Hepatitis A infections, usually transmitted via contaminated food, can cause debilitating illness, but protection afforded by the hepatitis A vaccine last more than a decade, a new study shows.

NYU Langone Medical Center scientists and their collaborators at the Scripps Research Institute in La Jolla, California, have discovered an unexpected cause for the fatal seizures seen in mice with viral meningitis, an infection of the central nervous system, according to a study published in the journal Nature. The finding may lead to a new way of thinking about how the human immune system responds to viral diseases.
The NYU researchers, Michael L. Dustin, Ph.D., the Irene Diamond Professor of Immunology and Professor of Pathology at NYU School of Medicine, and Jiyun V. Kim, Ph.D

Circumstantial evidence hints that the cytomegalovirus, a common herpes virus, may play a role in aggressive brain cancer, but big questions remain.
Fat cells also linked to prion infection

Researchers have confirmed that adipose cells can carry prions, or at least that healthy test animals injected with infected fat cells become sick.
Prions are small, non-living chunks of misfolded proteins that can cause diseases such as scrapie and mad cow disease.
Engineered bacteria create high-energy biofuel

Researchers have designed an entire molecular assembly line in bacterial cells that pieces together a kind of alcohol that isn’t normally made by known living organisms. This alcohol could serve as a biofuel that, unlike ethanol, has a high energy density and could be used in gasoline and jet fuel
An Artist Develops a New Image--With Aid of Bacteria
sea-maid submitted, created time 1 week 1 day (www.sciencemag.org)
Nearly five years ago, molecular biologist Edward Marcotte recalls, a high school dropout walked into his office at the University of Texas (UT), Austin, to talk shop. Despite the visitor's unconventional background, which included a stint as a video game programmer, Marcotte says that Zack Booth Simpson "won me over instantaneously. He was so clearly intelligent." They ended up talking for hours on topics such as Marcotte's use of data mining to extract information about the protein networks that control cellular functions.

Peering at structures only atoms across, researchers have identified the clockwork that drives a powerful viral nanomotor.
Because of the motor's strength--to scale, twice that of an automobile--the new findings could inspire engineers designing sophisticated nanomachines. In addition, because a number of virus types may possess a similar motor, including the virus that causes herpes, the results may also assist pharmaceutical companies developing methods to sabotage viral machinery.

Drilling Holes Through Deadly Bacteria's Kevlar-like Hide
piggy submitted, created time 1 week 4 days (www.sciencedaily.com)
To protect themselves from human defenses, disease-causing bacteria have evolved a cell wall made from a nearly impenetrable tangle of tightly woven strands. That’s made it difficult for scientists to see what goes on inside these potentially deadly organisms. But that era is now over. Rockefeller University researchers have now figured out how to drill holes through the Kevlar-like hide of gram-positive bacteria without obliterating them, and in doing so, they’ve made it possible to study, from the inside out, most of the known bacteria on the planet.

New technique is quantum leap forward in understanding proteins
piggy submitted, created time 2 weeks 1 day (www.eurekalert.org)
In this ongoing quest, a group of Scripps Research Institute scientists, along with colleagues from the University of California, San Diego, (UCSD) have borrowed from physics to deliver one of those research rarities—an unmitigated success. The group has devised a computational method that, with remarkable accuracy, predicts how bacterial proteins fold and interact
Synthetic Molecules Prevent HIV Virus From Reproducing within the Body, Study Suggests
sea-maid submitted, created time 3 weeks 1 day (www.sciencedaily.com)
Evolving HIV viral strains and the adverse side effects associated with long-term exposure to current treatments propel scientists to continue exploring alternative HIV treatments. In a new study, a University of Missouri researcher has identified broad-spectrum aptamers. Aptamers are synthetic molecules that prevent the HIV virus from reproducing. In lab tests, aptamers known as RT5, RT6, RT47 and some variants of those were recently identified to be broad-spectrum, which would allow them to treat many subtypes of HIV-1.
New Way Men Can Transmit HIV to Women
piggy submitted, created time 3 weeks 1 day (www.sciencedaily.com)
Researchers at Northwestern University have discovered a critical new way a man can transmit the HIV virus to a woman.
Scientists had long believed that the normal lining of the female vaginal tract was an effective barrier to invasion of the HIV virus during sexual intercourse. They thought the large HIV virus couldn't penetrate the tissue.
But new research from Northwestern University's Feinberg School of Medicine has shown for the first time that the HIV virus does indeed penetrate a woman's normal, healthy genital tissue to a depth were it can gain access to its immune cell targets.
"Zinc Zipper" Plays Key Role in Hospital-acquired Infections
piggy submitted, created time 1 month 3 days (www.sciencedaily.com)
Hospital-acquired infections that are resistant to traditional antibiotic treatment have become increasingly common in recent years, confounding health care professionals and killing thousands of patients in the U.S. alone.
Now, in studies that could lead to new ways to prevent this growing public health danger, a team of University of Cincinnati (UC) researchers is exploring a “zinc zipper” that holds bacterial cells together and plays a key role in such infections.
Hospital-acquired infections affect about 1
New Strategy for Broad-Spectrum Anti-viral Drugs Developed

Bavituximab, an anti-viral drug developed by UT Southwestern Medical Center researchers, shows promise as a new strategy to fight viral diseases, including potential bioterrorism agents.
In a study appearing in the December issue of Nature Medicine, groups of guinea pigs infected with a virus similar to Lassa fever virus recovered from the fatal disease when treated with bavituximab alone or in combination with a common anti-viral medication. Bavituximab treatment also cured mice infected with cytomegalovirus, an opportunistic infection that afflicts transplant and AIDS patients.

Discovery of Lentivirus in Lemur Could Shed Light on History of AIDS and HIV
piggy submitted, created time 1 month 6 days (www.sciencedaily.com)
The genome of a squirrel-sized, saucer-eyed lemur from Madagascar may help scientists understand how HIV-like viruses coevolved with primates, according to new research from the Stanford University School of Medicine. The discovery, to be published online on Dec. 1 in the Proceedings of the National Academy of Sciences, could provide insight into why non-human primates don't get AIDS and lead to treatments for humans.
Scientists have long believed that lentiviruses — the family of viruses that includes HIV — started infecting primates within the past million years
Sex Life of Killer Fungus Finally Revealed
piggy submitted, created time 1 month 1 week (www.sciencedaily.com)
Biologists at The University of Nottingham and University College Dublin have announced a major breakthrough in our understanding of the sex life of a microscopic fungus which is a major cause of death in immune deficient patients and also a cause of severe asthma.
The discovery of a sexual cycle in the fungal pathogen Aspergillus fumigatus is highly significant in understanding the biology and evolution of the species and will shed new light on its ability to adapt to new environments and its resistance to antifungal drugs
