Does A Vaccine Help You If You’ve Already Had COVID-19? Vaccines doses have started to rollout and are getting into the arms of people. We know that if you already had COVID-19, you build up antibodies against the virus. So do the vaccines affect you if you’ve already had COVID-19?  Science writer Roxanne Khamsi talks about recent studies showing that a single dose of vaccine could boost immunity for former COVID-19 patients. She also discusses a study that found over 140,000 viral species in the human gut and Elizabeth Ann, the first cloned black-footed ferret. The Aftermath Of Texas’ Winter Storm While power has been mostly restored, journalists report Texans are now facing water shortages, housing damage, and crop losses.  Texas grocery store shelves have begun filling out again. But for the state’s agriculture industry, recovering from the winter storm will take time, and consumers are likely to feel it in their pockets. The historic freeze and power outages brought agriculture across the state to a halt. Dairy farmers were forced to dump gallons of unpasteurized milk for days as processing plants were left without power. Packing houses also shut down with machinery cut off from electricity and employees unable to make their shifts, said Texas Agriculture Commissioner Sid Miller. Meanwhile, the products on the market were quickly bought up by panicked Texans just before and after the storm. By Monday, Miller said he had seen the price of hamburgers go up to $8.50 a pound, and he expects prices to remain elevated as the food supply chain stabilizes. “It’s not going to be back to normal for at least six to eight weeks,” Miller said. “You’ll still see shortages of some stuff, and even though the shelves may be full, the prices will be high.” Read and listen to the full story in the State of Science series.  Keeping An Eye On The Climate, From Space The climate is changing, and so is the U.S. government’s approach to it. The Biden White House has made the climate crisis a high priority, and has created several new positions focused on climate science. One of those new climate posts can be found at the space agency NASA. While rockets and Mars rovers may seem far removed from climate issues, NASA is actually the lead federal agency in climate observations, with a fleet of satellites tracking everything from sea temperature to CO2 levels to chlorophyll. Ira talks with Gavin Schmidt, who has recently been named in an acting role to be the senior climate advisor for NASA. He’s also director of NASA’s Goddard Institute for Space Studies in New York. They discuss upcoming climate-focused NASA programs, last week’s cold weather in Texas, and the challenge of making better decisions in an uncertain climate future. Subscribe to this podcast.
