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.
University of Zurich researchers used transcranial magnetic stimulation, a noninvasive method of inhibiting activity in parts of the brain, to “turn off” people’s ability to control their impulses. They focused on the temporoparietal junction, an area of the brain thought to play an important role in moral decisions, empathy, and other social interactions. They hope […]

The Atmos R2 may be bigger than the brand’s previously-released vapes, but we argue that in this case it’s definitely a good thing. A bigger heating chamber means more room for packing it full. And the bigger battery means longer, more fulfilling vape sessions. In fact, you can use the Atmos R2 for up to about 25 […]
These days, there is huge demand for ethical hackers. Companies pay these professionals to identify and remedy security holes in their networks before malicious hackers find and exploit them. What’s great about this is that if you love hacking or think you may love hacking, you can do it for a living and not as […]
