A novel wearable magnetic metamaterial could help make MRI imaging faster, cheaper, and crisper.

While the word “mutation” may conjure up alarming notions, a mutation in brain immune cells serves a positive role in protecting people against Alzheimer’s disease. Now University of California, Irvine biologists have discovered the mechanisms behind this crucial process.

People cannot distinguish between a face generated by Artificial Intelligence – using StyleGAN2- and a real face say researchers, who are calling for safeguards to prevent “deep fakes”.

Minor everyday rises in blood pressure due to short-term stressors can be linked to a brain area that controls conscious and learned motor skills. This discovery, presented by researchers, paves the way for a chance to influence the rises in blood pressure and, in the long run, prevent hypertension.

MRI scans of children aged 9 to 10 years with ADHD showed few differences in structural brain measurements compared to their unaffected peers, according to a new study.

A recent study has shown that the brain has neurons that fire specifically during certain mathematical operations. The findings indicate that some of the neurons detected are active exclusively during additions, while others are active during subtractions. They do not care whether the calculation instruction is written down as a word or a symbol.

New research has shown that a bacterium commonly present in the nose can sneak into the brain and set off a cascade of events that may lead to Alzheimer’s disease.

A research team has discovered that communication between two key memory regions in the brain determines how what we experience becomes part of what we remember, and as these regions mature, the precise ways by which they interact make us better at forming lasting memories.

Finally this week, digital twins are already used in manufacturing, industry, and aerospace. Now a European project called Neurotwin wants to make virtual copies of brains.
