A collaboration between the automaker and the utility will test-drive using bidirectional charging to power homes during blackouts.
The humble lamp can come in many different forms, but nearly all of them feature a singular bulb that is uninspired and only responds to a light switch or potentially an app. YouTuber Tom Ouwerkerk, on the other hand, has designed a creative light accessory that is entirely 3D-printed and includes an intelligent central bulb that “magically” levitates above the base, defying gravity.
For the base of the lamp, Ouwerkerk printed a simple ring with a cutout on its side for plugging in a DC barrel jack. From there, he added an Arduino Nano Every that is responsible for controlling a strip of four WS2812B RGB LEDs and sensing if the bulb has been placed into its off position. When the bulb isn’t resting on top of the base, its top magnet gets attracted to the other magnet, which faces down from the top of the lamp and helps pull it upwards for the floating effect.

An analysis of radioactive chemicals in ice cores indicates one of the most powerful solar storms ever hit Earth around 7,176 B.C.
(Inside Science) — For a few nights more than 9,000 years ago, at a time when many of our ancestors were wearing animal skins, the northern skies would have been bright with flickering lights.
Telltale chemical isotopes in ancient ice cores suggest one of the most massive solar storms ever took place around 7,176 B.C., and it would have been noticed.

Fluicell, a bioprinting firm based in Sweden, has launched its new high-precision 3D printer, the Biopixlar AER.
Intended as a successor to the original Biopixlar, the device is Fluicell’s second single-cell 3D bioprinting system. The company has designed its latest machine to be as compact and accessible as possible, and claims that it’s the world’s first microfluidic bioprinter that fits inside a standard flow hood or biosafety cabinet. This enables users to easily integrate it with other in vitro and 3D cell culture technologies.
Victoire Viannay, CEO of Fluicell, said, “With Biopixlar AER, we have reached a new important milestone and we can now offer a pioneering product, fully tailored to meet current and future needs in the rapidly accelerating life science and research sector.”

MercadoLibre, one of the most important e-commerce companies in Latin America, confirmed unauthorized access to a part of its source code, in addition to confirming that the attackers managed to access the personal records of some 300,000 users. The company has not confirmed that its IT infrastructure was affected during the incident.
The Argentine firm confirmed the compromise of its systems after hackers from the Latin American group Lapsus$ threatened to expose confidential information from MercadoLibre and other e-commerce platforms. Faced with this threat, MercadoLibre enabled all its security and containment protocols, so it recommended that users of the platform change their passwords and monitor their account statements to prevent any attempt at malicious activity.
