Published Tiny yet hazardous: New study shows aerosols produced by contaminated bubble bursting are far smaller than predicted
(via sciencedaily.com) New research has shown that bursting bubbles coated by a thin oil layer produce drops with smaller sizes, greater overall number of drops, and are ejected at a higher velocity, compared to bubbles generated in clean water.
Published Advanced electrode to help remediation of stubborn new 'forever chemicals'
(via sciencedaily.com) As new environmental regulations are rolling out to mitigate the industry-retired long-chain chemicals known as PFAS in drinking water, there are concerns regarding a new breed of 'forever chemicals' called short-chain PFAS. Research is now helping shift the focus to include mitigation of the chemicals -- which researchers say are just as persistent as, more mobile and harder to remove from the environment than their long-chain counterparts.
Published Nanophysics: The right twist
(via sciencedaily.com) Stacked layers of ultrathin semiconductor materials feature phenomena that can be exploited for novel applications. Physicists have studied effects that emerge by giving two layers a slight twist.
Published New ways to measure curls and kinks could make it easier to care for natural hair
(via sciencedaily.com) Black women and others with curly or kinky hair encounter a confusing array of haircare options. Advice on the best products to use for a certain type of hair is often contradictory, and the results can be highly variable. Now, scientists are bringing order to this chaos by identifying hair properties that could help users pick the perfect product and achieve consistent results.
Published Meet the hybrid micro-robot: The tiny robot that is able to navigate in a physiological environment and capture targeted damaged cells
(via sciencedaily.com) Researchers have developed a hybrid micro-robot, the size of a single biological cell (about 10 microns across), that can be controlled and navigated using two different mechanisms -- electric and magnetic. The micro-robot is able to navigate between different cells in a biological sample, distinguish between different types of cells, identify whether they are healthy or dying, and then transport the desired cell for further study, such as genetic analysis.
Published Surprise effect: Methane cools even as it heats
(via sciencedaily.com) Most climate models do not yet account for a recent discovery: methane traps a great deal of heat in Earth's atmosphere, but also creates cooling clouds that offset 30% of the heat.
Published New type of entanglement lets scientists 'see' inside nuclei
(via sciencedaily.com) Nuclear physicists have found a new way to see inside nuclei by tracking interactions between particles of light and gluons. The method relies on harnessing a new type of quantum interference between two dissimilar particles. Tracking how these entangled particles emerge from the interactions lets scientists map out the arrangement of gluons. This approach is unusual for making use of entanglement between dissimilar particles -- something rare in quantum studies.
Published Photosynthesis: Varying roads lead to the reaction center
(via sciencedaily.com) Chemists use high-precision quantum chemistry to study key elements of super-efficient energy transfer in an important element of photosynthesis.
Published AI 'brain' created from core materials for OLED TVs
(via sciencedaily.com) A research team develops semiconductor devices for high-performance AI operations by applying IGZO materials widely used in OLED displays.
Published Microplastics limit energy production in tiny freshwater species
(via sciencedaily.com) Microplastic pollution reduces energy production in a microscopic creature found in freshwater worldwide, new research shows.
Published At least 80% of the world's most important sites for biodiversity on land currently contain human developments
(via sciencedaily.com) At least 80% of sites identified as being internationally important for biodiversity on land currently contain infrastructure -- of which more than 75% contain roads. In the future, more sites that are important for biodiversity could contain powerplants, mines and oil and gas infrastructure.
Published Closed loop for circular economy: New polymer recycling strategy ensures both high stability and complete recyclability
(via sciencedaily.com) Large amounts of plastic waste are incinerated or deposited in landfills. This degrades the environment and depletes valuable resources. In this light, recycling plastics such as polymers is promising. However, recycling diminishes their quality. Recently, researchers have proposed a 'closed-loop' recycling process based on polymer microparticles. It produces fully recyclable polymer films with high mechanical stability and fracture energy, which they retain upon recycling.
Published New wood-based technology removes 80% of dye pollutants in wastewater
(via sciencedaily.com) Researchers have developed a new method that can easily purify contaminated water using a cellulose-based material. This discovery could have implications for countries with poor water treatment technologies and combat the widespread problem of toxic dye discharge from the textile industry.
Published Genome of a drought-tolerant plant: Many genes are involved in 'resurrection'
(via sciencedaily.com) Some plants can survive months without water, only to turn green again after a brief downpour. A recent study shows that this is not due to a 'miracle gene.' Rather, this ability is a consequence of a whole network of genes, almost all of which are also present in more vulnerable varieties.
Published Visualizing spatial distribution of electric properties at microscales with liquid crystal droplets
(via sciencedaily.com) Existing sensor probes for microelectrical devices can measure only their average electric properties, providing no information on their spatial distribution. Liquid crystal droplets (LCDs) -- microscopic droplets of soft matter that respond to electric field -- are promising in this regard. Accordingly, researchers recently visualized the electric field and electrostatic energy distribution of microstructured electrodes by recording the motion of LCDs under an applied voltage, making for high detection accuracy and spatial resolution.
Published Phytoplankton blooms offer insight into impacts of climate change
(via sciencedaily.com) The first study into the biological response of the upper ocean in the wake of South Pacific cyclones could help predict the impact of warming ocean temperatures, researchers believe.
Published Tackling counterfeit seeds with 'unclonable' labels
(via sciencedaily.com) As a way to reduce seed counterfeiting, researchers developed a silk-based tag that, when applied to seeds, provides a unique code that cannot be duplicated.
Published Researchers create artificial enzyme for fast detection of disease-related hormone in sweat
(via sciencedaily.com) Researchers have developed a handheld sensor that tests perspiration for cortisol and provides results in eight minutes, a key advance in monitoring a hormone whose levels are a marker for many illnesses including various cancers.
Published New water treatment zaps 'forever chemicals' for good
(via sciencedaily.com) Engineers have developed a new water treatment that removes 'forever chemicals' from drinking water safely, efficiently -- and for good.
Published Photosynthesis 'hack' could lead to new ways of generating renewable energy
(via sciencedaily.com) Researchers have 'hacked' the earliest stages of photosynthesis, the natural machine that powers the vast majority of life on Earth, and discovered new ways to extract energy from the process, a finding that could lead to new ways of generating clean fuel and renewable energy.
