East Coast Cod Found To Be Recovering -- CBC

New evidence shows that Atlantic cod off Nova Scotia are recovering from their dramatic collapse two decades ago — and that the ecosystem is recovering with them.

That suggests major changes to marine ecosystems can be reversed with time, says a Canadian study published Wednesday in the scientific journal Nature.

It also "bodes well" for other cod populations further north along the East Coast that have yet to recover, says the study, led by researcher Kenneth Frank at the Bedford Institute of Oceanography in Dartmouth, N.S.

A New Type Of Airship

New Type Of Flying Vehicle In Development -- Voice Of America

A California company is developing a new type of airship for transporting cargo and, possibly, passengers. It is not an airplane and not a blimp, but has elements of both. The vehicle uses new technology and has commercial and military applications.

The new flying ship from the Aeros Corporation is called an Aeroscraft, and is designed to carry more than 50 tons of cargo and make deliveries thousands of kilometers away.

Remote Control Toy Trucks Save Lives In Afghanistan

Afghanistan War: Hobbyists' Toy Truck Saves 6 Soldiers' Lives -- ABC News

Staff Sgt. Christopher Fessenden is on duty in Afghanistan now after tours with the Army in Iraq. He has traveled with standard-issue equipment -- weapons, helmet, uniform, boots and so forth -- plus a radio-controlled model truck his brother sent.

The truck is not a toy to him. He says it just saved six soldiers' lives.

"We cannot thank you enough," said Sgt. Fessenden in an email from the front that his brother Ernie, a software engineer in Rochester, Minn., shared with ABC News.

Boeing Is Looking For Astronauts

An artist's conception shows Boeing's CST-100 crew-carrying spaceship atop an Atlas 5 rocket on a launch pad. Such a craft could fly to the International Space Station as early as 2015. Boeing

Boeing Chooses A Rocket, Looks For Astronauts To Fly On It -- MSNBC

Atlas 5 to be used for tests of new spaceship for NASA's use; pilots wanted.

Test flights of The Boeing Co.'s future crew-carrying spaceship would be conducted starting as early as 2015 on United Launch Alliance's Atlas 5 rocket, executives announced Thursday.

Whether Boeing's CST-100 capsule actually flies in that timeframe depends on whether NASA provides the necessary development funding, said John Elbon, the aerospace company's manager for the commercial crew project. But just in case, Boeing is already looking for pilots who could help with the design and testing of the craft.

The Negative Side Of Solar And Wind Power Projects

The Dark Side Of Solar And Wind Power Projects -- L.A. Times

Building and maintaining solar and wind power projects can be hazardous, and industry watchdogs worry that the push for more green energy places more workers and bystanders in harm's way.

They can look benign from a distance — solar panels glistening in the sun or turbines gently churning with the breeze to produce electricity for hundreds of thousands of homes. But building and maintaining them can be hazardous.

Accidents involving wind turbines alone have tripled in the last decade, and watchdog groups fear incidents could skyrocket further — placing more workers and even bystanders in harm's way — because a surge in projects requires hiring hordes of new and often inexperienced workers.

Dieting Forces Brain To Eat Itself, Scientists Claim -- The Telegraph

Dieters struggle to lose weight because a lack of nutrition forces their brain cells to eat themselves, making the feeling of hunger even stronger, scientists claim.

Like other parts of the body, brain cells begin to eat themselves as a last-ditch source of energy to ward off starvation, a study found.

The body responds by producing fatty acids, which turn up the hunger signal in the brain and increase our impulse to eat.

Researchers from the Albert Einstein College of Medicine at Yeshiva University in New York said the findings could lead to new scientifically proven weight loss treatments.

Water On Mars?

Dark Streaks On Mars Could Be Water -- The Telegraph

Dark finger-like channels stretching across the surface of Mars could be streams of salty water running down the sides of craters, scientists have claimed.

The clusters of trails, which fade during winter and reappear in warmer months, could prove to be the first solid evidence of liquid water currently existing on the red planet.

Scientists are convinced water probably flowed across the surface of the planet at some distant point in history, but have only been able to detect samples of frozen water near the surface.

The U.S. Army Kills The Robotic Vehicle MULE Program

Why The Army Killed The Robotic Vehicle MULE -- Popular Mechanics

Over the weekend, the U.S. Army killed a Lockheed Martin program to build a heavy six-wheeled robot capable of hauling gear and countering improvised explosive devices. Here's why they did it, and what it says about the future of Army bots.

Late last Friday, July 29, the Army formally canceled the Multi-Function Utility/Logistics and Equipment Vehicle, a heavyweight, six-wheeled robot known as the MULE, which was built by Lockheed Martin. The MULE program was meant to produce three variants of combat robots: One to haul gear, another to counter improvised explosives and a heavily armed version. According to the Army, however, other programs had equaled or bettered the autonomous navigation research at MULE—yet there are plenty of other reasons that Lockheed's program got the ax. Here's what MULE's demise tells us about the Army's future:

The Man Who Would Stop Time -- PopSci

Bill Andrews has spent two decades unlocking the molecular mechanisms of aging. His mission: to extend the human life span to 150 years--or die trying

Bill Andrews’s feet are so large, he tells me, that back when he was 20 he was able to break the Southern California barefoot-waterskiing distance record the first time he put skin to water. Then he got ambitious and went for the world speed record. When the towrope broke at 80 mph, he says, “they pulled me out of the water on a stretcher.”

Swiss company reconstructs King Tut's DNA profile from Discovery Channel documentary
Results show he belonged to 'haplogroup' common to half of Western European men
Claims disputed by fellow geneticists

A Swiss genetics company has claimed that up to 70 per cent of British men are related to the Egyptian Pharaoh Tutankhamun.

Scientists at Zurich-based DNA genealogy centre, iGENEA, say they have reconstructed the DNA profile of the boy Pharaoh based on a film that was made for the Discovery Channel.

The results showed that 'King Tut' belonged to a genetic profile group, known as haplogroup R1b1a2, to which more than 50 per cent of all men in Western Europe belong, indicating that they share a common ancestor.

World's Oldest Living Animal Is 178-Year-Old Tortoise Called Jonathan -- The Telegraph

As a photograph it looks fairly unremarkable - a tortoise nibbles at the grass in front of a Boer War prisoner and guard.

But the pictures helps to mark the reptile as the oldest animal on the planet.

Jonathan, the tortoise, is believed to be 178-years-old and was about 70 at the time the black and white picture was taken.

He was photographed during the Boer War around 1900, and his life has spanned eight British monarchs from George IV to Elizabeth II, and 50 prime ministers.

Two Moons Above Earth May Have Collided To Create One, Study Says -- L.A. Times

Scientists say such a collision could explain why the moon is lopsided and why its far side is covered with mountains.

Once upon a time, the sky above Earth may have held two moons — until they smashed into each other to create the lunar body we know today. Such a collision early in the solar system's history could explain why the moon is lopsided, and why its far side looks so different from the face we can see, according to a report in Thursday's edition of the journal Nature.
