Published Microbial comics: RNA as a common language, presented in extracellular speech-bubbles



Decoding the conversations between microbes of hypersaline environments reveals deep insights into the origins of complex life.
Published Imaging grain boundaries that impede lithium-ion migration in solid-state batteries



A research team has developed a new technique to image grain boundaries obstructing lithium-ion migration in solid-state batteries -- a promising type of next-generation battery.
Published AI-driven lab speeds catalysis research



Researchers have developed a 'self-driving' lab that uses artificial intelligence (AI) and automated systems to provide in-depth analyses of catalytic reactions used in chemical research and manufacturing. The new tool, called Fast-Cat, can provide more information in five days than is possible in six months of conventional testing.
Published Human stem cells coaxed to mimic the very early central nervous system



The first stem cell culture method that produces a full model of the early stages of the human central nervous system has been developed by a team of engineers and biologists.
Published Black carbon sensor could fill massive monitoring gaps



Black carbon is up to 25 times more hazardous to human health than other airborne particles of a similar size. Standard sensors are expensive and burdensome, resulting in sparse coverage in regions infamous for poor air quality, such as the greater Salt Lake City area. A University of Utah-led study found that a portable, more affordable sensor recorded black carbon concentrations as accurately as the most widely used instrument for monitoring black carbon in real time. The portable sensor could help expand an accurate observation network to establish disease risk and create effective public health policies.
Published A new theoretical development clarifies water's electronic structure



Scientists have decoded the electronic structure of water, opening up new perspectives for technological and environmental applications.
Published The mutual neutralization of hydronium and hydroxide



Researchers have been able to directly visualize the neutral products of the mutual neutralization of hydronium and hydroxide, and report three different product channels: two channels were attributed to a predominant electron-transfer mechanism, and a smaller channel was associated with proton transfer. The two-beam collision experiment is an important step toward understanding the quantum dynamics of this fundamental reaction.
Published Using mussels and silkworm cocoons to stop organ bleeding



A collaborative research team develops an absorbent multifunctional nanofiber adhesive hemostat based on a protein biomaterial.
Published UBC Okanagan researchers look to the past to improve construction sustainability



Researchers are revisiting old building practices -- the use of by-products and cast-offs -- as a way to improve building materials and sustainability of the trade. A technique known as rammed earth construction uses materials that are alternatives to cement and are often more readily available in the environment. One such alternative is wood fly ash, a by-product of pulp mills and coal-fired power plants.
Published Chemists synthesize unique anticancer molecules using novel approach



Nearly 30 years ago, scientists discovered a unique class of anticancer molecules in a family of bryozoans, a phylum of marine invertebrates found in tropical waters. The chemical structures of these molecules, which consist of a dense, highly complex knot of oxidized rings and nitrogen atoms, has attracted the interest of organic chemists worldwide, who aimed to recreate these structures from scratch in the laboratory. However, despite considerable effort, it has remained an elusive task. Until now, that is. A team of chemists has succeeded in synthesizing eight of the compounds for the first time using an approach that combines inventive chemical strategy with the latest technology in small molecule structure determination.
Published Damage to cell membranes causes cell aging



Researchers have discovered that damage to the cell membrane promotes cellular senescence, or cell aging.
Published A new vibrant blue pottery pigment with less cobalt



Whether ultramarine, cerulean, Egyptian or cobalt, blue pigments have colored artworks for centuries. Now, seemingly out of the blue, scientists have discovered a new blue pigment that uses less cobalt but still maintains a brilliant shine. Though something like this might only happen once in a blue moon, the cobalt-doped barium aluminosilicate colorant withstands the high temperatures found in a kiln and provides a bright color to glazed tiles.
Published Scientists can tell where a mouse is looking and located based on its neural activity



Researchers have paired a deep learning model with experimental data to 'decode' mouse neural activity. Using the method, they can accurately determine where a mouse is located within an open environment and which direction it is facing, just by looking at its neural firing patterns. Being able to decode neural activity could provide insight into the function and behavior of individual neurons or even entire brain regions.
Published Graphene research: Numerous products, no acute dangers found by study



Graphene is an enormously promising material. It consists of a single layer of carbon atoms arranged in a honeycomb pattern and has extraordinary properties: exceptional mechanical strength, flexibility, transparency and outstanding thermal and electrical conductivity. If the already two-dimensional material is spatially restricted even more, for example into a narrow ribbon, controllable quantum effects can be created. This could enable a wide range of applications, from vehicle construction and energy storage to quantum computing.
Published Scientists discover link between leaky gut and accelerated biological aging



A professor has demonstrated a connection between viral damage to the gut and premature biological aging.
Published An environmentally friendly way to turn seafood waste into value-added products



Reduce, reuse, recycle, and repurpose: These are all ways we can live more sustainably. One tricky aspect of recycling, though, is that sometimes the recycling process is chemically intensive, and this is the case for recycling one of the world's most abundant materials -- chitin. Researchers have tackled this problem and found a way to sustainably recover chitin from seafood waste.
Published Revolutionary breakthrough in solar energy: Most efficient QD solar cells



A research team has unveiled a novel ligand exchange technique that enables the synthesis of organic cation-based perovskite quantum dots (PQDs), ensuring exceptional stability while suppressing internal defects in the photoactive layer of solar cells.
Published New system triggers cellular waste disposal



Established treatments for cancer and other diseases often focus on inhibiting harmful enzymes to mitigate their effects. However, a more innovative approach has emerged: harnessing the cell's natural waste disposal system not just to deactivate but to entirely eradicate these proteins. Researchers have previously demonstrated the efficacy of this approach through two distinct methods. Now they unveil a third system capable of targeting and disposing of previously inaccessible proteins.
Published Engineering a coating for disease-free produce



Texas A&M researchers combine food-grade wax with essential oils to defend produce from bacteria.
Published It's the spin that makes the difference



Biomolecules such as amino acids and sugars occur in two mirror-image forms -- in all living organisms, however, only one is ever found. Why this is the case is still unclear. Researchers have now found evidence that the interplay between electric and magnetic fields could be at the origin of this phenomenon.
