Brain Signals Turned Into Speech

Scientists have harnessed artificial intelligence to translate brain signals into speech, in a step toward brain implants that one day could let people with impaired abilities speak their minds, according to a new study.
 In findings published Wednesday in the journal Nature, a research team at the University of California, San Francisco, introduced an experimental brain decoder that combined direct recording of signals from the brains of research subjects with artificial intelligence, machine learning and a speech synthesizer.

Digital Data in Health Care Promises Much, Has Limits

Technology is reshaping health care, from pharmaceutical research to detecting opioid addiction, even though the pace of change isn't as dramatic as some had hoped a few years ago, industry leaders said at The Wall Street Journal Health Forum on Tuesday.
 Novartis AG Chief Executive Vas Narasimhan said opportunities presented by artificial intelligence are, for now, on the margin. “It's another tool in the toolbox,” he said. Doctors, insurers and drugmakers are experimenting with digital technology at a brisk pace after years of watching internet access and smartphones disrupt nearly every other economic sector.

NIH Silences Clinical Trial's Critics

The National Institutes of Health, the U.S. government's premier health research agency, is refusing to allow two of its doctors to respond to government investigators looking into the quality of a continuing clinical trial of new blood-infection treatments on thousands of patients, according to NIH documents and multiple interviews.
 The resulting tensions within the NIH have pitted the office of the agency's director, Francis Collins, against an internal NIH committee of 24 scientists, who are raising questions over the freedom researchers are afforded to critique the work of colleagues.

Crisis and suicide prevention services struggle with demand after celebrity suicides

The United States may lack the resources needed to meet increases in demand for suicide prevention services that occur after celebrity suicides, according to a recent study of crisis mental health services. The study, conducted by a team of researchers, which included scientists from the National Institute of Mental Health (NIMH), part of the National Institutes of Health, highlights the need for suicide prevention hotlines to procure additional funds, allocate existing funds more efficiently, and develop contingency plans to accommodate increases in call volumes, particularly for the first two days after a celebrity suicide. The findings appear in the journal Psychiatric Services.
