Phys.org / What happens when you flush? Study reveals how toilet aerosols reach the breathing zone
Researchers from Flinders University have found that flushing toilets can release aerosols and bioaerosols into the surrounding air, with some studies detecting particles at heights corresponding to adults' breathing zones.
Medical Xpress / How the heart, lungs and brain work together to shape experience
People speak of "butterflies in the stomach," a "racing heart," being "choked up" or needing to "catch breath." Language routinely treats emotion and thought as though they inhabit the body. But why are events of the mind ...
Phys.org / How climate change may amplify the impact of earthquakes in the Arctic
Permafrost refers to permanently frozen ground. The rock is held together by ice, much like cement binds concrete. However, when the ice thaws, the ground becomes weak and unstable. During an earthquake, this can trigger ...
Phys.org / Why 'you're smart' can backfire: Young children may cheat more after ability praise
Parents and teachers might think telling kids "they're smart" is a helpful way to build self-confidence and support positive development.
Phys.org / Slender crystal's blue-to-yellow glow could make invisible forces visible
Applying pressure to luminescent organic crystals usually brings molecules closer together and weakens their fluorescence. Materials that instead brighten and undergo a large color change are rare, and clear design principles ...
Tech Xplore / Climate, not concrete mix, may drive steel corrosion in low-carbon structures
It is hard to imagine the modern world without concrete. Enormous quantities are used in construction worldwide, and the production of cement—its main ingredient—generates a great deal of CO₂, a greenhouse gas that accelerates ...
Medical Xpress / Patient questionnaires may add a new layer to chronic lymphocytic leukemia prognosis
Patients' responses to questions routinely raised by oncologists may provide important clues about their chances of survival from chronic lymphocytic leukemia (CLL), according to a new study published in the journal Therapeutic ...
Phys.org / Can atmospheric methane removal limit peak warming?
In a new report, the United Nations Environment Program (UNEP) concludes that global warming is expected to exceed 1.5°C within the next few years. This makes two questions increasingly important: how high will temperatures ...
Medical Xpress / Atherosclerosis may meet key criteria for autoimmune disease, evidence suggests
In autoimmune diseases, the immune system turns against the body through pathogenic high-affinity B cells or T cells, leading to severe organ damage. Multiple sclerosis (nervous system paralysis), type 1 diabetes (a strong ...
Phys.org / How 'hyperselection' is making modern life efficient, pleasant—and boring
It's difficult to imagine a song like Queen's 1975 "Bohemian Rhapsody" topping the charts today. Almost six minutes long, it moves through several radically different musical sections and famously ignores the conventional ...
Phys.org / Reversible electric control unlocks persistent chiral phonon states
Atoms in a material are rarely still. They jiggle back and forth in collective lattice vibrations known as phonons. Their motion can also carry a rotational element: In 2023, scientists at PSI experimentally proved the existence ...
Phys.org / Neutrophil vesicles help Candida albicans evade immune-cell engulfment
The immune system is a highly sophisticated defense network designed to protect against pathogens. A research team from the Universities of Würzburg and Jena and the Leibniz Institute for Natural Product Research and Infection ...
