Canopy soils that form on tree branches contain three times more carbon than soils on the ground in Costa Rica, potentially serving as an important carbon sink around the world.
Theropod dinosaur jaws became stronger as they evolved
Theropod dinosaurs evolved more robust jaws through time allowing them to consume tougher food, a new study reveals.
Greenland’s nutrients changing, with global impact
Scientists have discovered the availability of carbon in Greenland's waters is shifting poleward and appearing earlier than in previous decades. This finding will enhance understanding of carbon cycling and nutrient availability in this rapidly warming and changing environment.
Skin sensing made easier: Improved methods facilitate monitoring of body movement and health
Scientists simplify fabrication methods and model human skin structure in designing wearable sensors. This methodology reduces costs, enhances scalability and modular fabrication, and provides effective, wide-ranging sensitivity in wearable pressure sensors.
Concurrent heatwaves seven times more frequent than in 1980s
Multiple large heatwaves the size of Mongolia occurred at the same time nearly every day during the warm seasons of the 2010s across the Northern Hemisphere, according to a new study. Using ERA5 climate data from 1979 to 2019, the researchers found that the number of heatwaves occurring simultaneously in...
Time lag between intervention and actual CO2 decrease could still lead to climate tipping point
A simplified mathematical model of carbon dioxide (CO2) concentrations and temperature found a 'lag time' between human intervention and an actual decrease in CO2 levels. This lag time has ramifications for intervention strategies meant to avoid climate tipping points and potentially catastrophic temperature increases.
How a fly’s brain calculates its position in space
Neurons in the fly brain appear to literally perform vector math in order to signal the direction in which their bodies are traveling, regardless of which way their heads are pointing.
Study of Antarctic ice’s deep past shows it could be more vulnerable to warming
Insights into how the West Antarctic Ice Sheet responded to a warmer climate millions of years ago could improve predictions of its future.
Biodiversity loss in plants worldwide
Naturalized alien plants are causing a worldwide decline in the uniqueness of regional floras, according to the results of a global research project.
Meltwater influences ecosystems in the Arctic Ocean
In the summer months, sea ice from the Arctic drifts through Fram Strait into the Atlantic. Thanks to meltwater, a stable layer forms around the drifting ice atop the salty seawater, producing significant effects on biological processes and marine organisms.
