Chemists identify key gene in development of type 1 diabetes

...n failed to develop diabetes compared to mice that possessed the gene, according to the investigators. Although it's likely that multiple genes are involved in the formation of diabetes, the finding provides proof of concept that efforts to block the formation of this particular protein is a promising approach...

Towards precise classification of cancers based on robust gene functional expression profiles

K-State researchers study gene regulation in insects

...n and discovered other insects, as well as humans, possessed the genes. But they wondered if the genes functioned the same in every organism. "We figured that it would be good to start with another insect -- but an insect that looks very different," Brown said. "A fruit fly has a very specific shape and a bee...

Scaled-down genome may power up E. coli's ability in lab, industry

'Banana-jawed' fossil mammal linked to rare sound-producing skill

...ls had the inflated jaws. This meant the trait was possessed by only one sex -- but which one? Previous research, he said, suggested such jaw structures likely were found in females. The researchers then analyzed incisor teeth, located in the front of the jaw and used for biting. In modern hyraxes, males have...

Birds that make teeth

...ed millions of years after the last known ancestor possessed them. Birds do not have teeth. However, their ancestors did--about 70?0 million years ago. The evolutionary loss of teeth corresponded to the formation of the beak that is present in all living birds. Nonetheless, it has been known that if mouse to...

A clue from macaques yields evidence for impaired retroviral defense genes in humans

...s gene was discovered because the version of TRIM5 possessed by rhesus macaques allows them to resist HIV infection, whereas the human version does not. Instead, the human version appears to respond to evolutionarily older viruses that are related to now-extinct viruses that are resident in the human genome. ...

Face perception is modulated by sexual orientation

...e University of Zurich. Of all the visual skills possessed by humans, face recognition is arguably the most developed. Past brain imaging studies have shown that the brain's cortical network for face perception includes regions in visual cortex that process the identification of individuals as well as social...

ASU researchers find link between social behavior, maternal traits in bees

...des their differing collecting habits, the strains possessed various other physiological and sense-related traits, but researchers did not understand how these suites of traits emerged. In 2004, Page came to ASU as director of the School of Life Sciences. Amdam followed him to ASU in 2005. Together, Amdam an...

Researchers link two more genes to sudden infant death syndrome

...ular autopsy. In each study, two of the 135 cases possessed mutations in either CAV3 or RyR2. SIDS -- the sudden, unexplained death of an infant under 1 year old -- is estimated to cause 2,500 infant deaths each year. "Combined with our previous discoveries, we now estimate that defects in genes that provid...

Diabetes hits 275 Australians each day as pandemic spreads

...rmation on diabetes and its consequences than that possessed by almost any other nation. "It also gives every Australian a clear indication of the increased risk they face of developing diabetes and its appalling complications if they do not make lifestyle changes," he said. The first stage of the AusDiab st...

Scientists identify a gene that may suppress colorectal cancer

...e tract—the harbingers of cancer. When these mice possessed one copy of the mutated gene, the incidence of small intestinal and colon polyps were reduced by about 90%. “This gene may give us a novel target to aid in the diagnosis, prevention, and/or treatment of cancer,?says Dr. Arthur Buchberg, one of the c...

The origin of the brain lies in a worm

...estor called Urbilateria. If this ancestor already possessed a nervous system, what it might have looked like and how it gave rise to the diversity of nervous systems seen in animals today is what Detlev Arendt and his group study at EMBL. To do so, they investigate the nervous system of a marine annelid worm ...

Shedding new light on proteorhodopsin

...acteria. The discovery implied that such bacteria possessed phototrophic as well as respiratory capabilities. This would be a critical adaptation for seafaring microbes because the world's oceans are permeated with "dead zones," areas that lack sufficient oxygen to sustain life. Subsequent studies establis...

Spud origin controversy solved

... scientists found that the Canary Island landraces possessed both Andean and Chilean types, as well as possible hybrids of the two. “In combination with other historical, molecular, agronomic, and crossing data, these findings support a hypothesis of multiple early introductions of both Andean and Chilean g...
