Quantifying U.S. health impacts from gas stoves
A new study of air pollution in U.S. homes reveals how much gas and propane stoves increase people's exposure to nitrogen dioxide, a pollutant linked to childhood asthma. Even in bedrooms far from kitchens, concentrations frequently exceed health limits while stoves are on and for hours after burners and ovens...
Genomes of ‘star algae’ shed light on origin of plants
Land plants cover the surface of our planet and often tower over us. They form complex bodies with multiple organs that consist of a broad range of cell types. Developing this morphological complexity is underpinned by intricate networks of genes, whose coordinated action shapes plant bodies through various molecular mechanisms....
Birdwatching can help students improve mental health, reduce distress
A new study finds people who have nature-based experiences report better well-being and lower psychological distress than those who do not. Birdwatching in particular yielded promising results, with higher gains in subjective well-being and more reduction in distress than more generic nature exposure, such as walks. Because birdwatching is an...
Did a magnetic field collapse trigger the emergence of animals?
Researchers uncovered compelling evidence that Earth's magnetic field was in a highly unusual state when the macroscopic animals of the Ediacaran Period -- 635 to 541 million years ago -- diversified and thrived. Their study raises the question of whether these fluctuations in Earth's ancient magnetic field led to shifts...
Ice shelves fracture under weight of meltwater lakes
Heavy pooling meltwater can fracture ice, potentially leading to ice shelf collapse.
Plants utilize drought stress hormone to block snacking spider mites
Recent findings that plants employ a drought-survival mechanism to also defend against nutrient-sucking pests could inform future crop breeding programs aimed at achieving better broadscale pest control.
Source of pregnancy complications from infections revealed by placenta map
The placenta's response to infections from malaria, toxoplasmosis and listeria has been mapped in high resolution, possibly paving the way for new treatment options.
New Nevada experiments will improve monitoring of nuclear explosions
On an October morning in 2023, a chemical explosion detonated in a tunnel under the Nevada desert was the launch of the next set of experiments by the National Nuclear Security Administration, with the goal to improve detection of low-yield nuclear explosions around the world.
New eco-friendly lubricant additives protect turbine equipment, waterways
Scientists have developed lubricant additives that protect both water turbine equipment and the surrounding environment.
