内容摘要：Actual contamination may affect only a small amount of product, but firms recall all food produced within a certain window just to be safe. And while some of the food may be able to be “reconditioned” or treated for safety and sold again, “most of the time, it’s going to landfills,” Mirdamadi said.

Mild electric shocks fuse in the new DNA and activate embryo growth.

Ayares, a molecular geneticist who heads Revivicor and helped create the world’s first cloned pigs in 2000, says the technique is “like playing two video games at the same time,” holding the egg in place with one hand and manipulating it with the other. The company’s first modified pig, thesingle gene knockout, now is bred instead of cloned. If xenotransplantation eventually works, other pigs with the desired gene combinations would be, too.Hours later, embryos are carried to the research farm in a handheld incubator and implanted into waiting sows.

On the research farm, Tom Petty’s “Free Fallin’” was serenading a piglet barn, where music acclimates the youngsters to human voices. In air-conditioned pens, the animals grunted excited greetings until it’s obvious their visitors brought no treats. The 3-week-olds darted back to the security of mom. Next door, older siblings laid down for a nap or checked out balls and other toys.

“It is luxury for a pig,” Ayares said. “But these are very valuable animals. They’re very smart animals. I’ve watched piglets play with balls together like soccer.”Meyers noted that time commitment as well.

“By having Geno, it kind of brings a sense of stability,” Meyers said. “He knows what he’s doing. He shows up the same every day, his personality stays the same every day. I haven’t seen him have a bad day yet. So I can’t have bad days if the leader has no bad days.”NEW YORK (AP) — Tyrese Haliburton smiled widely as he envisioned the scene Sunday when the Pacers host Game 3 of the Eastern Conference finals to cap a daylong

Yet along with the Pacers’ excitement after winning the first two games against the New York Knicks at Madison Square Garden came a word of caution. A 2-0 lead guarantees nothing and things can change quickly.Look no further than last year in a series between these same teams.
