Phys.org / Iron minerals' hidden chemistry explains how soils trap carbon
While scientists have long known that iron oxide minerals help lock away enormous amounts of carbon—sequestering it from the atmosphere—a new Northwestern University study now reveals exactly why these minerals are such ...
Phys.org / Tiny particles 'surf' microcosmic waves to save energy in chaotic environments
Conditions can get rough in the micro- and nanoworld. For example, to ensure that nutrients can still be optimally transported within cells, the minuscule transporters involved need to respond to the fluctuating environment. ...
Phys.org / Portable optical scanner reveals hidden ozone damage in plant leaves
Escalating pollution and contamination of water and soil are emerging as serious threats to plant growth and its overall health. Plants are exposed to environmental pollutants for extended periods and exhibit changes in their ...
Medical Xpress / AI helps explain how covert attention works and uncovers new neuron types
Shifting focus on a visual scene without moving our eyes—think driving, or reading a room for the reaction to your joke—is a behavior known as covert attention. We do it all the time, but little is known about its neurophysiological ...
Phys.org / Climate change can affect human diseases in widespread and varied ways
As the planet edges towards 1.5°C of global warming, a new study led by the Natural History Museum, London has revealed that scientists still have only a limited understanding of how climate change is reshaping the risk ...
Phys.org / A new species of tiny orange frog discovered in Brazil's cloud forests
Despite the vast numbers of animal species already identified, the natural world is still capable of springing a few surprises. Deep in the cloud forests of the Serra do Quiriri mountain range in the southern Brazilian Atlantic ...
Phys.org / Parker Solar Probe spies solar wind 'U-turn'
Images captured by NASA's Parker Solar Probe as the spacecraft made its record-breaking closest approach to the sun in December 2024 have now revealed new details about how solar magnetic fields responsible for space weather ...
Phys.org / Arctic sees unprecedented heat as climate impacts cascade
The Arctic has experienced its hottest year since records began, a US science agency announced Tuesday, as climate change triggers cascading impacts from melting glaciers and sea ice to greening landscapes and disruptions ...
Medical Xpress / Cancer messenger substances disrupt muscle function and trigger muscle breakdown
Cancer patients often lose excessive amounts of weight. This affects up to 80% of patients and is mainly due to a decrease in muscle mass and fatty tissue. This cancer-induced cachexia (CIC) is triggered by cancer cytokines, ...
Phys.org / Amazon could lose over a third of forest cover by century's end
A new LMU study estimates that land use changes in conjunction with climate change could lead to the loss of up to 38% of the Amazon rainforest by the end of the 21st century.
Phys.org / Inclusive cues on job sites often fail to influence job seekers' applications
While diversity, equity and inclusion (DEI) regulations are widely accepted in the hospitality and tourism sector, new research shows applicants may still encounter barriers to securing roles because of automated processes ...
Phys.org / Interstellar comet keeps its distance as it makes its closest approach to Earth
A stray comet from another star swings past Earth this week in one last hurrah before racing back toward interstellar space.
