Researchers advance understanding of schistosome reproduction

Ancient Egyptian mummies revealed that humans have been hosting parasitic flatworms called schistosomes for more than 5,000 years. Today the parasites continue to plague millions of people across the world, causing roughly ...

Critical pathway in cell cycle may lead to cancer development

A team of scientists at the Salk Institute for Biological Studies has identified why disruption of a vital pathway in cell cycle control leads to the proliferation of cancer cells. Their findings on telomeres, the stretches ...

Vicious cycle: Obesity sustained by changes in brain biochemistry

With obesity reaching epidemic levels in some parts of the world, scientists have only begun to understand why it is such a persistent condition. A study in the Journal of Biological Chemistry adds substantially to the story ...

Cell death in retina helps tune our internal clocks

(Medical Xpress)—With every sunrise and sunset, our eyes make note of the light as it waxes and wanes, a process that is critical to aligning our circadian rhythms to match the solar day so we are alert during the day and ...

Mutant parasite could stop malaria in its tracks

(Medical Xpress)—University of Nottingham Malaria experts have found a way of disabling one of the many phosphatase proteins which breathe life into the malaria parasite. The result is a mutant which is unable to complete ...

Molecular switch identified that controls key cellular process

The body has a built-in system known as autophagy, or 'self-eating,' that controls how cells live or die. Deregulation of autophagy is linked to the development of human diseases, including neural degeneration and cancer.

Demystifying the immortality of cancer cells

(Medical Xpress) -- In cancer cells, normal mechanisms governing the cellular life cycle have gone haywire. Cancer cells continue to divide indefinitely, without ever dying off, thus creating rapidly growing tumors. Swiss ...
