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.

How A Glass Or Two Of Champagne Really Does Lift The Heart

From The Guardian:

Fizz made with black grapes shares benefits of red wine for heart and blood circulation, scientists find.

Scientists are delivering some unexpected cheer this Christmas. They have found that a couple of glasses of champagne a day are good for your heart and blood circulation.

Nor, they believe, are the benefits limited to expensive fizz: cheaper alternatives such as cava and prosecco may offer similar effects.

From Future Pundit:

10000 to 7600 year old woolly mammoth DNA was found frozen in Alaska tundra. So this begs the obvious question: Is the DNA good enough to sequence and use some day to bring back the woolly mammoth?

The work of U of A Earth and Atmospheric Sciences professor Duane Froese and his colleagues counters an important extinction theory, based on radiocarbon dating of bones and teeth. 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.

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.

Americans Are Info-Junkies

Despite having access to computers and other electronic distractions, Americans on average spend about 60 percent of their information consumption time watching TV or listening to radio. Credit: UCSD

From Live Science:

Americans are known for gorging on food, but we're also gluttons of another sort: A new study finds that the average American consumes more than 34 gigabytes of video, music and words a day—and that's only on our free time.

One byte of information is equivalent to one letter of text. One gigabyte is equal to roughly 8 minutes of high definition video. Thirty-four gigabytes of data would fit on about 7 DVD disks or 1.5 Blu-ray disks.

A mix of old and new media contribute to our daily information diet, the study finds, including TV, radio, books, the Internet, movies, text messages and video games.

Octopuses Use Coconut Shells To Make Portable Lairs

From The Telegraph:

Octopuses collect coconuts from the sea bed and use them as portable shelters, scientists have found in the latest example of animals using tools.

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.

From The Guardian:

Neuroscientist John Cacioppo says social pain is akin to physical pain. So what can be done to make it better?

'Tis the season to be lonely. Half a million pensioners will spend Christmas Day alone, while nearly three in five people over 55 will be wishing they could see more of their family. This isn't just a seasonal or British phenomenon. At any given time, around one in five Americans – 60 million people – feel so isolated that it makes them seriously unhappy.

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

Employees cheer as the Dreamliner takes off for the first time

From The Daily Mail:

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 BBC News:

People blessed with youthful faces are more likely to live to a ripe old age than those who look more than their years, work shows.

Danish scientists say appearance alone can predict survival, after they studied 387 pairs of twins.

The researchers asked nurses, trainee teachers and peers to guess the age of the twins from mug shots.

Those rated younger-looking tended to outlive their older-looking sibling, the British Medical Journal reports.
