Brain specialists at The Neuroscience Institute at University Hospital and the University of Cincinnati have taken a significant step forward in their quest to treat difficult tumors while preserving areas of the brain that are responsible for speech and movement. The Cincinnati specialists are among the first in the country to use new technology that integrates functional MRI (fMRI) data into high-tech surgical navigation systems.

University of Newcastle researcher Kathryn Skelding, funded by the National Breast Cancer Foundation and Viralytics Ltd, has been working on a new treatment which only affects cancer cells – this would be an improvement on conventional chemotherapy and radiation treatment, which also impact on normal body cells.

A Hortle's Whipray -- only found in West Papua. At least 20 new species have been discovered in the first comprehensive survey of Indonesia's sharks and rays since the 1850s.

Drinking a little alcohol every day, especially wine, may be associated with an increase in life expectancy. That’s the conclusion of Dutch researchers who reported the findings of their study today at the American Heart Association’s 47th Annual Conference on Cardiovascular Disease Epidemiology and Prevention.

A Johns Hopkins study has proven false established medical practice that an antiretroviral drug widely used to treat hepatitis B liver infections was safe to use on its own in patients co-infected with HIV. Their findings demonstrate that treatment with entecavir leads to cross-resistance to other antiviral drugs used to treat the AIDS virus.

Scanning electron microscope image of A. baumannii, with maps of its genome (outer circle) and alien island sequences (inner circle – red). Researchers at Yale have identified multiple pathogenic "alien islands" in the genome of the A. baumannii, bacteria that has been responsible for new and highly drug-resistant infections in combat troops in the Middle East, according to a report in the March 1 issue of Genes and Development.

Researchers at Mount Sinai School of Medicine have just developed an advanced imaging technique to capture the movement of the microdomains of leukocytes or white blood cells. Microdomains are restricted areas on the surface of the cells in which receptors and signaling molecules accumulate during cell activation. Using digital multi-channel videomicroscopy, researchers were able to view white blood cell subsets and their forming microdomains in the vascular system in real time. In the upcoming March issue of Nature Methods, the new research displays the migration and inner workings of white blood cells in the small veins and bone marrow of mice.

MIT researchers have developed a technique to encourage the survival and growth of adult stem cells, a step that could help realize the therapeutic potential of such cells.

Deep red tomatoes get their rich color from lycopene, a disease-fighting antioxidant. A new study, however, suggests that a special variety of orange-colored tomatoes provide a different form of lycopene, one that our bodies may more readily use.

New information about a link between the growth of blood vessels critical to the spread of cancer and the copper in our bodies has been discovered by researchers from the U.S. Department of Energy's Argonne National Laboratory and the University of Chicago, using a beamline at the Advanced Photon Source.

University of Delaware researchers have developed an inexpensive, nonchlorine-based technology that can remove harmful microorganisms, including viruses, from drinking water.
