Smooth sailing: 'cruise ship virus' tackled by UH, Baylor College of Medicine

...acation nightmare through the creation of a quick, accurate test for the "Cruise Ship Virus." One of the difficulties in treating Norwalk is that it is very hard to diagnose with traditional methods. "The current tests take a long time," Ruchhoeft said. "If we can build a diagnostic tool that mimics som...

'Sticky' mice lead to discovery of new cause of neurodegenerative disease

... of the 20 amino acids used to build proteins, and accurate loading is critical for the resulting protein to have the correct structure. Ackerman said that when the team began its studies, it did not expect that such a fundamental defect in protein synthesis could be behind the neurodegeneration they had o...

Bacteria can help predict ocean change

...be, according to a new study that may lead to more accurate models of ocean change. Scientists have long endorsed the concept of a unique biological niche for most animals and plants ?a shark, for example, has a different role than a dolphin. Bacteria instead have been relegated to an also-ran world of "f...

Brighter future for giant panda?

...d profiles DNA from panda faeces to provide a more accurate population profile. Professor Bruford said: "Our results found that previous surveys underestimated the population by more than 50%. These finding indicate that the species has a much better chance of long-term viability, although we must not becom...

H5N1 vaccine could be basis for life-saving stockpile

...t because ferrets are known to be an excellent and accurate model of influenza infection and immune response in humans," said Elena Govorkova, Ph.D., a staff scientist in the Department of Infectious Diseases at St. Jude. "Restricting the infection to the upper respiratory tract is important since in humans t...

Structure determined for p53 tumor suppressor protein as bound to DNA for anti-cancer activity

... dimer to DNA and used the structure to produce an accurate model of the p53 tetramer bound to DNA. "The bottom line is that we now have a detailed picture of how p53 binds DNA," says Ronen Marmorstein, Ph.D., a professor in the Gene Expression and Regulation Program at Wistar and senior author on the study...

When it comes to gene transcription, random pauses aren’t quite so random, study finds

...te beams of infrared light. "Our measurements are accurate to one-tenth of a nanometer--the width of a single hydrogen atom," Block explained. "When you study an RNAP enzyme at that scale, you discover that it moves along the DNA for a while, and then for no apparent reason it appears to stop. Some pauses we...

Stimulation of the semicircular canals can artificially control human walking and balance

...ar canal nerves afforded "remote control" that was accurate enough to keep subjects on pathways and avoiding obstacles while walking blindfolded through botanical gardens. The researchers also found that with a subject's head in another position, exactly the same stimulus could be used to disturb upright bala...

What controls stickiness of 'smart' chromosomal glue

...lled centromeric "stickiness" is essential for the accurate segregation of sister chromatids into separate cells. "The key question we wanted to explore was how this step-wise loss of cohesins in meiosis was regulated," said Amon. "It could be that the enzyme separase was the key regulatory player, or it co...
