Oct 12, 2026By Farms.com Researchers discover cattle pregnancies can succeed without a protein long considered essential For many years, scientists believed that a protein known as interferon tau (IFNT) was essential for successful pregnancy in cattle. This protein is produced by the developing embryo and was thought to send a crucial signal to the mother, helping maintain the pregnancy. However, new research from Ludwig Maximilian University (LMU) Munich has challenged this long-standing scientific belief. The study, recently published in Nature Communications, found that cattle embryos can establish and maintain pregnancies even without producing interferon tau. The discovery could change how scientists understand reproduction in cattle and may lead to new strategies to improve fertility in livestock. The research team, led by Dr.

Milky Way’s first microblazar candidate sits 12,000 light-years away, offering a rare ground-level lab for studying relativistic jetsA black hole 12,000 light-years away is firing a jet of plasma almost directly toward Earth. At that distance, no known or expected danger to Earth has been identified by the researchers or the institutions involved. What astronomers have actually found is rarer and more interesting than a threat. Researchers have identified IRAS 18293-0941 as a compelling candidate for the Milky Way’s first microblazar, a class of object that gives astrophysicists a close-up laboratory for studying some of the most violent physics in the galaxy. What Astronomers FoundThe discovery centers on a binary system whose black hole expels plasma jets at close to three-quarters the speed of light, pointed almost directly toward Earth. The system pairs a hot, massive star with a black hole that completes a full orbit roughly every 11.38 days. Material drawn from the companion star feeds the black hole, and some of that matter gets expelled outward as opposing jets traveling at approximately three-quarters the speed of light. Terminology matters here.
