U.S. Sets Up World's Largest Face Transplant Programme For Disfigured War Veterans

U.S. soldiers disfigured in combat will now be able to get face transplants

From The Daily Mail:

The world's biggest face transplant programme is being set up in Boston for veterans left severely deformed after surviving horrific war injuries in Iraq and Afghanistan.

The U.S. Department of Defence has given Brigham and Women’s Hospital in the city a $3.4million contract to pay for the first batch of operations.

It is hoped the Boston doctors will carry out face transplants on six to eight patients over the next 18 months - nearly doubling the nine known procedures completed worldwide.

From The Science Daily:

Science Daily (Dec. 22, 2009) — Evidence of sophisticated, human behavior has been discovered by Hebrew University of Jerusalem researchers as early as 750,000 years ago -- some half a million years earlier than has previously been estimated by archaeologists.

The discovery was made in the course of excavations at the prehistoric Gesher Benot Ya'aqov site, located along the Dead Sea rift in the southern Hula Valley of northern Israel, by a team from the Hebrew University Institute of Archaeology. Analysis of the spatial distribution of the findings there reveals a pattern of specific areas in which various activities were carried out.

Music Linked To Marijuana Use

From Live Science:

Teens who listen to music that mentions marijuana are significantly more likely to use the drug, a new study finds.

The research was based on surveys with 959 ninth-graders.

"Students who listen to music with the most references to marijuana are almost twice as likely to have used the drug than their peers whose musical tastes favor songs less focused on substance use," said University of Pittsburgh School of Medicine researcher Dr. Brian Primack, who led the study.

Platoon-Level 'Cloud' Lets Soldiers Swap Data, Increases 'Network Lethality'

Better Connectivity A unit-level "cloud" will allow soldiers in the field to communicate vertically up the chain of command, as well as with other ground and air units operating nearby for seamless sharing of intel, orders, and other data. U.S. Army

From Popular Science:

There's no question that the U.S. military is operating at a very high technological capacity, but the tactical edge that commanders have back at HQ doesn't always translate to grunts in the field. That gap is closing however, as the Army recently networked two distant infantry units together in a mobile "cloud," allowing them to trade video imagery, voice commands, text messages and other data between between them as they operated, as well as with far-flung command posts.

From New Scientist:

Fancy having your genome sequenced? It's becoming affordable, and 2010 will see the launch of a wave of genetic discovery that could turn it into a purchase worth making.

In the coming months, plummeting costs will allow gene hunters to start routinely working with complete human genome sequences. These should start to illuminate the "dark matter" of the genome - the as yet unknown genetic influences on our health that are missed by current scans.

Computers Offer A Faster Way To Cure Humanity's Ills

From The Guardian:

Scientific research and medical breakthroughs increasingly depend on huge computer power.

HOW DO YOU predict whether a given patient is likely to die from a heart attack? Conventional medical wisdom would base a risk assessment on factors such as the person's age, whether they were smokers and/or diabetic plus the results of cardiac ultrasound and various blood tests. It may be that a better predictor is a computer program that analyses the patient's electrocardiogram looking for subtle features within the data provided by the instrument.

From The Christian Science Monitor:

As stone tablets gave way the codex, the future of reading is digital – but will the e-reader and the e-book change the nature of how we read?

Jeremy Manore, an 18-year-old from central New Jersey, subscribes to several magazines and reads books constantly – John Steinbeck and F. Scott Fitzgerald are among his favorite writers. When he came home from his elite Massachusetts boarding school for Thanksgiving, Jeremy brought three books to read, his mother, Sandy Manore, says. But he wasn’t carting heavy volumes in a backpack.

Thinking Out Loud Helps Solve Problems

From The Telegraph:

Thinking out loud really does help you to solve problems faster, scientists have discovered.

People who talk out loud to think through their maths problems are able to solve them faster and have more chance of getting the right answer, the research has found.

In a finding that flies in the face of the old-fashioned theory of studying in silence, classrooms should be full of the noise of students tackling their problems out loud.

From The Independent:

It began life during the last ice age, long before man turned to agriculture and built the first cities in the fertile crescent of the Middle East. It was already thousands of years old when the Egyptians built their pyramids and the ancient Britons erected Stonehenge.

The Jurupa Oak tree first sprouted into life when much of the world was still covered in glaciers. It has stood on its windswept hillside in southern California for at least 13,000 years, making it the oldest known living organism, according to a study published today.

Mind-Reading Brain Implant Could Allow Paralysed To Turn Their Thoughts Into Instant Speech

The patient had a stroke in the brain, which stopped neural signals from travelling through the body. The electrode bypassed these channels and sent the thought signals to an FM receiver outside the body to a speech synthesizer via a neural decoder

From The Daily Mail:

A revolutionary new device that reads a person's thoughts and turns them into speech could soon change the lives of paralysed patients around the world.

The Neuralynx System is being developed by a team of scientists led by Professor Frank Guenther at Boston University.

Users will simply have to think of what they want to say and a voice synthesizer will translate the thoughts into speech almost immediately.

Supernova Remnants Reveal How The Star Exploded

Supernovas that come from thermonuclear explosion on white dwarfs (known as Type Ia) produce very symmetric remnants. Another type, created when a very massive star collapses, results in more asymmetrically shaped remnants. (Credit: NASA/CXC/UCSC/L. Lopez et al.)

From Science Daily:

Science Daily (Dec. 21, 2009) — At a very early age, children learn how to classify objects according to their shape. Now, new research suggests studying the shape of the aftermath of supernovas may allow astronomers to do the same.

A new study of images from NASA's Chandra X-ray Observatory on supernova remnants -- the debris from exploded stars -- shows that the symmetry of the remnants, or lack thereof, reveals how the star exploded. This is an important discovery because it shows that the remnants retain information about how the star exploded even though hundreds or thousands of years have passed.

From The Economist:

Consumer products and video-gaming technology are boosting the performance and reducing the price of military equipment.

VIDEO games have become increasingly realistic, especially those involving armed combat. America’s armed forces have even used video games as recruitment and training tools. But the desire to play games is not the reason why the United States Air Force recently issued a procurement request for 2,200 Sony PlayStation 3 (PS3) video-game consoles. It intends to link them up to build a supercomputer that will run Linux, a free, open-source operating system. It will be used for research, including the development of high-definition imaging systems for radar, and will cost around one-tenth as much as a conventional supercomputer. The air force has already built a smaller computer from a cluster of 336 PS3s.

Dogs Better Than Human Walking Companions

From Future Pundit:

No surprise here. Oh, and cats aren't getting you any exercise.

Is it better to walk a human or to walk a dog?

New research from the University of Missouri has found that people who walk dogs are more consistent about regular exercise and show more improvement in fitness than people who walk with a human companion. In a 12-week study of 54 older adults at an assisted living home, 35 people were assigned to a walking program for five days a week, while the remaining 19 served as a control group. Among the walkers, 23 selected a friend or spouse to serve as a regular walking partner along a trail laid out near the home. Another 12 participants took a bus daily to a local animal shelter where they were assigned a dog to walk.

From New Scientist:

In 1961, Yuri Gagarin became the first human being to reach outer space. Eight years later, Neil Armstrong and Buzz Aldrin made it to the surface of the moon. And that is as far as any of us has ventured.

Apart from the mundane problems of budgets and political will, the major roadblock is that our dominant space-flight technology – chemically fuelled rockets – just isn't up to the distances involved. We can send robot probes to the outer planets, but they take years to get there.

Europe's Mars Missions Get Final Go-Ahead

From The BBC:

Member-states of the European Space Agency (Esa) have given final approval to revised plans to explore Mars.

There have been protracted discussions on what Europe could do at the Red Planet and how much it might cost.

The Council of Esa has given the green light to a two-mission endeavour that would see the launch of an orbiter in 2016 and a rover in 2018.

The exploration projects will be undertaken in partnership with the US space agency (Nasa).

Nathan Myhrvold's Anti Global Warming Scheme

From Associated Content:

Nathan Myhrvold is a former technology officer for Microsoft who has found his own company, Intellectual Ventures, which is involved in a number of technology development programs, including new forms of energy generation.

Nathan Myhrvold also thinks that he has found a cheap and reliable way to solve global warming, which does not involve upending and perhaps destroying the world's economy. The global warming solution proposed by Nathan Myhvold involves Nathan Myhrvold's Anti Global Warming Scheme running a hose up to the stratosphere with balloons and using that hose to pump out enough sulfur particles to dim the sun's heat just enough to counteract the effects of global warming. The estimated cost would be about two hundred and fifty million dollars.

The Air Force's Next-Gen Bomber

The B-2 It's bad, but the brass wants something badder. The next-generation of bombers will conduct extensive intelligence, surveillance and reconnaissance missions, as well as carry directed-energy and other non-kinetic weapons.

Air Force's Next-Gen Bomber Will Be More Spy Plane Than Strike Aircraft -- Popular Science

It turns out the Air Force's next-gen bomber really isn't much of a bomber at all. While the next iteration of stealth bombers is still but a sketch on the drawing board, the DoD and top Air Force command know what the wars of the next century will call for: intelligence, surveillance, and reconnaissance (ISR), as well as the ability to deploy non-kinetic weapons to disrupt enemy operations, all while reserving the ability to drop the occasional ordinance -- and do it all at the same time with a single, stealthy super-weapon.
