Flowers emit a small electrical field into the atmosphere. The air in motion bends a bumblebee's tiny hairs, triggering a nerve signal. The playtpus and spiny anteater are also able to sense electrical fields, but only in water.
Solar impulse is the first solar-powered airplane to circumnavigate the earth, flying day and night over 26,000 miles, using zero fuel. The plane's journey included 17-legs, crossing 4 continents, 3 seas, and 2 oceans, covering 42,000 km in 16 months. The 17,000 solar panels on top of the wings power the plane during the day, while the energy stored in 4 battery units under the wings power the plane at night.
An amazing blind cave fish walks up rocks, waterfalls and sand bars. The cave fish uses its pelvis to generate a rocking momentum to hold its weight up and move forward on a solid surface like a salamander. Fewer than 2,000 exist in the world, found in only 8 caves in Mae Hong Son Province, Thailand.
There's a new catalog of Earth's rarest minerals. 100 of the 5,000 known minerals make up 99% of Earth's crust. Another 2,500 are found at only five locations on Earth or fewer. The total amount of one of the rarest minerals on Earth might fill a shot glass or even a thimble. Among these minerals are Painite, Navadaite, Bridgmanite, Fingerite, and Cobaltarthurite.
The longest living vertebrate on Earth is the 400-year-old Greenland Shark. 13–16 feet long at maturity, they grow only half an inch per year. Highly poisonous flesh protects the Greenland Shark from predators, allowing slow maturity and long life. Surprisingly, 90% of some populations of Greendland sharks are blind, due to parasites that attach to their corneas.
Paleontologists found the fossil of a pregnant T-Rex in Montana. Evolutionary biologists confirmed medullary bone in the femur, a type of bone with extra calcium deposits, present only in female egg-laying creatures during the process of laying eggs. More than 50 Tyrannusaurus Rex specimens have been found, including Sue, the largest and most complete fossil (~90%).
