Scratch no more: Gene for itch sensation discovered

...fessor of anesthesiology, psychiatry and molecular biology and pharmacology. "But itch research has lived in the shadow of pain research, and no one knew which gene was responsible for itching in the brain or in the spinal cord until now." In fact, Chen's team became interested in GRPR because they were loo...

Nicotine rush hinges on sugar in neurons

...ndmark accomplishment for the fields of structural biology and neuronal cell signaling.” Besides substance ...associate professor of molecular and computational biology at USC. Many existing theories, which do not consider sugar’s role, are probably incomplete, Chen ...

Soils offer new hope as carbon sink

...y on the red ferrosol soils of the trial. "Soil biology improved, the need for added fertiliser reduced and water holding capacity was raised," he said. The trials also measured gases given off from the soils and found significantly lower emissions of carbon dioxide and nitrous oxide (a greenhouse gas mo...

Hormone helps mice 'hibernate,' survive starvation

...,” said Dr. Steven Kliewer, professor of molecular biology and pharmacology at UT Southwestern and the study’s senior author. “We hope to manipulate this hormone-receptor signaling pathway to craft the next generation of drugs to combat human obesity and other conditions.” Mammals on the brink of starvati...

Pesticides choke pathway for nature to produce nitrogen for crops

...doctoral fellow under Joe Thornton, a professor of biology who focuses on phylogenomics and nuclear receptor genes. Fox and colleagues began detailing their findings in the journal Nature (2001) and Environmental Health Perspectives (2004), testing more than 50 chemicals, including pentachlorophenol (PCP)...

Researchers shed light on mechanism of action used by anti-cancer drug

...h and co-leader of the cancer center’s cancer cell biology program, VCU researchers identified a mechanism by which sorafenib inhibits protein translation, and which may be involved in reducing expression of pro-survival factors, such as Mcl-1, and other proteins. The findings were published online in the jo...

MU researchers to study the status of black bears in Missouri

Study investigates 'divorce' among Galapagos seabirds

...red the study with David J. Anderson, professor of biology at Wake Forest. The chance of successfully breeding probably improves as the pairs of birds get older and are together longer, as has been found in other birds. But, often the female seeks a divorce after a few breeding seasons. Since males sig...

Plants recognize their siblings, biologists discover

... plants” said Susan Dudley, associate professor of biology at McMaster University in Hamilton, Canada. “When plants share their pots, they get competitive and start growing more roots, which allows them to grab water and mineral nutrients before their neighbours get them. It appears, though, that they only d...

Fat fish put obesity on the hook

...This is one more example of how basic experimental biology – zoology physiology and genetics in this case – can be brought to bear on human problems.” According the U.S. Centers for Disease Control and Prevention, the prevalence of overweight and obesity have risen steadily over the past 30 years. Among...

The mouflons of the Kerguelen archipelago

...ears later, Renaud Kaeuffer, a doctoral student in biology at UQAM, supervised jointly by Denis Réale and Dominique Pontier of the Université Claude Bernard Lyon I in France, went to the Islands to study the impact of introduced cats on the bird populations. Noticing that the mouflon population appeared to b...

Genome of Clostridium botulinum reveals the background to world's deadliest toxin

...." Genome sequences can tell us a lot about the biology of the organism, but research into clostridia has been hampered by the lack of a good genetic system. Professor Nigel Minton, Professor of Applied Molecular Microbiology at The University of Nottingham, has developed new methods to knock out genes in...

Eavesdropping comes naturally to young song sparrows

..., lead author of the study and a UW psychology and biology professor. Scientists study song learning in songbirds in part because it has a number of parallels with human language learning, and Beecher thinks eavesdropping also could play a role in how infants learn language. Sparrows in the wild are thou...

New research shows sharks use their noses and bodies to locate smells

...ation for a smell," said Jelle Atema, professor of biology at Boston University and study co-author. The new study examined the contribution of the olfactory system, the lateral line, and vision in odor source detection and localization in the smooth dogfish shark. The results, which appear in the June 1 ...

Moths mimic sounds to survive

...s conducted by Jesse Barber, a doctoral student in biology at Wake Forest. William E. Conner, professor of biology at Wake Forest, co-authored the study. In response to the sonar that bats use to locate prey, the...

Protein enables discovery of quantum effect in photosynthesis

...hat's what Robert Blankenship, Ph.D., professor of biology and chemistry in Arts & Sciences at Washington University in St. Louis, did when he contributed a protein to a study performed by his collaborators at Lawrence Berkeley National Laboratory and the University of California at Berkeley. The protei...
