Genomics-based vaccine could prevent deadly cattle disease

... signal," a telltale peptide sequence found at the start of secreted proteins. Sure enough, the scientists found some 400 T. parva genes containing the secretion signal. This set of genes provided a starting pool of candidate proteins. Based on further tests, the study's research team, led by the Interna...

Sun protection for plants

Scientists discover a genetic switch that links animal growth and cancer

Supersized 'island' of resistance genes discovered in an infectious bacterium

...cted patients die. "Less than 2 years after the start of the French epidemic episode, we found the complete genome ID of the microbe involved and developed a better understanding of what to expect for the future, in terms of new antibiotic resistance," Claverie said. "This work will guide a future inte...

UCLA scientists uncover mechanism of response to targeted therapy

...ientists seeking a target for a new cancer therapy start work in cell lines andthen advance to laboratory animals to test their theories. Working backward from responsesin clinical trials is unusual, Thomas said. Responses observed in clinical studies led researchers back to the laboratory. Their laborator...

St. Jude projects 90 percent cure rate for ALL

That success is based to a large extent on the work done at St. Jude and elsewhere in identifying specific mutations in leukem...

First demonstration of 'teaching' in non-human animals

...e criteria and thus qualifies as teaching. At the start of a tandem run, the leader finds a naïve individual who is willing to follow her. But tandem runs are rather slow because the follower frequently pauses to look round for landmarks so that it can learn the route. Only when the follower has done this...

"They provide neurobiological evidence that helps explain human infants' acquisition of speech." Vicario, Phan and Pytte worked with zebra...

Often fueled by warm temperatures and a lack of circulation, this nutrient rush can cause algae blooms. When the algae dies, it sinks to the bott...

Enzyme crystal structure reveals 'unexpected' genome repair functions

...tivate XPB within the TFIIH complex to allow it to start the DNA unwinding process. "Even though TFIIH does not act directly in initial damage recognition, the interaction of XPB with the DNA lesion suggests that XPB plays a role in switching TFIIH from transcription mode to NER," Tainer says. "The struc...

Alaska seal pup diet may hold key to decline of population

...iet, Polasek said. A seal that weighed 26kg at the start of the study, on the high-fat diet, has also continued to grow in a similar manner. These results fit with a recent study by a team from Göteborg University that found wild seal pups smaller than 26 kg when they were weaned were less likely to survi...

COX-2 inhibitors significantly reduce risk of cancer

...fects, so we are not advising people to go out and start taking them until more studies confirm that they are safe and effective," says Harris. Celebrex is still widely used for pain relief, but Vioxx was pulled off the market in 2004 following reports of heightened risk of heart attacks. "It's clear tha...

Newman's team also further indicated that greenhouse gas-forced climate change will have only a small impact on the Antarctic stratosphere and recovery of the ozone hole. The upper ozone layer is important because it blocks 90-9...
