Adrianne Haslet-Davis dances again for the first time since the Boston terrorist attack last year. 

When the bombs went off at the Boston Marathon finish line, Adrianne Haslet-Davis lost the lower half of her left leg in the explosion. She’s a ballroom dance teacher, and she assumed she would never dance again. With most prosthetics, she wouldn’t.

But Hugh Herr, of the MIT Media Lab, wanted to find a way to help her. He created a bionic limb specifically for dancers, studying the way they move and adapting the limb to fit their motion. (He explains how he did it here.)

At TED2014, Adrianne danced for the first time since the attack, wearing the bionic limb that Hugh created for her.  

Hugh says, “It was 3.5 seconds between the bomb blasts in the Boston terrorist attack. In 3.5 seconds, the criminals and cowards took Adrianne off the dance floor. In 200 days, we put her back. We will not be intimidated, brought down, diminished, conquered or stopped by acts of violence.”

Amen to that, Hugh.

what i love about mythbusters is that once they bust a myth they manipulate their variables until something finally explodes bc we all know why you’re really watching this show

First-to-market biometric payment system scans your hand of it’s vein layout to identify the customer and their account.

To those unfamiliar with vein biometrics, the way your veins are structured around your body are more unique than a fingerprint, therefore considered a far more accurate form of personal identification - video from the University of Lund, Sweden below:

Paying for a coffee or lunch by simply scanning your palm still sounds like science fiction to most of us. However, an engineering student at Lund University in Sweden has made it happen - making his the first known company in the world to install the vein scanning technique in stores and coffee shops.

If you thought the post on twins sharing consciousness was awesome, wait until you hear this.

A 44-year-old French man one day went to the trip to the doctor’s because he felt a pain in his left leg. He’s a married man with two kids and a steady job.

Doctor’s found that he had hydrocephalus as a child (when your brain is filled with fluids) so they decided to run some brain scans.

What they found was that the majority of his head was filled with fluid. Over time, the buildup caused his lateral ventricles to swell so much that his brain had been flattened to a thin sheet.

Doctors estimated that his brain mass had been reduced by at most 70%, affecting the areas in charge of motion, language, emotion, and, well, everything.

Shockingly, he was fine. While his IQ was only 75, he wasn’t mentally challenged. He held a steady job, raised a family, and didn’t have trouble interacting with others.

Over time, his brain had adapted to all that pressure, and even though he had fewer neurons that most, Jacques was still a fully functional human being.

The doctors drained the fluid and while his brain is much smaller now, he is still a healthy individual with a normal life.

Window frost (also called fern frost or ice flowers) forms when a glass pane is exposed to very cold air on the outside and moderately moist air on the inside. If the pane is not a good insulator (such as a single pane window), water vapour condenses on the glass forming patterns. The glass surface influences the shape of crystals, so imperfections, scratches, or dust can modify the way ice nucleates. If the indoor air is very humid, rather than moderately so, water will first condense in small droplets and then freeze into clear ice.

Just A Reminder Of How Small We Are

This is the distribution of mass in the different planets, Mercury, Venus, Mars, and Earth making up just 1%.

And this is a distribution of all the mass in the solar system, including the sun - all the planets make up that tiny 0.14% left over after the sun…

The green machine

The structural slab of the city is carried on 4 Crawlers. These machines with caterpillar runners were designed to carry NASA rockets from the manufactory to the launching pad and can be driven on many terrains with a considerable load.

The mobile oasis takes advantage of hostile elements of the Saharan desert; a powerful sun, the wind and strong thermal amplitude between day and night time temperatures.

The GREEN MACHINE is energetically autonomous.

Better still it generates some electricity thanks to its solar towers, and produces water in order to irrigate passed over territories.

On its edges, the Green Machine Oasis is equipped with a number of low-tech systems such as:

  • 9 balloons producing 450m3 of daily water from air condensation. Two thirds of it are dedicated to the irrigation of Sahara. The same balloons are equipped with turbines which generate some renewable energy.
  • 9 Solar Towers producing 450kw/ day. Solar energy in the Saharan desert is between 2000 - 3000 kWh/m² a year. A potential which the project exploits by using Solar Towers that channel warm ground level air up through turbines to produce electricity.
  • 24 500m2 of the cereal fields, directly processed in factories dedicated to the Saharan seeding.
  • 4 500m2 of the hydroponic agricultural greenhouses  more thrifty in water and in energy.
  • Bioreactors to fertilize the grounds. The solid and liquid organic waste (after methanation and composting) the fermentable products, the waste water are recycled in a loop short and local in artillery with plowing.
  • Housing, schools, community restaurants, places of relaxations and pleasure gardens are included in the city.
