Does fertility affect a woman’s body odour?

New study also uses chemical analysis

26-Jul-2024 - Who we choose as a partner depends in part on who we find attractive on the outside. Scientists have long wondered whether potential partners can also sense a woman’s fertility, for example through subtle changes in her body odour. Researchers from Leipzig University, the Max Planck Institute for ...

Making it easier to differentiate mirror-image molecules

Researchers have shown that mirror-image substances – so-called enantiomers – can be better distinguished using helical X-ray light

06-Jul-2022 - Using a new method, scientists are better able to distinguish between mirror-image substances. This is important amongst others in drug development, because the two variants can cause completely different effects in the human body. Researchers from Paul Scherrer Institute PSI, EPF Lausanne ...
