A recent study published in the journal Social Sciences has found that stories about dangerous, attractive women are almost universal across different cultures. These cautionary tales suggest that men tend to fear the risks of emotional attachment and heartbreak just as much as they are drawn to physical beauty. Ultimately, this research indicates that the famous “femme fatale” character stems from human evolutionary psychology rather than simply local cultural attitudes.

Join us for a conversation about decolonizing research, rethinking education, and building institutions that actually serve the communities at their center. Chris sits down with Dr. Alyssa Crittenden, who returns to the show, this time as Vice Provost for Graduate Education and Dean of the Graduate College at UNLV.

The standard in the US is for the placenta to be treated as medical waste, but cultures across the world have had widely varied traditions, often tied to the belief that the placenta is a living relative or guardian to the child. In an analysis of 179 societies, medical anthropologists at the University of Nevada, Las Vegas, found 169 disposal methods, including burial, incineration, and intentional placement in a specific location, such as hanging in a tree.

Dr. Brian Villmoare of the University of Nevada – Las Vegas shares how his team found teeth in Ethiopia and what those teeth might mean in terms of who was around when in the evolutionary record.

The 2nd annual Missing in Nevada Day is set to run from 10 a.m. to 4 p.m. on Jan. 31 at UNLV's University Gateway Building.

A study on Ozempic’s impacts on Alzheimer’s disease didn’t have the results scientists hoped for. We talk to UNLV’s Dr. Jeffrey Cummings on the research and what’s next. Also from UNLV: a look at how a “new” species of an ancient human ancestor can help shape our view on evolution. We end with a fun story on “Silver Belle”... the first tree from Nevada to serve as the U.S. Capitol Christmas Tree!

Kissing, for all popularity, is a bit of a mystery. Scientists have long debated when humans’ ancestors first put their lips together, and whether the act is simply a cultural trait. A new study suggests giving someone a peck has a long history, dating up to around 21 million years ago, long before modern humans existed. The work was published in the journal Evolution and Human Behavior on November 19.

The first kiss in history probably took place over 16.9 million years ago — long before humans even existed, a new study suggests.

Each year during Hispanic Heritage Month, huge celebrations can be expected across the U.S. to showcase the diversity and culture of Hispanic people. This year, the Trump administration’s immigration crackdowns, a federally led English-only initiative and an anti-diversity, equity and inclusion push have changed the national climate in which these celebrations occur. Organizers across the country, from Massachusetts and North Carolina to California and Washington state, have postponed or canceled heritage month festivals altogether.

When Karen Harry first saw the artifacts, she snorted and shook her head. She simply did not believe that they were ancient cooking pots—everything about them looked wrong. Harry, a ceramics archaeologist at the University of Nevada, Las Vegas, works mostly in the desert Southwest of the United States, where Native Americans traditionally made some of the most elegant pottery in the world. But one day in 2003, a colleague at UNLV, Liam Frink, returned from a trip to western Alaska, where he had been excavating sites associated with the Thule people, the ancestors of the modern-day Inuit. Frink showed her the remains of some supposed cooking pots he had collected there. The pieces looked more like chunks of scorched dirt than typical potsherds—blackened and crumbling, like nothing Harry had ever seen.

In mid-August, the science journal Nature published UNLV research about a newly discovered species of human ancestors. A group of scientists traveled to Ethiopia, where they found 13 teeth fossils. Some of them belonged to the genus Homo — yes, the same genus modern humans belong to. But they also found a set of teeth that belonged to a new species of the genus Australopithecus, indicating that both species were present in Africa at the same time a little over 2 million years ago.
