Warbling whales speak a language all their own

...ate at the University of Massachusetts, Dartmouth, worked with Buck and Tyack to develop a computer program to break down the elements of the whale's song and assign an abstract symbol to each of those elements. Suzuki wanted to see if he could design a computer program that enabled scientists to classify t...

Rutgers researchers find fat gene

...st's version of fat loss," Carman said. The group worked out the sequence of the amino acids that make up the PAP enzyme, allowing them to backtrack along the path to its origin ?the gene that coded it ?linking the enzyme to the yeast gene PAH1 that made it. Carman and his group went on to confirm the link...

Wisconsin scientists find a way to make human collagen in the lab

...agen to molecules of a specified size remain to be worked out, according to Raines. ...

Team discovers possible 'universal strategy' to combat addiction

...sciences, Mental Health and Addiction. Zhang, who worked with colleagues at the U of S, University of Toronto, and Vanderbilt University in Tennessee on the project, explains that VTA brain cells are sensitive to serotonin, a hormone associated with learning, sleep and mood. The team discovered that PTEN a...

Scientists seek to unwrap the sweet mystery of the sugar coat on bacteria

...ugars coat the bacteria. The microarray technique worked fast enough that the researchers were able to see the sugar coating change over time in the neonatal meningitis strain of E. coli. "Over time, the lectins lost their ability to see these bacteria," says Mahal. "This demonstrates that our system is a...

Tool developed to silence genes in specific tissues using RNAi

...his research team demonstrated how well their tool worked by silencing the WT1 tumor suppressor gene in the testes of mice. They found this gene is important in the production of healthy sperm by encoding a regulatory protein called a transcription factor that controls the formation of adherens junctions, o...

Genomics-based vaccine could prevent deadly cattle disease

...biology. But for Nene, who was born in Kenya and worked at ILRI for 15 years before coming to TIGR in 2001, the march against East Coast fever is significant reward, itself. "This disease takes an enormous toll on the local society and economy of rural areas across eastern and central Africa, including Ma...

Movement of chromosome in nucleus visualized

...present in the nucleus, nobody really knew if they worked together," said de Lanerolle. "There has been tantalizing evidence of organization in the nucleus--active genes found in the central region associated with nucleus complexes of transcription machinery necessary for gene expression, while inactive g...

Polymer aids in blood clotting, pointing way to new treatment

...e Peter Rohloff, an Illinois M.D./Ph.D student who worked in Docampo's former lab in the U. of I. College of Veterinary Medicine, Morrissey's postdoctoral assistants Stephanie A. Smith and Nicola J. Mutch, and Deepak Baskar, a graduate student in Morrissey's lab. ...

Georgia Tech accelerates drug discovery with new IBM supercomputing cluster

...the well-being of people everywhere." BellSouth worked closely with Georgia Tech and IBM to design a unique, reliable hosting environment to support the high power density supercomputing cluster. "With our hosting background, we had the flexibility and experience to quickly create a one-of-a-kind soluti...

Two NIH initiatives launch intensive efforts to find roots of common diseases

...tion to the project. A similar arrangement will be worked out with Affymetrix. Federally funded genotyping for GEI will be managed by an NIH coordinating committee under the usual government rules, subject to competition between research facilities, and begin in FY 2007. The research will lead directly to...

Plant-derived vaccines safeguard against deadly plague

...enter for Infectious Disease and Vaccinology. They worked out a new plant-based system to rapidly and stably produce high levels of proteins, called antigens, which conferred immunity against the plague. "This current work represents a new direction in our research because we've come to the realization th...

Strawberries by design

... Tech, commented: "Over the years, scientists have worked hard to find a system that would enable the efficient transformation of strawberry. However, these efforts have fallen short of the requirements to support large-scale studies of gene function in fruit crops." He added: "What sets this work apart is ...

Zebra finches remember songs dad sang

...' acquisition of speech." Vicario, Phan and Pytte worked with zebra finches, tiny songbirds native to Australia and favored by researchers because they breed well in captivity and all year- round. There are other animals that also learn vocalizations by imitating members of their species ?whales, dolphins ...

Computer simulation hints at new HIV drug target

...or wild-type enzyme, against which the drugs still worked well, and the drug-resistant double-mutant strain. Perryman used a computer simulation program called AMBER that performs several different types of calculations. The x-ray crystal structure of the molecule is used as the input, and the various moti...

...lling, according to Moore, who has for six summers worked with sockeye salmon through the UW's Alaska Salmon Program. Using counts of spawning sockeye for the last 50 years and previously measured nest sizes, Moore calculates that every summer the sockeye disturb at least 30 percent of the stream beds of tw...

U-M researchers take new approach to defeating Gram-negative bugs

...d the black plague. Woodard and his collaborators worked on E. coli in part because it is one of the more common Gram-negative bacteria, and it is considered by researchers the gold standard of Gram-negative bacteria. After their genetic modifications, E. coli was killed with just a fraction of the antibi...

Study: Paramedics save more lives when they don't follow the rules

...PR as directed by international guidelines has not worked well is because it is designed for two entirely different conditions: cardiac arrest and respiratory arrest," said Dr. Ewy. "What is good for one may not be good for the other. Cardiocerebral Resuscitation is designed for cardiac arrest. Sudden un...

Berkeley researchers lay groundwork for cell version of DNA chip

... could be coated with single-stranded DNA, Chandra worked with Douglas to demonstrate that this adhesion system could be used to attach cells to a non-biological surface. Douglas is a student under Mathies, director of UCB's Center for Analytical Biotechnology. Chandra and Douglas used a commercial chemica...
