...akers develop plans and strategies to conserve the diversity of life in this unique region." Since 1990, RAP scientists have discovered hundreds of new plant and animal species, and RAP data have contributed to the creation of several national parks throughout the world. CI's RAP program deploys expert team...

Primate virus jumps species barrier to humans for first time in Asia

... work on the topic in Asia, which has huge primate diversity and large human populations." Jones-Engel and her co-authors also argue for more research on diverse contexts of human-primate contact. The vast majority of previous viral transmission research focused on bushmeat hunting and consumption, a practice...

Survival of heart patients on beta-blockers varies greatly with genetic variation

...ll benefit from the larger sample size and greater diversity of patients," Spertus says. "It's really an exciting and unique collaborative venture that builds a strong relationship between researchers in Kansas City and St. Louis." The TRIUMPH registry recruits patients through the Cardiovascular Outcomes Res...

Enlisting genomics to understand flu evolution

...ations. These results suggest that "the potential diversity is greater than we thought," says Lipman. "We need to have more comprehensive information on the entire genome [and] enough samples from around the world," he adds, to find the benign virus strain that will become next season's scourge. The more geno...

ORNL, UC Berkeley unravel real-world clues to Earth's mysteries

...ly used artificially cultivated organisms lack the diversity found in nature, so potentially critical community and environmental interactions go unsampled. Raymond Orbach, director of DOE's Office of Science, noted that this research offers a glimpse of what will be possible in the near future. "This work il...

Chickadees can help humans get their bearings

MicroRNAs play a big part in gene regulation - and evolution

...at some microRNAs could be involved in shaping the diversity of life," says lead author Nikolaus Rajewsky. The information will be a vital tool for the microRNA research community, providing opportunities to test predicted biological functions of microRNAs and to explore their evolutionary significance. ### ...

Ancient DNA helps clarify the origins of two extinct New World horse species

...sue is that we showed the apparent lack of species diversity in North American horses in the Late Pleistocene - as horses are a poster child of evolution," says Cooper. To explore the origins of the horses, the authors examined mitochondrial DNA (mtDNA) extracted from fossilized horse bones. Mitochondria, whi...
