Prepare for a winter covid-19 spike now, say medical experts
Tue, 14 Jul 2020 11:06:14 +0000
The news: We should prepare now for a potential new wave of coronavirus cases this winter, according to the UK’s Academy of Medical Sciences. Health-care systems tend to struggle in winter anyway because infectious diseases spread faster as we spend more time in poorly ventilated indoor spaces, and because conditions like asthma, heart attacks, and…
The US is turning away the world’s best minds—and this time, they may not come back
Tue, 14 Jul 2020 09:00:00 +0000
Editor’s note: On July 14, 2020, the Trump administration said it would reverse an Immigration and Customs Enforcement rule that would have required foreign students to leave the US if they were taking all of their classes online.

If the coronavirus is really airborne, we might be fighting it the wrong way

A new way to train AI systems could keep them safer from hackers
Fri, 10 Jul 2020 14:03:28 +0000
The context: One of the greatest unsolved flaws of deep learning is its vulnerability to so-called adversarial attacks. When added to the input of an AI system, these perturbations, seemingly random or undetectable to the human eye, can make things go completely awry. Stickers strategically placed on a stop sign, for example, can trick a…
