Check out these real-life Spider-Man gloves used to climb straight up a wall

Though we tend to focus on the web-slinging and strength, one the coolest things about Spider-Man is the ability to take off and scale a wall with his super sticky hands. Well, as long as you have these gloves, you should be able to follow right behind him.
Researchers at Stanford have unveiled a new glove project similar to Spider-Man’s wall-crawling — though this is admittedly described as “gecko-inspired” — that allows the wearer to stick to a wall and climb right up. The demo plays out fairly slowly, but with some refinement, you’d think this thing could come in pretty handy for a DIY superhero.
The team basically took the sticky pads geckos use to stick to things and scaled it up to a point where it’s big and efficient enough for a human being. The trick? Clingy, hairlike nano fibers that flatten out when pulled downward and grip via electromagnetic attraction. It also uses a shape-memory alloy to keep from breaking mid-climb. But, as Popular Mechanics notes, it can still be yanked off with a perpendicular tug to continue climbing.
Using springs, they anchored 24 microwedge patches to a flat plate that a person could grab with their hand, the idea being that the 24 patches distribute the force of a climber. However, this is actually a well-tested recipe for failure. Normal springs won't distribute weight as evenly as you'd need. Worse, when a single patch is pulled past its breaking point, the failure can avalanche across the entire plate. 
Cool as this tech might seem, it does have a few limitations. It only works on extremely flat and smooth surfaces like glass, and it does not work in the rain. So clear-weather crime only, would-be superheroes. The pads also get dirty, so keep them wiped down so they’ll remain effective.

Students will send time capsule to Mars

Students will send time capsule to Mars

It’s a (reasonably) safe bet to assume that we'll see manned missions to Mars in this lifetime. And as exciting as that sounds, we're still figuring out all the details. NASA is working on a detailed plan that will have humans on the red planet by 2030, but private companies, like Elon Musk's SpaceX, might get us there even sooner. Now, a group of students want to greet the first Mars human colonists with a time capsule by collecting photos, videos, audio clips, and messages to send to the planet as early as 2017.
This "Time Capsule for Mars" project is led by a group of university students. The plan is to put out a worldwide call to over 10 million people to send in their voice messages, photos, video clips, and text to go into three small Cubesats. The Cubesats will be launched towards Mars via an ion electrospray propulsion system created by MIT’s Space Propulsion Lab. The students hope to develop new technologies for the mission, including inflatable antennae and radiation sensors.
The students already have the support of some heavy hitters, like astronauts Buzz Aldrin, Charlie Precourt and Kent Rominger, who all act as project advisors. The students are also receiving aid from NASA, Boeing, Lockheed Martin and Explore Mars. Although the mission is expected to cost about $25 million, the students hope to raise funds through crowdfunding: they’ll charge $.99 for each upload in the developed world, with third-party countries getting free uploads, paid for by project sponsorships. The idea is for everyone to have the opportunity to send their messages to Mars. Donations will also be accepted on the project's website. *
