New nanoprobe imaging station helps study the distribution of elements in cells

Scientists suspect that iron accumulation plays a role in neurodegenerative processes such as Parkinson's disease, but its distribution in neurons has never been observed because of the lack of techniques to do so. Until today.

Research shows how genetic mutation causes epilepsy in infants

New research from the Howard Florey Institute in Melbourne has shown why mutation in a single gene can cause epilepsy in infants.

Mutations in the insulin gene can cause permanent neonatal diabetes

Mutations in the insulin gene can cause permanent neonatal diabetes, an unusual form of diabetes that affects very young children and results in lifelong dependence on insulin injections, report researchers from the University of Chicago and Peninsula University (Exeter, UK) in Sept. 18, 2007, issue of the Proceedings of the National Academy of Sciences, published early online.

Nanotechnology helps identify molecular signature common to Lou Gehrig's disease

A nanotechnology developed by a University at Buffalo professor has enabled researchers to identify a molecular signature common to both familial and sporadic cases of amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease.

A drug-sensitive 'traffic cop' tells potassium channels to get lost

Our brains are buzzing with electrical activity created by sodium and potassium ions moving in and out of neurons through specialized pores. To prevent the constant chatter from descending into chaos the activity of these ion channels has to be tightly regulated.

Small animal imaging facility is big boon to research

When powerful magnets line up the body's protons before radiofrequency waves can grab their attention away, it's called spin physics.

Neurotransmitter current not flowing through ion channels

In studying how neurotransmitters travel between cells -- by analysis of events in the dimensions of nanometers -- Cornell researchers have discovered that an electrical current thought to be present during that process does not, in fact, exist.

Scientist uses novel mass spectrometer to weigh virus particle

With unprecedented sensitivity, Carnegie Mellon University's Mark Bier has characterized large viral particles and bulky von Willebrand factors using a novel mass spectrometer.

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.
