From Live Science:

Three swirling storms are roaring across the Atlantic with nervous East Coast residents keeping a close eye on the conveyor belt of tropical activity as hurricane season enters its busiest time.

Hurricane Earl is bearing down on the Carolinas and has strengthened into a Category 4 storm, with maximum winds of 145 mph (235 kph), according to the latest update from the National Hurricane Center (NHC). Category 3 storms or higher on the Saffir-Simpson scale of hurricane strength are classified as major hurricanes. [In Images: Hurricane Hunters Flying into Earl.]

Throat Cancer Rates Soar In Men

From The Telegraph:

Throat cancer cases have soared by 50 per cent in men in the last 25 years due to obesity and bad diet, researchers have found.

Back in the eighties around 2,600 men were diagnosed with oesophageal cancer every year but now the figure is more than 5,100.

The most dramatic rise was among men in their 50s, as rates increased by 67 per cent over the same period.

When Drones Go Wild

When Drones Go Rogue In Friendly Skies, How Do We Bring Them Home? -- Popular Science

An advanced fly-by-wire system capable of landing grossly damaged unmanned aircraft—demonstrated on video saving a plane missing 80 percent of one wing—is key to solving one of unmanned flight’s biggest problems.

Word spread last week that a rogue MQ-8B Fire Scout copter drone entered restricted airspace just 40 miles shy of Washington D.C. after losing contact with its operators. The revelation occurred smack in the middle of AVUSI 2010, the world’s largest UAV tradeshow. And it served as a poignant reminder that all the game-changing technology on display here at the Denver Convention Center still has some innovating to do, especially when flight crews lose control of their unmanned craft.

Shape-Shifting Robot Compensates For Damaged Limb

From New Scientist:

Think that shape-shifting robots, or ones that march on no matter how many limbs they lose, are just for Terminator films? Think again. A team of European roboticists have developed software that allows a modular robot to adapt when one part stops working.

David Johan Christensen at the University of Southern Denmark in Odense, working with Alexander Spröwitz and Auke Ijspeert at the Swiss Federal Institute of Technology in Lausanne, simulated a quadruped robot constructed from a dozen Roombots – identical rounded robots that have been developed in Lausanne and which can combine to form a variety of modular shapes (see picture).

Double Space Strike 'Caused Dinosaur Extinction'

From The BBC:

The dinosaurs were wiped out 65 million years ago by at least two space impacts, rather than a single strike, a new study suggests.

Previously, scientists had identified a huge impact crater in the Gulf of Mexico as the event that spelled doom for the dinosaurs.

Now evidence for a second impact in Ukraine has been uncovered.

This raises the possibility that the Earth may have been bombarded by a whole shower of space rocks.

Does Langage Influence Culture?

Lost In Translation -- Wall Street Journal

New cognitive research suggests that language profoundly influences the way people see the world; a different sense of blame in Japanese and Spanish.

Do the languages we speak shape the way we think? Do they merely express thoughts, or do the structures in languages (without our knowledge or consent) shape the very thoughts we wish to express?

Take "Humpty Dumpty sat on a..." Even this snippet of a nursery rhyme reveals how much languages can differ from one another. In English, we have to mark the verb for tense; in this case, we say "sat" rather than "sit." In Indonesian you need not (in fact, you can't) change the verb to mark tense.

The number he was referring to, which goes by the symbol alpha and the rather more long-winded name of the fine-structure constant, is magic indeed. If it were a mere 4% bigger or smaller than it is, stars would not be able to sustain the nuclear reactions that synthesise carbon and oxygen. One consequence would be that squishy, carbon-based life would not exist.

Earliest Fossil Evidence Of Humans In Southeast Asia?

Archaeologists excavating Callao Cave in the Philippines.
Armand Salvador Mijares

From Earth Magazine:

Modern humans reached the islands of Southeast Asia by approximately 50,000 years ago, but our ancestors’ journey was not easy. Even during times of low sea level, a voyage to some of these islands would have required crossing open water, leaving many scientists to wonder how humans arrived on the most isolated islands. Now the story is growing more complicated: A group of archaeologists has discovered a 67,000-year-old foot bone that they say represents the earliest-known presence of humans in the northern Philippines and may be among the oldest-known traces of modern humans in all of Southeast Asia — that is, if the bone truly belongs to Homo sapiens. The bone’s small size and unusual features make it difficult to determine exactly which species of Homo it was — Homo sapiens, Homo floresiensis or something else?

The U.S. Sniper's More Accurate, Quieter Rifle -- Popular Mechanics

Army Snipers in Afghanistan will receive an improved rifle this fall.

For snipers, every war is different. Recognizing the differences between conditions in Iraq and Afghanistan, the Army is now selecting a contractor to upgrade the 22-year-old Remington bolt-action rifle to become a more effective killing machine. The Army will pour about $5.6 million into upgrades to the M24, with the new gear expected to be delivered to troops by this fall. The M24's barrel is being modified to shoot heavier .300 Winchester Magnum rounds, instead of the 7.62mm NATO ammunition, which should extend the rifle's maximum effective range by hundreds of yards to a maximum of about 1400 yards. The suppressor will reduce the noise and flash of the gun so snipers can stay in their hiding positions much longer after they fire.

When Will We Be Able To Build Brains Like Ours?

From Scientific American:

Sooner than you think -- and the race has lately caused a 'catfight'.

When physicists puzzle out the workings of some new part of nature, that knowledge can be used to build devices that do amazing things -- airplanes that fly, radios that reach millions of listeners. When we come to understand how brains function, we should become able to build amazing devices with cognitive abilities -- such as cognitive cars that are better at driving than we are because they communicate with other cars and share knowledge on road conditions. In 2008, the National Academy of Engineering chose as one of its grand challenges to reverse-engineer the human brain. When will this happen? Some are predicting that the first wave of results will arrive within the decade, propelled by rapid advances in both brain science and computer science. This sounds astonishing, but it’s becoming increasingly plausible. So plausible, in fact, that the great race to reverse-engineer the brain is already triggering a dispute over historic “firsts.”
