Superoxide anions O2-, a radical oxygen, shows a bioactive function such as detoxification in the living body. On the other hand, an excess of superoxide…
An international team of scientists including the University of Leeds Liane Benning have successfully trialled techniques to search for life on Mars. Their findings – microbes deep within ice-filled volcanic tubes – reveal how to test for life on the red planet.
Dr Benning from earth and environment is the sole UK member of the AMASE team studying rocks, ice and micro-organisms on the arctic island of Svalbard in Norway, which has a geology similar to that of parts of Mars. “
Laboratory experiments at UCR demonstrate interactions between two atoms containing antimatter
What happens when two atoms, each made up of an electron and its antimatter counterpart, called the positron, collide with each other? UC Riverside physicists are able to see for the first time in the laboratory that these atoms, which are called positronium atoms and are unstable by nature, become even more unstable after the collision. The positronium atoms are seen to destroy one a
Increasing the activity of two enzymes better known for their role in oxidative stress metabolism turns normally relaxed mice into “Nervous Nellies,” according to research conducted at the Salk Institute for Biological Studies and reported in the early online edition of Nature.
Locally overexpressing either glyoxalase 1 or glutathione reductase 1 in mouse brains significantly increased anxiety in usually relaxed mice and made already jittery mice even more anxiety-ridden. Inhib
Discovery could lead to prostate-cancer-specific diagnostic test and more effective treatment
Scientists at the University of Michigan Medical School, in collaboration with researchers at Harvards Brigham and Womens Hospital, have discovered a recurring pattern of scrambled chromosomes and abnormal gene activity that occurs only in prostate cancer.
In a paper being published in the Oct. 28 issue of Science, the research team indicates that these chromosomal rea
New tool speeding the discovery of genes for common diseases
The International HapMap Consortium today published a comprehensive catalog of human genetic variation, a landmark achievement that is already accelerating the search for genes involved in common diseases, such as asthma, diabetes, cancer and heart disease.
In a paper in the Oct. 27 issue of the journal Nature, more than 200 researchers from Canada, China, Japan, Nigeria, the United Kingdom and the United
