From Science Daily:

Science Daily (Jan. 28, 2010) — Psychologists at the University of Pennsylvania and the University of Memphis have released a new study on linguistic evolution that challenges the prominent hypothesis for why languages differ throughout the world.

The study argues that human languages may adapt more like biological organisms than previously thought and that the more common and popular the language, the simpler its construction to facilitate its survival.

New Tyrannosaur Species Discovered

Scientists have describe a new dinosaur species, Bistahieversor sealeyi, which belongs to the same lineage as Tyrannosaurus Rex. Here, an image of the adult fossil skull. The animal had a deep snout (as seen vertically from the side), like T. rex, but many subtle distinguishing features set it apart as a new species.

From Live Science:

T. rex's family tree just got one member larger. Scientists unearthed bones from a new dinosaur species, including an adult specimen and bones from a "teenager" that lived some 75 million years ago.

Called Bistahieversor sealeyi, the dinosaur lived about 10 million years before Tyrannosaurus rex appeared on the scene. Even so, B. sealeyi belongs to the same dinosaur linage as the famous T. rex.

From Nature News:

Mysterious changes in the stratosphere may have offset greenhouse effect.

A puzzling drop in the amount of water vapour high in the Earth's atmosphere is now on the list of possible culprits causing average global temperatures to flatten out over the past decade, despite ever-increasing greenhouse-gas emissions.

Although the decade spanning 2000 to 2009 ranks as the warmest on record, average temperatures largely levelled off following two decades of rapid increases. Researchers have previously eyed everything from the Sun and oceans to random variability in order to explain the pause, which sceptics have claimed shows that climate models are unreliable.

Scientists Suggest Simulated Volcanic Eruptions Could Stem Global Warming

Scientists believe that simulating the effects of a volcanic eruption could help cool the planet, halting global warming. Fenton/AP

From The New York Daily News:

A group of scientists have a plan to save the planet - volcanoes!

Simulated volcanoes, to be precise.

The idea, detailed by a trio of environmental scientists in an editorial for the journal, Nature, would potentially be cheaper than forcing industries to cut carbon emissions.

"Many scientists have argued against research on solar radiation management," write David Keith of the University of Calgary in Canada, Edward Parson of the University of Michigan and Granger Morgan of Carnegie Mellon University.

From Times Online:

Using biofuel in vehicles may be accelerating the destruction of rainforest and resulting in higher greenhouse gas emissions than burning pure petrol and diesel, a watchdog said yesterday.

The Renewable Fuels Agency also warned that pump prices could rise in April because of the Government’s policy of requiring fuel companies to add biofuel to petrol and diesel. More than 1.3 million hectares of land — twice the area of Devon — was used to grow the 2.7 per cent of Britain’s transport fuel that came from crops last year.

From The New York Times:

SAN FRANCISCO — Apple has generated a lot of chatter with its new iPad tablet. But it may not be quite the conversation it wanted.

Many women are saying the name evokes awkward associations with feminine hygiene products. People from Boston to Ireland are complaining that “iPad,” in their regional brogue, sounds almost indistinguishable from “iPod,” Apple’s music player. The problem may be worse outside the United States; Japanese does not even have a sound for the “a” in iPad.

NASA To Get More Money, But Must Scratch Moon Plan

From ABC News/AP:

Officials say Obama rules out NASA return to moon; budgets money for private space taxis.

President Barack Obama is essentially grounding plans to return astronauts to the moon and instead is sending NASA in new directions with roughly $6 billion more.

A White House official confirmed Thursday that when next week's budget is proposed, NASA will get an additional $5.9 billion over five years, as first reported in Florida newspapers. Some of that money will be used to extend the life of the International Space Station to 2020. The official said it also will be used to entice companies to build private spacecraft to ferry astronauts to the space station after the space shuttle retires.

Navy Says Video Games Can Boost "Fluid Intelligence" of Warfighters

America's Army Get your virtual warfare on U.S. Army

From Popular Science:

Military simulators that resemble video games have obvious training benefits for warfighters, but U.S. Navy scientists also say that video games can boost brainpower and produce cognitive improvements that last up to two and a half years.

The Office of Naval Research (ONR) hopes that video game-like training can help warfighters hone their "fluid intelligence," or ability to confront and solve new problems. Such research feeds into a new sense that the human brain can continue to adapt and improve itself beyond early adulthood, and may allow soldiers to better adjust to the changing tactics and environment of the modern-day battlefield.

With iPad, Apple Still Has A Fatal Attraction For AT&T


From Gadget Lab:

When Steve Jobs said Apple’s new iPad tablet would have 3G data service from AT&T during Wednesday’s press conference, sighs of disgust could be heard from the audience, presumably from disgruntled iPhone customers.

Prior to the unveiling of the 9.7-inch device Wednesday, a few vague rumors suggested Verizon would carry the tablet. Instead, Jobs announced two versions of the iPad: a Wi-Fi only model and an unlocked, Wi-Fi + 3G model for use on GSM networks. The Verizon network operates on the CDMA standard, meaning Verizon won’t be able to support the iPad.

From Scientific American:

Toyota, the world's largest automaker, has suspended sales of certain models and recalled millions of older ones as its engineers search for the elusive source of a sticky—and dangerous—accelerator problem

During the past few days, Toyota Motor Corp., has taken the unprecedented step of halting sales in the U.S., Europe and China of some of its most popular car and truck models. The reason: potential defects that cause the vehicles to speed up without warning and run out of control. The move follows a huge (and growing) recall of older Toyota vehicles last week. Safety Research and Strategies, based in Rehoboth, Mass., has reportedly implicated the sudden unintended acceleration problem to 2,274 incidents in Toyota vehicles, causing 275 crashes and at least 18 fatalities since 1999.

No Moon Trips: Obama's Space Vision A 'Paradigm Shift'

From Space.com:

President Obama's plan for America's space program, according to early reports, represents a fundamental shift for human spaceflight, some experts say.

The reports suggest the Obama administration intends to move toward relying on commercially-built spacecraft, rather than NASA's own vehicles, to carry humans to low-Earth orbit. The plan would also involve extending the International Space Station's lifetime and abandoning current plans to send astronauts on moon missions in the 2020s.

From Science Daily:

Science Daily (Jan. 27, 2010) — The paper, by Professor João Zilhão and colleagues, builds on his earlier research which proposed that, south of the Cantabro-Pyrenean mountain chain, Neanderthals survived for several millennia after being replaced or assimilated by anatomically modern humans everywhere else in Europe.

Although the reality of this 'Ebro Frontier' pattern has gained wide acceptance since it was first proposed by Professor Zilhão some twenty years ago, two important aspects of the model have remained the object of unresolved controversy: the exact duration of the frontier; and the causes underlying the eventual disappearance of those refugial Neanderthal populations (ecology and climate, or competition with modern human immigrants).

From Live Science:

Physicists may be one step closer to achieving a form of clean energy known as nuclear fusion, which is what happens deep inside the cores of stars.

A recent experiment with a giant levitating magnet was able to coax matter in the lab to extremely high densities — a necessary step for nuclear fusion.

When the density is high enough, atomic nuclei — the protons and neutrons of atoms — literally fuse together, creating a heavier element. And if the conditions are right that fusion can release loads of energy.

New home entertainment technology aims to transform a 3-D viewer’s experience.

It seems every year is heralded as “the year 3-D home entertainment will take off.” Yet the moment never really arrives.

Last year saw huge strides for 3-D movies in theaters. Each of the seven top-grossing 3-D movies of all time came out in 2009. Atop the list sits “Avatar,” which raked in more than $1.6 billion worldwide and became history’s second biggest box-office hit in only a few weeks. And animation powerhouse Pixar, hungry for similar successes, stuck to its pledge to only make 3-D movies from now on.

This is great news for theatergoers, but there are very few ways to bring the extra dimension home with you.

The most common reasons for medical evacuation of military personnel from war zones in Iraq and Afghanistan in recent years have been fractures, tendonitis and other musculoskeletal and connective tissue disorders, not combat injuries, according to results of a Johns Hopkins study published January 22 in the Lancet. "Most people think that in a war, getting shot is the leading cause of medical evacuation, but it almost never is," says study leader Steven P. Cohen, M.D., associate professor of anesthesiology at the Johns Hopkins University School of Medicine and a colonel in the U.S. Army Reserves. "As in the past, disease and non-battle-related injuries continue to be the major sources of service-member attrition and that's not likely to change. It's likely to get worse."

Navy Pledges Green Strike Group By 2012

The Navy is Going Green The Navy will demonstrate a Green Strike Group, like the George Washington Carrier Strike Group pictured here, by 2012; the group will run on biofuels and nuclear power rather than fossil fuels.

From Popular Science:

Militaries have a tough, often messy job to do, and as such taking steps to polish their green credentials generally isn’t a high priority. But the potential cost savings – not to mention the tactical advantages – of going green are not lost on U.S. Armed Forces’ top brass. The Army has pursued “zero footprint” base camps, and the Air Force is looking into a variety of alternative propellants that could be turned into jet fuel. Now the Navy is going green, signing a memorandum of understanding with the USDA to demo a Green Strike Group of biofuel- and nuclear-powered vessels by 2012.

Obama Aims To Ax Moon Mission


From Orlando Sentinel:

NASA's plans to return astronauts to the moon are dead. So are the rockets being designed to take them there — that is, if President Barack Obama gets his way.

When the White House releases his budget proposal Monday, there will be no money for the Constellation program that was supposed to return humans to the moon by 2020. The troubled and expensive Ares I rocket that was to replace the space shuttle to ferry humans to space will be gone, along with money for its bigger brother, the Ares V cargo rocket that was to launch the fuel and supplies needed to take humans back to the moon.

There will be no lunar landers, no moon bases, no Constellation program at all.
