Pioneering Stem Cell Treatment Restores Sight

From The Telegraph:

A man blinded in one eye by a chemical attack as he intervened to stop a fight has had his sight restored thanks to pioneering new stem cell treatment.

Russell Turnbull, 38, lost most of the vision in his right eye when he had ammonia sprayed into it as he tried to break up a fight on a late night bus journey home.

The attack, which badly burned and scarred his cornea, left him with permanent blurred sight and pain whenever he blinked.

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.

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.

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.

21 Things That Became Obsolete This Decade

Yellowstone's Plumbing Exposed

Image: Seismic imaging was used by University of Utah scientists to construct this 3-D picture of the Yellowstone hotspot plume of hot and molten rock that feeds the shallower magma chamber (not shown) beneath Yellowstone National Park, outlined in green at the surface, or top of the illustration. The Yellowstone caldera, or giant volcanic crater, is outlined in red. State boundaries are shown in black. The park, caldera and state boundaries also are projected to the bottom of the picture to better illustrate the plume's tilt. Researchers believe "blobs" of hot rock float off the top of the plume, then rise to recharge the magma chamber located 3.7 miles to 10 miles beneath the surface at Yellowstone. The illustration also shows a region of warm rock extending southwest from near the top of the plume. It represents the eastern Snake River Plain, where the Yellowstone hotspot triggered numerous cataclysmic caldera eruptions before the plume started feeding Yellowstone 2.05 million years ago.

From E! Science News:

The most detailed seismic images yet published of the plumbing that feeds the Yellowstone supervolcano shows a plume of hot and molten rock rising at an angle from the northwest at a depth of at least 410 miles, contradicting claims that there is no deep plume, only shallow hot rock moving like slowly boiling soup. A related University of Utah study used gravity measurements to indicate the banana-shaped magma chamber of hot and molten rock a few miles beneath Yellowstone is 20 percent larger than previously believed, so a future cataclysmic eruption could be even larger than thought.

Spitzer’s Cold Look At Space

From American Scientist:

To get a clear view of infrared emissions from celestial objects, the Spitzer Space Telescope has been cryogenically cooled—and what sights it has seen.

In astrophysical observations, more is more—imaging across multiple wavelengths leads to richer information. One electromagnetic band in which most celestial bodies radiate is the infrared: Objects ranging in location from the chilly fringes of our Solar System to the dust-enshrouded nuclei of distant galaxies radiate entirely or predominantly in this band. Thus, astrophysicists require good visualization of these wavelengths. The problem, however, is that Earth is a very hostile environment for infrared exploration of space, as the atmosphere also emits in the infrared spectrum and additionally absorbs much of the incoming signal. Even heat produced by a telescope itself can degrade its own clarity.

Sven Hagolani / Corbis

From Time Magazine:

One in 110 American children are considered to fall somewhere along the autism spectrum, according to the latest report released by the federal government. The new figure, which was released initially in October, comes from the most comprehensive set of data yet on the developmental health of eight-year-olds.

Increasing the previous federal estimate of 1 in 150, the new data suggest that 1% of children now exhibit some symptoms of an autism spectrum disorder (ASD), a collection of neurological conditions whose symptoms may range from mild social impairment to more serious communication, language and cognitive deficits. The estimate also represents a stunning 57% increase in prevalence since 2002, when health officials first began a nationwide effort to quantify the risk of autism in childhood.

Science magazine is reporting tonight that President Obama has made his decision about the future of the U.S. human space flight program, with a plan to turn over space taxi services to the International Space Station to commercial companies and to direct NASA to spend its money and resources developing a heavy-lift booster for human missions to the moon, asteroids and the moons of Mars.

Citing unnamed sources, the magazine reports that Obama will ask for a $1 billion boost in NASA’s 2011 budget to jumpstart the new launcher and to expand the agency's Earth-monitoring science satellites.

About Wikipedia’s Handling Of Controversial Topics…Like Climate Science

From Fabius Maximus:

Summary: This is a hat trick. About effective propaganda. And climate science. And more evidence that Wikipedia cannot be relied upon as an information source regarding controversial matters — or any work of importance. (It’s always useful as a first place to look and source of links.)

  1. Wikipedia Is A Stunning Example Of How The Propaganda Machine Works“, Lawrence Solomon, National Review (reposted by CBS), 8 July 2008

Update: an email reply by Wikipedia Editor Pierre Grés to Dennis Kuzara’s complaint about bias of Wikipedia Administrator William Connolley, posted at Watts Up With That, 19 December 2009 (see the actual Wikipedia file on this here):

“In September 2009, the Wikipedia Arbitration Committee revoked Mr. Connolley’s administrator status after finding that he misused his administrative privileges while involved in a dispute unrelated to climate warming.”

We’ll learn much about Wikipedia’s honesty by what happens now to the dozens of articles seriously distorted or outright suppressed by Connolley. Is this a structural problem with Wikipedia, or just a bad apple in the barrel?

Sophisticated New Computer Models Predict Details Of Insurgent Attacks

How Do The World's Most War-Torn Countries Always Seem To Have A Toyota Dealership?
Foreign Policy


From Popular Science:

Chaos, confusion, and uncertainty have pervaded battle since Homer first described the din of clashing hoplites. But new developments in computer modeling look to pierce the fog of modern war by predicting the time and location of insurgent attacks. More comprehensive than the SCARE IED cache location program, these models claim to have predicted everything from the number of casualties in an attack to the cease-fire between Israel and Hezbollah.
