There’s an official Guinness World Record for “World’s Most Dangerous Tree,” and it’s held by the manchineel tree from the Caribbean and Gulf of Mexico. The manchineel’s bark is covered in sap that causes skin to blister and can blind a person if it gets in their eyes. Even standing under the tree in the rain can cause blisters because the sap will drip onto skin.The tree’s fruit, known as the “beach apple” or “death apple,” is slightly sweet but very painful to eat. Ulceration of the mouth and esophagus will occur from just a small bite and consumption can be lethal. Smoke from burning manchineel wood can cause blindness, and the sap has historically been used to coat arrows for hunting. Today it’s an endangered species in Florida. (via Listverse)

Lorises leave their babies alone while they gather food, so to keep them safe, they bathe them in saliva, which causes an allergic reaction in predators. One of the cooler defense mechanisms EVER

“Humans and songbirds like the zebra finch (shown) share genetic changes in brain structures related to speaking and singing, new research shows.”
“A cross section of a lab-grown approximation of a human brain reveals several features, including neurons (green) and neuron-producing stem cells (red).”
A species of small puffer fish create these designs on the ocean floor to attract mates and to act as protection for the eggs the pair may eventually lay.

Nerves. The Bodyworld exhibit is the most amazing art exhibit I’ve ever seen in my life. I wish to see it again. There’s a Chinese version that travels here in Asia. Those bodies come from political prisoners who were excuted for opposing the government and did not give consent to have their bodies plastinated. Oh China.
