A future in which your hamburger is grown from animal cells in a lab is rapidly approaching. The idea is that by culturing meat in a vat, you not only cut down on animal slaughter but greatly reduce emissions, on account of cattle taking a lot of energy to raise and butcher and ship. That's…

This story originally appeared on Slate and is part of the Climate Desk collaboration. Two weeks ago, the Intergovernmental Panel on Climate Change released a dire report that made crystal clear that we have about a decade to stop catastrophic levels of climate change. The report caught fire for another extremely near deadline: It suggests…

Nobel laureate Richard Feynman once asked his Caltech students to calculate the probability that, if he walked outside the classroom, the first car in the parking lot would have a specific license plate, say 6ZNA74. Assuming every number and letter are equally likely and determined independently, the students estimated the probability to be less than…

In 1994, a mathematician at AT&T Research named Peter Shor brought instant fame to “quantum computers” when he discovered that these hypothetical devices could quickly factor large numbers — and thus break much of modern cryptography. But a fundamental problem stood in the way of actually building quantum computers: the innate frailty of their physical…

In 2015, the U.S. Naval Academy decided that its graduates needed to return to the past and learn how to navigate using the stars. Nine years prior, it had dropped celestial navigation from its requirements because GPS was so accurate and simple to use. But recent events had shaken the academy’s faith in GPS. Researchers…

You might have already passed that silly course with a title something like "Introductory Algebra and Trigonometry." It covered a bunch of stuff, but the important part was that the class was a prerequisite for your physics course. But do you really understand the very basic concepts of trig? Yes, I just call it "trig"…

I can imagine the meeting: A dozen engineers are gathered around a conference table to discuss automobile safety. How can we protect people during a car crash? We have already added seat belts and crumple zones to cars. Is there anything else we can include? One attendee reluctantly raises their hand with a suggestion: "How…

Last Thursday, a shiny new SpaceX Falcon 9 rocket sat perched atop NASA’s historic Pad 39A, at Florida’s Kennedy Space Center, waiting to briefly fire its engines. The exercise was part of a routine prelaunch test. What wasn’t routine was the presence of a Crew Dragon capsule atop the slick black-and-white Falcon. The domed capsule,…

In Katowice, Poland, delegates from around the world have gathered to discuss how to curb emissions of greenhouse gases. The intent is to meet the goals that emerged from the 2015 Paris United Nations Climate Summit. But this year there’s a new top dog at the table. The United States, led by a president who…

Delaney Van Riper was exhausted. It was the summer of 2017 and she’d spent the previous day touring UC Santa Cruz’s cliffside campus, getting her student paperwork in order, and meeting some of her 4,000 fellow incoming Slugs. Now, dressed head-to-toe in sweats, she was ready to nap in the backseat for the ride to…
