James Webb Space Telescope:
The James Webb Space Telescope (JWST) has reached a critical stage in aligning its mirrors. Pictures from the process showed that everything was working much better than expected, and the telescope operators said that its operation would be able to meet or exceed the original goals.
The legs of a robot with an unusual design inspired by flying birds can work up to 300 percent more efficiently than a similar device if designed specifically. The technology could be used to make artificial limbs and exoskeletons, say researchers.
Sensors inspired by Dandelion:
Small airborne sensors like dandelion seeds can help record natural signals in a wide area. Small sensors with a design promoted by dandelion seeds can be distributed in the air to help track important indicators of climate change and global warming. As the climate problem continues to intensify, tracking changes in temperature, humidity, and other environmental features is helpful. But to do so effectively requires that you disperse sensors throughout your surroundings, which may take time.
IT Army of Ukraine:
The Ukrainian government-sponsored terrorist organization has cracked down on websites of Russian government departments and national banks.Thousands of amateur hackers from around the world have joined a Ukrainian group committed to undermining the Russian government and its financial websites as a result of the country's invasion, according to Ukrainian government statements, evidence of a Russian website crash and instant messaging groups. seen by New Scientist. Ukraine's IT Army was conceived by Mykhailo Fedorov, Ukraine's deputy prime minister.
Rise of the molecular machines:
Atomic machines are used to sew together a molecule of new material by molecule, which can open flood gates in all forms of inventions. Simple molecular machines have been around for almost two decades. Early examples include molecular wheels that can travel through an axle, creating a piston-like structure. Three pioneers in this field - Fraser Stoddart from Northwestern University in Illinois, Ben Feringa from the University of Groningen in the Netherlands and Jean-Pierre Sauvage from the University of Strasbourg, France - were honored with the 2016 Nobel Peace Prize. Many useful devices are now being developed and tested. A few years ago, the James Tour at the University of Rice in Houston, Texas, and his colleagues developed a molecular machine that could pierce the cell membrane. This allows it to open holes where drugs can be delivered. Such equipment can be built on top to build even more sophisticated equipment. Great potential: after all living things use biomolecular machinery to perform many useful functions. Ribosomes, for example, are biomolecular machinery that binds proteins. They add cells called amino acids together in sequence to form a huge network of amazing things, from keratin in fingernails to antibodies that attack our immune system.
