Monsoons are continental weather events produced when intense summer sunlight heats land more than ocean. But new supercomputer simulations show that North America's only monsoon works differently. The North American monsoon, which drenches western Mexico and the American Southwest each summer, is generated when the jet stream collides with the...
As LA traffic slowed amid the pandemic, researchers gained new insight into air pollution
Car tailpipes spew out molecules of ammonia, a harmful air pollutant that can lead to thousands of premature deaths every year. New research shows that vehicles may produce a lot more of these emissions than federal and state regulators have believed.
Holistic framework can assess fisheries’ strengths and potential weaknesses
A new decision-making framework designed by an international team of fisheries researchers can help fisheries bolster their ability to adapt to a warming world. The tool is meant to take a lot of the guesswork out of finding resilience in a time of climate change.
Extraordinary Roman mosaic and villa discovered beneath farmer’s field in Rutland, UK
Archaeologists have unearthed the first Roman mosaic of its kind in the UK.
Strong winds power electric fields in the upper atmosphere
Using observations from NASA's ICON mission, scientists presented the first direct measurements of Earth's long-theorized dynamo on the edge of space: a wind-driven electrical generator that spans the globe 60-plus miles above our heads. The dynamo churns in the ionosphere, the electrically charged boundary between Earth and space. It's powered...
Farmers spread Transeurasian languages
New research provides interdisciplinary support for the 'Farming Hypothesis' of language dispersal, tracing Transeurasian languages back to the first farmers moving across Northeast Asia beginning in the Early Neolithic -- roughly between 8-10 thousand years ago.
Eight worst wildfire weather years on record happened in the last decade
The world's eight most extreme wildfire weather years on record have occurred in the last decade, according to a new study that suggests extreme weather is being driven by a decrease in atmospheric humidity coupled with rising temperatures.
Potential new therapeutic pathway to clear chronic viral infections
A recent study in mice has uncovered that during chronic viral infection, a protein called BMI-1 gets turned on too early in B cells and messes up the delicate balance of gene expression, resulting in antibodies that are unsuccessful in their endeavor to clear the virus from the body.
Nibbling prehistoric herbivore sheds new light on Triassic diversity
A Triassic herbivore, known for its supposed similarities to a modern-day ostrich, has been revealed to have entirely different approach to feeding from previously thought.
Researchers identify behavioral adaptations that may help Antarctic fishes adapt to warming Southern Ocean
Scientists describe how Antarctic fishes with and without hemoglobin react to acute thermal stress. The responses may help the fish withstand the impacts of climate change.
