Evolutionary Biologist Neil Shubin, Bee Virus Behavior, Search for Lost Apples. May 1, 2020, Part 2 from Science Friday

From Science Friday - The Twists And Turns Of The Evolution Of Life On Earth In an evolutionary tree, neat branches link the paths of different species back through time. As you follow the forking paths, you can trace common ancestors, winding down the trunk to see the root organism in common.  Evolution in the real world is a little messier–full of dead ends and changes happening beneath the surface, even before new traits and species appear. And the research and science that gave us a better picture about how life evolved on Earth can just be just as complicated.   Evolutionary biologist Neil Shubin, author of Some Assembly Required: Decoding Four Billion Years of Life, from Ancient Fossils to DNA, explains how technology like DNA sequences has allowed scientists to fill in these gaps in the story of evolution.  A Viral Battle In The Honey Bee Hive New research published this week in the Proceedings of the National Academy of Sciences indicates that honey bees infected with a virus may alter their behavior in ways that slow the spread of the infection. At the same time, infection with the virus may help the bees sneak into neighboring hives, potentially spreading the virus to new hosts. Adam Dolezal, an assistant professor of entomology at the University of Illinois at Urbana-Champaign and one of the authors of the study, describes the research, and the evolutionary arms race that may be taking place between the bees and the virus. The Malus Domestica Detectives Earlier this month, the Lost Apple Project in Washington state announced a fruitful bounty: Ten varieties of apples found in the Pacific Northwest that had been considered "lost" varieties. These include the Sary Sinap, originally from Turkey, and the Streaked Pippin from New York. To find these varieties, the researchers used an old school identification process–the partner organization, Temperate Orchard Conservancy, compared the mystery apples to watercolor paintings commissioned by the USDA from the 1800s and early 1900s. It's a time consuming process, and positive identification can take years. Joining Ira to talk apple identification are Shaun Shepherd, pomologist at the Temperate Orchard Conservancy in Portland, Oregon, and Gayle Volk, plant physiologist at the USDA in Fort Collins, Colorado.

Fauci Says Majority Of U.S. Adults Likely To Be Vaccinated By Late Summer We're about a month shy of a big anniversary: one year since the World Health Organization officially labeled COVID-19 a pandemic. Since then, a lot has changed–and a lot has not. We have more information than ever about...

Fish Eye Secrets, Human Genome Project, Science Diction 'Mesmerize.' Feb 12, 2021, Part 2
Seeing The World Through Salmon Eyes The saying goes, "The eyes are the window to the soul." But for fish, the eyes are the window to the stomach.  As one California biologist recently learned, the eyes of Chinook salmon are like a tiny diet journal of everything it ate. But to read that journal,...

The Effectiveness Of Double-Masking, Mars Landing Preview. Feb 12, 2021, Part 1
Two Masks Are Better Than One Masks have been a big issue throughout the pandemic, from supply shortages to debates about when they should be required to be used. This week, the Centers for Disease Control and Prevention put out research and guidance on the effectiveness of double masking–wearing...
