Many medications affect more than one target in the body – some drug designers are embracing the ‘side effects’ that had been seen as a drawback

Many approved drugs work on the body in ways that researchers still aren’t entirely clear about. Seeing this as an opportunity instead of a flaw may lead to better treatments for complex conditions.

NASA’s head warned that China may try to claim the Moon – two space scholars explain why that’s unlikely to happen

A comment by Bill Nelson, the NASA administrator, sparked a strong public response from the Chinese government. But due to legal and practical reasons, no country could take over the Moon anytime soon.
Social media is flush with advice urging non-menstruating people to use period tracking apps in order to trip up the apps’ algorithms. Westend61 via Getty Images

No, submitting junk data to period tracking apps won’t protect reproductive privacy

It would take huge numbers of people submitting bad data to affect the algorithms behind period tracking apps, but even then it would be more harmful than helpful.

Brain stimulation can rewire and heal damaged neural connections, but it isn’t clear how – research suggests personalization may be key to more effective therapies

Existing brain connections may influence the effectiveness of neurostimulation. Tailoring treatments to each individual brain could expand the number of conditions brain stimulation can treat.

People vary a lot in how well they recognize, match or categorize the things they see – researchers attribute this skill to an ability they call ‘o’

To achieve perceptual expertise, you may need more than smarts and hard work. Research suggests there’s a general ability that may help you succeed in jobs that depend on perceptual decisions.

Google’s powerful AI spotlights a human cognitive glitch: Mistaking fluent speech for fluent thought

Fluent expression is not always evidence of a mind at work, but the human brain is primed to believe so. A pair of cognitive linguistics experts explain why language is not a good test of sentience.
