New research suggests that the form of tomato product one eats could be the key to unlocking its prostate cancer-fighting potential, according to a new article. The protective effect of tomato products against prostate cancer has been suggested in many studies, but researchers remain uncertain about the exact mechanisms.

An early age at onset of drinking is a strong predictor of subsequent alcohol dependence. New findings indicate that an early AOD among women born after 1944 may account for their increased rates of lifetime AD. An earlier AOD may be connected to decreased minimum legal drinking age laws.

The gene that allows fireflies to flash is helping researchers track the effectiveness of anti-cancer drugs over time. The technique requires a substrate called luciferin to be added to the bloodstream, which carries it to cells throughout the body. When luciferin reaches cells that have been altered to carry the firefly gene, those cells emit light.

The "Freshman 15," the notion that students gain 15 pounds during their first year of college, may overstate students' actual weight gain, according to new research. In a sample of 116 first-year female students, the average weight gain was 5.29 pounds.

Disabling a protein frequently found in melanoma tumors may make the cancer more vulnerable to chemotherapy, according to a pilot study led by researchers in the Duke Comprehensive Cancer Center. Melanoma often affects people on their extremities, with a common scenario being a mole that appears on the foot and then spreads up the leg.

Contrary to popular notions about what is normal or healthy, new research has found that it is okay not to express one's thoughts and feelings after experiencing a collective trauma, such as a school shooting or terrorist attack.

A naturally occurring molecule made by symbiotic gut bacteria may offer a new type of treatment for inflammatory bowel disease, according to scientists at the California Institute of Technology. The 100 trillion bacteria occupying the human gut have evolved along with the human digestive and immune systems for millions of years.

While Alcoholics Anonymous has existed for more than 70 years, and is the most commonly sought source of help for alcohol-related problems in the United States, there is little "hard scientific evidence" showing that AA and Narcotics Anonymous can improve substance-use outcomes. This study examined how helpful AA and NA may be for adolescents, finding long-term benefits even though many youth discontinue attendance after time.

Researchers have discovered that the effect of a protein deficiency, which is the basis of the neuromuscular disease spinal muscular atrophy, is not restricted to motor nerve cells, suggesting that SMA is a more general disorder. This new insight will allow for better understanding of how this complex disease arises.

The transmembrane MAEBL is critical for completing the life cycle of malaria parasites in mosquitoes, allowing the insects to transmit the potentially deadly infection to humans, researchers have shown.
