The Gladiator Spider can make an expandable sticky web like a net. When an insect passes below it, it stretches out the net, lunges downwards and flings the net over the prey.

Map of the World by Natural Skin Color

i’m really dumbfounded that i never realized skin colour is literally just caused by being closer to or farther from the equator and the resulting sun exposure and skin darkening

actually, its an adaptation. natural selection. people with darker skin are selected for in areas near the equator, where the melanin that causes the darker color protects them from radiation and protects them from skin cancer and other health defects, and because they are healthier they can pass on that trait more. people near the poles have lighter skin because it allows them absorb more of the limited sunlight to convert to vitamin d. 

THIS IS THE THING SOME PEOPLE HATE OTHER PEOPLE OVER.Evolution of melanin levels based on geographical location.

Malaysia jet search area too deep for submarine
Associated Press: The search area for the missing Malaysian jet has proved too deep for a robotic submarine which was hauled back to the surface of the Indian Ocean less than half way through its first hunt for wreckage and the black boxes, authorities said on Tuesday.
Search crews sent the Bluefin 21 deep into the Indian Ocean on Monday to begin scouring the seabed for the missing Malaysia Airlines Boeing 777 after failing for six days to detect any signals believed to be from its black boxes.Follow this story on BreakingNews.com here.

Newton’s third law says that forces come in equal and opposite pairs. This means that when air exerts lift on an airplane, the airplane also exerts a downward force on the air. This is clear in the image above, which shows a an A380 prototype launched through a wall of smoke. When the model passes, air is pushed downward. The finite size of the wings also generates dramatic wingtip vortices. The high pressure air on the underside of the wings tries to slip around the wingtip to the upper surface, where the local pressure is low. This generates the spiraling vortices, which can be a significant hazard to other nearby aircraft. They are also detrimental to the airplane’s lift because they reduce the downwash of air. Most commercial aircraft today mitigate these effects using winglets which weaken the vortices’ effects. (Image credit: Nat. Geo./BBC2)
