Washington, Mar 23 : In a major advance in cancer treatment, nanotechnology researchers have developed the first hollow gold nanospheres that search out and "cook" cancer cells.
The researchers say that the cancer-destroying nanospheres, smaller than the finest flecks of dust, particularly show promise as a minimally invasive future treatment for malignant melanoma, the most serious form of skin cancer.
Washington, March 23 : German scientists have developed an automated synthesizer that can enable the use of carbohydrates in revolutionary new vaccines and drugs to battle malaria, HIV, and a bevy of other diseases.
Dr. Peter H. Seeberger, principal investigator for the research, developed the device at the Swiss Federal Institute of Technology in Zurich.
He says that it can build intricate molecules in a few hours, instead of the months or years required with existing technology.
Washington, Mar 23 : A new study has found that an increase in formal schooling has led to a reduction in AIDS infections in sub-Saharan Africa.
During the early stages of the HIV pandemic in the region, the disease passed unnoticed amidst the onslaught of other infections.
But after taking a closer look at the deadly disease, scientists have found that more often males with a higher than average education were contracting the disease.
Washington, March 23 : Scientists at the University of Michigan have come up with a new method of detecting nitric oxide in exhaled breath, elevated levels of which are a telltale sign of diseases like lung cancer and tuberculosis.
The researchers say that their work may prove useful in diagnosing illness and monitoring the effects of treatment.
Washington, Mar 23 : A new type of yoghurt has been found to be effective against bacteria that cause stomach ulcers, according to a new study.
A type of bacteria called Helicobacter pylori (H. pylori) or over-use of aspirin and or other nonsteroidal antiinflammatory drugs causes most stomach ulcers.
During the study, the research team led by Dr. Hajime Hatta, a chemist at Kyoto Women''s University in Kyoto, Japan, found that H. pylori seems to rely on a protein called urease to attach to and infect the stomach lining.
London, Mar 23: Scientists in the UK have found that a type of drug designed to stunt tumour growth can actually encourage cancer if given at too low a dose.
They looked at angiogenesis inhibitors designed to block the supply of blood to tumours to prevent them from growing.
For their study, the scientists studied an experimental angiogenesis inhibitor called Cilengitide that has yet to be licensed for patients.
In this study, tests conducted on mice showed that low doses of Cilengitide actually stimulated the growth of cancers.
