A team of scientists has found a novel road-block in the pain pathway, which could be used to treat chronic pain. Their results are published March 13 in the online, open-access journal PLoS Biology. Pain is an important physiological function that protects our bodies from harm. Pain-sensing nerves transduce harmful stimuli into electrical signals and transmit this information to the brain via the spinal cord. However, when these nerves get activated persistently, such as after injury or...

Do bacteria, like higher organisms, have a built-in program that tells them when to die? The process of apoptosis, or cell death, is an important part of normal animal development. In a new study published March 6 in the online, open-access journal PLoS Biology, Hanna Engelberg-Kulka and colleagues (at Hadassah Medical School of the Hebrew University, Jerusalem, Israel) have described for the first time a novel cell death pathway in bacteria that is similar to apoptosis in higher organisms....

Scientists have found that the gut endoderm has a significant role in propagating the information that determines whether organs develop in the stereotypical left-right pattern. Their findings are published 6 March 2012 in the online, open-access journal PLoS Biology. Superficially, we appear bilaterally symmetrical. Nonetheless, the stereotypical placement of our organs reveals a stereotypical internal asymmetry. For example, the heart is located on the left, while the liver is located on...

Some disease-causing parasites are known to favor one sex over the other in their host species, and such differences between the sexes have generally been attributed to differences in immune responses or behavior. But in a new article, published February 28 in the magazine section of the online, open-access journal PLoS Biology, David Duneau from Cornell University and Dieter Ebert from the University of Basel now propose that all sorts of characteristics that differ between the sexes of the...

The ability to detect and respond to magnetic fields is not usually associated with living things. Yet some organisms, including some bacteria and various migratory animals, do respond to magnetic fields. In migratory animals like fish, birds, and turtles, this behavior involves small magnetic particles in the nervous system. However, how these particles form and what they are actually doing is not fully understood. In a new study, published February 28 in the online, open-access journal...

There are a number of drugs and experimental conditions that can block cognitive function and impair learning and memory. However, scientists have recently shown that some drugs can actually improve cognitive function, which may have implications for our understanding of cognitive disorders such as Alzheimer's disease. The new research is reported 21 February in the open-access journal PLoS Biology. The study, led by Drs. Jose A. Esteban, Shira Knafo and Cesar Venero, is the result of...

The proteins actin, myosin and titin are big players in the business of muscle contraction. Scientists at the European Molecular Biology Laboratory (EMBL) in Hamburg, Germany, have now examined another muscle protein — myomesin — which they discovered can stretch up to two-and-a-half times its length, unfolding in a way that was previously unknown. The study is published 14 February in the open-access, online journal PLoS Biology. Myomesin links muscle filaments, which stretch...

Researchers Study Genetic History Of Sheep
2012-02-09 03:56:02

Mapping the ancestry of sheep over the past 11,000 years has revealed that our woolly friends are stars among domestic animals, boasting vast genetic diversity and substantial prospects for continued breeding to further boost wool and food production for a rising world population. An international research team has provided an unprecedented in-depth view of the genetic history of sheep, one of the world's most important livestock species. The study, published February 7 in the online,...

Image 1 - Device Could One Day Read Your Mind By Decoding Brain Waves

[ Watch the Video ] Have you ever imagined taking on the role of Spock in the popular Star Trek shows and films, using your mind melding abilities to read the thoughts of others. Well that could one day become a reality, in a roundabout way. Researchers at the University of California, Berkeley and University of California, San Francisco, have demonstrated a new method to reconstruct words, based on signals from the brains of patients thinking of those words. While it is a far cry from...

The many factors that contribute to how cells communicate and function at the most basic level are still not fully understood, but researchers at Baylor College of Medicine have uncovered a mechanism that helps explain how intracellular membranes fuse, and in the process, created a new physiological membrane fusion model. The findings appear in the current edition of the journal PLoS Biology. "Within our cells, we have communicating compartments called vesicles (a bubble-like membrane...

PLoS ONE is an open-access peer-reviewed scientific journal published by the Public Library of Science (PLoS). It was established in 2006 as a beta version. In August 2008 it moved from a weekly publication schedule to a daily one, publishing articles as soon as they became ready. In October 2008, it came out of “beta.” In September 2009, PLoS ONE made full online usage of every published article publicly available. The founding managing editor was Chris Surridge. He was succeeded by...
