Graphene Composite Could Keep Wings Ice-Free

A thin coating of graphene nanoribbons in epoxy developed at Rice University has proven effective at melting ice on a helicopter blade. The lab melted centimeter-thick ice from a static helicopter rotor blade in a -4° F environment. When a small voltage was applied, the coating delivered electrothermal heat – called Joule heating – to the surface, which melted the ice.

Are wearable health devices effective?

This week's Question: The market for smartwatches and fitness bands is growing, but how effective are today's wearable health devices? A study from Lancaster University, the University of the West of England, and Nottingham Trent says that the technologies are marketed under the premise that they will help improve general health and fitness, yet the majority of manufacturers provide no empirical evidence to support the effectiveness of their products. Evidence for the value of the wearables is anecdotal, according to the researchers, and there is little scientific evidence as to how they improve health. What do you think? Are wearable health devices effective?

Researchers Develop Power-Generating Shoes

An energy-harvesting technology developed by University of Wisconsin-Madison researchers captures the energy of human motion to power mobile electronic devices. The footwear-embedded energy harvester could be especially useful for the military, as soldiers currently carry heavy batteries to power their radios, GPS units, and night-vision goggles in the field.

Would you like to ride in a Hyperloop?

This week's Question: A Massachusetts Institute of Technology (MIT) team took top honors this month at a competition to design the Hyperloop, a high-speed transportation concept from Tesla Motors and SpaceX CEO Elon Musk. In the absence of air or surface friction, the Hyperloop design enables passenger pods to travel through airless tubes at more than 600 mph. Using low-energy propulsion systems, the Hyperloop theoretically utilizes air pressure to “hover” above a track. MIT's team will now have the opportunity to build and test its design in the US. The researchers will perform simulations, try out braking systems, and, with great caution, test dangerously strong magnets. What do you think? Would you like to ride in a Hyperloop?

New 3D-Printed Part Allows NASA to Measure Sea Ice

Slated for launch in 2018, NASA’s Ice, Cloud and land Elevation Satellite-2 (ICESat-2) will carry a 3D-printed part made of polyetherketoneketone (PEKK), a material that has never been used in additive manufacturing, let alone flown in space.
