A look back at the starlet's life on what would've been her 95th birthday.

The Surprise Hiding in the DNA of Pet Fish Sarah Zhang © anisah_priyadi / getty In 1975, scientists tried spaying a few hundred female betta fish. We all know what happens to spayed cats and dogs: They become sterile. Betta fish are different. A third of the surviving bettas regenerated an ovary—which, okay, interesting enough. But the remaining two-thirds did something much, much stranger: They grew testes. They turned brighter and darker in color too—like male bettas. Th...

The Atlantic Domesticated betta fish have evolved a sex gene not found in wild fish of their species. anisah_priyadi / getty In 1975, scientists tried spaying a few hundred female betta fish.

Now, a new study provides a ray of hope for the remaining fish. Researchers have found the cod haven’t lost the genetic diversity that would be crucial for their recovery, something that often happens when species hit a so-called population “bottleneck.” The new research—the first to compare whole genomes of cod from before and after intensive fishing—reinforces the notion that more protective management will help beleaguered stocks bounce back, experts say. “It’s an excellent stu...

A Matt’s Maker Space lab is opening at Point Park University, offering School of Education students the opportunity to immerse themselves in modern teaching and learning concepts related to maker education and Science, Technology, Engineering and Math education. The lab is named for local nonprofit Matt’s Maker Space, which donated to the University to bring the vision to reality. The organization was founded by Noelle and David Conover in 2018 in memory of their son, Matt, a Mt. Leba...
