Scientists have used light-activated molecular machines to induce cell-to-cell calcium signaling, revealing a powerful new strategy for drug design. This technology could lead to improved treatments ...

Scientists have built DNA-based nanocircuits that reset with heat, enabling reusable molecular systems for tasks like cargo sorting and pattern recognition. (Nanowerk News) Though it might seem like ...

Rotaxanes and related molecular machines represent a rapidly developing class of mechanically interlocked molecules that have captured the interest of chemists and materials scientists alike.

A study captured the first near frame-by-frame view of a self-splicing ribozyme assembling into its active form. Using cryo-EM, SAXS, biochemistry and molecular simulations, researchers mapped hidden ...

Sir Fraser Stoddart, who has died aged 82, was a phenomenally inventive Scottish-born scientist who shared the 2016 Nobel Prize in Chemistry with the Frenchman Jean-Pierre Sauvage and the Dutch ...

Researchers have used cryo-EM and computational tools to visualize ribozyme assembly, shedding light on life's most versatile ...

Ferrocene is a key molecule for developing molecular machines. However, it readily decomposes on the surface of flat noble metal substrates, marking a significant challenge. Now researchers have ...

Ana Santos, a microbiologist at Rice University, grew up in Cantanhede, a small city in Portugal that is known as a biotechnology hub and a source of good wine. When she was a child, her grandfather, ...

Scientists have discovered a remarkable way to destroy cancer cells. A study published last year found stimulating aminocyanine molecules with near-infrared light caused them to vibrate in sync, ...

Fast-scanning atomic force microscopy imaging of the molecule at two different time points shows positional shifts along the polymer chain on the left. On the right, the molecular structure of PEG ...

(Nanowerk News) One of the main ways cells “talk” to each other to coordinate essential biological activities such as muscle contraction, hormone release, neuronal firing, digestion and immune ...
