Skin Cancer Linked to Reduced Alzheimer's Risk
May 15, 2013 5:01 pm | by Einstein | News | CommentsPeople who have non-melanoma skin cancer may be less likely to develop Alzheimer's disease, according to new research. The study showed that individuals with skin cancer were nearly 80 percent less likely to develop Alzheimer's disease compared with people who did not have skin cancer. No such association was found with other types of dementia, such as vascular dementia.

May 14, 2013 11:44 am | News | CommentsA soon-to-be-tested class of drug inhibitors were predicted to help a limited number of patients with B-cell lymphomas with mutations affecting the EZH2 protein. However, a research team now reports that these agents may, in fact, help a much broader cross section of lymphoma patients.
Gel Implant Restores Paralyzed Nerves
May 14, 2013 11:33 am | News | CommentsA team of researchers has invented a method for repairing damaged peripheral nerves. Through a biodegradable implant in combination with a newly-developed Guiding Regeneration Gel (GRG) that increases nerve growth and healing, the functionality of a torn or damaged nerve could ultimately be restored.
Protein Triggers Cell Death
May 14, 2013 11:12 am | News | CommentsWhen cells suffer too much DNA damage, they are usually forced to undergo programmed cell death, or apoptosis. However, cancer cells often ignore these signals, flourishing even after chemotherapy drugs have ravaged their DNA. A new finding may offer a way to overcome that resistance.
India to Offer $1 Rotavirus Vaccine
May 14, 2013 7:43 am | by The Associated Press | News | CommentsThe Indian government announced the development of a new low-cost vaccine proven effective against a diarrhea-causing virus that is one of the leading causes of childhood deaths across the developing world. The Indian manufacturer of the new rotavirus vaccine pledged to sell it for $1 a dose, a significant discount from the cost of the current vaccines on the market.
New Genetic Risk Factors for Testicular Cancer Found
May 13, 2013 1:10 pm | News | CommentsA new, first-of-its-kind meta-analysis looking at the genomes of more than 13,000 men identified four new genetic variants associated with an increased risk of testicular cancer, the most commonly diagnosed type in young men today. The discovery of these genetic variations could ultimately help researchers better understand which men are at high risk and allow for early detection or prevention of the disease.
Potential Flu Pandemic Lurks in Birds, Pigs
May 13, 2013 1:01 pm | News | CommentsIn the summer of 1968, a new strain of influenza appeared in Hong Kong. This strain, known as H3N2, spread around the globe and eventually killed an estimated 1 million people. A new study from MIT reveals that there are many strains of H3N2 circulating in birds and pigs that are genetically similar to the 1968 strain and have the potential to generate a pandemic if they leap to humans.
Spontaneous Mutations Crucial in Congenital Heart Disease
May 13, 2013 12:48 pm | News | CommentsEvery year, thousands of babies are born with severely malformed hearts, disorders known collectively as congenital heart disease. Many of these defects can be repaired though surgery, but researchers don’t understand what causes them or how to prevent them. New research shows that about 10 percent of these defects are caused by genetic mutations that are absent in the parents of affected children.
