Bright nearby double star Fomalhaut is actually a triple

Posted: 03 Oct 2013 05:50 PM PDT

The nearby star system Fomalhaut -- of special interest for its unusual exoplanet and dusty debris disk -- has been discovered to be not just a double star, as astronomers had thought, but one of the widest triple stars known.

Physicists 'entangle' microscopic drum's beat with electrical signals

Posted: 03 Oct 2013 11:26 AM PDT

Extending evidence of quantum behavior farther into the large-scale world of everyday life, physicists have "entangled" -- linked the properties of -- a microscopic mechanical drum with electrical signals.

Chemistry with sorted molecules: Reaction rate of many molecules depends on their shape

Posted: 03 Oct 2013 11:26 AM PDT

Most molecules occur in several shapes, which may behave very differently. Using a sorting machine for molecules, chemists can now for the first time directly measure the various reaction rates of different forms of the same compound.

Sieving through 'junk' DNA reveals disease-causing genetic mutations

Posted: 03 Oct 2013 11:23 AM PDT

Scientists have revealed nearly 100 genetic variants implicated in the development of cancers such as breast cancer and prostate cancer. The new method designed by the team identified these variants in the under-explored regions of DNA that do not code for proteins, but instead influence activity of other genes. As even more whole genome sequences become available, this approach can be applied to find any potential disease-causing variant in the non-coding regions of the genome.

3-D dynamic imaging of soft materials

Posted: 03 Oct 2013 10:22 AM PDT

Through a combination of transmission electron microscopy and ta unique graphene liquid cell, researchers have recorded the three-dimensional motion of DNA connected to gold nanocrystals, the first reported use of TEM for 3D dynamic imaging of soft materials.

Nothin' to sneeze at: New treatment for common allergies

Posted: 03 Oct 2013 08:11 AM PDT

Researchers have successfully tested treatments for people with allergies to grasses and to dust mites. The treatments are from a new class of therapy, known as 'synthetic peptide immuno-regulatory epitopes', or SPIREs. Positive results, first with a cat allergy therapy and now with house dust mite and grass allergy treatments, suggest that this approach may be used for many common allergies.

Certain type of fat could help humans lose weight

After studying genetically modified mice, the discovery of a fat that could help people lose weight could lead to supplements and a diet regime that will increase metabolism and decrease muscle fatigue in humans.
