Genomic Analysis Uncovers New Targets for HIV Vaccine

...cience, and the results of this analysis represent just the first of what should be many advances. The technology used and collaborative efforts involved were truly remarkable: together as a group we were able to do something that none of us individually could accomplish. The results of this and future CH...

Scratch no more: Gene for itch sensation discovered

...imited. Historically, scientists regarded itch as just a less intense version of the pain sensation. As a result, research on itching has been somewhat neglected. "Many genes have been identified in the pain pathway," says Chen, associate professor of anesthesiology, psychiatry and molecular biology and ...

Researchers discover inherited mutation for leukemia

...tics program. "It does not shut down the gene, but just lowers its expression somewhat. "Recently, many cancer geneticists have come to believe that such subtle changes are common causes of cancer, and this is one of the first, strong examples of that principle." The study succeeded because it com...

Math that powers spam filters used to understand how brain learns to move our muscles

... Thursday and believe strongly that Friday will be just as bad,” says Shadmehr. E-mail spam filters operate on a similar principle; they predict which key words are “probably” attached to mail you don’t want and “learning” as they go to fine tune what they exclude from your in-box. The computer model,...

Modeling the restless brain

In this "resting state," waves of neural activity ripple through the brain, creating fluctuating and ever-changing patterns. Sporns and Honey...

How sneaky HIV escapes cells

... which are generally broken and useless. However, just as retroviruses exploit other cell processes for their own ends, it now appears they rely on exosomes to get out of infected cells and infect fresh cells. As such, drugs that interfere with exosome formation might be one way to inhibit HIV infections...

CSIRO scientists join fight to save 'Tassie devil'

... devil to survive the DFTD threat was crucial, not just because it is a major tourism attraction but also to ensure devils continue to play the vital role they have in maintaining Tasmania’s environmental balance. Other collaborators include: the Department of Primary Industries and Water (DPIW) and t...

A new plant-bacterial symbiotic mechanism promising for crop applications

...dyrhizobium, bacteria of the Rhizobia family, have just revealed a new mode of communication at molecular level between these two organisms. The bacteria of this original model have their own photosynthetic pathway, a unique property in the rhizobia (2). This special character confers on it the exceptiona...

Hormone helps mice 'hibernate,' survive starvation

...eared as if they were starved, even after they had just eaten,” said Dr. Kliewer. Because limiting food consumption is known to have a range of beneficial effects, such as lowering blood pressure, cholesterol and glucose levels in the blood, Dr. Kliewer is interested in understanding how FGF21 impacts ...

Longer treatment benefits sleep apnea patients

...worn while the patient sleeps and works by blowing just enough air into the nose to keep the patient's throat open. Because they often find the CPAP device cumbersome, many patients do not use it consistently or for long enough periods while sleeping. In the current study, for example, patients used ...

Sun exposure early in life linked to specific skin cancer gene mutation

...ancers often contain different gene mutations, but just how these mutations contribute to the cause of melanomas has been a mystery. A new clue comes from scientists at the University of North Carolina at Chapel Hill Schools of Medicine and Public Health. Their research indicates that early life sun expo...

Rising skin cancer rates are more likely to affect wealthy people, says 12-year review

Researchers who looked at official cancer statistics for nearly 23,000 patients over a 12-year period, reported a 20 per cent increase in patients and a 62 per cent increase in skin canc...

'Lucky 13' as new gene discovery offers further hope for childhood blindness

...function has been lost completely, but carriers of just one copy of the mutation, who will almost certainly have reduced protein levels, nevertheless function perfectly normally," explains Professor Inglehearn. "This being the case, restoration of even a tenth of the missing protein may be enough to resto...

U-M researchers discover gene switched off in cancer can be turned on

...nd no mutations to the gene but rather that it was just silent – essentially like a switch that had been turned off. Knowing that a class of drugs called histone deacetylase inhibitors, or HDAC inhibitors, can affect gene expression, the researchers applied these drugs to the cells and found the BRM expre...

A survey of Southern Sudan was part of the initial planning for the trip, but Fay was unable to complete his surveys due to...
