Published The metaverse can lead to better science
(via sciencedaily.com) Original source One researcher says we should look beyond the hype to see how virtual reality can make scientists more effective. But to realize the benefits, researchers must also plan well and avoid potential pitfalls.
Published Scientists propose revolution in complex systems modelling with quantum technologies
(via sciencedaily.com) Original source Scientists have made a significant advancement with quantum technologies that could transform complex systems modelling with an accurate and effective approach that requires significantly re-duced memory.
Published Medical 'microrobots' could one day treat bladder disease, other human illnesses
(via sciencedaily.com) Original source Engineers have designed a new class of 'microrobots' several times smaller than the width of a human hair that may be able to treat human illnesses like interstitial cystitis -- a painful bladder disease that affects millions of Americans.
Published Quantum matter breakthrough: Tuning density waves
(via sciencedaily.com) Original source Scientists have found a new way to create a crystalline structure called a 'density wave' in an atomic gas. The findings can help us better understand the behavior of quantum matter, one of the most complex problems in physics.
Published Researchers build bee robot that can twist
(via sciencedaily.com) Original source A robotic bee that can fly fully in all directions has been developed. With four wings made out of carbon fiber and mylar as well as four light-weight actuators to control each wing, the Bee++ prototype is the first to fly stably in all directions. That includes the tricky twisting motion known as yaw, with the Bee++ fully achieving the six degrees of free movement that a typical flying insect displays.
Published Wiring up quantum circuits with light
(via sciencedaily.com) Original source The number of qubits in superconducting quantum computers has risen rapidly during the last years, but further growth is limited by the need for ultra-cold operating temperatures. Connecting several smaller processors could create larger, more computationally powerful quantum computers -- however doing so poses new challenges. Researchers have now demonstrated quantum entanglement between optical and microwave photons that could lay the foundation for such a future quantum network.
Published Robotic proxy brings remote users to life in real time
(via sciencedaily.com) Original source 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 A cocktail party of 3D-printed robot heads
(via sciencedaily.com) Original source Imagine a cocktail party full of 3D-printed, humanoid robots listening and talking to each other. That seemingly sci-fi scene is the goal of an augmented listening laboratory. With precise control over the simulated subjects, the researchers can adjust the parameters of the experiment and even set the machines in motion to simulate neck movements.
Published Scurrying centipedes inspire many-legged robots that can traverse difficult landscapes
(via sciencedaily.com) Original source 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 The future of data storage lies in DNA microcapsules
(via sciencedaily.com) Original source 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 A touch-responsive fabric armband -- for flexible keyboards, wearable sketchpads
(via sciencedaily.com) Original source It's time to roll up your sleeves for the next advance in wearable technology -- a fabric armband that's actually a touch pad. Researchers say they have devised a way to make playing video games, sketching cartoons and signing documents easier. Their proof-of-concept silk armband turns a person's forearm into a keyboard or sketchpad. The three-layer, touch-responsive material interprets what a user draws or types and converts it into images on a computer.
Published Self-folding origami machines powered by chemical reaction
(via sciencedaily.com) Original source Scientists have harnessed chemical reactions to make microscale origami machines self-fold -- freeing them from the liquids in which they usually function, so they can operate in dry environments and at room temperature.
Published Quantum entanglement of photons doubles microscope resolution
(via sciencedaily.com) Original source Using a "spooky" phenomenon of quantum physics, researchers have discovered a way to double the resolution of light microscopes.
Published Sensor enables high-fidelity input from everyday objects, human body
(via sciencedaily.com) Original source Couches, tables, sleeves and more can turn into a high-fidelity input device for computers using a new sensing system.
Published Speedy robo-gripper reflexively organizes cluttered spaces
(via sciencedaily.com) Original source 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 Tunneling electrons
(via sciencedaily.com) Original source By superimposing two laser fields of different strengths and frequency, the electron emission of metals can be measured and controlled precisely to a few attoseconds. Physicists have shown that this is the case. The findings could lead to new quantum-mechanical insights and enable electronic circuits that are a million times faster than today.
Published How a horse whisperer can help engineers build better robots
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 Cheaper method for making woven displays and smart fabrics -- of any size or shape
(via sciencedaily.com) Original source Researchers have developed next-generation smart textiles -- incorporating LEDs, sensors, energy harvesting, and storage -- that can be produced inexpensively, in any shape or size, using the same machines used to make the clothing we wear every day.
Published Nanowire networks learn and remember like a human brain
(via sciencedaily.com) Original source Scientists have demonstrated nanowire networks can exhibit both short- and long-term memory like the human brain.
