Digging into the molecules of fossilized dinosaur eggshells
Dinosaurs roamed the Earth more than 65 million years ago, and paleontologists and amateur fossil hunters are still unearthing traces of them today. The minerals in fossilized eggs and shell fragments provide snapshots into these creatures' early liv.....»»
NMR spectroscopy method provides faster way to determine chiral structure of molecules
Researchers from Karlsruhe Institute of Technology (KIT) and Voxalytic GmbH have developed a new method that allows, for the first time, the elucidation of the chiral structure of molecules—the exact spatial arrangement of the atoms—by nuclear ma.....»»
Large theropod dinosaurs thrived near South Pole, Australian tracks show
A discovery of dinosaur tracks on Australia's southern coast—dating back to the Early Cretaceous when Australia was still connected to Antarctica—indicates that large theropod dinosaurs thrived in this polar environment, prowling the river floodp.....»»

Researchers develop molecular biosensors that only light up upon binding to their targets
Biosensors—devices that use biological molecules to detect the presence of a target substance—have enormous potential for detecting disease biomarkers, molecules-in-action in diverse biological processes, or toxins and other harmful substances in.....»»
Chemists achieve PFAS-free synthesis of fluorinated pharmaceutical and agrochemical compounds
Chemists at the University of Amsterdam have developed a method to furnish a range of molecules with a trifluoromethyl group attached to a sulfur, nitrogen or oxygen atom. Their procedure, which is published in Science, avoids the use of PFAS reagent.....»»
Chiral molecule research achieves near-complete separation in quantum states
In a study titled "Near-complete chiral selection in rotational quantum states" published in Nature Communications, the Controlled Molecules Group from the Molecular Physics Department of the Fritz Haber Institute has made a significant leap forward.....»»
Closing the RNA loop holds promise for more stable, effective RNA therapies
New methods to shape RNA molecules into circles could lead to more effective and long-lasting therapies, shows a study by researchers at the University of California San Diego. The advance holds promise for a range of diseases, offering a more enduri.....»»
Controlling molecular electronics with rigid, ladder-like molecules
As electronic devices continue to get smaller and smaller, physical size limitations are beginning to disrupt the trend of doubling transistor density on silicon-based microchips approximately every two years, according to Moore's law. Molecular elec.....»»
Microscopic fossilized shells reveal ancient climate change patterns
At the end of the Paleocene and beginning of the Eocene epochs, between 59 to 51 million years ago, Earth experienced dramatic warming periods, both gradual periods stretching millions of years and sudden warming events known as hyperthermals......»»
Matching dinosaur footprints found on opposite sides of the Atlantic Ocean
An international team of researchers led by SMU paleontologist Louis L. Jacobs has found matching sets of Early Cretaceous dinosaur footprints on what are now two different continents......»»

For over a decade, scientists have made extraordinary progress on the long-held dream of fabricating an entire cell from nonliving molecules and materials......»»
Ultra-sensitive photothermal microscopy technique detects single nanoparticles as small as 5 nm
The detection of individual particles and molecules has opened new horizons in analytical chemistry, cellular imaging, nanomaterials, and biomedical diagnostics. Traditional single-molecule detection methods rely heavily on fluorescence techniques, w.....»»
New "chiral vortex" of light allows chemists to "see" molecules through the mirror
An entirely new structure of light is helping to measure chirality in molecules more accurately and robustly than ever before, in a major potential step for the pharmaceutical industry......»»
Researchers synthesize molecular aggregates for solar energy applications
No molecule stands alone—they need others, at least when it comes to being able to display useful photophysical, electronic, and chemical properties. When individual molecules combine into an aggregate, or a complex of two or more molecules, they b.....»»
Chemists succeed in upscaling a common reagent for industrial level applications
The metallic element samarium, when bound with other elements, is an incredibly useful chemical reagent for synthesizing molecules that can lead to new pharmaceuticals. Discovered in a Russian mine in 1879, the element was named after the mineral it.....»»
A small molecular glue that increases P53 level and suppresses tumor growth in vivo
Molecular glues are typically small chemical molecules that act on the interface between the target protein and the degradation machinery to trigger ternary complex formation. Identification of molecular glues is challenging, and there has been a lac.....»»
