The synthetic (or man-made) elements are the ones with silly-sounding names, found along the bottom of the periodic table — Einsteinium and Nobelium, Livermorium and Mendelevium, and more. Unlike the rest of the elements, you won't find them just hanging out in nature. They have to be created in a laboratory, and they only exist for a limited amount of time — some no more than milliseconds. Though new ones have been discovered/created as recently as 2010, the 1950s and 60s were sort of a heyday of synthetic elements, with different laboratories locked in a race to find the niftiest new things first.
During that time, researchers at Lawrence Berkeley National Lab made a film strip reenacting their own 1955 discovery of the element Mendelevium. The film lay forgotten in storage for 60 years until it was recently uncovered and restored by retired physicist Claude Lyneis. Originally just a silent sequence showing real Mendelevium discoverers Al Ghiorso, Bernard Harvey, Gregory Choppin, and Stanley Thompson demonstrating how they'd found the 101st element, the film has been updated with narration and sound effects and is a pretty cool explanation of where synthetic elements come from.
Researchers at UC Riverside and Centro de Investigación Científica y de Educación Superior de Ensenada have published a paper describing their ongoing success in setting a “transparent nanocrystalline yttria-stabilized-zirconia” into patients’ skulls, which reveal the patients’ brains so that the patients’ brains can be zapped with therapeutic lasers.
One million miles from Earth, hanging in space between Earth’s gravitational pull and the sun’s, is the DSCOVR satellite and NASA’s incredible EPIC camera. Every two hours, EPIC takes a photo of Earth “to monitor ozone and aerosol levels in Earth’s atmosphere, cloud height, vegetation properties and the ultraviolet reflectivity of Earth.” The above video […]
In Botswana, conservation scientists from the University of New South Wales are painting eyes on the rear ends of cattle in an effort to deter lions from eating them. As the lions’ protected habitats shrink, they move closer to human settlements. In Botswana, the lions attack the livestock that the subsistence farmers count on. That […]
3D printers are hot, but they’re also pricey. While the prospect of cranking out everything we can dream up is enticing, cost is often one factor that keeps us from jumping onto the 3D printing train.Now, thanks to M3D, that doesn’t have to be the case. You can now get its flagship 3D printer–plus four reels of filaments–for just […]
It’s no secret that technology is changing the way we all work—but it’s also transforming the way we play. The games of today look nothing like those of 10 or even 20 years ago: these days it’s all about mobile and 3D. And now you can learn to design 3D mobile games with the Intro to Unity 3D Game […]
