Testosterone -– the hormone responsible for a man’s sex drive -– may help him recover from a stroke, according to preliminary animal research at Saint Louis University.
Researchers will present their findings at the annual meeting of the American Neurological Association in October. “It looks like testosterone speeds up the recovery from a stroke,” said Yi Pan, M.D., Ph.D., assistant professor of neurology at Saint Louis University School of Medicine and principal investigator
University of York finds ’real life’ is key to learning
Secondary schoolchildren are far more positive about science if they are taught how it relates to real life, University of York researchers have discovered. For example, if they are learning about forces and motion, they might begin by looking at what happens when they ride a bicycle. Films and news stories about cloning might help them to explore ideas about genes and heredity.

Telos/Omnia and Fraunhofer IIS announce the first public demonstration of their new surround system for HD Radio™ at the NAB Radio Show in San Diego, October 6-8, booth 907.
At NAB Radio Show, Telos/Omnia and Fraunhofer IIS present a novel surround system for HD Radio™ delivering impressive full surround audio without compromising the stereo signal in any way. This way, both users equipped with conventional stereo receivers and those owning surround receivers will get the maximum aud
In Britain, 900,000 adults are stalked every year. It’s a crime that devastates lives. Stalking behaviour can lead to assault, rape and in some cases murder. All too often those affected are left to suffer in silence.
For the first time ever, global stalking victims are being given a voice. The University of Leicester and the Network for Surviving Stalking [NSS] are embarking on the most comprehensive study of those affected by the crime.
The researchers aim to find out vi
Why is it that all the volcanic activity in the United States is targeted in the Northwest? Could such activity that we are now witnessing with Mount St. Helens in Washington happen on the East Coast?
That isn’t likely to happen anytime soon–even by geological standards–since the geological conditions on the East Coast lack key conditions necessary for volcanic activity, says R.J. Tracy, professor of geosciences at Virginia Tech.
According to Tracy, the following c
Rice study probes basic science related to Alzheimer’s, other diseases
Patients suffering from diseases as varied as Type II diabetes, Alzheimer’s, Parkinson’s and dozens of lesser known maladies have one thing in common: they suffer from a large build up of amyloids, tissue that’s created when millions upon millions of misfolded proteins stick together and form a mass that the body can’t get rid of on its own. Doctors don’t yet understand whether amyloids cause disease or result f
Boosting the blood count – in effect, curing anemia – in conjunction with radiation therapy won’t help patients with head and neck cancer fare any better than with radiation alone, says a national study led by Jefferson Medical College researchers. Physicians have known for decades that patients who have anemia and are undergoing radiation therapy, especially for head and neck cancer, do much worse in terms of controlling their cancer and survival.
One theory proposes that anemia
Mayo Clinic neurologists have discovered a drug application smart enough to alleviate orthostatic hypotension — problems with sinking blood pressure when standing up from a sitting position — without the unwanted effect of also causing patients’ blood pressure to soar when lying down.
“This is a significant step forward for these patients,” says Phillip Low, M.D., Mayo Clinic neurologist and lead study investigator. “This would be a good drug to provide the first line of trea
Scientists have made significant progress in developing an animal model of smallpox that closely resembles human disease, which will be necessary for testing of future vaccines and potential treatments.
The study, published in this week’s online early edition of Proceedings of the National Academy of Sciences, is the first to demonstrate that variola virus, the causative agent of smallpox, can produce lethal disease in monkeys.
Smallpox, a devastating disease, was er
Spitting into a cup or licking a diagnostic test strip could someday be an attractive alternative to having your blood drawn at the doctor’s office. Researchers have identified the largest number of proteins to date in human saliva, a preliminary finding that could pave the way for more diagnostic tests based on saliva samples. Such tests show promise as a faster, cheaper and potentially safer diagnostic method than blood sampling, they say.
“There is a growing interest in saliva a
A prescription cream recently approved to treat select superficial basal cell carcinomas (sBCCs) may provide an alternative to skin surgery in certain cases. The FDA approved 3M’s Aldara (imiquimod) in July.
Dermatologist Craig Elmets, M.D., one of the investigators in its clinical trials, says imiquimod will be “useful for treating patients in whom surgical procedures are difficult, including elderly patients, patients with sBCCs at cosmetically sensitive areas where scarring is a concern,
A recent study, published in the Journal of Vertebral Subluxation Research, describes a 19-year old female diagnosed with General Anxiety Disorder (GAD) who suffered from somatic and psychiatric symptoms for two years. After a four-month course of chiropractic care, the young woman reported an 80% reduction in her anxiety symptoms, including a 90% decrease in her headaches. The patient was able to resume a normal lifestyle without resorting to prescription or over-the-counter drugs.
Minor depression, an underdiagnosed and undertreated subset of major depressive disorder that affects upwards of 15 million Americans*, can be effectively treated with a drug called a selective serotonin reuptake inhibitor (SSRI), according to a multi-center study led by the University of California, San Diego (UCSD) School of Medicine and published in the October 2004 issue of the American Journal of Psychiatry.
“This is especially important since patients with minor depression are n
The University of North Dakota (UND) Energy & Environmental Research Center (EERC) has successfully generated electricity from biomass with an exciting, cost- effective gasification technology in a diesel engine. Biomass includes forest residues, wood chips, sawdust, and agricultural by-products.
This fall, the EERC has completed over 100 hours of continuous operation of a biomass gasifier firing wood chips. The process converts wood chips into gas (similar to natural gas) that can be
An asteroid 2.9 miles long and 1.5 miles wide zoomed past Earth Sept. 29 and came within 962,951 miles of the planet. While this might not seem like a near miss, technically it is relatively close – merely four times the distance between Earth and the moon.
But, it’s not likely that a large space rock like this one would actually hit Earth in our lifetime, says physics professor Perry Gerakines, Ph.D. “The odds that an asteroid of this magnitude would impact the Earth are in the millions t
As a result of fossil fuel emissions, many freshwater bodies in eastern North America have become acidified. When combusted, fossil fuels release sulfur dioxide and nitrogen oxide, the precursors to acid precipitation, into the atmosphere. Persistent exposure to these pollutants, which return to Earth in rain, snow, sleet, hail and fog, can compromise the health of aquatic ecosystems.
