Dynamics of molecular rotors in bulk superfluid helium
Molecules immersed in liquid helium can probe superfluidity since their electronic, vibrational and rotational dynamics can provide valuable cues about the superfluid at the nanoscale. In a new report in Science Advances, Alexander Milner and a team.....»»
Efficient antibody production "wobbles," new study finds
Molecular biology's central dogma posits a simple recipe for the construction of the human body: a DNA blueprint is transcribed into an RNA message, and the RNA message is translated into the proteins that make you. Translating the mRNA message is a.....»»
A new type of plant metalloreductase maintains root growth under low phosphorus
The release of low-molecular weight carboxylates, such as malate, is used by many plant species to mine poorly available phosphorus (P) from the soil. Malate can increase the availability of phosphate, the P form taken up by plants, by chelating triv.....»»
US–Indian satellite will monitor Earth"s changing frozen regions
NISAR, the soon-to-launch radar satellite from NASA and the Indian Space Research Organization (ISRO), will measure some key Earth vital signs, from the health of wetlands to ground deformation by volcanoes to the dynamics of land and sea ice......»»
A three-step mechanism explaining ultraviolet-induced CO desorption from CO ice
The desorption of CO ice induced by ultraviolet (UV) radiation is a phenomenon that occurs in some cold parts of the universe, which has often also been replicated in laboratory settings. While this phenomenon is now well-documented, the molecular me.....»»
Joking apart: What men and women find funny
Men rate visual jokes more highly than women do, whereas women prefer jokes that involve political commentary or the dynamics of close relationships, a new study of print cartoons dating from 1930-2010 finds......»»
Research team reports observing vibrational spectra of a single protein with infrared nanospectroscopy
An interdisciplinary research team, led by Assistant Prof. Jun Nishida and Associate Prof. Takashi Kumagai at the Institute for Molecular Science, has successfully observed vibrational spectra of single proteins, consisting of approximately 500 amino.....»»
Study reveals key molecular mechanisms involved in development of tomato plant
In an article published in the journal Development, researchers at the University of São Paulo's Luiz de Queiroz College of Agriculture (ESALQ-USP) in Brazil describe mechanisms relating to the development of the tomato plant (Solanum lycopersicum).....»»
Shape matters: Study finds microplastic fibers may travel as far as the stratosphere
How far microplastics travel in the atmosphere depends crucially on particle shape, according to a recent study by scientists at the University of Vienna and the Max Planck Institute for Dynamics and Self-Organization in Göttingen. Although spherica.....»»
Researchers discover molecular "barcode" used by bacteria to secrete toxins
Researchers at McMaster University have discovered a molecular "barcode" system used by disease-causing bacteria to distinguish between beneficial and toxic molecules......»»
Protein structures signal fresh targets for anticancer drugs
Cell replication in our bodies is triggered by a cascade of molecular signals transmitted between proteins. Compounds that block these signals when they run amok show potential as cancer drugs......»»
Progress in the investigation of ultrafast electron dynamics using short light pulses
When electrons move within a molecule or semiconductor, this occurs on unimaginably short time scales. A Swedish-German team, including Dr. Jan Vogelsang from the University of Oldenburg, has now made significant progress towards a better understandi.....»»
New theoretical framework unlocks mysteries of synchronization in turbulent dynamics
Weather forecasting is important for various sectors, including agriculture, military operations, and aviation, as well as for predicting natural disasters like tornados and cyclones. It relies on predicting the movement of air in the atmosphere, whi.....»»
Daily Telescope: A view of our star as Earth reaches perihelion
There is a bit of irony for those of us who live in the Northern Hemisphere. Enlarge / Sol, imaged by NASA's Solar Dynamics Observatory. (credit: NASA) Welcome to the Daily Telescope. There is a little too much darkne.....»»
Pathogenic bacteria use molecular "shuttle services" to fill their injection apparatus with the right product
Disease-causing bacteria of the genus Salmonella or Yersinia can use tiny injection apparatuses to inject harmful proteins into host cells, much to the discomfort of the infected person. However, it is not only with a view to controlling disease that.....»»
Deciphering molecular mysteries: New insights into metabolites that control aging and disease
In a significant advancement in the field of biochemistry, scientists at the Boyce Thompson Institute (BTI) and Cornell University have uncovered new insights into a family of metabolites, acylspermidines, that could change how we understand aging an.....»»
New crystalline sponge method proposed for undergraduate courses
The crystal sponge technology is a revolutionary technique, which enables the direct and precise determination of the molecular structure of liquid and gas targets. The technique uses a special network complex to selectively absorb liquid or gas targ.....»»
JWST sets a new record, sees newly forming stars in the Triangulum galaxy
Our Milky Way bristles with giant molecular clouds birthing stars. Based on what we see here, astronomers assume that the process of star creation also goes on similarly in other galaxies. It makes sense since their stars have to form somehow. Now, t.....»»
Artificial design and biosynthesis of a single-domain catenated dihydrofolate reductase
This study was led by Prof. Wen-Bin Zhang (College of Chemistry and Molecular Engineering, Peking University & Beijing Academy of Artificial Intelligence) and Dr. Jing Fang (College of Chemistry and Molecular Engineering, Peking University). A single.....»»
Novel molecular ionization dissociation pathway induced by Interatomic Coulombic Decay
A research group led by Prof. Ma Xinwen at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) has observed a novel molecular ionization dissociation pathway triggered by Interatomic Coulombic Decay (ICD). The study, publis.....»»
