Running an entire marathon takes a lot of energy. Neuroscientist Carlos Matute knows this: he's run 18 of them. He wondered how runners' bodies get the energy they need to make it to the finish line.
His new research in the journal Nature Metabolism may be the first step in answering the question – and suggests their brains might be (temporarily) depleting a fatty substance that coats nerve cells called myelin.

Consider This from NPR - Trump takes aim at trade deficits. Are they actually bad?
Whatever you think of President Trump's tariffs, there's one point you have to concede: his interest in them is not a passing whim.
He noted that on Wednesday, in the Rose Garden, when he was announcing the latest, massive round of tariffs. "I've been talking about this for 40 years," he said.
The use of tariffs are a core belief for Donald Trump. Trade deficits are bad, other countries take advantage of the U.S. and tariffs are the way to fix this.
Since the Rose Garden announcement, markets have plunged, other countries have promised to retaliate, and members of his own party have spoken out against the tariffs.
Trump's tariff plan is designed to eliminate U.S. trade deficits. Are trade deficits actually bad?

1A - What Detainments At Universities Mean For The First Amendment
The arrest and detainment of Columbia University graduate student Mahmoud Khalil by Immigration and Customs Enforcement garnered national attention.
Last week, the video of the arrest of a Turkish PhD student at Tufts University, Rumeysa Ozturk, by masked federal agents received similar attention.
In addition to Ozturk and Khalil, nearly a dozen international students and faculty at universities across the country have been detained for possible deportation as part of President Donald Trump's crackdown on those who've voiced pro-Palestinian views.
The arrests have raised questions — not just about the rights of immigrants with legal status in the U.S. — but about the right to dissent, regardless of citizenship, under the Trump administration.

1A - ICYMI: A Quarter Of HHS Workforce Lost Due To Cuts
The Trump administration's cutbacks to the federal workforce continued this week at the Department of Health and Human Services.
Thousands of staffers were fired at agencies like the Food and Drug Administration and the Centers for Disease Control and Prevention. HHS Secretary Robert F. Kennedy Jr. announced the layoffs last week, an additional "reduction in force" of 10,000 people on top of the 10,000 who've already left the department this year. This amounts to one of the largest government departments losing a quarter of its workforce.
One of the agencies affected is the National Institutes of Health. The network of research centers funds much of the country's biomedical research.
We discuss what the layoffs at the NIH mean for the country's ability to research and develop medical treatments.

NPR's Book of the Day - To confront radical change, ‘Slate’ writer Scaachi Koul wrote a new book of essays
Three years ago, Scaachi Koul went through a divorce, a process that she says was "disorienting." But divorce, the Slate writer says, also offered a framework for rethinking everything: her relationship with men, family, conflict, and herself. Her new book of essays Sucker Punch works through this personal evolution. In today's episode, Koul speaks with NPR's Leila Fadel about one of the primary relationships in these essays: the writer's relationship with her mother. They also discuss Koul's shifting perspective on fights, her interest in speaking with the man who sexually assaulted her, and her loose interpretation of Hindu fables.
