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 / 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 ...
Phys.org / Climate shapes arms race between ants and their social parasites
Two new studies show how climate influences behavior, communication, and genome evolution—driving adaptation in a long-running conflict.
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 / 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 ...
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 ...
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 / 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 / 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 / Rare image of Tatooine-like planet is closest to its twin stars yet
In a discovery that's fit for a movie, Northwestern University astronomers have directly imaged a Tatooine-like exoplanet, orbiting two suns. While obtaining an image of a planet beyond our solar system is already rare, finding ...
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 / One of NASA's key cameras orbiting Mars takes 100,000th image
After nearly 20 years on the Red Planet, NASA's Mars Reconnaissance Orbiter (MRO) has snapped its 100,000th image of the surface with its HiRISE camera. Short for High Resolution Imaging Science Experiment, HiRISE is the ...
