Bursts of waves drive immune system 'soldiers' toward invaders

...'re getting our first glimpses that take us beyond knowing that this protein is important for cell motility to learning how it might organize the complex choreography of cell movement." The videotape of the unsuspected action shows wave upon wave advancing like a series of exploding fireworks. The novel b...

Satellite tracking will help answer questions about penguin travels

...ife of the project. The researchers have no way of knowing whether the birds will go to southern Argentina or the Malvinas, or whether they will follow a straight course to the breeding grounds or take a circuitous route. "After we release them, they could just hang out at Mar del Plata for a m...

Scientists discover new way to study nanostructures

...eak in such measurements signifies a resonance and knowing that we have intrinsic high-frequency Josephson current oscillations, we started looking into the possible physical mechanisms, said Marchenkov, assistant professor in the School of Physics. The team hypothesized that the new measured peaks likely ...

Protein pulling -- Learning how proteins fold by pulling them apart

...o acid representing a bead on the strand. However, knowing the order of the amino acids in the strand gives no clue about how a protein functions. That's because every protein folds into a three-dimensional shape within about one second of being made, and it is this shape that dictates the protein's function...

Insects to solve crimes

...iven that, if the larvae are found in the body and knowing their species and corresponding growth table, a calculation of how long the person has been dead can be made. The research team is undertaking a reference collection of insects of forensic interest, including all their larval stages, and which will b...

Translating form into function

...yme, a search that has never succeeded simply from knowing an enzymes configuration. The key to the teams success was a computational feat: simulating candidate substrates that mimicked unstable intermediate molecules those that exist only briefly as the catalyst turns the substrate into a new molecule. B...

Early fire risk for mountains near Los Angeles

...and equipment. Homeowners may find this useful for knowing when fire danger will be high so they can be better prepared to evacuate, clear brush from around their homes and watch for arsonists. Study co-author Max Moritz, a wildland fire specialist at the University of California, Berkeley, adds: Although...

Autism-related proteins control nerve excitability, researchers find

...We can never design a therapeutic strategy without knowing what these mutations do. The proteins are called neuroligin-1 and neuroligin-2. At the junction of two nerve cells, called a synapse, the proteins stick out from the surface of the cell that receives a signal from the first cell. The neuroligins b...

Largest synthetic gene ever built offers insights into anti-malarial drug resistance

...xactly how they are doing it," Roepe says. "Still, knowing the pH values can help pharmacologists and chemists redesign a molecule to take advantage of these changes."...

ACS News Service Weekly PressPac -- May 23, 2007

...ca. Miners add mercury as they sift soil and rock, knowing that mercury will capture bits of the precious metal to form an alloy from which the gold then can be separated and sold . During the retrieval process, , the alloy is heated and toxic mercury is driven into the air. C&EN describes upcoming decisi...

Analysis reveals extent of DNA repair army

...t figured out," Elledge said. He noted that simply knowing that BRCA1 comes in three distinct flavors gives researchers the chance to sort out the role of each in the DNA damage response and the onset of tumors. An intriguing offshoot of the findings, Elledge said, is that they provide a potential lead into ...

Salmon tracking program expands to California

... our genetic profile on the tissue samples without knowing what the coded wire tags said and correctly identified the hatchery of origin for all 31 fish. That's pretty good confirmation that the testing works." The Oregon Watershed Enhancement Board has provided another grant, totaling $590,000, for the 20...

Reproductive speed protects large animals from being hunted to extinction

.... "You can completely change the ecosystem without knowing it if you hunt these animals to extinction," she said. Price isn't optimistic that much could be done to incorporate her findings into new game policies, but this new understanding of the importance of reproductive rates could help conservation man...

UF scientists identify cancer virus' genetic targets

...ecular genetics and the papers lead author. But by knowing at least some of the major genes being targeted, scientists have a place to start as they strive to develop therapies. "The Kaposis sarcoma herpesvirus is a very efficient parasite," said Jae U. Jung, Ph.D., a professor of microbiology and molecula...

Einstein's Dr. Vern Schramm elected to the National Academy of Sciences

...t can also influence cells to become cancerous. By knowing the transition-state structure of enzyme-catalyzed reactions, we can design powerful inhibitors that can block those enzymes from acting and thereby treat or prevent cancer and other diseases. One such inhibitor that Dr. Schramm has designed, known...

Study finds fecal microbes high in New Orleans sediments following Hurricanes Katrina and Rita

...nt. Amaral Zettler points out the importance of knowing the microbial landscape of an area before a natural disaster hits. Some pathogens are endemic to the natural environment and some are introduced through sewage and run-off. Likewise, microbial communities are under the influence of seasonal variabil...

Salk researchers discover first gene that specifically links calorie restriction to longevity

...iction (CR) to longevity. After 72 years of not knowing how calorie restriction works, we finally have genetic evidence to unravel the underlying molecular program required for increased longevity in response to calorie restriction, says Andrew Dillin, Ph.D., an associate professor in the Molecular and Ce...

New treatments have major impact on heart failure rates

Our study enables us to look at differences in practice in a clinical setting over time and it has reflected significant changes in how patients with hear...

University of Alberta researchers unravel intricate animal patterns
