'Sex' between viruses can create new influenza pandemic

A new University of Maryland-led study finds that 'sex' between the virus responsible for the 2009 flu pandemic (H1N1) and a common type of avian flu virus (H9N2) can produce offspring -- new combined flu viruses -- with the potential for creating a new influenza pandemic.

Scientists discover new mechanism of drug resistance in hospital microbes

Hospitals struggle to prevent the infections that complicate treatment for cancer, joint replacement, heart surgery and other conditions. Hospital-acquired infections are often resistant to multiple antibiotics, leading to approximately 100,000 deaths and more than $30 billion in additional health care costs yearly.

Scientists link human gene to risk of developing Mild Cognitive Impairment

Connecting a human gene to the risk of developing the Alzheimer's precondition known as Mild Cognitive Impairment has been somewhat of a holy grail for scientists, but a team led by researchers from Cornell University has ended the quest.

Treatment with estrogen dramatically lowers rates of stomach cancer in male mice

Several types of cancer, including stomach, liver and colon, are far more common in men than in women. Some scientists have theorized that differences in lifestyle, such as diet and smoking, may account for the discrepancy, but growing evidence suggests that the differences are rooted in basic biological differences between men and women.

Multiple studies find no consensus on kava-induced hepatotoxicity in Western countries

A major new review of scientific knowledge on kava - a plant used to make dietary supplements and a trendy drink with calming effects - has left unsolved the mystery of why Pacific Island people can consume it safely, while people in the United States, Europe, and other Western cultures sometimes experience toxic effects. The article appears in ACS' journal Chemical Research in Toxicology.

Cancer studies less likely to make data available for future research

A new study finds that -- even in a field with clear standards and online databases -- the rate of public data archiving in cancer research is increasing only slowly. Furthermore, research studies in cancer and human subjects are less likely than other research studies to make their datasets available for reuse.

Researchers capitalize on 'memories' of adult-derived stem cells for treatment of diabetes

Stem cells from early embryos can be coaxed into becoming a diverse array of specialized cells to revive and repair different areas of the body. Therapies based on these stem cells have long been contemplated for the treatment of diabetes, but have been held back by medical and ethical drawbacks.

New approach for producing human-derived gelatin

Scientists are reporting development of a new approach for producing large quantities of human-derived gelatin that could become a substitute for some of the 300,000 tons of animal-based gelatin produced annually for gelatin-type desserts, marshmallows, candy and innumerable other products.

Reproductive steroids may play a role in occurrence of generalized tonic-clonic seizures in women

A recent multi-center study determined that women with generalized tonic-clonic seizures (GTCS) had a greater number of seizures during anovulatory cycles-menstrual cycles where an egg is not released-than in cycles where ovulation occurs. According to the study publishing today in Epilepsia, a journal of the International League Against Epilepsy (ILAE), reproductive steroids may play a role in GTCS occurrence.
