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).
It is well understood that mortality rates increase with age. Whether you live in Tokyo, rural Tennessee or the forests of Papua, New Guinea, the older you are, the more likely you are to succumb to any number of different ailments.
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.
Determining whether high-intensity interval training (HIIT) is an appropriate form of exercise for the average person has been hotly debated for years. But for one UBC Okanagan researcher, there's not much to debate--interval exercise, when used appropriately, can fit into people's menu of flexible exercise options.
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.
Genome Biology and Evolution's latest virtual issue highlights recent research published in the journal within the field of human genetics.
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.
Study shows that short, easy-to-apply relaxation techniques can activate the body's regenerative system for fighting stress--offering new perspective on how we can treat stress-related disease
How much time does a brain need to learn a new word? A team of Skoltech researchers and their colleagues monitored changes in brain activity associated with learning new words and found that cortical representations of the sound and meaning of these words may form in just 1 to 2 hours after exposure without any night's sleep consolidation, as earlier research suggested. This research has implications for diagnosing speech disorders and improving the efficiency of learning.
