Mayo Clinic Jacksonville scientists show that specially created molecules can cross blood-brain barrier
Mayo Clinic Jacksonville scientists have shown that a specially created molecule injected into the belly of a rat can cross the nearly impassable blood-brain barrier and can stop the chemical reaction in the brain that the molecule was designed to impede.

Technology lifts-off in time for new space shuttle
A new composite curing technology that uses high energy electron beams is set to allow composite materials to take centre stage in the development of new aerospace vehicles, such as the proposed Joint Strike Fighter (JSF) aircraft and the space shuttle replacement, Venture Star.

Spy flies
A biologist from the University of California Berkeley, sponsored by the Office of Naval Research and the Defense Advanced Projects Agency, has identified the principles that explain not only how insects stay aloft, but also how they steer and maneuver.

Technotes -- Pacific Northwest National Laboratory's summer news tipsheet
Research highlights from Pacific Northwest National Laboratory.

Transmitting infertility from father to son
Genetic studies at the Whitehead Institute for Biomedical Research have shown that some boys will be infertile as adults because they have inherited a genetic defect from their fathers through a commonly used method of assisted reproduction known as intracytoplasmic sperm injection (ICSI).

Clues to heart disease seen in cholesterol reactions to stress
Healthy young men whose mothers and/or fathers suffered heart attacks react to major stressors with elevated blood levels of cholesterol and other lipids that may predict cardiovascular illness and death, new research shows.

Blue light special
Emerging technology to produce commercially viable solid- state lasers capable of emitting light in the blue segment of the color spectrum is well on its way thanks to ONR-funded research.

Hopkins study shows new target for boosting the immune system to improve cancer vaccines
Cancer scientists at the Johns Hopkins Oncology Center have figured out a way to keep the body's cancer-fighting immune cells awake and responsive to tumor cells far longer than they normally do.

A picture worth a thousand megabytes
A new system will allow high-speed visualization of three- dimensional data at a fraction of the cost of supercomputers.

Smart masts for intelligent yachts
An intelligent yacht mast that can sense the potentially catastrophic stresses and strains caused by high winds has been developed by embedding fibre-optics to provide sailors and engineers with a real-time picture of the stresses being placed on the yacht.

Agronomists offer alternative approaches to gulf pollution
Modifying tile drainage systems and crop rotations in farmer's fields are the best methods to prevent nitrates from fertilizer from leaking off farms and into nearby streams, say two Purdue University agronomists.

Information technology is key to decreasing surgery costs, UI researcher finds
Managed care has made controlling health care costs crucial. Some economists have suggested achieving financial savings in the operating room by having patients wait longer for elective surgery.

Antibiotics-resistant bacteria
DNA becomes remarkably organized in bacteria that are subjected to various conditions of stress, Weizmann Institute scientists report in the July 1 issue of Nature.

Mayo clinic researchers explore new methods to detect Parkinson's disease in at-risk individuals
Mayo Clinic neurologists are using existing technology and an investigational drug to detect pre-symptomatic Parkinson's disease in at-risk people who have family members with Parkinson's disease.

Noise reduction
A new system developed by Hood Technology of Hood River, Ore. through the Navy's Small Business Innovation Research program controls interior noise and vibration, especially in propeller-induced sound within turbo-prop aircraft.

New study finds African-Americans less likely to receive stroke-saving surgery
African-Americans are less likely than Caucasians to undergo an important surgery designed to prevent stroke, according to a study published in this month's Stroke: Journal of the American Heart Association.

Fathers pass infertility to sons
Men with reduced sperm counts caused by a specific genetic defect can have children via in vitro fertilization, but a new study by HHMI researchers suggests that the sons of these men may also develop infertility.

Database technology threatens liberty
The U.S. House of Representatives will be voting on a bill gutting medical privacy.

Bomb fallout helps pinpoint soil carbon dioxide
A long-term study has found that while trees take up in their tissues substantial amounts of the excess carbon dioxide that contributes to global warming, the accumulation of carbon into soils may be relatively slow.
