Logging changed ecological balance for monkeys, damaged health

... University of Illinois at Urbana-Champaign. "When you see infection characteristics like these, they can be associated with very detrimental effects on the host." Since the logging period of the late 1960s, red-tailed guenons have been appearing in much lower densities, he said. What once were large g...

Beyond genes: Lipid helps cell wall protein fold into proper shape

...ther 40 percent are loosely tied to membranes. "So you are looking at possibly 70 percent of biology occurring at or in a lipid membrane surface," Dowhan said. Membranes and their surface proteins are accessible targets for pharmaceuticals, and most drugs target either membrane proteins on human cells o...

Study identifies gene in mice that may control risk-taking behavior in humans

Seaweed could make junk food healthier

...the food they do eat. With a burger, for example, you would simply remove some of the fat and replace it with the seaweed extract, which is an entirely natural product from a sustainable resource. You'd have a healthier burger and it's unlikely to taste any different. "This compound can also be added ...

MicroRNA tweaks protein that controls early heart development

...protein is a master regulator, and in its absence, you don't get any expansion of the heart ventricle at all. The finding that this microRNA controls Hand2, and probably several other proteins, is very significant." The UT Southwestern research team is currently screening human patients with congenital ...

Energy management in cells may hold key to cancer defense

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

...r can reduce the risk of bites and scratches. "If you look at free-ranging monkeys in Singapore's nature reserves, you see that feeding by visitors is not allowed, and it is actively discouraged," says Gregory Engel, an...

Quantum dots provide a faster, more sensitive method for detecting respiratory viral infections

...rrent detection tests take up to five days to tell you if a virus is present and another day or so to tell you which virus it is." Crowe lists three potential benefits for such an early detection system. It can...

Researchers predict infinite genomes

...sociated with a given species. How many genomes do you need to fully describe a bacterial species?" In pursuit of that question, TIGR scientist Hervé Tettelin and colleagues published a study in this week's (September 19-23) early online edition of the Proceedings of the National Academy of Scien...

Rodent social behavior encoded in junk DNA

...t to form pair bonds and nurture their young. "If you think of brain circuits as locked rooms, the vasopressin receptor as a lock on the door, and vasopressin as the key that fits it, only those circuits that have the receptors can be 'opened' or influenced by the hormone," added Hammock. "An animal's r...

Research suggests fitness of Florida panthers improved by limited breeding with Texas animals

...ll," he said. "They die in very high numbers. Once you get new blood, those defects disappear from the population. Hybrids are better than inbred animals." The paper also notes that "hybrid cats are beginning to expand their ranges to areas previously thought to be unsuitable," meaning environments "onc...

New bioinformatics technique for systematically analyzing key regions in DNA that help control gene activity

...ogist in Livermore's Biosciences Directorate. "But you can identify their binding sites in a promoter or regulatory region - there are usually a few of these for each gene. We wanted to see if we could somehow deduce how many transcription factors at a time, or combinations of factors, are coming togethe...
