The Science Behind Petrichor: Why Rain Smells Earthy

The earthy scent after rain, known as petrichor, is caused by geosmin, a chemical produced by ancient soil bacteria called Streptomyces. Humans are highly sensitive to geosmin, which may have offered an evolutionary advantage in detecting water or healthy soil. These bacteria also produce many life-saving antibiotics.

Third Dark Matter-Deficient Galaxy DF9 Discovered Along NGC 1052 Trail

A third galaxy, DF9, has been found to be missing dark matter, joining DF2 and DF4 along the NGC 1052 trail. Observations suggest DF9's mass is almost entirely from its stars, challenging the assumption that galaxies are dominated by dark matter. This discovery strengthens the theory that a single disruptive event created these unusual galaxies.
