Carnegie Mellon scientists find key HIV protein makes cell membranes bend more easily

...protective barrier for the cell against intruders, yet also contain molecules to recognize and communicate with other cells or get nutrients. Cells also communicate with one another via small, membrane-bound vesicles that contain proteins or other molecular cargo. When delivering their goods, vesicles fr...

How to lose weight and not go hungry: HU researcher develops drug that mimics feeling of 'fullness'

...f people the world over suffer today from obesity, yet there is no “magic bullet” that has yet provided a universally accepted solution. However, a young researcher at the Hebrew University of Je...

Dirty snow may warm Arctic as much as greenhouse gases

.... “A one-third change in concentration is huge, yet the Earth has only warmed about .8 degrees because the effect is distributed globally,” Zender said. “A small amount of snow impurities in the Arctic have caused a significant temperature response there.” Previous studies have analyzed dirty snow’...

Largest synthetic gene ever built offers insights into anti-malarial drug resistance

...ng pH across two different membranes, but we don't yet know exactly how they are doing it," Roepe says. "Still, knowing the pH values can help pharmacologists and chemists redesign a molecule to take advantage of these changes."...

Pesticides choke pathway for nature to produce nitrogen for crops

... to utilize. Thus, she said, there is the need for yet more fertilizer. Other reasons, Fox said, have been poor soil quality due to overuse, which strips nutrients such as nitrogen and phosphorous from the soil, and to tillage, which interrupts root structures and disturbs the nitrogen-fixing bacteria...

In mice, drug protects against diabetes and atherosclerosis

...o were overweight and who consumed high-fat diets, yet remained healthy. Hotamisligil's team, in collaboration with HSPH Associate Professor Eric Rimm, found a mutation in the aP2 gene. Tissue tests revealed that many of the subjects had a variant of the aP2 gene that sharply reduced production of the aP...

Plastic that grows on trees

...ientists have discovered the most effective method yet to convert glucose, found in plants worldwide and nature’s most abundant sugar, to HFM, a chemical that can be broken into components for products now made from petroleum. It has been an elusive goal for the legion of chemists trying to pull it off:...

Mutating the entire genome

...2.5 percent of DNA in the human genetic blueprint, yet diseases can result not only from mutant genes, but from mutations of other DNA that controls genes. University of Utah researchers report in the journal Nature Genetics that they have developed a faster, less expensive technique for mutating those l...

...s it needs from other organisms, and we don't know yet what they are," she said. Her laboratory will test the D. ethenogenes strains under a variety of different conditions, such as exposing them to different chlorinated compounds one at a time, varying the environment or the nutrients supplied, and t...

Experimental gene therapy 'abolishes' arthritis pain and lessens joint damage

... months, Kyrkanides said. Early results, while not yet published, suggest that one serotype of the AAV vector they are working with will provide results comparable to FIV. Beyond the current study, Kyrkanides’ work has contributed to the emerging theory that pain is not a symptom of osteoarthritis, b...

A cherry on top: Tart cherries may alter heart/diabetes factors

New technique will produce a better chromosome map

...rosophila melanogaster, was sequenced in 2000, and yet its relationship to chromosome structure remains unclear. "Since we want to know what genes are involved in the development of different structures in living systems, this is the first structure to look at," Novikov said. "This is the starting po...

Gene mutation linked to cognition is found only in humans

...n and chimpanzee genomes vary by just 1.2 percent, yet there is a considerable difference in the mental and linguistic capabilities between the two species. A new study showed that a certain form of neuropsin, a protein that plays a role in learning and memory, is expressed only in the central nervous sy...

Automatic identification of protein's critical features from the structure

...estion seems to be related to fashion and glamour, yet a group of scientists from the Universidad Nacional Autonoma de Mexico and the Buck Institute in the USA, were able to address it, although motivated by other reasons than fashion. In biology, the capacity to establish the function of a molecule, p...

UCLA AIDS Institute researchers find a peptide that encourages HIV infection

...al structure allows it to protect against viruses, yet if you make the same peptide and place its amino acids in a reverse order, that lets the virus in," Lehrer said. "We would like to learn why it happens, but at the moment there's no explanation for this paradoxical result." Still, the findings see...
