Researchers explain the importance of identifying and understanding how differences between tissues and cells alter gene expression without changing the underlying genetic code.
Norovirus and other ‘stomach viruses’ can spread through saliva
A class of viruses known to cause severe diarrheal diseases -- including the one famous for widespread outbreaks on cruise ships -- can grow in the salivary glands of mice and spread through their saliva, scientists have discovered. The findings show that a new route of transmission exists for these...
Underwater jars reveal Roman period winemaking practices
Winemaking practices in coastal Italy during the Roman period involved using native grapes for making wine in jars waterproofed with imported tar pitch, according to a new study.
Researchers identify the microbes in 100-year-old snail guts
The gut 'microbiomes' of long-dead animals could give researchers surprising insights into how climate change and other factors have shaped the Rocky Mountains and other ecosystems over decades.
Pollution exposure associated with multimorbidity risk
Exposure to the air pollution known as fine particulate matter (PM2.5) is associated with an increased risk of having a cluster of multiple chronic diseases, according to a new study.
Underground carnivore: the first species of pitcher plant to dine on subterranean prey
A remarkable new species of carnivorous plant was discovered in a remote part of Borneo. It is the first pitcher plant known to produce functional underground traps, and the first for which capture of subterranean prey has been observed. While the traps themselves are often a rich maroon colour, they...
Music is key to converting consumers’ good intentions to actual purchases in ethical and sustainable markets
Companies selling ethical and sustainable products should use up-tempo major mode music in their marketing to help well-meaning consumers convert their good intentions into actual purchases, new research shows.
Changes in oceanographic fronts affect the gene flow among marine crab populations
In the Mediterranean and the Atlantic, the intensity and location of the oceanographic fronts that limit the gene connectivity among populations of marine crabs vary over time. These dynamic changes alter the gene structure of the populations of marine crabs of commercial and gastronomic interest.
Chemicals in Fairbanks winter air
A chemical compound discovered in 2019 in Fairbanks' wintertime air accounts for a significant portion of the community's fine particulate pollution, according to new research that seeks to better understand the causes and makeup of the dirty air. The finding is the first measurement of how much hydroxymethanesulfonate, or HMS, is in...
Strategies beyond recycling to bolster circular economy for solar and battery technologies
In a new comprehensive literature review, researchers have discovered that alternatives to recycling may have untapped potential to build an effective circular economy for solar photovoltaic (PV) and battery technologies. These alternative strategies, such as reducing the use of virgin materials in manufacturing, reusing for new applications, and extending product...
