Scientists measure hidden quantum forces that could power a new generation of pharmaceutic

It's one thing to design a pharmaceutical drug. It's another to know if and why it actually works; not on paper or in a computer model, but inside the chaotic world of living systems, where proteins twist into shape, atoms constantly pull and push each other apart, and molecular

Metal hydride molecule trapped with laser light opens path to ultracold hydrogen

Controlling and trapping molecules, units of a substance consisting of two or more chemically bound atoms, with laser light is significantly more challenging than trapping individual atoms. This is because molecules exhibit more complex vibrational and rotational dynamics that ma

Secrets of how we see color revealed at the molecular level

A global team has cracked a decades-old mystery, revealing the atomic structures of the molecules in our eyes that allow us to see colors. "To understand how we detect light and perceive colors, we need to know the exact structure of light-sensitive molecules in our eyes," said T

Screen reveals new proteins that control RNA processing

Researchers at the University of California San Diego have developed a large-scale screening approach that identifies proteins controlling a fundamental step in gene expression known as alternative polyadenylation (APA). APA determines where an RNA molecule is cut and finished be

ROS-producing enzymes guide plant cell division and tissue patterning, gene-editing study

Reactive oxygen species (ROS) produced naturally during cellular metabolism often cause oxidative damage to cells. However, these molecules also play an important role in normal cellular signaling. While ROS are established as essential signaling molecules in various organisms, t

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

Lithium-doped carbon nanorings show promise for next-generation optical devices

Nonlinear optical materials are essential for advanced photonics and laser technologies, but researchers are still searching for ways to optimize organic, carbon-based alternatives. Using computational modeling, scientists demonstrated that adding a lithium atom to the outside of

Nanopore technology identifies proteins molecule by molecule

Proteins are responsible for most functions in the human body. However, their analysis, which is essential for understanding diseases, developing drugs and discovering new biomarkers, remains highly complex. Using a technology called "nanopore detection," a team at the University

Why nanoscale droplets don't coalesce and microscale droplets do

Olive oil and water do not naturally mix. Water molecules are polar, having a net electric dipole moment due to the bend angle of about 104.5° between the two oxygen-hydrogen bonds. Olive oil is nonpolar due to its long hydrocarbon chains, which makes it hydrophobic and insoluble

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

Structural blueprint for RNA therapeutics reveals why some siRNA molecules work better tha

RNA interference is a natural mechanism for living cells to control whether specific genes are being used. Crowned with the 2006 Nobel Prize in Physiology or Medicine, the discovery of RNA interference has since been harnessed by scientists to create a powerful and growing class

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
