'Youngest' antibiotic kills bacteria via a new two-step mechanism

Scientists at Utrecht University have discovered a new mechanism antibiotics use to kill bacteria. The antibiotic teixobactin uses a dual molecular strategy: it blocks the bacterial cell wall synthesis and destructs the cell ...

Scientists reveal how detergents actually work

Scientists have discovered the precise way detergents break biological membranes, which could increase our understanding of how soaps work to kill viruses like COVID-19.

Knots in the resonator: Elegant math in humble physics

At the heart of every resonator—be it a cello, a gravitational wave detector, or the antenna in your cell phone—there is a beautiful bit of mathematics that has been heretofore unacknowledged.

How a shape-shifting receptor influences cell growth

Receptors found on cell surfaces bind to hormones, proteins, and other molecules, helping cells respond to their environment. MIT chemists have now discovered how one of these receptors changes its shape when it binds to ...

The rings of Uranus and Neptune could help map their interiors

Mapping the interior of the ice giants is difficult, to say the least. Not only are they far away and therefore harder to observe, but their constant ice cover makes it extremely hard to detect what lies underneath. So scientists ...
