Banded iron rocks, formed before oxygen saturated the atmosphere but after photosynthetic bacteria started releasing oxygen into the ocean, alternate layers of different iron-containing minerals that may reflect changes in bacterial population.

Interesting look at the potential for the Samsung Galaxy S20's 108-pixel camera by testing out Xiaomi’s Mi Note 10, which uses a similar sensor. Lots of discussion of not just pixel count but pixel size, light-gathering capacity, how many camera pixels are combined to make each pixel in the final image, depth of field, etc.

Love this headline:

"Turtles the size of a car once roamed the Earth. Scientists just found their fossils."

https://www.washingtonpost.com/science/2020/02/13/giant-turtle-fossil/

"The hulking reptile was about 100 times the size of its closest living relative, the Amazon river turtle, and twice the size of the largest living turtle, the marine leatherback, the researchers estimated."

In any case, it's worth remembering: mild or severe, coronaviruses spread the same way as colds and the flu.

Wash your hands. Cough and sneeze into your elbow instead of your palm. And if you get sick, stay home if you can.

Another article mentioned the H1N1 flu, which at first appeared much more deadly than other strains because it was the severe cases that were being counted. Once researchers could go back and find the mild cases, it turned out to be about the same as the typical seasonal flu.

A decade since jumping to humans, H1N1 has essentially become just another seasonal flu.

Covid-19 is somewhere in between a cold and SARS, but as mentioned above, we're still trying to figure out where.

82% of covid-19 cases ID'ed so far are mild, basically a bad cold. Virologists are trying to determine: How many more mild cases haven't been counted? And what factors cause some cases to be mild and others lethal?

Several coronaviruses already circulate globally and just cause colds. And several cause more dangerous diseases like SARS and MERS. Covid-19 is new enough that we're still trying to figure out where it is on the scale between a cold and SARS.
