Institute for Systems Biology Symposium Addresses Need for Better Computational Tools

The Institute for Systems Biology announced today at its 2005 international symposium on Computational Challenges in Systems Biology that ISB's Human Proteome Folding Project launched on IBM's World Community Grid in November 2004 has already predicted 50,000 protein structures. . "This project showcases the enormous power of collaborations," stated Dr. Richard Bonneau, senior scientist at the In...

Virginia Tech, Nanjing Institute researchers discover half-billion year-old fossils

Scientists interested in ancient life have a wealth of fossils and impressions frozen in rocks that they can study from as far back as 540 million years ago ?when animals with shells and bones began to become plentiful. But evidence of complex life older than 540 million years is scant and difficult to study. . Now, a research team from Virginia Tech in the United States and Nanjing Institute of...

Asian immigrants in NYC not receiving HIV education at religious institutions

Religious institutions serving New York City's Asian immigrants are not educating their congregations about HIV prevention and healthcare, in part because some leaders hold stigma and fear about the disease, according to a new study by The New York Academy of Medicine in the upcoming issue of the international journal AIDS Education and Prevention. This special issue devoted to Asians/Pacific I...

UC San Diego partners with Venter Institute to build marine microbial genomics cyberinfrastructure

Researchers at the University of California, San Diego (UCSD) will build a state-of-the-art computational resource and develop software tools to decipher the genetic code of communities of microbial life in the world's oceans. . The new resource will help scientists understand how microbes function in their natural ecosystems, enable studies on the effect humans are having on the environment, as...

Weizmann Institute suggests that immune cells help to maintain cognition and brain cell renewal

A team of scientists at the Weizmann Institute of Science, led by Prof. Michal Schwartz of the Neurobiology Department, has come up with new findings that may have implications in delaying and slowing down cognitive deterioration in old age. The basis for these developments is Schwartz's team's observations, published today in the February issue of Nature Neuroscience, that immune cells contribut...

Virginia Bioinformatics Institutes launches microbial database

Researchers at the Virginia Bioinformatics Institute at Virginia Tech have launched a publicly-available microbial database to host a range of microbial genome sequences. . The VBI Microbial Database (VMD), which is described in a recent article published in Nucleic Acids Research (Vol.34, D379-D381), contains genome sequence and annotation data for the plant pathogens Phytophthora sojae and Phyt...

Weizmann Institute scientists discover a molecular security mechanism for keeping mutations in check

Everyone knows mutations ?genetic mistakes in DNA, the material of heredity ?are bad: The more mutations in the cell's DNA, the higher the risk of cancer developing. But in the last few years it has become clear that the very processes that generate mutations, if they take place at a relatively low frequency, can actually protect us from cancer. How does the body know how to keep these processes...

Radiologists attempt to solve mystery of Tut's demise

Egyptian radiologists who performed the first-ever computed tomography (CT) evaluation of King Tutankhamun’s mummy believe they have solved the mystery of how the ancient pharaoh died. The CT images and results of their study were presented today at the annual meeting of the Radiological Society of North America (RSNA). . Ashraf Selim, M.D., radiologist at Kasr Eleini Teaching Hospital, Cairo Uni...

Latest advances in DNA sequencing highlighted at DOE Joint Genome Institute User Meeting

Four hundred researchers tapping the massive flow of DNA sequence information will gather March 28-30 to share their recent developments at the 2nd Annual U.S. Department of Energy Joint Genome Institute (DOE JGI) User Meeting. DOE JGI is the world's only user facility dedicated to making high-throughput DNA sequencing available to a diverse research community and individual investigators who oth...

UCLA AIDS Institute researchers find a peptide that encourages HIV infection

UCLA AIDS Institute researchers have discovered that when a crucial portion of a peptide structure in monkeys that defends against viruses, bacteria and other foreign invaders is reversed, the peptide actually encourages infection with HIV. . .. "Although it may seem counterintuitive to value or even study a peptide that increases the ability of HIV-1 to enter a broad range of human cells...

Weizmann Institute scientists develop a general 'control switch' for protein activity

Our bodies could not maintain their existence without thousands of proteins performing myriad vital tasks within cells. Since malfunctioning proteins can cause disease, the study of protein structure and function can lead to the development of drugs and treatments for numerous disorders. For example, the discovery of insulin’s role in diabetes paved the way for the development of a treatment bas...
