Flocking together: Study shows how animal groups find their way

...ognized leaders or signaling system. The finding, published in the Feb. 3 issue of Nature, helps settle age-old questions about how animals coordinate their actions. Previously, scientists had looked for subtle signals or other explicit systems that animals may use in disseminating information through groups....

NIH Calls on Scientists to Speed Public Release of Research Publications

Low level of extinction during ice age linked to adaptability

... on the topic appears in the May issue of Geology, published by the Geological Society of America. "If the patterns I detected also are true for the modern ice age -- and other researchers' results suggest that they may be -- then modern marine life ought to be relatively resistant to extinction," he said. "Y...

Transgenic plants remove more selenium from polluted soil than wild plants, new tests show

...ning up polluted soil. The new research findings, published Feb. 1 in the journal Environmental Science and Technology, show that three transgenic lines of the Indian mustard plant, Brassica juncea, absorbed two to four times more selenium from contaminated soil than the genetically unaltered, wild-type plant...

50-year-old Mystery Solved: Protein Tags Regulate Key Ion Channel

... for the development of new drugs. The discovery, published in the 8 April 2005 issue of the journal Cell, answers a question dating back to the 1950s: How do cells control the background movement of potassium ions across the cell membrane? This process is important because the flow of potassium ions determin...

Researchers discover chemical compounds that affect plant growth

Fibril Shape Is The Basis Of Prion Strains And Cross-species Prion Infection

...pecies, Surewicz and colleagues found. In a study published last year in the journal Molecular Cell, Surewuicz and colleagues also demonstrated that a "preseeding" process between animals with different prion amino acid sequences could overcome species barriers. For instance, mouse prion fibrils normally infe...

McGill researchers shed light on formation of carcinogen in food

...ical in a wide range of food products. The study, published in the October, 2004 issue of Journal of Agricultural and Food Chemistry, shows how food-based amino acids and sugars break down when heated to produce furan. It also identifies other food components, such as vitamin C and polyunsaturated fatty acids...

HIV-1 spread through six transmission lines in the UK

... and subsequent transmission chains. The findings, published in the latest issue of the Proceedings of the National Academy of Sciences, also suggest that antiviral therapy has not had a significant impact on the growth of the epidemic and that changes in sexual behaviour have been more effective in slowing th...

Multi-purpose protein regulates new protein synthesis and immune cell development

...us erythematosus." Results from the study will be published in the Feb. 1 issue of the Journal of Clinical Investigation. Kaufman studies fundamental signaling pathways involved in the production of new proteins in the cell's endoplasmic reticulum (ER). The process begins with chains of amino acids, which ...

This discovery is an important step toward a complete mapping of which parts of the genome are required for embryonic development. The new findings also probe into how genetic networks are built and how they co...

New insight into regulation of blood stem cells

A research study published in the February issue of Developmental Cell expands on previous studies by using adult animals to examine the role of a key gene known to be required for blood cell formation. Information gained from this research will be useful for future studies ai...

Researchers rein in regulatory RNAs

Sense-antisense transcripts, or SATs, are pairs of RNA molecules generated from opposite DNA strands at the same locus. The number of SATs identified in the past several years has grown substantiall...
