Published How scientists are accelerating chemistry discoveries with automation
(via sciencedaily.com) Original source Scientists have developed an automated workflow that could accelerate the discovery of new pharmaceutical drugs and other useful products. The new automated approach could analyze chemical reactions in real time and identify new chemical-reaction products much faster than current laboratory methods.
Published Innovative sensing platform unlocks ultrahigh sensitivity in conventional sensors
(via sciencedaily.com) Original source Engineers unlock the power of exceptional points (EPs) for advanced optical sensing. EPs -- specific conditions in systems where extraordinary optical phenomena can occur -- can be deployed on conventional sensors to achieve a striking sensitivity to environmental perturbations.
Published Dinosaur study challenges Bergmann's rule
(via sciencedaily.com) Original source A new study calls into question Bergmann's rule, an 1800s-era scientific principle stating that animals in high-latitude, cooler climates tend to be larger than close relatives living in warmer climates.
Published eDNA methods give a real-time look at coral reef health
(via sciencedaily.com) Original source The study underscores the crucial role of microbes in maintaining coral reef health, akin to the human gut microbiome. Hurricanes and disease outbreaks affect coral reef water microbial communities, leading to changes that may support further reef decline. Microbial analysis enables prompt assessment of disturbances' impacts on coral reefs, facilitating timely interventions to support reef ecosystems. Environmental DNA (eDNA) analysis offers a noninvasive approach to study coral microbial communities and diagnose reef health.
Published Chemical reactions can scramble quantum information as well as black holes
(via sciencedaily.com) Original source A team of researchers has shown that molecules can be as formidable at scrambling quantum information as black holes by combining mathematical tools from black hole physics and chemical physics and testing their theory in chemical reactions.
Published Four in five bird species cannot tolerate intense human pressures
(via sciencedaily.com) Original source In a recent study, researchers found that 78% of the world's bird species do not thrive in the most modified human-dominated environments. These species are also most likely to have declining populations.
Published Ocean floor a 'reservoir' of plastic pollution
(via sciencedaily.com) Original source New science has taken a deep dive into plastic waste, providing the first estimate of how much ends up on the sea floor.
Published What four decades of canned salmon reveal about marine food webs
(via sciencedaily.com) Original source Researchers have shown that levels of anisakid worms -- a common marine parasite -- rose in two salmon species in the Gulf of Alaska and Bristol Bay over a 42-year period. The team discovered this by studying salmon caught, killed and canned from 1979 to 2021. Since anisakid worms have a complex life cycle involving multiple types of hosts, the researchers interpret their rising numbers as a potential sign of ecosystem recovery, possibly driven by rising numbers of marine mammals thanks to the 1972 Marine Mammal Protection Act.
Published 'Diverse' agriculture benefits people and the environment at the same time
(via sciencedaily.com) Original source A new analysis from 2,655 farms on five continents suggests that moving away from industrial, monoculture farming could benefit both the planet and people.
Published Shy sea anemones are more likely to survive heatwaves
(via sciencedaily.com) Original source A study shows that sea anemones that react more slowly to change can survive a heatwave better than individuals that change their behavior quickly.
Published Self-assembly of complex systems: Hexagonal building blocks are better
(via sciencedaily.com) Original source Physicists show that the shape of components is a major determinant of how quickly and efficiently complex structures self-assemble.
Published Out of the park: New research tallies total carbon impact of tourism at Yellowstone
(via sciencedaily.com) Original source New research makes a case study of Yellowstone National Park -- calculating surplus carbon that visitors from across the world add to the atmosphere each year as a direct result of a park visit.
Published 'Tug of war' tactic enhances chemical separations for critical materials
(via sciencedaily.com) Original source Lanthanide elements are important for clean energy and other applications. To use them, industry must separate mixed lanthanide sources into individual elements using costly, time-consuming, and waste-generating procedures. An efficient new method can be tailored to select specific lanthanides. The technique combines two substances that do not mix and that prefer different types of lanthanides. The process would allow for smaller equipment, less use of chemicals, and less waste production.
Published For mining in arid regions to be responsible, we must change how we think about water
(via sciencedaily.com) Original source In an unprecedented study of the South American 'Lithium Triangle,' hydrologists discover that not all water responds the same way to environmental change and human use.
Published Developing a vaccine for the 'zombie drug' xylazine
(via sciencedaily.com) Original source Chemical biologists design an early 'proof-of-concept' vaccine that could lead to the first effective treatment of xylazine overdose in people.
Published 'Smart swarms' of tiny robots inspired by natural herd mentality
(via sciencedaily.com) Original source Researchers gave nanorobots a trait called adaptive time delay, which allows them to better work together.
Published Machine learning enables viability of vertical-axis wind turbines
(via sciencedaily.com) Original source Researchers have used a genetic learning algorithm to identify optimal pitch profiles for the blades of vertical-axis wind turbines, which despite their high energy potential, have until now been vulnerable to strong gusts of wind.
Published Plant-based plastic releases nine times less microplastics than conventional plastic
(via sciencedaily.com) Original source A newly developed plant-based plastic material releases nine times less microplastics than conventional plastic when exposed to sunlight and seawater, a new study has found.
Published Drawing inspiration from plants: A metal-air paper battery for wearable devices
(via sciencedaily.com) Original source Drawing inspiration from the way plants breathe, a group of researchers has created a paper-based magnesium-air battery that can be used in GPS sensors or pulse oximeter sensors. Taking advantage of paper's recyclability and lightweight nature, the engineered battery holds promise for a more environmentally friendly source of energy.
Published Plastic-free vegan leather that dyes itself grown from bacteria
(via sciencedaily.com) Original source Researchers have genetically engineered bacteria to grow animal- and plastic-free leather that dyes itself.
