Innovative collaboration brings Arctic science into the classroom

... are already proving to be highly valuable, as her high frequency samples have captured temporal variability that otherwise would have been missed. Because of Anya's interest, in May and June 2004, Holmes, Clapp, and Alexander Zhulidov, a Russian scientist who had been on the Lena trip, visited her schoo...

Nature provides inspiration for important new adhesive

...t's abundantly produced in the U.S. and has a very high content of protein," Li said. Soy protein is inexpensive and renewable, but it lacks the unique amino acid with phenolic hydroxyl groups that provide adhesive properties. Li's research group was able to add these amino acids to soy protein, and make ...

Hydrogen and methane provide raw energy for life at 'Lost City'

...nisms that heavily blanket some black smokers. The high diversity revealed itself only after a 2003 expedition when the biology team led by Woods Hole Oceanographic Institution's Timothy Shank analyzed water samples "vacuumed" from around the vents. "There aren't a lot of each kind of animal, most are on...

Mother birds increase progesterone to hatch females

...irst meiosis. They injected either a low dose or a high dose of progesterone (dissolved in sesame oil) or ...to the control group rate of 63 percent males. The high dose of progesterone, however, produced only 25 percent males. "Thus, we think that how much proges...

Future diabetes drugs may target new protein interaction

These early results suggest that we are on to a promising new treatment strategy that could potentially help us improve treatment for patients with recurrent glioblastoma." Achieving the 36 percent regr...

WHO suspends Marburg work, appeals for new funds

...fever and its frequent fatality are resulting in a high level of fear, which is further aggravated by a lack of public understanding of the disease. Moreover, because the disease has no cure, hospitalization is not associated with a favourable outcome, and confidence in the medical care system has been er...

Building a protein name dictionary from full text: a machine learning term extraction approach

...named entities in full text. The approach collects high frequency terms in an article, and uses support vector machines (SVM) to identify biological entity names. It is also computationally efficient and robust to noise commonly found in full text material. We use the method to create a protein name dicti...

Butterfly migration could be largest known

...r fewer numbers. This year, however, exceptionally high winter rainfall in southern California has created a bumper crop of plants for the caterpillars to eat, fuelling a population boom, Shapiro said. The butterflies take about three days to reach the Central Valley, and the current generation will fly ...

Bee mites suppress bee immunity, open door for viruses and bacteria

... mite-infested bees rapidly increased to extremely high levels when the bee was exposed to the bacteria. The virus levels in mite-free bees did not change when the bee was injected with bacteria. One chemical, GOX or glucose oxidase, is put into the honey by worker bees and sterilizes the honey and all t...

Scientists analyze chromosomes 2 and 4

The sequencing work on the chromosomes was carried out as part of the Human Genome Project at Washington University; Broad Institute of MIT, Cambridge, Mass.; Stanford DNA Sequencing and Technology ...

Nanobacteria in clouds could spread disease, scientists claim

...rom the ground by winds, could transit between the high humidity region of the clouds and the relatively dry inter-cloud regions, leading to oscillations between a dormant state and one of activation," explained Professor Wickramasinghe. "Remnants of a sticky protein (slime) coating nanobacteria makes the...

Penn Researchers Use Robotic Surgery

An (ecological) origin of species for tropical reef fish

...s an extreme of life's capacity for variation. Yet high biodiversity in tropical seas foil evolutionists' attempts to explain the splitting of one species into two on the basis of geographical barriers. According to standard evolutionary theory proposed by Dobzhansky and Mayr more than 50 years ago, mount...

Chemical Engineer Kao Explores Antibiotic Synthesis With DNA Chips

...ons. "In one year we should be able to generate a high producer that's equivalent to 20 years of work with the traditional method, and then we can study the identifiable mutations," Kao said. Whether she's studying existing mutants or creating her own, Kao's main interest lies in learning how to manipul...
