New AI Composes Songs From Silent Performance Videos There have been many awkward attempts in the quest to train algorithms to do what humans can. Music is a prime example. It turns out that the process of turning the individual notes of a composed piece into a fully expressive performance—complete with changes in loudness and mood—is not easy to automate. But a team at the University of Washington has been closing in on a way to get close, in research they presented at a machine learning

What Does The Future Look Like For COVID-19 Long-Haulers? There’s something strange happening with some people who’ve gotten sick with COVID-19: Somewhere between 10 and 30% of people who are infected are stuck with long-lasting effects and complications. People dealing with long-term symptoms after a coronavirus infection are known as COVID long-haulers, and as the pandemic gets longer, their numbers grow. Long-haul COVID is still a mystery in a lot of ways, but work is being done to understand

The Buzz Over Non-Bee Pollinators When you think of pollinators, bees are probably the first insect that comes to mind. But there are actually all sorts of insects and animals that contribute to pollination, like moths, beetles and many kinds of flies—from hoverflies to gnats. Pollination biologist Robert Raguso joins SciFri to explain how different pollinators have different ‘personalities,’ with different strategies and roles—and how they are being affected by climate change.

The collider is currently cooling down and testing components, and aiming to start up for its third major run late this year. In the meantime, researchers have had time to sift through the data from previous experiments—and last

Some businesses have limited hours, others have capacity restrictions. Still other businesses are temporarily closed. Some are gone altogether. The pandemic has also had other financial effects that are harder to see—and often, that financial stress is hitting the same people who are already most likely to have gotten

The Mental Health Costs Of ‘Everyday’ Racism On March 16, a 21-year-old white man killed six Asian women and two other people in multiple shootings in Atlanta. Since the start of the COVID-19 pandemic, Asians and Asian-Americans in the U.S. have experienced a rise in racist attacks, which psychologists say are tied to anti-Chinese rhetoric from the former White House administration, as well as others who have scapegoated Asian Americans. The Stop AAPI Hate reporting center was created in March of

SciFri Extra: The Origin Of The Word 'Introvert'

Science Diction from Science Friday is back! Their latest episode is all about a recent buzzword: "Introvert." In 2013, introverts staged their comeback. For decades, they’d been told to get out of their shells and *smile*, while those showy, gregarious extroverts were held up as the American ideal. But when one author published a kind of introvert’s manifesto, she sparked an introvert pride movement. Since then, the war of the ‘verts has only escalated, with self-identified introverts accusing

Under A Mile Of Ice, A Climate Clue Scientists studying sediment taken from a core sample of the Greenland ice sheet just 800 miles from the North Pole have found remnants of ancient plants, freeze-dried under more than a mile of ice. Using several different dating techniques, they say the soil, twigs, and leaves date to sometime within the last million years—probably on the order of several hundred thousand years ago—a time when Greenland’s massive ice cap did not exist. The finding that the ice

In 2005, the massively multiplayer online video game World Of Warcraft introduced a special event raid, where groups of players could team up to fight a giant snake demon named Hakkar the Soulflayer. Hakkar would cast a spell called “Corrupted Blood” on players, which would slowly whittle down their health. The effect of the spell was only

What Went Wrong With Jackson, Mississippi’s Water? Residents of Jackson, Mississippi have been dealing with a water crisis since a storm rolled through town on February 15th. The city’s water system was damaged, leaving thousands of residents without running water at home. People have relied on water distribution sites to get by, and even those who can still use their taps are on boil water notice. Impacted residents are largely low-income, and the limited access to water has raised worries about

In the November election, voters passed ballot Measure 110 by a 16-point margin. Now, if you’re caught with one or two grams of what some refer to as “hard drugs”, you won’t be charged. Instead, you’ll either pay a maximum $100 dollar fine, or complete a health assessment within 45

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

Memory And The Dreaming Mind If you’ve ever stayed up too late studying for a test, you know that sleep impacts memory—you need that precious shut-eye in order to encode and recall all that information. But what is it about sleep that aids memory? Researchers have pinpointed a specific stage of sleep, REM sleep, as an area of interest for studying memory consolidation. REM, or rapid eye movement sleep, is the same stage in which dreams occur. So researchers at Northwestern University devised a way

As one California biologist recently learned, the eyes of Chinook salmon are like a tiny diet journal of everything it ate. But to read that journal, you have to peel back the layers of the eye, like it’s the world’s tiniest onion.

National Bison Range Returns To Indigenous Management Hundreds of years ago, tens of millions of bison roamed North America. They were an essential resource and cultural foundation for many Native American tribes. And by 1890, European colonists had hunted them nearly to extinction. When President Theodore Roosevelt moved to conserve the remaining bison in 1908, he established the National Bison Range, an 18,800-acre reserve that the government took directly from the tribes of the Flathead
