Study Links Ebola Outbreaks To Animal Carcasses

...s were tested for the Ebola virus, with 14 samples being found positive. In 11 cases, instances of human infection were directly linked to gorilla, chimpanzee and duiker carcasses. To prevent future outbreaks from becoming health crises, health officials and wildlife researchers must continue to work toge...

New Technique for Tracking Gene Regulators

...t are located nearknown genes. Genes identified as being regulated by CREB using thismethod include the gene responsible for causing Huntington’s disease inmice, which is important for making advances in understandingHuntington’s disease in humans, and genes that may play an importantrole in certain cancer...

U-M scientist to talk about tissue engineering at AAAS

...ent therapies, too." These approaches are not yet being tested in humans, but Krebsbach said some small clinical trials are under consideration. If the combination therapy approach works, Krebsbach said the next step would be working with engineers to develop anatomically correct scaffolding with the sam...

Scientists seek answers on what activates deadly anthrax spores

...to drugs that block the process." The research is being paid for by a $152,687 grant from the Southeast Regional Center of Excellence in Biodefense and Emerging Infections, based at Duke University, one of eight such regional centers funded by the National Institute of Allergy and Infectious Diseases. Th...

Study finds more than one-third of human genome regulated by RNA

Gene therapy converts dead bone graft to new, living tissue

...he patient's own, as if the dead bone were a house being renovated by replacing a single brick at a time without tearing the whole structure apart. Schwarz's studies with mice showed their dead splints were quickly converted to new, healthy bone. He projects that the bone would be completely converted in ...

Female sex hormones play a vital role in defense against sexually transmitted diseases

...study, mice were treated with hormones but, before being exposed to the real herpes virus, they received a vaccine Surprisingly, unlike in the first study, the progesterone-treated mice and the mice that received no hormones were the most protected. About half the mice in the combination hormone group wer...

Experiments provide proof of how traveling in groups protects insects

... this new work appears to show is that even though being part of the band has its own costs -- such as greater competition for food and cannibalism of injured crickets ?overall, there's a clear benefit to band members," Lorch said. "Predation occurs anyway, but any given individual is far better protected ...

Protein Packages Found To Activate Genes; May Be What Regulates Development And Disease

... to control how we develop in the womb. Instead of being activated individually like most genes, the HOX genes appear to be turned on in groups by massive numbers of tags. HOX genes also are deeply involved in cancer, making the findings particularly important. Some of the proteins that regulate HOX genes...
