A machine learning algorithm that predicts suicide attempt recently underwent a prospective trial at the institution where it was developed, Vanderbilt University Medical Center. Over the 11 consecutive months concluding in April 2020, predictions ran silently in the background as adult patients were seen at VUMC. The algorithm, dubbed the Vanderbilt Suicide Attempt and Ideation […]

Study shows artificial intelligence can detect language problems tied to liver failure
Natural language processing, the technology that lets computers read, decipher, understand and make sense of human language, is the driving force behind internet search engines, email filters, digital assistants such as Amazon’s Alexa and Apple’s Siri, and language-to-language translation apps. Now, Johns Hopkins Medicine researchers say they have given this technology a new job as […]
how neurons in the mouse neocortex form billions of synaptic connections
The structure of synaptic connections between neurons shapes their activity and function. Measuring a comprehensive snapshot of this so-called connectome has so far only been accomplished within tiny volumes, smaller than the head of a pin. For larger volumes, the long-range connectivity, formed by bundles of extremely thin but long fibers, has only been studied […]
Finding a cause of neurodevelopmental disorders: Scientists uncover a mechanism linking a protein mutation with abnormal nervous system development
Neurodevelopmental disorders arising from rare genetic mutations can cause atypical cognitive function, intellectual disability, and developmental delays, yet it is unclear why and how this happens. Scientists suspected a mutation in a complex of proteins could be the culprit for a group of rare genetic disorders and, now, Salk Institute researchers have identified the molecular […]
New insights on overdose rates, county segregation, and socioeconomics
A new study led by George Mason University’s College of Health and Human Services found new insights into the link between county socioeconomics and segregation on drug overdose deaths. The study found that socioeconomic factors and segregated counties may affect the rate of drug overdose deaths independently and differently among racial and ethnic groups. This […]
Electronic chip mimics the brain to make memories in a flash: Engineers have mimicked the human brain with an electronic chip that uses light to create and modify memories
Researchers from RMIT University drew inspiration from an emerging tool in biotechnology — optogenetics — to develop a device that replicates the way the brain stores and loses information. Optogenetics allows scientists to delve into the body’s electrical system with incredible precision, using light to manipulate neurons so that they can be turned on or […]
Head injury effects halted by xenon gas, finds first ever life-long study in mice
TBI is the leading cause of death and disability in people under 45 in developed countries. The primary injury, caused by the initial force from a fall or car accident for example, is followed by a secondary injury which develops in the minutes, hours and days afterwards. This secondary injury is largely responsible for the […]
People in higher social class have an exaggerated belief that they are better than others: Overconfidence can be misinterpreted by others as greater competence, perpetuating social hierarchies, study says
People who see themselves as being in a higher social class may tend to have an exaggerated belief that they are more adept than their equally capable lower-class counterparts, and that overconfidence can often be misinterpreted by others as greater competence in important situations, such as job interviews, according to research published by the American […]
Regular crosswords and number puzzles linked to sharper brain in later life
Older adults who regularly take part in word and number puzzles have sharper brains, according to the largest online study to date. The more regularly adults aged 50 and over played puzzles such as crosswords and Sudoku, the better their brain function, according to research in more than 19,000 participants, led by the University of […]
Combat personnel with brain injuries pinpoints abnormal brain waves: Finding could help target brain-stimulation therapies
A new study funded by the Department of Veterans Affairs (VA) and the Navy finds that veterans and service members with a history of combat-related mild traumatic brain injury — compared with those in a control group — have much higher levels of abnormally fast brain waves in a region that plays a key role […]
