Alcohol Damages DNA and Increases Cancer Risk

Much previous research looking at the precise ways in which alcohol causes cancer has been done in cell cultures. But in this study, researchers have used mice to show how alcohol exposure leads to permanent genetic damage. Scientists at the MRC Laboratory of Molecular Biology, Cambridge, gave diluted alcohol, chemically known

Harnessing sperm to treat gynecological Diseases

Creating an effective way to target cancer cells with drugs is challenging on multiple fronts. For example, the drugs don't always travel deeply enough through tissues, and they can get diluted in body fluids or sidetracked and taken up by healthy organs. To get around these issues, scientists have turned

New Methods Reveal the Biomechanics of Blood Clotting

The extensive results are published in two separate studies, in the Proceedings of the National Academy of Sciences (PNAS) and in Nature Methods. "We show conclusively that, in order to activate clotting, the cell needs a targeted force of a magnitude of just a few piconewtons -- or a force about a billion times

Fighting Myocardial Infarction with Nanoparticle Tandems

In a heart attack, clots usually lead to persistent circulatory problems in parts of the heart muscle, which then cause heart muscle cells to die. Attempts have been made for some time to revitalize the damaged heart tissue with replacement cells. "However, most of the cells are pushed out of

Brain Cortex Development: Ryk Needs a Chaperone

In the study, first authors Wen-Hsuan Chang from the USC Stem Cell laboratory of Wange Lu, Si Ho Choi from the Dongnam Institute of Radiological & Medical Sciences (DIRAMS) in South Korea, and their colleagues describe how Ryk and its chaperone contribute to the development of the brain's cortex, which

Engineering Non-immune Cells to Kill Cancer Cells

But researchers have recently used T-cells engineered in the laboratory to combat tumours. Modified to include additional functions, these immune cells can hunt down and kill cancer cells. Unfortunately, however, such immune cell therapies can have significant side-effects. On top of that, the production of modified T-cells is technically challenging.
