1 . Brilliant though it is, Project Debater has some weaknesses. It takes sentences from its library of documents and prebuilt arguments and strings them together. This can lead to the kinds of errors no human would make. Such wrinkles will no doubt be ironed out, yet they also point to a fundamental problem. As Kristian Hammond, professor of electrical engineering and computer science at Northwestern University, put it: “There’s never a stage at which the system knows what it’s talking about.”

2 . The letter explains some of the immediate actions the site team has taken to mitigate the flood damage, like bringing in water pumps and repairing brickwork. But it’s clear that these measures will not be enough.

3 . These findings are good news for life in the universe as they dispel concerns that potentially habitable planets could not form too close to very massive stars. Previously, scientists thought the intensity of ultraviolet (紫外线的) radiation produced by massive stars would interfere (干扰) with the distribution of dust and gas in planet-forming stars, possibly preventing the formation of rocky planets like Earth, for instance. The NGC 6357 group contains more than ten super bright and massive stars, suggesting most of the group’s matter is exposed to high levels of ultraviolet radiation.

4 . People have been manipulating (操纵) organisms for human benefit since at least the dawn of agriculture, genetic editing is becoming widespread, and a few artificial organisms have been manually assembled in the past few years — copying the body forms of known animals. But this research, for the first time ever, “designs completely biological machines from the ground up, “the team writes in their new study.

5 . Duchess Nina’s work during World War II was not without its risks. She frequently risked her life to save animals, often driving through perilous areas.

6 . Kariko worked in a few different research jobs before landing a junior position at the University of Pennsylvania. And for many years her career at the UPenn was fragile. She migrated from lab to lab, relying on one senior scientist after another to take her in. She never made more than $60,000 a year. She struggled to raise the funding essential for a scientific career and never had a stable position. Kariko said she endured being made fun of by university colleagues for her dogged pursuit. In 2013, she was kicked out from UPenn — forced to retire. She said in an interview that the university told her that she was unfit for her work. Yet the scientist’s commitment to her work did not falter. “When I was terminated (终止), I didn’t feel sorry for myself,” she said. “I have to focus all the energy on seeking out what’s next.”

7 . Asch found that one-third of real participants gave the same wrong answers as the confederates at least half the time. Forty percent gave some wrong answers, and only one-fourth gave correct answers in defiance of the pressure to conform to the wrong answers provided by the group.

8 . Glover and her colleagues tested their hypothesis in the lab. In their experiment, they found that bees felt confused sometimes when the petals were very iridescent and that bees had no problem finding the flowers with more nectar when the petals were not very iridescent. The team shared its new findings in the March 21 Current Biology.

9 . The call for public engagement with the unthinkable is especially germane in this moment of still-uncontrolled pandemic and economic crises in the world’s most technologically advanced nations. Not very long ago, it was also unthinkable that a virus would shut down nations and that safety nets would be proven so disastrously lacking in flexibility.

10 . Testing nonhuman memory retention (保持) is challenging; in research studies, “it’s rare that there is a gap of several years between when an animal stores the information and when it is next required to retrieve it,” says University of Oxford zoologist Dora Biro. For a recent study in the Proceedings of the Royal Society B, Biro and her colleagues compared domestic homing pigeons’ paths three or four years after the birds established routes back to their loft from a farm 8.6 kilometers away. The study built on data from a 2016 experiment in which pigeons learned routes in different social contexts during several flights — on their own or with peers that did or did not know the way.
