Zombie Deer Disease, Mad Cow Disease and the Jump to Humans

Mad Cow Disease or bovine spongiform encephalopathy, has been around for years.  It jumped to humans in the '90's and people still die from it. Basically, their brains are eaten away and there is no cure.  Now researchers have found a similar disease in deer.  The disease causes their brains to become like swiss cheese as prions wreak havoc inside their heads.  The jump to humans is not fiction.  It is feared that this could happen soon.  The whole article can be found here.

16 Billion Units on the Scoville Scale!

The Carolina Reaper is the world's hottest pepper coming in at 1.6 million on the Scoville scale of hotness.  Now, a cactus from Morroco has obliterated that with heat on the Scoville scale of 16 billion units!  The active ingredient is resiniferatoxin. What possible use could that kind of heat be used for?  How about killing pain receptors in bad knees? Or killing pain associated with cancer?  The article found in wired.com has much more information on this unique and mind-searing level of heat!

Atoms, Empty Space and Density

If atoms are mostly empty space, many wonder why matter is not transparent.  Here's a simple answer from sciencefocus.com

While atoms are indeed mostly empty space, the void is filled with the electromagnetic fields generated by the electrons within the atom. These affect light waves as they move through materials, preventing them from passing straight through unimpeded. Switching to radiation of shorter wavelength, like X-rays or gamma rays, allows even relatively dense materials to become transparent.

Rotting Corpses - Homes for Babies

Mothers love their children, even in the insect world. The Burying Beetle is no exception. This beetle uses corpses of dead animals to create a wonderful nursery for her young.

Spray It and Hear It

Antennas have been around for decades and are a necessity for wireless communication of any sort.  The old TV antennas which used to be seen on most homes have given way to cable or satellite dishes.  And many antennas are bulky and large. Now scientists have developed an antenna that is thinner than human hair and that can be sprayed onto any surface and used to capture waves of energy.  Read this fascinating article from newatlas.com about these sprayable antennas.
