Autopsies usually point to a cause of death but now a study of brain tissue collected from people who committed suicide may explain an underlying cause of major depression and suicide. The…

"Human embryonic stem cells promise unrivalled opportunities. However, they are difficult, time-consuming and expensive to grow in the lab", says Dr. Chris Denning of Institute of Genetics, who is…

Stem cells are generally assigned to one of two categories: embryonic or adult. Some researchers say that may be an oversimplification and a new University of Michigan study states that stem cells in…

Scientists from two European-funded groups - EuroStemCell (European Consortium for Stem Cell Research) and ESTOOLS - are working together to call for a relaxation of current laws, particularly in…

6% of the patient population in Melbourne carries a genetic abnormality implicated in thalassemia. As well as causing blood disorders and severe mental retardation, boys with ATRX mutations have…

Carnegie Mellon University scientists have made an important discovery that aids the understanding of why HIV enters immune cells with ease. The researchers found that after HIV docks onto a host…

Monkey viruses related to HIV may have swept across Africa more recently than previously thought, according to new research from The University of Arizona in Tucson. A new family tree for African…

Researchers from MIT have uncovered a molecular mechanism that governs the formation of fears stemming from traumatic events. The work could lead to the first drug to treat the millions of adults who…

To protect us from disease our immune system employs macrophages, cells that roam our body in search of disease-causing bacteria. With the help of long tentacle-like protrusions, macrophages can…

A team of researchers at Umeå University in Sweden have discovered a unique mechanism by which the same signal molecule determines the formation of the both the lens of the eye and the olfactory…
