Should we tax robots?

What if the U.S. placed a tax on robots? The concept has been publicly discussed by policy analysts, scholars, and Bill Gates (who favors the notion).

Simulations show how bridges are damaged during earthquakes, and how we can prevent it

Researchers from Tokyo Metropolitan University have carried out a detailed simulation showing how a common type of bridge fails during large-scale earthquakes. They modeled I-shaped girder bridges, looking at the step-by-step mechanism by which they yield and deform under lateral forces, starting at the ends. Reinforcing ribs were shown to be effective against lateral forces and improve load-bearing capacity. Their work points bridge engineers to rational design strategies to make more resilient infrastructures. from Tech Xplore - electronic gadgets, technology advances and research news https://ift.tt/A5YLqop

Deep-learning model extracts important data from health records to assist with personalized medicine

Electronic health records (EHRs) need a new public relations manager. Ten years ago, the U.S. government passed a law that required hospitals to digitize their health records with the intent of improving and streamlining care. The enormous amount of information in these now-digital records could be used to answer very specific questions beyond the scope of clinical trials: What's the right dose of this medication for patients with this height and weight? What about patients with a specific genomic profile? from Tech Xplore - electronic gadgets, technology advances and research news https://ift.tt/PnGYoyT
