Steroids and high levels of carboxylic acids in teenagers’ body odor give off a mix of pleasant and acrid scents.
- Psychology
Timbre can affect what harmony is music to our ears
The acoustic qualities of instruments may have influenced variations in musical scales and preferred harmonies.
- Science & Society
Not all cultures value happiness over other aspects of well-being
Nordic countries topped the 2024 world happiness rankings. But culture dictates how people respond to surveys of happiness, a researcher argues.
- Archaeology
Human brains found at archaeological sites are surprisingly well-preserved
Analyzing a new archive of 4,400 human brains cited in the archaeological record reveals the organ’s unique chemistry might prevent decay.
- Health & Medicine
