Virginia Tech's System X supercomputer provides super tool for simulation of cell division

Virginia Tech researchers in computer science and biology have used the university's supercomputer, System X, to create models and algorithms that make it possible to simulate the cell cycle -- the processes leading to cell division. They have demonstrated that the new mathematical models and numerical algo...

ASU researchers test antibacterial effects of healing clays

... "Here we are bridging geology, microbiology, cell biology ?transdisciplinary sciences, exactly what (ASU President) Michael Crow has been promoting. A year ago, I'd look at the clay and say, 'well that's dirt.' Now I know a little something about clay structure; Lynda knows a little bit about microbiology. ...

By 2048 all current fish, seafood species projected to collapse

...m is an assistant professor of marine conservation biology at Dalhousie University, Halifax, Canada. In the paper "Impact of Biodiversity Loss on Ocean Ecosystem Services," an international team of ecologists and economists studied the role marine biodiversity plays in maintaining ecosystem services, which...

Cloned mice created from fully differentiated cells, a milestone in cloning research

...burgh School of Medicine and director of stem cell biology and co-leader of the cancer stem cell program at the University of Pittsburgh Cancer Institute. Previous attempts by scientists to produce animal clones directly from fully differentiated B cells, T cells and neurons had failed beyond the blastocyst...

Penn researcher shows that DNA gets kinky easily at the nanoscale

..., which explores how the fields of nanotechnology, biology and medicine all intersect. "The nanoscale just happens to also be the scale at which cell biology operates," Nelson said. "We're entering an era when we are able to use the tools of nanotechnology ...

One-of-a-kind imaging probe reveals secrets useful for drug discovery

...., an emeritus professor of chemistry and chemical biology at Cornell University, led landmark chemical studies of walking stick venom. He was pleased to know the insect was being studied in Florida. "We used not dozens but thousands of walking sticks to get enough secretions to do analyses and, no, it's no...

Invasive ants territorial when neighbors are not kin

...nia," said David Holway, an assistant professor of biology at UCSD and senior author on the study. "However, we found that while ants from the same supercolony do not fight, clashes between ants from different supercolonies occur commonly along territorial borders." The distance between nests did not play...

Evolution of Old World fruit flies on three continents mirrors climate change

...it," said Raymond Huey, a University of Washington biology professor who is co-author of a paper describing the findings, published Aug. 31 in Science Express, the online edition of the journal Science. The research deals with an Old World fruit fly species called Drosophila subobscura, which originally r...

Science researchers genetically transform immune cells into tumor fighters

...nberg says. "It's a lot of sophisticated molecular biology and most of our work is going into designing retroviruses, putting genes into cells efficiently and getting them expressed." ...

Discovery in the evolution of the immune system absorbing cells

...veness of the vaccine". The study of comparative biology remains an important source of scientific knowledge. Several years ago, the same researchers demonstrated the great versatility and power of the innate immune response of the complement system in lower vertebrates, whereas mammals have developed grea...

Vanishing beetle horns have surprise function

... Despite the growing presence of developmental biology in evolutionary studies, "Even today, evolutionary theory is very much a theory of adults," Moczek said. "But evolution doesn't morph one adult shape into another. Instead there's an entire lifetime of development that we can't afford to ignore." ...

Comprehensive model is first to map protein folding at atomic level

.... Shakhnovich, professor of chemistry and chemical biology in Harvard's Faculty of Arts and Sciences. "One of the great problems in science has been deciphering how amino acid sequence -- a protein's primary structure -- also determines its three-dimensional structure, and through that its biological functio...

Ongoing collapse of coral reef shark populations

...tioning of coral reef ecosystems. The reproductive biology of reef sharks makes them particularly vulnerable to fishing, but until now, there have been no studies of the response of these sharks to fishing pressure. The new work focused on Australia’s Great Barrier Reef, which is widely considered to be ...

Sequencing of the oyster mushroom genome

Moreover, an understanding of the evolutionary history registered in the genome of the oyster mushroom and its comparison with other histories registered in other genomes that have been ?or are current...

A valuable fly for research into disease

...aluable insight into the fundamental principles of biology and genetics. Only in recent years, however, and thanks in large part to the discovery of the high degree of homology between the genetic make-up of flies and vertebrates, has Drosophila emerged as one of the most effective model systems to analyze t...
