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

...ciety face greater risks than others, the safe sun message is one that we all need to heed if we are to halt rising skin cancer rates” concludes Dr Hoey....

Palau's coral reefs show differential habitat recovery following the 1998 bleaching event

...missions that affect climate change. The take-home message is that we can accelerate the recovery rate of coral reefs by adapting human behavior and reducing local pressure on reefs; this research provides encouragement and incentive for local management. "Clearly, action is required at both...

Power-boosting signal in muscle declines with age

...nd type 2 diabetes that occurs with aging. "The message of this paper is that, with aging, the AMPK pathway has reduced activity," Shulman said. "So, one probably has to work harder to maintain the same level of fat oxidation and mitochondrial biogenesis in muscle." The number of mitochondria within mu...

Bisexual fruit flies show new role for neurochemical

... think about -- the neurotransmitter that moves in message packets across the synapse. Instead, it is what Featherstone calls ambient extracellular glutamate, which just floats around the nervous system and has generally been ignored because no one knew where it came from or what it was doing. For years, s...

Destructive enzyme shows a benevolent side

...esearchers were unable to detect any sign that the message was destroyed. "The fact that we don't see an acceleration of mRNA decay suggests that something in the stress response protects these mRNAs from being degraded, even though the degrading enzyme PMR1 is there in the stress granules with its target...

Scientists find potential 'off-switch' for HIV virus

...l. The p300 enzyme converts the Tat protein into a message that activates the virus and creates more Tat protein, and eventually converts the T cell into an active HIV factory. "The more of these [messages] sensed within the cell, the more Tat proteins the gene creates, resulting in a snowball effect tha...

New research shows that flu is a trigger of heart attacks

...for preventing heart attacks. "My public health message is that flu is an important killer in cardiac patients. If people can recognise that the flu vaccine has specific cardioprotective effects, then high-risk people will be more likely to make sure that they receive the influenza vaccine every year. We ...

RNAi shows promise in gene therapy, Stanford researcher says

...r strand of RNA that is relaying a protein-coding message from a gene. With that protein-coding message removed, the gene's message is effectively destroyed. When used as gene therapy, RNAi turns off ge...

A steady, high-fat diet is bad, but the news gets worse

...hesis. Campbell cautions that despite the grim message that even one high-fat meal is unhealthy, more research is needed to fully understand how the mechanisms work. "Telling people to never eat something is probably not a good way to promote a better diet," he says. "At the same time we do have an epide...

Microfluidic chip helps solve cellular mating puzzle

Lizards 'shout' against a noisy background

...ade. "They have to have a strategy to get their message across," Ord said. Ord videotaped two species of anole lizards, Anolis cristatellus and Anolis gundlachi, in the Caribbean National Forest in Puerto Rico. He found that the more "visual noise" in the background, the faster and more exaggerated the...

Ape gestures offer clues to the evolution of human communication

...ngle gesture may communicate an entirely different message depending upon the social context in which it is used. "A chimpanzee may stretch out an open hand to another as a signal for support, whereas the same gesture toward a possessor of food signals a desire to share," said Pollick. "A scream, however...

HIV dementia alarmingly high in Africa

...each of HIV dementia, but this study sends a clear message that it exists in high proportions in sub-Saharan Africa and is an under-recognized condition that needs to be studied and treated," Sacktor says. Of the estimated 40 million adults and children worldwide who are living with HIV infection, an esti...

ASU researchers test antibacterial effects of healing clays

... of physicians, says that it was really the second message that finally drew her to the project. "He said, 'I guess that no American scientists are interested in helping poor people in Africa.'" He guessed wrong. Armed with 100 grams of green powder (clay high in reduced iron), Williams not only took the ...

To slow AIDS in Russia, treat HIV-positive addicts, Stanford study says

...cts will receive treatment, Owens said. "Our main message is that really to have an impact on the epidemic, you have to treat both the drug users and non-drug users." ...

Train your brain to hear your friends at a party

...the increase in light levels and the brain sends a message to the eye to tell it to contract the pupil and let in less light. This is a feedback system where the brain is getting information from the eye about its surroundings, processing that information, and sending messages back to the eye to help it cope...

Need to pull an all-nighter?

... One surprise in the research was that the main message telling the brain to go to sleep probably does not come from neurons, but from neighboring glial cells, which appear to produce the greatest amounts of nitric oxide. Until recently, glial cells have been assumed to play only a supportive role in the ...

Hopkins researchers discover how brain protein might control memory

... where one person taps her neighbor and whispers a message that is passed on in similar fashion to the next person in line, nerve cells connect and "talk" to each other by relaying messages - usually by passing small chemicals - from cell to cell. When nerve cells connect with each other in the brain, on...

Mayo discovers protein as potential tactic to prevent tumors

...s first author Haojie Huang, Ph.D. "If the genetic message cannot be repaired, our studies show that CDK2 can...cell dies without propagating its damaging genetic message to progeny cells of its own." "As patients and their physicians seek to control or cure tumors, r...

Brains can recover from alcoholic damage but patients should stop drinking as soon as possible

... University of Wuerzburg, Germany, said: "The core message from this study is that, for alcoholics, abstinence pays off and enables the brain to regain some substance and to perform better. However, our research also provides evidence that the longer you drink excessively, the more you risk losing this capac...
