Alcoholism, smoking and genetics among Plains American Indians

... have shown that the Met allele is associated with late onset alcoholism and increased alcohol intake in social drinkers, Enoch and her colleagues have found that in American Indians the Met allele was protective against alcoholism, and the Val allele was the risk allele. "The answer to this paradox ma...

H5N1 avian flu virus vaccine induces immune responses in healthy adults

...inary results from this trial were first disclosed late last summer. "These findings represent an important step forward in the nation's efforts to prepare for the possible emergence of a human pandemic of H5N1 avian influenza," notes NIH Director Elias A. Zerhouni, M.D. "We are working hard to addres...

Cortex matures faster in youth with highest IQ

...hinking circuitry. It also thins faster during the late teens, likely due to the withering of unused neural connections as the brain streamlines its operations. Drs. Philip Shaw, Judith Rapoport, Jay Giedd and colleagues at NIMH and McGill University report on their findings in the March 30, 2006 issue of...

Human trial proves ricin vaccine safe, induces neutralizing antibodies; further tests planned

...not know if they have been exposed until it is too late for treatment, Dr. Vitetta said. Because castor beans are readily available ?more than 50,000 tons of castor bean extract exist around the world as a byproduct of castor oil production ?public health officials warn that ricin could be used for terro...

NASA's AURA satellite peers into Earth's ozone hole

...ne hole shrunk to the size it typically was in the late 1980s. Those years, 2002 and 2004, were the warmest of the period. Scientists also monitor how much ozone there is in the atmosphere from the ground to space. The thickness of the Antarctic ozone layer was the third highest of the last decade, as me...

Argonne researchers confirm lead in Beethoven's illness

His abdominal symptoms and autopsy findings are both consistent with lead poisoning, Walsh said. There have been documented cases of deafness resulting from lead poisoning, but this has b...

New evidence supports century-old theory of cancer spread

...entists worked on it in the 20th century. From the late 1960's up to today there have been many reports of tumor hybrids." "Aichel implored future scientists to study cancer cells 'from all angles' for evidence of hybridization," Pawelek added. "It is remarkable that a century later we are doing just tha...

New research examines genetics of successful aging

...er's disease, the most common cause of dementia in late life. The study also identified novel genetic regions associated with successful aging, including DYS389 and DYS390, some of which affected men or women, but not both. "Historically women have lived longer than men on average, the prevalence of nu...

Seal rookeries could provide a reliable food source for endangered California condors, study finds

...s until Europeans began settling the region in the late 1700s. "In 1806, Lewis and Clark found large condors feeding on whale carcasses near the mouth of the Columbia River in Oregon," Chamberlain notes. "But huge sealing and whaling industries started around that time, and the large seal rookeries and wh...

The bioweapon is in the post

The US National Science Advisory Board for Biosecurity, set up last year to advise the US government on which advances in biology could be exploited by terrorists, is also considering the issue. Some gene synthesis companies say they would wel...

Overfishing may drive endangered seabird to rely upon lower quality food

Finding rewrites the evolutionary history of the origin of potatoes

"As a taxonomist, my job is to help determine what is a species and to classify those species into related groups," Spooner explains. "Other scientists use...

First big influenza genome study reveals flu evolution

...ant strain. This reassortment yielded a new strain late in the season. The new strain quickly won out, becoming the dominant virus in the 2003-04 flu season. Because scientists had not factored this latecomer strain into the '03-04 vaccine, however, the vaccine was less effective. Genomics turns a new sp...

Plants have a double line of defence

...so other pests ?for example, the pathogens causing late potato blight. PEN2 is therefore a basic component of the plant's immune system with a broad range of effects. However if PEN2 is missing, the plant is not completely helpless against fungal diseases. There is still another line of defence which the...

Male elephants woo females with precise chemistry

Young males secreted significantly more of the "plus" frontalin than "minus," but the ratios became almost equal as the elephant matured, especially between ages 31 and ...

MIT researcher finds neuron growth in adult brain
