Amino Acids In Nectar Enhance Butterfly Fecundity: A Long Awaited Link
The fascinating interactions between flowers and their pollinators have resulted in a spectacular diversity of plants. In order to entice pollinators such as bees, flies or butterflies to visit and successfully pollinate their flowers, plants have evolved intriguing mechanisms and attractants, of which nectar is best known. [Ironic] LONDON: A jailed cocaine dealer is working as Santa Claus on
John Tams, who dons beard, boots and red suit to work in a cafe's Christmas grotto, said he wanted to give something back to the community... Brain's Messengers Could Be Regulated, Study Suggests
Tiny, spontaneous releases of the brain's primary chemical messengers can be regulated, potentially giving scientists unprecedented control over how the brain is wired. The work could lead to a better understanding of neurological diseases like schizophrenia. Sputtering electrical activity -- like a firecracker's leftover sparks after a big bang -- was long considered inconsequential background noise compared with the main cell-to-cell interactions underlying thought and memory. But researchers found that the miniscule events that follow a burst of electrical and chemical activity among neurons are far more important that previously thought. Top 10 Gadgets of the Year
Near-vaporware keyboards, gaming towers, little laptops, terrific tablets and a hacked iProduct are the gadget champs of 2007. Antivirals Effectively Curb Influenza Virus, Analysis Finds
Two antiviral drugs, oseltamivir and zanamivir, are highly effective when given as a preventive measure to reduce the spread of the influenza virus, according to an analysis of household-based studies by researchers at Fred Hutchinson Cancer Research Center, University of Michigan and University of Virginia, published in the current print edition of the American Journal of Epidemiology. The analysis also suggests that treatment with oseltamivir may reduce the infectiousness of influenza patients, although further studies are needed to provide a definitive conclusion. Scientists Learn More About How Roughage Keeps You 'Regular'
If you ever wondered just how a high-fiber diet helps keep you, well, "regular,"scientists may have the answer. Their results suggest that as these bulky foods make their way down the gastrointestinal tract, they run into cells, tearing them and freeing lubricating mucus within. [Stupid] Children banned from wearing scary outfits
A nursery has banned ghost costumes from its Halloween party. Supercomputing By Reservation Puts Petaflops At Researchers'Fingertips
Supercomputers keep growing ever faster, racing along at the blazing speed of nearly one petaflops -- 10 to the fifteenth, or one thousand trillion calculations per second -- equivalent to around 250 thousand of today's laptops. In contrast, the experience of a computational scientist can be anything but fast -- waiting hours or days in a queue for a job to run and yield precious results needed for further steps. The unpredictably of queues can impede the course of research, slowing progress with unexpected periods of waiting. Imaging Experts Perform MRI Cardiac Scans By Remote Control
UCLA radiologists and Siemens Medical Solutions have developed remote-control software that enables an off-site imaging expert to operate a magnetic resonance imaging (MRI) machine via the Internet. Reported in the November issue of Radiology, the study found that the quality of the remote scans were superior to onsite scans by a less experienced technologist, suggesting options for helping facilities or regions with limited medical staff and expertise. Gut Research Yields New Anti-cancer Approach
Researchers believe they have discovered by chance a new way to fight colorectal cancer, and potentially cancers of the esophagus, liver and skin. Early work shows that a group of compounds called peroxisome proliferator-activated receptor-gamma (PPARgamma) inhibitors may act through some of the same mechanisms as the blockbuster chemotherapy Taxol, but with key differences.
