Like human civilizations, bee so...

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

...form of kidney cancer in adults. It was originally developed as an inhibitor of the oncogene, Raf, which is frequently mutated in numerous cancers, including leukemia. Oncogenes are typically responsible for promoting tumor growth. Previous findings by Grant’s team, reported in the Journal of Biologic Chemi...

University of Pittsburgh School of Medicine researchers develop 'off-the-shelf' vascular grafts

...cine, University of Pittsburgh School of Medicine, developed its vascular graft by “bulk seeding,” or spraying, MDSCs inside a biodegradable porous, tubular polyester urethane scaffold using a rotational vacuum seeding device. After culturing their vascular constructs for seven days, the investigators then...

UCF nanoparticle offers promise for treating glaucoma

...ng Sanku Mallik, of North Dakota State University, developed the research on using nanoparticles as a delivery mechanism for the compound after supervising a student summer project at UCF. Duke University undergraduate Serge Reshetnikov spent a summer studying nanoscience on UCF’s Orlando campus as part of a R...

Electric fish conduct electric duets in aquatic courtship

... with lower frequency "creaks." The researchers developed custom software that offers new techniques for separating and documenting electrical pulses based on sex. They video recorded four pair of mating mormyrids (a feat in itself, since the species rarely breeds successfully in captivity) and identified n...

Male circumcision overstated as prevention tool against AIDS

...s infected and working as prostitutes while in the developed world typically this percentage of infected prostitutes is less than .1%. If these 7% of infected prostitutes in Africa sleep with five men in a week that means they are subjecting 35% of the country’s male population to the virus weekly. The virus i...

Modified mushrooms may yield human drugs

...ngenta Biotechnology Inc. research scientist, have developed a technique to genetically modify Agaricus bisporus -- the button variety of mushroom, which is the predominant edible species worldwide. One application of their technology is the use of transgenic mushrooms as factories for producing therapeutic pr...

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

... Microbiology at The University of Nottingham, has developed new methods to knock out genes in clostridia. "...C. botulinum," Professor Minton explains. "We have developed a highly efficient system, the ClosTron, with which we have, in a few months, knocked out over 30 ge...

'Smart' mice teach scientists about learning process, brain disorders

...he mice were adults. This technique, only recently developed and called conditional knockout, allows much more sophisticated experiments than traditional knockout, which entirely eliminates the gene. "Being able to turn a gene off throughout a brain is a really advanced thing to do," Dr. Bibb said. "It’s be...

Mule deer moms rescue other fawns

...fe than do mule deer fawns." Mule deer may have developed a more effective aggressive defence because they rely on fighting to protect themselves against predators year-round, while whitetails and many other species restrict aggressive defence to just the youngest fawns. Whitetails rely on flight rather tha...

During a two-week NASA-funded exploration led by Bill Stone of Stone Aerospace, the Deep Phreatic Thermal Explorer (DEPTHX) revealed that the geothermal sinkhole, or cenote, did not have a tunnel o...

Lessons from the orangutans: Upright walking may have begun in the trees

...ng between the high canopy and the ground and thus developed knuckle-walking for crossing from one tree to another on the ground. "Our conclusion is that arboreal bipedalism had very strong adaptive benefits. So, we don't need to explain how our ancestors could have gone from being quadrupedal to being bipe...
