Biologists now think there is a larger spectrum than just binary female and male

About 310 million years ago in what's now Arizona, a primitive creature trundled along on all fours through towering sand dunes that spilled into the sea. Normally, this creature's tracks would have vanished like other footfalls on a beach. But in a rare case, the tracks hardened into sandstone—preserving this flash of ancient behavior.

Some 310 million years ago, a reptile-like creature with an unusual gait roamed the sandy expanses of the Grand Canyon, leaving a trail of 28 footprints that can still be seen today. As Michael Greshko reports for National Geographic, these unusually well-preserved markers represent the national park’s oldest footfalls—and, if additional analysis links the early reptile to one that left a similar set of prints in Scotland roughly 299 million years ago, the tracks may even earn the distinction of being the oldest of their kind by more than 10 million years.

We hear the term "fake news" all the time, so let's talk about it. First of all, fake new is not real news.

Freed from the binary of boy and girl, gender identity is a shifting landscape. Can science help us navigate?

On Oct. 14, the CW network debuted its transgender “Supergirl” character Dreamer/Nia Nal and the University of Nevada, Las Vegas gender and sexuality studies professor Dr. Erika Gisela Abad has given her insights into the character and its portrayal by transgender actress Nicole Maines.

Eighty-nine days before the November election, Ashenafi Hagezom is up before dawn. From his two-bedroom house in northwest Las Vegas, which he shares with roommates, it can take up to an hour to reach the Bellagio, the faux-Italian luxury hotel and casino in the heart of the Strip. He parks in the employee garage out back and passes through the air-conditioned doors just after 7 a.m., before the graveyard shift begins to trickle out and gives way to the army of guest-room attendants, prep cooks, and porters who keep the casino humming for another day.

Rogue planets are the drifters of the galaxy, wandering interstellar space alone. Now it turns out they could have company in the form of moons — and perhaps even sustain life that hitched a ride on them.

The entertainment industry has been attempting to combat piracy since the dawn of the digital age, but it turns out explicit warnings are the most effective.

That is the conclusion of a study from researchers at the University of Nevada, Las Vegas looking at the different types of anti-piracy messaging and which have the most impact with consumers.

Researchers from the University of Nevada, Las Vegas, conducted a study to find out which piracy warnings are seen as most effective by the general public.
