How inflammatory signalling molecules contribute to carcinogenesis
Researchers have managed to identify a previously unknown molecular connection between an inflammatory signalling molecule and one of the main oncogenes......»»
Enhancing the immunosuppressive properties of human umbilical cord mesenchymal stem cells
Mesenchymal stem cells (MSCs) have great potential for the treatment of various immune diseases due to their unique immunomodulatory properties. However, MSCs exposed to the harsh inflammatory environment of damaged tissue after intravenous transplan.....»»
Are rents rising in your neighborhood? Don"t blame the baristas
Baristas who work in specialty coffee shops, along with hipsters more generally, have been referred to as the "shock troops" of urban gentrification—and it's no different in Philadelphia. These servers of artisanal coffee contribute to economic and.....»»
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.....»»
Bacteria found to contribute to the modulation of animal behavior
An increasingly important field of work in modern life sciences is the study of the symbiotic coexistence of animals, plants, and humans with their specific microbial populations. In recent years, researchers have gathered growing evidence that the c.....»»
Does rainfall in southern China contribute to air pollution in the North China Plain?
The North China Plain (NCP) is a region with some of the worst air pollution conditions on a global scale. Air pollution (known as haze) dominated by higher PM2.5 concentration, is well-documented for its adverse impacts on both human health and soci.....»»
An effective approach for preparing supramolecular polymers at high concentration
Supramolecular polymers (SPs) are molecular assemblies composed of non-covalently bonded small molecules. They show high recyclability originating from their dynamic nature of monomer binding, which is different from covalent polymers with non-biodeg.....»»
Plants are likely to absorb more carbon dioxide in a changing climate than we thought—here"s why
The world's vegetation has a remarkable ability to absorb carbon dioxide (CO2) from the air and store it as biomass. In doing so, plants slow down climate change since the CO2 they take up does not contribute to global warming......»»
Study looks at RNA"s solo act on the ever-changing stage of cellular dynamics
RNA has been in the limelight for its starring role in cutting-edge vaccine technology, but RNA molecules are also key players in the inner workings of cells......»»
Researchers boost vaccines and immunotherapies with machine learning to drive more effective treatments
Small molecules called immunomodulators can help create more effective vaccines and stronger immunotherapies to treat cancer......»»
Use of urine in fertilizer can contribute to increased food security
The production of mineral based fertilizers requires a significant amount of energy and relies in part on non-renewable resources such as phosphate rock. Furthermore, the price of mineral fertilizer is currently at a record high due to surging input.....»»
Vinigrol targets protein disulfide isomerase to block inflammatory response, shows study
Researchers led by Prof. Wang Lei from the Institute of Biophysics of the Chinese Academy of Science (CAS) and their collaborators have identified the direct target of vinigrol as protein disulfide isomerase (PDI) on the cell membrane. Vinigrol activ.....»»
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.....»»
People who contribute least in crowdsourcing can do the most to improve a public good, says study
Whether talking about the office kitchen, hiking trails or ratings on Yelp, there are always people who put in effort to leave those spaces better. There are also those who contribute nothing to that public good......»»
How machine learning can support data assimilation for Earth system models
Data assimilation is the combination of the latest observations with a short-range forecast to obtain the best possible estimate of the current state of the Earth system. Machine learning can contribute to it by optimizing the use of satellite observ.....»»
Study finds that colostrum is key to saving beef calves from trouble
In a pair of recent studies, researchers examined risk factors that contribute to insufficient antibody transfer to newborn beef calves, as well as the subsequent negative health effects. They found that the mother's parity (in "heifers" or first-tim.....»»
A new trail to exoplanets: Team successfully detects ammonia isotopologues in atmosphere of cold brown dwarf
They reveal the origin of wine, the age of bones and fossils, and they serve as diagnostic tools in medicine. Isotopes and isotopologues—molecules that differ only in the composition of their isotopes—also play an increasingly important role in a.....»»
Large herbivores such as elephants, bison and moose shown to contribute to tree diversity
Using global satellite data, a research team has mapped the tree cover of the world's protected areas. The study shows that regions with abundant large herbivores in many settings have a more variable tree cover, which is expected to benefit biodiver.....»»
How social media can contribute to species conservation
Photos of plants and animals posted on social media can help protect biodiversity, especially in tropical regions. This is the conclusion of a team of researchers led by the German Center for Integrative Biodiversity Research (iDiv), the Helmholtz Ce.....»»
Apple Research app now lets users share family health history with studies
Apple on Wednesday released a new version of its Apple Research app, which is aimed at letting users contribute to scientific health research using their Apple devices. With version 5.0, users can now share family health history with studies. Read on.....»»
Experiments show molecules, not substrates, are mostly responsible for chirality-induced spin selectivity
A team of chemists at Northwestern University, working with a pair of colleagues from Università di Parma, reports that the chirality-induced spin selectivity (CISS) effect is caused by the molecules involved, not a substrate, when quantum spin is t.....»»
