After starting medical marijuana treatment, this 3-year-old’s daily seizures went from 100 to 10 

To combat her constant epileptic seizures, Addyson Benton’s family relocated to just outside Denver, Colorado, where they could legally purchase a marijuana-extract specially designed for Addyson using THCA, a biosynthetic precursor of THC, the active component of cannabis. Within hours of taking the patch, Addyson’s health took a 180 — and improved several common functions.

From 2009 to 2013, the research schooner Tara traversed the globe, carrying a multinational team of scientists. They surveyed the critical foundation of the marine food chain (a foundation we know dangerously little about): plankton, bacteria, protists, viruses and small animals. All in all, they found more 35,000 different kinds of organisms — many of them previously unknown to science. Read all about it!

The Electrification of Human Corpses

In 1780 the Italian anatomy professor Luigi Galvani discovered that a spark of electricity could cause the limbs of a dead frog to twitch. Soon men of science throughout Europe were repeating his experiment, but it didn’t take them long to bore of frogs and turn their attention to more interesting animals. What would happen, they wondered, if you electrified a human corpse?

The simple coalescence of a drop with a pool is more complicated than the human eye can capture. Fortunately, we have high-speed cameras. Here a droplet coalesces by what is known as the coalescence cascade. Because it has been dropped with very little momentum, the droplet will initially bounce, then seem to settle like a bead on the surface. A tiny film of air separates the drop and the pool at this point. When that air drains away, the drop contacts the pool and part–but not all!–of it coalesces. Surface tension snaps the remainder into a smaller droplet which follows the same pattern: bounce, settle, drain, partially coalesce. This continues until the remaining droplet is so small that it can be coalesced completely. (Image credit: Laboratory of Porous Media and Thermophysical Properties, source video)

The octopus can see with its skin

Octopuses are well known for changing the colour, patterning, and texture of their skin to blend into their surroundings and send signals to each other, an ability that makes them both the envy of, and inspiration for, army engineers trying to develop cloaking devices. As if that wasn’t already impressive enough, research published today in the Journal of Experimental Biology shows that octopus skin contains the pigment proteins found in eyes, making it responsive to light.

An Extraordinary Glimpse into the First 21 Days of a Bee’s Life in 60 Seconds

In an attempt to better understand exactly what happens as a bee grows from an egg into an adult insect, photographer Anand Varma teamed up with the bee lab at UC Davis to film the first three weeks of a bee’s life in unprecedented detail, all condensed into a 60-second clip. The video above presented by National Geographic doesn’t include commentary, but Varma explains everything in a TED talk included below. The primary goal in photographing the bees was to learn how they interact with an invasive parasitic mite that has quickly become the greatest threat to bee colonies. Scientists have learned to breed mite-resistant bees which they are now trying to introduce into the wild. Learn more about it in this video:
