Space Artists's Concepts for Unseen Planets

Check out npr  to see the process behind designing concept art for newly discovered planets. It is fascinating!

'This artist's impression shows a best guess of what the surface of the planet 
Proxima b might look like, as it orbits the red dwarf star Proxima Centauri, the 
closest star to our solar system. Maybe Mars was the model?'

Earth's history is laid out to scale on a football field. A VERY cool timeline.

Where in the World Have New Diseases Emerged?

"What new viruses are emerging in your backyard? 

If you’re a germaphobe, make sure you’re sitting down.
Back in 1999, a woman in California cleaned up rodent droppings in her home. Two weeks later, her liver started failing. Then she started to bleed internally — a hemorrhagic fever that would kill her. Eventually doctors found a new virus in her body, which very likely came from a rat.
A few years later, a man in Arizona went to the hospital. The skin on his legs was infected and dying. Doctors had to amputate. His diagnosis? A new kind of leprosy.
Over in the Midwest, the problem has been new tick-borne diseases, some deadly. And in New England, doctors are dealing with a disease that causes Lyme-like symptoms but is caused by a different bacteria.
The pattern continues across the country and across the world. A spike in new infectious diseases is the new normal.
      Another side effect of humanity’s conquest of the natural world."

Frog Spit is a Non-Newtonian Fluid

"The researchers used high-speed photography and an instrument called a Rheometer to analyze frog saliva under prey-capturing conditions.­­­­­­­ The scientists think frog tongues could one day help engineers design reversible soft adhesives that could work at high speeds.
