No single explanation for biodiversity in Madagascar
No single 'one-size-fits-all' model can explain how biodiversity hotspots come to be, finds a study of more than 700 species of reptiles and amphibians in Madagascar. By analyzing the distribution of Madagascar's lizards, snakes, frogs and tortoises, researchers find that each group responded differently to environmental fluctuations on the island over time. The results are important because they suggest that climate change and deforestation in Madagascar will have varying effects on different species.

NSF awards $300,000 to MU to research open online communities
Open online communities, such as Wikipedia or free and open source software development projects, have emerged as significant drivers of innovation, economic activity and social well-being. The National Science Foundation has awarded $300,000 to the University of Missouri Informatics Institute in the College of Engineering to develop principles, systems and detailed methodological approaches for sharing OOC data and explaining OOC research results across disciplines.

Unstoppable magnetoresistance
Researchers at Princeton University have discovered a material (WTe2) with an extremely large magnetoresistance, which is the change in resistance as a material is exposed to stronger magnetic fields. The researchers exposed WTe2 to a 60-tesla magnetic field, close to the strongest magnetic field mankind can create, and observed a magnetoresistance of 13 million percent. The material's magnetoresistance displayed unlimited growth, making it the only known material without a saturation point.

Snakes and snake-like robots show how sidewinders conquer sandy slopes
The amazing ability of sidewinder snakes to quickly climb sandy slopes was once something biologists only vaguely understood and roboticists only dreamed of replicating. By studying the snakes in a unique bed of inclined sand and using a snake-like robot to test ideas spawned by observing the real animals, both biologists and roboticists have now gained long-sought insights.

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.

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.

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.
