Bees up-close

view preview
Barry from Bee Movie has taught us that without bees, we won't survive. These pollinators may terrify us when they are swarming around out at the park, but they are more terrifying if they were not around. What is happening to our bees with domestication? What have we lost? What are we trying to restore? The answers to these questions are in this video. Check it out

Birds of Paradise

view preview
A must see introductory video about paradise birds. This video reveals the astounding beauty of 39 of the most exquisitely specialized animals on earth. After 8 years and 18 expeditions to New Guinea, Australia, and nearby islands, Cornell Lab scientist Ed Scholes and National Geographic photojournalist Tim Laman succeeded in capturing images of all 39 species in the bird-of-paradise family for the first time ever.

Brain just can't catch a break
|
view preview
The importance of adequate, non-distracted, deep sleep could not be emphasized enough. Recent research has put the brain yet again under the spotlight, this time only to shed some light on one more reason we should be getting our sleep and why. Make sure to watch the video above. It is hands down, one of the best TED talks I have listened to. As for now, I'mma go make my CSF flush my amyloid betas Nighty, night!

Can 1 equal 2? Spot the error
|
view preview
A defining features of learning mathematics is being able to read, write, and discover proofs. A proof is a method of communicating a mathematical truth to another person who speaks the "language" of mathematics. It's a way of showing whether a statement made is absolutely true or false. I recently came across a fallacious proof attempting to show that the integer one equals two – shown are the steps to accomplish this. Common sense dictates that this is impossible, but the proof is somewhat convincing to the untrained eye. However, most people with basic algebraic knowledge should be able to pick out the mistake, so take a minute or two to see if you can identify the incorrect step. If you're stuck, don't give up so quickly! It's easier th ...

Can money buy happiness?
|
view preview
I really enjoyed the way the folks at ASAP Science break it down in this video. Long story short, if you want the best bang for your buck, spend your money on others, and stop spending money on material goods. Having a five-dollar latte can be more beneficial than buying a $100,000 Porsche.

Can plastic be converted back to oil?
|
view preview
Start by watching the video below In the video, a Japanese man converts plastic waste into usable oil and fuel using a machine that thermochemically decomposes the plastic in a process known as pyrolysis. Pyrolysis works by thermochemically breaking down material at temperatures above 350 degrees Celsius in the absence of water. This not only physically melts down an object, but also changes its chemical composition so that, in the case of plastic waste, it reverts back into boiling liquid and eventually gas.

Check out the footage of this tricky plant
|
view preview
To tap into scarce water supplies, most desert plants have extensive root systems that burrow deep or spread wide. But one desert moss has a different trick up its sleeve: a thirst-quenching structure called an awn. Awns are tiny, hairlike structures that project from the end of each leaf to capture water (above). For the first time, scientists have examined in detail how this moss ( Syntrichia caninervis) pulls water right from the air using its awns. At the smallest scale, the awns are covered with grooves about 100 nanometers deep and 200 nanometers wide, the perfect size for dew to condense within them when conditions are right. Those nanogrooves lie within larger troughs that measure about 1.5 micrometers deep and 3 micrometers wide, a ...

Chicken-like bird

The greater sage grouse is found in the western parts of the United States and Canada. When mating season is upon the birds, males and females meet at breeding locations known as leks. The males strut around, inflating and deflating the air sacs in their chests to impress the females.
