With a White House-brokered deal, vaccine giant Merck has agreed to help Johnson & Johnson boost its COVID-19 vaccine production, which is woefully behind on its manufacturing schedule.

President Joe Biden announced today that, with the new deal, the country is on track to have enough COVID-19 vaccine doses to vaccinate every adult in the country by the end of May—two months ahead of earlier plans.

“About three weeks ago, we were able to say that we’ll have enough vaccine supply for adults by the end of July,” the president said in an afternoon address. “And I’m pleased to announce today, as a consequence of the stepped-up process that I’ve ordered and just outlined, this country will have enough vaccine supply—I’ll say it again—for every adult in America by the end of May. By the end of May. That’s progress—important progress.”

Certain species show a remarkable ability to delay gratification, notably great apes, corvids, and parrots, while other species do not (such as rodents, chickens, and pigeons.) Add the cuttlefish to the former category.

Scientists administered an adapted version of the Stanford marshmallow test to cuttlefish and found the cephalopods could delay gratification—that is, wait a bit for preferred prey rather than settling for a less desirable prey. Cuttlefish also performed better in a subsequent learning test, according to a new paper published in the journal Proceedings of the Royal Society B. It's the first time such a link between self-control and intelligence has been found in a non-mammalian species.

As we've previously reported, the late Walter Mischel's landmark behavioral study involved 600 kids between the ages of four and six, all culled from Stanford University's Bing Nursery School. He would give each child a marshmallow and give them the option of eating it immediately if they chose. But if they could wait 15 minutes, they would get a second marshmallow as a reward. Then Mischel would leave the room, and a hidden video camera would tape what happened next.
