WTF is LIGO & Why am I Hearing so Much About It?

LIGO-Laser interferometer Gravitational-Wave Observatory (say that 5 times fast) observes gravitational waves.  Gravitational waves are ripples in the curvature of spacetime. No this is not a scifi movie.  At the point of a giant cataclysmic events such as the merging of two neutron stars or blackholes, binary stars, white dwarfs or supernovae.. These ripples were speculated by the Father of relativity himself, Einstein in 1916 when he published his Theory of Relativity. Gravitational waves transport energy in the form of gravitational radiation (similar to electromagnetic radiation) at the SPEED OF LIGHT!!!! WHOA DUDE

 

Eye Candy has a Whole New Meaning!- Don't Deprive Your Eyes!

James Hurley and colleagues has now shown that the retina’s rods and cones burn glucose and then convert the leftovers into a fuel called lactate. They then feed that back to the RPE-retinal pigment epithelium. The team discovered that RPE’s power plants—the mitochondria—burn lactate to power the RPE. Hurley explains, “That allows the glucose to go through without being consumed.” If the RPE is deprived of lactate, then those cells switch to burning the glucose instead of delivering it to the retina and with glucose shut off, the retina cells can die.
