Lowering Fuel Cell Cost with Quinone Mediators and Cobalt
The new fuel cell design produces about 20% of what is possible in commercial hydrogen fuel cells but is about 100 times more effective than biofuel cells that use related organic shuttles.
NTSB Urges System Alert After Close Call at SFO
Air Canada flight 759 was cleared to land on runway 28R in July 2017, but instead lined up with parallel taxiway C where four airplanes were awaiting clearance to take off. The error could have been catastrophic.
Initiative 97: Who’s Land Grabbing Now?
Initiative 97 defines an increased buffer zone between new oil and gas developments and occupied buildings. It questions the role of the Colorado Oil and Gas Conservation Commission (COGCC). Have they been too lenient on an industry that has blatantly disregarded public health and safety? Is the oil and gas industry at fault for over-reaching in an attempt to capture a valuable resource or is this backlash a form of land-grabbing?
OXIS Energy Advances Lithium Sulfur Cell Technology to 450 Wh/kg
OXIS achieved 425 Wh/kg on a high energy 16 Ah pouch lithium sulfur cell design for High Altitude Pseudo Satellites (HAPS) applications.
A Mask That Lets Busy People Send Surrogates to Meetings They Can't Attend
A collaboration between Sony and a Japanese AR/VR researcher allows time-stretched people to hire surrogates to attend conferences and meetings in their absence.
Fixing a Typo on an Iconic New York Bridge
It took legislation for officials to correct how the name of a 50-year-old suspension bridge spanning lower New York harbor is spelled.
Marine Research Submarines to be Outfitted with Soft Robotic Arms
Scientists from the Wyss Institute, Harvard's John A. Paulson School of Engineering and Applied Sciences (SEAS), Baruch College and the University of Rhode Island (URI) have created a new system for handling underwater creatures.
The Netherlands to Launch Mobile Phone Ban for Cyclists
It will soon be illegal for cyclists in the Netherlands to use their smartphones while riding their bicycles, thanks to a new law that will take effect July 2019.
A First for Flat Lenses: Full-Color Imaging
Ordinary simple lenses are limited by an inability to focus light of different colors, but metamaterials science has led researchers to create a flat lens capable of full-color imaging.
