AIDS drug from sunflowers

...tually put a stop to the fungus. The agricultural engineer Claudio Cerboncini wanted to find out what chemical weapons the fungus-resistant sunflowers have at their disposal. In his PhD thesis for Professor Heide Schnabl of the Bonn Centre of Molecular Biotechnology (CEMBIO) Claudio infected different types...

Honeybee decision-making ability rivals any department committee

...cher (Cornell Ph.D. '85) and Ohio State University engineer Kevin Passino have been observing, videotaping, devising experiments and mathematically modeling honeybee swarms. "The bees' method, which is a product of disagreement and contest rather than consensus or compromise, consistently yields excellent ...

Researchers develop portable 'vein finder' for faster, more accurate injections

UCSB researchers discover shape matters to macrophages

... says the next challenge is clear: learning how to engineer the shape of particles to enhance, delay or prevent phagocytosis. Such a discovery, for example could allow researchers to design drug carriers that can be purposefully retained by the body for a longer period of time, or could help researchers creat...

UW-Madison engineers squeeze secrets from proteins

...ay," says Juan de Pablo, a chemical and biological engineer at the University of Wisconsin-Madison. "What we d...tand those high temperatures. So what people do is engineer enzymes that do not unfold when you put them in hot water. They design enzymes that are more stable ...

UW scientists unravel critical genetic puzzle for flu virus replication

..., by manipulating key genetic elements, to quickly engineer viruses that can be used to mass produce vaccines. Researchers have been trying to make viral vectors using nine genetic segments, a strategy that has never worked, Kawaoka notes. "To develop an influenza virus vector, we have to stick to this eight...

Intelligently designed molecular evolution

"This technology could be used by pharmaceutical manufacturers in the future to create specific enzyme products." Keasling is director of Berkeley Lab's Physical Biosciences Division, and a professor of chemical en...

Source of crucial immune cell in the skin discovered

... replaced "should contribute to ongoing efforts to engineer immune responses in vaccine design and tumor immunotherapy and to a better understanding of the immune response against skin pathogens." "Now that we know which cells are the precursors to Langerhans cells and the importance of Csf-1, we may be able...

Scientists develop protein-sequence analysis tool

... differ, such information can also help scientists engineer proteins to do new jobs. Now scientists at the U.S. Department of Energy's Brookhaven National Laboratory have written a computer program "to sort the informational 'wheat' from the 'chaff,'" said Brookhaven biochemist John Shanklin, who leads the r...

Scientists map one of biology's critical light-sensing structures

...ding to Vierstra and Forest, it may be possible to engineer and introduce into crops phytochromes that respond to different wavelengths of light, or are more or less active. These changes, in turn, could allow plants to grow under different climate regimes or flower at different times of the year, for example...

Genetic defenders protect crops from fungal disease
