Innovative lightweight metal foam set to protect astronauts

Lightweight composite metal foams are effective at blocking X-rays, gamma rays and neutron radiation, say researchers from North Carolina State University who believe their discovery holds promise for use in nuclear safety and space exploration. “This work means there’s an opportunity to use composite metal foam to develop safer systems for transporting nuclear waste, more […]

Scientists merge electronics with bio-printed ear

Using off-the-shelf 3D printing tools, Princeton scientists have built a functional cell-cultured ear that can “hear” radio frequencies. The bionic ear is the team’s first effort to create a cybernetic organ: one that not only replicates a human ability, but extends it using embedded electronics “There are mechanical and thermal challenges with interfacing electronic materials […]

“Nanosponge” removes toxins from bloodstream

Nanoengineers at the University of California, San Diego say they have created a “nanosponge” that is capable of safely removing a broad class of dangerous substances from the bloodstream – including toxins produced by MRSA, E. coli, venomous snakes, and bees. In a study using the toxin from MRSA, inoculation with nanosponges enabled 89 percent […]
