From Live Science:

Futurists have proposed that extinct animals could be resurrected some day via cloning of their DNA extracted from bone or frozen tissue.

There is little agreement on this, but a new project to store tiny samples of tissue from endangered animals at New York's natural history museum again prompts questions on whether this approach might be insurance against extinction, not just a valuable data repository for biologists.

From Stltoday:

WASHINGTON -- The best time to learn a foreign language: Between birth and age 7. Missed that window?

New research is showing just how children's brains can become bilingual so easily, findings that scientists hope eventually could help the rest of us learn a new language a bit easier.

"We think the magic that kids apply to this learning situation, some of the principles, can be imported into learning programs for adults," says Dr. Patricia Kuhl of the University of Washington, who is part of an international team now trying to turn those lessons into more teachable technology.

Gates Puts Feynman Lectures Online

From New York Times:

Microsoft Chairman Bill Gates believes that if he had been able to watch physicist Richard Feynman lecture on physics in 1964 his life might have played out differently.

Mr. Gates, of course, is legendary as a Harvard University dropout who went on to create the world’s most successful software firm. He has told associates that if had watched the lectures earlier in his life he might have become a physicist instead of a software entrepreneur.

From Science Daily:

ScienceDaily (July 22, 2009) — New developments in a substance which emits brilliant light could lead to a revolution in lighting for the home and office in five years, claims a leading UK materials scientist, Professor Colin Humphreys of Cambridge University. The source of the huge potential he foresees, gallium nitride (GaN), is already used for some lighting applications such as camera flashes, bicycle lights, mobile phones and interior lighting for buses, trains and planes.

But making it possible to use GaN for home and office lighting is the Holy Grail. If achieved, it could reduce the typical electricity consumption for lighting of a developed country by around 75% while delivering major cuts in carbon dioxide emissions from power stations, and preserving fossil fuel reserves.

Business-class return to space, please (Image:NASA)

From New Scientist:

ON A bright autumn morning five years ago, the space-flight community was turned on its head by a little teardrop-shaped spacecraft built in a small workshop in California's Mojave desert. The successful flight of SpaceShipOne on 29 September 2004, the first of two flights en route to winning the $10 million Ansari X prize, seemed to usher in a new era of space travel - one in which space flight would be affordable, frequent and, perhaps most importantly, accessible to all.

Massive New Zealand Quake Moves Country West

From Yahoo News/AP:

WELLINGTON, New Zealand – Southern New Zealand has moved slightly closer to the east coast of neighboring Australia as a result of a massive earthquake last week off the country's South Island, a scientist said Wednesday.

The magnitude 7.8 quake, centered in the ocean near Resolution Island in the country's Fiordland region, twisted South Island out of shape and moved its southern tip 12 inches (30 centimeters) closer to Australia, seismologist Ken Gledhill said.

Gledhill, director of government-owned GNS Science's "GeoNet" national earthquake monitoring project, said the island's geographic shift showed the immensity of the forces involved.

John S. Barry, Main Force Behind WD-40, Dies at 84

From CNBC:

John S. Barry, an executive who masterminded the spread of WD-40, the petroleum-based lubricant and protectant created for the space program, into millions of American households, died on July 3 in the La Jolla neighborhood of San Diego. He was 84.

The cause was pulmonary fibrosis, a lung disease, said Garry Ridge, president and chief executive of the WD-40 Company.

The company says surveys show that WD-40, the slippery stuff in the blue and yellow aerosol can, can be found in as many as 80 percent of American homes and that it has at least 2,000 uses, most discovered by users themselves. These include silencing squeaky hinges, removing road tar from automobiles and protecting tools from rust.

Unsung Heroes Save Net From Chaos

The same social structures that drive Wikipedia also keep the net healthy

From BBC:

Crack teams of volunteers keep the net online and functioning, according to leading internet lawyer Jonathan Zittrain of Harvard University.

The way data is divided up and sent around the internet in many jumps makes it "delicate and vulnerable" to attacks or mistakes, he said.

However, he added, the "random acts of kindness" of these unsung heroes quietly keep the net in working order.

Professor Zittrain's comments came at the TED Global conference in Oxford.

Incidents such as when the Pakistan government took YouTube offline in 2008 exposed the web's underlying fragility, he explained.

For Scientists, Moon Rocks Tell Story Of A Young Earth

From Philadelphia Inquirer:

For 40 years, the rocks hauled back from the moon have been changing the history of the Earth as we knew it.

The lunar rocks suggest that a smaller planet slammed into ours 4.5 billion years ago, creating the moon and enlarging the Earth. They tell the tale of a storm of space debris violently pounding both the Earth and moon, perhaps triggered by a dramatic reshuffling of the entire solar system.

Scientists today are still studying those rocks, hoping to decipher whether life had already emerged before the near-apocalyptic pummeling 3.9 billion years ago - and, incredibly, survived.

Scientists Capitalize On Extended Solar Eclipse

On Wednesday, 2009 July 22, a total eclipse of the Sun is visible from within a narrow corridor that traverses half of Earth. The path of the Moon's umbral shadow begins in India and crosses through Nepal, Bangladesh, Bhutan, Myanmar and China. After leaving mainland Asia, the path crosses Japan's Ryukyu Islands and curves southeast through the Pacific Ocean where the maximum duration of totality reaches 6 min 39 s. A partial eclipse is seen within the much broader path of the Moon's penumbral shadow, which includes most of eastern Asia, Indonesia, and the Pacific Ocean. (Credit: F. Espenak / NASA's Goddard Space Flight Center)

From Science Daily:

ScienceDaily (July 22, 2009) — Scientists at an observatory outside Hangzhou joined residents and tourists across China and India in observing the longest total solar eclipse in a century and probably the most-viewed ever.

The moon's shadow traced a path across the world's two most populous countries before racing across the Pacific, providing a view of totality for five minutes and 36 seconds for scientists gathered here from around the world as part of the Williams College Eclipse Expedition.

Human Stabbed A Neanderthal, Evidence Suggests

Steven Churchill of Duke University is holding a replica of a Neanderthal-type spear (left hand) and a spear thrower and dart (right hand) that would have been similar to weapons used by early modern humans tens of thousands of years ago. Credit: Duke Photo by Les Todd.

From Live Science:

Newly analyzed remains suggest that a modern human killed a Neanderthal man in what is now Iraq between 50,000 and 75,000 years ago. The finding is scant but tantalizing evidence for a theory that modern humans helped to kill off the Neanderthals.

The probable weapon of choice: A thrown spear.

The evidence: A lethal wound on the remains of a Neanderthal skeleton.

The victim: A 40- to 50-year-old male, now called Shanidar 3, with signs of arthritis and a sharp, deep slice in his left ninth rib.

Made In China: The Monster Dust Cloud That Completed A Full Circle Of The Globe In Just Thirteen Days

Phenomenal: An enormous dust cyclone swirls over northeastern China

From The Daily Mail:

It was a natural phenomenon that would have tested the limits of even Mr Muscle.

Scientists in Japan have found that clouds generated by a massive dust storm in China's Taklimakan desert in 2007 completed more than one full circle around the planet in just 13 days.

And measuring around 1.9 miles vertically and up to 1,242 miles horizontally, the dust cloud - which formed in the northwestern region of Xinjiang - stayed in that formation the whole way.

How To Use Your iMac As A Second Screen

From Popular Mechanics:

Can you use your iMac's built-in monitor as a second screen for another computer? The answer is yes. Here's how.

Q:
My iMac has a built-in monitor. Is there a way of using this as a second screen for another computer?

A:
When it comes to screen space, you can never go overboard. Large monitor and multiscreen set-ups make it easy to multitask, and have been shown by a number of studies to boost productivity. It’s a shame, then, that Apple doesn’t build video input jacks into its iMacs—these all-in-one computers have a built-in monitor, and it’d be nice to be able to use it with other systems. This would be particularly useful for laptop users looking for a way to expand screen space when they aren’t on the road.

But even without an input jack, you can still put an iMac to work as an external monitor for another com­puter. You’ll need a program called ScreenRecycler, which employs what is called the VNC, or Virtual Network Computing, protocol. VNC is usually used as a way to allow one computer to remotely access and control ­another, but ScreenRecycler uses it to turn the second computer into an adjunct monitor. Note, though, that while the second screen can come from any type of computer (even a laptop), the com­puter you’re working on has to be a Mac.

A Reprogrammable Space Probe Design For Mission Multitasking in Orbit

The Juno Space Probe: Honest to blog courtesy of NASA

From Popsci.com:

Multi-purpose hardware lets Japanese satellite change its mission on the fly.

Right now, thousands of satellites are circling the Earth. They're a diverse bunch. Some relay telephone calls, some spy on North Korea, some monitor the weather. But they all have one thing in common: each can only do one thing. A spy satellite can't suddenly start forecasting storms, and a communications satellite can't study asteroids.

Well, that's all about to change.

Researchers at the Institute of Space Systems at the University of Stuttgart, Germany, have designed a variable-function satellite that can alter its mission on the fly.

From Yahoo News/AP:

CAPE CANAVERAL, Fla. – When it comes to sneezing in a spacesuit while in the void of space, it is best to aim well.

That's the advice lead spacewalker David Wolf offered Tuesday while answering one of the questions posted on YouTube for the crew of the space shuttle Endeavor.

"I've done it quite a few times, most recently yesterday," said Wolf, who led the mission's second spacewalk Monday and was set to go on a third spacewalk Wednesday. "You learn in training, and I don't know how to say this, aim well. It can mess up your view and there is no way to clear it."
