Common cancer gene sends death order to tiny killer

... themselves can act to either promote cancer or to stop cancer spread." To test their idea, the team first chemically damaged the DNA of two sets of colon cancer cells, one missing p53 and the other containing healthy p53. They then looked for any of the 500 known human microRNAs that are activated onl...

Old memory traces in brain may trigger chronic pain

...ion, Apkarian said. “To control it, they tried to stop the sensory input to the brain. ”We are saying there’s a cognitive memory and emotional component in the brain that seems abnormal. Easing that may have a bigger effect on suffering.” Chronic pain is not caused by a single mechanism, Apkarian not...

CSIRO scientists join fight to save 'Tassie devil'

...future research and management. “The aim is to stop the disease in it tracks and we want to bring our experience of controlling infectious diseases to the research community involved to help achieve this,” Dr Hyatt said. A chemist and Spectroscopist at CSIRO Textiles and Fibre Technology, Dr Jeff...

Study shows big power of small RNAs, not just proteins, in halting cancer

...iously damaged p53 pathway caused cancer tumors to stop growing and even eliminate themselves by activatin...known as miR-34. The fact that p53 uses miRNAs to stop tumor cell growth reveals a completely new dimension of this critical cancer fighting pathway and i...

Undergraduate research shows leaderless honeybee organizing

... fly. The researchers document that the workers stop using the vibration signal when the queen flies and leaves the nest with the swarm. Piping, however, continues in the swarm, as the bees need to make the queen fly again once a new nest site has been selected. “Drew Pierce did this project last...

Male circumcision overstated as prevention tool against AIDS

...n rights and we must do everything in our power to stop it. To argue we should do nothing about infected prostitutes during an AIDS epidemic because of a fear of creating a stigma against the infected would be like an animal rights activist claiming that a rabid dog must be allowed to run free in a neighb...

Ancient retrovirus sheds light on modern pandemic

...er at fighting HIV actually inhibit its ability to stop PtERV1 and vice versa, which indicates that this antiviral gene may only be good at fighting off one virus at a time. Uncovering the story of TRIM5a's role in battling one ancient retrovirus while increasing human susceptibility to modern-day HIV "...

HIVMA opposes The Gambia's unproven AIDS remedy

... Gambia is encouraging citizens living with HIV to stop taking antiretroviral medications in order to try ...ple false hope, while at the same time making them stop treatment that has been demonstrated to save lives." "Any treatment that claims to alleviate this...

Mice with a migraine show signs of brain damage

...that the focus should be on prevention, which will stop not only the pain but also minimize potential damage,?said Maiken Nedergaard, M.D., Ph.D., the neuroscientist who led the research team. She is a professor in the Department of Neurosurgery and a member of the Center for Aging and Developmental Biolo...

Sleepless for science: Flies show link between sleep, immune system in Stanford study

...ptible to infection. "When flies get sick, they stop sleeping," said David Schneider, PhD, assistant professor of microbiology and immunology. "Disrupting sleep in turn disrupts the immune system, which makes them even more infected and it's downhill from there in a 'spiral of death.'" Schneider is the...

First demonstration of new hair follicle generation in an animal model

...king wnt proteins, they also found that they could stop the production of hair follicles in healed skin. Increased wnt signaling doubled the number of new hair follicles. This suggests that the embryonic window created by the wound-healing process can be used to manipulate hair-follicle regeneration, l...

Genome of yellow fever/dengue fever mosquito sequenced

...would make the mosquito resistant to the virus and stop its role as a vector for disease. Although that scenario is challenging, the payoff is potentially great, Tu said. "By introducing TEs in a more or less random way to see what happens to the laboratory mosquitoes, the TEs become a tool to study t...

Hives ferment a yeasty brew, attract beetle pest

...e hive can be saved," says Tumlinson. "If they can stop the beetles and remove eggs in the hive, the hive recovers." Honeybees are of major economic importance in agriculture as the major pollinating force for much orchard fruit and vegetables. Many of these fruits and vegetables will not produce without...

Leeches ferry infection among newts

...says Raffel . "When newts get infected, they often stop breeding, apparently to shore up their immune system to fight off the disease. But that comes at the cost of having fewer offspring," he adds. Findings from the study may also indicate that human activities could lead to increases in the infection...

Rapid response was crucial to containing the 1918 flu pandemic

Kansas City banned weddings and funerals if more than 20 people were to be in attendance. New York mandated staggered shi...

Sandia researchers take new approach to studying how cells respond to pathogens

...ly steps could lead to better ways to diagnose and stop disease before there are symptoms and development of more effective therapeutics. Most existing research into how immune cells respond has been done by looking at large cell populations. The Sandia researchers say information gathered from a large...

Researchers design pulsed mircrojet system to deliver protein drugs without pain or bruising
