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......»»
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.....»»
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.....»»
How do oceans start to close? New study suggests the Atlantic may "soon" enter its declining phase
A new study, resorting to computational models, predicts that a subduction zone currently below the Gibraltar Strait will propagate further inside the Atlantic and contribute to forming an Atlantic subduction system—an Atlantic ring of fire. This w.....»»
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......»»
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......»»
Nanomedicine paves the way for new treatments for spinal cord injury
In a study published in Advanced Materials, researchers have demonstrated that an innovative nano-vector (nanogel), which they developed, is able to deliver anti-inflammatory drugs in a targeted manner into glial cells actively involved in the evolut.....»»
Microscopy method overcomes the traditional resolution limit for the fast co-tracking of molecules
Researchers at Ludwig Maximilian University (LMU) have developed an innovative method to simultaneously track rapid dynamic processes of multiple molecules at the molecular scale......»»
Exploring the effect of ring closing on fluorescence of supramolecular polymers
In supramolecular chemistry, the self-assembly state of molecules plays a significant role in determining their tangible properties. Controlling the self-assembled state has garnered significant attention as it can be exploited to design materials wi.....»»
Scientists identify water molecules on asteroids for the first time
Using data from the retired Stratospheric Observatory for Infrared Astronomy (SOFIA)—a joint project of NASA and the German Space Agency at DLR—Southwest Research Institute scientists have discovered, for the first time, water molecules on the su.....»»
Helium droplets capture double water structure
An elusive structure involving two water molecules, which had been predicted but never observed, has been isolated by RIKEN chemists. This finding could have implications for a wide range of fields ranging from astrochemistry to corrosion of metals......»»
Understanding the chemical communication between cells
Like the people they make up, cells communicate by bumping into one another and exchanging handshakes. Unlike people, cells perform these handshakes using the diverse range of sugar molecules coating their surface like trees covering a landscape. Han.....»»
Researchers discover cosmic dust storms from Type 1a supernova
Cosmic dust—like dust on Earth—comprises groupings of molecules that have condensed and stuck together in a grain. But the exact nature of dust creation in the universe has long been a mystery. Now, however, an international team of astronomers f.....»»
Probing proton pumping: New findings on protein folding in bacteriorhodopsin
When it comes to drug development, membrane proteins play a crucial role, with about 50% of drugs targeting these molecules. Understanding the function of these membrane proteins, which connect to the membranes of cells, is important for designing th.....»»
Beyond cells: Unveiling the potential of genetic circuits on single DNA molecules
In a new Nature Communications study, researchers have explored the construction of genetic circuits on single DNA molecules, demonstrating localized protein synthesis as a guiding principle for dissipative nanodevices, offering insights into artific.....»»
How molecular systems at the origin of life may have evolved: Rise of the nanomachines
By attaching molecules together, scientists at Université de Montréal think they've found how molecular systems at the origin of life evolved to create complex self-regulating functions......»»
Structural isomerization of individual molecules using a scanning tunneling microscope probe
An international research team has succeeded for the first time in controlling the chirality of individual molecules through structural isomerization. The team, led by NIMS, the Osaka University Graduate School of Science and the Kanazawa University.....»»
New findings explain how soil traps plant-based carbon
When carbon molecules from plants enter the soil, they hit a definitive fork in the road. Either the carbon gets trapped in the soil for days or even years, where it is effectively sequestered from immediately entering the atmosphere. Or it feeds mic.....»»
Currently stable parts of East Antarctica may be closer to melting than anyone has realized
In a warming climate, meltwater from Antarctica is expected to contribute significantly to rising seas. For the most part, though, research has been focused on West Antarctica, in places like the Thwaites Glacier, which has seen significant melt in r.....»»
