Developed by researchers in Saudi Arabia, the novel approach considers both the power yield and the solar module time to failure (TTF), among other factors. According to its creators, the model can be applied to all kinds of module and cell technologies.
It seems some people are using deepfake to misinform people.
Facebook and YouTube said Wednesday that they removed uploads of a deepfake video of Ukrainian President Volodymyr Zelensky that purported to show him yielding to Russia.
For the second time ever, SpaceX has used Starbase’s ‘Mechazilla’ tower and arms to stack a Starship upper stage on top of a Super Heavy booster.
This time around, though, SpaceX clearly learned a great deal from its second February 9th Starship stack and was able to complete the stacking process several times faster on March 15th. During the second attempt, depending on how one measures it, it took SpaceX around three and a half hours from the start of the lift to Starship fully resting on Super Heavy. With Stack #3, however, SpaceX was able to lift, translate, lower, and attach Starship to Super Heavy in just over an hour.
Oddly, SpaceX managed that feat without a claw-like device meant to grab and stabilize Super Heavy during stacking operations. For Stack #2, all three arms were fully in play. First, a pair of ‘chopsticks’ – giant arms meant to grab, lift, and even recover Starships and boosters – grabbed Ship 20, lifted it close to 100 meters (~300 ft) above the ground, rotated it over top of Super Heavy, and briefly paused. A third arm – known as the ship quick-disconnect or umbilical arm – swung in and extended its ‘claw’ to grab onto hardpoints located near the top of Super Heavy. Once the booster was secured, the ‘chopsticks’ slowly lowered Ship 20 onto Booster 4’s interstage and six clamps joined the two stages together.
Bacteria might be the solution to all of our space breathing issues. According to Mashable, scientists may use cyanobacteria to figure out how humans might quickly acquire oxygen in space.
Cyanobacteria convert carbon dioxide into oxygen. Cyanobacteria are found in extremely difficult settings on Earth, thus it is predicted that they would be able to live on Mars.
Some scientists have proposed transporting the bacterium to Mars to test whether it can produce oxygen for future people who could end up there. Experiments have previously demonstrated that cyanobacteria can flourish in a Martian environment.

Einstein’s General Theory of Relativity predicted that massive objects will bend light as it travels past them. That means that any light passing very close to an invisible black hole—but not close enough to end up inside it—will be bent in a similar way to light passing through a lens. This is called gravitational lensing, and can be spotted when a foreground object aligns with a background object, bending its light. The method has already been used to study everything from clusters of galaxies to planets around other stars.
The authors of this new research combined two types of gravitational lensing observations in their search for black holes. It started with them spotting light from a distant star suddenly magnify, briefly making it appear brighter before going back to normal. They could not see any foreground object that was causing the magnification via the process of gravitational lensing, though. That suggested the object might be a lone black hole, something which had never been seen before. The problem was that it could also just have been a faint star.
Figuring out if it was a black hole or a faint star required a lot of work, and that’s where the second type of gravitational lensing observations came in. The authors repeatedly took images with Hubble for six years, measuring how far the star appeared to move as its light was deflected.

For all his genius, he had his tendency to be stuck in his ways — whether black holes, quantum mechanics, or flip-flopping on gravitational waves.
