NASA Teams with Microsoft to Let Scientists “Work” on Mars

NASA and Microsoft have teamed up to develop software called OnSight, a new technology that will enable scientists to work virtually on Mars using wearable technology called Microsoft HoloLens. OnSight will give scientists a means to plan and, along with the Mars Curiosity rover, conduct science operations on the Red Planet.

Will autonomous car trends lead to lost jobs?

This week’s Question: As an increasing number of automakers develop autonomous or semi-autonomous cars, some critics are concerned that the number of vehicles on the road will be reduced and jobs will be lost, especially those in motor vehicle parts manufacturing and professional driving sectors. What do you think? Will autonomous car trends lead to lost jobs?

Microcapsule Method Captures Carbon

Researchers has developed a novel class of materials that enable a safer, cheaper, and more energy-efficient process for removing greenhouse gas from power-plant emissions. The team, led by scientists from Harvard University and Lawrence Livermore National Laboratory, employed a microfluidic assembly technique to produce microcapsules that contain liquid sorbents, or absorbing materials, encased in highly permeable polymer shells. The capsules have significant performance advantages over the carbon-absorbing materials used in current capture and sequestration technology.The new technique employs an abundant and environmentally benign sorbent: sodium carbonate, which is kitchen-grade baking soda. The microencapsulated carbon sorbents (MECS) achieve an order-of-magnitude increase in CO2 absorption rates compared to sorbents currently used in carbon capture. The carbon sorbents are produced using a double-capillary device in which the flow rates of three fluids — a carbonate solution combined with a catalyst for enhanced CO2 absorption, a photo-curable silicone that forms the capsule shell, and an aqueous solution — can be independently controlled.The MECS-based approach could also be tailored to industrial processes like steel and cement production, which are significant greenhouse gas sources.SourceRead other Materials tech briefs.

Smaller Lidars Could Let UAVs Conduct Underwater Scans

Bathymetric lidars – devices that employ powerful lasers to scan beneath the water's surface – are frequently used to map coastal waters. At nearly 600 pounds, the systems are large, heavy, and require costly, piloted aircraft to carry them. But a team at the Georgia Tech Research Institute (GTRI) has designed a new approach that could lead to bathymetric lidars that are much smaller and more efficient than the current full-size systems. The new technology, developed under the Active Electro-Optical Intelligence, Surveillance and Reconnaissance (AEO-ISR) project, would let modest-sized unmanned aerial vehicles (UAVs) carry bathymetric lidars.

New Device Measures How Birds Take Flight

It's quite easy to look at a bird and deduce that it flies by flapping its wings, but understanding exactly how a bird generates lift has long eluded scientists. Now engineers at Stanford have developed a device that precisely and humanely measures the forces generated by a bird's wings while in flight. The work promises to answer many mysteries of bird flight, providing aid in the design of innovative and efficient unmanned aerial vehicles, known as UAVs or, more recently, drones.
