HIV dementia alarmingly high in Africa

... study translates across sub-Saharan Africa, we’re looking at more than 8,000,000 people in this region with HIV dementia," says Sacktor. Sacktor says an extremely high rate of HIV dementia in Africa and other poor regions of the world adds enormously to the social and economic burden of their populations...

Overfishing large sharks impacts entire marine ecosystem, shrinks shellfish supply

...reased considerably, according to research surveys looking at the past 16 to 35 years. Cownose rays are most conspicuous among the 12 species showing increases because of their near-shore migrations. With an average population increase of about eight percent per year, the east coast cownose ray population ma...

Human preference for other species could determine whether they survive

..."I went to great lengths to ensure that what I was looking at was a purposeful set of pictures and not one just based on logistics," he said. The popularity rankings were similar across all four books, he added, which suggests that human preferences could be widely shared. The work has been published in ...

Dig deeper to find Martian life

...ssions. The best chance we have of finding life is looking in either the sea at Elysium or fresh craters." The team found that the best places to look for living cells on Mars would be within the ice at Elysium because the frozen sea is relatively recent ?it is believed to have surfaced in the last five...

Chronic pain up almost 40 percent among US workers in past decade

"This opens up an entirely new way of looking at stress and cancer that's different from current interpretations," explained Ronald Glaser, a professor of molecular virology, immunology and medical genetics, and director of the Institute for Behavioral Medicine Research at Ohio State University ...

Single molecule extends fat mice lives by reversing gene pathways associated with disease in obese

...any.] Investigators identified resveratrol while looking for compounds that activate Sir2, an enzyme linked to lifespan extension in yeast and other lower organisms. For the last 70 years, scientists have been able to increase the lifespan of a variety of species by reducing their normal food consumption ...

ASU researchers test antibacterial effects of healing clays

Global map shows new patterns of extinction risk

...tain a really detailed picture of biodiversity. By looking at the numbers of endangered mammals, birds and amphibians in these squares, we have been able to see how this real picture varies from assumptions that have previously been made about global biodiversity of endangered species." Professor Owens ad...

Dopamine used to prompt nerve tissue to regrow

... "Dopamine was a good starting point, but we are looking into other neurotransmitters as well," Wang said. The team's next step is to verify findings that the material stimulates the reformation of synapses in addition to regrowth. "A successful nerve regeneration will require the nerve to synapse w...

Early-stage immune system control of HIV may depend on inherited factors

..."While we can't say this for sure right now, it is looking like both the HLA Class I molecule and the specific viral sequences being displayed contribute to the strength of immune response against primary HIV infection," says Altfeld. "In addition, the combination of Class I molecules that an individual exp...

Chronic jet-lag conditions hasten death in aged mice

...earchers examined the mortality link in earnest by looking at how young mice and old mice fared when subjected to two different types of light-cycle shifts. In one regimen, mice experienced a six-hour forward shift once a week, while in the other, mice experienced a six-hour backward shift. A "control" group...

Preliminary study finds holographic imaging system promising for cancer treatment planning

...over current 2D radiation planning systems. We are looking forward to an expanded study with a larger number of patients to determine the true potential of this system." The Perspecta Spatial 3D System has not received FDA approval and is not intended for use in clinical diagnosis, nor may it be used to p...

Science researchers genetically transform immune cells into tumor fighters

... Rosenberg and colleagues have a long history of looking for ways to boost the body's natural immune defenses against cancer, focusing specifically on T cells, a special type of immune cell that can recognize and attack "foreign" cells such as those found in tumors. In their earlier experiments, the resear...

Uncovering DNA's 'sweet' secret

...t has a more haphazard appearance than normal DNA, looking more like a "slowly writhing ribbon" than the tightly twisted ladder of DNA. "The reason that DNA was 'picked' is not because it's thermodynamically extremely stable," Egli said. "There are others - including homo-DNA - that are actually superior i...

Underweight women at greater risk of miscarriage

"While looking at the satellite pictures, I noticed that cloud properties over large phytoplankton blooms were significantly different from those that occurred away from the blooms," recalled Meskhidze, now an assistant professor in NC State's College of Physical a...

Common ancestry of bacterium and plants could be key to an effective new treatment for chlamydia

...igning a key to fit a lock by opening the lock and looking inside. The research is being done in collaboration with Charles Gilvarg from Princeton University. "He's the biochemist who characterized the lysine pathway back in the 1950s, and so he had intimate knowledge about the steps of the pathway," said...
