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......»»
More aerosol particles than thought are forming over Siberia, finds study
Aerosol particles play a key role in cooling the planet. They can either directly affect how much sunlight ends up on the surface of the Earth or indirectly through cloud formation, to which they contribute. New particles form from a variety of gas m.....»»
Researchers report successful synthesis of specific chiral molecules using rearrangements of simple hydrocarbons
In nature, organic molecules are either left- or right-handed, but synthesizing molecules with a specific "handedness" in a lab is hard to do. Make a drug or enzyme with the wrong "handedness," and it just won't work. Now chemists at the University o.....»»
Researchers discover how atmospheric feldspar dust contributes to cloud formation
Feldspar is a ubiquitous mineral and makes up about half of the Earth's crust. In the Earth's atmosphere, feldspars play a surprisingly important role. Fine powder carried by air influences cloud formation. Water molecules adhere better to feldspar d.....»»
Looking at the sides of molecules: Lateral force microscopy reveals previously unseen hydrogen atoms
Researchers at the University of Regensburg and the Graz University of Technology have shown that hydrogen atoms at the sides of molecules lying on a surface can directly be seen. The study, published in the journal Proceedings of the National Academ.....»»
Chemists develop new approach to inserting single carbon atoms into rings
Molecules with a central ring system play an important role in the search for active ingredients for new pharmaceutical products—and it is important that the rings should have the correct size if the desired product is to be manufactured as efficie.....»»
Researchers engineer skin bacteria that are able to secrete and produce molecules that treat acne
International research led by the Translational Synthetic Biology Laboratory of the Department of Medicine and Life Sciences (MELIS) at Pompeu Fabra University has succeeded in efficiently engineering Cutibacterium acnes, a type of skin bacterium, to.....»»
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......»»
Novel approach uses ionic liquids for diverse aptamer applications
Aptamers, nucleic acids capable of selectively binding to viruses, proteins, ions, small molecules, and various other targets, are garnering attention in drug development as potential antibody substitutes for their thermal and chemical stability as w.....»»
Molecules exhibit non-reciprocal interactions without external forces, new study finds
Researchers from the University of Maine and Penn State discovered that molecules experience non-reciprocal interactions without external forces......»»
Oral peptides: A new era in drug development
For decades, a substantial number of proteins, vital for treating various diseases, have remained elusive to oral drug therapy. Traditional small molecules often struggle to bind to proteins with flat surfaces or require specificity for particular pr.....»»
EVs contribute to delayed vehicle launches
In 2023, 34 percent of all vehicle launches experienced production delays, compared with 5 percent in 2018, said PwC......»»
Scientists create chiral polyoxometalate-based frameworks with enhanced stability and catalytic activity
A team of scientists has created a chiral assembly by blending inorganic polyoxometalates and organic cyclodextrin molecules......»»
Location, location, location: Research reveals the hidden power of intracellular neighborhoods
New findings published in Molecular Cell provide details about the hidden organization of the cytoplasm—the soup of liquid, organelles, proteins, and other molecules inside a cell. The research shows it makes a big difference where in that cellular.....»»
"Goldilocks system" boosts efficiency of nickel-catalyzed reactions
In the search for cheaper, greener alternatives to routinely used precious metal catalysts like palladium, nickel has become an increasingly popular choice in the last two decades for organic chemists assembling fragments of molecules for a variety o.....»»
Human brain cells put much more energy into signaling
Signaling molecules help modulate the brain's overall activity. Enlarge (credit: Westend61) Indian elephants have larger brains than we do (obviously). Mice have a higher brain-to-body mass ratio, and long-finned pilot w.....»»
First observation of how water molecules move near a metal electrode
A collaborative team of experimental and computational physical chemists from South Korea and the United States has made an important discovery in the field of electrochemistry, shedding light on the movement of water molecules near metal electrodes......»»
New technique could make modeling molecules much easier
Much like the humans that created them, computers find physics hard, but quantum mechanics even harder. But a new technique created by three University of Chicago scientists allows computers to simulate certain challenging quantum mechanical effects.....»»
Study: Physicists create giant trilobite Rydberg molecules
Kaiserslautern physicists in the team of Professor Dr. Herwig Ott have succeeded for the first time in directly observing pure trilobite Rydberg molecules. Particularly interesting is that these molecules have a very peculiar shape, which is reminisc.....»»
Computational model captures the elusive transition states of chemical reactions
During a chemical reaction, molecules gain energy until they reach what's known as the transition state—a point of no return from which the reaction must proceed. This state is so fleeting that it's nearly impossible to observe it experimentally......»»
Webb finds icy complex organic molecules around protostars
In the quest to understand how and where life might arise in the galaxy, astronomers search for its building blocks. Complex Organic Molecules (COMs) are some of those blocks, and they include things like formaldehyde and acetic acid, among many othe.....»»
