Immune cell communication key to hunting viruses, Jefferson immunologists show

...ing a signal among only a few T-cell receptors and boosting the T-cell response. This helps explain how only a few virus-infected cells can cause a killer T-cell response. They report their findings this week in an online edition of the Proceedings of the National Academy of Sciences. Understanding how the...

Buildup of damaged DNA in cells drives aging

...ed hormonal changes that halted growth, while also boosting maintenance and repair. Because growth hormone levels go down as we get older, contributing to loss of muscle mass and bone density, the investigators systematically compared the gene expression pattern of their progeroid mice to normal old mice t...

MIT designs portable 'lab on a chip'

...des a greater degree of flow control. The key to boosting energy efficiency is altering the electric field in the channel, Bazant said. Instead of placing electrodes at each end of the channel, as in capillary electro-osmosis, the voltage can be lowered substantially with alternating current (AC) applied at...

Public Library of Science to launch new, open access journal on neglected tropical diseases

...cted Tropical Diseases will play a crucial role in boosting the efforts of neglected tropical disease researchers, health professionals, teachers, and advocacy groups in developing countries." "There are thousands of scientific and medical journals, but very few have focused on these diseases," said Regina ...

Queen bee promiscuity boosts hive health

... promiscuity improves colony disease resistance by boosting the genetic diversity of their offspring, the worker bees. "This required a particularly nasty experiment, in which we inoculated colonies with the most virulent disease of honeybees that is known, the dreaded American foulbrood disease," said Seeley...

Malaria may fuel spread of HIV in sub-Saharan Africa

...e two diseases, while HIV may be playing a role in boosting adult malaria-infection rates in some parts of the region, according to a new study by researchers at Fred Hutchinson Cancer Research Center and the University of Washington. The findings, published in the Dec. 8 issue of Science, found that because...

With fruit fly sex, researchers find mind-body connection

... both sexes, repressing male courting behavior and boosting female receptivity. Fruitless and doublesex act together, as a switch system, to affect this sexual behavior. "The big story is the crossover between the 'mind' and 'body' pathways," McKeown said. "If sexual behaviors are genetically controlled in...

Health Canada approves cold and flu medicine

Comprehensive therapeutic claims require support by the highest level of scientific evidence: randomized, double-blind, placebo-controlled clinical trials. “This is our strongest point of medical recognition to date, and coming...

Corals that can fight global warming may one day help fragile reefs

...trend." Yet there seems to be future promise for boosting the immunity of coral reefs, Harvell reported. Collaborators Rotem Effrony and Eugene Rosenberg in Tel Aviv, Israel, have isolated viruses that can consume several bacteria that are deadly to the more sensitive corals....

Switching genes to overdrive improves muscular dystrophy symptoms in mice

Genomic Analysis Uncovers New Targets for HIV Vaccine

...d the search for an HIV vaccine that would work by boosting the protective effects of one or more of these genes, and help the body's own immune system overcome an infection. One of the genes looks particularly attractive as a vaccine target. The study, published early online by the journal Science July 19, ...
