if you throw them off a cliff while on fire into a river infested with starving predators, and they live, then they are a witch.
Burn them!

A Southern California start-up backed by Google and prominent venture capital firms announced on Wednesday a technology it claimed could slash the electricity consumption of a wide range of devices like industrial motors, hybrid cars, computers and cellphones.
The result could be electric cars that drive farther without recharging, the disappearance of bricklike device chargers and solar panels that generate more electricity, according to the founders of Transphorm.
The company, based in Goleta, Calif., has developed a power conversion module that it says cuts energy waste by 90 percent. Currently, about 10 percent of the energy generated in the United States is lost as electricity because it is converted from alternating current to direct current and back, according to Umesh Mishra, Transphorm’s chief executive.

"Sedate a Plant, and It Seems to Lose Consciousness. Is It Conscious?"
"The electrical activity that moves across neurons is thought by some scientists to contribute to human consciousness. If electrical activity is being disrupted by anesthetic in plants, too, causing them to “lose consciousness,” does that mean, in some way, that they are conscious?"

I good analogue of quantum entanglement not breaking the speed of light law...
The way people get around the idea that entanglement implies instantaneous communication is that no actual information is passed when the entangled particles affect each other. The argument is as follows (using a non-QM example):
Say you agree to send out two beams of light to your two friends who live on opposite sides of the galaxy (you live in the middle). Ahead of time you tell them that if one of the beams of light is red the other will be blue. So you send the blue beam to your friend on one side and immediately she knows that your other friend is receiving a red beam at the same time. Aha! You say, my friends have now communicated at a speed faster than the speed of light and violated relativity, but no real information has been passed between them. You have told both of them at a normal sub-luminal speed about what you just did and that's all. (A way of proving there's no faster than light communication is that you could lie and send them both the same coloured beam of light and they would never know!).
With QM is gets a bit more complicated because theoretically no-one knows the state of the particle until it has been observed, but you still cannot affect the state of the particle so the argument is the same.

First monkey–human embryos reignite debate over hybrid animals
The chimaeras lived up to 19 days — but some scientists question the need for such research.

- I used to love doing this in Universe Sandbox - so sad seeing all the stars that get flung into the absolute abyss of spacedetritus

- I plan to stick around for thishotroddy
- Curious if this would even effect life on earth (if still there) except for providing a new set of constellations.wagshaft
- Most likely not. Solar systems tend to stay intact as stars are so far apart even durin a collision like this.monospaced
- < yes. I've read that there would be very few star collisions at all.sarahfailin
- < read that too, its not as much stars colliding then 900 trillion meteor orbits getting messed withmoldero

Study shows how taking short breaks may help our brains learn new skills

"The researchers found that during rest the volunteers’ brains rapidly and repeatedly replayed faster versions of the activity seen while they practiced typing a code."
