A hydrogen bond forms between a propellane (lower molecule) and the carbon monoxide functionalized tip of an atomic force microscope. The measured forces and the distance between the oxygen atom at the AFM tip and the propellane’s hydrogen atoms correspond precisely to the calculations.

This is an infographic of NIST technique for quantum control of molecules. Credit: Hanacek/NIST National Institute of Standards and Technology (NIST) physicists have solved the seemingly intractable puzzle of how to control the quantum properties of individual charged molecules, or molecular ions. The solution is to use the same kind of “quantum logic” that drives

6DNM-amine is a proof of concept that the new approach can transform gram-positive antibiotics to drugs that can also kill gram-negative microbes. Credit: Photo by L. Brian Stauffer Scientists report that they now know how to build a molecular Trojan horse that can penetrate gram-negative bacteria, solving a problem that for decades has stalled the

This graphic reflects three scales: the macroscopic snowflake (blue lines), the molecular structure (red tube model), and the electron scattering diffraction (density plot). Credit: Tufts University. More than 400 years ago, renowned mathematician and scientist Johannes Kepler speculated about the creation of one of nature’s most angelic and unique shapes: the six-sided snowflake. Although atoms

Professor Fernando Uribe-Romo and his team of students created a way to trigger a chemical reaction in a synthetic material called metal-organic frameworks (MOF) that breaks down carbon dioxide into harmless organic materials. Think of it as an artificial photosynthesis process similar to the way plants convert carbon dioxide and sunlight into food. But instead

The scientists conducted their experiments in Staphylococcus aureus, a common cause of skin, sinus and lung infections.

Traditionally speaking, crystals — like salt, sugar or even diamonds — are simply periodic arrangements of atoms in a three-dimensional lattice.

Traditionally speaking,

Tiny incubators were used to simulate early Earth conditions, tracking microbial diversity and methane emissions over a period of 500 days.

Risky alcohol consumption can increase at time of retirement Credit: © / Fotolia Of retiring employees, 12 percent increased their risky drinking at the time of retirement. However, for most people, there was no change in risky level alcohol consumption around the time of retirement: 81 percent sustained healthy drinking during the follow-up, and
