Researchers at the University of Michigan Kellogg Eye Center have developed a new nanoparticle that uses a tumor cell’s protective mechanism against itself — short-circuiting tumor cell metabolism and killing tumor cells.

WHO has launched a global Strategic Response Framework and Joint Operations Plan to guide the international response to the spread of Zika virus infection and the neonatal malformations and neurological conditions associated with it.

Since 2010 scientists have known that people of Eurasian origin have inherited anywhere from 1 to 4 percent of their DNA from Neanderthals.

It may be possible to increase the neuron reserve of the hippocampus — and thus improve preconditions for learning — by promoting neurogenesis via sustained aerobic exercise such as running

The quest to bring immunotherapy into widespread clinical use against cancer and infectious diseases has made great strides in recent years. For example, clinical trials of adoptive T cell therapy are yielding highly promising results. The latest progress is being reported on February 14 at the Annual Meeting of the American Association for the Advancement of Science (AAAS 2016) by three international leaders in the field: Prof. Dirk Busch of the Technical University of Munich (TUM), Prof. Chiara Bonini of the San Raffaele Scientific Institute, and Prof. Stanley Riddell of the Fred Hutchinson Cancer Research Center and the University of Washington.

TAU, Harvard, Technion team suggests a routine blood test can reveal Alzheimer's risk and IQ measurements

A new imaging technique has allowed researchers at North Carolina State University, the University of North Carolina at Chapel Hill, and the University of Pittsburgh to see how DNA loops around a protein that aids in the formation of a special structure in telomeres. The work provides new insights into the structure of telomeres and how they are maintained.

Bethesda, Md., Fri., Feb. 5, 2016 — National Institutes of Health researchers have identified a striking signature in tumor DNA that occurs in five different types of cancer. They also found evidence that this methylation signature may be present in many more types of cancer. The specific signature results from a chemical modification of DNA called methylation, which can control the expression of genes like a dimmer on a light switch. Higher amounts of DNA methylation (hypermethylation), like that found by the researchers in some tumor DNA, decreases a gene’s activity.
