Scientists have discovered a gynandromorphic (two-sexed) bird in a Pennsylvania nature reserve.
The bird displays an even split down the middle between male and female feather coloring, leaving researchers to label it a “unicorn.”
The bird is likely a product of a genetic anomaly, but it’s perfectly healthy.
Every once in a while, a genetic anomaly will occur in the animal world that blows scientists’ minds. Take, for example, the exotic bird in the image above. It’s “gynandromorphic,” which means a specimen containing both female and male characteristics that can sometimes be seen in physical traits on the body.
Meet the rose-breasted grosbeak (Pheucticus ludovicianus), which displays an even split down the middle between male and female feather coloring. The bird’s right side shows red plumage (male), while and its left shows golden yellow feathers (female), according to scientists from the Carnegie Museum of Natural
(Reuters) — The U.S. Supreme Court appeared divided on Wednesday as it considered whether to protect Alphabet’s Google from a long-running lawsuit by Oracle accusing it of infringing Oracle copyrights to build the Android operating system that runs most of the world’s smartphones.
The shorthanded court, down one justice following last month’s death of Ruth Bader Ginsburg, heard oral arguments in Google’s appeal of a lower court ruling reviving the lawsuit in which Oracle has sought at least $8 billion in damages.
Some of the eight justices expressed concern that Google simply copied Oracle’s software code instead of innovating and creating its own for mobile devices. Others emphasized that siding with Oracle could give software developers too much power with potentially harmful effects on the technology industry.
A jury cleared Google in 2016, but the U.S. Court of Appeals for the Federal Circuit overturned that decision in 2018,
While dinosaurs ruled the land in the Mesozoic, the oceans were filled by predators such as crocodiles and giant lizards, but also entirely extinct groups such as ichthyosaurs and plesiosaurs.
Now for the first time, researchers at the University of Bristol have modelled the changing ecologies of these great sea dragons.
Mesozoic oceans were unique in hosting diverse groups of fossil reptiles, many of them over 10 metres long.
These toothy monsters fed on a variety of fishes, molluscs, and even on each other. Yet most had disappeared by the end of the Cretaceous, 66 million years ago, when the dinosaurs also died out. There are still some marine crocodiles, snakes and turtles today, but sharks, seals, and whales took over these ecological roles.
In a new study, completed when she was studying for the MSc in Palaeobiology at the University of Bristol’s School of Earth Sciences, Jane Reeves, now
