The next time you have to make a difficult moral decision, you might think twice about mulling it over in the bath or shower.   New research in Psychological Science has found that the physical notion of cleanliness significantly reduces the severity of moral judgments showing that intuition, rather than deliberate reasoning, can influence our perception of what is right and wrong.

Lead researcher, Simone Schnall, University of Plymouth, explains the relevance of the findings to everyday life; “When we exercise moral judgment, we believe we are making a conscious, rational decision, but this research shows that we are subconsciously influenced by how clean or ‘pure’ we feel.

A new small satellite about the size of a loaf of bread and called Firefly is designed to help solve the mystery of the most powerful natural particle accelerator in Earth's atmosphere - TGFs, or terrestrial gamma-ray flashes - which likely result from thunderstorms.

The mission is the second project under the NSF CubeSat program. A CubeSat satellite consists of three cubes attached end to end in a rectangular shape.

Two of our galaxy's most massive stars, until recently shrouded in mystery, have been viewed by the Hubble Space Telescope, unveiling greater detail than ever before.
 
The image shows a pair of colossal stars, WR 25 and Tr16-244, located within the open cluster Trumpler 16. This cluster is embedded within the Carina Nebula, an immense cauldron of gas and dust that lies approximately 7500 light-years from Earth. The Carina Nebula contains several ultra-hot stars, including these two star systems and the famous blue star Eta Carinae, which has the highest luminosity yet confirmed.  

A new "barcode chip" developed by researchers at the California Institute of Technology (Caltech) promises to revolutionize diagnostic medical testing. In less than 10 minutes, and using just a pinprick's worth of blood, the chip can measure the concentrations of dozens of proteins, including those that herald the presence of diseases like cancer and heart disease. 

The device, known as the Integrated Blood-Barcode Chip, or IBBC, was developed by a group of Caltech researchers led by James R. Heath, the Elizabeth W. Gilloon Professor and professor of chemistry, along with postdoctoral scholar Rong Fan and graduate student Ophir Vermesh, and by Leroy Hood, president of the Institute for Systems Biology in Seattle, Washington. 

In 1970, a Japanese roboticist named Masahiro Mori described what he called the "uncanny valley" - a point on a graph relating human affinity for a machine to its likeness of humans themselves, where human affinity plummets as the likeness becomes nearly indistinguishable from ourselves. As robots become more humanlike, our fondness for them increases.

Researchers at the Mayo Clinic studying Parkinson’s disease have made a breakthrough therapy that could slow progression of the disease or even halt its onset.

Previous research has discovered that patients with Parkinson’s have an abnormal abundance of alpha-synuclein, a protein, which is believed to be the cause of the disease. Targeting this protein has since taken forefront of their studies and researchers have developed a method to reduce the expression of alpha-synuclein in the brain.

The Milagro collaboration, comprised of scientists from 16 institutions across the United States, has discovered two nearby regions with an unexpected excess of cosmic rays.   This is the second finding of a source of galactic cosmic rays relatively near Earth announced in the past week. In the November 20 issue of Nature, ATIC an international experiment led by LSU scientists announced finding an unexpected surplus of cosmic-ray electrons from an unidentified but relatively close source.

The global economic turmoil has started having an impact on the wind energy industry in Europe. Some companies are cutting down forecasts and production for 2009 and the market is showing the first signs of slowdown.

The current economic situation is slowly affecting the wind energy industry, remarks Frost Sullivan Research Analyst Gouri Nambudripad. "We are going to see a slowing down of the double-digit growth rates that were witnessed in the past few years.

Researchers at The Scripps Research Institute writing in Nature Structural&Molecular Biology say they have figured out how a macromolecular machine is able to unwind the long and twisted tangles of DNA within a cell's nucleus so that genetic information can be "read" and used to direct the synthesis of proteins, which have many specific functions in the body.

You've heard it before.   According to the laws of physics, bees can't fly.   Yet fly they do.   And British zoologist Sir James Gray noticed something strange about dolphins in 1936.  He had observed the sea mammals swimming at a swift rate of more than 20 miles per hour, but his studies had concluded that the muscles of dolphins simply weren't strong enough to support those kinds of speeds. The conundrum came to be known as "Gray's Paradox." 

For decades the puzzle prompted much attention, speculation, and conjecture in the scientific community. But now, armed with cutting-edge flow measurement technology, researchers at Rensselaer Polytechnic Institute have tackled the problem and conclusively solved Gray's Paradox.
