Anyone who knows me (photo above in black), knows that the condition of my skin is something I take very seriously, yet I am not always happy with. I am very fair-skinned and unfortunately, sun care wasn’t something I practiced until I was in my mid twenties. And embarrassingly I will admit…
To better understand certain problems involving rockets and propulsion it is necessary to use some mathematical ideas from trigonometry, the study of triangles. …

NPR’s Planet Money decided to sell some T-shirts. But they didn’t just buy them they tracked the production from growing the cotton to delivering them to your door.

Human embryo at 7 weeks gestation, measuring approximately 14 mm (crown to rump). the fingers and face are developing and growing rapidly but are still forming their shape. It is possible to clearly see the formation of the skull, which begins to close, which will form the fontanelle (“soft spots”) that subsequently shut as children grow, creating a suture in the skull. This openness facilitates at birth in normal delivery, and allows the growth of the child’s brain.

A new species of crustacean has been found off the coast of California by an international team of researchers. This well-armed, other-worldly creature has been named Liropus minusculus, which refers to its minuscule size - the males only stretch to about 3.3 mm, while the females are even smaller, at 2.1 mm long.

They’re pretty much everywhere.
In the harshest environments, even on highways some extremophile mosses, lichens and algae can survive. Most of them aren’t very welcome on the walls of our cities. Since they’re easier to remove than graffiti many house owners remove them first.
But did you know these, so called, cryptogamic covers are huge CO2 and Nitrogen storages?
Chemists, biologists and geologists worked together to find out recently that these plants store approximately 14 billion tons of carbon dioxide and fix approximately 50 million tons of nitrogen per year!
This order wasn’t expected at all and is about the number of carbon dioxide that is burned each year from forrests and other biomass.

Birth of New Species Requires Very Few Genetic Changes
Only a few genetic changes are needed to spur the evolution of new species — even if the original populations are still in contact and exchanging genes. Once started, however, evolutionary divergence evolves rapidly, ultimately leading to fully genetically isolated species, report scientists from the Univ. of Chicago in Cell Reports.
“Speciation is one of the most fundamental evolutionary processes, but there are still aspects that we do not fully understand, such as how the genome changes as one species splits into two,” says Marcus Kronforst, Neubauer Family assistant professor of ecology and evolution, and lead author of the study.
