Bees up-close

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

Barbados thread snakes
|
view preview
At first, it just looks like a worm. But when you peek closer, it slithers like a snake. It sticks its tongue out like a snake. It creeps you out like a snake. Discovered under a rock in 2006 in Barbados, this thread snake is as thin as spaghetti and smaller than any of the 3,100 other known snake species. Researchers believe it is the smallest a snake can evolve to be.

An essential bone lost
|
view preview
Despite slang terms that imply otherwise, the human penis contains no bones. The same cannot be said for many of our closest evolutionary relatives: Chimpanzees and bonobos both have penis bones (a macaque one is pictured, left), also known as bacula. To find out why some primates have the feature whereas others don’t, researchers traced the bone’s evolutionary history through time. The baculum first evolved between 145 million and 95 million years ago, as reported in the Proceedings of the Royal Society B. That means it was present in the most recent common ancestor of all primates and carnivores. Why some descendants, like humans, lost their bacula appears to be due to differences in mating practices: In primates, the presence of a penis ...

Here's how 9,000 years of selective breeding has changed corn from a wild grass - that required a hammer to peel - to the juicy yellow ears of deliciousness we know today.

A parrot with a wicked hairstyle
|
view preview
This is a Palm Cockatoo, also know as the Goliath Cockatoo. Palms are distinguished by their size, huge beak (second only to the Hyacinth Macaw among psittacines and largest proportionate to size), solid black feather coloration, large open crest, bare red cheeks, and red and black tongue. You have to see their tongues to believe the coloration. It's amazing. Palm Cockatoos are severely threatened. They are CITES Appendix I birds and are protected in Australia. As a testament to their rarity, typical prices in the U.S. for Aterrimus Palms are around $8000 and Goliaths around $14,000. Perhaps contributing to their rarity is the fact that, according to both Low and Forshaw, they lay only one egg per clutch. ...

A fascinating looking whale
|
view preview
This is Migaloo, the albino white humpback whale. His name is derived from an Aboriginal word that means “white fella.” Migaloo is a favorite for whale watching enthusiasts. He is believed to be the only documented white humpback whale in the world. He was discovered in 1991 and quickly became popular with tourists and locals alike. Since then, sightings have been rare. He migrates from Antarctica to Australia on a yearly basis, and some years he slips by undetected. Most of these photos were taken in 2012 on Migaloo’s return to Antarctica. ...
