Dr. Leland Clark, inventor of the platinum "Clark electrodes" used to detect oxygen in liquid (and allows measurement of blood oxygen levels) also did this famous experiment in "liquid breathing":
Dr. Leland Clark of Cincinnati invented a blood substitute allowing this living mouse to breathe in the liquid, while goldfish inhabit the water floating on top.
After bubbling oxygen through the fluorocarbon, the oxygenated fluid was pumped into the animals’ lungs, and recirculated (about 6 cycles of inhalation and exhalation per minute). Most of the animals who were kept in the fluid for up to an hour survived for several weeks after their removal, before eventually succumbing to pulmonary damage.
Steven Cummer of Duke University and collaborators from FMA Research in Fort Collins, Colorado, managed to take amazing video of atmospheric flashes of light called sprites:
Mysterious flashes of light called “sprites", that occur above thunderclouds during powerful storms, have been captured on film in unprecedented detail by researchers using an ultra-high-speed camera.
The best images yet of the flashes – which resemble a giant undulating jellyfish with its tentacles falling from a halo of light – have allowed the team to pick apart their structure and mechanics.

From the website:
Forget everything you think you know about China and take a couple minutes to ponder these images. Few people in the Western world know about the hidden beauty of China. Well….. of course it helps to have an ace photographer who can capture this land of enchantment as no other has. But these are some truly inspiring photos.
