Hubble Reaches New Milestone in Mystery of Universe's Expansion Rate
Pursuit of the universe's expansion rate began in the 1920s with measurements by astronomers Edwin P. Hubble and Georges Lemaître. In 1998, this led to the discovery of "dark energy," a mysterious repulsive force accelerating the universe's expansion. In recent years, thanks to data from Hubble and other telescopes, astronomers found another twist: a discrepancy between the expansion rate as measured in the local universe compared to independent observations from right after the big bang, which predict a different expansion value.

3D Printed Shape Memory Alloy with Superior Superelasticity
Laser powder bed fusion, a 3D-printing technique, offers potential in the manufacturing industry, particularly when fabricating nickel-titanium shape memory alloys with complex geometries. Although this manufacturing technique is attractive for applications in the biomedical and aerospace fields, it has rarely showcased the superelasticity required for specific applications using nickel-titanium shape memory alloys.

Increased Cognitive Demands Offset Low-Back Exoskeleton Advantages
Although novel ergonomic interventions such as industrial exoskeletons have shown promise in reducing the risk of musculoskeletal injuries, new research finds that the cognitive fit (where the wearer has ample mental resources available to accurately operate the exoskeleton while conducting their daily work tasks) of such wearable robotic solutions in the workplace may impose newer risks on workers.

Pacemaker-Like Devices Could Restore Lost Oral Function
Even the mundane act of swallowing requires a well-coordinated dance of more than 30 muscles of the mouth. The loss of function of even one of these due to disease or injury can be debilitating. For these people, nerve stimulation offers a ray of hope to regain some of their lost oral function.

Machine Learning Can Reduce Worry About Nanoparticles In Food
While crop yield has achieved a substantial boost from nanotechnology in recent years, alarms over the health risks posed by nanoparticles within fresh produce and grains have also increased. In particular, nanoparticles entering the soil through irrigation, fertilizers and other sources have raised concerns about whether plants absorb these minute particles enough to cause toxicity.

Technology to Monitor Mental Wellbeing Right at Your Fingertips
To help patients manage their mental wellness between appointments, researchers have developed a smart device-based electronic platform that can continuously monitor the state of hyperarousal, one of the signs of psychiatric distress. They said this advanced technology could read facial cues, analyze voice patterns and integrate readings from built-in vital signs sensors on smartwatches to determine if a patient is under stress.
