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.....»»
Bioengineered yeast mass produces herbal medicine
Herbal medicine is difficult to produce on an industrial scale. A team of Kobe University bioengineers manipulated the cellular machinery in a species of yeast so that one such molecule can now be produced in a fermenter at unprecedented concentratio.....»»
Testing thousands of RNA enzymes helps find first "twister ribozyme" in mammals
The "RNA world" hypothesis proposes that the earliest life on Earth may have been based on RNA—a single-stranded molecule similar in many ways to DNA—like some modern viruses. This is because, like DNA, RNA can carry genetic information, but, lik.....»»
Deep sea rocks suggest oxygen can be made without photosynthesis, deepening the mystery of life
Oxygen, the molecule that supports intelligent life as we know it, is largely made by plants. Whether underwater or on land, they do this by photosynthesizing carbon dioxide. However, a recent study demonstrates that oxygen may be produced without th.....»»

Single-molecule tracking technology streamlines drug discovery
New drug discovery is a critical step for improving patients' lives. First, researchers must identify molecules in the body's cells that help drive disease, as these are potential targets for new drugs. The next step is to screen candidate drugs that.....»»
Official Nintendo Music app debuts today to deliver 40-years of iconic tunes to your iPhone
Update: The new Nintendo Music app is now live on Apple’s App Store and Google Play. After stretching its P-wings a little bit into the (sort of) smart alarm clock world with the new Alarmo earlier this month, today the Mushroom Kingdom is mov.....»»
Newly developed methodology breaks molecular symmetry to back one theory about life"s origin
The vast majority of organic molecules (based on a carbon structure) are not flat, but have a three-dimensional geometry. Various results can be obtained depending on the way the atoms are arranged inside each molecule. In some cases, a molecule and.....»»
New research visualizes how fishing communities can change fishing habits to adapt to climate change
In a massive research project spanning five years and stretching the length of the Northeast seaboard, a Wellesley College professor is examining how various fishing communities can change their fishing habits in order to adapt to climate change......»»
Single-molecule imaging reveals aberrant DNA-binding dynamics of cancer-linked chromatin remodelers
Biophysical chemists from the National University of Singapore (NUS) have uncovered a previously hidden landscape that governs the intracellular organization and dynamics of SWI/SNF chromatin remodelers, an important class of protein complexes that c.....»»
New method for measuring luminescence lifetime offers versatility in scientific imaging
Oxygen is a key molecule for life, and in order to understand ecosystem dynamics it can be important to follow its ways in much detail. Optical sensors that use luminescent dyes have long been used to map oxygen levels in marine systems. Oxygen reduc.....»»
Plant stem cells: Understanding the biological mechanism of growth control
Researchers from the University of Freiburg have identified the HAN molecule as an important regulator that controls plant growth in conjunction with WOX5. Understanding this mechanism is relevant for breeding more resilient or higher-yielding crops......»»
Advanced model predicts gene architecture via nucleosome position
DNA—the molecule that carries the genetic information of all living organisms—is packaged within cells in a complex manner that allows it to function efficiently. Nucleosomes facilitate DNA compaction and also play a crucial role in regulating ge.....»»
Researchers discover how plants produce a novel anti-stress molecule
New research identifies for the first time the genes that help plants grow under stressful conditions—with implications for producing more sustainable food crops in the face of global climate change......»»
Key molecule in wound healing identified through mapping of long non-coding RNA molecules
A new study from Karolinska Institutet and the Chinese Academy of Medical Sciences has identified an RNA molecule that is important for skin wound healing. The research, published in Nature Communications, may have implications for the treatment of h.....»»
Nanopore technique shows transport mechanism of chaperone proteins at the single-molecule level
Proteins control most of the body's functions, and their malfunction can have severe consequences, such as neurodegenerative diseases or cancer. Therefore, cells have mechanisms in place to control protein quality......»»
Developing novel chiral capsule tools for advanced optical technologies
Chirality is an essential property in biology; the molecular building blocks of some of the most important biological structures, including DNA and proteins, are chiral. When a molecule is said to be chiral, it means that it is distinguishable from i.....»»
Fluorescent molecules to illuminate life: Simplified synthesis with formaldehyde
A research team has recently made a breakthrough in synthesizing organic fluorophores more cost-effectively and atom-efficiently than ever before by using formaldehyde, the simplest carbon molecule. Their findings were published in Angewandte Chemie.....»»
Exploring the role of hydrogen sulfide in the expression of iron uptake genes in E. coli
Antibiotic resistance and oxidative stress response are important biological mechanisms that help bacteria thrive, especially pathogenic bacteria like Escherichia coli. Hydrogen sulfide (H2S), a chemical messenger molecule, regulates several intracel.....»»
A single peptide helps starfish get rid of a limb when attacked
A signaling molecule that's so potent injected animals may drop more than one limb. Enlarge (credit: Hal Beral) For many creatures, having a limb caught in a predator’s mouth is usually a death sentence. Not starfish,.....»»
Floquet engineering tunes ultracold molecule interactions and produces two-axis twisting dynamics
