Radio-resistance in bacteria first evolves through the adaptation of DNA repair mechanisms, however as evolution continues more mutations accumulate, and more cellular metabolic processes are affected. It is not yet clear which panel of mutations provides high-level resistance. The study shows that acquisition of radio-resistance via evolution is possible independent of other mechanisms like extreme dryness resistance (desiccation).

In a new University of California, Irvine-led study, researchers have discovered how regulatory T cells (Treg) are instrumental in limiting the damage caused to the spinal cord in diseases like multiple sclerosis (MS).

Artificial intelligence can speed the development of 3D-printed bioscaffolds that help injuries heal, according to researchers at Rice University.

Based on highly sensitive recordings of neuron activity in the noses of mice, researchers from Kyushu University have found that olfactory sensory neurons can exhibit suppression or enhancement of response when odors are mixed, overturning a long-standing view that the response is a simple sum with more complex processing only happening at later stages.

Why is sleep so vital to our health? A UCLA-led team of scientists has answered this question and shown for the first time that a dramatic change in the purpose of sleep occurs at the age of about 2-and-a-half.
