Scientists have discovered a 300-million-year-old lizard in Canada that proves the first instance of animal #parentalcare in a bombshell scientific revelation.

“There’s no delete button online,” she says. “Just when you think you’re doing better, something can pop up and trigger your emotions. It is truly like PTSD. It isn’t something you just move on from.”

While production methods are improving, large scale, environmentally sound synthesis of graphene is not yet in full swing. According to the #Graphene Flagship, a European project dedicated to graphene, several products should be commercially available in another 10 or 15 years. Much remains to be seen.

A team of researchers from the University of Colorado Boulder, the Colorado School of Public Health and the University of Pennsylvania has found evidence that suggests higher CO2 levels in the future may adversely impact the cognitive abilities of students in classrooms.

The Stone-Age birch pitch ‘chewing gum’ yielded enough information to determine the source’s sex, what she had last eaten and the germs in her mouth. It also told them she probably had dark hair, dark skin and blue eyes.
So, I just discovered this website on #antennas: http://www.antenna-theory.com/
It not only has sections on different types of antennas but also introduces one to the preliminaries required to understand the subject (such as impedance matching on transmission lines with the help of Smith chart).

#TIL Pluto was discovered using a machine called a blink comparator. This machine dates back to 1904 and — like many things — has been superseded by modern technology. In 1930, scientists knew there was something pulling the orbits of the planets but they didn’t know where it was.
The blink comparator helps you find something that moves by showing you two photographic plates in quick succession. Anything in the same spot on both plates appears stationary. Anything moving in the frame will stand out as it appears to jump from one spot to another.

We are finally in the graphene age!
Our universe is governed by four fundamental forces. At least that's what physicists have long thought.
Now, however, new research suggests that there's a fifth force, a discovery that could upend much of modern physics.

Free books, read online. Many authors and genres.
Don't know how they do it, get away with it, but...
Found a website listing many, many books, including the one with the cover below, by Charles Bukowski.
https://bookfrom.net/charles-bukowski/
You CAN read the whole book online it seems, and they have many other authors. From trashy breathless romance novels to works we can be grateful to get access to. Android app for mobile if needed.
Rather cool. Librarian in me wants to spread the word. Hush, hush. DMCA is a thing.
They do have many of Cory Doctorow's books too, excellent sci-fi writer. https://bookfrom.net/cory-doctorow/
