The American Cancer Society published a study suggesting that for 8 or 34 cancers tracked, case rates are rising from one generation to the next. While headlines often point to sedentary lifestyles and higher weights as a possible cause, some experts say that these factors alone cannot explain the spike. In more hopeful oncology news, there’s a new blood test for colorectal cancer–though it doesn’t replace the importance of colonoscopies. SpaceX is delaying their attempt at the first-ever private spacewalk—billionaire Jared Isaacman will have to wait. And on the ground, move over hardwood and softwood—two surviving species of the Liriodendron genus point to a new categorization of midwood.Recommended reading:Gen X Faces Higher Cancer Rates Than Any Previous Generation Why We’ll Never Live in Space E-mail us at sciencequickly@sciam.com if you have any questions, comments or ideas for stories we should cover!

Gazing up at the night sky is a universal human experience, likely as old as our species itself. But how did our ancient ancestors feel about what they saw in the heavens, and how did it shape their lives? In Episode Two of our three-part Fascination miniseries on unusual archaeology, science journalist Kata Karáth introduces us to archaeoastronomy—the study of how people in the past experienced and explained the phenomena of the cosmos.Listen to the first episode of this series: “Sustainable Fishing with Ancient Chambers and Ocean Tides”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.Science Quickly is produced by Jeff DelViscio, Fonda Mwangi, Kelso Harper, Madison Goldberg and Rachel Feltman.

Sex testing has a long history in sports. As participation in events like the Olympics opened to women, organizers and audiences alike began questioning the sex of the athletes. The tests devised to “prove” an athlete’s sex have been invasive and inaccurate. Rose Eveleth, host of the NPR and CBC podcast Tested, brings us the story of sex testing and where the science stands.Listen to Tested: https://link.chtbl.com/zQEKpQCERead Olympic coverage from Scientific American:Is Technology in the Olympics a Form of Doping or a Reality of Modern Sport? https://www.scientificamerican.com/article/is-technology-in-the-olympics-a-form-of-doping-or-a-reality-of-modern-sport/For Olympic Athletes, First Come the Games—Then Come the Post-Olympics Blues https://www.scientificamerican.com/article/for-olympic-athletes-first-come-the-games-then-come-the-post-olympics-blues/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.Science Quickly is produced by Rachel Feltman, Fonda Mwangi, Kelso Harper, Madison Goldberg and Jeff DelViscio.

Fish trapping is an ancient practice, reaching across the globe from at least as far back as 11,000 years ago. It takes advantage of coastal tides and human-made chambers to catch and release fish. The simple but ingenious ancient fishing structures are built on two intertwining principles: the ocean can provide for us if we properly care for it.Archaeologists are mapping the possible locations of ancient traps. And on Penghu, a group of islands off of Taiwan, people are reviving the traditional tidal weirs, hoping to promote sustainable fishing and attract ecotourism. Stay tuned for more from science journalist Kata Karáth in part two of our three-part Fascination series on unusual archaeology.Recommended reading:– Oldest Deep-Sea Shipwreck Is a ‘Time Capsule’ from the Bronze Age– The Oldest-Wine-in-the-World Title Goes to a 2,000-Year-Old White Found in Southwestern SpainE-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. Science Quickly is produced by Rachel Feltman, Fonda Mwangi, Kelso Harper, Madison Goldberg and Jeff DelViscio.

Meditation is mostly mainstream, with many people using mindfulness to manage stress. But dedicated practitioners of advanced meditation move beyond mindfulness into a state where consciousness “entirely falls away.” That’s according to today’s guest: Matthew Sacchet, an associate professor and director of the Meditation Research Program at Harvard Medical School and Massachusetts General Hospital. Sacchet tells host Rachel Feltman about his journey from youthful meditator to neuroscience researcher. Plus, they discuss what meditation and psychedelic experiences are unlocking for consciousness researchers.Recommended reading:Read a feature co-authored by Sacchet in the July issue of SciAm And see our June issue feature on the neuroscience of near-death experiencesE-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. Science Quickly is produced by Rachel Feltman, Fonda Mwangi, Kelso Harper, Madison Goldberg and Jeff DelViscio.
