Olfactory system detects pheromones that control reproduction

...and Lynn W. Enquist published their findings in an immediate early publication on November 10, 2005, in the journal Cell. Yoon and Dulac are at Harvard University, and Enquist is at Princeton University. Related studies by HHMI investigator Linda B. Buck are published in the same issue. The pheromone communic...

Cancer support cells may evolve, fuel tumor growth, study shows

.... 16) issue of the journal Cell.While not offering immediate application to the treatment of human cancers, the research indicates that new anti-tumor therapies may be more effective if their targets are broadened to include molecules within supporting cells of the cancer.These additional target cells are in t...

Grid bridges 4,800 miles for molecular repositories

...nment, national security and energy. "There is an immediate scientific need for the BioSimGrid," affirmed T. P. Straatsma, lead researcher at PNNL. "It will enable molecular scientists to collaborate in a far more sophisticated way than we've been able to ever before. The ramifications of sharing terascale da...

The dangerous legacy of lead

...earch, as scientists shift their emphasis from the immediate public health threat to understanding the long-term burden on the body, said Michael McCabe Jr., Ph.D., associate professor of Environmental Medicine at the University of Rochester. "We know more about lead than any other environmental agent, but we...

Membrane research opens window to benefits for plants, humans

...volved a tandem of basic-science firsts that offer immediate real world applications, the scientists say. First, Swedish plant biochemists and crystallographers at Lund University and Chalmers University of Technology, studying membrane proteins of spinach, solved the structure of a water-protein channel -- a...

First big influenza genome study reveals flu evolution

...in public databases, such as GenBank, which allows immediate access to the scientific community. The new study represents the initial results from the Influenza Genome Sequencing Project, launched in 2004 by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of ...

Science's Breakthrough of the Year: Watching evolution in action

...g of the 1918 pandemic flu virus could have a more immediate impact on medicine. The amazing story of flu genes preserved in permafrost and painstakingly reconstructed has a chilling coda: the deadly flu seems to have started out as purely a bird virus. Understanding the evolution of last century's deadly bird...

Seaweed yields new compounds with pharmaceutical potential

Pulp mill devastates swans' sanctuary in Chile

...ling upon the Chilean government and CELCO to take immediate remedial measures to protect the sanctuary and develop a plan to end pollution from the mill. Further research is also urgently needed to determine the full impact of the pollution on both the environment and human health. A growing citizen's moveme...

Sudden change in social status triggers genetic response in male fish, study finds

...social ladder, the egr-1genes in his brain send an immediate signal to the gonadotropin-releasing hormones cells to start growing. As these cells get bigger, they crank out more and more hormones, transforming the male from doormat to dominant within 10 minutes. In fact, laboratory analysis confirmed that ...

Grabbing addiction by the tail

... displayed no sensitized behavior. "The effect was immediate and very noticeable," said Wang. There are several types of glutamate receptors involved in memory and learning, but because the artificial peptide specifically targets only the deleterious internalization process of addiction-affected neurons, and...

Beach pollution is worst during new and full moon

...o with the season of the year. The results are of immediate practical use to swimmers and beach managers alike, according to Boehm. "The general public can use the phase of the moon and the tide stage to assess the relative risk of illness," she says. "It is riskier to swim during spring-ebb tides [receding t...

Study provides insight into cellular defenses against genetic mutation

...ond its role in screening out faulty mRNAs through immediate decay, we have also learned that the NMD factor Upf1 is part of a related process that regulates the expression of many normal genes by controlling the timeframe in which their encoded mRNAs decay. Evolution often borrows a useful mechanism from one ...

Environment, not genes, key in family relationships

...ies." "While these findings in themselves have no immediate practical implication," he continued. "But they should help guide future research into the important question of how children's genes help shape family interaction systems." ...

Genomics researchers discover protein deficit that causes drug toxicity

...l detects the misfolded proteins and tags them for immediate destruction or quarantines them in a "cellular trash can" known as an aggresome (last syllable rhymes with "foam"). Whether destroyed or aggregated into the aggresome, the effect is the same: the patient's body suffers a protein deficit that disrupts...

Stem cells bring fast direct improvement, without differentiation, in acute renal failure

Furthermore, "these beneficial effects are predominantly mediated, as our data suggest, by paracrine rather than t...

Scientists uncover new clues about brain function in human behavior

...t have any people or faces in them and thus had no immediate social component. In remarkable contrast to the response to faces, the amygdala response to threatening scenes was abnormally increased in participants with Williams Syndrome (see graphic below), mirroring their severe non-social anxiety.
