O,.o circa 2019.
The latest from NASA’s X-plane series could make Concorde-style supersonic commercial flights a reality again without the deafening sonic boom noise.

A NASA study has recently concluded that the “Cannae Drive,” a disruptive new method of space propulsion, can produce small amounts of thrust without the use of propellant, in apparent discordance with Newton’s third law. According to its inventor, the device can harness microwave radiation inside a resonator, turning electricity into a net thrust. If further verified and perfected, the advance could revolutionize the space industry, dramatically cutting costs for both missions in deep space and satellites in Earth orbit.
The basic principle behind space propulsion is very simple: for every action, there is an equal and opposite reaction. Use a rocket engine to throw mass one way, get propelled the other way. And according to the law of conservation of momentum, the more mass you throw behind you and the faster you throw it, the stronger your forward thrust will be.

Since we last explored the Brown Mountain Lights (March/April 1995), new scientific research teams were formed, the Burke County Tourism Authority offered sold-out symposia, the lights were featured in a National Geographic show and more.
Erik Rintamaki was searching for rocks on a Michigan beach last summer when he made what he calls a “mind blowing” discovery. Resting among the thousands of pebbles covering the Lake Superior beach, Rintamaki saw a glowing rock.
Farms that grow metal-rich plants are cropping up around the world and promise a greener, less destructive alternative to mining for rare minerals.

Smartwatches and other battery-powered electronics would be even smarter if they could run AI algorithms. But efforts to build AI-capable chips for mobile devices have so far hit a wall—the so-called “memory wall” that separates data processing and memory chips that must work together to meet the massive and continually growing computational demands imposed by AI.
“Transactions between processors and memory can consume 95 percent of the energy needed to do machine learning and AI, and that severely limits battery life,” said computer scientist Subhasish Mitra, senior author of a new study published in Nature Electronics.
Now, a team that includes Stanford computer scientist Mary Wootters and electrical engineer H.-S. Philip Wong has designed a system that can run AI tasks faster, and with less energy, by harnessing eight hybrid chips, each with its own data processor built right next to its own memory storage.
Very interesting.
Patients with severe COVID-19 disease have significantly shorter telomeres, according to a study conducted by researchers at the Spanish National Cancer Research Centre (CNIO) in collaboration with the COVID-IFEMA Field Hospital, published in the journal Aging. The study, led by Maria A. Blasco and whose first authors are Raúl Sánchez and Ana Guío-Carrión, postulates that telomere shortening as a consequence of the viral infection impedes tissue regeneration and that this is why a significant number of patients suffer prolonged sequelae.
Blasco was already developing a therapy to regenerate lung tissue in pulmonary fibrosis patients; she now believes that this treatment — which should still take at least a year and a half to become available — could also help those who have lung lesions remaining after overcoming COVID-19.

Believe it or not, Bigfoot has been reportedly spotted in Colorado more than 100 times in recent years, including one notable daylight spotting that occurred in Summit County, Colorado.
During this summer 2019 spotting, a daytime hiker was taking a break near an old log cabin in the area of Mayflower Gulch near Frisco when he spotted something odd at about 11000 feet of elevation. He reports seeing a large bipedal creature attempting and failing to climb a 20-foot high snow wall. After the failed attempt at scaling the barrier, the creature moved on and out-of-sight.
