Atmospheric winds have surprising impact on ocean weather

U.S. National Science Foundation-supported researchers published a new paper that explains how atmospheric wind affects eddies, an ocean weather phenomena of spinning ocean currents. “Our theory and findings provide a roadmap for incorporating interactions between winds and ocean eddies into operational and long-term forecasting,” said Hussein Aluie, a co-author on the paper and professor at the University of Rochester.

“Accurate ocean forecasts are essential for navigation and shipping, fisheries management, disaster response, coastal management and climate prediction,” Aluie said. These economic sectors rely on accurate forecasts to plan for potentially dangerous conditions.

Aluie and a team of researchers used satellite imagery and climate models to discover that not only do atmospheric winds dampen eddies, like previously thought, but they can also energize them. Prevailing winds that move longitudinally across the globe, like westerlies and trade winds, slow eddies when they move in the opposite direction but energize them if they spin the same way.

Between the eddies are ocean weather phenomenon called strain, which account for about half of the ocean’s kinetic energy. The team found that strain is also dampened or energized by wind-like eddies.

“The new energy pathways between the atmosphere and the ocean that we discovered can help design better ocean observation systems and improve climate models,” said Shikhar Rai, the study’s first author and a doctoral student at the University of Rochester,

This spa’s water is heated by bitcoin mining

At first glance, the Bathhouse spa in Brooklyn looks not so different from other high-end spas. What sets it apart is out of sight: a closet full of cryptocurrency-­mining computers that not only generate bitcoins but also heat the spa’s pools, marble hammams, and showers. 

When cofounder Jason Goodman opened Bathhouse’s first location in Williamsburg in 2019, he used conventional pool heaters. But after diving deep into the world of bitcoin, he realized he could fit cryptocurrency mining seamlessly into his business. That’s because the process, where special computers (called miners) make trillions of guesses per second to try to land on the string of numbers that will earn a bitcoin, consumes tremendous amounts of electricity—which in turn produces plenty of heat that usually goes to waste. 

 “I thought, ‘That’s interesting—we need heat,’” Goodman says of Bathhouse. Mining facilities typically use fans or water

How a 1980s toy robot arm inspired modern robotics

As a child of an electronic engineer, I spent a lot of time in our local Radio Shack as a kid. While my dad was locating capacitors and resistors, I was in the toy section. It was there, in 1984, that I discovered the best toy of my childhood: the Armatron robotic arm.

Described as a “robot-like arm to aid young masterminds in scientific and laboratory experiments,” it was the rare toy that lived up to the hype printed on the front of the box. This was a legit robotic arm. You could rotate the arm to spin around its base, tilt it up and down, bend it at the “elbow” joint, rotate the “wrist,” and open and close the bright-­orange articulated hand in elegant chords of
