Science Nation - Evolution in Action

submitted by: nsf
Professor Lawrence Gilbert and his team at the University of Texas at Austin have discovered a population of tropical butterflies that exemplify "evolution in action," and a rare research opportunity. Gilbert says they may be witnessing a species of butterfly splitting into two different species.

The connection between genes and colon cancer

submitted by: mdanderson

About 20% of colon cancer cases are related to a strong family history of colon cancer. Eduardo Vilar-Sanchez, M.D., Ph.D., Assistant Professor in the Department of Clinical Cancer Prevention at The University of Texas MD Anderson Cancer Center, focuses his discussion on the main types of genetic colon cancers including hereditary nonpolyposis colorectal cancer syndrome or HNPCC (also called Lynch syndrome) and familial adenomatous polyposis (FAP).

Intestinal microbiota and human health

submitted by: COMED2010
The central objective of the MetaHit project is to establish associations between the genes of the human intestinal microbiota and human health and disease. The research work is focused on two disorders of increasing importance in Europe, Inflamatory Bowel Disease (IBD) and obesity. First, we need to establish an extensive reference catalog of microbial genes and genomes present in the human intestine. The second challenge is to develop tools to determine which genes and genomes of the...

How to define human biological age

submitted by: COMED2010
Towards establishing biomarkers of human ageing “European Study to Establish Biomarkers of Human Ageing (MARK-AGE)” brings together 26 groups located in 14 European countries. The scientific background is the following: The rate of ageing in humans is not uniform, age-related changes in body function or composition that could serve as a measure of “biological” age and predict the onset of age-related diseases and/or residual lifetime are termed “biomarkers of ageing”. Within the...

Dogs help to decode human DNA

submitted by: COMED2010
Dogs are more than man’s best friends; they can help us unravelling the genetic of diseases such as cancer, epilepsy, cardiovascular troubles, diabetes etc. Living in the same environment human and dogs are suffering from the same diseases but the genetic complexity is quite lower in dogs. During 4 years 20 veterinary schools spread across Europe are working together to collect 10.000 blood samples from purebred dogs affected by similar diseases as human. The analysis of the genome of...
