How Gadgets helped the Mumbai Attackers

By Noah Shachtman

Article109071902a4c96a000005dc862_4 The Mumbai terrorists used an array of commercial technologies -- from Blackberries to GPS navigators to anonymous e-mail accounts -- to pull off their heinous attacks.

For years, terrorists and insurgents around the world have used off-the-shelf hardware and software to stay ahead of bigger, better-funded authorities. In 2007, former U.S. Central Command chief Gen. John Abizaid complained that, with their Radio Shack stockpile of communications gear, "this enemy is better networked than we are." The strikes that killed at least 174 appears to be another example of how wired today's "global guerrillas" can be.

As they approached Mumbai by boat, the terrorists "steered the vessel using GPS equipment," according to the Daily Mail. A satellite phone was later found aboard.

Once the coordinated attacks began, the terrorists were on their cell phones constantly. They used BlackBerries "to monitor international reaction to the atrocities, and to check on the police response via the internet," the Courier Mail reports.

The gunmen were able to trawl the internet for information after cable television feeds to the two luxury hotels and office block were cut by the authorities.

The men looked beyond the instant updates of the Indian media to find worldwide reaction to the events in Mumbai, and to keep abreast of the movements of the soldiers sent to stop them.

Outside of Leopold's Cafe, "one of the gunmen seemed to be talking on a mobile phone even as he used his other hand to fire off rounds," an eyewitness told The New York Times.

The terror group then took credit for the bloodshed with a series of e-mails to local media. They used a "remailer" service to mask their identities; earlier attacks were claimed from cyber cafes.

Pentagon puts $22 Million into Guided Bullet

By Noah Shachtman

Specwarnetcom50pic What if a sniper could fire a bullet that changed course in midflight, to hit its target? The Pentagon is handing out nearly $22 million to try to find out.

Darpa, the Defense Department's far-out research arm, announced a pair of contracts last Tuesday, to start designing a super, .50-caliber sniper rifle that fires guided bullets. Lockheed Martin received $12.3 million for the "Exacto," or Extreme Accuracy Tasked Ordnance, project, while Teledyne Scientific & Imaging got another $9.5 million.

If the system works, it'll "provide a dramatic new capability to the U.S. military," Darpa says. "The use of an actively controlled bullet will make it possible to counter environmental effects such as crosswinds and air density, and prosecute both stationary and moving targets while enhancing shooter covertness. This capability would have the further benefit of providing increased accuracy and range while reducing training requirements."

"In other words," Danger Room's Sharon Weinberger wrote last year, "it would be the ultimate sniper round."

Darpa won't say, publicly, how far, how long and how accurate they want the new bullets to be — all that information is classified. But they will say that Exacto should contain a next-gen scope, a guidance system that provides information to direct the projectile, an "actively controlled .50-caliber projectile that uses this information for real-time directional flight control," and a rifle. "Technologies of interest may include: fin-stabilized projectiles, spin-stabilized projectiles, internal and/or external aero-actuation control methods, projectile guidance technologies, tamper proofing, small stable power supplies, and advanced sighting, optical resolution and clarity technologies."

Exacto is one of several projects Darpa is developing to make snipers more accurate and more deadly. The agency has earmarked $7.5 million for a laser-guided bullet program. Darpa gave Lockheed $2 million for advanced sniper scopes that could boost kill rates by tenfold, or more. If the system works out as planned, it would actually allow snipers to remain virtually invisible, lost in the "heat haze" in between them and their targets. Our own David Hambling called the project the "next war's secret weapon."

From the MIT Tech Blog- Fixing the Economy with Green Jobs

Fixing the Economy with Green Jobs

A new report suggests that investing in clean energy could put people to work and stimulate economic growth.
Wednesday, November 26, 2008
By Kevin Bullis

President Elect Barack Obama recently called for stimulating the economy in part by direct government investment in clean energy, specifically in projects "building wind farms and solar panels." Through various "green" policies and investment he hopes to create 5 million new jobs.

A new report from Deutsche Bank supports this approach. It argues that it's possible to address challenges related to climate change, energy security and the financial crisis at the same time by investing in four specific areas: energy efficient buildings, electric power grid, renewable power and public transportation. The report cites figures that suggest investing in these areas creates more jobs than investing in conventional energy sources because much of the old energy infrastructure is already in place. It says that "a $100 billion investment in energy and efficiency would result in 2 million new jobs, whereas a similar investment in old energy [such as coal or natural gas] would only create around 540,000 jobs."

What's more, the report continues, when the government invests in a project, other investors line-up to invest as well. It "unlocks" private sector funding and partnerships.

Detractors say that clean energy can have a negative effect on jobs, since it tends to cost more. If energy costs are high enough, it could force companies to cut jobs.

Improving Pre Natal Testing


Color coding: Microarrays like the one above are used to test for chromosomal abnormalities. Each spot represents a different DNA segment. If the fetus has an extra copy of a particular segment of DNA, then the corresponding dot is red. If the fetus is missing a DNA segment, the dot appears green. The color yellow indicates that the fetus has the correct number of copies of the DNA segment.

Many pregnant women have their unborn children screened for genetic abnormalities, such as Down syndrome. But standard tests cannot identify all problems, and many extremely serious conditions go undetected until birth. In a new study, researchers from the Baylor College of Medicine in Houston used DNA chips to test unborn babies for more than 270 genetic syndromes. They found that this procedure provided a more detailed and accurate view of the fetus's genetic profile than the approach commonly used today.

The process normally used for prenatal diagnosis is karyotyping, which looks at the overall size and shape of chromosomes to identify problems. Sau Wai Cheung, director of Baylor's Cytogenetics Laboratory and one of the leaders of the new study, says the new research shows that DNA chips can reliably detect far smaller chromosomal abnormalities than karyotyping allows. And while these abnormalities may be small in size, they can have a big impact. "A lot of the diseases that we tested for [in this study] cause mental delays and problems with physical development," said Cheung. Angelman syndrome, for example, can result in significant developmental problems and seizures.

Arthur Beaudet, who led the study with Cheung and is chair of Baylor's Department of Molecular and Human Genetics, says some parents want an early diagnosis so they can decide whether or not to terminate a pregnancy. Others simply want the information to prepare for their child's special needs.

The DNA chip used in the study performs a process known as array comparative genomic hybridization (aCGH), which involves looking for an abnormal number of copies of particular segments of DNA. Normally, humans have two copies of each segment. Having extra or missing copies can result in serious medical problems. Each DNA chip contains hundreds of single-stranded DNA segments, each embedded in a piece of glass at a precise location. The researchers then add single-stranded, fetal DNA segments, usually taken from amniotic fluid. These strands are labeled red. Single-stranded DNA reference segments, which act as a control group and are labeled green, are also added to the chip. Once the fetal and control strands are bound with the embedded DNA, the arrangement of colors on the chip is imaged and analyzed by a computer.

"Basically we measured the color signal intensity," said Cheung. If the fetus has an extra copy of a particular segment of DNA, then the spot on the chip that corresponds to that DNA segment will appear more red than green. If the fetus is missing a DNA segment, the corresponding spot on the chip will appear more green than red. And if the fetus has the correct number of copies of the DNA segment, then the spot should appear yellow.

Beaudet says that aCGH is already used in pediatric medicine with great success, but it has only recently been investigated for prenatal diagnostics. While the Baylor study sample was small--only 300 cases--the researchers say it is the largest of its kind to date. In the study, published in the current issue of Prenatal Diagnosis, the researchers identified seven cases where the aCGH results provided new information about the risk of disease, including two cases that would otherwise have been missed.

"In general, it's a great study," said Dr. David Chitayat, head of the Prenatal Diagnostic and Medical Genetics Program at Mount Sinai Hospital in Toronto, Canada. "But we need to expand it."

Most of the patients involved in the study sought out the testing because of advanced maternal age. Chitayat says he would like to see results for a wider array of patients. Chitayat was not involved in the Baylor study, but he's working on another research project involving aCGH for prenatal diagnosis, and he hopes to publish the results soon.

As with any prenatal diagnostic testing, aCGH brings with it a host of questions about how much information is too much.

"The downside of aCGH is you pick up these copy-number variants that may or may not have clinical significance, and in the worst case [the impact] may be unknown," says Diana Bianchi, professor of pediatrics, obstetrics, and gynecology at Tufts University School of Medicine and the editor in chief of Prenatal Diagnostics. Knowing that an unborn child has genetic abnormalities but not knowing how those might affect the child's development could leave many parents scared and confused, Bianchi says.

Price is another factor that could impede the use of aCGH. Beaudet says that an array currently costs $1,600. That's far more than a karyotype, which costs between $500 and $700. (The tests reported in the study were performed on a fee-for-service basis.) But Beaudet believes the price of an array could drop significantly if the volume of tests performed increases.

Currently, karyotyping and aCGH also require invasive procedures--either extracting amniotic fluid or going into placental tissue--to retrieve samples for testing, and miscarriage can result. "The next big breakthrough would be to be able to [test] a maternal blood sample or a maternal Pap smear," says Beaudet, so that the baby wouldn't be put at risk. Several research teams are currently working on techniques for isolating fetal cells that float around in a pregnant woman's bloodstream.

Making an Old Brain Young


Credit: Phaedra Wilkinson

New ways to manipulate neural plasticity--the brain's ability to rewire itself--could make adult brains as facile as young ones, at least in part. Drugs that target these mechanisms might eventually help treat neurological disorders as diverse as Alzheimer's, stroke, schizophrenia, and autism. But first scientists will need to figure out how to harness this rewiring capacity without damaging vital neural circuitry.

"Once we understand the mechanisms behind plasticity, we can design therapies to tap into it more specifically," says Joshua Sanes, a neuroscientist at Harvard Medical School.

The brain experiences a "critical period" of heightened malleability during development, when outside experiences--such as sights and sounds--are necessary for different brain systems to develop normally. Infants and toddlers between the ages of one and three need regular visual stimuli, for example, in order for their visual systems to form the appropriate neural circuits. If one eye is impaired during this time, such as with lazy eye (also called amblyopia), vision may be permanently faulty.

Studying the equivalent of lazy eye in rodents, Takao Hensch and his colleagues at Children's Hospital Boston discovered two mechanisms that control this critical period. While some drugs were already known to accelerate the onset of this critical period--for example, valium, an anxiety drug that targets the brain's inhibitory signaling system--Hensch's work helps explain why and provides specific targets for new treatments.

Like children, rodents with one eye covered during their critical period never recover normal sight. Scientists use this fact to measure treatments that affect the timing of developmental neural plasticity. Treatments that extend the critical period, for example, allow adult animals reared with only one functioning eye to regain normal sight. Hensch's group has previously shown that a specific cell type, called a large basket cell, triggers the onset of neural plasticity. These cells are surrounded by molecular nets. "The critical period ends when the net wraps around [the cells] very tightly," says Hensch. So molecularly severing the nets with an enzyme called chondroitinase can restore plasticity in adults.

Hensch and his collaborators have now found that basket-cell development is controlled by a protein called Otx2. Overexpressing this protein can trigger a critical period of plasticity, while removing Otx2 halts it. While the findings are specific to the visual system, Hensch notes that different sensory systems also possess basket cells, and those might function the same way.

A second mechanism for manipulating neural plasticity in adults is blocking inhibitory molecules that the nervous system produces to stop neural growth. "The nervous system is hostile to growing new axons [the long neural projections that connect cells], which is why recovery after spinal-cord injury is so challenging," says Hensch.

Myelin cells, which form an insulating layer around axons, secrete some of these inhibitory molecules. By experimenting with certain drugs that loosen myelin, Hensch and his collaborators found they could make the normally stable visual system of adult rodents become plastic again, allowing amblyopic rodents to recover. (However, the drug used in the study is toxic, making it unlikely to be a useful therapy.)

Given the usefulness of recapturing the neural facility of youth--the ability to quickly learn a new language, for example--it may seem odd that the brain would have evolved multiple mechanisms for preventing major rewiring in adults. But the capacity to easily overhaul neural circuits could have a downside, perhaps erasing memories. "You might lose the identity you've built," says Hensch. "We want you to be able to keep what you know."

To successfully co-opt the plasticity of youth, scientists will likely need to target treatments very precisely. "Maybe we can do a careful release of the critical period," says Alison Doupe, a neuroscientist at the University of California, San Francisco, who was not involved in Hensch's research. For example, "maybe you could turn on [plasticity] only when learning Russian."

In addition to suggesting ways to enhance mental agility in old age, the findings may provide a new explanation for developmental disorders, such as autism.

Scientists have recently discovered that several strains of mice genetically engineered to mimic rare inherited forms of autism have an imbalance in levels of excitatory and inhibitory neural signals. Hensch's previous research suggests that this kind of imbalance can throw the critical period out of whack. "Maybe different brain regions become plastic too early or too late [in autism]," says Hensch. That might also explain why disruptions to such different molecules can trigger similar symptoms, he says. "Maybe they have a common wiring problem."

The researchers are now studying these imbalances in greater detail. For example, they found that mice from one of the strains, genetically engineered to show symptoms of autism, have too many neural connections in a specific part of the brain, although each connection is individually weak. "That could lead to too much variability," says Hensch. "Maybe we can use that property to repair the circuit."

The Anatomy of a Marshmallow

Just-Poured Marshmallows: Aki Kamozawa and H. Alexander Talbot

Most American children are familiar with marshmallows. These fluffy, chewy treats are sold in bags in the supermarket, often for use in Rice Krispie treats and s'mores. Marshmallow Fluff is a spreadable marshmallow product, often found nestled on shelves beside the peanut butter used for lunchbox confections, adding a sweet, viscous layer to sandwiches and brownies. Around Easter, marshmallow Peeps, with their softer structure and crunchy sugar coating, appear in stores. In many homes around the country, marshmallow-covered sweet potatoes are a staple at the Thanksgiving table. So what better time to learn more about them, and perhaps make some yourself?

The original marshmallow was named for the inclusion of marshmallow root in the recipe. The roots and leaves of the marshmallow plant contain mucilage, a slimy-textured demulcent best known for its use as a homeopathic cough suppressant. Marshmallow root is considered to be soothing and mildly antimicrobial. It has long been used as an herbal treatment for minor digestive issues and skin irritations, although its use in the creation of its namesake confection has long since fallen by the wayside.

At their most basic, marshmallows are simply comprised of a sugar solution beaten together with a food gum, such as gelatin or xanthan gum. You can add egg whites for structure -- since they are able to hold large volumes of air, their addition allows for much lighter marshmallows -- and various colorings and flavorings for flair. Essentially though, marshmallows are made from sugar, water, and a food gum. A percentage of glucose or inverted sugar is needed for stabilization. This is beneficial because it attracts moisture and keeps the sucrose or table sugar used in the candy-making process from crystallizing. A basic form of glucose can be created at home by making a simple syrup, which is simply sugar and water boiled together. The addition of cream of tartar or citric acid will help stabilize the inverted sugars by discouraging the formation of sugar crystals. This effect can also be achieved with a small addition of corn syrup to the sugar syrup mixture. These ingredients are not strictly necessary though, simply an added assurance of success.

Once the sugar solution is created, it must be heated to the proper temperature. Marshmallows are made with sugar that is heated to a temperature of 116°C/241°F, otherwise known as the soft ball stage. We recommend using a thermometer to determine the temperature, for maximum safety and efficiency. Once the sugar has been heated to the proper temperature, it is beaten into the melted gelatin. This is a strong mechanical process that requires a mixer, preferably a standing mixture to achieve the proper texture. The beating incorporates air into the structure, creating small bubbles throughout, much like those seen in well-made bread. This structure is what gives the marshmallow its light, fluffy texture. In addition to creating structure, the amount of beating will control the moisture content of the finished marshmallow. Longer beating times will translate into a drier, more chewy marshmallow with a longer shelf life.

Once the sugar has been absorbed and the desired texture has been achieved, the marshmallows are poured into a mold and left to set. Before pouring the marshmallow, you need to generously coat the mold or tray with loose cornstarch. The starch will have a drying effect on the outer surface of the candy, allowing it to set more rapidly and dry on the outside so that it can be easily handled. The skin-like coating that forms on the outside of the confection helps increase its shelf life and usability.

Marshmallows are actually quite easy to make at home. The addition of powdered and liquid colors and flavorings allow cooks to create a dazzling display of these spongy delights. Powdered additions may be added to the gelatin while it is bloomed in hot water. Liquid additions are best added during the beating process.

Since recipes for sweet marshmallows are easily found in cookbooks and on the Internet, in honor of Thanksgiving we have included a recipe for the slightly more savory and spicy Szechuan Peppercorn Marshmallow.

Szechuan Salt: Aki Kamozawa and H. Alexander Talbot

Szechuan Peppercorn Marshmallows

15 grams silver leaf gelatin
3 grams salt
1.5 grams Szechuan peppercorns
100 grams apple cider
305 grams isomalt
135 grams liquid glucose
cornstarch for coating the marshmallows

Line an 8-by-8-inch pan with parchment paper and dust the bottom and side generously with powdered sugar. Have more powdered sugar available to dust the top of the marshmallows.

Cover the gelatin sheets with cold water and let them soak until softened. The amount of water used should be just enough to hydrate the gelatin.

Place the salt and the Szechuan peppercorns in a skillet. Turn the heat on medium and toast the peppercorns until they start to release a fragrant smoke. When the peppercorns are just beginning to smoke, remove the pan from the heat and pour the salt and peppercorns onto a plate to cool. When the salt and pepper have cooled, place them into a spice grinder and grind together to a fine powder. Sift the powder through a fine mesh strainer to remove any large particles.

Heat the apple cider to a simmer. Squeeze out the bloomed gelatin, add it to the hot cider, and stir to melt the gelatin. Weigh the spice mixture and sprinkle the spice blend over the cider-bloomed gelatin. Pour the gelatin mixture into the bowl of a standing mixer fitted with the whisk attachment.

Place the isomalt and glucose in a pot and place over a medium-high flame. Bring the mixture to a boil and lower the heat to medium. Using either a candy or a digital thermometer, cook the mixture until it reaches 116°C. When the glucose mixture reaches 116°C, remove it from the heat and carefully pour it into the gelatin mixture. Turn the mixer on low, slowly stirring the hot sugar syrup. When the sugar syrup cools to 100°C, increase the speed to medium high. Whip the mixture for ten minutes until the mixture grows in volume and takes on the appearance of whipped marshmallow topping. The marshmallow will cool significantly during the beating process.

Pour the marshmallow into the prepared pan, using a lightly greased silicone or heatproof rubber spatula to help get the marshmallow out of the bowl. Coat the top of the marshmallow heavily with cornstarch. Cover the pan lightly with plastic wrap and refrigerate for 3 hours or until completely cool. Turn the marshmallows out onto a cutting board generously dusted with cornstarch, and cut into individual pieces using a sharp knife or a pizza cutter. Dust the cut edges with cornstarch to absorb excess moisture and prevent sticking.

Young Sports Fans Embrace Science

Harnessing football fever to help kids learn

Linebacker Tedy Bruschi addresses a class at Patriot Place: The Hall at Patriot Place

The Boston sports fan has been spoiled rotten over the past decade. Now middle school students in Beantown are receiving similar treatment with a unique program that uses sports to teach science at Gillette Stadium, home of the New England Patriots.

The Hall at Patriot Place is a museum for all things Patriots. From Brady to Belichick, adoring fans both young and old can relive their recent and past success with a technically impressive display. In addition to helping to fund the Hall, Raytheon has teamed up with the Patriots to start the youth outreach program "Science of Sports," aimed at mentoring kids in the greater Boston area Boys and Girls Clubs.

At the heart of the outreach are visits being made by Raytheon employees to help inspire a sports-science fair with entries from the local area. The fair will be held at the hallowed grounds of Gillette, with winning teams receiving $1,000 scholarships.

"Raytheon is committed to instilling in students a lifelong passion for math, science, and technology, and our proud support of the 'Science of Sports' program is just one of the myriad ways in which we are doing this," said Kristin Hilf, vice president of public affairs for Raytheon. "It is critical to engage young minds now, during their formative years, to build within them the skills that will help them achieve greater success in school, their careers, and throughout their lives."

The hall itself has a series of high-tech exhibits worthy of their own recognition. A 45-foot panoramic projection screen plays an opening video while a geodesic dome houses an exhibit about the infamous snow game. Fans can also compare their vertical jump to that of their favorite player, go under the hood to review plays like an NFL official, and listen to their hero Tom Brady call plays from the huddle. Now if only one of those students can come up with a fix for that darn ACL.

Living Large on Smaller Budget


Luxury is a malleable concept. After all, the details that impressed back in the Seventies and Eighties—tufted leather seats, digital dashboards, vinyl roofs, and opera windows—have become ironic jokes. But two aspects of luxury never go out of style: quality and performance. And in a worldwide economy that’s stutter-stepping around the abyss of a recession, it’s possible to get both for a low price. Ridiculously low.

The trick for those lucky enough to be prosperous in perilous times is to find products that fulfill their appetites without rubbing it in the unwashed faces of the downtrodden hoi polloi. Showing up for dinner at Ruth’s Chris in a block-long luxury flagship may have been the dream way back in 2007, but right now the smart money is staying with the premium brands, but going mid-size and ordering the New York strip at Outback. As to big V-8s, forget ‘em. No one with half a brain believes the current drop in oil prices will last, and today’s sixes are plenty good anyhow. There are bargains to be had. For you surviving plutocrats out there, here are five of the best.


2009 BMW 535i

The new-in-2008 BMW 535i is simply the best six-cylinder 5-series ever built and yes, that includes a couple of M5s. And all that goodness is directly attributable to the 300-hp, twin-turbocharged, direct-injected, 3.0-liter inline six under the 535i’s hood.

Of course this is the same turbo six used in the smaller 335i sedan, and it pulls from just off idle to redline with such luscious and velvety smoothness that it could have been engineered by NestlĂ©. It’s also wicked quick, ripping to 60 mph in just 5.4 seconds when this magazine tested an automatic, all-wheel-drive 535xi. There’s no reason to think that a rear-driven 535i wouldn’t easily match the 360-hp, V-8–powered 550i’s 5.2-second blitz from 0 to 60, even given less traction at launch.

Now here’s the kicker: The 535i’s $51,625 base price is a staggering $9200 cheaper than the 550i’s—and the 550i doesn’t include much more standard equipment. Meanwhile, the EPA rates the six’s fuel mileage at 17 mpg in the city and an excellent 26 on the highway. This one’s on the short list for world’s best overall car.

2009 Hyundai Genesis

Drive the new Hyundai Genesis while blindfolded—go ahead, the first 30 feet are fun—and you’d swear it was a new Lexus you’d just run into that telephone pole. The eerie silence, the slightly numb steering, the floating-on-cash suspension movements, all seem to have been lifted straight from Lexus’s Big Book of Disengaged Driving Sensations. Remove the blindfold and the Genesis kind of looks like a Lexus, too. Take a whiff and it. . . okay, it smells like a Hyundai.

But once past that olfactory disappointment, the Genesis is impressive in a staggering number of ways. However, the way it’s most impressive is price. Although it’s only 2.1 inches shorter than a Lexus LS460, the rear-drive, 290-hp, 3.8-liter V-6–powered Genesis’s base price of $33,300 is actually $2145 cheaper than that of Lexus’s front-drive ES350. Opt for the 368-hp, 4.6-liter V-8 in the Genesis, and you’ll surpass the Lexus by less than $3000. If you’re buying your next luxury car on a dollar-per-square-inch basis, you’ll want to shop Hyundai.

Of course, Hyundai’s complete lack of prestige may hinder some buyers. But others may think that only makes the car more attractive.

2009 Infiniti M35

The Infiniti M35 is a car for connoisseurs; an assembly of finely tuned parts that delivers a sublime driving experience without any flashy spoilers, wings, or decorative tape. It’s not the sort of car that impresses everybody, but it does impress the right somebodies.

Built around Nissan’s FM architecture that puts the engine behind the front axle line, the first advantage the M35 has over its V-8–powered M45 brother is a slightly lighter curb weight and slightly less of that weight over the front wheels. That leads to a lighter steering feel, even if there isn’t much difference in the way the car sticks on a skidpad or caroms through slalom cones.

The M35’s second advantage is that it’s powered by a 3.5-liter version of Nissan’s justly famed VQ engine family, rated at 303 hp. The M45’s 4.5-liter V-8 offers only 23 more horses, and the M35’s powerplant never feels strained or compromised in any way, and boasts an eager personality missing in many other luxury V-6s.

But the big advantage here is price, with the 2009 M35 starting at $46,615 and going up only modestly when options like the “Sport” package are ordered—the M45 starts at $52,965. For people who know how well the 35 drives, that it does so at a keen price makes it just that much more impressive.

2009 Jaguar XF

Jaguar’s XF sedan is the first new Jaguar to look really “new” since the 1961 E-type. There’s nothing about this wedge-shaped car that harkens back to some mystical moment in Jag’s past, there are no sops to tradition in any of its lines, and while there’s still plenty of mouth-watering wood and aromatic leather inside, that goofball J-shifter is finally gone to be replaced by the volume knob off the boombox you had in college.

All XFs sold in America are powered by a 4.2-liter V-8 in either naturally aspirated 300-hp or supercharged 420-hp form. There’s no denying that the blower amps up the action, but the unforced induction is wholly adequate with its sporting nature supported by an excellent, paddle-shiftable six-speed automatic transmission. The suspension meanwhile is both expectedly supple in ride and surprisingly tenacious in corners.

Finally, skipping the blower saves a buyer between $14,500 and $8,500, depending on how the XF is ordered (base price is $49,975). You can buy a lot of books about Jaguar’s glorious past with $14,500.

2009 Mercedes-Benz GL320 BlueTec

The only politically correct Chevy Suburban around today is the one carrying Barack Obama’s security detail. Otherwise, full-size SUVs are largely vehicular lepers. Except, of course, for Mercedes-Benz’s excellent GL320 BlueTec, which combines the utility of a Cadillac Escalade with the restrained luxury of Mercedes and an easygoing 3.0-liter V-6 turbo-diesel engine.

The all-wheel-drive GL320 is huge and, at first glance, the 210-hp turbo-diesel doesn’t seem like much to haul around its nearly 5600 pounds. But that engine produces an outstanding 398 lb-ft of torque and Mercedes’s seven-speed automatic transmission does a superlative job of keeping the engine in the meat of its power band. And the EPA-rated 17 mpg in the city and 23 on the highway is astonishing for a beast this big. Sure, it’s not cheap to buy, with a $59,075 base price, but at least it should be relatively cheap to operate.

How well does it drive? We clocked 0-to-60 time of 8.6 seconds in our long-term 2008 GL320, which isn’t bad. And it’s good enough for a GL320 to be newly crowned F1 World Champion Lewis Hamilton’s daily driver.

2010 Audi TTRS- Update


Five-cylinder engines have long been an Audi trademark. First used in 1977 in the Audi 100/5000, five-cylinders took Audi upmarket and clearly differentiated the brand from the competition. The Audi 200 Turbo, with its 170-hp inline-five, became the world's fastest four-door in 1984; the 315-hp, Audi 80–based RS2 Avant of the mid-‘90s was the most extreme station wagon of its time; and Audi won several rally championships with the five-banger Quattro—the S1 Pikes Peak had almost 600 hp.

In the mid-‘90s, Audi dropped the five-cylinder engine and its characteristic, subdued growl in favor of more conventional four-cylinder and V-6 engines. Brand aficionados howled in futile protest, and engineering guru Ferdinand PiĂ«ch, who had developed the five-cylinder engine but later moved on to become head of VW, said he never quite understood why the engine had been dropped.

It’s Back!

As of March 2009, a five-cylinder will be back in Audi's range in the form of a 2.5-liter unit with direct injection; it is based on Audi's modular engine architecture. The transversely mounted engine is force-fed by a single turbocharger and will make 330–340 hp. Torque is rumored to be around 330 lb-ft. That's enough to significantly set the TT RS apart from the lesser TTS with its 265-hp, 2.0-liter TFSI four-cylinder engine.

The TTS coupe is claimed to run from 0 to 60 mph in 4.9 seconds, and the fixed-roof TT RS—which will be built as either a 2+2 coupe or roadster—should jet to 60 at least a half a second quicker. If customers request it, top speed will be raised to 174 mph; the TTS is governed to 155. Curb weight will be around 3000 lb and Quattro all-wheel drive will be standard. Power will be transmitted through a six-speed manual transmission; it is unlikely that the dual-clutch transmission will be adapted to the TT RS.

Expect minor but significant changes to set the TT RS apart from the TTS. It needs even more air, so the front intakes will be larger, and it will sport the two large oval exhaust tips which identify Audi's RS models.

Headed For a Geneva Debut

Just a few months back, a tussle strained Audi and Porsche's high-tension relationship even further: Porsche threatened to take legal action against Audi's use of the RS moniker. Porsche had long ago managed to protect the RS nameplate for its exclusive use and allowed Audi to use it only in conjunction with a number, as on the RS 4, RS 6, and so on. Audi engineers went ballistic, and Porsche backpedaled, allowing the TT RS to keep its name. Listen for a five-cylinder rumble at the 2009 Geneva auto show next March, which is where the TT RS is scheduled to make its first public appearance.

The American M5- Pontiac G8 GXP

2009 Pontiac G8 GXP Front Three Quarters View

Strafing along a straight-as-a-string highway at about a buck-fifty, confusion struck. Were we in America aboard Pontiac's forty-or-so-grand, Pontiac G8 GXP circa 2008, or flogging a previous-generation BMW M5-a car that cost $70,000 eight years ago-on a German autobahn? Not sure. There's plenty of high-speed stability here, yet nice ride quality. A rumbling 400-plus-horsepower V-8 engine and six-speed manual transmission. Just-right-size four-door packaging, supportive leather sport seats, big brakes. Then the radio news guy said "Obama," and we realized that this was indeed the here and now. The badge on the steering wheel confirmed it. Mention BMW's seminal sport sedan and a Pontiac in the same breath? In this instance, without hesitation.

By now, you know the G8 is based on GM global rear-drive-chassis architecture born and bred in Australia. The base V-6 and 361-horse V-8 GT versions are currently on sale and playing to solid reviews. No, the G8 wasn't designed or built in Michigan, but that doesn't mean it's not a Pontiac. The car business continues to globalize, and variations on this theme are sold as Holdens, Daewoos, Opels, Vauxhalls-even Buicks in China and Chevys in the Middle East, so get over it.

Under the hood of the GXP version rests as American a powerplant as was ever born, the latest and (nearly) greatest version of the Small Block Chevy, now called the LS3. At 6.2 liters, it grunts out 415 horsepower and the same amount of torque. Why "nearly" the greatest? Only the ZR1 and Cadillac CTS-v's supercharged version could be any greater. While the G8 GT is served only with a six-speed automatic transmission, clutch-and-shifter types can opt for a six-speed manual. We tested both and found their accelerative performance nearly identical, favoring the stick by never more than a tenth or two. And the GXP does its thing on regular-grade fuel, although it will earn a gas-guzzler tax (final pricing was not confirmed as of this writing).

The GXP designation signifies more than an engine upgrade. With more go comes more stop, in the form of Brembo brake calipers, clamping 14.0-inch rotors front and 12.8-inchers aft. The G8 GT's suspension is already competent, but is retuned for GXP duty; the biggest change is larger front and rear anti-roll bars. The shocks are stiffer, and the rear balljoints are revised. Nineteen-inch alloy wheels are standard, as is summer-rated performance rubber (all season tires are also available). Calibration of the power rack-and-pinion steering is unchanged.

Styling cues are modest: The front and rear fascias are GXP-specific. There's too much fakery here for our taste: fake hood scoops, fake diffuser treatment in back, non-functional gills on the front fenders. But Pontiac isn't the only one to play that game. A matte-black or body-color side window surround would add back some stealth, but overall, the G8 GXP is a great-looking piece, with strong shoulders, a brand-proper face, and muscular stance.

Inside you'll find thickly bolstered sport seats that really hold you in place. Rubber-trimmed alloy pedals look good and grip your Pilotis, but the beefy GXP steering wheel is a disappointment. It's square on the bottom and has cutouts for your thumbs, trying to emulate the tillers on banzai runners like the C63 AMG and BWM M3. But the lumps and bumps are all in the wrong place, creating more discomfort than benefit. The engine maxes out at 6600 revs, but you wouldn't know it from the redline-less tach that's marked to 8000.

Want more M5 references? The Pontiac is an inch and a pound larger in every direction, but nips the BMW in most performance categories. The previous-gen M5 ran 0-to-60 in 4.5 seconds; the trans G8 GXPs match that. The Bimmer grips to 0.84 g on the skidpad, the Pontiacs stick to 0.88-0.90 g. The BMW stops from 60-0 in 116 feet, the Pontiacs from 111-117. This is all the more impressive given the M5's near 200-pound weight advantage. Sure, the premium German performance kings have moved on from that previous-gen M5, but look what they cost. Before we forget, the LS3 sounds magnificent too; deep at idle, all pops and burbles on the overrun, yet never over the top.

As noted, we sampled both transmission offerings and find each appealing for different drivers. The manual's short, meaty stick has a crisp, direct shift linkage, although several staffers feel the clutch takeup is light and lacking engagement feel. The gear ratios are spot on. On many cars, GM cranks in an overly aggressive throttle tip-in curve that gives the impression of super-quick response, fading to nothing as the pedal goes further to the floor. In this application, it feels unnatural and jerky. The G8 GXP is legit fast -- why fake it?

The automatic offers standard Drive, Sport Drive, and Manual modes. Drive is responsive yet smooth; ideal for normal running. Sport shifts quicker, holds gears longer, and downshifts sooner. Kudos for GM delivering a true manual mode, too. Click the shifter to the manual gate, and it'll hold gears right to the rev limiter without upshifting. And it won't downshift however hard you mash the gas. It's too bad that manual gate is on the far side of the console on left-hand-drive cars. Shifter paddles would have been fun too.

There's no griping about the G8 GXP's ride and handling balance. In spite of some musclecar DNA, there's worldly breeding here. This machine is quiet at speed, with a minimum of wind noise or road rumble. The steering's weight, feel, and response are satisfying. The chassis tells you what's going on, and when the high limits are nearing. Weight distribution is a well-balanced 52 front, 48 rear. And it all comes in a package you can live with. Rear leg/headroom is excellent, even for tall occupants. The 17.5 cubic feet of trunk space is flat and useable. The audio and infotainment packages are acceptable, if not class leading, and we'd take a good touch-screen nav over OnStar's turn-by-turn directional guidance any day.

Pontiac's maximum strength G8 is a few details shy of legend, but that doesn't diminish its huge appeal and sophisticated, capable performance. The G8 GXP is a terrific, all-around sport sedan that runs with high-priced Germans. Its strong value message isn't a qualifier either, just a bonus. You could also think of the G8 GXP as a four-door Corvette of sorts. No matter, it is the best-performing, most well-balanced production Pontiac ever. That tells you all you need to know.

Hussman Funds Weekly Market Comment-

Wheat from the Chaff

Red Monday on Wall St

NEW YORK (CNNMoney.com) -- The new month got off to a dismal start as stocks tumbled Monday morning on dismal manufacturing reports added to fears of a prolonged recession.

The Dow Jones industrial average (INDU) lost 380 points - or more than 4% - an hour into the session. The Standard & Poor's 500 (SPX) index lost 5% and the Nasdaq composite (COMP) gave up 4.7%.

Stocks gained in a holiday-shortened trading week after President-elect Obama announced his economic team and the government bailed out Citigroup. The Dow and S&P 500 rose Friday for the fifth consecutive session, the best streak since July 2007

Positive reports on Black Friday, the start of the critical holiday-shopping period, also helped stocks late last week. But the advance petered out Monday as investors eyed the day's economic news and worried that the Black Friday momentum was unsustainable.

Economy: The morning economic news was dismal, demonstrating that a recession is indeed underway even if it hasn't been officially declared.

The Institute of Supply Management said its November manufacturing index fell to a 26-year low of 36.2 from 38.9 in October. That was worse than what economists were expecting, according to a survey from Briefing.com.

October construction spending fell 1.2% versus a flat reading in the previous month. Economists thought spending would drop 1%.

Global economic news was pretty grim as well, with manufacturing surveys in Britain and the euro zone showing a steep slowdown. A reading on China's manufacturing survey was equally worrisome.

Asian markets ended in mixed territory and European markets tumbled in the afternoon.

Retail sales: Shoppers came out in droves over the weekend, motivated by pent-up demand and deep discounts, but the surge is not expected to last.

Including "Black Friday," the day after Thanksgiving, shoppers spent $41 billion in the four-day holiday weekend, according to the National Retail Federation (NRF), an industry trade group. The average shopper spent $372.57, up 7.2% from a year ago.

However, overall 2008 holiday spending is expected to rise just 2.2% from a year ago, the smallest gain in six years.

Early predictions are for "Cyber Monday" online shopping sales to be pretty flat with a year ago.

Consumer spending drives two-thirds of economic growth, and the pull back has exacerbated the economic slowdown.

Automakers: GM (GM, Fortune 500) and Ford (F, Fortune 500) gained on growing bets that they, along with Chrysler, will receive a government bailout. The industry's first pitch to Congress was rebuffed, but there is increased speculation that its second pitch will be more successful.

The companies have until Tuesday to submit proposals for how they would use $25 billion in taxpayer money to make their companies "viable." The House Financial Services Committee is holding a hearing Friday; the Senate Banking Committee is expected to host a hearing this week, too.

Other movers: Johnson & Johnson (JNJ, Fortune 500) said it will buy breast implant maker Mentor (MNT) for $1.07 billion, or $31 a share, nearly double the company's closing price from Friday. Dow stock J&J fell 2%, while Mentor gained 90%.

Other markets: The dollar gained versus the euro but fell against the yen.

U.S. light crude oil for January delivery fell $3.88 to $50.55 a barrel on the New York Mercantile Exchange.

COMEX gold for February delivery fell $9.20 to $811.30 an ounce.

Gasoline prices continued the fall to nearly four-year lows, with gas down 1.7 cents to a national average of $1.868 a gallon, according to a survey of credit-card swipes released Wednesday by motorist group AAA. Prices have been sliding for more than two months, losing almost $2 a gallon or 51%. To top of page

C/D 370Z Review



*We once heard William F. Buckley Jr. say that, and it sounded cool.

At the Z car’s U.S. introduction 40 years ago, Datsun wisely chose not to employ its domestic “Fairlady” moniker, which Yutaka Katayama knew would have been tantamount to calling, say, the Corvette the “Cocker Spaniel.” Since then, the hyphen that originally separated the “240” from the “Z” has vanished, 1.3 extra liters of displacement have more than doubled the original engine’s output, an actor briefly made Mr. K a red-bespectacled TV star, and the car’s price has swollen by about $27,000.

Nissan refers to this latest Z as an “enhancement,” likely largely a male enhancement, rather than a whole new car. The company is being modest. The wheelbase is shorter by 3.9 inches, width is up 1.1 inches, length is down 2.7 inches. The larger engine (same V-6 as in the Infiniti G37) produces 332 horsepower, a bonus of 26, and it sits 15 millimeters closer to the pavement, which is now hugged by a true unequal-length control-arm front suspension. Although Nissan’s engineers had to add nearly 200 pounds of safety and regulatory bric-a-brac, the car is only 33 pounds heavier than the 350Z we tested in June of ’07, in part because the hatch, A-pillars, and doors are now aluminum. We know, because we attacked them with a “Big Sky” fridge magnet.

Two models are on offer: the base car, starting at $30,625, and a Touring version, which leans toward luxury—leather, Bose stereo, so forth. In either case, options are few: a nav system, a seven-speed automatic, and a Sport package. The latter, as fitted to our test car, includes a limited-slip diff, 19-inch wheels, spoilers, larger brake rotors and aluminum calipers, and “SynchroRev Match” for the six-speed manual.

Every body panel is fresh, and the styling, penned in San Diego, is largely successful, although it ignited some vivid office discussion. First, the dual shark’s teeth in the grille look like the outcome of a dolorous ninth-grade study-hall class. The oversize chrome door handles, which we’d paint flat black or body color, would look more at home on a Nissan Armada. And the roof so steeply cants downward that its leading edge forms a sharp, hard crease we’re calling the “Alfalfa peak”—an odd ridge on a car that is otherwise a lava-lamp jubilee of rounded Oprah-ness. Nissan says the roof is intended to look like the GT-R’s. We ask, “Is that important?” A convertible 370Z will arrive as a 2010 model.

The cockpit is richer than its predecessor’s, with graceful contrasting stitching, a kneepad on the center console, and a classy hinged leather panel covering the hole you’ll create if you don’t order the nav system. There’s now even a glove box. The accelerator pedal is floor mounted, and its travel feels freer and more linear. The steering wheel is asymmetrical, neither circular nor oval, but its size and grip are perfect. Although the wheel is adjustable for rake alone, the entire IP moves along for the ride, assuring a clear shot at the gauges. The driver’s seat is more aggressively bolstered than the passenger’s, and both are upholstered in nonslip fabric. They’re a tight fit, with the more globularly hipped among us contemplating the possibility of embarrassing chafing. The size of the shift knob, the pedals’ placement, the three big HVAC controls—all represent an ergonomic hat trick. What’s more, the monstrous cross support aft of the seats, which nearly bifurcated the cargo area, is now replaced by a simple aluminum tube that does minimal damage to storage space.

At the track, the 370Z easily outpaced its predecessor: 0.3 second quicker to 60 mph, a half-second quicker to 100. The 370Z accelerates to 60 mph a mere 10th behind a Porsche Cayman S. The new Z’s 30-to-50 passing potential is now about a second better, and it picked up 0.9 second in its 50-to-70-mph burst. Skidpad grip has risen from 0.93 g to a tendon-bending 0.97 g, and the new brakes (no longer Brembos but Akebonos) have tightened stopping distance to 159 feet—race-car territory, kids.

On the highway and in traffic, the 370Z is one Z-licious companion. From rest, the car rolls away elegantly, asking for a mere handful of revs above idle. Clutch takeup is predictable, and the shifter’s throws are so short and smooth that your forearm barely moves. Power manifests as low as 1900 rpm and flows in one great, seamless rush to redline, with no discernible variable-valve step. Brake-pedal travel is minimal, taut, linear. And the structure feels as solid as a Porsche 911’s, issuing exactly zero rattles or squeaks.

The steering is a little heavy but is always accurate, quick, yet never nervous. Aim for a pebble at an apex, and you can place the inside front tire atop it. Select a path through a sweeper, and no further corrections are required. Over scabrous pavement, the 370Z tracks better than its predecessor, and it has a locomotive’s sense of straight-ahead. Brain-damaged text messagers will be in heaven—that’s how long you can take your hands off the wheel.

Body motions are virtually nonexistent, and the ride can be borderline harsh, but both traits remain appropriate to a dedicated sports car. In the hills, the 370Z is simply BMW-ish in the manner its engine and transmission talk to each other. Jump in or out of the throttle, and there’s no jolt, no windup, no neck snap. Revs build and dissipate rapidly but without notice. The car eagerly establishes a soothing driving rhythm, such that glancing at the speedometer always produces a shock. When did we get going this fast? That’s a sure-fire sign of sedulous engineering.

Up to about eight-tenths on the Blow-Your-Lunch meter, the Z is remarkably neutral. On low-friction surfaces, however, you can deactivate the stability control and induce shooting chest pains courtesy of big throttle-induced oversteer. What’s just as fun and less stressful is to apply 100 percent power out of every corner and let the stability control sort things out.

Speaking of miraculous driving aids, here’s one we weren’t expecting. If you order the Sport package, the manual trans is fitted with the aforementioned SynchroRev Match, which blips the throttle during downshifts. We did some patent searches and believe this electronic boon to be a first on a wholly manual transmission. Upon hearing about it, we warned Nissan that our old-fashioned heel-and-toeing was pure Nureyev—no electronic wet nurses for us. We were wrong. Our own dance steps matched revs accurately about 80 percent of the time. Nissan’s electronic shoes matched revs 100 percent of the time. And you can’t fool the thing. A downshift from fifth to second that requires 4500 immediate revs? No problem. That tricky 10-mph downshift from second to first on a cold morning? Piece of cake. Enter a turn so fast that your whole focus is on braking and steering? Let Nissan manage the blipping. If you still think you can do better, you can deactivate it. But those creamy downshifts add so greatly to the car’s prescient interaction with the driver that we bet you won’t.

Our complaints are few. Visibility astern is slim through that gun slit of a backlight—now sans wiper—and the rear-three-quarter windows don’t even qualify as portholes. The V-6’s exhaust note, at least inside the cockpit, isn’t much sexier than a Pathfinder’s. The gas gauge comprises 16 orange LEDs that are hard to read and look like a temporary fix conjured by the doofus who forgot to order the real gauge. Finally—and this is the big one—the sticky Bridgestones double as megaphones. Boom, slap, echo, hiss, the swishing of water, the pinging of pebbles. You name a road-borne sound, and the tires can magnify it. Perhaps it’s the fault of paper-thin wheel-well liners, because neither engine nor driveline NVH find their way so effortlessly to your tympanic membranes. At idle and at wide-open throttle, the 370Z is louder than its forebear. We’d trade a couple of points on the skidpad in return for less racket and a slightly cushier ride.

Do we love the 370Z? It might now be instructive for the reader to review the text and take a census of superlatives. This latest Z offers amenities sufficient to satisfy a commuter, without doing any obvious harm to the car’s original charm—its bare-bones purity.

In the race among automakers to make in-car cell-phone calls and iPod twiddling ever easier, it’s refreshing to find an addition such as the 370Z’s rev-matching downshifting that actually enhances the driving experience. I must have shifted 500 times on the way home just to marvel at this clever tech tidbit I never knew I wanted. The 350Z was always a road-course missile, now complemented by a much-needed dose of refinement. With cars like the Z within reach, do adolescents still aspire to Mustangs?

MICHAEL AUSTIN

The 370Z is proof that revolutionary changes aren’t mandatory to keep a model line fresh. The 350Z lacked a decent interior and storage space, and its styling was starting to look dated. The new car addresses these shortcomings and improves what was already a good package. The result is one of the most desirable sports cars on the market. Steady progress in a model line is not a new idea—Porsche has been following it since, well, forever. Other automakers should take note of this success.
