Worried about the safety rating of that child car seat? Perhaps you should swaddle your progeny in a protective Kevlar cocoon. The Carkoon is a new child seat developed by British company Cool Technologies that wraps your child in protective Kevlar and a fireproof Nomex airbag upon impact. It even calls emergency services for you.
Weaving wool into Kevlar improves the energy and water absorption of the synthetic textile, potentially making bulletproof vests more comfortable and more affordable, according to researchers in Australia.
Tightly woven wool reduces the number of Kevlar layers required to stop a bullet from 36 to 30, and wool's water-absorption qualities could make Kevlar more effective in wet situations.
Liquid armor has been shown to stop bullets more effectively than plain Kevlar, according to British firm BAE Systems. The material could be used to make thinner, lighter armor for military personnel and police officers, the BBC reports.
Materials scientists combined a shear-thickening liquid with traditional Kevlar to make a bulletproof material that absorbs the force of a bullet strike by becoming thicker and stickier.
No stranger to rough landings, NASA just engineered a crash of its own design to test a new crash countermeasure for helicopters. NASA dropped a donated Army MD-500 carrying four crash test dummies from 35 feet, to determine whether a new honeycomb cushion made of Kevlar strapped to the bottom of the copter could absorb the brunt of the impact. The result: a more or less intact MD-500, and the cool impact video below.
