Early birds get worms, but who the fuck likes worms? Science thread

Druhim

So some research was done to compare the sleep cycles and alertness levels of early risers vs night owls

Turns out early risers get the worms, but they also tire sooner. Goooo night owls!

Science thread activate!

Hey! If you get up earlier, you get tired earlier!

how is this science?

a superconducting field powerful enough to repulse the water inside biological organisms

since when is water magnetic?

Water is diamagnetic, which causes it to create a magnetic field opposed to another magnetic field that is affecting it, according to wikipedia.

That's how they get around Earnshaw's theorem, which suggests that stable magnetic levitation against gravity is impossible. It doesn't apply to diamagnetism, which is also what allows mag-lev trains to work.

well, looks like I was wrong also

To be fair, I didn't know, so I looked it up.

MORE INFO WOOOOOO:

As water is predominantly diamagnetic, this technique has been used to levitate water droplets and even live animals, such as a grasshopper and a frog. However, the magnetic fields required for this are very high, typically in the range of 16 teslas, and therefore create significant problems if ferromagnetic materials are nearby.

The minimum criterion for diamagnetic levitation is , where:


χ is the magnetic susceptibility
ρ is the density of the material
g is the local gravitational acceleration (-9.8 m/s2 on Earth)
μ0 is the permeability of free space
B is the magnetic field
is the rate of change of the magnetic field along the vertical axis

Assuming ideal conditions along the z-direction of solenoid magnet:

Water levitates at
Graphite levitates at

I wonder if it's diamagnetic because of ions in solution, or if that's an inherent property of water itself

The very scientific source of Wikipedia:
http://en.wikipedia.org/wiki/Diamagnetism

says that all materials are diamagnetic to some degree.

They also have a picture of a live frog floating above a field of 16 teslas:

Hi, Pip! How's my best friend?

new job is pretty good, but I need more hours

isn't there also plenty of iron in our blood?

wouldn't this create problems?

please note that I'm basing my hypothesis on that scene in X-men when Magneto busts out of jail by ripping the iron out of that fat guy's blood

He had a big ass syringe of it stuck in him the night before by mystique.

MrMonroe

ah right

remind me not to inject myself with a bunch of iron right before I jump on an experimental anti-gravity pad, then

Where's vsove?

Velociraptor's 'killing' claws were for climbing

Phil Manning of the University of Manchester, UK, and colleagues previously showed that Velociraptor's sharp-tipped foot claw could puncture skin and help the dinosaur cling to wounded prey but was not sharp enough to rip the skin open. Now an analysis of the biomechanics of the hand claw suggests it could have supported the dinosaur's weight when it was climbing (Anatomical Record, DOI: 10.1002/ar.20986).

Velociraptor might have used its climbing ability to perch in trees and pounce on prey from above

Huff huff I came as quickly as I could.

That is amazing. It is really quite amazing how perfectly some of the dinosaurs evolved into their particular niches.

You're a smart guy. what's the latest on the future of NASA? I heard there was some big summit for discussing their budget, covering various 10, 20 years plans.

Sorry dru, I almost missed it myself. I got called away with 10 minutes to go and I told the people in the meeting "Uh, yeah, I gotta go, I'll be back in a few"

I am pretty sure they thought I had diarrhea.

They're scrapping it and using the money to relaunch the Geo automobile line.
