Waiting hours for a cellphone to charge may become a thing of the past, thanks to an 18-year-old high-school student’s invention. She won a $50,000 prize Friday at an international science fair for creating an energy storage device that can be fully juiced in 20 to 30 seconds.
Everybody, remember this face.
Remember this name.
If this becomes a commonly used & highly lauded discovery, at some point a White guy is going to take credit, even if he has to word it like “Improved upon a previous…”
No no no
Remember this brown girl.

Can someone from the sciencey side of tumblr please explain this ?
This is called shape memory. It’s made from an alloy of titanium and nickel (I believe it’s called nitinol). It has the ability to “remember” the shape it’s taken.
When cold you can bend it whatever which way, but once you heat it (or in this case put it in what I presume is hot water) it will take the original shape.
I know new stuff now!!
It took me 3 minutes to learn an information I would learn in school for like 3 years

Window Socket - Kyuho Song & Boa Oh
So this is an absolutley brilliant idea! Just attach the plug on to a window and it will harness solar energy. A small converter will convert it into electricity which can be freely used as a plug when you are in the car, on a plane or outside.
Love this design and I really think it has a great potential.
Hubble has spotted an ancient galaxy that shouldn’t exist
This galaxy is so large, so fully-formed, astronomers say it shouldn’t exist at all. It’s called a “grand-design” spiral galaxy, and unlike most galaxies of its kind, this one is old. Like, really, really old. According to a new study conducted by researchers using NASA’s Hubble Telescope, it dates back roughly 10.7-billion years — and that makes it the most ancient spiral galaxy we’ve ever discovered.
“The vast majority of old galaxies look like train wrecks,” said UCLA astrophysicist Alice Shapley in a press release. “Our first thought was, why is this one so different, and so beautiful?”

underthevastblueseas: Underwater Rivers?
A group of amateur cave explorers discovered a river in Mexico with banks, trees and leaves just like an ordinary river, but with an additional metric shit ton of “WTF,” because they were hovering 25 feet over it in scuba gear when they discovered it.
While underwater water doesn’t seem possible, the “river” is actually a briny mix of salt water and hydrogen sulfide. It’s much more dense than regular salt water, so it sinks to the bottom and forms a distinct separation that acts and flows like a river.
Deep sea lakes look like normal lakes, complete with sandy and rocky shores. Scientist call these lakes “cold seeps,” but they’re a hotbed for life, because apparently waterfront real estate is a hot commodity under water, too. The “rocky” shores are actually made up of hundreds of thousands of mussels. Even weirder, the lakes under the waves have waves of their own.

How Microorganisms Move
This week’s episode of Coma Niddy University is a science parody to How Animals Eat Their Food. Watch me make a fool of myself imitating how different microbes move around.

In the dry lakebed of Racetrack, Death Valley stones as big as 700 pounds mysteriously slide across the surface of the earth without any notable external forces acting upon them. While some researchers believe a combination of natural events, such as wind and ice, cause these stones to “sail”, others question this theory pointing out that the stones don’t follow a predictable path and change directions abruptly.
THE PIONEERS USED TO RIDE THESE BABIES FOR MILES
Opalized wood. Petrified wood is basically fossilized wood that has had it’s organic matter replaced by a mineral such as agate, bit by bit, as it decomposes. The wood structure is maintained, but the wood fibers are slowly changed into stone. Sometimes a jasper, quartz, pyrite or even opal(shown above) can be found fossilized in wood.
Mihoko Ogaki’s sculpture installations are a poetic interpretation of Carl Sagan’s assertion that we’re all made of star stuff. She sculpts dead and dying figures that beam pinpoints of light from the inside, turning them into the origins of glorious galaxies at the moment of death.
Ogaki’s work often reflects a fascination with both the beginning and the end of human life, portraying it in ways that attract our fascination with moments in human development we sometimes push from our consciousness. Her dying figures are sometimes distressing and sometimes meditative, but when you turn off the lights, the LEDs surround the viewer with a brilliant reminder that so much exists in the universe beyond that single human life.
