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.....»»
Taming of a shape-shifter molecule
Shape-shifter molecules are in never-ending motion. Their structure fluctuates because the carbon bonds that hold them together constantly break up and form again. Researchers have now found a way to "tame" a shape-shifter molecule called bullvalene......»»
A single molecule makes a big splash in the understanding of the two types of water
It plays a fundamental role in human existence and is a major component of our universe, yet there are still things we don't understand about water. To address the knowledge gaps, a collaborative team of Institute of Industrial Science, The Universit.....»»
Bacterial genome is regulated by an ancient molecule
We are all collections of cells, each cell containing the instructions—our DNA—to become any other cell. What differentiates a heart cell from a skin cell from a brain cell is the expression—or silencing—of genes......»»
Researchers capture high-frequency oscillations in the gigantic eruption of a neutron star
An international scientific group with outstanding Valencian participation has managed to measure for the first time oscillations in the brightness of a magnetar during its most violent moments. In just a 10th of a second, the magnetar released energ.....»»
Scientists Finally Solve the Mystery of Why Comets Glow Green
A team of chemists just solved the mystery of why comets' heads -- but not their tails -- glow green, which had puzzled researchers for decades. From a report: Studying an elusive molecule, which only fleetingly exists on Earth, was the key. Comets a.....»»
Gallic acid and stretching decrease osteoarthritis markers in cartilage cells
Researchers used gallic acid, an antioxidant found in gallnuts, green tea and other plants, and applied a stretching mechanism to human cartilage cells taken from arthritic knees that mimics the stretching that occurs when walking. The combination no.....»»
Team develops the world"s first optical oscilloscope
A team from UCF has developed the world's first optical oscilloscope, an instrument that is able to measure the electric field of light. The device converts light oscillations into electrical signals, much like hospital monitors convert a patient's h.....»»
Detailed images of molecule associated with ALS could open door to therapies
Scientists have determined the structure of the molecule associated with amyotrophic lateral sclerosis (ALS) and multiple other neurodegenerative diseases. The researchers say this discovery could enable targeted development of new medical interventi.....»»
Research reveals how aging cells can be an underlying cause of kidney damage
A study in mice has found that stress and tissue damage initiated by angiotensin II, a molecule that is known to increase blood pressure and stiffening in the linings of blood vessels, leads to cellular senescence, a process by which a cell ages and.....»»
A deep learning model rapidly predicts the 3D shapes of drug-like molecules
In their quest to discover effective new medicines, scientists search for drug-like molecules that can attach to disease-causing proteins and change their functionality. It is crucial that they know the 3D shape of a molecule to understand how it wil.....»»
Molecular device turns infrared into visible light
Light is an electromagnetic wave: It consists of oscillating electric and magnetic fields propagating through space. Every wave is characterized by its frequency, which refers to the number of oscillations per second, measured in Hertz (Hz). Our eyes.....»»
Plant pathogen evades immune system by targeting the microbiome
A team of biologists has identified that the pathogenic fungus Verticillium dahliae, responsible for wilt disease in many crops, secretes an 'effector' molecule to target the microbiome of plants to promote infection. The research was performed by th.....»»
Modified protein from rattlesnake venom permits development of drug to modulate blood clotting
Researchers in Brazil and Belgium have developed a molecule of pharmaceutical interest from collinein-1, a protein found in rattlesnake venom. They used a technique called PEGylation to make the molecule, now called PEG-rCollinein-1, more stable in t.....»»

Researchers develop multicomponent nanopore machine that approaches single molecule protein sequencing
A team of researchers at the University of Groningen has developed a multicomponent nanopore machine that approaches single molecule protein sequencing—it uses a design that allows for unfolding, threading and degrading a desired protein. In their.....»»
For the first time, DNA and proteins sensed by de novo-designed nanopore
Researchers in Japan have designed the first bottom-up designed peptides, comprising chains of amino acids, that can form artificial nanopores to identify and enable single molecule-sorting of genetic material in a lipid membrane......»»
How a viral RNA changes shape to hijack host cells
University of Colorado Anschutz Medical Campus researchers have observed how an RNA molecule from a virus forms a complex, three-dimensional structure, and is able to change its shape to hijack host proteins. The details of this process, elusive to s.....»»
Research in mice shows how diet alters immune system function through a gut microbe
Research in mice demonstrates how diet alters a gut microbe molecule that, in turn, prompts immune cells to downregulate inflammation. The study elucidates molecular mechanism behind long-standing belief that diet, microbiota, and immunity influence.....»»
Scientists solve 50-year-old mystery behind plant growth
A team of researchers led by UC Riverside has demonstrated for the first time one way that a small molecule turns a single cell into something as large as a tree. For half a century, scientists have known that all plants depend on this molecule, auxi.....»»
New carbonyl rearrangement method could help identify new medicines, chemicals
Rearranging the parts of a molecule is like rearranging the contents of a tightly packed suitcase: You must go through a number of steps, taking objects in and out to get the configuration you want......»»
