Chemists have developed a catalytic process that turns the largest component of today's plastic waste stream, polyolefin plastic bags and bottles, into gases -- propylene and isobutylene -- that are the building blocks of polypropylene and other types of plastics. The process uses inexpensive solid catalysts that can be scaled...
Scientist’s method could give months’ warning of major earthquakes
The public could have days or months of warning about a major earthquake through identification of prior low-level tectonic unrest over large areas, according to research by scientists who analyzed two major quakes in Alaska and California.
To build a thriving electric vehicle market, prioritize equity and justice
When it comes to purchasing and using electric vehicles (EVs), housing- and income-related factors significantly shape perceptions and preferences among potential buyers, finds a new study. This research is among the first to examine both EV adoption and charging infrastructure through an equity lens coupled with state-of-the-art original survey data.
Bacteria able to overcome cost of vancomycin resistance in lab setting
Staphylococcus aureus has the potential to develop durable vancomycin resistance, according to a new study.
Number of fish species at risk of extinction fivefold higher than previous estimates, according to a new prediction
Researchers predict that 12.7% of marine teleost fish species are at risk of extinction, up fivefold from the International Union for Conservation of Nature's prior estimate of 2.5%. Their report includes nearly 5,000 species that did not receive an IUCN conservation status due to insufficient data.
Plant signaling pathways decoded
Using newly generated 'optogenetic' tobacco plants, research teams have investigated how plants process external signals.
Dogs understand words from soundboard buttons
A new study reveals that dogs trained with soundboard buttons can indeed comprehend specific words, producing contextually appropriate responses.
Bacterial cells transmit memories to offspring
Bacterial cells can 'remember' brief, temporary changes to their bodies and immediate surroundings, a new study has found. And, although these changes are not encoded in the cell's genetics, the cell still passes memories of them to its offspring -- for multiple generations.
Among Viking societies, Norway was much more violent than Denmark
A new study sheds light on how Viking Age societies in Norway and Denmark differed in their experiences with violence and the role social structures played in shaping those patterns.
Prioritizing the unexpected: New brain mechanism uncovered
Researchers have discovered how two brain areas, neocortex and thalamus, work together to detect discrepancies between what animals expect from their environment and actual events. These prediction errors are implemented by selective boosting of unexpected sensory information. These findings enhance our understanding of predictive processing in the brain and could...
