New science of metagenomics 'will transform modern microbiology'

...enomes of all the microbes found in a habitat, the natural environment of the organisms. Although the genomes are fragmented, new DNA sequencing technology and more powerful computers are allowing scientists to begin making sense of these metagenomic jigsaw puzzles. They can examine gene sequences from tho...

'Hidden-hero' microbes in soil, water may help naturally clean toxic sites

Fruit flies and global warming -- Some like it hot

...ihood to be caught at baits in field sites without natural resources as an estimate of fitness in Drosophila. The results showed that heat treated flies were much more often caught at the baits at very hot temperatures while control flies were more often caught at cooler temperatures, while there was an over...

Immunization rates hit record high in poor countries

Endangered shortnose sturgeon saved in Hudson River

...he 1970s, report Mark Bain, associate professor of natural resources at Cornell, and his colleagues in the online publication PLoS ONE. However, the shortnose sturgeon is still endangered in other rivers, Bain said, and will not necessarily be removed from the endangered species list by the U.S. government. ...

White blood cells of cancer-resistant mice overwhelm natural defenses of cancer cells

...innate immune system ?neutrophils, macrophages and natural killer cells ?all infiltrate the tumor site in a multi-pronged killing response. "Each cell type had independent killing activity against the cancer cells," the authors said, using different molecules. Macrophages, for instance, have to be in physi...

ASU researchers test antibacterial effects of healing clays

...ona State University. "People are interested in natural cures and I think that there is a lot of nature that we don't understand yet," Williams says. "What if we discover a mechanism for controlling microbes that had never been discovered before? It is these avenues, at the boundaries of scientific discov...

Salmon farms kill wild fish, study shows

...The primary sea lice hosts are adult salmon. Under natural conditions, the adults are far offshore when the juveniles are migrating out to sea. Fish farms put adult salmon in net pens along the migration routes. The result is a cloud of sea lice through which the juveniles must migrate. "It takes only one or...

Novel experiment documents evolution of genome in near-real time

...the theory of evolution and the related process of natural selection of individuals with traits that convey a selective survival advantage. "Opinion surveys indicate that many people don't believe that evolution occurs," said Herring, "but if the skeptics could witness evolution actually occurring, as we did...

Scientists crack rhino horn riddle

...The team examined the heads of rhinos that died of natural causes and were donated by The Wilds in Cumberland, Ohio, and the Phoenix Zoo. Researchers conducted CT scans on the horns at O'Bleness Memorial Hospital in Athens and found dense mineral deposits made of calcium and melanin in the middle. The ca...

Living view in animals shows how cells decide to make proteins

... animal, because cells behave differently in their natural environment versus an artificially created environment such as a laboratory tissue culture," Garcia-Blanco said. "The complexity of alternative splicing necessitates its visualization as the decisions are occurring, because taking a cell out of its c...

Stem cells engage in dialogue with the cells that regulate their futures
