Published Game-changing high-performance semiconductor material could help slash heat emissions
(via sciencedaily.com) Researchers have engineered a material with the potential to dramatically cut the amount of heat power plants release into the atmosphere.
Published New model provides improved air-quality predictions in fire-prone areas
(via sciencedaily.com) Globally, wildfires are becoming more frequent and destructive, generating a significant amount of smoke that can be transported thousands of miles, driving the need for more accurate air pollution forecasts. Researchers have now developed a deep learning model that provides improved predictions of air quality in wildfire-prone areas and can differentiate between wildfires and non-wildfires.
Published The 'Rapunzel' virus: an evolutionary oddity
(via sciencedaily.com) Extremely long tail provides structural window into how bacteria-infecting viruses called phages assemble.
Published Cleaning up the atmosphere with quantum computing
(via sciencedaily.com) Practical carbon capture technologies are still in the early stages of development, with the most promising involving a class of compounds called amines that can chemically bind with carbon dioxide. Researchers now deploy an algorithm to study amine reactions through quantum computing. An existing quantum computer cab run the algorithm to find useful amine compounds for carbon capture more quickly, analyzing larger molecules and more complex reactions than a traditional computer can.
Published Microneedle-based drug delivery technique for plants
(via sciencedaily.com) The agriculture industry is under pressure to adopt sustainable and precise agricultural practices that enable more efficient use of resources due to worsening environmental conditions resulting from climate change, an ever-expanding human population, limited resources, and a shortage of arable land. As a result, developing delivery systems that efficiently distribute micronutrients, pesticides, and antibiotics in crops is crucial to ensuring high productivity and high-quality produce while minimising resource waste. However, current and standard practices for agrochemical application in plants are inefficient. These practices cause significant detrimental environmental side effects, such as water and soil contamination, biodiversity loss and degraded ecosystems; and public health concerns, such as respiratory problems, chemical exposure and food contamination.
Published Tech could help BC farmers reach customers, mitigate climate change impacts
(via sciencedaily.com) Technology exists that the BC government could leverage to help small farmers connect directly with consumers and also mitigate climate change impacts, say new findings.
Published Biological network in cells helps body adapt to stresses on health
(via sciencedaily.com) Scientists have done research that opens up a whole new world within our cells. Their study uncovers a vast network of interactions that assist cells in adjusting in real time to withstand stresses on our health.
Published Switching to hydrogen fuel could prolong the methane problem
(via sciencedaily.com) Hydrogen is often heralded as the clean fuel of the future, but new research suggests that leaky hydrogen infrastructure could end up increasing atmospheric methane levels, which would cause decades-long climate consequences.
Published Researchers find decaying biomass in Arctic rivers fuels more carbon export than previously thought
(via sciencedaily.com) A new study found that plants and small organisms in Arctic rivers could be responsible for more than half the particulate organic matter flowing to the Arctic Ocean. That's a significantly greater proportion than previously estimated, and it has implications for how much carbon gets sequestered in the ocean and how much moves into the atmosphere.
Published TurboID uncovers new meiotic proteins in Arabidopsis thaliana
(via sciencedaily.com) Meiotic recombination assures genetic variation during breeding. During meiotic prophase I, chromosomes are organized in a loop-base array by a proteinaceous structure called meiotic chromosome axis which is critical for meiotic recombination and genetically diverse gametes. An international research team reports the application of a TurboID (TbID)-based approach to identify proteins in proximity of meiotic chromosome axes in Arabidopsis thaliana. Not only known but also new meiotic proteins were uncovered.
Published Study shows how biodiversity of coral reefs around the world changes with depth
(via sciencedaily.com) Dramatic differences between shallow and mesophotic reefs stress the importance of studying--and conserving--these vital ecosystems along their entire depth gradient.
Published A quick new way to screen virus proteins for antibiotic properties
(via sciencedaily.com) A whole new world of antibiotics is waiting inside the viruses that infect bacteria. Scientists are making it easier to study them.

Published Arctic climate modelling too conservative
(via sciencedaily.com) Climate models used by the UN's IPCC and others to project climate change are not accurately reflecting what the Arctic's future will be, experts say.
Published Triggering bitter taste receptors could someday treat asthma, COPD
(via sciencedaily.com) Surprisingly, bitter taste receptors are not only located in the mouth, but also elsewhere in the body, including the airways. Activating those receptors opens up lung passageways, so they're a potential target for treating asthma or chronic obstructive pulmonary disease (COPD). Now, researchers report that they have designed a potent and selective compound that could lead the way to such therapies.
Published How to assemble a complete jaw
(via sciencedaily.com) The skeleton, tendons, and glands of a functional jaw all derive from the same population of stem cells, which arise from a cell population known as neural crest. To discover how these neural crest-derived cells know to make the right type of cell in the right location, researchers focused on a particular gene, Nr5a2, that was active in a region of the face that makes tendons and glands, but not skeleton. To understand the role of Nr5a2, the scientists created zebrafish lacking this gene. These mutant zebrafish generated excess cartilage and were missing tendons in their jaws.
Published Jewel beetles evolve to see new colors by duplicating their genes
(via sciencedaily.com) Jewel beetles are striking insects, easily recognized by their vivid colors and metallic sheen. New research investigated the complex evolutionary history of jewel beetles' vision.
Published Remarkable squirting mussels captured on film
(via sciencedaily.com) Researchers have observed a highly unusual behavior in the endangered freshwater mussel, Unio crassus. The jets disturb the river surface and attract fish. Mussel larvae in the jets can then attach to the gills of the fish and complete their metamorphosis into adults.
Published Existential threats to the iconic Nile River Delta
(via sciencedaily.com) Decades of poor environmental and water management turned the Nile River Delta from a unique ecological habitat in the Sahara to one of the largest polluted areas on the planet, with tens of millions of people and migrating birds at risk of exposure to water-borne contaminants.
Published Ozone pollution is linked with increased hospitalizations for cardiovascular disease
(via sciencedaily.com) New evidence shows that exceeding the World Health Organization (WHO) ozone limit is associated with substantial increases in hospital admissions for heart attack, heart failure and stroke. Even ozone levels below the WHO maximum were linked with worsened health.
