People who give up smoking might reduce accelerated thinning of the cortex – the brain’s outer layer which is important for thinking skills. Researchers have found that people who avoided smoking had a thicker outer layer of the brain than people who had smoked.
The first comprehensive computer model to simulate the development of blood cells could help in the development of new treatments for leukaemia and lymphoma, say researchers at the University of Cambridge and Microsoft Research. The human body produces over 2.5 million new blood cells during every second of our adult lives, but how this process is controlled remains poorly understood.
Researchers have cracked a code that governs infections by a major group of viruses including the common cold and polio. Until now, scientists had not noticed the code, which had been hidden in plain sight in the sequence of the ribonucleic acid (RNA) that makes up this type of viral genome.
