New methods of gene delivery using lasers

Leading laser scientists at the University of St Andrews have developed a new method of delivering genes to cells using laser light. The new technique, which is cheap and powerful, could have important implications for future studies in biomedicine and healthcare. Optical t...

Influenza vaccine uses insect cells to speed development

...tically modified baculovirus and caterpillar cells scientists from Protein Sciences Corporation have been able to speed up a key step in the development of an experimental cell-based influenza vaccine. They report their findings today at the 2005 American Society for Microbiology Biodefense Research Meeting. "...

South America's vast pantanal wetland may become next everglades, UNU experts warn

...est freshwater wetland, of active interest to U.S. scientists for insights into the lost biodiversity of Florida's famed Everglades, altered by drainage projects starting in the 1940s to make way for development and agriculture. In a message to mark World Water Day, March 22, UNU says the Pantanal provides eno...

X-Ray Beams And Fruit Fly 'Flight Simulator' Aid Scientists' View Of Muscle Power

...tating shutter used in the earlier experiment. IMF scientists Carl Silver and Gill Gianetti fabricated the high-speed device. “How the fly’s muscles turn off and on at 200 times a second has been a mystery that we now can solve in detail using these new technologies?Maughan said. Maughan and his colleagues?re...

Scientists discover that host cell lipids facilitate bacterial movement

...in the Journal of Biological Chemistry, a group of scientists provide insight into the molecular mechanisms behind this infection technique. The research appears as the "Paper of the Week" in the March 25 issue of the Journal of Biological Chemistry, an American Society for Biochemistry and Molecular Biology j...

Scientists solve structure of key protein in innate immune response

... published in the Journal of Biological Chemistry, scientists in Korea announced their elucidation of three-dimensional structure of CD14 and showed how it is perfectly suited to bind to certain bacterial products. The research appears as the "Paper of the Week" in the March 25 issue of the Journal of Biologic...

Affymetrix and the Karolinska Institutet Announce Translational Medicine Strategic Alliance

...of complex diseases. About Affymetrix: Affymetrix scientists invented the world's first high-density microarray in 1989 and began selling the first commercial microarray in 1994. Since then, Affymetrix GeneChip(R) technology has become the industry standard in molecular biology research. Affymetrix technology ...

Carnegie Mellon scientists develop tool that uses MRI to visualize gene expression in living animals

In a first, Carnegie Mellon University scientists have "programmed" cells to make their own contrast agents, enabling unprecedented high-resolution, deep-tissue imaging of gene expression. The results, appearing in the April issue of Nature Medicine, hold considerable promise for conducting preclini...

In the migratory marathon, parasitized monarchs drop out early

...nt than non-migratory ones to parasite infections; scientists just uncovered why it is so. Explanation : infected monarchs quite don't make it while migrating long distances, so they can't propagate the infection once arrived at destination. A little-studied outcome of animal migration is whether these long j...

Gene therapy for Parkinson's disease moves forward in animals

An international team of scientists has used gene therapy in two separate studies to r...es. By inserting corrective genes into the brain, scientists studying small monkeys called marmosets prevented brain damage by producing therapeutic levels of a ...

Scientists find fossil proof of Egypt's ancient climate

Earth and planetary scientists at Washington University in St. Louis are studying snail fossils to understand the climate of northern Africa 130,000 years ago. While that might sound a bit like relying on wooly bear caterpillars to predict the severity of winter, the snails actua...

Special Imaging Study Shows Failing Hearts Are 'Energy Starved'

International HapMap consortium expands mapping effort

... The first phase of the HapMap Project has allowed scientists to make important analyses of the human genome that were not possible with just the human DNA sequence, and the International HapMap Consortium plans to publish its comprehensive analysis of this data later this year. The second phase of the project ...

Rats infected as newborns grew up vulnerable to memory problems during an immune challenge

...isrupt memory in immune-challenged adults may help scientists to understand how exposure to germs or environmental stressors before or just after birth may foster susceptibility to neuropsychiatric and neurodegenerative diseases. For example, prenatal viral infection has been implicated in schizophrenia, autism...

Effective Cancer Treatments Follow The Clock

... In experiments, which were conducted in mice, the scientists found that the body's internal biological clock affects the survival of immune cells that are targets of the anti-cancer drug cyclophosphamide (CY). “We became interested in examining this issue because there is a long history of knowledge that chem...

LUCA technologies confirms real-time methane generation

... with microbial consortia from active sites. Luca scientists have also begun to isolate and identify particular members of the Monument Butte microbial consortium. Through partial DNA sequence analysis, the company has identified Clostridia and Thermatoga as two of the key members of this consortium. Clostridi...

Multiple Campylobacter Genomes Sequenced

...ons caused by them. By comparing genome sequences, scientists can learn much more about what makes a bacteria tick than they can learn from a single sequence. Derrick Fouts and his colleagues have taken this comparative approach with Campylobacter. Infection with a Campylobacter species is one of the most comm...
