Brain's Energy Restored During Sleep (09/07/2010)

In the initial stages of sleep, energy levels increase dramatically in brain regions found to be active during waking hours, according to new research in the June 30 issue of the Journal of Neuroscience. These results suggest that a surge of cellular energy may replenish brain processes needed to function normally while awake.

'Quantum Computer' a Stage Closer With Silicon Breakthrough (24/06/2010)

The remarkable ability of an electron to exist in two places at once has been controlled in the most common electronic material -- silicon -- for the first time. The research findings -- published in Nature by a UK-Dutch team from the University of Surrey, UCL (University College) London, Heriot-Watt University in Edinburgh, and the FOM Institute for Plasma Physics near Utrecht -- marks a significant step towards the making of an affordable "quantum computer."

Astronomers Witness a Star Being Born (18/06/2010)

Astronomers have glimpsed what could be the youngest known star at the very moment it is being born. Not yet fully developed into a true star, the object is in the earliest stages of star formation and has just begun pulling in matter from a surrounding envelope of gas and dust, according to a new study that appears in the current issue of the Astrophysical Journal.

Tea and coffee 'protect against heart disease' (18/06/2010)

Drinking several cups of tea or coffee a day appears to protect against heart disease, a 13-year-long study from the Netherlands has found.

It adds to a growing body of evidence suggesting health benefits from the most popular hot drinks.

Those who drank more than six cups of tea a day cut their risk of heart disease by a third, the study of 40,000 people found.

FCC to toughen internet rules (18/06/2010)

The stage has been set for what many predict will be an ugly fight over broadband plans for US citizens.

The Federal Communications Commission has taken the first formal steps towards tougher rules for broadband.

It asked for public comment on three different plans, igniting an expensive lobbying campaign by all sides.

The looming battle follows a court ruling questioning the FCC's right to regulate internet service providers after one throttled traffic to users.

That court ruling dealt a major blow to a central plank of the FCC's broadband plan called net neutrality which demands that all data traffic be treated equally.

Wet past for red planet (18/06/2010)

Researchers say equal elevation of dry valleys and river deltas points to an ancient Martian ocean

Mars was once a water world, concludes a new study that dives into the controversy over whether an ocean covered much of the Red Planet’s northern hemisphere early in its history.

Ever since researchers found hints in the late 1980s that Mars’ northern lowlands are ringed by what appears to be a dried-up shoreline, planetary scientists have debated whether the region was covered by water about 3.5 billion years ago. Now, Gaetano Di Achille and Brian Hynek of the University of Colorado in Boulder have analyzed spacecraft data to find that 29 of 52 dry river deltas and thousands of river valleys within and surrounding the northern lowlands all lie at about the same elevation. That’s just what would be expected if a sea once blanketed the region, leaving behind a level coastline, the researchers report online June 13 in Nature Geoscience.

Saturn, Mars and Venus line up in June sky (10/06/2010)

As darkness falls at the beginning of June, three planets will form a long line in the western sky. Saturn will be at the upper left, Mars in the middle and Venus at the lower right. Venus will form a straight line with the bright stars Pollux and Castor of the the Twins on June 11 fairly low in the west-northwest. On June 19 and 20, the brilliant white planet will pass just north of the Beehive . Binoculars will show the twinkling while the planet gleams steadily.
To Venus's upper left (south) will be red-orange , making a colorful contrast with nearby blue-white Regulus, the brightest star of the the Lion. The colors will appear most vivid through binoculars. Mars and Regulus will be closest on June 6, but they will remain near each other for the first half of the month.

Could Life Survive on Mars? Yes, Expert Says (09/06/2010)

Researchers at McGill's department of natural resources, the National Research Council of Canada, the University of Toronto and the SETI Institute have discovered that methane-eating bacteria survive in a highly unique spring located on Axel Heiberg Island in Canada's extreme North. Dr. Lyle Whyte, McGill University microbiologist explains that the Lost Hammer spring supports microbial life, that the spring is similar to possible past or present springs on Mars, and that therefore they too could support life.

Is 3-D Vision Bad for You? (09/06/2010)

Two-dimensional entertainment is so 2009.

With Sony’s release of the 3-D upgrade for PlayStation 3, the upcoming 3-D Nintendo DS, at least two 3-D television channels on the horizon, and the box office success of a little flick called Avatar, the consensus is clear: The future of entertainment is 3-D.

But while moviegoers have flocked to recent 3-D offerings, film fans also have had mixed reviews about their experiences, with some reporting headaches, nausea, vision problems and motion sickness. And with 3-D leaping to the small screen, clinical researchers and tech experts want to know whether the special effect might damage eyes in the process.

Beam Me Up, Scotty! Scientists Teleport Info 10 Miles (09/06/2010)

We may never be able to teleport ourselves "Star Trek"-style, but scientists managed to transmit information a record distance using entangled photons.

Scotty won't beam anybody anywhere anytime soon, but a new report by Chinese scientists shows that it is possible to transmit information over long distances using quantum entanglement. The research, published in the current issue of the journal Nature Photonics, could lead to faster and smaller quantum-based computers and unbreakable, encrypted communication across the world.
