Drunken Fruit Flies Help Scientists Find Potential Drug Target For Alcoholism

Posted: 07 Nov 2009 02:00 PM PST

Drunken fruit flies have helped researchers identify networks of genes -- also present in humans -- that play a key role in alcohol drinking behavior. This discovery provides an indication of why some people seem to tolerate alcohol better than others, and points toward a potential target for drugs aimed at preventing or eliminating alcoholism.

1930s Drug Slows Tumor Growth: Gonorrhea Medication Might Help Fight Cancer

Posted: 07 Nov 2009 02:00 PM PST

Drugs sometimes have beneficial side effects. A glaucoma treatment causes luscious eyelashes. A blood pressure drug also aids those with a rare genetic disease. The newest surprise discovered by researchers is a gonorrhea medication that might help battle cancer.

New Computer Simulator Helps Design Military Strategies Based On Ants' Movements

Posted: 07 Nov 2009 02:00 PM PST

Researchers in Spain have designed a system for the mobility of military troops within a battlefield following the mechanisms used by ant colonies to move. The scientists have used settings of Panzer General, a commercial war video game, for the development of this software.

New Way To Attack Inflammation In Graves' Eye Disease

Posted: 07 Nov 2009 02:00 PM PST

A small group of patients with severe Graves' eye disease experienced rapid improvement of their symptoms -- and improved vision -- following treatment with the drug rituximab. Inflammation around their eyes and damage to the optic nerve were significantly reduced. The same patients had not previously responded to steroids, a common treatment for Graves' eye disease.

Magnetic Nanoparticles To Simultaneously Diagnose, Monitor And Treat

Posted: 07 Nov 2009 02:00 PM PST

The future for magentic nanoparticles (mNPs) appears bright With the design of "theranostic" molecules. Magentic nanoparticles could play a crucial role in developing one-stop tools to simultaneously diagnose, monitor and treat a wide range of common diseases and injuries.

New Transcranial Magnetic Stimulation (TMS) Clinic Offers Noninvasive Treatment For Major Depression

Posted: 07 Nov 2009 02:00 PM PST

Rush University Medical Center has opened the Transcranial Magnetic Stimulation (TMS) Clinic to offer patients suffering from major depression a safe, effective, non-drug treatment. TMS therapy is the first FDA-approved, non-invasive antidepressant device-based treatment clinically proven for treatment of depression. Psychiatrists at Rush University Medical Center were among the first to test the technique and Dr. Philip Janicak, professor of psychiatry and lead investigator at Rush for the clinical trials of TMS, helped to develop this therapy.

Computational Method Points To New Uses, Unexpected Side Effects Of Already Existing Drugs

Posted: 07 Nov 2009 08:00 AM PST

Scientists have developed and experimentally tested a technique to predict new target diseases for existing drugs. The researchers developed a computational method that compares how similar the structures of all known drugs are to the naturally occurring binding partners -- known as ligands -- of disease targets within the cell.

Air Pollution Increases Infants' Risk Of Bronchiolitis

Infants who are exposed to higher levels of air pollution are at increased risk for bronchiolitis, according to a new study.

Hybrid Composite For Root Canal Treatment

Posted: 07 Nov 2009 08:00 AM PST

A dentist carrying out root canal treatment will need to use a variety of compounds. These do not always bond together properly and sometimes expensive follow-up treatment has to be performed. But a new class of material meets the requirements, and solves the problem.

The Skeleton: Size Matters; New Role For Master Patterning Genes In Defining Number Of Vertebrae In Spine

Posted: 07 Nov 2009 08:00 AM PST

It has long been known that the identity of each vertebra is due to the activation of a class of genes called "Hox." Now, researchers in Portugal show that besides determining the identity of the vertebrae, Hox genes also have a say in how many are going to be formed at all.

Capturing Those In-between Moments: Timing Problem In Molecular Modeling Solved

Posted: 07 Nov 2009 08:00 AM PST

A theoretical physicist has developed a method for calculating the motions and forces of thousands of atoms simultaneously over a wider range of time scales than previously possible. The method overcomes a longstanding timing gap in modeling nanometer-scale materials and many other physical, chemical and biological systems at atomic and molecular levels.

Most Parents, High-priority Adults Who Tried To Get H1N1 Vaccine For Themselves And Children Unable To Get It, Poll Finds

Posted: 07 Nov 2009 08:00 AM PST

A new national poll has found that a majority of adults who tried to get the H1N1 vaccine for themselves or their children have been unable to do so.

Hormone That Affects Finger Length Key To Social Behavior

Posted: 07 Nov 2009 02:00 AM PST

Research in the UK into the finger length of primate species has revealed that cooperative behavior is linked to exposure to hormone levels in the womb.

Hunting For The Prozac Gene

Posted: 07 Nov 2009 02:00 AM PST

Scientists are working to find a genetic marker to determine the effectiveness of Prozac and other SSRIs before they are prescribed.

Boosting Coastal Economics With Crustacean Molting On Demand

Posted: 07 Nov 2009 02:00 AM PST

Researchers are close to unraveling intricate cellular pathways that control molting in blue crabs. The discoveries could revolutionize the soft-shell crab industry, generating new jobs and additional profits for the US fishing industry along the coastal Southeast.
