Absorption of light allows 11-cis-retinal to relax from a bent shape (arising from the cis double bond) to a lower energy, all-trans arrangement. The straighter all-trans-retinal can no longer fit in the receptor designed for 11-cis-retinal and is ejected. This change leads to differences in cell membrane potential and, as ions are pumped into the cell, this response turns into a nerve impulse that travels to the brain. That is not the end of the matter; the all-trans-retinal generated by this process is reconverted to 11-cis-retinal by specific enzymes, which can re-bind into the receptor, ready to interact with another photon of light.

page 181 - do you ever just sit stoned in your bedroom and imagine 18th century battles that never happened, all cannon smoke and feathered hats, then proceed to draw elaborate maps clarifying the troop movements?

Me too!

I wish I had access to a pen and paper so I could pass the time doing this right now. Also, a bedroom, something to get me high, food, water, a topical cream for this rash, sunlight, friendship, etc.

" Particles are sensed and connected as remote by smell, HI.. I'm a remote sensing specialist " A deer's olfactory senses are its greatest superpower. Deer use their nose as a primary defense against predators. In fact, a deer's nose functions better than a bloodhound's nose. Olfactory receptors are the key a deer's long nose is loaded with them. They have 800 times more receptors than your nose. But that's not all: The roof of a deer's mouth contains the Jacobsons organ, which sorts out smells. When a deer breathes, it automatically detects various smells in the air, including human scent.

Many Experimental Peptides From MIT May Block SARS-CoV-2 ACE2

The battle against COVID-19 has called to action an army of paramedics, healthcare workers, medical researchers, drug makers and many more to the front line of a global pandemic. A team of researchers from MIT have also taken up arms and decided to join the fight against SARS-CoV-2. The MIT...
