This week’s biology news brings us remarkable discoveries that push the boundaries of science. Researchers have successfully created the first bi-paternal mouse, shedding light on unisexual reproduction in mammals. In the U.S., scientists have identified a close relative of the deadly Hendra virus, raising concerns about potential zoonotic threats. Meanwhile, a new study links delayed REM sleep to early signs of Alzheimer’s, offering a potential early detection method for the disease. Let’s dive into the details!

First Mouse with Two Male Parents Reaches Adulthood
For the first time, scientists have successfully created a bi-paternal mouse—one with two male parents—that survived to adulthood. By modifying key imprinting genes, researchers overcame significant barriers that have previously prevented unisexual reproduction in mammals. While the survival rate was low, and the mice were sterile, this breakthrough could reshape the future of reproductive biology, cloning, and regenerative medicine. However, ethical and technical challenges remain before such technology could be applied to larger animals or humans.

Deadly Hendra Virus Relative Discovered in the U.S.
Scientists have identified Camp Hill virus, a newly discovered henipavirus, in shrews in Alabama. This marks the first time a virus from this deadly family has been found in North America. Henipaviruses, such as Hendra and Nipah viruses, have high fatality rates and have caused deadly outbreaks in other regions. Researchers are now investigating whether this virus poses a risk to humans and are working on potential vaccines. The discovery highlights the growing need for global virus surveillance and preparedness.
Delayed REM Sleep Could Be an Early Warning Sign of Alzheimer’s
A new study reveals that taking longer to enter REM sleep—the phase crucial for memory processing—may be an early indicator of Alzheimer’s disease. Researchers found that individuals with delayed REM sleep had higher levels of toxic amyloid and tau proteins, both linked to Alzheimer’s progression. The findings suggest that improving sleep quality might help reduce cognitive decline. Future research will explore whether medications that enhance REM sleep could slow or prevent the disease.
