Published Milk reaction inspires new way to make highly conductive gel films



A research team has developed what they call a 'dip-and-peel' strategy for simple and rapid fabrication of two-dimensional ionogel membranes. By dipping sustainable biomass materials in certain solvents, molecules naturally respond by arranging themselves into functional thin films at the edge of the material that can easily be removed using nothing more than a simple set of tweezers.
Published Robotic proxy brings remote users to life in real time



Researchers have developed a robot, called ReMotion, that occupies physical space on a remote user's behalf, automatically mirroring the user's movements in real time and conveying key body language that is lost in standard virtual environments.
Published Extracting the best flavor from coffee



Researchers explore the role of uneven coffee extraction using a simple mathematical model. They split the coffee into two regions to examine whether uneven flow does in fact make weaker espresso. One of the regions in the model system hosted more tightly packed coffee than the other, which caused an initial disparity in flow resistance. The extraction of coffee decreased the flow resistance further. Understanding the origin of uneven extraction and avoiding or preventing it could enable better brews and substantial financial savings by using coffee more efficiently.
Published The influence of AI on trust in human interaction



As AI becomes increasingly realistic, our trust in those with whom we communicate may be compromised. Researchers at the University of Gothenburg have examined how advanced AI systems impact our trust in the individuals we interact with.
Published Scurrying centipedes inspire many-legged robots that can traverse difficult landscapes



Intrigued to see if the many limbs could be helpful for locomotion in this world, a team of physicists, engineers, and mathematicians are using this style of movement to their advantage. They developed a new theory of multilegged locomotion and created many-legged robotic models, discovering the robot with redundant legs could move across uneven surfaces without any additional sensing or control technology as the theory predicted.
Published Quantum lidar prototype acquires real-time 3D images while fully submerged underwater



Researchers have demonstrated a prototype lidar system that uses quantum detection technology to acquire 3D images while submerged underwater. The high sensitivity of this system could allow it to capture detailed information even in extremely low-light conditions found underwater.
Published The future of data storage lies in DNA microcapsules



Storing data in DNA sounds like science fiction, yet it lies in the near future. Experts expect the first DNA data center to be up and running within five to ten years. Data won't be stored as zeros and ones in a hard drive but in the base pairs that make up DNA: AT and CG. Such a data center would take the form of a lab, many times smaller than the ones today.
Published 'Gluing' soft materials without glue



If you're a fan of arts and crafts, you're likely familiar with the messy, sticky, frustration-inducing nature of liquid glues. But researchers now have a brand-new way to weld squishy stuff together without the need for glue at all. They've demonstrated a universal, 'electroadhesion' technique that can adhere soft materials to each other just by running electricity through them.
Published Deep neural network provides robust detection of disease biomarkers in real time



A lab has developed a deep neural network that improves the accuracy of their unique devices for detecting pathogen biomarkers.
Published Highly dexterous robot hand can operate in the dark -- just like us



Researchers demonstrated a highly dexterous robot hand, one that combines an advanced sense of touch with motor learning algorithms in order to achieve a high level of dexterity. In addition, the hand worked without any external cameras -- it's immune to lighting, occlusion, or similar issues. Because the hand doesn't rely on vision to manipulate objects, it can do so in difficult lighting conditions that would confuse vision-based algorithms -- it even operates in the dark.
Published Unraveling the mathematics behind wiggly worm knots



Researchers wanted to understand precisely how blackworms execute tangling and ultrafast untangling movements for a myriad of biological functions. They researched the topology of the tangles. Their research could inform the design of fiber-like, shapeshifting robotics that self-assemble and move in ways that are fast and reversible.
Published Speedy robo-gripper reflexively organizes cluttered spaces



A new gripper robot grasps by reflex. Rather than start from scratch after a failed attempt, the bot adapts in the moment to reflexively roll, palm, or pinch an object to get a better hold.
Published How a horse whisperer can help engineers build better robots



New research shows us that age-old interactions between people and their horses can teach us something about building robots designed to improve our lives.
Published Jellyfish-like robots could one day clean up the world's oceans



Roboticists have developed a jellyfish-inspired underwater robot with which they hope one day to collect waste from the bottom of the ocean. The almost noise-free prototype can trap objects underneath its body without physical contact, thereby enabling safe interactions in delicate environments such as coral reefs. Jellyfish-Bot could become an important tool for environmental remediation.
Published Vaccine printer could help vaccines reach more people



Researchers have designed a tabletop-sized vaccine printer that could be scaled up to produce hundreds of vaccine doses in a day and deployed anywhere vaccines are needed. The vaccine doses are contained within microneedle patches that can be stored long-term at room temperature and applied to the skin, avoiding the need for injections.
Published New programmable smart fabric responds to temperature and electricity



A new smart material is activated by both heat and electricity, making it the first ever to respond to two different stimuli.
Published ChatGPT is still no match for humans when it comes to accounting



ChatGPT faced off against students on accounting assessments. Students scored an overall average of 76.7%, compared to ChatGPT's score of 47.4%. On a 11.3% of questions, ChatGPT scored higher than the student average, doing particularly well on AIS and auditing. But the AI bot did worse on tax, financial, and managerial assessments, possibly because ChatGPT struggled with the mathematical processes required for the latter type.
Published Versatile, high-speed, and efficient crystal actuation with photothermally resonated natural vibrations



Mechanically responsive molecular crystals are extremely useful in soft robotics, which requires a versatile actuation technology. Crystals driven by the photothermal effect are particularly promising for achieving high-speed actuation. However, the response (bending) observed in these crystals is usually small. Now, scientists address this issue by inducing large resonated natural vibrations in anisole crystals with UV light illumination at the natural vibration frequency of the crystal.
Published Rock, paper, scissors: Searching for stronger nonlocality using quantum computers



In the quantum world particles can instantaneously know about each other's state, even when separated by large distances. This is known as nonlocality. Now, A research group has produced some interesting findings on the Hardy nonlocality that have important ramifications for understanding quantum mechanics and its potential applications in communications.
Published Team designs four-legged robotic system that can walk a balance beam



Researchers have designed a system that makes an off-the-shelf quadruped robot nimble enough to walk a narrow balance beam -- a feat that is likely the first of its kind.
