View in browser Inside Science has stories about new ways to power satellites or look for life on Mars, about what bits of iron are doing in pigeon ears (they've ruled out navigation!), and about how cats listen for their owners. But that's not all. Climate change is here, and winemakers will need to adjust. In Australia, as Benjamin Plackett reports, that means grappling with heat waves that burn the fruit on the vine and the long-lasting effects of wildfires and their smoke, in addition to reduced rainfall. There's also a lot of research into capturing rainfall, reducing evaporation and assessing the amount of smoke that grapes have absorbed before a winemaker turns them into wine. We hope you'll read a few of these stories -- and if you haven't scrolled all the way down this email before, please do take a look to see the stories we highlight from other publications. —Chris Gorski, Senior Editor Featured Story Australian Winemakers Turn to Science to Help Weather Climate Change If the world can limit future greenhouse gas emissions, scientists are hopeful that adaptations can help a battered industry survive. By Benjamin Plackett, Contributor Inside Science's Latest Stories Cats Know Where Their Owners Are Experiments showed how cats can track their owners by listening for their voice.

Choi, Contributor What We're Reading Half of the World's Coastal Sewage Pollution Flows from Few Dozen Places By Nikk Ogasa, Scientific American   Sending untreated sewage into bodies of water is causing nitrogen pollution and algal blooms around the world. It's also spreading pathogens. But some new research has helped show where most of the pollution is coming from, which could help shape efforts to address the problems. Readers may also be curious to see some of Nikk's stories that Inside Science published last winter. Why health-care workers are quitting in droves By Ed Yong, The Atlantic This is just awful, difficult stuff to read. Responding to the pandemic has left serious wounds in the people who work in medical care. Many have quit. The consequences will continue to be felt for years and will likely affect health outcomes for the rest of us. One medical school dean told Yong that in meetings "when we go around the room, everyone says, 'We're struggling to retain our workforce.' Nobody says, 'We're fine.'" New mineral 'davemaoite' made an unlikely journey from the depths of the Earth By Emma Bowman and Ziad Buchh, NPR Deep underground, below the Earth's crust, conditions are extreme. The pressures and temperatures are high, and scientists believe that there are minerals found there that can't survive the conditions found up here. That's why scientists were so surprised to find an unfamiliar mineral inside a diamond that was mined in Botswana. The diamond provided the protection needed so that specks of the new mineral, called davemaoite, could survive the trip to the surface. This is the first mineral that's been spotted in nature that originated in the Earth layer known as the lower mantle. Read More from Inside Science Copyright 2021 American Institute of Physics.
