Trapping Sunlight With Silicon Nanowires

Berkeley Lab researchers have found a better way to trap light
in photovoltaic cells through the use of vertical arrays of silicon nanowires. This could substantially cut the costs of solar electric power by reducing the quantity and quality of silicon needed for efficient solar panels.

New Evidence Hints at Global Glaciation 716.5 Million Years Ago
Thu, 11 Mar 2010 06:53:00 -0600
Geologists have found evidence
that sea ice extended to the equator 716.5 million years ago, bringing new precision to a "snowball Earth" event long suspected to have taken place around that time. The new findings--based on an analysis of ancient tropical rocks that are now found in remote northwestern Canada--bolster the theory that our planet has, at times in the past, been ice-covered at all latitudes.

A section of the Arctic Ocean seafloor that holds vast
stores of frozen methane is showing signs of instability and widespread venting of the powerful greenhouse gas, according to the findings of an international research team led by University of Alaska, Fairbanks, scientists Natalia Shakhova and Igor Semiletov.

Loss of Enzyme Reduces Neural Activity in Angelman Syndrome
Thu, 11 Mar 2010 06:54:00 -0600
Angelman syndrome (AS) is a debilitating neurological disorder characterized by mental retardation and a high frequency of autism. Researchers have now found that the gene mutation underlying AS appears to affect the ability of neurons to communicate and to properly develop during the first few years of life, a time when brain activity is "rewired" by external stimuli.

Oldest Measurement of Earth's Magnetic Field Reveals Battle Between Sun and Earth for Our Atmosphere

Scientists at the University of Rochester have discovered that the Earth's magnetic field 3.5 billion years ago was only half as strong as it is today, and that this weakness, coupled with a strong wind of energetic particles from the young sun, likely stripped water from the early Earth's atmosphere.

Most polymers--materials made of
long, chain-like molecules--are very good insulators for both heat and electricity. But an MIT team has found a way to transform the most widely used polymer, polyethylene, into a material that conducts heat just as well as most metals, yet remains an electrical insulator.

The barnacle, a key thread in the marine food
web, was thought to be missing along rocky coasts dominated by upwelling. Now a research team headed by Brown University marine ecologist Jon Witman has found the opposite to be true: barnacle populations thrive in vertical upwelling zones in moderately deep waters in the Galapagos Islands. The findings appear in Ecological Monographs.

Until now,
paleontologists have generally believed that the closest relatives of dinosaurs possibly looked a little smaller in size, walked on two legs and were carnivorous. However, a research team including Randall Irmis, curator of paleontology at the Utah Museum of Natural History and assistant professor in the department of geology and geophysics at the University of Utah, has made a recent discovery to dispel this hypothesis.
