Earlier this year, Congress pushed back on the Trump administration’s attempts to slash funding for many science research programs, and restored that money to the budget. But despite the funds existing in the budget, they have <a href="https://www.sciencefriday.com/segments/slow-release-federal-science-funding-nih-nsf-nasa/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank" rel="noopener noreferrer">not yet been released</a> to some researchers. 
Science journalist Alexandra Witze joins Host Ira Flatow to walk through the details of the government funding process, and her recent <a href="https://www.nature.com/articles/d41586-026-00601-0" target="_blank" rel="noopener noreferrer">report in Nature</a> about the funding slowdown.

Some money allocated for scientific research has been restored to the federal budget, but the White House OMB has been slow to release it.

Slow Release Of Federal Science Funds Holds Up Research

In nature, enzymes are the catalysts that make much of biology work. They jumpstart chemical reactions that either wouldn’t happen, or would happen super slowly. They break down food, build other molecules, extract energy, and more. What if we could harness evolution to <a href="https://www.sciencefriday.com/segments/frances-arnold-enzyme-engineer-chemistry/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank" rel="noopener noreferrer">engineer designer enzymes</a> that do other specific jobs that benefit us? 
Putting that idea into practice changed the game for chemistry, and earned Frances Arnold the Nobel Prize prize in 2018. She called it “directed evolution.” Today, thousands of labs use her methods to coax enzymes into doing things no one ever thought of. She joins Host Flora Lichtman to talk about where she sees this approach going in the future, and the personal evolution that brought her into science.

Frances Arnold's game-changing technique of "directed evolution" creates enzymes with unusual capabilities. Her own evolution made it possible.

The Evolution Of An Enzyme Engineer Who Changed Chemistry

The new semi-autobiographical play “The Reservoir” spins a comedic <a href="https://www.sciencefriday.com/segments/preventing-dementia-cognitive-decline/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank" rel="noopener noreferrer">narrative around cognitive reserve</a>, the idea that doing brain-stimulating activities can prevent or delay the onset of dementia symptoms. It’s currently running at the Atlantic Theater Company and co-produced by The Ensemble Studio Theater in New York.* 
Host Ira Flatow talks with playwright Jake Brasch about his inspiration for the play and how to mesh science into the theater. 
Then, neurologist Marilyn Albert discusses some of the latest science of mental stimulation and dementia. After following a diverse group of older adults for 20 years, <a href="https://alz-journals.onlinelibrary.wiley.com/doi/10.1002/trc2.70197" target="_blank" rel="noopener noreferrer">her research</a> found that a modest amount of specialized cognitive training reduced dementia risk by 25%. You can try a <a href="https://www.brainhq.com/" target="_blank" rel="noopener noreferrer">very similar brain training exercise</a> at home. 
*“The Reservoir” received funding from the Sloan Foundation, which also helps support Science Friday. 
 Guests: 
 Jake Brasch is a writer, performer, composer, clown, and writer of the new play “The Reservoir.”

A new comedic play and a 20-year neurology study explore what we can do to prevent dementia and cognitive decline.

The Art And Science Of Staving Off Cognitive Decline

American chestnut trees once towered over the landscape, dominating forests in parts of the eastern United States. But in the late 1800s, a fungal blight <a href="https://www.sciencefriday.com/segments/restoring-american-chestnut-tree/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank" rel="noopener noreferrer">virtually wiped them out</a> across the country. Chestnut restoration scientist Jared Westbrook tells Host Ira Flatow how new genetic work could speed up efforts to breed fungal resistance into hybrid chestnuts and create a heartier chestnut population.  
 Then, author Hanna Lewis introduces Ira to the concept of miniforests, self-sustaining native forest ecosystems on a tiny footprint, like an empty lot or a schoolyard. The planting method, developed by botanist Akira Miyawaki, can help “rewild” small parcels of land by jump-starting forest development.

Genetic research could speed the restoration of the American chestnut tree. Plus, "rewilding" small spaces with fast-growing miniforests.

Into the Woods, From Chestnut Genetics To Tiny Forests

On February 12, the Environmental Protection Agency dealt a major blow to the government’s power to fight climate change by rescinding a key piece of research called the <a href="https://www.sciencefriday.com/segments/epa-rejects-key-greenhouse-gas-finding/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank" rel="noopener noreferrer">endangerment finding</a>. The finding, issued in 2009, basically says: Greenhouse gas emissions endanger public health and welfare—and because they’re harmful, they must be regulated. It's the legal basis for the federal government’s regulation of greenhouse gases under the Clean Air Act. So what does it mean that this finding has been thrown out?
Host Flora Lichtman digs into this question with Andy Miller, an original author on the endangerment finding who spent more than 30 years working for the EPA.

The endangerment finding forced the EPA to regulate greenhouse gas emissions. Now, the agency says it doesn’t have the authority to do that.
