Chrome 148 Will Start 'Lazy Loading' Video and Audio to Improve Performance

1 month ago
"Google has announced that it's currently testing a new feature for Chrome 148 that could speed up day-to-day browsing," reports PC World: [T]he browser can intelligently postpone the loading of certain elements. Why load all images at the start when it can instead load images as you get close to them while scrolling? Chrome and Chromium-based browsers have had built-in lazy loading support for images and iframes since 2019, but this feature would make browsers capable of lazy loading video and audio elements, too. Note, however, that this won't benefit YouTube video embeds — those are already lazy loadable since they're embedded using iframes. Actual video and audio elements are rarer but not uncommon. In addition to Chrome, lazy loading of video and audio elements is also expected to be added to other Chromium-based browsers, including Microsoft Edge and Vivaldi.

Scientists Engineered a Plant To Produce 5 Different Psychedelics At Once

1 month ago
Plants, toads, and mushrooms "can all produce psychedelic substances," writes ScienceAlert. "And now their powers have been combined in one plant." [S]cientists have taken the genes these organisms use to make five natural psychedelics and introduced them into a tobacco plant ( Nicotiana benthamiana), which then produced all five compounds simultaneously. As interest grows in psychedelics as potential treatments for illnesses such as depression, anxiety, and PTSD, the newly developed system could offer scientists a new way to produce these compounds for research purposes... [P]rogress in this field remains limited, in part due to regulatory restrictions, underscoring the need for more research. This creates practical challenges for scientists. "Traditionally, the supply of psychedelics relies on natural producers, mainly plants, fungi, and the Sonoran Desert toad," the researchers write. "Harvesting these organisms for their psychoactive compounds raises ecological and ethical concerns, being increasingly threatened by habitat loss and overexploitation..." [T]he team carefully monitored the plant's production of five psychedelic tryptamines: DMT originally from plants; psilocin and psilocybin from mushrooms; and bufotenin and 5-MeO-DMT from toads. The modified tobacco plants were found to produce all five compounds simultaneously. The article points out that the researchers "also took it a step further." By tweaking the enzymes they were able to "produce modified versions of the compounds that do not naturally occur in plants, and which may also have therapeutic value."
