Scientists have tamed a virus so that it attacks and destroys cancer cells but does not harm healthy cells. They have determined how to produce replication-competent viruses with key toxicities removed, providing a new platform for development of improved cancer treatments and better vaccines for a broad range of viral diseases.

A class of drugs already approved as cancer treatments might also help to beat alcohol addiction. That’s the conclusion of a discovery in flies of a gene, dubbed “happy hour,” that has an important and previously unknown role in controlling the insects’ response to alcohol.

Using such diverse sources as old ship logs, literary texts, tax accounts, newly translated legal documents and even mounted trophies, researchers are piecing together images — some flickering, others in high definition — of fish of such sizes, abundance and distribution in ages past that they stagger modern imaginations. They are also documenting the timelines [...]
There may be a new way to spice up your weight loss routine, according to results from a new animal model study. Researchers theorized that dietary curcumin could stall the spread of fat-tissue by inhibiting new blood vessel growth, called angiogenesis, which is necessary to build fat tissue.

Nearly 20 percent of patients with recently diagnosed breast cancer had additional malignant tumors found only by MRI, according to a new study.
Results of a phase I clinical trial of a novel herb-based therapeutic called Zyflamend have demonstrated that the therapy is associated with minimal toxicity and no serious adverse events in men at high-risk for developing prostate cancer.
Scientists report an evolutionary analysis of a critical protein produced by the 2009 H1N1 influenza A virus strain.

Drinking on college campuses in the United States is a pervasive problem, leading to numerous problems. One study estimated that more than 500,000 college students suffered alcohol-related injuries in 2001. This study examined the “dose-response” effect of quantities and frequencies, finding that heavy drinkers with a sensation-seeking disposition had the greatest risk of alcohol-related injuries.

In the Japanese art of paper folding, a series of folds can make the same sheet of paper into a ballerina or baby elephant. But try unfolding the baby elephant and making it into a ballerina. It’s like trying to make a neuron from a kidney cell. Epigenetics, it turns out, isn’t much different from [...]
