Published Polymeric films protect anodes from sulfide solid electrolytes
(via sciencedaily.com) Original source Researchers unveil the interaction between polymeric materials and sulfide solid electrolytes.
Published Harnessing green energy from plants depends on their circadian rhythms
(via sciencedaily.com) Original source Plant hydraulics drive the biological process that moves fluids from roots to plant stems and leaves, creating streaming electric potential, or voltage, in the process. A study closely examined the differences in voltage caused by the concentrations of ions, types of ions, and pH of the fluid plants transport, tying the voltage changes to the plant's circadian rhythm that causes adjustments day and night. According to the authors, this consistent, cyclic voltage creation could be harnessed as an energy source.
Published Global activity of seafloor biodiversity mapped
(via sciencedaily.com) Original source A team of scientists has used artificial intelligence (AI) to map the activities of seafloor invertebrate animals, such as worms, clams and shrimps, across all the oceans of the world.
Published 'Invisible tweezers' use robotics and acoustic energy to achieve what human hands cannot
(via sciencedaily.com) Original source Undergoing surgery is seldom a pleasant experience, and it can sometimes be highly invasive. Surgical procedures have evolved steadily over the centuries, growing with the knowledge of anatomy and biology. Innovative methods have also been bolstered with new tools, and a growth in the use of robotics since the 1980s has moved health care forward significantly.
Published Controlling water, transforming greenhouse gases
(via sciencedaily.com) Original source Researchers have outlined a way to manipulate water molecules to make CO2R more efficient, with the ultimate goal of creating a clean energy loop. Through their new method, the team was able to perform CO2R with nearly 100% efficiency under mildly acidic conditions, using either gold or zinc as catalysts.
Published Observing mammalian cells with superfast soft X-rays
(via sciencedaily.com) Original source Researchers have developed a new technique to view living mammalian cells. The team used a powerful laser, called a soft X-ray free electron laser, to emit ultrafast pulses of illumination at the speed of femtoseconds, or quadrillionths of a second. With this they could capture images of carbon-based structures in living cells for the first time, before the soft X-ray radiation damaged them.
Published Charting a pathway to next-gen biofuels
(via sciencedaily.com) Original source From soil to sequestration, researchers have modeled what a supply chain for second-generation biofuels might look like in the midwestern United States.
Published Team enhances stereotactic neurosurgery precision using MRI-guided multi-stage robotic positioner
(via sciencedaily.com) Original source A research team developed an interactive multi-stage robotic positioner specifically designed for magnetic resonance imaging (MRI)-guided stereotactic neurosurgery.
Published Producing novel liquid crystals by stacking antiaromatic units
(via sciencedaily.com) Original source In a recent study, researchers developed modified norcorrole molecules whose side chains favored the formation of columnar -stacking structures. Using these compounds, they produced liquid crystals with high electrical conductivity and thermotropic properties. Their findings open up new design avenues for materials useful in electronics, sensing, optics, and biomedicine.
Published Sexual parasitism helped anglerfish invade the deep sea during a time of global warming
(via sciencedaily.com) Original source Members of the vertebrate group including anglerfishes are unique in possessing a characteristic known as sexual parasitism, in which males temporarily attach or permanently fuse with females to mate. Now, researchers show that sexual parasitism arose during a time of major global warming and rapid transition for anglerfishes from the ocean floor to the deep, open sea.
Published Future climate impacts put whale diet at risk
(via sciencedaily.com) Original source A new study predicts future climate change impacts could disrupt the krill-heavy diet that humpback whales in the southern hemisphere consume.
Published Wearable devices get signal boost from innovative material
(via sciencedaily.com) Original source An international team have developed a new material that moves like skin while preserving signal strength in electronics. The technology could enable the development of next-generation wearable devices with continuous, consistent wireless and battery-free functionality.
Published Beach erosion will make Southern California coastal living five times more expensive by 2050, study predicts
(via sciencedaily.com) Original source Southern California's iconic sandy coastlines are vanishing at an alarming rate, and it's a warning sign for coastal communities worldwide, new research suggests.
Published Wearable ultrasound patch enables continuous, non-invasive monitoring of cerebral blood flow
(via sciencedaily.com) Original source Engineers have developed a wearable ultrasound patch that can offer continuous, non-invasive monitoring of blood flow in the brain. The soft and stretchy patch can be comfortably worn on the temple to provide three-dimensional data on cerebral blood flow--a first in wearable technology.
Published Scientists learn how to control muscles with light
(via sciencedaily.com) Original source Researchers developed a way to help people with amputation or paralysis regain limb control. Their optogenetic technique could offer more precise control over muscle contraction, along with a dramatic decrease in muscle fatigue.
Published Researchers design new metal-free porous framework materials
(via sciencedaily.com) Original source Researchers have used computational design methods to develop non-metal organic porous framework materials, with potential applications in areas such as catalysis, water capture or hydrogen storage.
Published Adhesive coatings can prevent scarring around medical implants
(via sciencedaily.com) Original source Engineers have found a way to eliminate the buildup of scar tissue around implantable devices, by coating them with a hydrogel adhesive. The material binds the device to tissue and prevents the immune system from attacking the device.
Published Promethium bound: Rare earth element's secrets exposed
(via sciencedaily.com) Original source Scientists have uncovered the properties of a rare earth element that was first discovered 80 years ago at the very same laboratory, opening a new pathway for the exploration of elements critical in modern technology, from medicine to space travel.
Published Scientists develop new battery-free lactic acid sensor
(via sciencedaily.com) Original source Scientists have created a new type of chemosensor (demonstrated for lactic acid sensing) which functions with electricity but without the need for reference electrodes or battery power.
Published Flexible film senses nearby movements -- featured in blink-tracking glasses
(via sciencedaily.com) Original source I'm not touching you! When another person's finger hovers over your skin, you may get the sense that they're touching you, feeling not necessarily contact, but their proximity. Similarly, researchers have designed a soft, flexible film that senses the presence of nearby objects without physically touching them. The study features the new sensor technology to detect eyelash proximity in blink-tracking glasses.
