'Before it released the A.I. chatbot ChatGPT last year, the San Francisco start-up OpenAI added digital guardrails meant to prevent its system from doing things like generating hate speech and disinformation. Google did something similar with its Bard chatbot.
Now a paper from researchers at Princeton, Virginia Tech, Stanford and IBM says those guardrails aren’t as sturdy as A.I. developers seem to believe.'

'Dr. Marc Sala, co-director of the Northwestern Medicine Comprehensive Covid-19 Center, said fatigue has become the dominant complaint from his patients. That could be because Covid symptoms are becoming milder overall — he no longer regularly sees patients with severe respiratory damage, and so fatigue has come to the forefront, he said. It’s also possible that fatigue could be a more common symptom with the newer variants, he said.'

"Cochrane ignored this epidemiological evidence because it didn't meet its rigid standard. I have called this approach “methodological fetishism,” when scientists fixate on a preferred methodology and dismiss studies that don't follow it. Sadly, it's not unique to Cochrane. By dogmatically insisting on a particular definition of rigor, scientists in the past have landed on wrong answers more than once."

"The European Commission is proposing a “voluntary solidarity mechanism” requested by France and Germany and an early warning system flagging when drugs become scarce, according to draft proposals seen by the Financial Times.

'CONICET, founded in 1958, has ranked as the top scientific institution in Latin America for the past five years. Its 300 research institutes employ almost 12,000 full-time researchers in all scientific disciplines.

"Retractions, which can happen for a variety of reasons, including falsification of data, plagiarism, bad methodology, or other errors, aren’t necessarily a modern phenomenon: As Oransky wrote for Nature last year, the oldest retraction in their database is from 1756, a critique of Benjamin Franklin’s research on electricity."

'Le Carré’s interview was filmed in 2019. It would be his last. He died in December 2020. And while the circumstances were sudden — a fall in his home — the writer had been 88 when sitting down with Morris. It is not an age when one is unaware that time is finite. Now, The Pigeon Tunnel shares with The Fog of War (after which Robert McNamara died in 2009) a sense of legacy.

“You make me sound like the Grim Reaper,” Morris says. Not quite, I say. But the Grim Reaper’s documentary maker? He pauses. I worry I’ve offended him. “No, I like it!”'
