Published Advancing modular quantum information processing
(via sciencedaily.com) Original source A team of physicists envisions a modular system for scaling quantum processors with a flexible way of linking qubits over long distances to enable them to work in concert to perform quantum operations. The ability to carry out such correlated or 'entangling' operations between linked qubits is the basis of the enhanced power quantum computing holds compared with current computers.
Published New brain-computer interface allows man with ALS to 'speak' again
(via sciencedaily.com) Original source A new brain-computer interface translates brain signals into speech with up to 97 percent accuracy. Researchers implanted sensors in the brain of a man with severely impaired speech due to amyotrophic lateral sclerosis (ALS). The man was able to communicate his intended speech within minutes of activating the system.
Published Smart fabric converts body heat into electricity
(via sciencedaily.com) Original source Researchers have developed a smart fabric that can convert body heat and solar energy into electricity, potentially enabling continuous operation with no need for an external power source. Different sensors monitoring temperature, stress, and more can be integrated into the material.
Published How air-powered computers can prevent blood clots
(via sciencedaily.com) Original source A new, air-powered computer sets off alarms when certain medical devices fail. The invention is a more reliable and lower-cost way to help prevent blood clots and strokes -- all without electronic sensors.
Published In subdivided communities cooperative norms evolve more easily
(via sciencedaily.com) Original source Researchers simulated social norms with a supercomputer. Their findings contribute to a deeper understanding of the evolution of social norms and their role in fostering cooperative behavior.
Published Say 'aah' and get a diagnosis on the spot: is this the future of health?
(via sciencedaily.com) Original source A computer algorithm has achieved a 98% accuracy in predicting different diseases by analyzing the color of the human tongue. The proposed imaging system can diagnose diabetes, stroke, anemia, asthma, liver and gallbladder conditions, COVID-19, and a range of vascular and gastrointestinal issues, according to new research.
Published New method for orchestrating successful collaboration among robots
(via sciencedaily.com) Original source New research shows that programming robots to create their own teams and voluntarily wait for their teammates results in faster task completion, with the potential to improve manufacturing, agriculture and warehouse automation.
Published Engineers make tunable, shape-changing metamaterial inspired by vintage toys
(via sciencedaily.com) Original source Common push puppet toys in the shapes of animals and popular figures can move or collapse with the push of a button at the bottom of the toys' base. Now, a team of engineers has created a new class of tunable dynamic material that mimics the inner workings of push puppets, with applications for soft robotics, reconfigurable architectures and space engineering.
Published Wearable display tech: Full-color fiber LEDs based on perovskite quantum wires
(via sciencedaily.com) Original source A research team has developed full-color fiber light-emitting diodes utilizing perovskite quantum wires (PeQWs), paving the way for innovative wearable lighting and display devices.
Published Redefining the computer whiz: Research shows diverse skills valued by youth
(via sciencedaily.com) Original source Researchers have uncovered a more nuanced view of what makes an 'ideal' computer science student, challenging long-held stereotypes of geeky, clever, detail-oriented men, who lack social skills.
Published From doom-scrolling to mindfulness
(via sciencedaily.com) Original source Researchers have created Mindful Scroll, a mobile app that helps users transition from doom-scrolling to adding mindfulness into their daily routines.
Published New mechanism to cool buildings while saving energy
(via sciencedaily.com) Original source The movement of radiant heat -- felt when a hot surface warms our bodies and homes -- between buildings and their surroundings at ground level makes buildings with less skyward-facing surfaces harder to cool. A research team has demonstrated a new passive cooling technology that coats walls and windows with materials that can better manage heat movement between buildings and their surroundings at ground level. Findings could reduce the reliance on air conditioning and provide a more environmentally friendly, low-cost and scalable option for low-income communities with limited or no access to cooling and heating systems.
Published New technology uses light to engrave erasable 3D images
(via sciencedaily.com) Original source Researchers invented a technique that uses a specialized light projector and a photosensitive chemical additive to imprint two- and three-dimensional images inside any polymer. The light-based engraving remains in the polymer until heat or light are applied, which erases the image and makes it ready to use again. The technology is intended for any situation where having detailed, precise visual data in a compact and easily customizable format could be critical, such as planning surgeries and developing architectural designs.
Published Turning unused signals such as Wi-Fi into energy for electronics
(via sciencedaily.com) Original source We are constantly surrounded by electromagnetic waves such as Wi-Fi. Researchers tested a device to convert this ambient energy into energy for electronic devices.
Published Researchers solve long-standing challenge for piezoelectric materials
(via sciencedaily.com) Original source Heat and pressure can deteriorate the properties of piezoelectric materials that make state-of-the-art ultrasound and sonar technologies possible -- and fixing that damage has historically required disassembling devices and exposing the materials to even higher temperatures. Now researchers have developed a technique to restore those properties at room temperature, making it easier to repair these devices -- and paving the way for new ultrasound technologies.
Published Heating for fusion: Why toast plasma when you can microwave it!
(via sciencedaily.com) Original source Can plasma be sufficiently heated inside a tokamak using only microwaves? New research suggests it can! Eliminating the central ohmic heating coil normally used in tokamaks will free up much-needed space for a more compact, efficient spherical tokamak.
Published AI for mental health screening may carry biases based on gender, race
(via sciencedaily.com) Original source A growing body of AI tools screen how people talk, searching for subtle changes that could indicate mental health concerns like depression or anxiety. A study finds that these tools don't perform consistently across people from different genders and races.
Published Revolutionary loop heat pipe transports 10 kW of waste heat -- No electricity required
(via sciencedaily.com) Original source Researchers have unveiled a new loop heat pipe capable of transporting up to 10 kW of heat without using electric power. The loop heat pipe's design aims to contribute to energy savings and carbon neutrality in various fields, including waste heat recovery, solar heat utilization, electric vehicle thermal management, and data center cooling.
