Research holds promise for herpes vaccine

... secure government funding to advance his research toward a human vaccine. "I'd like to take this concept from the chalkboard to the clinics," he said. ...

Ferns provide model for tiny motors powered by evaporation

...ulls on the tips of the ribs so that the tips move toward each other, straightening out the spine of the device. In this way, the closed device opens wide---it moves. They plan to add electrical components to the device in an attempt to generate electricity. They predict that the device will be able to gen...

Worms produce surprise insight into human fever

...ven cold-blooded “poikilotherms?like worms migrate toward warmer environments in response to infections. But the mechanism of fever as a response to infection is still largely unknown. The activation of the HSF-1 pathways by heat shock and its function in C. elegans immunity provides both a molecular ex...

Researchers image molecular motor structural changes

...s they move along microtubules. In the first step toward this breakthrough, the researchers used an existing technology, electron microscopy, which normally enables scientists to magnify very small biological structures up to 400,000 times their original size. Electron microscopes use beams of electrons in...

UCSD researchers discover internal compass of immune cell

... puzzle of how neutrophils find their way and move toward sites of injury or infection in the body," said se...hain of events necessary to direct the neutrophils toward its goal begins when ATP is released from the region of the cell surface closest to the source of ch...

Researchers create genetically matched embryonic stem cells for transplantation

...clear transfer, and therefore may allow us to move toward human applications sooner." In the new study, Daley, first author Kitai Kim, PhD, and colleagues at Harvard Medical School, Brigham and Women's Hospital and Massachusetts General Hospital used unfertilized eggs of mice to create so-called partheno...

MIT designs portable 'lab on a chip'

...e idea," said Bazant. Thorsen's group is working toward integrating the pumps into a portable blood analysis device, which soldiers could carry onto the battlefield. If exposure to chemical or biological weapons were suspected, the device could automatically and rapidly test a miniscule blood sample, rath...

Patients can report statins' adverse effects on new web site

...al and adverse," said Golomb. "Our work is geared toward expanding knowledge of the impact of statins in order to better inform the public and the medical community. By filling out the web site survey, statin patients can help us to help others with the same concerns." ...

Hospital-acquired infections -- Inevitable?

...harm free. Changing our mindset will go a long way toward restoring the faith of the public and improving the overall quality of medical care in the United States." "I sincerely hope that this special supplement to the American Journal of Medical Quality will help us to obtain this worthy goal," Dr. Nash ...

Professors to develop hand-held pathogen testing device

The company is developing implantable biosensors ?integrating...

Mars mission Risk 29: Scientists research ways to reduce radiation-induced brain damage

...ing its gravitational pull to sling the spacecraft toward Mars. That means flying closer to the sun and spending months on the opposite side. "The sun is basically a big nuclear reactor," said Britten. The scientists hope to determine how much shielding the spacecrafts and astronauts will need, and also...

Researchers use multiphoton microscopy to watch chromosomes in action

...fly cells. The advance could be a significant step toward understanding the basic processes that underlie gene expression. The discovery was the result of cross-disciplinary collaboration between Webb and John Lis, Cornell's Barbara McClintock Professor of Molecular Biology and Genetics. Jie Yao, who recen...

St. Jude finds clues to hearing loss from chemotherapy

...esearchers. The investigators took the first step toward these ambitious goals by identifying 17 families of mice whose offspring carry one or more of a variety of mutations that cause them to lose the ability to hear high-frequency sounds, according to Jian Zuo, Ph.D., associate member of the St. Jude Dep...

International team analyzes human genetic variation in key immune region

...vide the tools needed to begin the initial efforts toward identifying genetic risk factors in the MHC for common immune-mediated diseases. Such endeavors, involving researchers at the Montreal Heart Institute, the University of California, San Francisco and the Broad Institute of MIT and Harvard, are now un...

A human taste for rarity spells disaster for endangered species

... the authors hope that education may go a long way toward curbing these human activities. Education could even mitigate the damage of trophy hunting and luxury consumption if society stigmatized activities responsible for driving a species to extinction and people could no longer take pride in displaying su...

MIT creates 3-D scaffold for growing stem cells

...ferentiating into needed body tissues or migrating toward bone marrow and other natural destinations. "What makes these designer scaffolds particularly interesting is that cells survive longer and differentiate better without additional soluble growth factors," Zhang said. "This suggests that extracellul...
