A spectacular superconductor claim is making news. Here ’s why experts are doubtful
This week, social media has been aflutter over a claim for a new superconductor that works not only well above room temperatures, but also at ambient pressure. If true, the discovery would be one of the biggest ever in condensed matter physics and could usher in all sorts of technological marvels, such as levitating vehicles and perfectly efficient electrical grids. However,

Crops grown without sunlight could help feed astronauts bound for Mars
Riverside, California—
For the first astronauts to visit Mars, what to eat on their 3-year mission will be one of the most critical questions. It’s not just a matter of taste. According to one recent estimate, a crew of six would require an estimated 10,000 kilograms of food for the trip. NASA—which plans to send people to Mars within 2 decades—could stuff a spacecraft with prepackaged meals and launch additional supplies to the Red Planet in advance for the voyage home. But even that wouldn’t completely solve the problem.
Micronutrients, including many vitamins, break down over months and will need to...

Nearly All of Earth ’ s Ecological Vital Signs Are In The ‘ Danger Zone ’ Scientists Warn
Earth has pushed past seven out of eight scientifically established safety limits and into “the danger zone,” not just for an overheating planet that’s losing its natural areas, but for well-being of people living on it, according to a new study.
The study looks not just at guardrails for the planetary ecosystem but for the first time it includes measures of “justice,” which is mostly about preventing harm for countries, ethnicities and genders.
The study by the international scientist group Earth Commission published in Wednesday’s journal Nature looks at climate, air pollution, phospho...

Dredged lake sediment could nourish new crops
Every year, farmers fertilize their crops with nitrogen and phosphorus to ensure a good harvest. And every year some of that fertilizer inevitably makes its way into ponds and lakes, where it can trigger ecosystem-wrecking algal blooms. According to a new study published last month in
Science of the Total Environment
, though, there may be a relatively simple way to close the loop on this leaky system:
using the nutrient-rich lake sediments as fertilizer

“We’d be wise as a society to recycle these nutrients,” says University of Illinois Urbana-Champaign soil scientist Andrew Margenot, who ...

How to Harness Mega Seaweed Blobs For a More Sustainable Future
On Oct. 7, 1492, Christopher Columbus, aboard his ship the Santa María, had been at a complete standstill for 21 days, trapped in a very strange sea which he would later name the Sargasso Sea—sargazo in Spanish meaning “gulfweed.” Today, the Sargasso Sea—an elliptical expanse in the southwestern Atlantic at the center of which lies Bermuda—is six times the size of France, and is the only sea in the world with no shoreline. There was great anxiety among Columbus’s sailors as their already heavily rationed food supplies dwindled the longer they remained stuck. Not the slightest wind...

The Water Crisis No One In America Is Fixing
On Feb. 3, 2022, a train loaded with toxic chemicals derailed in East Palestine, Ohio, igniting a fire and forcing the controlled release and burn of vinyl chloride, a known cancer-causing compound, to avert a disastrous explosion. The environmental catastrophe killed thousands of fish in nearby streams and has triggered growing concerns over the impact on residents’ health and on the village’s surface, ground, and well water.
East Palestine joins a long list of other places in the United States facing major threats to clean water. In October 2022, a campaign called “Imagine a Day Without Water” ask...
