North Carolina State University researchers have developed a cheetah-inspired soft robot that switches between two stable states to run, jump or climb. The robot has pneumatic two-way bending actuators, a 3D-printed flexible "spine" and a pretensioned spring.
Airbus-France plans to build a satellite to transport materials drilled on Mars back to Earth as part of a joint US-EU venture in the next decade. David Parker, director of human and robotic exploration at the European Space Agency, says the satellite will serve as "the first interplanetary cargo ship."
A ballpoint pen using a special semiconductor ink can be used to draw diagnostic sensors on a person's skin for health monitoring. It's part of a system developed by researchers at the University of Houston that includes a wireless battery pack to convey health data via Bluetooth.
Researchers are using computer modeling to determine how northern New Mexico's land and surface water supply are affected by changes in climate. The studies will help communities better conserve and protect water resources, writes Katrina Bennett, a hydrologist at Los Alamos National Laboratory.
Communities along the Lake Michigan shoreline north of Chicago spent years building the structures that allowed formerly thin beaches to flourish and provide easily accessed summer recreation. However, those structures are being threatened as the lake's waters rise and increasingly challenging weather patterns take their toll, eroding the once plentiful sands.
Houston's Clay Family Eastern Glades are now open to the public, marking a milestone in the city's 10-year, $205 million Memorial Park plan. The glades include the 5.5-acre Hines Lake and wetlands, which will capture stormwater for irrigation and habitat.
With encouragement from his father and grandfather, new ASME President Bryan A. Erler says "there was never a doubt in my mind" that he wanted to become an engineer. In an interview, Erler explores his career and expertise, noting his proudest achievements include the many awards he has received in the latter years of his work.
Computational modeling and simulation in medicine can't replace physical testing but can serve as a supplement by providing a parallel analysis and optimization path. System Insight Engineering's Arlen Ward examines how modeling can work, including the study of disease treatment over the course of a disease as it changes.
Advanced lidar sensors present an opportunity to improve power performance testing efficiency and accuracy, which is especially important as land-based and offshore wind turbines get larger and slight variations in production can have a major effect on project economics, writes Matthieu Boquet of Leosphere. "[W]ind farms are an expensive, long-term investment, but the ease of use, time savings and cost efficiency lidar sensors unlock combine to create a more certain energy generation system," he writes.
