Congress Has a $95 Million Proposal to Study Tech’s Effect on Kids
Like a lot of people, you probably spend a fair bit of time worrying about how much time you spend on your phone. Who doesn't these days? But what really concerns you is the youth. What is all that swiping and snapping and gramming doing to their still-developing brains? Surely somebody's studied this—the effect of…
How Our Biological Clock Could Dictate Medical Treatments
You might think the time on the clock controls when and how you live your life. But ticking away inside each of us is a biological timekeeper that holds powerful sway over our bodies and behaviors. When we eat and when we sleep, our heart rates and our hormones—they're all regulated by our so-called circadian…
Your Next Weather Apocalypse: The Smokestorm
This story originally appeared on Grist and is part of the Climate Desk collaboration. As wildfire smoke descended on Seattle last week, the sun turned an apocalyptic shade of red and the city breathed in some of the unhealthiest air in the world. A new word to describe this phenomenon graced the headlines: “smokestorm.” The person who coined the…
Two Satellites Almost Crashed. Here’s How They Dodged It
The first alert came on January 27. Two small satellites, whirling through Earth's low orbits, had “the potential for a conjunction.” Those are the words Major Cody Chiles, spokesperson for the Joint Force Space Component Command, uses to mean "the chance of a collision." The satellites, one from a company called Capella Space and the…
Inside the High-Stakes Race to Make Quantum Computers Work
Deep beneath the Franco-Swiss border, the Large Hadron Collider is sleeping. But it won’t be quiet for long. Over the coming years, the world’s largest particle accelerator will be supercharged, increasing the number of proton collisions per second by a factor of two and a half. Once the work is complete in 2026, researchers hope…
Estimate the Friction Coefficient in That Massive Nascar Pile-Up
I don't normally watch many NASCAR races, but I do come across some NASCAR videos online. Sometimes these clips become the basis of a great physics problem. In this case, it's a 21-car crash at the Daytona 500 earlier this week. There are two things I find amazing about it: First, that a tiny collision…
A Mushroom Extract Might Save Bees From a Killer Virus
The bees, as you've probably heard, are dying, in massive numbers. Termed colony collapse disorder, the die-off counts among its causes a parasite aptly named Varroa destructor. A flat, button-shaped, eight-legged critter no more than 2 millimeters long, varroa mites invade honeybee hives around the world in droves, latch onto their inhabitants, and feed on…
How Boston Dynamics' Robot Videos Became Internet Gold
Boston Dynamics’ videos aren’t just famous, at this point they are almost a staple of the internet—typical stuff like robots doing backflips and opening doors for their friends. But the machines only became a YouTube phenomenon because someone grabbed the first video from Boston Dynamics’ website and uploaded it themselves. “We just had it on…
In This Brutal Titan Games Event, Friction Is The Real Winner
I'm not sure what it is, but something keeps drawing me into physical competition shows. It used to be Ninja Warrior, but now there is a new one—Titan Games. It's essentially a competition with different crazy events. It's not the competition that I like, it's those weird situations that they put these people in. I…
Is the Universe a Hologram? Maybe! This Math Trick Shows How
The fabric of space and time is widely believed by physicists to be emergent, stitched out of quantum threads according to an unknown pattern. And for 22 years, they’ve had a toy model of how emergent space-time can work: a theoretical “universe in a bottle,” as its discoverer, Juan Maldacena, has described it. Quanta Magazine…
