Speaking to Israeli television, reserve soldier Aviad Shapira said he found Billie among the rubble and called out to her. “I said ‘shalom’ and she jumped on me,” he said.He had a feeling that she didn’t belong in Gaza and that there was a story behind her, Shapira said. He brought the dog to a veterinarian and found the family’s contact information on a chip inside the animal.

Stroking Billie on her lap, Dancyg says it will take time to see how the odyssey has affected her. Billie appears happy to be home, but she seems disoriented and has lost weight, Dancyg said.Rachel Dancyg holds her dog, Billie, on Wednesday, April 16, 2025.

While Israeli media happily reported Billie’s return, the Nir Oz community reminded people not to forget what the family went through. In a Facebook post, the kibbutz called the reunion a “little light in a lot of sorrow.”The body of Dancyg’s ex-husband, Alex, 76, was recovered by the army and returned in August. The body of her brother

68, was returned earlier this year as part of a ceasefire.

For Dancyg, Billie’s return gives her some sense of closure. Yet she said it is bittersweet knowing there are hostages still in Gaza.A worker at United Therapeutics’ designated pathogen-free facility in Christiansburg, Va., on May 29, 2024 retrives a UV sterilized item from behind a protected barrier within the facility.

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.
