Watch: New Structures Shrink Instead of Stretching When Pulled

Physics /

Researchers in the Netherlands have developed innovative mechanical structures that, surprisingly, contract — or more precisely, snap inward — rather than expand when pulled. The Science Behind the Phenomenon While it may sound counterintuitive, this unexpected behavior is the result of a creative approach that combines geometry and mechanics, devised by scientists at the AMOLF […]

This Dental Floss Can Reveal Your Stress Levels

Healthcare, Medicine /

While it’s easy to recognize when we’re under intense stress, identifying low-level, chronic stress that lingers in the background is much more challenging. To help with this, researchers at Tufts University have developed a new type of dental floss that can analyze your saliva and provide insight into your stress levels. The Biological Impact of

Air-powered Robot Uses Physics Instead Of Circuits To Walk On “Tube Legs”

Robotics, Science /

While soft-bodied robots are often simple and cost-effective, their movement typically relies on complex electronic systems. That’s not the case with a new model developed by researchers at the AMOLF institute in the Netherlands, which harnesses a physical principle to move its inflatable legs automatically. Innovative Design Using Inflatable Tubes The robot, created by Alberto

Tiny self-Powered Robot Breaks Speed, Agility Record with Simple Design

Applied Science, Robotics /

Standing under 1.5 inches tall—about the height of a LEGO minifigure—the world’s smallest self-contained bipedal robot can start on its own, walk over half a mile per hour, turn, skip, and climb small steps using only its built-in battery, actuator, and control system. Nicknamed “Zippy” by its creators, the robot is the latest development from

Why Fingers Wrinkle in Water may Finally Have an Explanation

Healthcare, Medicine /

After discovering the blood vessels responsible for finger wrinkles in water, young readers of The Conversation’s Curious Kids series had more questions for scientists: “Do the wrinkles always form the same way?” one reader asked. Curiosity Sparks a Scientific Investigation “I thought, ‘I haven’t the foggiest clue!‘” recalls Guy German, a biomedical engineer from Binghamton

InventWood is on the Verge of Mass-Producing Wood Stronger than Steel

Climatology, Earth Science /

It may sound like science fiction, but it originates from a lab in Maryland. In 2018, Liangbing Hu, a materials scientist at the University of Maryland, developed a method to transform regular wood into a material stronger than steel. At first, it appeared to be another eye-catching discovery that might never leave the lab. “People

Discovery of a Resilience-Boosting Molecule May Help Slow the Progression of Parkinson’s Disease

Healthcare, Medicine /

A new study has uncovered a method to prevent cell death, potentially paving the way for treatments that could slow the progression of neurodegenerative diseases such as Parkinson’s. Apoptosis, the body’s ancient “cell suicide” mechanism, is controlled by interactions within the BCL-2 protein family. While some of these proteins support cell survival, others initiate cell

Robotics Company Unveils Next-gen AI for Robotic Arms

Applied Science, Robotics /

Dyna Robotics, a startup specializing in AI-driven robotics, is preparing to launch a new embodied AI model for robotic arms, which it describes as a “major breakthrough.” The model, Dynamism v1 (DYNA-1), enables robotic arms to perform high-precision tasks autonomously over extended periods. To evaluate its performance, DYNA-1 was tasked with continuously folding napkins for
