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.....»»
Liquid metal encased in hydrogel makes a promising energy-harvesting device
Any mechanical motion deforms the device, such as squishing, stretching, twisting. Enlarge / Researchers at North Carolina State University have created a soft and stretchable device that converts movement into electricity. The device works in w.....»»

Sequencing multiple RNA base modifications simultaneously: A new era of RNA biology
After a gene is transcribed into RNA, modifications can occur to the subunits or "bases" that make up the RNA molecule, which can affect its structure and function. The study of these changes is known as "epitranscriptomics." These base modifications.....»»
Organic molecule remnants found in nuclei of ancient dinosaur cells
A team of scientists from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences and from the Shandong Tianyu Museum of Nature (STM) has isolated exquisitely preserved cartilage cells in a 125-million.....»»
Scientists ID sterol essential for oil accumulation in plants
Scientists seeking to unravel the details of how plants produce and accumulate oil have identified a new essential component of the assembly line. They discovered a particular sterol—a molecule related to cholesterol—that plays a key role in the.....»»
Regulator proteins or symphonies of genes: Statistical modeling points way toward unified theory for DNA folding
At more than 2 meters long, the human DNA molecule uses intricate folding patterns to fit into cells while locally unfolding to express genes. Such phenomena, however, are difficult to measure in experiments, and theoretical frameworks explaining the.....»»
Molecule-mediated surface reconstruction enables giant upconversion luminescence enhancement
National University of Singapore researchers have developed a synthetic method to enhance upconversion luminescence in protein-sized lanthanide-doped nanocrystals by surface reconstruction through molecule coordination. This innovation prevents surfa.....»»
Is wildfire soot leaving a mark on the world"s oceans?
When clouds of smoke and ash billow out over the ocean, stretching away from the wildfires that are their source, they might not just affect the air quality. Rather, the wildfire soot could leave a chemical mark on the waters below......»»
The microbial molecule that turns plants into zombies
A newly discovered manipulation mechanism used by parasitic bacteria to slow down plant aging, may offer new ways to protect disease-threatened food crops......»»
Hard single-molecule magnets: Tetranuclear rare earth metal complexes with giant spin
Magnets formed from a single molecule are of particular interest in data storage, since the ability to store a bit on every molecule could vastly increase the storage capacity of computers. Researchers have now developed a new molecular system with a.....»»
Under the scanner: Scientists unravel the inner workings of DNA repair enzymes
DNA is the instruction manual for every living organism, guiding the development and functioning of all biological processes. In essence, it is a molecule with a double helix structure with each unit of a helix containing what are known as "DNA bases.....»»
Developing better nanopore technology
At the simplest of levels, nanopores are (nanometre-sized) holes in an insulating membrane. The hole allows ions to pass through the membrane when a voltage is applied, resulting in a measurable current. When a molecule passes through a nanopore it c.....»»
Saturn"s Insides Are Sloshing Around
A new paper suggests Saturn's core is more like a fluid than a solid, and makes up more of the planet's interior than we thought. From a report: With its massive rings stretching out 175,000 miles in diameter, Saturn is a one-of-a-kind planet in the.....»»
Examining the intricacies of ozone removal by deciduous forests
Ozone plays a vital role in Earth's climate system. In the stratosphere, which begins about six miles (9.7 kilometers) off the ground, ozone protects the planet from harmful ultraviolet radiation. Lower in the atmosphere, however, the molecule is an.....»»
Identifying an elusive molecule key to combustion chemistry
Researchers at the University of Pennsylvania and Argonne National Laboratory have made the most direct observation of a key intermediate formed during the breakdown of hydrocarbons in combustion and the atmosphere. Published in Science, this evidenc.....»»
Mountain lions moved less, downsized territory during LA"s pandemic shutdown
As people sheltered in place at the onset of the COVID-19 pandemic, sightings of wildlife in urban areas helped spawn a meme, "Nature is healing," that reflected an intuitive belief: Carnivores were stretching their legs, and their ranges, by expandi.....»»
Calling through the "DNA wire"
Proteins can communicate through DNA, conducting a long-distance dialog that serves as a kind of genetic "switch," according to Weizmann Institute of Science researchers. They found that the binding of proteins to one site of a DNA molecule can physi.....»»
Illuminating tissue formation through flourescence
Researchers at ETH Zurich have developed a molecule that fluoresces where new tissue is forming in the body. Alongside helping to detect tumors, the molecule could play a significant role in research of wound healing disorders......»»
How chemical reactions compute
A single molecule contains a wealth of information. It includes not only the number of each kind of constituent atom, but also how they're arranged and how they attach to each other. And during chemical reactions, that information determines the outc.....»»
Sierra Nevada red fox to be listed as federally endangered
The slender, bushy-tailed Sierra Nevada red fox will be listed as an endangered species, federal wildlife officials announced Monday, saying its population has dipped to just 40 animals in area of California stretching from Lake Tahoe to south of Yos.....»»
