You might say the benefit of staying alive is an actual no-brainer: even brainless lifeforms do their best not to die. For the most part, anyway. When they’re under stress, single-celled organisms may opt to cut up their DNA and neatly implode. A new study hints that by committing suicide in this way, an organism […]The post Suicidal Algae Help Their Relatives and Harm Their Rivals appeared first on Inkfish.

Michele MarksteinUsing a new approach to systematically test chemotherapy drugs in an unusual animal model, a research team led by University of Massachusetts Amherst molecular biologist Michele Markstein, with Norbert Perrimon at Harvard Medical School, report that several have a serious side effect: Inducing hyper proliferation in stem cells that could lead to tumor recurrence.Markstein says, “We discovered that several chemotherapeutics that stop fast growing tumors have the opposite

A new study by Berkeley Lab researchers at the Joint Center for Artificial Photosynthesis (JCAP) shows that nearly 90-percent of the electrons generated by a hybrid photocathode material designed to store solar energy in hydrogen are being stored in the target hydrogen molecules. Read more »

The groundbreaking findings from the Children’s Medical Center Research Institute at UT Southwestern (CRI) also demonstrate that the precise amount of protein produced by blood-forming
