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......»»
Molecular crystal motors move like microbes when exposed to light
At first glance, Rabih O. Al-Kaysi's molecular motors look like the microscopic worms you'd see in a drop of pond water. But these wriggling ribbons are not alive; they're devices made from crystallized molecules that perform coordinated movements wh.....»»
How DHX9 stress granules protect daughter cells from UV-induced RNA damage
During the process of cell division, new daughter cells inherit a mix of genetic material and other molecules from their mother cells. This inheritance includes both beneficial components, which can help them for a robust start in life, and potential.....»»

Not just a lodger: Novel host-guest assembly provides enhanced reactivity
By design, synthetic molecules typically have specific jobs to prevent or accelerate reactions between other molecules. To help control more complicated reactions, researchers may harness spare space in one molecule to synthesize another chemical str.....»»
Photon-like electrons in a four-dimensional world discovered in a real material
Dirac electrons were predicted by P. Dirac and discovered by A. Geim, both of whom were awarded the Nobel Prize in Physics in 1933 and in 2010, respectively. Dirac electrons behave like photons rather than electrons, for they are considered to have n.....»»
Space company develops centrifuge to test impact of gravity on crystalline-structured drug molecules
Kanjakha Pal and Adrian Radocea, a pair of engineers at Varda Space Industries, a company working to develop space-based drug facilities, has developed a centrifuge-based device to test the impact of gravity on crystalline-structured drug molecules a.....»»
How to upcycle low-energy light: A new design for highly efficient conversion materials
To combine two low-energy photons into one high-energy photon efficiently, the energy must be able to hop freely, but not too quickly, between randomly oriented molecules of a solid. This Kobe University discovery provides a much-needed design guidel.....»»
Webb finds ethanol and other icy ingredients for new worlds
An international team of astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered a variety of molecules, ranging from relatively simple ones like methane to complex compounds like acetic acid and ethanol, in early-stage protosta.....»»
New computational strategy boosts the ability of drug designers to target proteins inside the membrane
Hitting targets embedded within the cell membrane has long been difficult for drug developers due to the membrane's challenging biochemical properties. Now, Scripps Research chemists have demonstrated new custom-designed proteins that can efficiently.....»»
Video: Complex chemistry in the cold depths of space
For years, scientists thought some complex molecules could only be formed on Earth......»»
Scientists develop deep learning method to design bilin-binding proteins
David Baker's group at the University of Washington, Seattle, U.S., have developed a novel deep learning method, RoseTTAFold All-Atom (RFAA), for prediction and design of complexes of proteins, small molecules, and nucleic acids. Subsequently, they d.....»»
Quantum-mechanical "molecules" spotted in superconducting devices
Electronic states that resemble molecules and are promising for use in future quantum computers have been created in superconducting circuits by physicists at RIKEN......»»
New biology unveiled for fundamental cellular machinery
Cellular communication relies on receptor molecules on the cell surface. The periodic uptake and sorting of these receptors, critical for their degradation or recycling, are governed by an elaborate machinery prominently featuring the Commander compl.....»»
Saturn"s moon is a testing ground to gain a better understanding of the methane molecule
Titan is the second-largest moon in the solar system and the only one with a dense atmosphere. At the top of this atmosphere, rich in nitrogen and methane, the sun's radiation produces a great diversity of organic molecules, some of which we also fin.....»»
Ultraviolet spectroscopy: A leap in precision and accuracy at extremely low light levels
Ultraviolet spectroscopy plays a critical role in the study of electronic transitions in atoms and rovibronic transitions in molecules. These studies are essential for tests of fundamental physics, quantum-electrodynamics theory, determination of fun.....»»
Scientists use a new type of nanoparticle that can both deliver vaccines and act as an adjuvant
Many vaccines, including vaccines for hepatitis B and whooping cough, consist of fragments of viral or bacterial proteins. These vaccines often include other molecules called adjuvants, which help to boost the immune system's response to the protein......»»
Chemists break barriers and open up super-resolution molecule mass analysis
A team of chemists led by Prof. Albert Heck puts a new spin on analyzing and understanding molecules. By ingeniously improving current measuring equipment, the team was able to trap and observe individual molecules for a much longer period—up to 25.....»»
