Physicists discover molecule-like structure of nuclear ground state
Scientists from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS), along with their collaborators, have recently discovered a molecular-type structure in the ground state of atomic nuclei. The study was published in Physi.....»»
A novel quantification method for ribonucleotides, which are needed in almost all cellular processes
RNA (ribonucleic acid), which is made up of ribonucleotides, is a molecule found in all living organisms. RNA is thought to have probably preceded DNA in primordial life billions of years ago. RNA was eventually replaced by DNA as a chemically more s.....»»
A fullerene-like molecule made entirely of metal atoms
A small team of chemists from Nankai University, Nanjing Tech University and Shanxi University, all in China, working with a colleague from Universidad San Sebastián, in Chile, has, for the first time, created a fullerene-like molecule made entirely.....»»
Combining extreme-ultraviolet light sources to resolve a quantum mechanical dissociation mechanism in oxygen molecules
For the first time, researchers have succeeded in selectively exciting a molecule using a combination of two extreme-ultraviolet light sources and causing the molecule to dissociate while tracking it over time. This is another step towards specific q.....»»
Researchers tune the speed of chirality switching
Chiral molecules can have dramatically different functional properties while sharing identical chemical formulae and almost identical structures. The molecular structure of two types of a chiral molecule—so-called enantiomers—are mirror images of.....»»
Researchers develop self-sorting coacervates for high-order protocell networks
Protocell networks assembled by artificial cell-like compartments have been developed for the expansion of cell-mimicking functionalities, such as signal processing, protein expression, morphological differentiation, and energy harvesting......»»
New antifungal molecule kills fungi without toxicity in human cells, mice
A new antifungal molecule, devised by tweaking the structure of prominent antifungal drug Amphotericin B, has the potential to harness the drug's power against fungal infections while doing away with its toxicity, researchers at the University of Ill.....»»
An optical and electrically driven single-molecule Raman switch
The role of molecular junctions in nanoelectronics is most often associated with electronic transport; however, their precise characterization hinders their widespread development. Recently, most research has focused on investigating molecular juncti.....»»
Poison expert allegedly poisoned wife—with a shockingly toxic gout drug
Colchicine is centuries old, but the line between toxic and nontoxic is still blurry. Enlarge / Ball-and-stick model of the colchicine molecule. (credit: Wikimedia | Ben Mills) A Minnesota doctor who had worked for a poi.....»»
Scientists shed light on potential breakthrough biomedical molecule
Scientists from the Department of Energy's SLAC National Accelerator Laboratory have gained valuable insights into producing nitroxide, a molecule with potential applications in the biomedical field. While nitric oxide (NO) has long been on researche.....»»
Declining Bering Sea ice linked to increasing wildfire hazard in northeast China
China has been making strides in recent years to reduce air pollution, including fitting filters in coal-fired power stations to remove sulfur dioxide from emissions, a molecule that reacts with other compounds in the atmosphere to form polluting par.....»»
Scientists discover new molecule that combats viral infection in bacteria
A Ph.D. researcher at the University of St Andrews studying microbes in the human gut has discovered a new molecule that acts as a "distress signal" when viruses are detected. The research is published in the journal Nature......»»
Harnessing molecular power: Electricity generation on the nanoscale
Wave energy technology is a proven source of power generation, but there is power inherent in every molecule of liquid on Earth, even when the liquid is at rest. At the molecular scale, atoms and ions are always moving. If this nanoscale movement can.....»»
Direct imaging of sequences and locations of glycans bound to biomolecules at a single-molecule level
A team of organic chemists at the Max-Planck Institute for Solid-State Research, working with colleagues from the University of Tübingen and the University of Copenhagen, reports a way to take pictures of the sequences and locations of glycans (also.....»»
Mimicking a bird"s sticky spit to create cellulose gels
