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.

Dye that Changes Colour Like a Moodring

"Color-changing hair might seem like something out of a fantasy novel, but Lauren Bowker of The Unseen has made it a reality. Bowker, a chemist and fashion designer, is known for her “high-fashion alchemy.” She’s previously created hue-shifting purses as well as other air sculptures that use science to produce a stunning visual effect. Now, she’s turning her attention towards color-changing hair dye that’s controlled by temperature—when there’s a dramatic spike or drop, the dye seemingly has a mind of its own... Each hue reacts to either bodily or environmental temperatures. Blushing, for instance, causes your body temperature to rise and as a result, a shift in color... Weather is also a factor. With one color combination, stepping into chilly weather shifts blonde hair to a fitting icy blue."
