."

    The students had planned to give their talk last Sunday at the DefCon hacker conference in Las Vegas. The talk was based on a research project and paper that they had submitted for a class taught by their MIT professor, noted cryptographer Ron Rivest. The paper had earned them an "A."

    A week before the scheduled DefCon talk, the students had met with the MBTA to discuss the transit authority's concerns that the students would teach others how to defraud the system. The students reassured the transit authority that they would withhold key information from their talk and would not be teaching someone how to defraud the system. They were under the impression after that meeting that the MBTA was fine with their talk. They were then surprised to learn, two days before their presentation, that the MBTA had filed a suit and a motion for a restraining order. When a different federal judge, District Judge Douglas Woodlock, granted the restraining order, the decision was criticized as an unconstitutional prior restraint of speech.

    In granting the restraining order, District Judge Woodlock had invoked the Computer Fraud and Abuse Act, implying that the students' speech about how the MBTA system was vulnerable to hacking was equivalent to someone actually hacking the MBTA system -- or at least aided that illegal hacking activity.

    District Judge O'Toole, however, said that the Computer Fraud and Abuse Act does not apply to speech and that the MBTA had failed to supply sufficient proof to merit other claims with regard to the statute, to merit a restraining order or preliminary injunction.

    "It was definitely unfair to use that statute to silence the students," Jesche said. "We certainly hope the next time that people are allowed to present their important research instead of being silenced by bogus lawsuits."

    Zack Anderson, one of the students sued in the case (and the second person from the right in the picture above), was elated by the judge's decision today.

    "We're glad the court actually saw things as they should be," the 21-year-old told Threat Level. "We're glad the court read the law correctly."

    Although the restraining order has gone away, it doesn't mean the students are completely in the clear. Still standing is a lawsuit the MBTA has filed against them, accusing them of hacking its system and causing damages.

    Anderson said the students regret that they weren't allowed to give their presentation last Sunday but have no intention of giving the talk anymore.

    "All the material we were going to talk about has been made public ... and more," he said, referring to the fact that their presentation slides as well as a confidential report describing vulnerabilities with the Boston system were posted online after the judge granted the restraining order.

    Anderson maintains that the students never planned to present key information that would have allowed someone to defraud the MBTA system and says they still stand by that.

    "Despite what's happened, and the animosity the MBTA has brought toward us," he said, "we don't want people to defraud them."

    When asked if he and the other students ever created bogus MBTA cards and used them to get free rides on Boston's T subway, Anderson declined to respond.

    "I can't really comment on the actual means that we used," he said. "It's probably not a good idea to comment on that. We certainly did not get free fare. We had to spend several hundred dollars on buying tickets to look at the data structure. Far more than we ever would have used."

    The MBTA, in a hearing on the case last week, had asked the court to require the students to hand over the class paper they had submitted to their MIT professor, Ron Rivest, about their research of the MBTA transit system. The students declined to hand over that paper but they did provide the MBTA with a 30-page sealed report, which Anderson says "went over the entire universe of our knowledge of the system, even more than the class paper has."

    A cure for Pandemic Flu- replicating 90 year old antibodies

    Scientists have succeed in replicating flu pandemic antibodies from 90 year old survivors

    The H5N1 Virus: Photo by Quiplash! (CC Licensed)

    Ninety years ago the Spanish flu swept across the globe, killing between 50 and 100 million people in only a few months. Since then, the specter of another flu pandemic dealing death and woe around the world has periodically terrified the medical and popular communities. But scientists searching for ways to prevent a similar outbreak in the form of the H5N1 bird flu have found a cure for the deadliest flu in the most unlikely place: nonagenarian immune systems.

    A new paper in the journal Nature confirms that a team of doctors has succeeded in isolating pandemic-flu killing antibodies from 90+ year old survivors of the Spanish flu outbreak. To test whether or not the antibodies still worked, the doctors injected the immune cells into mice, and then dosed the mice with preserved copies of the 1918 flu recovered from frozen victims of the Spanish flu that had been buried in Alaskan permafrost. Within those mice, the antibodies and the virus renewed a microscopic battle that had lain dormant for almost a century. The mice that received a high dose of the antibodies lived, while mice that received a low dose of antibody, or none at all, died as expected. While the authors of the paper indicated that understanding the immune system’s ability to “remember” infections for so long could be useful in studying all manner of viral infection, it is unlikely that antibodies synthesized from survivors would be able to immediately help in a future bird flu pandemic. The 1918 Spanish flu and the modern Asian bird flu are different species, and the antibodies are probably not compatible. Rather, by understanding how the body produces and preserves flu antibodies over a lifetime doctors hope to be able to develop more effective vaccines specific to viruses like the bird flu. Currently, the common flu kills 30,000 Americans a year, so developing effective vaccines is important even without an outbreak of the more deadly pandemic strain of the disease

    A Waterproof World

    A universal liquid-repeller makes anything dunk-proof

    Wet Sneaker: Photo by Satoshi

    Today you can buy a rubber boot or a cellphone with rubber seals to keep water out. But a new treatment called Ion Mask promises to make any gadget or clothing item waterproof and stainproof without changing its appearance.

    THE TECH

    The process uses a gas, called a fluorocarbon monomer, that’s similar to ingredients in Scotchgard and Gore-Tex. Zapping the gas with radio waves excites electrons in its molecules, making them more reactive and able to bond to almost anything. The resulting waterproof layer is too thin to affect a material’s breathability or disrupt the flow of electricity to, say, a USB port.

    TESTING

    Hi-Tec’s Altitude Ultra boot is the first product with the coating. But waterproofing a leather boot is easy. So we asked P2i, the company behind Ion Mask, to send us treated samples of a mesh-fabric sneaker that we doused with water [above] and cotton fabric that we splattered with wine [below]. No treated electronic products were available at the time; but P2i expects small gadgets such as earbuds to appear later this year.

    RESULTS

    Ion Mask worked as promised. A generous splash of water didn’t penetrate the sneaker, and red wine left no stain on the fabric.

    Hussman Funds Weekly Market Comment



    Dr. Hussman's easy to read weekly market comments are a great insight into economics and finance. His mutual fund company uses derivatives to hedge long positions creating absolute returns(aims to maximize returns on a risk adjusted basis- Sharpe ratio) for their two mutual funds. Further, he is fully invested in his own funds(eats his own cooking). I do not nor have I ever owned any shares in the two funds. However, I can recommend the company without reservation.
