Unknown 'root' extension in hair cells of the inner ear

The hair cells of the inner ear have a previously unknown "root" extension that may allow them to communicate with nerve cells and the brain to regulate sensitivity to sound vibrations and head position, researchers at the University of Illinois at Chicago College of Medicine have discovered. Their finding is reported online in advance of print in the Proceedings of the National Academy of Sciences.

Blood vessels that form within brain cancers predominantly not made up of cancer cells

Johns Hopkins scientists have published laboratory data refuting studies that suggest blood vessels that form within brain cancers are largely made up of cancer cells. The theory of cancer-based blood vessels calls into question the use and value of anticancer drugs that target these blood vessels, including bevacizumab (Avastin).

Five new genetic mutations linked with Crohn's disease in Ashkenazi Jews

In the largest study of its kind, researchers from Mount Sinai School of Medicine have discovered five new genetic mutations associated with Crohn's disease in Jews of Eastern European descent, also known as Ashkenazi Jews.

Study uncovers critical process in understanding degeneration of brain cells sensitive to AD

A research group led by Dr. A. Claudio Cuello of McGill University's Faculty of Medicine, Dept. of Pharmacology and Therapeutics, has uncovered a critical process in understanding the degeneration of brain cells sensitive to Alzheimer's disease.

New vaccination strategy may effectively eradicate HIV-1 infection

In what may prove to be a major step forward for the treatment of HIV-1 infection, scientists have discovered an effective way to eliminate a notoriously persistent form of the virus that does not respond to current therapies. The research, published online by Cell Press on March 8th from the journal Immunity, describes a vaccination strategy that may be essential for successful eradication efforts and should therefore be considered for future clinical trials.

Even low-dose nanoparticles could have big impact on long-term health

Nanoparticles are everywhere. From cosmetics and clothes, to soda and snacks. But as versatile as they are, nanoparticles also have a downside, say researchers at Binghamton University and Cornell University in a recent paper published in the journal Nature Nanotechnology. These tiny particles, even in low doses, could have a big impact on our long-term health.

Genetically modified pig may hold keys to develop treatments for RP

A newly developed, genetically modified pig may hold the keys to the development of improved treatments and possibly even a cure for retinitis pigmentosa (RP), the most common inherited retinal disease in the United States.

HDAC inhibitors flush latent HIV infection from hiding

A team of researchers at the University of North Carolina at Chapel Hill have successfully flushed latent HIV infection from hiding, with a drug used to treat certain types of lymphoma.

Biologists identify how and where the brain processes FM sweeps

In both animals and humans, vocal signals used for communication contain a wide array of different sounds that are determined by the vibrational frequencies of vocal cords. For example, the pitch of someone's voice, and how it changes as they are speaking, depends on a complex series of varying frequencies. Knowing how the brain sorts out these different frequencies-which are called frequency-modulated (FM) sweeps-is believed to be essential to understanding many hearing-related behaviors, like speech.

New hybrid aspirin shrinks tumors, curbs cancer cell growth

The humble aspirin may soon have a new role. Scientists from The City College of New York have developed a new aspirin compound that has great promise to be, not only an extremely potent cancer-fighter, but even safer than the classic medicine cabinet staple.

Moderate wine intake appears to have favorable effect on lung function

A research team from the Netherlands assessed the impact of wine and resveratrol (a natural polyphenol found in high quantities in red wine) on lung function. It also looked at genetic factors and mechanisms by which resveratrol might be absorbed by the body and its possible effect on longevity of life.

Researchers identify specific gene linked with throat cancer

Researchers at King's College London and Hiroshima University, Japan, have identified a specific gene linked to throat cancer following a genetic study of a family with 10 members who have developed the condition.

First ever analysis of genetic variation between different regions of same tumour

Taking a sample from just one part of a tumour may not give a full picture of its 'genetic landscape', according to a landmark study published in the New England Journal of Medicine.

MRF clinical trial to examine antigen-specific MS therapy

The Myelin Repair Foundation (MRF) announced today that its research might soon lead into a clinical proof-of-concept trial at the Department of Neuroimmunology and Multiple Sclerosis Research (nims), University Hospital Zürich, Switzerland, and the Institute for Neuroimmunology and Clinical Multiple Sclerosis Research (inims) in Hamburg, Germany.

CB2 receptor involved in regulating impulsive behaviour

A new study lead by the Neuroscience Institute of Alicante reveals how manipulating the endocannabinoid system can modulate high levels of impulsivity. This is the main problem in psychiatric illnesses such a schizophrenia, bipolar disorder and substance abuse.
