Science's Breakthrough of the Year: Watching evolution in action

...corded on 27 December 2004, may be the result of a short gamma ray burst -- a rapid merger of two ancient neutron stars or a neutron star and a black hole. Brain Wiring and Disease: Several studies in 2005 suggest that diseases such schizophrenia, Tourette syndrome, and dyslexia are rooted in "faulty wir...

Stroke treatment a step closer after trial

...irst few critical hours through an infusion over a short period of time, perhaps as little as three days. Dr Tyrrell, who is based at Hope Hospital in Salford, added: "Stroke is a devastating condition that affects many thousand of people so the development of any effective treatment would have enormous b...

Multiple genes permit closely related fish species to mix and match their color vision

... color vision can undergo change over a relatively short period of evolutionary time. The work is reported by James K. Bowmaker of University College London, Karen L. Carleton of the University of New Hampshire, and their colleagues. Cichlid fish of the East African Rift Lakes are renowned for their dive...

'Perception' gene tracked humanity's evolution, scientists say

...ded humanity's separation from the other apes is a short one. Genes controlling the development of the brain almost always turn out to be identical or nearly so in chimpanzees and human beings. And as it turns out, the protein prodynorphin is identical in humans and chimps. It's the prodynorphin gene's p...

Penicillin, amoxicillin: Step aside for strep throat treatment

...atment given to 11,426 children showed that even a short course of the newer drugs is more effective than the traditional 10-day dose of the older antibiotics. Pediatricians at the University of Rochester Medical Center found that 25 percent of children treated for strep throat with penicillin ended up ba...

Gene Expression in the Aging Brain

... the aging process, can accumulate over relatively short stretches of evolutionary time. These results raise a number of questions about age-related gene expression changes, including whether metabolically active non-brain tissues display similar patterns of changes, and whether the divergence between hum...

Navigating the brain for sense of direction as paradigm for higher cognitive functions

... the aging process, can accumulate over relatively short stretches of evolutionary time. These results raise a number of questions about age-related gene expression changes, including whether metabolically active non-brain tissues display similar patterns of changes, and whether the divergence between hum...

Carnegie Mellon scientists create PNA molecule with potential to build nanodevices

These results raise a number of questions about age-related gene expression changes, including whether metabolically active non-brain tissues display similar patterns of changes, and whether the divergence between hum...

Marathon of nano-sprinters

...can only 'grab' onto the filament for a relatively short time, on the order of one second. During this time, a single motor covers about one micrometer, which represents only a tiny fraction, about 1/10000, of the long transport distances for cargo particles in axons. In other words, a single motor behaves...

Wild Gorillas Handy with a Stick

...avior in the wild. The sighting was published as a short note by Harry Beatty in the Journal of Mammalogy (recounted by primatologist Frans de Waal in The Ape and the Sushi Master). After spotting a shell mound, Beatty saw a chimp “come ambling round a bend bearing an armful of dried palm nuts,?sit down b...

New brain scan technology could save babies' lives

... is placed on the baby's head. The sources produce short flashes and the detectors measure the amount of light that reaches them through the brain and the time the light takes to travel. A software package also developed with EPSRC funding uses this information to build up a 3D image. This can show which p...

Greasing interferon's gears may pave way to greater therapeutic benefits, fewer side effects

... find advantages to increasing Stat1 action in the short term using drug treatments." Such therapies could allow physicians to turn up the effect of interferon temporarily to treat infections or other disorders and then to turn it back down to normal levels when the patient is cured. "The potential for...

Tuberculosis still a risk for patients receiving HIV drugs

...ion and of developing active tuberculosis within a short time, usually six months to one year," Dr. Girardi said. Since TB is a potentially deadly opportunistic infection for patients with HIV, doctors need to be aware of the risk and take certain precautionary measures. "HIV-infected patients, even when...

Fossil find: 'Godzilla' crocodile had head of a dinosaur, fins like a fish

...id. “But this croc was just the opposite. It had a short snout, and large teeth with serrated edges. It was definitely a predator of large sea creatures.?/p> Paleontologists Zulma Gasparini and Luis Spalletti of the National University of La Plata in Argentina uncovered the crocodile's fossil bones in ...

UCLA discovery will aid in treatment of patients with a deadly brain cancer

... are much more toxic and less beneficial. With the short survival times associated with glioblastoma, that is critical." Between 8,000 and 10,000 new cases of glioblastoma will be diagnosed in Americans this year. Average survival is less than a year, according to the American Cancer Society. Although tre...

Twin molecular scissors link creation of microRNAs with gene-silencing

RISC then unzips the two single-stranded miRNAs from each other and identifies and holds one as a guide to help it find the specific messenger RNA to be inactivated. Using complemen...

Targeted drug delivery achieved with nanoparticle-aptamer bioconjugates

...Nucleic acid ligands (referred to as aptamers) are short DNA or RNA fragments that can bind to target antigens with high specificity and affinity; analogous to monoclonal antibodies. In the field of cancer nanotechnology, aptamers have the potential to act as targeting molecules - directing the delivery of...
