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.
Depending on an EV’s battery and the type of EV charging station, it can take anywhere from 45 minutes to several hours to fully charge the car, and because charging stations are far less common than gas stations, drivers regularly have to wait for ports to open up.
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.

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.
An international scientific team with outstanding participation from the University of Valencia has published recently in the journal Nature the study of the eruption of a magnetar in detail: they have managed to measure oscillations – pulses – in the brightness of the magnetar during its most violent moments. These episodes are a crucial component in understanding giant magnetar eruptions. It is a question long debated during the past 20 years that today has an answer, if there are high-frequency oscillations in the magnetars.
From preventing blindness to helping children read to forecasting floods, AI has come a long way from the specialised labs where it emerged, here’s how it is reshaping lives in India.
Astronomers have captured a breathtaking radio wave image, showing our closest radio active black hole spewing out massive jets of plasma that span more than 16 times the size of the full moon in our sky.
The supermassive black hole in question is located in the center of the galaxy Centaurus A around 12 million light-years away.
The black hole has a jaw-dropping mass of around 55 million Suns but isn’t visible in the image. It would be located within the small empty patch in the center of the two butterfly wing-like lobes.
While working with helium nanodroplets, scientists at the Department of Ion Physics and Applied Physics led by Fabio Zappa and Paul Scheier have come across a surprising phenomenon: When the ultracold droplets hit a hard surface, they behave like drops of water. Ions with which they were previously doped thus remain protected on impact and are not neutralized.
At the Department of Ion Physics and Applied Physics, Paul Scheier’s research group has been using helium nanodroplets to study ions with methods of mass spectrometry for around 15 years. Using a supersonic nozzle, tiny, superfluid helium nanodroplets can be produced with temperatures of less than one degree Kelvin. They can very effectively be doped with atoms and molecules. In the case of ionized droplets, the particles of interest are attached to the charges, which are then measured in the mass spectrometer. During their experiments, the scientists have now stumbled upon an interesting phenomenon that has fundamentally changed their work. “For us, this was a gamechanger,” says Fabio Zappa from the nano-bio-physics team. “Everything at our lab is now done with this newly discovered method.” The researchers have now published the results of their studies in Physical Review Letters.
