Receptors that give our feline friends a craving for meat, and using combustion to propel insect-size robots
First up on this week’s episode, Online News Editor David Grimm joins host Sarah Crespi to talk about why despite originating from a dry, desert environment cats seem to love to eat fish.
Next on the show, bugs such as ants are tiny while at the same time fast and strong, and small robots can’t seem to match these insectile feats of speed and power. Cameron Aubin, a postdoc at Cornell University who will shortly join the University of Michigan, discusses using miniscule combustion reactions to bring small robots up to ant speed.
Finally in a sponsored segment from the Science/AAAS Custom Publishing Office, Jackie Oberst, associate editor for custom publishing, discusses with Bobby Soni, chief business officer at the BioInnovation Institute, an international life science incubator in Copenhagen, Denmark, what it takes to bring a product from lab to market and how to make the leap from scientist to entrepreneur. This segment is sponsored by the BioInnovation Institute.

Folge vom 07.09.2023Extreme ocean currents from a volcano, and why it’s taking so long to wire green energy into the U.S. gridHow the Tonga eruption caused some of the fastest underwater flows in history, and why many U.S. renewable energy projects are on hold First up on this week’s show, we hear about extremely fast underwater currents after a volcanic eruption. Producer Meagan Cantwell talks with sedimentary geologist Michael Clare and submarine volcanologist Isobel Yeo, both at the U.K. National Oceanography Centre. They discuss the complex aftermath of the Hunga Tonga-Hunga Ha’apai eruption, including fast and powerful ocean currents that severed seafloor cables. Watch a related video on last year’s eruption by Meagan: How the Tonga volcanic eruption rippled through the earth, ocean and atmosphere. Next on the show, an unexpected slowdown in connecting renewable power to the electrical grid. Freelance journalist Dan Charles joins host Sarah Crespi to discuss how problems with modeling energy flow in the electrical grid are holding up wind and solar power projects across the country.

Folge vom 31.08.2023Reducing calculus trauma, and teaching AI to smellHow active learning improves calculus teaching, and using machine learning to map odors in the smell space First up on this week’s show, Laird Kramer, a professor of physics and faculty in the STEM Transformation Institute at Florida International University (FIU), talks with host Sarah Crespi about students leaving STEM fields because of calculus and his research into improving instruction. We also hear from some Science staffers about their own calculus trauma, from fear of spinning shapes to thinking twice about majoring in physics (featuring Kevin McLean, Paul Voosen, Lizzie Wade, Meagan Cantwell, and FIU student and learning assistant Carolyn Marquez). Next on the show, can a computer predict what something will smell like to a person by looking at its chemical structure? Emily Mayhew, a professor in the department of food science and human nutrition at Michigan State University, talks about how this was accomplished using a panel of trained smellers, and what the next steps are for digitizing the sense of smell.

Folge vom 24.08.2023The source of solar wind, hackers and salt halt research, and a book on how institutions decide genderA close look at a coronal hole, how salt and hackers can affect science, and the latest book in our series on science, sex, and gender First up on this week’s show, determining the origin of solar wind—the streams of plasma that emerge from the Sun and envelope the Solar System. Host Sarah Crespi talks with Lakshmi Pradeep Chitta, a research group leader at the Max Planck Institute for Solar System Research, about how tiny jets in so-called coronal holes seem to be responsible. Sarah also talks with Science Editor Keith Smith about the source of the data, the Solar Orbiter mission. Read a related Perspective. Next, two stories on unlikely reasons for slowing science. First, cyberattacks on telescopes scramble ground-based astronomy in Hawaii and Chile, with Diverse Voices Interns Tanvi Dutta Gupta and Celina Zhao. Also, we hear about an unparalleled water crisis in Uruguay that has left scientists high and dry, with science journalist María de los Ángeles Orfila. Finally, in this month’s books segment in our series on science, sex, and gender, host Angela Saini talks with author and political scientist Paisley Currah about his book, Sex Is as Sex Does: Governing Transgender Identity, on why and how government institutions categorize people by sex and gender.
