Whenever your smartphone or video game console breaks down, you usually have to go back to the manufacture or a technician affiliated with the company to have your device fixed. Oftentimes, companies don’t release parts or guides to their devices, making it difficult to repair them own your own. 20 different states have introduced right-to-repair legislation, which calls for companies to open up the ability for individuals to fix their own devices. Recently, senator Elizabeth Warren called for a

Maple tapping season is underway in the sugar maple stands of the United States. Warm days and below-freezing nights kick off a cycle of sap flow crucial for maple syrup production. But why is the flow of sap so temperature dependent in sugar maples? University of Vermont maple researcher Abby van den Berg explains how ice crystals in the trees’ cells power sap flow, while Yale University’s Craig Brodersen tackles how other trees and plants move gallons of fluid per day from roots to leaves—all

April is National Poetry Month, a time of readings, outreach programs, and enthusiastic celebration of the craft. And for a special Science Friday celebration, we’ll be looking at where science and poetry meet. Tracy K. Smith, the current U.S. poet laureate, wrote the 2011 book Life On Mars, which touches on dark matter, the nature of the universe, and the Hubble Telescope—all as an elegy for her deceased engineer father, Floyd. Rafael Campo, a physician, poet, and editor for the Journal of the

Once upon a time, everything in the universe was crammed into a very small space. Then came the Big Bang, and the universe has been expanding ever since. But just how fast is it expanding? Calculating that number is a challenge that dates back almost a hundred years, when Edwin Hubble used data from Harvard astronomer Henrietta Swan Leavitt to try to answer that question. His value came to be called the Hubble constant, H0. But the exact value of that constant has been hard to pin down. And now two

When you go to the doctor’s office, it can sometimes seem like wait times are getting longer while face time with your doctor is getting shorter. In his book, Deep Medicine: How Artificial Intelligence Can Make Healthcare Human Again, cardiologist Eric Topol argues that artificial intelligence can make medicine more personal and empathetic. He says that algorithms can free up doctors to focus more time on their patients. Topol also talks about how A.I. is being used for drug discovery, reading

There’s been a changing of the guard in the U.S. House of Representatives. In January, Representative Eddie Bernice Johnson, a democrat from Texas, took over as chair of the House Committee for Science, Space, and Technology from her predecessor Lamar Smith. Smith was in charge of the House Science Committee for six years—an era that was defined by partisan attacks on climate science, and the issuing of congressional subpoenas to scientists. Chairwoman Johnson is looking to restore credibility to

Primatologist Frans de Waal has spent his lifetime studying the lives of animals, especially our closest cousins, the chimpanzees. de Waal has observed their shifting alliances and the structure of their political ranks. He has seen bitter conflicts break out, only to be mended by peaceful, respected mediators. And he has witnessed chimpanzees grieve for, and attempt to comfort, their dead and dying. But one of the most touching reflections in his new book, Mama’s Last Hug: Animal Emotions and What

It all started with 16-year-old environmental activist Greta Thunberg. Last August, Thunberg started skipping school on Fridays to protest outside Sweden’s parliament, insisting her country get behind the Paris Climate Agreement. Her protests have inspired thousands of young people around the world to join the #FridaysForFuture movement, skipping school to demand that their governments take action against climate change. And on Friday March 15th, these young people will take things a step

SciFri Extra: Celebrating The Elements

2019/03/12

Do you have a favorite chemical element? Neurologist Oliver Sacks did—he was partial to dense, high melting-point metals, especially those metals between hafnium and platinum on the periodic table. This month marks the 150th anniversary of chemist Dmitri Mendeleev’s design for the periodic table—and we didn’t want to miss out on the party. In this special podcast, we revisit Sacks’ fascination with the elements, and Ira opens up the Science Friday vaults to share two tales of chemical discovery and

Nearly twelve years ago, a cancer patient infected with HIV received two bone marrow transplants to wipe out his leukemia. Now, researchers in the United Kingdom reported in Nature earlier this week that their patient, a man known only as “the London patient,” had been in remission and off anti-retroviral therapy for 18 months after undergoing a similar bone marrow transplant, with the same gene mutation involved, to treat leukemia. While the team is hesitant to call their patient cured, he is the
