A University of Central Florida (UCF) student engineering project that began with using artificial intelligence (AI) to track cafeteria forks transformed into a system that will help Orlando Health surgeons perform robotic surgeries more efficiently.

Laura Brattain, a UCF biomedical engineer, mentored six College of Engineering and Computer Science seniors, who developed the AIMS (AI for Medical Surgery) system that keeps track of surgical staples, enabling surgical teams to operate more efficiently, reduce waste and improve sustainability. The new technology was developed as part of the college’s Senior Design capstone course that encourages students to create a usable product before they graduate.

When you pull something—like a rubber band—you expect it to get longer. But what if it did the opposite? What if it suddenly shrunk instead? In a study published on April 14 in Proceedings of the National Academy of Sciences (PNAS), researchers from AMOLF and ARCNL have made this possible. They created structures that snap inward when pulled outward. This surprising behavior defies conventional understanding of materials and opens up exciting applications in soft robotics, smart devices, and vibration control systems.  

Despite being a promising and efficient methodology for producing green hydrogen as a novel energy vector, anion exchange membrane water electrolyzers (AEMWEs) have yet to achieve significant commercial success. This is primarily due to the sluggish and complex oxygen evolution reaction (OER) at the anode, which remains the main bottleneck for this technology. To enhance the OER kinetics with minimum overpotentials, scarce and overpriced noble metal-based electrocatalysts are largely utilized, making the AEMWEs practically unaffordable. Recently, amorphous NiFe mixed oxides with variable Ni/Fe ratios have been synthesized using a simple and affordable sol–gel method, successfully enhancing both the OER activity and operational durability in AEMWEs. This work was published in Industrial Chemistry & Materials in March 2025.

ROCHESTER, N.Y. (May 14, 2025)—Neuroscience technology innovator Cognivue^®, today announced a scientific breakthrough with the launch of the Cognivue Amyloid Risk Measure (CARM)*, a novel metric that predicts the likelihood of the presence of amyloid—a key biomarker of Alzheimer’s disease (AD).¹ Now available as an optional feature on the Cognivue Clarity^® device (based on FDA-cleared technology), CARM represents a significant advancement in the early detection of Alzheimer’s by helping healthcare providers identify those at risk of cognitive impairment, even before symptoms emerge.

Over time, stress and anxiety can build to a point where life’s challenges become overwhelming and cause physical effects. Now, in ACS Applied Materials & Interfaces, researchers report a dental floss pick with a built-in sensor that could monitor stress as part of a daily routine. The device, which accurately senses levels of the stress hormone cortisol in minutes, could help users recognize when it’s time to get help.

In many neurodegenerative diseases, proteins misfold and clump together in brain tissue. Scientists developed a new therapy made of peptides and a sugar that naturally occurs in plants. The therapeutic molecules self-assemble into nanofibers, which bond to the neuron-killing proteins. Now trapped, the toxic proteins can no longer enter neurons and instead harmlessly degrade.
