In the line of fire
Nuclear missiles targeted at US cities and intercepted by Bush's proposed missile defence shield could still explode over Europe, Canada or middle America instead.

Seizure treatment en route to hospital safe and effective, study shows
Potentially life threatening seizures can be safely treated by paramedics using injections of Valium or similar benzodiazepine drugs en route to the hospital, rather than waiting for hospital staff to administer the drugs, according to a new study led by researchers at the University of California, San Francisco.

Illicit abortion drug causes birth defects
Failed attempts to induce abortion with an ulcer drug called misoprostol may be causing a minor epidemic of birth defects.

Plastic is forever -- or not
Once materials are joined to create a polymer, or plastic, the molecules are traditionally irreversibly linked.

New technology treats dairy wastes, odors
A technology brought to the Northwest by researchers at the Department of Energy's Pacific Northwest National Laboratory is transforming a waste lagoon into a waste treatment facility at a Washington state dairy.

Experiment provides new clues to the location of visual consciousness
A new test that measures what people see when viewing discordant images in the right and left eyes has produced important new clues about the location of some of the brain activity underlying visual consciousness.

Researchers improve thermal stability of fuel cell materials
One of the limiting features of fuel cells involve the characteristics and stability of polymeric materials used in the proton exchange membrane (PEM).

Safe effective treatment to stop seizures can be delivered outside of the hospital
A new study shows that paramedics can safely and effectively treat patients who are suffering from acute and prolonged seizures with injections of benzodiazepines, a mild form of tranquilizers.

New research shows workplace homicides more likely at smaller businesses open late, Saturdays
Smaller businesses, businesses that opened at their current locations within the past two years and businesses having only one worker on duty evenings and weekends are more likely than other workplaces to experience homicides, a new University of North Carolina at Chapel Hill study shows.

Genes that dictate metabolic processes in an ancient life form being identified by Virginia Tech biochemist
Scientists who want to know about the origin of life often study Archaea, bacteria that evolved from the earliest form of life at least 2 billion years ago.

New antimalaria drug succeeds in first animal tests
Researchers at Johns Hopkins have designed a new drug for malaria that has easily passed the first stage of preclinical testing in mice and rats.

New epilepsy gene identified in mice
HHMI researchers have identified a novel gene that is mutated in mice that develop spontaneous epileptic seizures in response to loud noises.

T cell responses in aplastic anemia
Immunosuppressive drugs generally lead to substantially improved blood cell counts in individuals with aplastic anemia (AA), a severe decline of all blood cell lineages in which the marrow is deficient in hematopoietic cells.

Fight between GMOS and the bugs they repel may not be over
Mark Whalon, a Michigan State University entomology professor, says that farmers and those marketing genetically modified seeds shouldn't become complacent because so far there has been no documented evidence that insects have developed resistance to crops engineered to repel them.

Balls stick, shoes slide: Serving up tennis court physics
A physics professor at the University of Sydney is looking into some of the peculiar properties of clay tennis courts - which may explain why players like Jennifer Capriati are able to triumph on clay courts, but may stumble on grass.

Laser technique examines movement in nucleus of living cell
By colliding two laser beams head-on, scientists at the University of Illinois can measure the movement of chromatin (tiny packets of DNA) in the nucleus of a living cell.

Dentists abuzz over cavity-prevention potential of honeybee product
Dentists have discovered that a substance that Brazilian honeybees make to protect their hives might prove to be a potent anti-cavity agent.

Flaxseed may fight breast cancer in postmenopausal women
Flaxseed, sold in health food stores as a dietary supplement, may protect postmenopausal women against breast cancer, according to a new study by researchers at the University of Minnesota in St.

Chemists increase conductivity of fuel cell materials
At the heart of modern fuel cells are proton exchange membrane (PEM), through which hydrogen protons pass to meet oxygen and generate electrochemical energy.

DNA vaccination places tumors in double jeopardy
The ER resident chaperone protein calreticulin plays a surprising variety of roles in cell regulation, some of which make it particularly appealing for antitumor vaccination.

New dinosaur expert publishes in Nature
An extremely well-preserved fossil found by Peter Makovicky - the Field Museum's new dinosaur expert - sheds light on what an ostrich-like dinosaur ate and where it lived.

Rutgers researchers find black tea 'bullet' that targets colorectal cancer
A team of Rutgers researchers has found a compound in black tea that appears to be one of the

Discovery of a unique gene modification may provide clues to the cause of certain types of lymphoma, UCLA researchers say
Researchers at UCLA's Jonsson Cancer Center have discovered a unique gene modification in adult human cancer cells that could provide insight into the cause of certain types of lymphoma and possibly other cancers, according to research published Aug.

Chemists use statistics to improve creativity
Using combinatorial and in-parallel experimentation techniques accelerates creativity and allows researchers to make discoveries more quickly.

An excess of healthy cells holds leukemia in check
In one useful model of juvenile myelomonocytic leukemia (JMML), lethally irradiated mice receive hematopoietic cells from the liver of a fetal mouse lacking the growth-inhibiting protein NF1.

Earth's light show is a clue to finding habitable neighbors
Viewed from a star in some other corner of the galaxy, Earth would be a speck, a faint blue dot hidden in the blazing light of our sun.

Study provides new evidence that chemical in tomato sauce may help fight prostate cancer, particularly in black men
A new study involving African-American men -- who as a group have the highest incidence of prostate cancer in the world -- provides further evidence that lycopene, a chemical found in abundance in tomato sauce, may help prevent or slow the development of the disease.

Age of menopause dictated largely by genes
The age at which a woman reaches menopause is 85% genetically determined, according to new research by Dutch fertility experts published in Europe's leading reproductive medicine journal, Human Reproduction.
