Federal grant funds research on novel HIV therapy

...award this fall. The grant builds on more than a decade of investigation by Dr. Douglas into substance P, a neurotransmitter long known to be active in the brain and nervous system. Dr. Douglas and colleagues discovered in 1997 that immune cells produce substance P and its receptor, neurokinin-1, and late...

Molecular research suggest shift needed in how some drugs are created

...osophila melanogaster that was determined nearly a decade ago. The death domain is so-named because of a resemblance to proteins that are involved in programmed cell death. "It has been thought in the field that a death domain is a death domain, and molecular recognition takes place in the same fashion," s...

Genetic testing still smart choice, despite uncertainties

...on genetic diagnosis has been used for more than a decade to screen embryos for hereditary diseases such as Down syndrome and other abnormalities. To do this, one cell from an eight-cell embryo is extracted and examined for chromosomal defects. However, as many as half these embryos spawn cells with diffe...

Envisat radar surveillance protects endangered prehistoric fish

...ividual toothfish can live for 40 years but take a decade to reach adulthood: their slow-maturing character makes them especially vulnerable to overfishing. As toothfish numbers have crashed in heavily fished waters off Chile and Argentina, fishermen are increasingly drawn to Southern Ocean fisheries. H...

Max Planck researchers make a breakthrough in plant stem cell research

...ed at the University of Tübingen, Germany about a decade ago. Here it was shown that a gene called WUSCHEL has a key influence on how many cells in the apical meristem actually stay stem cells. However, until now, it was unclear how hormones and regulatory genes, such as WUSCHEL work together to maintain t...

Seaweed yields new compounds with pharmaceutical potential

...arket, Kubanek said. It typically takes at least a decade from the discovery of a compound to the marketing of a new drug. If that does happen in this case, Fijian villagers and the Fijian government would benefit financially from the discovery because of an agreement that is already in place, she added. Be...

Russian 'surrogate' alcohols are a killer

...lcohol, or toxic contaminants. "During the past decade we have been investigating reasons for the very high death rate among Russians," said Martin McKee, professor of European public health at the London School of Hygiene and Tropical Medicine. "We have been looking in detail at men in Izhevsk, a city ...

U. of Colorado researcher identifies tracks of swimming dinosaur in Wyoming

...deo shot during submersible dives made more than a decade ago, the researchers came across footage that offered an explanation for why sea lilies might get up and go. The videos showed sea urchins lurking in gardens of sea lilies, some of which appeared to be crawling away from the predators. In some photos...

Breath of the dragon: ERS-2 and Envisat reveal impact of economic growth on China's air quality

...hina's spectacular economic growth during the last decade has brought many benefits - and some challenges. G...l changes in nitrogen dioxide observed in the last decade from space and highlighted the dramatic changes over China. Nitrogen dioxide (NO2) is associated w...

Creeping crinoids! Sea lilies crawl to escape predators, new video shows

UF study first to quantify validity of DNA I.D. tool using marine snails

A trendy holiday gift within a decade may be a hand-held device that instantly identifies any species from a snippet of animal tissue, says a University of Florida researcher. That may be possible thanks to scientific advances that include the first test quantifying the effectiveness of...

Researchers find Amchitka seafood safe for now

...ciplinary multi-university organization that for a decade has independently studied and reviewed risk issues associated with the cleanup and long-term stewardship of legacy wastes at US Department of Energy sites. Its principal investigator Powers, is Professor of Environmental and Occupational Medicine at ...

Emerald Spectre haunts Ontario's ash forests

...ipping materials, and was present for as much as a decade prior to being identified. The challenge in the Great Lakes region, he says, is the current extent of the infestation. The infected zone now covers all of Ontario's Essex County and extends to include the entire lower peninsula in Michigan and much ...

Does manganese inhaled from the shower represent a public health threat?

...at showering in manganese-contaminated water for a decade or more could have permanent effects on the nervous system. The damage may occur even at levels of manganese considered safe by the Environmental Protection Agency, according to researchers from Wake Forest University School of Medicine. "If our res...

North & South American researchers find architectural abnormalities in T. cruzi ribosome

...st people may not know they have the disease for a decade or more, during which time 20 to 30 percent will develop potentially deadly cardiac problems. According to Levin, there is an urgent need for a more reliable treatment for this chronic phase of the infection. In addition to the public health implica...

Variant prion protein causes infection but no symptoms

... on experimental concepts first developed at RML a decade ago, the research team exposed two groups of 6-week-old mice to different strains of the agent that causes scrapie, a brain-wasting disease of sheep. Within 150 days of being inoculated with the natural form of scrapie prion protein, all 70 mice in t...

Errors in the measurement of global warming corrected

...Celsius (°C) in the average global temperature per decade for the last thirty years. Over the next century, global surface temperatures are expected to increase by 2 to 4°C. However, year-to-year and region to region increases may vary considerably, with a smaller increase in the tropics but 10 degrees or m...

DNA from feathers tells tale of eagle fidelity

... trysts on the sly. In fact, studies over the last decade have shown most broods of socially monogamous birds include offspring from at least two genetic fathers. "Our study actually stands out as a relatively rare instance in which DNA fingerprinting uncovers genetic monogamy in a bird population," DeWood...

Marine bacterium suspected to play role in global carbon and nitrogen cycles

...s like hot springs and deep-sea vents, but about a decade ago molecular studies proved their abundance in more common environs including the open ocean, freshwater and soil. Subsequent efforts to grow various samples of these organisms led to this cultivation of N. maritimus, or "dwarf belonging to the sea...

VCU Massey Cancer Center study shows enzyme linked to spread of breast cancer cells

...ine-1-phosphate in cell growth regulation nearly a decade ago. While researchers know that SphK1 is stimulated by multiple growth factors, less is known about how SphK2 is regulated. Spiegel and her team are continuing this work to better understand the functions of these enzymes. "Our work suggests that s...
