The idea of a human-made device that can process solar energy to make usable fuels has been tantalizing researchers since the 1970s. There being no such thing as a free lunch, it is not so easy to engineer a device that mimics photosynthesis, which Mother Nature perfected a long time ago. Nevertheless, researchers at the Department of Energy’s Lawrence Berkeley Lab in California appear to have solved an important piece of the “artificial leaf” challenge.

Solar Energy & The Artificial Leaf Of The Future

The concept of the artificial leaf first crossed the CleanTechnica radar in the form of a card-sized photoelectrochemical cell, back in 2011. Instead of converting sunlight into electricity, the cell acts as a catalyst that deploys solar energy to break water into oxygen and hydrogen.

Swiss tech company ABB has unveiled a new EV charging station that can rapidly power four electric vehicles at once — which could help make annoying wait times at stations a thing of the past.

The challenge: It typically takes less than five minutes to fill up a car’s tank at a gas station, and gas stations are everywhere in the U.S.

Japan’s growing lost earbuds problem meets its end with a vacuum cleaner-like gadger collaboration between Panasonic and JR East.

After a successful launch of NASA’s James Webb Space Telescope Dec. 25, and completion of two mid-course correction maneuvers, the Webb team has analyzed its initial trajectory and determined the observatory should have enough propellant to allow support of science operations in orbit for significantly more than a 10-year science lifetime. (The minimum baseline for the mission is five years.)

The analysis shows that less propellant than originally planned for is needed to correct Webb’s trajectory toward its final orbit around the second Lagrange point known as L2, a point of gravitational balance on the far side of Earth away from the Sun. Consequently, Webb will have much more than the baseline estimate of propellant – though many factors could ultimately affect Webb’s duration of operation.

Webb has rocket propellant onboard not only for midcourse correction and insertion into orbit around L2, but also for necessary functions during the life of the mission, including “station keeping” maneuvers – small thruster burns to adjust Webb’s orbit — as well as what’s known as momentum management, which maintains Webb’s orientation in space.

The anterior insular cortex requires more understanding in its role for human cognition and consciousness. But the next time you notice a cyclist who came out of nowhere or a dog that’s about to round the corner, you can thank your anterior insular cortex for it.

INVERSE is counting down the 20 science discoveries that made us say “WTF” in 2021. This is #2. Read the original story here.

An international scientific group with outstanding Valencian participation has managed to measure for the first time oscillations in the brightness of a neutron star – magnetar – during its most violent moments. In just a tenth of a second, the magnetar released energy equivalent to that produced by the Sun in 100,000 years. The observation has been carried out automatically, without human intervention, thanks to the Artificial Intelligence of a system developed at the Image Processing Laboratory (IPL) of the University of Valencia.

Among the neutron stars, objects that can contain half a million times the mass of the Earth in a diameter of about twenty kilometers, stands out a small group with the most intense magnetic field known: magnetars. These objects, of which only thirty are known, suffer violent eruptions that are still little known due to their unexpected nature and their duration of barely tenths of a second. Detecting them is a challenge for science and technology.
