The 'heliosphere', the name given to the region of the sun's influence, may not have the comet-like shape predicted by existing models, say researchers.

As the solar wind flows from the sun, it carves out a bubble in the interstellar medium. Models of the boundary region between the heliosphere and interstellar medium have been based on the assumption that the relative flow of the interstellar medium and its collision with the solar wind dominate the interaction. This would create a foreshortened "nose" in the direction of the solar system's motion, and an elongated "tail" in the opposite direction. 
If you think choosing a candy bar or a granola bar is totally a matter of free will, think again. A new study published in the Journal of Consumer Research argues that the choices we make to indulge ourselves or exercise self-control depend on how the choices are presented.

University of Miami Assistant professor of marketing Juliano Laran tested subjects to determine how certain words and concepts affected their ability to control themselves when confronted with the choice of healthy or unhealthy food. He found that consumer choices were affected by the actions most recently suggested to them by certain key words.
For many years, so called 'junk RNA' was thought to be nothing more than cellular trash. Recent research, however, has called this view into question as scientists have discovered the importance of some small RNAs that generally contain more than 20 molecular units called nucleotides.
The Naval Research Laboratory's Ion Tiger has set an unofficial record for flight endurance by a hydrogen-powered fuel cell unmanned air vehicle, staying out for 23 hours and 17 minutes. The test flight took place on October 9th through 10th at Aberdeen Proving Ground. The Ion Tiger fuel cell development system team is led by NRL and includes Protonex Technology Corporation, the University of Hawaii, and HyperComp Engineering.

The electric fuel cell propulsion system onboard the Ion Tiger has the low noise and signature of a battery-powered UAV, while taking advantage of hydrogen, a high-energy fuel. Fuel cells create an electrical current when they convert hydrogen and oxygen into water, with only water and heat as byproducts.
Researchers from the University of Gothenburg say they have discovered a new cancer gene related to adenoid cystic carcinoma,  a slow-growing but deadly form of cancer. The research group can now show that the gene is found in 100% of these tumors, which means that a genetic test can easily be used to make a correct diagnosis.

The newly discovered cancer gene is what is known as a fusion gene, created when two healthy genes join together as a result of a chromosome change.
Parts of our genetic programs that determine programmed cell death in plants and animals are actually evolutionarily related and function in a similar way, according to an article in Nature Cell Biology.

Research has previously believed that animals and plants developed different genetic programs for cell death.
