Country's economy plays role in Internet file-sharing patterns
Peer-to-peer file sharing over the Internet is a popular alternative approach for people worldwide to get the digital content they want. But little is known about these users and systems because data is lacking. Now, in an unprecedented study of BitTorrent users, a Northwestern University research team has discovered two behavior patterns: most users are content specialists -- sharing music but not movies, for example; and users in countries with similar economies tend to download similar types of content.

Radio telescopes unravel mystery of nova gamma rays
Highly-detailed radio-telescope images have pinpointed the locations where a stellar explosion called a nova emitted gamma rays. The discovery revealed a probable mechanism for the gamma-ray emissions, which mystified astronomers when first observed in 2012.

A highway runs through it: Mountain lions in southern California face genetic decay
Cut off by freeways and human development, mountain lions in southern California are facing a severe loss of genetic diversity, according to a new study led by the University of California, Davis. Pumas in the Santa Ana Mountains display lower genetic diversity than those from nearly every other region in the state.

Back off: Female chimps stressed out by competing suitors
Being the center of attention can have its drawbacks. For female chimpanzees, being around too many rowdy males is disadvantageous when foraging for food, an effect that can ultimately interfere with her reproductive ability. These are some of the findings of an 11-year-long study of wild East African chimpanzees in Uganda, led by Melissa Emery Thompson of the University of New Mexico in the US. It is published in Springer's journal Behavioral Ecology and Sociobiology.

How female flies know when to say 'yes'
A fundamental question in neurobiology is how animals, including humans, make decisions. A new study publishing in PLOS Biology on Oct. 7 reveals how fruit fly females make a very important decision: to either accept or reject male courtship. This decision appears to be generated by a very small number of excitatory neurons that use acetylcholine as their neurotransmitter located in three brain regions. This study provides the framework to understand how decisions are generated.

Improving biology education: A numbers game
Math is increasingly important to understanding and investigating the world of biology because quantitative biology, computational biology, and computer-based modeling approaches have emerged as important modes of inquiry. But, says the University of Pittsburgh's Samuel Donovan, teaching methods haven't always kept pace with developments in the field.

A $470,350 award from the National Science Foundation will support research at Indiana University-Purdue University Indianapolis to gain a better understanding of how proteins form groups or clusters within cells in the living body. Abnormal protein grouping is known to be associated with cancer and with heart arrhythmias, but scant knowledge exists about how proteins group.

Trying to share our 'epic' moments may leave us feeling left out
We might love to reminisce and tell others about our extraordinary experiences -- that time we climbed Mt. Kilimanjaro, got to taste a rare wine, or ran into a celebrity on the street -- but new research suggests that sharing these extraordinary experiences may come at a social cost. The findings are published in Psychological Science, a journal of the Association for Psychological Science.

A new way to extract bone-making cells from fat tissue
By sorting human fat tissue cells by their expression of a certain gene, Brown University scientists were able to retrieve a high yield of cells that showed an especially strong propensity to make bone tissue. With more refinement, the method could improve the ability of surgeons to speed bone healing.

Making oxygen before life
About one-fifth of the Earth's atmosphere is oxygen, pumped out by green plants as a result of photosynthesis and used by most living things on the planet to keep our metabolisms running. UC Davis scientists have now shown that oxygen can be formed directly from carbon dioxide in the upper atmosphere, changing models of how the atmosphere evolved early in Earth's history.

Study: Big-headed ants grow bigger when faced with fierce competitors
The big-headed ant (Pheidole megacephala) is considered one of the world's worst invasive ant species. As the name implies, its colonies include soldier ants with disproportionately large heads. Their giant, muscle-bound noggins power their biting parts, the mandibles, which they use to attack other ants and cut up prey. In a new study, researchers report that big-headed ant colonies produce larger soldiers when they encounter other ants that know how to fight back
