Published Novel, highly sensitive biosensor set to transform wearable health monitoring
(via sciencedaily.com) Original source Wearable wireless biosensors are an integral part of digital healthcare and monitoring. Commonly used chipless resonant antenna-based biosensors are simple and affordable, but have limited applicability due to their low sensitivity. Now, researchers have developed a novel, wireless, parity-time symmetry-based bioresonator that can detect minute concentrations of tear glucose and blood lactate. This highly sensitive, tunable, and robust bioresonator has the potential to revolutionize personalized health monitoring and digitized healthcare systems.
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 Recovering rare earth elements in environmental water
(via sciencedaily.com) Original source A research group has succeeded in selectively recovering trace rare earth elements in synthetic seawater and environmental water, such as hot spring water, using baker's yeast with a phosphate group added. The phosphorylated yeast is expected to be utilized as a material for recovering useful metals and removing toxic metals, thereby contributing to the realization of a metal resource-circulating society.
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 Healing the unhealable: New approach helps bones mend themselves
(via sciencedaily.com) Original source Young babies and newborn mice can naturally heal damage to the bones that form the top of the skull, but this ability is lost in adults. Researchers developed a novel approach that promoted bone regeneration in mice without implantation of bone tissue or biomaterials.
Published Laser light hybrids control giant currents at ultrafast times
(via sciencedaily.com) Original source The flow of matter, from macroscopic water currents to the microscopic flow of electric charge, underpins much of the infrastructure of modern times. In the search for breakthroughs in energy efficiency, data storage capacity, and processing speed, scientists search for ways in which to control the flow of quantum aspects of matter such as the 'spin' of an electron -- its magnetic moment -- or its 'valley state', a novel quantum aspect of matter found in many two dimensional materials. A team of researchers has recently discovered a route to induce and control the flow of spin and valley currents at ultrafast times with specially designed laser pulses, offering a new perspective on the ongoing search for the next generation of information technologies.
Published Engineers devise technology to prevent fouling in photobioreactors for CO2 capture
(via sciencedaily.com) Original source A new, inexpensive technology can limit the buildup of algae on the walls of photobioreactors that can help convert carbon dioxide into useful products. Reducing this fouling avoids costly cleanouts and allows more photosynthesis to happen within tanks.
Published Students engineer socks for on-the-go neuropathy treatment
(via sciencedaily.com) Original source A wearable electrical-stimulation and vibration-therapy system designed by engineering students might be just what the doctor ordered for people experiencing foot pain and balance loss due to diabetic neuropathy.
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 Testing vaccine candidates quickly with lab-grown mini-organs
(via sciencedaily.com) Original source Developing and testing new treatments or vaccines for humans almost always requires animal trials, but these experiments can sometimes take years to complete and can raise ethical concerns about the animals' treatment. Now, researchers reporting in ACS Central Science have developed a new testing platform that encapsulates B cells -- some of the most important components of the immune system -- into miniature 'organoids' to make vaccine screening quicker and greatly reduce the number of animals needed.
Published Increased droughts are disrupting carbon-capturing soil microbes, concerning ecologists
(via sciencedaily.com) Original source Soil stores more carbon than plants and the atmosphere combined, and soil microbes are largely responsible for putting it there. However, the increasing frequency and severity of drought, such as those that have been impacting California, could disrupt this delicate ecosystem. Microbial ecologists warn that soil health and future greenhouse gas levels could be impacted if soil microbes adapt to drought faster than plants do.
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 Pollution monitoring through precise detection of gold nanoparticles in woodlice
(via sciencedaily.com) Original source Researchers introduce a novel imaging method to detect gold nanoparticles in woodlice. Their method, known as four-wave mixing microscopy, flashes light that the gold nanoparticles absorb. The light flashes again and the subsequent scattering reveals the nanoparticles' locations. With information about the quantity, location, and impact of gold nanoparticles within the organism, scientists can better understand the potential harm other metals may have on nature.
Published Table tennis brain teaser: Playing against robots makes our brains work harder
(via sciencedaily.com) Original source Brain scans taken during table tennis reveal differences in how we respond to human versus machine opponents.
Published Shutting down nuclear power could increase air pollution
(via sciencedaily.com) Original source A new study shows that if U.S. nuclear power plants are retired, the burning of coal, oil, and natural gas to fill the energy gap could cause more than 5,000 premature deaths.
Published Solar cells charging forward
(via sciencedaily.com) Original source An environmentally friendlier solution to solar cell production with enhanced performance utilizes PEDOT:PSS/silicon heterojunction solar cells. This hybrid type is made of organic-inorganic material, which could potentially ease the production process compared to conventional silicon-only solar cells. It avoids manufacturing solar cells in vacuums and high-temperature processes, which require large and expensive equipment and a great amount of time.
