From Science Daily:

Science Daily (Dec. 16, 2009) — The conversations neurons have as they form and recall memories have been decoded by Medical College of Georgia scientists.

The breakthrough in recognizing in real time the formation and recollection of a memory opens the door to objective, thorough memory studies and eventually better therapies, said Dr. Joe Tsien, neuroscientist and co-director of MCG's Brain & Behavior Discovery Institute. He is corresponding author on the study published Dec. 16 in PLoS ONE.

Time-Lapse Photos Show Dramatic Erosion of Alaska Coast

A new study indicates part of the northern Alaska coastline is eroding by up to 45 feet annually due to declining sea ice, warming seawater and increased wave activity. Credit: Robert S. Anderson, University of Colorado.

From Live Science:

SAN FRANCISCO — Time-lapse photography of crumbling Alaskan coastlines is helping scientists understand the "triple whammy" of forces eroding the local landscape: declining sea ice, warming ocean waters and more poundings by waves.

The erosion rates from these forces are greater than anything seen along the world's coastlines, with the coast midway between Alaska's Point Barrow and Prudhoe Bay falling into the ocean in the inland direction by up to one-third the length of a football field annually, scientists have found.

New Underwater Explorers Go Where Scientists Can't



From Popular Mechanics:

Last week, an unmanned robot completed a 3300-mile trek across the Atlantic Ocean for the first time. The 134-pound robot, a glider named the Scarlet Knight, spent months at sea, gathering data on ocean temperature and salinity between the water's surface down to 600 feet below. The Scarlet Knight is just one of many new technologies scientists are turning to in order to research oceans, rivers and lakes—areas that are impractical, and in some cases impossible, for researchers to access themselves. By employing everything from robots to, yes, tadpoles, scientists hope to learn more about how climate change and pollution are affecting the earth's water. Here is some of the newest tech aiding scientists.

Who Should Be the First Band To Play in Space?

Spandau Ballet

From Popular Science:

This morning an odd story surfaced and began orbiting the Web: Sir Richard Branson's Virgin Galactic signed '80s rock heartthrobs (now aging '80s rock heartthrobs) Spandau Ballet to be the first band to rock out in space. Citing a press release of dubious origin, several blogs and even the UK's Daily Mail reported the story, even naming possible songs the group would play during a five-minute weightless set.

But we can all breathe a collective sigh of relief. The Internet has hoodwinked us once again.

The Beckoning Silence: Why Half Of The World's Languages Are in Serious Danger Of Dying Out

Language hotspots are areas with extreme linguistic diversity, containing many highly endangered and underdocumented languages

From The Independent:

Of the 6,500 languages spoken in the world, half are expected to die out by the end of this century. Now, one man is trying to keep those voices alive by reigniting local pride in heritage and identity.

High up, perched among the remote hilltops of eastern Nepal, sits a shaman, resting on his haunches in long grass. He is dressed simply, in a dark waistcoat and traditional kurta tunic with a Nepalese cap sitting snugly on his head. To his left and right, two men hold recording devices several feet from his face, listening patiently to his precious words. His tongue elicits sounds alien to all but a few people in the world, unfamiliar even to those who inhabit his country. His eyes flicker with all the intensity of a man reciting for the first time to a western audience his tribe's version of the Book of Genesis, its myth of origins.

That analysis concluded that more than half of the large mammals in North America (the 'megafauna') disappeared about 13,000 years ago.

From New Scientist:

Baby black holes are puny compared with their humongous cousins at the centres of galaxies, but their birth may spew out the universe's mightiest particles.

Subatomic particles are routinely detected smashing into Earth's atmosphere at incredibly high energies, but the origin of these ultra-high-energy cosmic rays (UHECRs) remains a mystery. Some have argued that energy released by the collapse of a massive single star to form a black hole might produce the UHECRs, but the rate of such events is too low.

Lost Giants: Did Mammoths Vanish Before, During And After Humans Arrived?

From Scientific American:

Three studies seem to disagree as to when mammoths, saber-toothed cats and other North American megafauna disappeared.

Before humans arrived, the Americas were home to woolly mammoths, saber-toothed cats, giant ground sloths and other behemoths, an array of megafauna more impressive than even Africa boasts today. Researchers have advanced several theories to explain what did them in and when the event occurred. A series of discoveries announced in the past four weeks, at first glance apparently contradictory, adds fresh details to the mystery of this mass extinction.

Octopuses Use Coconut Shells To Make Portable Lairs

Researchers watched as the eight legged creatures, not much bigger than the coconuts themselves, collected shell halves, stacked them two together, and transported them awkwardly under their bodies over distances of up to 20 metres.

Then when they arrived at their destination the octopuses in Indonesia used the two halves like shields to construct a makeshift shelter.

Boeing 787 Dreamliner Finally Takes To The Skies In First Test Flight - Two Years Later Than Originally Planned

Boeing Co made the first successful test flight of its 787 Dreamliner today, almost two and a half years after the new, fuel-efficient plane was supposed to fly.

The lightweight carbon and titanium plane, promising to save airlines million of dollars in fuel and maintenance costs, has been hampered by a shortage of bolts, faulty design and a two-month strike.

But today Boeing sent the plane on a four-hour flight from Paine Field in Everett, Washington, at 10am local time, to test it as it flew around the local area.

From Cosmos/AFP:

TOKYO: Japanese researchers last week said they had found a way to make plant leaves absorb more carbon dioxide - an innovation that may help ease global warming and boost food production.

The Kyoto University team found that soaking germinated seeds in a protein solution raised the number of pores, or stomas, on the leaves that inhale CO2 and release oxygen, said chief researcher Ikuko Hara-Nishimura.

"A larger number means there are more intake windows for carbon dioxide, contributing to lowering the density of the gas," she said.

US And Russia In 'Secret' Cyber Warfare Talks -- The Telegraph

Russia and the United States are discussing how best to safeguard the internet against hostile attacks.

The talks, which are taking place between the US, Russia and a United Nations arms control committee, are aimed at finding ways of strengthening internet security and limiting the military use of cyberspace, according to a report in the New York Times.

Online attacks against government websites, corporate computer systems and other business-critical infrastructures have increased in the last two years. Anonymous hackers have managed to access the Pentagon's computers and overwhelm government websites, and President Obama has ordered an urgent review of the United States' internet security.

Apple’s Next Media Frontier Will Be Streaming Video

From Gadget Lab:

Video entertainment was “the one that got away” from Apple, but recent moves reveal the company is taking a second stab at the category, and that streaming video will play a major role.

The addition of video cameras to Apple’s latest iPhone and iPod Nano were just the first hints of the company’s new personal-media strategy. The company is also building a 500,000 square-foot data center in North Carolina, which could provide the massive bandwidth required for ubiquitous streaming video. And Apple’s recent acquisition of Lala suggests it’s interested in rebooting iTunes into a streaming service, according to Wall Street Journal. That means music, in Lala’s case, but the same infrastructure could be shared with streaming video.

From Science Daily:

ScienceDaily (Dec. 12, 2009) — Studies of one of the galaxy's most active black-hole binaries reveal a dramatic change that will help scientists better understand how these systems expel fast-moving particle jets.

Binary systems where a normal star is paired with a black hole often produce large swings in X-ray emission and blast jets of gas at speeds exceeding one-third that of light. What fuels this activity is gas pulled from the normal star, which spirals toward the black hole and piles up in a dense accretion disk.
