Who shares fake news? Political scientists, behavioral researchers and the media have said that political conservatives are largely responsible for the proliferation of misinformation. But although there is a documented association, not all conservatives share fake news or endorse such behavior. Such sweeping generalizations threaten to condemn everyone who subscribes to conservative values, and that,… Continue reading Personality Type, as well as Politics, Predicts Who Shares Fake News

Christopher Intagliata: This is Scientific American’s 60-Second Science. I’m Christopher Intagliata. Just as cows, sheep and bison roam in herds today, so, too, did plant-eating dinosaurs. And it appears they began flocking together much earlier than we used to think—just as the Jurassic period began to unfold. Jahandar Ramezani: This is a critical time in the… Continue reading Flocking Together May Have Helped Dinosaurs Dominate the Earth

Most American newborns will arrive home from the hospital and start hitting their developmental milestones, to their parents’ delight. They will hold their heads up by about three months. They will sit up by six. And they will walk around their first birthday. But about 1 in 10,000 will not. They will feel limp in… Continue reading The Rise of RNA Therapeutics – Issue 107: The Edge

When you deposit a quarter and turn the crank on a gumball machine, the flavor you receive is basically random. In math, sometimes a polynomial, like x2 + y2, works the same way. When you plug in numbers for x and y, the values the polynomial takes might be random. Other polynomials might favor particular… Continue reading Mathematicians Find Structure in Biased Polynomials

GLASGOW, Scotland—As climate talks race toward their conclusion, a concerted push by vulnerable countries to shake the world into taking action against intensifying threats from the sea and sky might be inching forward on the world stage. For days negotiators have huddled in windowless rooms trying to hammer out deals about funding and winding down… Continue reading Adaptation Becomes Focus of Climate Summit as Talks Draw to a Close

All around the world, sewage gushes out of pipes into rivers and the sea, threatening the health of humans and aquatic ecosystems. Though some individual sites have long been known to be major sources of coastal pollution, “we’ve never had a global understanding of how big the problem is,” says Cascade Tuholske, a geographer at… Continue reading Half of the World’s Coastal Sewage Pollution Flows from Few Dozen Places

Yet the task may not be impossible. Just as currents in the Escher-like ocean can be deciphered from their shadows on its boundary, perhaps theorists can read the inflationary story from its final cosmic scene. In recent years, Baumann and other physicists have sought to do just that with a strategy called bootstrapping. Cosmic bootstrappers… Continue reading Laws of Logic Lead to New Restrictions on the Big Bang

People who are into physics and follow blogs actively have surely ran into MIT physicist Scott Aaronson, probably most well known for his critiques of the alleged D-Wave quantum computer. More recently, Scott has been writing a lot about consciousness, but his latest post – prepared talk notes from the Quantum Foundations of a Classical Universe meeting – is a… Continue reading “Could a quantum computer have subjective experience?” by Scott Aaronson — Mostly Physics

Maynard Okereke is using his distinctive voice to fight the lack of minority representation in STEM Credit: Maynard OkerekeAdvertisement For many of us, the past year and a half may have seemed to slow way down. And in fact, some studies have shown just this. But Maynard Okereke’s life has been anything but slow recently.… Continue reading This Engineer, Actor and Science Communicator Is Giving Science Its Rap

Mathematicians draw bifurcation diagrams (the simplest look like pitchforks) to analyze how the states of a system respond to changes in their parameters. Often, a bifurcation divides stability from instability; it may also divide different types of stable states. It’s useful in studying systems associated with mathematical chaos, where small changes in the starting point… Continue reading A New Theory for Systems That Defy Newton’s Third Law
