Next Generation Spacesuit like Second Skin

Scientists from MIT have designed a next-generation spacesuit that acts practically as a second skin, and could revolutionize the way future astronauts travel into space. (Photo : Jose-Luis Olivares/MIT)
Astronauts are used to climbing into conventional bulky, gas-pressurized spacesuits, but this new design could allow them to travel in style. Soon they may don a lightweight, skintight and stretchy garment lined with tiny, muscle-like coils. Essentially the new suit acts like a giant piece of shrink-wrap, in which the coils contract and tighten when plugged into a power supply, thereby creating a “second skin.”
"With conventional spacesuits, you’re essentially in a balloon of gas that’s providing you with the necessary one-third of an atmosphere [of pressure,] to keep you alive in the vacuum of space," lead researcher Dava Newman, a professor of aeronautics and astronautics and engineering systems at MIT, said in astatement.
"We want to achieve that same pressurization, but through mechanical counterpressure - applying the pressure directly to the skin, thus avoiding the gas pressure altogether. We combine passive elastics with active materials. … Ultimately, the big advantage is mobility, and a very lightweight suit for planetary exploration."
Newman, who has worked for the past decade on a design for the next-generation spacesuit, describes the new garment in detail in the journal IEEE/ASME: Transactions on Mechatronics.
The MIT BioSuit’s coils, which are a main feature of the outfit, are made from a shape-memory alloy (SMA). At a certain temperature, the material can “remember” and spring back to its engineered shape after being bent or misshapen.
Skintight suits are not a novel idea, but in the past scientists have always struggled with the question: how do you get in and out of a suit that is so tight? That’s where the SMAs come in, allowing the suit to contract only when heated, and subsequently stretched back to a looser shape when cooled.
Though the lightweight suit may not seem at first like it can withstand the harsh environment that is outer space, Newman and his colleagues are sure that the BioSuit would not only give astronauts much more freedom during planetary exploration, but it would also fully support these space explorers.
Newman and his team are not only working on how to keep the suit tight for long periods of time, but also believe their design could be applied to other attires, such as athletic wear or military uniforms.
"An integrated suit is exciting to think about to enhance human performance," Newman added. "We’re trying to keep our astronauts alive, safe, and mobile, but these designs are not just for use in space."

A great addition to your garden or back yard. - Bee watering station. 
Bees need water just like we do but often times drown in open water. To make a bee watering station you can either do what is shown in the photo above and fill the bowl of a dog/cat watering jug with stones or you can fill a small dish with marbles and add water to that. That way the bees have something to land on!

First post to get this many notes, and I’m so glad it’s this one. ^_^

No fuck bees kill them all

Kill all bees huh? Bees are responsible for pollinating around 80% of agriculture. Bees die, you die. Do research and get over your fears.

bees are so important save the bees

We need bees or the planet will die.
And we just happen to have one of these old dog watering dishes around somewhere. View Larger

Fun fact time: many of my old acquaintances still make joking comments whenever they see me wearing pink, because as a child (and honestly pretty much right up to high school) I would refuse to associate with any pink objects. 
It wasn’t because I didn’t like pink, it was because since I appeared female I was supposed to/ it was immediately assumed that I did and therefore it pissed me the ever-loving fuck off. I was ashamed to like it, which is terrible because pink is an awesome color. But when you shove it down young girls throats it gets really old, really fast. 
Give the child the fucking rainbow, and if they pick pink, it’s not because they are female and/or effeminate, it’s because they like the color pink. 

THIS.

Gosh this

Holy fuck
