Clean crystal surface lets single molecules hit ultimate quantum limit

Scientists at the Max Planck Institute for the Science of Light (MPL) have developed a technique for interrogating molecules on surfaces with spectroscopic precision, thereby reaching the ultimate quantum limit for the first time. With their findings, published in Science, the re

Switching spin states in manganese ions with light opens new path for molecular memory

Researchers at Johannes Gutenberg University Mainz (JGU) have developed a new way to use molecules as tiny data storage devices with a new manganese-based material. Until now, this was possible only with iron-containing molecular materials, which require very low temperatures—ran

Lipids and DNA nanostructures independently control artificial cell mechanics

What if the mechanical properties of a cell could be programmed like the components of a machine? Researchers at the University of Tokyo have discovered that two fundamental modes of cellular deformation—stretching and bending—can be independently controlled using different molec

Jellyfish reveal rapid repair system behind scar-free healing

A decade ago this summer, at the Marine Biological Laboratory, Jocelyn Malamy watched jellyfish cells "walk" toward each other to close a wound for the first time. An associate professor of molecular genetics and cell biology at the University of Chicago, Malamy had received tran

Loss of DNA protector gene exposes vulnerabilities in cancerous cells

Every time a cell copies its DNA, parts of the genome are exposed and vulnerable to damage or errors. Molecular biologist Simon Boulton is interested in how cells spot and repair damage to their DNA, and what happens if this process fails or if key genes are mutated.

Crystal-design principle reveals how competing molecular forces control structure, color a

Organic molecular crystals can respond to external stimuli such as heat, light, and mechanical force, making them attractive candidates for next-generation functional materials. However, predicting how multiple intermolecular interactions cooperate or compete to govern crystal be

Synchronized infrared lasers control molecular shape changes and expose hidden fingerprint

Researchers from the Molecular Physics and Physical Chemistry departments of the Fritz Haber Institute have shown how two highly synchronized infrared (IR) laser beams can control molecules as they switch between different structural conformations. Their study provides a new wind

Purine-heavy DNA sequences protect Bacillus subtilis genes from Rho termination

In the study of bacteria, a longstanding dogma has held that two molecular machines—RNA polymerase, which leads the way in transcribing DNA into RNA, and ribosomes, which bring up the rear translating RNA into proteins—worked so closely in tandem that they were effectively attach

Scientists observe water's behavior in a single molecular layer

New research has revealed that water behaves differently when confined to spaces just one molecule thick. For the first time, scientists have directly measured the vibrational signatures of truly two-dimensional water. In a study published in Nature Communications, researchers us

Watching how molecules change shape in slow motion could inform future molecular machines

Researchers at the Nano Life Science Institute (WPI-NanoLSI) at Kanazawa University, the Institute for Molecular Science and SOKENDAI have uncovered the hidden mechanism behind a molecular switch—a molecule that can change between different structural states in response to a chem

Quantum computers model nine fusion fuel material configurations for first time

A team of scientists from Oak Ridge National Laboratory, Cleveland Clinic and IBM has calculated nine molecular configurations of a promising material to produce fuel for fusion energy—the first known instance of such computations on quantum computers.

Quantum vacuum could help break molecular bonds with less energy, simulations suggest

A team of researchers led by Felipe Herrera, a professor at the University of Santiago and a researcher at the Millennium Institute for Research in Optics (MIRO), has identified a quantum phenomenon that enables chemical bonds to be broken using significantly less energy than is
