How does coffee affect a sleeping brain?

Coffee can help you stay awake. But what does caffeine actually do to your brain once you’re asleep? Using AI, a team of researchers has an answer: it affects the brain’s ‘criticality’.

Electronic tattoo gauges mental strain

Researchers gave participants face tattoos that can track when their brain is working too hard. The study introduces a non-permanent wireless forehead e-tattoo that decodes brainwaves to measure mental strain without bulky headgear. This technology may…

Resetting the fight-or-flight response

The activation of Protein Kinase A (PKA) is a critical part in how the body responds to stress and starvation. Using a variety of imaging and biochemical techniques, a team of researchers has revealed how the metabolic cycle that activates PKA resets i…

Horses ‘mane’ inspiration for new generation of social robots

Interactive robots should not just be passive companions, but active partners — like therapy horses who respond to human emotion — say researchers.

Sharing of lifespan brain study data expected to light new paths

Researchers have released the full dataset from the Dallas Lifespan Brain Study, a decade-long project designed to track brain and cognitive health as people age and distinguish neurologically healthy paths from those indicating a likelihood of decline.

Scientists test real-time view of brain’s waste removal

A new device that monitors the waste-removal system of the brain may help to prevent Alzheimer s and other neurological diseases, according to a new study. In the study, participants were asleep when they wore the device: a head cap embedded with elect…

Newly identified group of nerve cells in the brain regulates bodyweight

Obesity is a global health problem that affects many people. In recent years, very promising anti-obesity drugs have been developed. Despite these successes, there are patients who do not respond to these drugs or suffer from side effects. Therefore, t…

A switchboard with precision: How the brain licenses movements

Neurons deep in the brain not only help to initiate movement — they also actively suppress it, and with astonishing precision. The findings are especially relevant for better understanding neurological disorders such as Parkinson’s disease.

Mother’s warmth in childhood influences teen health by shaping perceptions of social safety

Parental warmth and affection in early childhood can have life-long physical and mental health benefits for children, and new research points to an important underlying process: children’s sense of social safety.

Research untangles role of stress granules in neurodegenerative disease

Scientists found that stabilizing stress granules suppresses the effects of ALS-causing mutations, correcting previous models that imply stress granules promote amyloid formation.
