The early cost of HIV

8/29/2014
Researchers at UC Davis have made some surprising discoveries about the body's initial responses to HIV infection. Studying simian immunodeficiency virus (SIV), the team found that specialized cells in the intestine called Paneth cells are early responders to viral invasion and are the source of gut inflammation by producing a cytokine called interleukin-1 beta (IL-1β). Though aimed... [Comments]

Factor in naked mole rat's cells enhances protein integrity

8/29/2014
SAN ANTONIO (Aug. 29, 2014) Scientists at the Barshop Institute for Longevity and Aging Studies, part of the School of Medicine at the UT Health Science Center at San Antonio, have found another secret of longevity in the tissues of the longest-lived rodent, the naked mole rat. They re... [Comments]Factor in naked mole rat's cells enhances protein integrity

New research reveals how wild rabbits were genetically transformed into tame rabbits

8/29/2014
MISSOULA Until recently, little has been known about what genetic changes transform wild animals into domesticated ones. An international team of scientists, one of whom is a University of Montana assistant professor, has made a breakthrough by showing that genes controlling the development of the brain and the nervous system were particularly important for rabbit domestication. The study w... [Comments]

Leading Ebola researcher at UTMB says there's an effective treatment for Ebola

8/29/2014
A leading U.S. Ebola researcher from the University of Texas Medical Branch at Galveston has gone on record stating that a blend of three monoclonal antibodies can completely protect monkeys against a lethal dose of Ebola virus up to 5 days after infection, at a time when the disease is severe. Thomas Geisbert, professor of microbiology and immunology, has written an editorial for Nature... [Comments]

CCNY team defines new biodiversity metric

8/29/2014
To understand how the repeated climatic shifts over the last 120,000 years may have influenced today's patterns of genetic diversity, a team of researchers led by City College of New York biologist Dr. Ana Carnaval developed a new biodiversity metric called "phylogeographic endemism." It quantifies the degree to which the genetic variation within species is restricted in geographical space... [Comments]

Assortativity signatures of transcription factor networks contribute to robustness

8/29/2014
Dartmouth researchers explored the type and number of connections in transcription factor networks (TFNs) to evaluate the role assortativity plays on robustness in a study published in PLOS Computational Biology in August. The study found that the assortativity signature contributes to a network's resilience against mutations. "In simulations, it seems that varying the out-out assortati... [Comments]

Hydrogen powers important nitrogen-transforming bacteria

8/29/2014
This news release is available in German . Nitrite-oxidizing bacteria are key players in the natural nitrogen cycle on Earth and in biological wastewater treatment plants. For decades, these specialist bacteria were thought to depend on nitrite as their source of energy. An internati... [Comments]Hydrogen powers important nitrogen-transforming bacteria

Ready for mating at the right time

8/29/2014
This news release is available in German . The exchange of chemical signals between organisms is considered the oldest form of communication. Acting as messenger molecules, pheromones regulate social interactions between conspecifics, for example, the sexual attraction between males... [Comments]Ready for mating at the right time

Not all phytoplankton in the ocean need to take their vitamins

8/29/2014
Some species of marine phytoplankton, such as the prolific bloomer Emiliania huxleyi , can grow without consuming vitamin B1 (thiamine), researchers have discovered. The finding contradicts the common view that E. huxleyi and many other eukaryotic microbes depend on scarce supplies of t... [Comments]Not all phytoplankton in the ocean need to take their vitamins

'K-to-M' histone mutations: How repressing the repressors may drive tissue-specific cancers

8/29/2014
Kansas City, MO. - In a cell's nucleus, chromosomal DNA is tightly bound to structural proteins known as histones, an amalgam biologists call chromatin. Until about two decades ago, histones were regarded as a nuclear "sidekick," the mere packing material around which the glamorous DNA stran...
