The fibers of the vagus nerve have many crucial roles. The vagus nerve helps regulate many physical functions including controlling heart rate and speech; it is related to the feeling of satiety after ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. Billions of nerve cells send signals coursing through our bodies, serving as conduits ...

Nerve cells are not just nerve cells. Depending on how finely we distinguish, there are several hundred to several thousand different types of nerve cell in the human brain according to the latest ...

You’ve probably heard the old canard that new brain cells simply stop forming as we become adults. But research out today is the latest to show that this isn’t really true. Scientists in Sweden led ...

Yusuf Roohani, PhD, machine learning group lead at the Arc Institute, is among a team of researchers training artificial intelligence (AI) models with transcriptome data to predict how cell gene ...

The video I am watching feels like a scene from a horror movie. At the centre of the screen is a blood-red mass – in reality, a massively magnified pancreatic tumour, vividly dyed as if to highlight ...

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 ...

In June, the Centers for Medicare & Medicaid Services (CMS) will name the participating states for the agency’s new Cell and Gene Therapy (CGT) Access Model. One state has already started ...

Scientists created a model of the human pain pathway in a dish by connecting four separate brain organoids. The feat should help them understand sensory disorders like those affecting pain perception.

For over 150 years, scientists have known that wounds alter electric fields across skin cells, says cell biologist Min Zhao of the University of California, Davis School of Medicine. But they didn’t ...
