Rabi oscillations in a stretching molecule
Over eighty years ago, Rabi oscillations were proposed to describe the strong coupling and population transfer in a two-level quantum system exposed to an oscillatory driving field. As compared to atoms, molecules have an extra degree of vibration, w.....»»
Antifungal activity of a maleimide derivative: Disruption of cell membranes and interference with iron ion homoeostasis
A small molecule library consisting of 40 compounds, specifically N-substituted maleimide and its derivatives, were initially screened in a study published in the journal Mycology, which was led by Prof. Ying Li (Xuzhou Medical University), Prof. Zuo.....»»
Quantum interference could lead to smaller, faster, and more energy-efficient transistors
An international team of researchers from Queen Mary University of London, the University of Oxford, Lancaster University, and the University of Waterloo have developed a new single-molecule transistor that uses quantum interference to control the fl.....»»
Not just a lodger: Novel host-guest assembly provides enhanced reactivity
By design, synthetic molecules typically have specific jobs to prevent or accelerate reactions between other molecules. To help control more complicated reactions, researchers may harness spare space in one molecule to synthesize another chemical str.....»»
Quantum dance to the beat of a drum: Researchers observe how energy of single electron is tuned by surrounding atoms
Physicists at the University of Regensburg have choreographed the shift of a quantized electronic energy level with atomic oscillations faster than a trillionth of a second......»»
"Molecular Rosetta Stone" reveals how our microbiomes "talk" to us
Researchers from Skaggs School of Pharmacy and Pharmaceutical Sciences at the University of California San Diego have uncovered thousands of previously unknown bile acids, a type of molecule used by our gut microbiome to communicate with the rest of.....»»
Saturn"s moon is a testing ground to gain a better understanding of the methane molecule
Titan is the second-largest moon in the solar system and the only one with a dense atmosphere. At the top of this atmosphere, rich in nitrogen and methane, the sun's radiation produces a great diversity of organic molecules, some of which we also fin.....»»
Chemists break barriers and open up super-resolution molecule mass analysis
A team of chemists led by Prof. Albert Heck puts a new spin on analyzing and understanding molecules. By ingeniously improving current measuring equipment, the team was able to trap and observe individual molecules for a much longer period—up to 25.....»»
Research team designs small-scale "chemical nose"
A living organism's nose is essentially a biological molecule detector that sends neurological signals to the brain, which then decodes a particular scent. Human noses, with six million olfactory receptors, can distinguish more than one trillion scen.....»»
Using light to precisely control single-molecule devices
In a new Nature Communications study, Columbia Engineering researchers report that they have built highly conductive, tunable single-molecule devices in which the molecule is attached to leads by using direct metal-metal contacts. Their novel approac.....»»
Newly discovered protein prevents DNA triplication
Every time a cell divides, its DNA is duplicated so that the two daughter cells have the same genetic material as their parent. This means that, millions of times a day, a biochemical wonder takes place in the body: the copying of the DNA molecule. I.....»»
Trapping and excitation of the simplest molecule: Precise measurement matches theoretical predictions
The simplest possible molecule H2+ was one of the very first molecules to form in the cosmos. This makes it significant for astrophysics, but also an important object of research for fundamental physics. However, it is difficult to study in experimen.....»»
An alternate arrangement: How a propeller-shaped isomer can improve organic solar cells
Imagine technology as a race car speeding down a track—it can only go as fast as its engine allows. But just when it seemed like organic solar cells hit a roadblock, along comes 3PNIN, a game-changing molecule shaped like a propeller, ready to turb.....»»
New study shows similarities and differences in human and insect vision formation
Researchers at the University of California, Irvine have discovered profound similarities and surprising differences between humans and insects in the production of the critical light-absorbing molecule of the retina, 11-cis-retinal, also known as th.....»»
How to dim the consequences of global light pollution
Our ancestors could look up and see the Milky Way—our galaxy—as a large band of white light stretching across the sky. Because of light pollution, that's no longer the case. One study estimated that 60% of Europeans and 80% of Americans have neve.....»»
Accelerating the discovery of single-molecule magnets with deep learning
Synthesizing or studying certain materials in a laboratory setting often poses challenges due to safety concerns, impractical experimental conditions, or cost constraints. In response, scientists are increasingly turning to deep learning methods that.....»»
Researchers discover that a rare fat molecule helps drive cell death
Columbia researchers have found that a rare type of lipid is a key driver of ferroptosis, a form of cell death discovered by Columbia professor Brent Stockwell......»»
Chemists create an emission molecular thermometer
Future technologies rely on phenomena that were previously considered the exclusive domain of theoretical physics or chemistry. For example, the approach to devices with high-density information storage arose when chemists discovered single-molecule.....»»
First tetratomic supermolecules realized at nanokelvin temperatures
A team of experimentalists at the Max Planck Institute of Quantum Optics (MPQ) and theorists at the Chinese Academy of Sciences (CAS) has succeeded for the first time in populating and stabilizing a new type of molecule, so-called field-linked tetrat.....»»
Soapbark discovery offers a sustainability boost for the global vaccine market
A valuable molecule sourced from the soapbark tree and used as a key ingredient in vaccines, has been replicated in an alternative plant host for the first time, opening unprecedented opportunities for the vaccine industry......»»
