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.

Engage The X Drive: Ten Ways To Traverse Deep Space

The VASIMR ion engine could - if powered by an onboard nuclear reactor - take astronauts to Mars in just 39 days (Illustration: Ad Astra Rocket Company)

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.

From Live Science:

Using snake-like fangs, saber-toothed dinosaur relatives of velociraptors likely subdued their prey with venom, scientists now suggest.

Paleontologists analyzed the skulls of Sinornithosaurus, whose name means "Chinese bird lizard." This narrow-snouted raptor was the fifth and most bird-like dinosaur species ever to be discovered, and lived roughly 125 million years ago in the warm, moist forests of northeastern China during the late Cretaceous.

Inflated Expectations: Crowd-Sourcing Comes of Age in the DARPA Network Challenge -- Scientific American

The M.I.T. and Georgia Tech teams proved most successful in using social networks to pinpoint the locations of 10 red weather balloons scattered throughout the U.S.

The U.S. Defense Advanced Research Projects Agency's (DARPA) Network Challenge earlier this month demonstrated that social networks, more than being platforms for self-promotion, can be also be highly effective tools for rapidly gathering and disseminating very precise information. With the help of Facebook, Twitter and a homemade Web site, a winning team from the Massachusetts Institute of Technology (M.I.T.) was able to within nine hours identify the correct latitude and longitude of all 10 of DARPA's red weather balloons, which were lofted 30.5 meters into the air at locations scattered throughout the U.S.
