Invention Awards 2014: Seal Combat Wounds In 15 Seconds

When bullets or shrapnel strike a soldier, standard first aid calls for stuffing gauze as deep as five inches into a wound and applying pressure. If bleeding hasn’t stopped after three minutes, the old gauze is pulled out—and new gauze shoved in.

There’s room for improvement. Military doctors estimate that, during the most violent years of the wars in Afghanistan and Iraq, blood loss killed about 90 percent of the wounded that might have otherwise survived with better emergency care. To save more lives, a group of veterans, scientists, and engineers known as RevMedx has created a pocket-sized device called XStat: a faster, more effective way to plug wounds. The polycarbonate syringe slides deep into a wound, such as a bullet track. When a user pushes down on the handle, it deposits dozens of pill-size sponges that expand to stem bleeding. Meanwhile, a substance in the sponges fights infection while clotting blood.

7 Scientific Solutions for Annoying Little Problems

Scientists are working to alleviate those maddening, irritating, altogether obnoxious things that can make your everyday life hell. And not a moment too soon!

1. CEREAL DUST

THE DILEMMA Ever notice when you open a box of granola that the nuts and raisins are on top while smaller riffraff lingers at the bottom, making it all but impossible to eat a well-rounded bowl of cereal? This phenomenon is known as the “Muesli Effect,” and it describes the tendency of different size particles to separate, with the largest paradoxically ending up on top and the smallest down below. It also occurs in bags of mixed nuts,

10 Space Problems That Were Fixed With Simple Solutions

Sending something into space costs millions of dollars and takes thousands of man hours, in part due to the fact that every eventuality needs to be prepared for—once that thing is in space, there’s very little you can do from Earth if something goes wrong. And yet, time and time again, something does. And time and time again, the lateral thinkers at NASA rise to the occasion.

10. Skylab’s Heat Shield

Skylab was the world’s first space station and it was damaged and the shielding designed to protect the members of this space station was stripped off the aircraft when it was launched. This made the space station useless (it was an unmanned flight), however, the future usage of this space station was becoming impossible since it was exposed to hazardous radiation and a fix was required quickly. The fix came when Jack Kinzler found a small opening and using fish poles, designed a parasol which was used by the repair team when they went to the space station. Surprisingly, it wasn’t deployed the way it was supposed to and yet it was able to block out as much radiation as was possible with the original heat shields.

Very interesting to see this animation on the airplane movement. Who thought the cross having many airplane per hour as this? Maybe next few years on the road our skies will pack with jumbo jet, commercial airline and traffic light.
