AI Shortcuts Speed Up Science Simulations By Billions of Times

sciencehabit shares a report from Science Magazine: Modeling immensely complex natural phenomena such as how subatomic particles interact or how atmospheric haze affects climate can take thousands of hours on even the fastest supercomputers. Emulators, algorithms that quickly approximate these detailed simulations, offer a shortcut. Now, work posted online shows how artificial intelligence can produce accurate emulators that can accelerate simulations across all of science by billions of times. The new system automatically creates emulators that work better and faster than those designed and trained by hand. And they could be used to improve the models they mimic and help scientists make the most of their time at experimental facilities.

An AI Epidemiologist Sent the First Warnings of the Wuhan Virus

An anonymous reader shares a report: On January 9, the World Health Organization notified the public of a flu-like outbreak in China: a cluster of pneumonia cases had been reported in Wuhan, possibly from vendors' exposure to live animals at the Huanan Seafood Market. The US Centers for Disease Control and Prevention had gotten the word out a few days earlier, on January 6. But a Canadian health monitoring platform had beaten them both to the punch, sending word of the outbreak to its customers on December 31 . BlueDot uses an AI-driven algorithm that scours foreign-language news reports, animal and plant disease networks, and official proclamations to give its clients advance warning to avoid danger zones like Wuhan. Speed matters during an outbreak, and tight-lipped Chinese officials do not have a good track record of sharing information about diseases, air pollution, or natural disasters. But public health officials at WHO and the CDC have to rely on these very same health of...

4 Trends that are Transforming the Future of Healthcare

4 Trends that are Transforming the Future of Healthcare Yoav Vilner / AI , Health , ReadWrite From drinking one’s own urine as a cure for broken bones to blood-letting to sending electrical shocks through a person’s body as a cure for mental illness — healthcare has a somewhat jaded past. Fortunately, as technology has improved our ability to study human physiology, medical professionals have become increasingly adept at diagnosing and curing […] from ReadWrite - The Blog of Things https://ift.tt/37qWAxu via IFTTT

Dark Mode vs. Light Mode: Which Is Better?

Recently a well-respected UI consulting firm (the Nielsen Norman Group) published their analysis of academic studies on the question of whether Dark Mode or Light Mode was better for reading? Cosima Piepenbrock and her colleagues at the Institut für Experimentelle Psychologie in Düsseldorf, Germany studied two groups of adults with normal (or corrected-to-normal) vision: young adults (18 to 33 years old) and older adults (60 to 85 years old). None of the participants suffered from any eye diseases (e.g., cataract)... Their results showed that light mode won across all dimensions : irrespective of age, the positive contrast polarity was better for both visual-acuity tasks and for proofreading tasks... Another study, published in the journal Human Factors by the same research group, looked at how text size interacts with contrast polarity in a proofreading task. It found that the positive-polarity advantage increased linearly as the font size was decreased: namely, the smaller the fon...
