When the parents of children diagnosed with chronic illnesses were asked about non-supportive and hurtful behaviors from relatives, friends and health-care providers, they said more than a third of such incidents came from those they most expected to help -- doctors and other health professionals.

Study Identifies Level Of Vision That Alters Child's Development
Researchers at the universities of North Carolina at Chapel Hill and North Colorado have discovered that development in children whose visual acuity was 20/500 or better was significantly better than the development of children whose visual acuity was 20/800 or worse.

Ice-Comet Debate Continues: Review Of Data Indicates That The Cause Is Noise
A constant rain of comets pelting the Earth probably is just noise common to many scientific instruments, according to a scientist at NASA's Marshall Space Flight Center.

Imagination Can Enhance Visual Perception: Weizmann Scientists Reveal Windows On Your Mind
Bringing up images from short-term memory enhances our ability to see what's really there, Weizmann Institute scientists report in the current issue of the Journal of Cognitive Neuroscience.

Earthquake News From The AGU Meeting
At the annual meeting of the American Geophysical Union, geologist Roland Burgmann of the University of California, Davis, will discuss several new studies of fault activity in the San Francisco Bay Area and around the world.

Atmospheric Sprites May Have Streamer Structure
Red sprites ­ the dazzlingly bright but subliminally brief form of lightning that occurs high in the atmosphere above large thunderstorms ­ may not be the amorphous blobs of light that scientists had first thought.

Earth Weaves Its Own Invisible Cloak - Earth's Own Polar Fountains Fill Magnetosphere With Ions
Since the late 1950s and '60s, scientists have believed that the Earth's magnetic field has captured a lot of the solar wind - charged particles flowing out from the sun - and formed an immense, comet-like cloud of electrified gas that surrounds our planet.

Off The Cuff: Pulse Pressure Serves As Marker For Heart Disease Death
A novel form of blood pressure reading can be a strong predictor of coronary heart disease death, according to a study reported by a Paris team of researchers in this month's Hypertension, an American Heart Association journal.

Premies' Lung Disorder Can Cause Developmental Delays
Investigators from Case Western Reserve University's School of Medicine found that a significant percentage of very low birthweight babies sustain long-term developmental problems if they suffer from a lung disease caused by prolonged exposure to mechanical ventilation, which premies need because of underdeveloped lungs.

Enterotoxemia Type D Vaccination Of Lambs
Young lambs may not need inoculation against enterotoxemia type D -- otherwise known as

Discovery Links New Form Of Inheritance In Yeast To
Chicago researchers have discovered that a chaperone protein from yeast can regulate the folding not only of yeast but also mammalian prions, providing therapeutic targets for diseases like

Researchers Declare War(Farin) On Stroke
Although the drug warfarin prevents up to 80 percent of strokes suffered by those who have atrial fibrillation, which is irregular heart beat, it is woefully underused in the patients who have this common heart condition, according to a study in this month's Stroke, a journal of the American Heart Association.

Tracking Free Radicals To The Site Of Action
The power of an innovative method to directly measure the damaging activity of free radicals in the body was further confirmed in a recent study from the University of Pennsylvania Medical Center.

Giant Snowballs In Space? No, Says Researcher, They're Simply Black Snow On The TV Screen
Last May University of Iowa space physicist Louis Frank claimed to have discovered 20- to 40-ton cosmic snowballs, the size of houses, pelting the Earth at the rate of 30,000 a day.

First Tissue-Engineering Experiment In Space A Success, Scientists Report
Thanks in part to a diligent astronaut and several million bovine cartilage cells, MIT and NASA scientists report that the first tissue-engineering experiment in space was a resounding success.

U.S. EPA Provides $7.5 Million To Establish Drinking Water Research Center At University Of Cincinnati
The United States Environmental Protection Agency will provide $7.5 million over the next five years to support a new national drinking water research center at the University of Cincinnati.

7-Day Exercise Program Cuts Insulin Resistance In African-American Women
After only seven days of physical activity -- walking or stationary biking -- women with high blood pressure began to reap dramatic health benefits, according to a report in this month's Hypertension, a journal of the American Heart Association.

Homeobox Gene Siamois Linked To Master-Control Cells In Early Embryo
A University of Pennsylvania Medical Center researcher has found that the homeobox gene siamois is required for the formation of master-control cells that govern the identity and arrangement of embryonic cells.

Innovations In Research Threatened By Proposals To Restrict Exchange Of Data Among Scientists
Research towards a cure for AIDS, predicting global climate change, and mapping the Human Genome may be hampered by efforts underway to restrict the use of scientific data, according to the American Association for the Advancement of Science (AAAS).

Biogenic Emissions Higher Than Expected Over African Savanna
Air-pollution-related hydrocarbon emissions from vegetation are much higher than expected over the African savanna (flat tropical grasslands), while those coming from the rain forests are somewhat lower than prior estimates, according to scientists.

Transgene Research Yields New Information On Prenatal Role Of Blood Coagulating Protein
Surprising results of recent transgene research indicates that the coagulation protein known as Tissue Factor plays a role in embryonic development that does not involve the related coagulation protein, Factor VII.

Amazing Underwater World Emerges From New Data, UD Researcher Says
A detailed portrait of the Southwest Indian Ridge (SWIR)--the boundary between the slowly spreading Antarctic and African plates--reveals the steepest underwater cliff ever recorded and may shed new light on the origins of primitive life forms, John Madsen, University of Delaware geologist, reported today at the American Geophysical Union meeting in San Francisco.

Cadherin Knockout Reveals Molecule's Role In Growth And Differentiation
Studies with a P-cadherin knockout mouse are giving University of Pennsylvania Medical Center scientists a better understanding of the role of cell-adhesion molecules as checks on cellular growth and differentiation.
