Mermaids Of Earth

One man's website that is devoted to mermaids - in stories, paintings, graphic arts, movies, sculptures and other forms of art.

A teaspoon of soil from the Amazon contains as many as 1,800 microscopic life forms, of which 400 are fungi.

NASA’s Double Asteroid Redirection Test (DART), the first full-scale demonstration of an asteroid deflection technology for planetary defense, is set for 2022. The DART spacecraft will execute a kinetic impact, deliberately crashing into an asteroid to change its motion in space.

Rt Covid-19

These are up-to-date values for Rt, a key measure of how fast the virus is growing. It’s the average number of people who become infected by an infectious person. If Rt is above 1.0, the virus will spread quickly. When Rt is below 1.0, the virus will stop spreading.

"With about 200,000 people flowing into and out of jails every week, there are great risks not only for the detained, but also for jail workers and surrounding communities."

Maybe you'll read this and feel better about things. Maybe you'll fee worse. You'll definitely feel better equipped to wade through the less informed novel coronavirus/COVID-19 coverage out there.

"There are few people I’ve learned more from over the years–especially about viruses–than Peter Piot." - Bill Gates

Joseph G. Allen is an assistant professor of exposure and assessment science and director of the Healthy Buildings Program at Harvard University’s T.H. Chan School of Public Health.

He explains the reality of transferring the virus via surfaces.

Fortunately, [EHS] is not as dangerous as it sounds.     But it is a real condition, and researchers are finally beginning to seriously investigate the rare and little-understood sleep disorder.

"Of the three infants [of mothers with covid-19, for who consent to be diagnostically tested was provided, none tested positive for the virus."

I'm trying to be cautious with the headline, but this does come from a peer reviewed study.

Exponential growth in numerical series and graphs is grossly underestimated in an intuitive extrapolation task. Subjects’ extrapolations are well described by a model with two parameters only: one for underestimation of the nonlinear growth, the other for linear compensation. The size of the effect is considerable; it is not unusual that two-thirds of the subjects produce estimates below 10% of the normative value. The effect increases with the exponent of the stimulus series, and with addition of a constant to the stimulus series. Neither special instructions about the nature of exponential growth nor daily experience with growth processes enhanced the extrapolations.

Oxford's 'Our World in Data' is a great place to find data, visualizations, and analysis of global issues and trends. It's uniquely suited to explaining and tracking COVID-19. Founder and Director @MaxCRoser is also a great follow on Twitter.

You won't have to read far to find something you didn't know, or at least something presented in a way that expands your understanding. For example, this is the first time I've seen a full list of symptoms organized by their commonality.

If someone in your life is struggling to grasp the big picture, send them here. And if you or someone in your life is feeling ill, call a doctor.

Researchers say it is the first time such skill has been shown outside of humans and great apes

Very cute way to get useful info to kids.
