Researchers have used human neural stem cells to 3D print functional brain tissue that mimics the architecture of the cerebral cortex, the brain’s outermost layer, and has the potential to provide individualized repairs to brain injuries.
-
Ongoing stress can take a sizeable toll on the body, including higher risks of obesity, graying hair, hypertension, diabetes and cardiovascular disease. And it may be just as damaging to the brain, even doubling the risk of developing dementia.

Delivering electric shocks to 1mm-long roundworms may sound rather meanspirited, but scientists have used this stimuli to uncover some curious behaviors of C. elegans that could further our understanding of human emotional mechanisms.
-
Scientists at Stanford Medicine have tested a new potential treatment for Alzheimer’s disease in mice. The therapy involves transplanting blood stem cells from healthy mice into those with the disease, which helps replace defective neural cells.
-
A new study has found that light therapy applied to mice during deep sleep increased the brain’s ability to clear away beta-amyloid protein, which may lead to a drug-free, non-invasive treatment for Alzheimer's disease.

When you take 800,000 human brain cells, wire them into a biological hybrid computer chip, and demonstrate that it can learn faster than neural networks, people have questions. We speak to Dr. Brett Kagan, Chief Scientific Officer at Cortical Labs.
-
Researchers have gained new insights into largely overlooked circular RNAs in brain cells and the crucial role they play in diseases like Alzheimer’s and Parkinson’s, opening the door to developing diagnostic tests and treatments for them.
-
Following years of controversy, including whistleblowers reporting of rushed experimental “hack jobs” that resulted in as many as 1,500 animal fatalities, Elon Musk's brain-chip implant company has begun recruiting for its landmark first human trial.
-
Two months on from it being declared safe by the FDA, aspartame is again making headlines for the wrong reasons, this time for its potential negative impact on learning and memory. In a mice study, these cognitive impairments were passed on to young.
-
Researchers have found that an intranasal drug, currently being tested as an MS treatment, reduced brain inflammation and improved cognition in mice with Alzheimer’s disease, independent of the amount of beta-amyloid plaques present.
-
Using brain imaging, researchers have found that obsessive-compulsive disorder affects particular areas of the brain involved in processing certainty during the decision-making process, providing greater insight into this enigmatic condition.
-
A study has found that targeting specific brain areas with ultrasound causes functional changes that last up to an hour. It paves the way for developing non-invasive methods of treating mental health conditions such as depression and anxiety.
