Empa has developed an innovative, electrohydraulically actuated valve train for internal combustion engines, that enables completely free adjustment of stroke and timing, while at the same time being robust and cost effective. This valve train was mounted on a serial production engine and has been running successfully for several months. The new technology saves up to 20% fuel.
A collaborative team at the Wyss Institute, Harvard SEAS, and the University of Nebraska Omaha reports in Science that they now have developed the first portable exosuit that can assist the extension of the hip joint during both walking and running. The team successfully tested their wearable robot in uneven outdoor environments while wearers walked uphill, and walked and ran at different speeds.
Researchers at the University of Waterloo have integrated the use of blockchain into energy systems, a development that could result in expanded charging infrastructure for electric vehicles.
Researchers from the University of New Hampshire's Marine School are part of the crew, led by National Geographic Explorer-at-Large Robert Ballard, that is setting out to find answers to disappearance of famed pilot Amelia Earhart. UNH has developed an autonomous surface vehicle (ASV), or robot, that can explore the seafloor in waters that may be too deep for divers.
Researchers are paving the way toward greater safety for coastal residents and infrastructure by developing a better means of modeling the destructive force of tsunami waves.
Europe has the capacity to produce more than 100 times the amount of energy it currently produces through onshore windfarms, new analysis from the University of Sussex and Aarhus University has revealed.
A Columbia Engineering-designed robotic brace that supports the neck during its natural motion is the first device shown to dramatically assist ALS patients in holding their heads and actively supporting them during range of motion. The brace should improve patients' quality of life, not only in improving eye contact during conversation, but also in facilitating the use of eyes as a joystick to control movements on a computer, much as scientist Stephen Hawkins did.
A US Army project discovery upends previous notions about how metals deform and could help guide the creation of stronger, more durable materials for military vehicles.
Electromagnetic fields might help prevent some breast cancers from spreading to other parts of the body, new research has found. The study showed that low intensity electromagnetic fields hindered the mobility of specific breast cancer cells by preventing the formation of long, thin extensions at the edge of a migrating cancer cell.
'Hydrostatic legless jumping' launches a 3-millimeter maggot of a goldenrod gall midge 20-30 body-lengths away with acceleration rivalling the best legged leapers. The larva latches its head to its tail with a previously unknown adhesive and squeezes some internal fluids into its tail section for launch pressure. This style of flight is about 28 times more efficient than crawling, a finding that may intrigue soft robotics.
