Nanotubes offer new approach to cancer radiotherapy

Radioactive elements, or radionuclides, are well-established anticancer agents whose main limitation is that they kill healthy cells almost as easily as they do tumors. But because nanoparticles can be targeted to tumors, researchers have seized on the idea of using nanoparticles to deliver radionuclides to tumors, thus sparing healthy tissues from radiation-induced damage.

New target for the development of anti-influenza drugs

Scientists at Cure Lab, Inc., a biotechnology company based in Canton, Massachusetts, in collaboration with researchers at Boston University and Harvard Medical School have discovered a potential new target for the development of anti-influenza (flu) drugs, including those that may be effective against potentially pandemic influenza strains like H5N1.

New findings on cholesterol metabolism

A team of researchers investigating cholesterol and lipid transport has performed experiments that cast serious doubt on the dominant hypothesis of how the body rids its cells of "bad" cholesterol (LDL) and increases "good" cholesterol (HDL).

Overexposure to metals and Alzheimer's disease

A multi-institutional team of researchers led by Emory University has defined for the first time how metal ions bind to amyloid fibrils in the brain in a way that appears toxic to neurons.

Potential new ways to prevent smoking-related cellular damage

In the current issue of PLoS One, researchers show how a poorly understood and previously unsuspected mechanism may be the key to understanding how life-style associated forms of oxidative stress, such as exposure to cigarette smoke, damage cells in the lungs.

Vomeronasal organ differentiates male and female behavior in some mammals

For years, scientists have searched in vain for slivers of the brain that might drive the dramatic differences between male and female behavior.

Hip resurfacing may delay hip replacement

In the world of prosthetic hips, what was old is new again. A procedure known as hip resurfacing, once tried two to three decades ago, is experiencing a resurgence in the U.S., thanks to improved technology.

Fear protein found

A University of Iowa study shows that loss or chemical inhibition of a protein, known as acid sensing ion channel protein (ASIC1a), reduces innate fear behavior in lab animals, making normally timid mice relatively fearless.

New weapon in the battle against antibiotic-resistant bacteria

Putting bacteria on birth control could stop the spread of drug-resistant microbes, and researchers at the University of North Carolina at Chapel Hill have found a way to do just that.

Study to investigate how dietary iron is used by cells

A four-year study on iron metabolism within cells, an essential process that impacts both iron deficiency and iron toxicity, conditions responsible for a multitude of human diseases, is underway at the University at Buffalo funded by a $1.16 million grant from the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).
