For the first time, researchers have measured a long-theorized force that operates at distances so tiny they’re measured in billionths of a meter, which may have important applications in nanotechnology as scientists and engineers seek new ways to create devices far too small for the eye to see.
About 10 million people in the United States alone—from troops returning from war to students with music blasting through headphones—are suffering from impairing noise-induced hearing loss.
An experimental anti-cancer drug can prevent — and even reverse — potentially fatal cardiovascular damage in a mouse model of progeria, a rare genetic disorder that causes the most dramatic form of human premature aging, National Institutes of Health (NIH) researchers reported today.
In case anyone was wondering, I am far from alone in my call for a new science policy in the coming administration. It is the topic of the editorial in a recent issue of Science Magazine America’s premier scientific journal.
Other countries, including China, have been investing in science at a good clip. The US is not, costing us our place in world science. The numbers and analysis.
Researchers at the U.S. National Institutes of Health (NIH), McGill University and other institutions have discovered how a simple antiviral drug developed decades ago suppresses HIV in patients who are also infected with herpes. Their study was published in the Sept. 11 issue of the journal Cell Host and Microbe.
AIDS experts say they have compelling evidence that some people with HIV who for years and even decades show extremely low levels of the virus in their blood never progress to full-blown AIDS and remain symptom free even without treatment, probably do so because of the strength of their immune systems, not any defects in the strain of HIV that infected them in the first place.
Scientists have long questioned whether the abundant amounts of amyloid plaques found in the brains of patients with Alzheimer’s actually caused the neurological disease or were a by-product of its progress. Now, using new research techniques, scientists have shown that a two-molecule aggregate (or dimer) of beta-amyloid protein fragments may play a role in initiating the disease.
When smokers kick the habit, odds are they are not alone in making the move. Instead, the decision to quit smoking often cascades through social networks, with entire clusters of spouses, friends, siblings and co-workers giving up the habit roughly in tandem.
New research has shown that the function of a type of cell that helps modulate immune responses is impaired inside tumors in mice. Researchers also identified several factors that may contribute to an accumulation of these cells, called T regulatory cells (Tregs), within and around the tumor, which may be how they respond to their loss of functionality.
A research team supported by the National Institutes of Health (NIH) Roadmap and the National Institute of Allergy and Infectious Diseases (NIAID) has identified chemical compounds that hold promise as potential therapies for schistosomiasis, a parasitic disease that afflicts more than 200 million people worldwide. The findings were reported today in the advance online publication of the journal Nature Medicine.
A brain circuit that underlies feelings of stress and anxiety shows promise as a new therapeutic target for alcoholism, according to new studies by researchers at the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health (NIH).
A new plan to further reduce, refine and replace the use of animals in research and regulatory testing commonly referred to as the 3Rs was unveiled today at a symposium marking the 10-year anniversary of the Interagency Coordinating Committee on the Validation of Alternative Methods (ICCVAM). The plan identifies priority areas for research, development, translation, and validation activities necessary to achieve regulatory acceptance of alternative test methods.
Statement of HIVMA Executive Director Christine Lubinski
The President’s proposed budget for fiscal year 2009, if enacted, would spell disaster for the nation’s health, and by extension, our national effort to respond to the HIV/AIDS epidemic in the United States.
