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 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 New programmable smart fabric responds to temperature and electricity
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 Two qudits fully entangled
(via sciencedaily.com) Original source Recently quantum computers started to work with more than just the zeros and ones we know from classical computers. Now a team demonstrates a way to efficiently create entanglement of such high-dimensional systems to enable more powerful calculations.
Published Even as temperatures rise, this hydrogel material keeps absorbing moisture
(via sciencedaily.com) Original source Engineers find the hydrogel polyethylene glycol (PEG) doubles its water absorption as temperatures climb from 25 to 50 C, and could be useful for passive cooling or water harvesting in warm climates.
Published Tiny biobattery with 100-year shelf life runs on bacteria
(via sciencedaily.com) Original source A tiny biobattery that could still work after 100 years has been developed.
Published Chemists propose ultrathin material for doubling solar cell efficiency
(via sciencedaily.com) Original source Researchers are studying radical new ways to improve solar power and provide more options for the industry to explore. Chemists are proposing to make solar cells using not silicon, but an abundantly available natural material called molybdenum disulfide. Using a creative combination of photoelectrochemical and spectroscopic techniques, the researchers conducted a series of experiments showing that extremely thin films of molybdenum disulfide display unprecedented charge carrier properties that could someday drastically improve solar technologies.
Published Team designs four-legged robotic system that can walk a balance beam
(via sciencedaily.com) Original source 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.
Published A neuromorphic visual sensor can recognize moving objects and predict their path
(via sciencedaily.com) Original source The new smart sensor uses embedded information to detect motion in a single video frame.
Published A solar hydrogen system that co-generates heat and oxygen
(via sciencedaily.com) Original source Researchers have built a pilot-scale solar reactor that produces usable heat and oxygen, in addition to generating hydrogen with unprecedented efficiency for its size.
Published Multi-compartment membranes for multicellular robots: Everybody needs some body
(via sciencedaily.com) Original source We typically think of robots as metal objects, filled with motors and circuits. But the field of molecular robotics is starting to change that. Like the formation of complex living organisms, molecular robots derive their form and functionality from assembled molecules stored in a single unit, i.e., a body. Yet manufacturing this body at the microscopic level is an engineering nightmare. Now, a team has created a simple workaround.
Published Microwaves advance solar-cell production and recycling
(via sciencedaily.com) Original source New technology advances solar-cell production and recycling. New microwave technology will improve the manufacture of solar cells and make them easier to recycle.
Published Processing data at the speed of light
(via sciencedaily.com) Original source Scientists have developed an extremely small and fast nano-excitonic transistor.
Published Gentle method allows for eco-friendly recycling of solar cells
(via sciencedaily.com) Original source By using a new method, precious metals can be efficiently recovered from thin-film solar cells. The method is also more environmentally friendly than previous methods of recycling and paves the way for more flexible and highly efficient solar cells.
Published Chemists redesign biological PHAs, 'dream' biodegradable plastics
(via sciencedaily.com) Original source They've been called 'dream' plastics: polyhydroxyalkanoates, or PHAs. Already the basis of a fledgling industry, they're a class of polymers naturally created by living microorganisms, or synthetically produced from biorenewable feedstocks. They're biodegradable in the ambient environment, including oceans and soil.
Published Research in Japan shows the way toward tactile and proximity sensing in large soft robots
(via sciencedaily.com) Original source To make human-robot interactions safer and more fruitful, robots should be capable of sensing their environment. In a recent study, researchers developed a novel robotic link with tactile and proximity sensing capabilities. Additionally, they created a simulation and learning framework that can be employed to train the robotic link to sense its environment. Their findings will pave the way to a future where humans and robots can operate harmoniously in close proximity.
Published It's all in the wrist: Energy-efficient robot hand learns how not to drop the ball
(via sciencedaily.com) Original source Researchers have designed a low-cost, energy-efficient robotic hand that can grasp a range of objects -- and not drop them -- using just the movement of its wrist and the feeling in its 'skin'.
Published Cities will need more resilient electricity networks to cope with extreme weather
(via sciencedaily.com) Original source Dense urban areas amplify the effects of higher temperatures, due to the phenomenon of heat islands in cities. This makes cities more vulnerable to extreme climate events. Large investments in the electricity network will be necessary to cool us down during heatwaves and keep us warm during cold snaps, according to a new study.
