Better kombucha brewing through chemistry

Kombucha brewers can now optimize their brews with science. The team discovered that silicone bags expose SCOBYs to more oxygen, speeding up brewing time and reducing ethanol levels. Additionally, using glucose as the SCOBY food source creates a kombucha with more gluconic acid and minimal ethanol.

Smelling danger in the water: Schreckstoff mystery solved after 86 years!

Researchers have solved the long-standing question of what triggers the alarm response in fish by identifying two distinct chemical signals: Daniol sulphate and Ostariopterin. These substances convey separate pieces of information that must be detected simultaneously to trigger a flight-or-freeze response.
