Magnetic 'springs' break down marine microplastic pollution

Plastic waste that finds its way into oceans and rivers poses a global environmental threat with damaging health consequences for animals, humans, and ecosystems. Now, using tiny coil-shaped carbon-based magnets, researchers ...

Detox pathway extends lifespan of the worm C. elegans

A mutant worm with a change in one mitochondrial gene produces more reactive oxygen species (ROS), which can be harmful to cells by causing oxidative stress. However, this mutant worm is able to live twice as long as the ...

Modeling exoplanet atmospheres

All atoms and molecules emit distinctive spectral lines across the spectrum, the details of which depend on the internal structures of the species (for example, the vibration and rotation properties of molecules) and how ...

Electrons take alternative route to prevent plant stress

Plants are susceptible to stress, and with the global impact of climate change and humanity's growing demand for food, it's crucial to understand what causes plant stress and stress tolerance. When plants absorb excess light ...

Environmental oxygen triggers loss of webbed digits

Free fingers have many obvious advantages on land, such as in locomotion and grasping, while webbed fingers are typical of aquatic or gliding animals. But both amphibians and amniotes—which include mammals, reptiles, and ...

Environmental pollutants could impact cellular signs of aging

Researchers have linked some environmental pollutants with diseases, a decreased life span and signs of premature aging, such as wrinkles and age spots. But can accelerated aging be detected at the cellular level in healthy ...
