Effects of High-risk Parkinson’s Mutation Are Reversible

October 15, 2014 3:08 pm | News | Comments

Researchers have found vital new evidence on how to target and reverse the effects caused by one of the most common genetic causes of Parkinson’s.                             

Early Detection Window When Pancreatic Cancer is in the Family

October 15, 2014 2:59 pm | News | Comments

Pancreatic cancer likely takes between 10 and 20 years to develop, providing the potential for a very “broad window” of intervention if detected early, which may be possible for people who inherit a predisposition, say researchers.     

Gene Links Rare Infections with Predisposition to Autoimmune Disease

October 13, 2014 1:47 pm | News | Comments

Scientists discovered an immune protein with paradoxical roles: It both aids and tamps down aspects of an immune system response, according to new research.                           

Gene Therapy for ‘Bubble Boy’ Disease Appears Effective, Safe

October 9, 2014 11:49 am | News | Comments

A new form of gene therapy for boys with X-linked severe combined immunodeficiency syndrome (SCID-X1), a life-threatening condition also known as “bubble boy” disease, appears to be both effective and safe, according to new research.     

Coffee-drinking Genes Identified

October 7, 2014 4:35 am | by Malcolm Ritter - AP Science Writer - Associated Press | News | Comments

How much coffee do you drink every day? One cup in the morning? Or do you gulp it all day? Scientists have long known that your DNA influences how much java you consume. Now a huge study has identified some genes that may play a role.

A New Way to Extract Bone-making Cells from Fat Tissue

October 6, 2014 12:20 pm | News | Comments

By sorting human fat tissue cells by their expression of a certain gene, scientists were able to retrieve a high yield of cells that showed an especially strong propensity to make bone tissue.                 

First Pictures of BRCA2 Protein Show How it Repairs DNA

October 6, 2014 12:00 pm | News | Comments

Scientists have taken pictures of the BRCA2 protein for the first time, showing how it works to repair damaged DNA. Mutations in the gene that encodes BRCA2 are well known for raising the risk of breast cancer and other cancers.
