Griefbots Offer AI Connections with Deceased Loved Ones
Griefbots, artificial intelligence chatbots that mimic deceased loved ones, are increasingly in popularity. Researcher Katarzyna Nowaczyk-Basińska reflects on what death, grief and immortality look like in the digital age. She shares insights from a project that she is leading as a AI2050 Early Career Fellow: Imaginaries of Immortality in the Age of AI: An Intercultural Analysis. Plus, we discuss the ethical and privacy concerns surrounding how the data of the deceased are used and what consumers should be on the lookout for if they want to use griefbots.

Our Fear and Fascination around Snakes
When writer Stephen S. Hall was a child, he would capture snakes—much to his mother’s chagrin. Now the science journalist is returning to his early fascination In his latest book, Slither: How Nature’s Most Maligned Creatures Illuminate Our World. The book explores our long, complicated relationship with snakes. Plus, Hall chats about humans’ and other animals’ evolved reactivity to the presence of snakes and the adaptations that keep snakes alive in even the most extreme environments.Recommended reading:Slither is out now: https://www.hachettebookgroup.com/titles/stephen-s-hall/slither/9781538741337/ An Evolutionary ‘Big Bang’ Explains Why Snakes Come in So Many Strange Varietieshttps://www.scientificamerican.com/article/an-evolutionary-big-bang-explains-why-snakes-come-in-so-many-strange-varieties/ Venomous Snakes May Spread into Vulnerable Communities because of Climate Change https://www.scientificamerican.com/article/venomous-snakes-are-spreading-because-of-climate-change/ E-mail us at sciencequickly@sciam.com if you have any questions, comments or ideas for stories we should cover!Discover something new every day: subscribe to Scientific American and sign up for Today in Science, our daily newsletter.

Childhood Illnesses Surge, Magnetic Poles Wandered, and a Colossal Squid Is Found
Measles cases are going up—and a federal scientist has warned that case counts have probably been underreported. Another vaccine-preventable illness, whooping cough, sees a troubling increase in cases. Ancient humans found sun-protection solutions when Earth’s magnetic poles wandered. A colossal squid has been captured on video in its natural habitat for the first time. Plus, we discuss evidence that Mars once had a carbon cycle and a planet that is orbiting a pair of brown dwarfs.

A Long Day on Uranus, a Better Method of Making Coffee and Dinos Fossils in Decline
Caffeine-motivated researchers find that pour height may be the key to a perfect cup of coffee. A new study of plastics finds that less than 10 percent of such products are made with recycled materials. And once the plastics are used, only 28 percent of them make it to the sorting stage—and only half of that plastic is actually recycled. Data from the Hubble Telescope show how a day on Uranus lasts longer than previously thought. Plus, we discuss how scientists thought dinosaurs were in decline even before their mass extinction—until now.

How Are Prenatal Blood Tests Detecting Cancer?
Noninvasive prenatal blood testing, or NIPT, is a routine screening that is offered during pregnancy and looks for placental DNA to diagnose chromosomal disorders in a fetus. But in some cases, these tests can also find cancer in the pregnant person. How do the tests work, and why are they uncovering cancer? Genetic counselor and writer Laura Herscher speaks with host Rachel Feltman about IDENTIFY (Incidental Detection of Maternal Neoplasia through Non-invasive Cell-Free DNA Analysis), a broader study that seeks to understand why usual results from NIPT can correlate with a cancer diagnosis in a pregnant patient. Plus, we discuss why treating pregnant patients for cancer can be complicated for obstetricians and oncologists.Recommended reading:A Prenatal Test of the Fetus Turns Up Cancers in Pregnant Mothers https://www.scientificamerican.com/article/a-prenatal-test-of-the-fetus-turns-up-cancers-in-pregnant-mothers/ E-mail us at sciencequickly@sciam.com if you have any questions, comments or ideas for stories we should cover!Discover something new every day: subscribe to Scientific American and sign up for Today in Science, our daily newsletter.

Treating Bacterial Vaginosis as an STI Could Improve Outcomes
Bacterial vaginosis (BV), an overgrowth of pathogenic bacteria in the vagina, affects nearly one in three people with a vagina. While you can get BV without ever having sex, a new study has found that, in some cases, it could be functioning more like a sexually transmitted infection. That’s in part because of the increased risk of BV after sex with a new partner and a high recurrence of BV symptoms after treatment.The study examined women with BV who were in a monogamous relationship with a male partner and found that treating both people was significantly more effective than treating the woman alone. Host Rachel Feltman speaks with study co-authors Lenka Vodstrcil, a senior research fellow at Melbourne Sexual Health Center at Monash University in Australia, and Catriona Bradshaw, a professor of sexual health medicine at Monash University and Australia’s Alfred Hospital.Recommended reading:Read the studyResources for patients and health professionals E-mail us at sciencequickly@sciam.com if you have any questions, comments or ideas for stories we should cover!Discover something new every day: subscribe to Scientific American and sign up for Today in Science, our daily newsletter.
