Vertical Farming Has Found Its Fatal Flaw

In June, a vast new vertical farm opened on the outskirts of the English town Bedford. At a swanky opening event, members of the UK Parliament heard that the gleaming facility would one day produce 20 million plants annually. It was the latest opening for Infarm, a European vertical farming company that had raised over $600 million in venture capital funding, promising a future where vegetables are grown in high-tech warehouses stacked with LED lights rather than in open fields or greenhouses.

But now the future of the Bedford farm looks less than gleaming. On November 29, Infarm’s founders emailed its workforce to announce they were laying off “around 500 employees”—more than half of the workforce. The email detailed the firm’s plans to downsize its operations in the UK, France, and the Netherlands, and concentrate on countries where it had stronger links to retailers and a higher chance of eventually

The Mystery of Nevada’s Ancient Reptilian Boneyard

Berlin, Nevada, is a treasure chest for paleontologists. Just down the road from now-abandoned gold and silver mines, a rockbound collection of bones hints at an even richer past. The Berlin-Ichthyosaur State Park is teeming with dozens of fossils of ancient marine reptiles. That bone bed is so abundant and weird that researchers have been scratching their heads over it for decades.

“There are sites with way more dense occurrences of ichthyosaur skeletons, including places in Chile and Germany,” says Nick Pyenson, curator of fossil marine mammals at the Smithsonian National Museum of Natural History. “But this place, Berlin-Ichthyosaur in eastern Nevada, has really escaped explanation for a long time.” In one particular quarry, at least seven individuals from the genus Shonisaurus—a bloated, bus-sized dolphin with four limb-like flippers—lay essentially stacked atop one another.

Previous hypotheses largely focused on physical or environmental reasons for the cluster of fossils. One

How to Use Google Health Connect

Just about every major health and fitness category is covered, including activity, sleep, nutrition, body measurements, and vital statistics like blood pressure and heart rate. Users get full control over which categories of data are pooled and which aren’t, and everything is stored locally on their devices (rather than in the cloud) and encrypted for additional security.

Using Google Health Connect

Apps can be set to take priority over others.

Get the beta Health Connect app installed on your Android phone, open it up, and you can start deciding which of your fitness and well-being apps are allowed to interface with it. Health Connect isn’t an app in the traditional sense, and it won’t appear in the Android app drawer: You can open it from its Play Store page, from Apps in Settings, or from the Quick Settings panel.

Bio-Based Plastics Aim to Capture Carbon. But at What Cost?

It’s the year 2050, and humanity has made huge progress in decarbonizing. That’s thanks in large part to the negligible price of solar and wind power, which was cratering even back in 2022. Yet the fossil fuel industry hasn’t just doubled down on making plastics from oil and gas—instead, as the World Economic Forum warned would happen, it has tripled production from 2016 levels. In 2050, humans are churning out trillions of pounds of plastic a year, and in the process emitting the greenhouse gas equivalent of over 600 coal-fired power plants. Three decades from now, we’ve stopped using so much oil and gas as fuel, yet way more of them as plastic.

Back here in 2022, people are trying to head off that nightmare scenario with a much-hyped concept called “bio-based plastics.” The backbones of traditional plastics are chains of carbon derived from fossil fuels. Bioplastics instead use

A New NASA Satellite Will Map Earth’s Rising Seas

SWOT could turn out to be a major improvement over measurements by previous satellites. “Instead of a ‘pencil beam’ moving along the Earth’s surface from a satellite, it’s a wide swath. It’ll provide a lot more information, a lot more spatial resolution, and hopefully better coverage up close to the coasts,” says Steve Nerem, a University of Colorado scientist who uses satellite data to study sea-level rise and is not involved with SWOT. And KaRIn’s swath-mapping technology is a brand-new technique, he says. “It’s never been tested from orbit before, so it’s kind of an experiment. We’re looking forward to the data.”

SWOT has other instruments in its toolkit too, including a radar altimeter to fill in the gaps between the swaths of data KaRIn collects, a microwave radiometer to measure the amount of water vapor between SWOT and the Earth’s surface, and an array of mirrors for laser-tracking measurements
