Phys.org / Adoption of electric vehicles tied to real-world reductions in air pollution
When California neighborhoods increased their number of zero-emissions vehicles (ZEV) between 2019 and 2023, they also experienced a reduction in air pollution. For every 200 vehicles added, nitrogen dioxide (NO₂) levels ...
Phys.org / Dark energy survey scientists release analysis of all six years of survey data
The Dark Energy Survey Collaboration collected information on hundreds of millions of galaxies across the universe using the U.S. Department of Energy-fabricated Dark Energy Camera, mounted on the U.S. National Science Foundation ...
Phys.org / Highly stable Cu₄₅ superatom could transform carbon recycling
After years of trying, scientists have finally created a stable superatom of copper, a long-sought-after chemical breakthrough that could revolutionize how we deal with carbon emissions.
Phys.org / Higher water levels could turn cultivated peatland in the North into a CO₂ sink
In its natural state, peatland is one of the largest carbon stores in nature. This is because the soil is so waterlogged and low in oxygen that dead plant material breaks down very slowly. The plants do not fully decompose ...
Phys.org / Chicago's Brookfield Zoo leads effort to protect polar bears as Trump opens Arctic refuge to oil drilling
Shortly after her arrival last fall, Amelia Gray met Hudson, and the pair hit it off immediately. They touched their noses together in greeting and chuffed—a soft, breathy, snorting sound that signals affection or reassurance. ...
Phys.org / Engineering and the quest for peace: Experts challenge profession to move beyond weapons and defense
Engineering can create weapons systems or systems for defense and well-being. But can engineering create peace? In a Perspective, Guru Madhavan and colleagues propose an expansive mode of engineering practice that seeks to ...
Phys.org / Mapping cell development with mathematics-informed machine learning
The development of humans and other animals unfolds gradually over time, with cells taking on specific roles and functions via a process called cell fate determination. The fate of individual cells, or in other words, what ...
Phys.org / World not ready for rise in extreme heat, scientists say
Nearly 3.8 billion people could face extreme heat by 2050 and while tropical countries will bear the brunt cooler regions will also need to adapt, scientists said Monday.
Phys.org / Saltier seas in spring double the chance of extreme El Niño events, study finds
Stronger El Niño events are more likely when springtime surface waters in the western Pacific Ocean become unusually salty, a new study in Geophysical Research Letters suggests. Traditionally, scientists have focused on ...
Medical Xpress / Wood burning in homes drives dangerous air pollution in winter, study finds
Throwing another log into a crackling fireplace on a cold winter's night might seem like a cozy, harmless tradition. But Northwestern University scientists have found residential wood burning is a major—yet often overlooked—contributor ...
Phys.org / From stellar engines to Dyson bubbles, alien megastructures could hold themselves together under the right conditions
New theoretical models have strengthened the case that immense, energy-harvesting structures orbiting their host stars could exist in principle in distant stellar systems. With the right engineering precautions, calculations ...
Phys.org / Aging populations could cut global water use by up to 31%, study finds
Across the world, water scarcity is emerging as one of the most pressing challenges of the 21st century. Climate change is pushing rivers and aquifers into unprecedented extremes, droughts and floods are intensifying, and ...
