Following this design principle, the researchers create angstrom-scale pores in bi-layer graphene sheets, and decorate the two pore edges with twisted rings of carbonyl groups. The artificial ion ...

For this article, author Jennifer Fisher Wilson interviewed Roderick MacKinnon, Howard Hughes Medical Institute investigator and head of the Laboratory of Molecular Neurobiology and Biophysics at ...

Scientists applied molecular dynamics simulations to visualize how potassium ions pass through a potassium ion channel at atomic resolution for the first time. (Nanowerk News) The patch clamp ...

Larger K+ (ionic radius: 1.3 Å) can selectively permeate larger Na + (ionic radius: 1.0 Å) through biological potassium ion channels, with selectivity ratios greater than 1000-fold. Scientists have ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Ion channels are attractive drug targets due to their importance in health and disease, but finding ways to target a specific ion channel selectively is a major challenge. Now, researchers at Weill ...

Underlying every thought, heartbeat and movement are ion channels, busily conducting high-speed streams of ions into cells, like subway trains coursing through tunnels. Ion channels span the cellular ...

Ion channels are attractive drug targets due to their importance in health and disease, but finding ways to target a specific ion channel selectively is a major challenge. Now, researchers have ...

The study, published in Materials Today, details how these membranes could significantly improve energy efficiency and operational stability. Precisely engineered in both pore size and surface ...
