The first week of November brings the end of Daylight Saving Time and return of Standard Time. Reporter Corey Olson sat down with UW Biology professor Horacio de la Iglesia to discuss the health benefits of staying in Standard Time permanently.

Over the course of some 44,000 years, humans occupying the island of Timor-Leste, just north of Australia, changed their methods of making stone tools in lockstep with climate change, according to a recent study in Quaternary Science Reviews. Ben Marwick, professor of anthropology at the UW, is quoted.

An interview with Dr. Loma Pendergraft on crow vocalization. Pendergraft — a current psychology lecturer in animal behavior-related classes — found interest in the noises the crows on the south side of the UW campus made as he fed them. This curiosity led to the experiment that comprised his master’s degree. 

Some are stubborn optimists. Others struggle with despair. Their faces show the weight they carry as they witness the impact of climate change. Kristin Laidre, associate professor of aquatic and fishery sciences at the UW and principal scientist at the Applied Physics Laboratory, and P. Dee Boersma, professor of biology at the UW, are featured.

A recent study reveals the fascinating evolutionary journey of bat teeth and jaws. With over 200 species mostly found in the American tropics, noctilionoid bats possess a wide variety of jaw structures that have adapted to different diets. Sharlene Santana, professor of biology at the UW, is quoted.

There are more than 200 species of noctilionoid bats, mostly in the American tropics. And despite being close relatives, their jaws evolved in wildly divergent shapes and sizes to exploit different food sources. A paper published Aug. 22 in Nature Communications shows those adaptations include dramatic, but also consistent, modifications to tooth number, size, shape and position. For example, bats with short snouts lack certain teeth, presumably due to a lack of space. Species with longer jaws have room for more teeth — and, like humans, their total tooth complement is closer to what the ancestor of placental mammals had.

Political Science professor James Long studies why many voters choose to participate in elections in emerging democracies despite the considerable personal cost.

What it means to be Black and Republican has changed through the years. American Ethnic Studies professor La TaSha Levy is researching a period of dramatic change for Black Republicans. 

Where do you seek information about politics and elections? In this roundtable, three faculty in the UW Department of Communication discuss the role of media in creating an informed public.

From dark matter to planet-crushing asteroids, four ways the telescope could alter our understanding of the universe. Mario Jurić, professor of astronomy at the UW, is quoted.

Artists and writers are up in arms about generative artificial intelligence systems—understandably so. These machine learning models are only capable of pumping out images and text because they’ve been trained on mountains of real people’s creative work, much of it copyrighted. Major AI developers including OpenAI, Meta and Stability AI now face multiple lawsuits on this. Emily M. Bender, professor of linguistics at the UW, is quoted.

"Killers of the Flower Moon," the Martin Scorsese movie about my people, the Osage Nation of Oklahoma, brings to life the reign of terror we lived through a century ago, as if we were back there on those busy 1920s reservation streets, rubbing elbows with our own ancestors and their murderers. It is a powerful film, vividly and heartbreakingly accurate," writes Jean Dennison, associate professor of American Indian Studies at the UW.

"The U.S. National Oceanic and Atmospheric Administration has reported that 2023 is already the most expensive year on record for weather and climate disasters in the U.S., with 23 separate disasters that have caused at least $1 billion each in estimated damages," writes Adrienne Russell, professor of communication and co-director of the UW Center for Journalism, Media and Democracy.

In a paper published Sept. 6 in Physical Review Letters, an international team of researchers in the United States, Germany and France reported that a distinctive strategy they have used shows real promise to be the first approach to measure the mass of the neutrino. Once fully scaled up, their collaboration — Project 8 — could also reveal how neutrinos influenced the early evolution of the universe as we know it.

When you hear a cover of a favorite song, comparisons are inevitable. There are obvious similarities – the lyrics, the melody – but there are also enough differences to make each version unique. Those deviations say more than you might expect. Maya Angela Smith, associate professor of French, introduces translation studies through the lens of the song "Ne Me Quitte Pas."
