Scientists Have Invented Light-Up OLED Tattoos

An anonymous reader quotes a report from Gizmodo: Tattoos are usually considered a form of personal expression, but a team of researchers in Europe have created what they’re calling the world’s first light-emitting tattoo based on OLED screen technology that, besides presumably looking kind of cool, could also serve as a visible warning about potential health concerns. In a recently published…

Quantum Computer Solves Decades-Old Problem Three Million Times Faster Than a Classical Computer

ZDNet reports: Scientists from quantum computing company D-Wave have demonstrated that, using a method called quantum annealing, they could simulate some materials up to three million times faster than it would take with corresponding classical methods. Together with researchers from Google, the scientists set out to measure the speed of simulation in one of D-Wave’s quantum annealing processors, and found that…

Evidence for white dwarfs consuming Earth-like worlds

For the first time, astronomers have detected the vaporized remains of the crusts of long-dead Earth-like and Mars-like planets in the atmospheres of white dwarf stars. Source: https://earthsky.org/space/vaporized-earth-like-mars-like-crusts-white-dwarf-stars…

Apple Has Bought Over 100 Companies Over the Past Six Years, Tim Cook Tells Investors

Apple Chief Executive Officer Tim Cook fielded questions on mergers and acquisitions, the impact of Covid-19, and the company’s supply chain during a virtual shareholder meeting on Tuesday. From a report: Narrating a slide show, Cook summarized many of the company’s new products and initiatives announced over the past year. He spoke about the latest iPhones and the growing potential of…

Magnetic effect without a magnet

Electric current is deflected by a magnetic field—in conducting materials, this leads to the so-called Hall effect. This effect is often used to measure magnetic fields. A surprising discovery has now been made at TU Wien, in collaboration with scientists from the Paul Scherrer Institute (Switzerland), McMater University (Canada), and Rice University (U.S.): an exotic metal made of cerium, bismuth and…

Repotting Plants Without Killing Them

Repotting plants can seem like an intimidating or messy task, but with the right information, and a little practice, it is a rather fun activity for you and your plants. In this article: What Does Repotting Plants Mean? Why Is It Important to Repot Plants? What Are the Signs That Plants Need Repotting? When Is…Continue Reading

A unique prototype of microbial life designed on actual Martian material

Experimental microbially assisted chemolithotrophy provides an opportunity to trace the putative bioalteration processes of the Martian crust. A study on the Noachian Martian breccia Northwest Africa (NWA) 7034, composed of ancient (ca. 4.5 Gyr old) crustal materials from Mars has delivered a unique prototype of microbial life experimentally designed on actual Martian material. As the researchers show in the current issue…

Biden To Order Review of US Reliance on Overseas Supply Chains For Semiconductors, Rare Earths

President Joe Biden will direct his administration to conduct a review of key U.S. supply chains including semiconductors, high-capacity batteries, medical supplies and rare earth metals. From a report: The assessment, which will be led by members of both Biden’s economic and national security teams, will analyze the “resiliency and capacity of the American manufacturing supply chains and defense industrial base…
