Key to resilient energy-efficient AI/machine learning may reside in human brain

Posted: 01 Nov 2021 07:48 AM PDT

A clearer understanding of how a type of brain cell known as astrocytes function and can be emulated in the physics of hardware devices, may result in artificial intelligence (AI) and machine learning that autonomously self-repairs and consumes much less energy than the technologies currently do, according to researchers.

SARS-CoV-2 virus can infect the inner ear, study finds

Posted: 29 Oct 2021 04:49 AM PDT

The SARS-CoV-2 virus can infect cells of the inner ear, including hair cells, which are critical for both hearing and balance, a new study suggests. Researchers also found that the pattern of infection seen in human ear tissue is consistent with the symptoms seen in a study of 10 COVID-19 patients who reported a variety of ear-related symptoms.

In women who have experienced trauma, post-traumatic stress disorder symptoms may vary over the course of the menstrual cycle, with more symptoms during the first few days of the cycle when the hormone estradiol is low, and fewer symptoms close to ovulation, when estradiol is high, new research finds.

Death rate from Parkinson's rising in U.S., study finds

Posted: 27 Oct 2021 06:19 PM PDT

A new study shows that in the last two decades the death rate from Parkinson's disease has risen about 63 percent in the United States. The study also found that the death rate was twice as high in men as in women, and there was a higher death rate in white people than other racial/ethnic groups.
