Helium supplies endangered, threatening science and technology

In America, helium is running out of gas. The uplifting element is being depleted so rapidly in the world's largest reserve, outside of Amarillo, Texas, that supplies are expected to be depleted there within the next eight years. This deflates more than the Goodyear blimp and party favors. Its larger impact is on science and technology, according to Lee Sobotka, professor of chemistry and...

Requiring photo ID has little effect on voter turnout, MU study finds

With the 2008 presidential election less than a year away, many states are working to require photo identification from all voters in an attempt to curb illegal voting. Critics argue that the requirement is unconstitutional and will ultimately reduce participation in elections. However, a recent study of Indiana's photo ID law, conducted by a University of Missouri professor, found that requiring...

Researchers reverse effects of sleep deprivation

Researchers at Wake Forest University School of Medicine have shown that the effects of sleep deprivation on cognitive performance can be reversed when the naturally occurring brain peptide, orexin-A, is administered in monkeys.

Restless legs syndrome doubles risk of stroke and heart disease

People with restless legs syndrome are twice as likely to have a stroke or heart disease compared to people without RLS, and the risk is greatest in those with the most frequent and severe symptoms, according to research published in the Jan. 1, 2008, issue of Neurology, the medical journal of the American Academy of Neurology.

Some antipsychotic drugs may be missing their mark

Drugs that treat depression and schizophrenia might not be triggering the most appropriate response in brain cells, new research suggests. This study examined the early chemical events that happen when a particular serotonin receptor on brain cells is stimulated by serotonin and by a hallucinogenic agent thought to mimic serotonin. The findings show that although both compounds activate this...


If you're feeling helpless, it's best to be alone

If you're going to experience a period of helplessness, it's best to be alone. New research at the University of Haifa found that laboratory rats that were on their own when exposed to uncontrollable conditions, which create a feeling of helplessness, learned to avoid situations which create such feelings better than rats that were exposed to uncontrollable conditions in pairs.


Allergic reactions to gadolinium-based contrast agents are rare, study finds

Allergic-like reactions to gadolinium-containing contrast injections in adults and pediatric patients (those younger than 19 years of age) are rare, according to a recent study conducted by researchers at the University of Michigan Health Systems in Ann Arbor. "When these reactions do occur, most of them are mild," said Jonathan R. Dillman, M.D., lead author of the study.

Cost of glaucoma medications may impact treatment

In the US, management of glaucoma costs about $2.5 billion per year. Of the $1.9 billion in direct costs, glaucoma medications account for an estimated 38 percent to 52 percent of the total. In an article published in the January 2008 issue of the American Journal of Ophthalmology, researchers from Texas A&M University analyzed the economics of medically managing glaucoma. The yearly costs to...

Eltrombopag effective for hepatitis C patients with low blood-platelet counts

For patients with hepatitis C, having a low blood platelet count is a frequent complication associated with advanced disease. This problem is compounded by the fact that standard antiviral treatment for the disease can further reduce platelet numbers to dangerously low levels, effectively denying these patients the treatment they urgently need. Now, research published in the New England Journal of...

LASIK works well, according to long-term study of highly myopic patients

Although over 18 million LASIK procedures have been performed worldwide, there is still some controversy regarding the maximum correction possible and efficacy with this technique. In an article published in the January 2008 issue of the American Journal of Ophthalmology, researchers from Miguel Hernandez University, Medical School and Ankara University School of Medicine report that LASIK for...

Men need more Botox than women

A review published in Dermatologic Therapy reveals that men can be treated with Botox for cosmetic procedures in the same way as women but require higher doses of Botox in all treatment areas.

New ingredients in drug-like anti-aging products improve skin

Cosmecueticals, beauty aids that reportedly work like prescription drugs, are providing new ways to treat aging skin. A study recently published in the Journal of Cosmetic Dermatology explores a variety of new ingredients in cosmeceuticals that provide a visibly noticeable improvement in maturing skin.

New therapy reduces mortality in patients with severe COPD

Patients with severe COPD may benefit more from therapy that combines salmeterol and fluticasone than treatment with tiotropium, according to results from a long-term, multi-center study, "Investigating New Standards for Prophylaxis in Reducing Exacerbations" that directly compared the two therapies.

Pilot error declines as factor in airline mishaps

The number of airline mishaps attributed to pilot error significantly declined between 1983 and 2002, according to an analysis conducted by researchers at the Johns Hopkins Bloomberg School of Public Health. While the overall rate of airline mishaps remained stable during that time, the proportion of mishaps involving pilot error decreased 40 percent. The rate of mishaps related to a pilot's poor...

Public policy fails to address the effects of media violence on children

Highly publicized events such as school shootings arouse public interest in the effects of media violence exposure on children, yet there is still considerable public debate about whether to take this issue seriously. A recent article in Social Issues and Policy Review summarizes the research on the effects of media violence and convincingly demonstrates the profound influence that media violence...

Story ideas from the Journal of Biological Chemistry

Most people wouldn't consider anthrax toxin to be beneficial, but this bacterial poison may someday be an effective cancer therapy. Anthrax toxin has actually been shown to be fairly selective in targeting melanoma cells, although the risk of non-cancer toxicity prevents any clinical use.
