Log in to your computer with a secret message encoded in a molecule

Molecules like DNA are capable of storing large amounts of data without requiring an energy source, but accessing this molecular data is expensive and time consuming. Researchers have now developed an alternative method to encode information in synthetic molecules, which they used to encode and then decode an 11-character password to unlock a computer.

Stretched in a cross pattern: Our neighboring galaxy is pulled in two axes

Researchers have discovered that Cepheid variable stars in our neighboring galaxy, the Small Magellanic Cloud, are moving in opposing directions along two distinct axes. They found that stars closer to Earth move towards the northeast, while more distant stars move southwest. This newly discovered movement pattern exists alongside a northwest-southeast opposing movement that the scientists

Drinking water, select foods linked to PFAS in California adults

A new study examined associations between diet, drinking water, and ‘legacy’ PFAS — chemicals that were phased out of production in the US in the 2000s — with blood samples from California residents. PFAS exposure was associated with consumption of seafood, eggs, and brown rice, but fewer other foods than suggested by earlier studies. PFAS
