Volcanic eruptions may affect El Niño onset
A new study by scientists at the University of Virginia (UVa) in Charlottesville and the National Center for Atmospheric Research (NCAR) in Boulder, Colorado, suggests that explosive volcanic eruptions in the tropics may increase the probability of an El Niño event occurring during the winter following the eruption.

Lewis and Clark notes reveal history of human impacts
Native Americans had a major impact on the wildlife of the American West for hundreds of years prior to European settlement, a report from Oregon State University indicates, based on data from the journals of Lewis and Clark.

Study unearths cliques in the food web
Cliques aren't solely a high school phenomenon - they also exist in the food chain, and offer a way of better managing ecosystems.

Welfare recipients will not seek help if it is too far away, study says
The closer a welfare recipient resides to mental health and substance abuse providers, the more likely the person is to seek those services, according to a new Brown University study.

Experimental drugs reduce neuron death in rats following insulin shock
In a study conducted in rats, scientists have determined that drugs that block the action of a group of DNA-repair enzymes can protect brain cells from damage triggered by an overdose of insulin.

New drug target and biomarker for advanced childhood cancer discovered
Scientists announced today that they have discovered a protein produced by advanced childhood cancers that provides a new target for treatments and a new marker for the disease.

New nanoscience centre to make Montreal world leader
Nanotechnology research, the science of miniaturizing through ultra-sophisticated machinery, has obtained globally competitive headquarters at McGill University in Montreal.

National Science Board releases workforce report with new sense of urgency
The National Science Board (NSB) today released a report on the U.S. science and engineering (S&E) workforce following a three-year study, saying that new figures on the proportion of foreign-born workers in science and technology occupations make it crucial for the government to

Biofilm antibiotic resistance may be susceptible to genetic approach
Biofilms, slimy clusters of bacteria that are resistant to antibiotics, may have a genetic chink in their armor that could be exploited to combat the infections they cause.

High pollution may increase SARS death rate
Air pollution is associated with an increased risk of dying from SARS, according to a report published this week in Environmental Health: A Global Access Science Source.

UT Southwestern researchers learn importance of insulin family signaling in male sex determination
Researchers at UT Southwestern Medical Center at Dallas have shown that insulin family signaling is important for male sex determination, a discovery that furthers the understanding of testes formation and eventually could lead to treatments for reproductive disorders.

Proteins may help identify patients who will respond better to treatments in certain cancers
Scientists today presented studies of proteomic and genomic markers that could help oncologists devise better treatment approaches for specific patients, and may improve clinical outcomes.

SARS death rate doubles in polluted cities
A new study led by researchers at the UCLA School of Public Health shows that patients with SARS are more than twice as likely to die from the disease if they come from areas of high pollution.

Focus on solar outbursts
While scientists and aurora spotters marvel at the explosions on the Sun, everyone responsible for the hundreds of satellites that serve human needs, from weather observations to car navigation, wishes that these potentially damaging events were more predictable.

Gliomas' 'molecular fingerprint' predicts how aggressive tumor will be
The most common form of primary brain tumor - glioma, affecting about 25,000 Americans each year - poses a dilemma for doctors and patients trying to make decisions about treatment.

Jefferson scientists find radiation and blood vessel inhibitor more effective against brain tumors
Combining radiation with an agent that blocks VEGF, a protein that promotes the development of blood vessels and the growth of cancerous tumors - a process known as angiogenesis - may be more effective against brain tumors than either treatment alone, researchers at Jefferson Medical College have found.

Leading the way in novel anti-cancer research
New research presented today at an official AACR-NCI-EORTC* press conference highlights the potential of a new approach to fighting cancer -- inhibition of Aurora kinases.

UCF to help lead new research institute at Kennedy Space Center
