Cancer Vaccines, Planting Wildflowers, Eating Copi Fish. August 5th, 2022, Part 1

White House Declares Monkeypox Outbreak A Public Health Emergency The Biden administration declared the monkeypox outbreak a public health emergency on Thursday. Earlier in the week the White House appointed Robert Fenton, regional administrator at FEMA to direct the federal government’s response to the monkeypox outbreak, along with a deputy director from the CDC. This comes after criticism from activists and public health experts, who have said that the federal government has been dragging its feet on access to vaccines, testing and treatment for the virus. Ira talks with Tim Revell, deputy United States editor for New Scientist, about the latest monkeypox updates and other top science stories including; new research into the shape of the human brain; how hand gestures can improve zoom calls and a plant that harnesses the power of a raindrop to gulp down insects.   New Steps Toward a Vaccine For Cancer Vaccines have long been used to prevent infection from viruses. But now, scientists are working on a different kind of vaccine—one that targets cancer. Dr. Kai Wucherpfennig is working on a cancer vaccine that would target tumors that tend to spread quickly and are resistant to treatment, like melanoma and triple negative breast cancer. This type of vaccine is intended to be used after a patient has had their tumor removed. The goal is to prevent the spread of cancer cells to other parts of the body, which is called metastasis. So far, this type of cancer vaccine is effective in animals, and the results were recently published in the journal Nature. Ira talks with Dr. Kai Wucherpfennig, chair of cancer immunology and virology at the Dana-Farber Cancer Institute and professor of neurology at Harvard Medical School, about his latest research into cancer vaccines, and how recent advances in understanding the immune system has jump-started research into new types of cancer immunotherapies.   Restoring A Sensitive Ecosystem, One Wildflower At A Time The New England blazing star is more than just a pretty blossom: it’s an integral part of a globally-rare ecosystem called a “sandplain grassland.” Just like the name suggests, sandplain grasslands have sandy soil with tall grass, no trees and an exceptionally high number of rare plant and animal species. That includes plants like the New England blazing star, an important food source for various grassland insects. Today volunteers would plant 1,000 of them to help restore Bamford Preserve, a 60-acre parcel of sandplain grassland on Martha’s Vineyard. As climate change threatens both human health and the natural world, experts say that protecting biodiversity hotspots like this one will offer the most bang-for-the-buck — protecting threatened species while offering other ecosystem benefits, like open space and flood protection.

The fish are not native to the U.S., but over the last few decades their populations have exploded in waterways like the Mississippi River Basin and the Illinois River. Over the last few years, there’s been a major PR campaign to move away from the name Asian Carp, in favor of a new name: “Copi.” The reason is two-fold: First, it joins a general trend of moving species’ names away from nationalistic associations, considering anti-Asian hate crimes during the COVID-19 pandemic. The other goal is to make the fish sound more delicious—creating a market that would incentivize fishing the Copi, hopefully reducing their populations. Joining Ira to talk about this is Jim Garvey, director of fisheries, aquaculture and aquatic sciences at Southern Illinois University in Carbondale, Illinois.   Transcripts for each segment will be available the week after the show airs on sciencefriday.com.     Subscribe to this podcast.
