Artificial intelligence (AI) tools have achieved promising results on numerous tasks and could soon assist professionals in various settings. In recent years, computer scientists have been exploring the potential of these tools for detecting signs of different physical and psychiatric conditions.

Depression is one of the most widespread psychiatric disorders, affecting approximately 9.5% of American adults every year. Tools that can automatically detect signs of depression might help to reduce suicide rates, as they would allow doctors to promptly identify people in need of psychological support.

Researchers at Jinhua Advanced Research Institute and Harbin University of Science and Technology have recently developed a deep learning algorithm that could detect depression from a person’s speech. This model, introduced in a paper published in Mobile Networks and Applications, was trained to recognize emotions in human speech by analyzing different relevant features.

During a research trial, the results of which are published in the journal Biology, healthy volunteers were given a functional MRI (fMRI) scan immediately after bathing in cold water. These scans revealed changes in the connectivity between the parts of the brain that process emotions.

For the first time, a team of researchers has observed changes in how different parts of the brain interact with each other after a person’s body is immersed in cold water. The findings explain why people often feel more upbeat and alert after swimming outside or taking cold baths.

An excellent overview of the story of how the U.S. responded to the COVID-19 pandemic along with suggestions for ways to continue making strides in combatting SARS-CoV-2 as well as how we may prepare for future emerging pathogens. The article provides an interesting case study on mechanisms of large-scale human organization, examines ways that we have succeeded in managing so many moving pieces, and explores ways that we could do better in the future. #nih #health #medicine #government #biotechnology

Investment, collaboration, and coordination have been key.

Chinese geneticist He Jiankui rocked the scientific world with his gene-edited baby experiments back in 2018, a highly controversial use of the technology that ended up sending him to a three-year stint in prison for illegal medical practices.

Now, just under a year after being released, He has some regrets about rushing into the experiments.

“I did it too quickly,” He told the South China Morning Post in a new interview.

New work shows that histones, long treated as boring spools for DNA, sit at the center of the origin story of eukaryotes and continue to play important roles in evolution and disease.
