Nobel prize for three chemists who made molecules "click"
Three scientists from the United States and Denmark were jointly awarded this year's Nobel Prize in chemistry for developing a way of "snapping molecules together" that can be used to design better medicines......»»
Communication between rotors in molecular motor observed for the first time
A pair of chemists at the University of Groningen in the Netherlands, has observed communication between rotors in a molecular motor. In their study, reported in the Journal of the American Chemical Society, Carlijn van Beek and Ben Feringa conducted.....»»
Research team develops protein-based microcapsule for point-of-care diagnostics
Aptamers, the nucleic acid-based biosensors with the ability to bind specific proteins or small molecules, offer a way to identify target molecules without the complexity of analytical apparatuses. While being increasingly used in diagnostic applicat.....»»
Novel RNA- or DNA-based substances can protect plants from viruses, scientists show
Individually tailored RNA or DNA-based molecules are able to reliably fight off viral infections in plants, according to a new study by the Martin Luther University Halle-Wittenberg (MLU) published in the International Journal of Molecular Sciences......»»
How molecular "handedness" emerged in early biology
Molecules often have a structural asymmetry called chirality, which means they can appear in alternative, mirror-image versions akin to the left and right versions of human hands. One of the great mysteries about the origins of life on Earth is that.....»»
Light stimulates a new twist for synthetic chemistry
Molecules that are induced by light to rotate bulky groups around central bonds could be developed into photo-activated bioactive systems, molecular switches, and more......»»
Trapping and excitation of the simplest molecule: Precise measurement matches theoretical predictions
The simplest possible molecule H2+ was one of the very first molecules to form in the cosmos. This makes it significant for astrophysics, but also an important object of research for fundamental physics. However, it is difficult to study in experimen.....»»
Fluorescent protein outshines the competition when imaging cells
Delicate cellular structures and dynamic processes within cells that were hitherto unseen could be revealed by the next generation of a green fluorescent protein developed by chemists at RIKEN......»»
New molecules, inspired by space shuttles, advance lipid nanoparticle delivery for weight control
Inspired by the design of space shuttles, Penn Engineering researchers have invented a new way to synthesize a key component of lipid nanoparticles (LNPs), the revolutionary delivery vehicle for mRNA treatments including the Pfizer-BioNTech and Moder.....»»
Researchers discover cause of initial spike in immune response when pathogens attack plants
When pathogens attack plants, the plant cells almost immediately react. The plant's cells begin to produce different kinds of small molecules called secondary messengers. These messengers travel throughout the cell membrane to begin the process of ac.....»»
Chemists synthesize unique anticancer molecules using novel approach
Nearly 30 years ago, scientists discovered a unique class of anticancer molecules in a family of bryozoans, a phylum of marine invertebrates found in tropical waters......»»
Researchers develop molecules for a new class of antibiotics that can overcome drug resistant bacteria
About a decade ago, researchers in UC Santa Barbara chemistry professor Guillermo Bazan's lab began to observe a recurring challenge in their research: Some of the compounds they were developing to harness energy from bacteria were instead killing th.....»»
The cultural evolution of collective property rights for sustainable resource governance
Community-based natural resource management has been dominated for several decades by the design principles of Nobel Prize laureate Elinor Ostrom. These principles provide guidelines for improving the governance of resource systems, from small-scale.....»»
New synthesis method uses light reaction on a water surface
By forming chemical bonds between atoms, complex molecules such as those needed for medicines, crop protection products, or high-performance materials are prepared using synthetic chemistry. Such synthesis reactions typically require organic solvents.....»»
Programming cells to organize their molecules may open the door to new treatments
Researchers can engineer cells to express new genes and produce specific proteins, giving the cells new parts to work with. But, it's much harder to provide cells with instructions on how to organize and use those new parts. Now, new tools from Unive.....»»
Important molecular pathway for control of aging discovered
One of the ways cells in different kinds of tissue communicate is by exchanging RNA molecules. In experiments with roundworms of the species Caenorhabditis elegans, researchers at the State University of Campinas (UNICAMP) in Brazil found that when t.....»»
SPNS2 found to be directly exporting S1P for signaling, can be inhibited
When an enemy invades, defenders are ferried to the site to neutralize the marauders. In the human body, a protein carrier called SPNS2 transports S1P molecules from endothelial cells to rally immune cell response in infected organs and tissues......»»
Gemini No Longer Requires You to Click the Send Button
When Google pushed out Gemini to Android last week as a potential future replacement for Google Assistant, we all jumped onto it to see if it could be worth switching to. While Google was upfront about the fact that it lacked many Assistant features,.....»»
Discovery of new plant protein fold may be seed for anti-cancer drugs
University of Michigan researchers are celebrating their discovery of a new plant biochemistry and its unusual ability to form cyclic peptides—molecules that hold promise in pharmaceuticals as they can bind to challenging drug targets......»»
Did Eurasia"s dominant East-West axis "turn the fortunes of history"?
Guns, Germs, and Steel (1997) is Jared Diamond's Pulitzer Prize-winning effort to explain the contrasting histories of Native Americans, Africans, and aboriginal Australians vs. Europeans and Asians. One of his intriguing proposals was that Eurasian.....»»
New evidence of independent written language on Easter Island before arrival of Europeans
A team of philologists, chemists, environmental physicists and engineers affiliated with several institutions across Europe has found evidence of an undeciphered script on wooden tablets created on Easter Island that represents an independent writing.....»»
