Modeling the restless brain

... how slow 5- to 10-second fluctuations of activity emerge naturally from much faster, chaotic neural interactions that typically last only a few milliseconds. "Our model suggests that the cortical resting state is not time-invariant, but instead contains rich and interrelated temporal structure at multi...

Puzzling plankton yield secrets to role in evolution/global photosynthesis

...dwelling phytoplankton from the genus Ostreococcus emerge at the primitive root of the green plant lineage, dating back nearly 1.5 billion years. Today, these microscopic, free-living creatures, among the smallest eukaryotes ever characterized, barely a micron in diameter, contribute to a significant share...

WHO data confirms low level of resistance to Tamiflu

...tion, there is a theoretical risk that a virus may emerge with decreased sensitivity to a drug. The Neuraminidase Inhibitor Susceptibility Network undertook screening for susceptibility to oseltamivir of influenza viruses randomly submitted to the national WHO Collaborating Centre for Reference and Researc...

Researchers publish first marsupial genome sequence

...round the genome." Other important findings to emerge from the analysis of the opossum genome include: The opossum has many genes involved in immunity, challenging the notion that marsupials possess only primitive immune systems. The opossum genome has an unusual structure with fewer chromoso...

MIT's ocean model captures diversity of underwater forests

...f the model. "The fact that the phytoplankton that emerge in our model are analogous to the real phytoplankton gives us confidence in the value of our approach." One of Follows' collaborators, Penny Chisholm, the Lee and Geraldine Martin Professor of Civil and Environmental Engineering and Biology and di...

NT researchers discover breakthrough in malaria treatment

...ern with such a policy is that the resistance will emerge quickly to the long acting drug. However the team believes that by combining the two drugs will help to prevent this from happening. ...

New antibacterials being developed to tackle MRSA superbug

...ation should be extremely low if a new drug was to emerge from this programme. "The antibiotic that we are developing is far more selective than those currently in use, targeting only staphylococcal infections," says Dr Lloyd Czaplewski, Director of Research at Prolysis. "Other, broad-spectrum antibiotics...

Whitefly spreads emerging plant viruses

...ust, new species of plant viruses will continue to emerge and cause damaging diseases in food and fiber crops," Brown said. Early virus and vector detection, information about their distribution and host range, and knowledge about the mode of virus transmission by this whitefly are essential for managin...

UCLA: How does your brain respond when you think about gambling or taking risks?

...t important behavioral model of decision-making to emerge in the past 50 years, whose components include the asymmetry between how losses and gains are valued," Fox said. Sabrina Tom, a UCLA research assistant in psychology and lead author of the study, said the people who have the most deactivation in t...

American scientist's research of life's first cells

...tion. "The cell, as an evolutionary unit, could emerge from replicating molecules through very simple physical mechanisms," said Chen. "This work suggests that evolving higher levels of biological organization might have been surprisingly easy during the origin of life." Born in San Diego, California,...

Embryonic patterning makes the feathers fly

...In the controls, rudimentary feather bud epithelia emerge by cell rearrangements and coordinated cell shape elongation. In inhibitor-treated explant epithelia, cells remain cobblestone shaped and randomly arranged. While the chicken feather movie poses no threat to Hollywood, the researchers say that wa...

T for two: Scientists show how immune system chooses best way to fight infection

...determining whether a maturing T cell is likely to emerge from the thymus as an effector cell or a regulatory cell. The research suggests that new treatments could be developed to deliberately affect the type of T cells produced, allowing scientists to tackle a number of diseases which are influenced by the...

For crickets, parasitic flies can stop the music

...ans within the cricket while they grow. After they emerge from the dying cricket, they pupate and metamorphose into mature flies. Brockmann and co-author Manuel Vélez, a former UF student who earned his doctorate in 2004, hypothesized that the presence of flies would affect how male crickets sing and how...

"We must take immediate actions to protect habitat and stop ...

Sunflower speciation highlights roles for transposable elements in evolution

...on, but also suggest that the sunflower system may emerge as an excellent model group for studying the natural forces influencing the activation and proliferation of transposable elements in plants. This is because in addition to their hybrid origins, each of the three hybrid species is adapted to, and evol...

Genetic 'roadmap' charts links between drugs and human disease

...ing signatures. One of the surprising results to emerge from the Connectivity Map involves gedunin, a plant derivative that, despite a long history of medicinal use, is not well understood molecularly. The researchers identified gedunin in a high-throughput chemical screen for molecules that disrupt hormo...
