How plankton gets jet lagged
A hormone that governs sleep and jet lag in humans may also drive the mass migration of plankton in the ocean, scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have found. The molecule in question, melatonin, is essential to maintain our daily rhythm, and the European scientists have now discovered that it governs the nightly migration of a plankton species from the surface to deeper waters. The findings, published online today in Cell, indicate that melatonin’s role in controlling daily rhythms probably evolved early in the history of animals, and hold hints to how our sleep patterns may have evolved.[…]
[The researchers] discovered a group of specialised motor neurons that respond to melatonin. Using modern molecular sensors, [they were] able to visualise the activity of these neurons in the larva’s brain, and found that it changes radically from day to night. The night-time production of melatonin drives changes in these neurons’ activity, which in turn cause the larva’s cilia to take long pauses from beating. Thanks to these extended pauses, the larva slowly sinks down. During the day, no melatonin is produced, the cilia pause less, and the larva swims upwards.
“Step by step we can elucidate the evolutionary origin of key functions of our brain. The fascinating picture emerges that human biology finds its roots in some deeply conserved, fundamental aspects of ocean ecology that dominated life on Earth since ancient evolutionary times”

i just want to be touched really hard
like by a car
hit me with a car
my fucking tits are so big there is literally no position (of standing, laying, or sitting) that is genuinely comfortable.
Gotta love these guys

No, for real, though—this is a thing. Not sure about the science behind it, but it makes me feel fancy and powerful regardless. I highly recommend it.
There actually is legit science behind this. In fact, here’s an entire TED Talk about the science behind it, and the confidence-related chemicals that your brain produces JUST BY YOU STANDING LIKE THIS.
I don’t understand girls who don’t like superhero movies, I mean I get that not all girls like the action and explosions and that stuff but this?
Also a lot of superhero movies are really funny:
And also Tony Stark
