Sounds During Sleep Aid Memory, Study Finds

From The New York Times:

Science has never given much credence to claims that you can learn French or Chinese by having the instruction CDs play while you sleep. If any learning happens that way, most scientists say, the language lesson is probably waking the sleeper up, not causing nouns and verbs to seep into a sound-asleep mind.

But a new study about a different kind of audio approach during sleep gives insight into how the sleeping brain works, and might eventually come in handy to people studying a language, cramming for a test or memorizing lines in a play.

Are The Earth's Oceans Hitting Their Carbon Cap?

Remi Benali / Corbis

From Time Magazine:

Like the vast forests of the world, which continually suck carbon dioxide from the atmosphere and release oxygen, the planet's oceans serve as vital carbon sinks. Last year the oceans absorbed as much as 2.3 billion tons of carbon, or about one-fourth of all manmade carbon emissions. Without the action of the oceans, the CO2 we emit into the atmosphere would have flame-broiled the planet by now.

From Live Science:

Jim White is a professor of Geological Sciences and the Director of the Environmental Studies Program at the University of Colorado at Boulder, and is leading research being conducted on the Greenland ice sheet. White is also the director of The Institute of Arctic and Alpine Research (INSTAAR), which focuses on studying the effects of environmental changes in high altitude and high latitude regions. White's research on the Greenland ice sheet is part of the North Greenland Eemian Ice Drilling (NEEM) project. Fourteen nations are collaborating in the NEEM research, with the common goal of obtaining samples of core ice from the Eemian Period, which was the last interglacial period, about 120,000 years ago. The samples will help researchers interpret the atmospheric environment present during the Eemian period, and relate those interpretations to the present day atmosphere. The ultimate goal of this research is to learn more about how the Earth's climate functions, and what, if anything, can be done to counteract any adverse environmental conditions. The core ice samples will also help researchers identify the causes behind the Earth's increased warming, including those driven by human activity. Below, White answers the ScienceLives 10 Questions.

Antarctic Temperature Spike Surprises Climate Researchers

Photo: Is Antarctica more sensitive to global warming that we thought? Getty

From Nature:

Polar region was unexpectedly warm between ice ages.

During the warm periods between recent ice ages, temperatures in Antarctica reached substantially higher levels than scientists had previously thought. This conclusion, based on ice-core studies, implies that East Antarctica is more sensitive than it seemed to global warming.

Previous estimates suggested that peak temperatures during the warmest interglacial periods — which occurred at around 125,000, 240,000 and 340,000 years ago — were about three degrees higher than they are today. But a team led by Louise Sime of the British Antarctic Survey in Cambridge, UK, concludes that Antarctica was actually around six degrees warmer.

The Military Is Looking For A 25-Year Battery

Photo: Nuclear power: The package inside this prototype betavoltaic battery contains layers of silicon carbide and metal foil embedded with the radioactive isotope tritium. When high-energy electrons emitted by the decay of tritium hit the silicon carbide, it produces an electrical current that exits the cell through the metal pins. Such batteries are designed to last 25 years. Credit: Widetronix

From Technology Review:

Long-lived nuclear batteries powered by hydrogen isotopes are in testing for military applications.

Batteries that harvest energy from the nuclear decay of isotopes can produce very low levels of current and last for decades without needing to be replaced. A new version of the batteries, called betavoltaics, is being developed by an Ithaca, NY-based company and tested by Lockheed Martin. The batteries could potentially power electrical circuits that protect military planes and missiles from tampering by destroying information stored in the systems, or by sending out a warning signal to a military center. The batteries are expected to last for 25 years. The company, called Widetronix, is also working with medical-device makers to develop batteries that could last decades for implantable medical devices.

The British Museum does not agree — at least not yet. But never underestimate Dr. Hawass when it comes to this sort of custody dispute. He has prevailed so often in getting pieces returned to what he calls their “motherland” that museum curators are scrambling to appease him.

From Science Daily:

Science Daily (Nov. 16, 2009) — Physicists at the National Institute of Standards and Technology (NIST) have demonstrated the first "universal" programmable quantum information processor able to run any program allowed by quantum mechanics -- the rules governing the submicroscopic world -- using two quantum bits (qubits) of information. The processor could be a module in a future quantum computer, which theoretically could solve some important problems that are intractable today.

Attractiveness Based Partly on Skin Color

Participants in the study changed the skin color of the faces in images (right), making the skin redder, yellower and brighter (from top to bottom), saying those looked healthier than faces that are less red, less yellow and less bright (left).

From Live Science:

When it comes to an attractive face, color can make all the difference, suggests a new study.

The research focused on facial skin color among Caucasians, finding a light, yellowish complexion looks the healthiest. The skin color could indicate a healthy diet of fruits and vegetables, whose pigments are known to change the skin's hue, researchers suggest.

(The researchers predict the results would hold for other ethnicities as well.)
