Promising anticancer molecule identified
Researchers at Kanazawa University in collaboration with teams from Toyama Prefectural University and BioSeeds Corporation report in ACS Applied Materials & Interfaces the identification of a molecule with enhanced antiproliferative activity in cance.....»»
Direct transformation of CH3Cl to acetic acid through a carbonylation reaction
Methane, the main component of natural gas, shale gas and flammable ice, is a clean and inexpensive chemical feedstock with abundant reserves. Nevertheless, the high C-H band energy and low polarizability of a methane molecule inhibit the utilization.....»»
The non-coding 7S RNA regulates gene expression in human mitochondria
A new study published in the journal Cell shows that a non-coding RNA molecule regulates mitochondrial gene expression in human cells. The work results from a collaboration between the University of Gothenburg and Karolinska Institutet, both Sweden,.....»»
Metallic five-membered ring pushes the boundaries of aromaticity
Researchers at Chemnitz University of Technology, Humboldt Universität Berlin and Philipps-Universität Marburg succeed in synthesizing a molecule that should not actually exist.....»»
Iron catalyst could make important chemical reactions cheaper and more eco-friendly
A catalyst is a key ingredient for many chemical reactions. It facilitates a molecule to change into another molecule, without being changed itself, meaning it can be used multiple times. However, many catalysts are made of precious metals, making th.....»»
Researchers detect a novel binding mechanism between small and gigantic particles
Researchers at the 5th Physical Institute of the University of Stuttgart have verified a novel binding mechanism forming a molecule between a tiny charged particle and a gigantic (in molecular terms) Rydberg atom. The scientists observed the molecule.....»»
Unlocking the secrets of maple syrup, one molecule at a time
Nature conceals a phenomenal number of molecules as varied as they are imperceptible. The plant kingdom is particularly chemically complex......»»
A novel molecular mechanism that regulates secretion of the sonic hedgehog signaling molecule
Research led by Hong Kong University of Science and Technology (HKUST) has revealed a novel mechanism that regulates secretion of sonic hedgehog (Shh), a key signaling molecule that plays an important role in cancer progression in mammals, opening th.....»»
Collisions with electrons cool molecular ions
A lone molecule free in cold space will cool by slowing down its rotation—it will spontaneously lose its rotational energy in quantum transitions, typically only once in many seconds. This process can be accelerated, slowed down, or even inverted b.....»»
New 3D structure could lead to future drugs against cancer
A team of scientists has created a three-dimensional map showing how a small molecule with anticancer properties—called spliceostatin—can promote the killing of cancer cells. This fundamental discovery could ultimately help researchers design fut.....»»
Controlling chemical mirror images
Chirality, while not a rarity in the world of molecules, is nevertheless a special property. If a molecule is chiral (from the Greek word chiros = hand), it exists in two mirrored versions that are very similar but not identical—like two hands that.....»»
Single-molecule techniques illuminate mechanisms of GPCR activation
Scientists at St. Jude Children's Research Hospital and Columbia University/New York State Psychiatric Institute are studying G protein-coupled receptors (GPCRs), membrane proteins that are the target of one-third of approved drugs. Using single-mole.....»»
New molecule sets stage for nickel as a "greener" photocatalyst, reveals key steps in reaction process
In recent years, the golden word in precious metals is palladium......»»
Tuning exact ratios of two metals in a catalyst may enable new directions in catalysis science
In the last 20 years, there have been efforts to reduce fossil fuel use in plastics manufacturing, and, according to Penn State researchers, efficient, customizable catalytic reactions—where two metals are combined using a catalyst, or molecule tha.....»»
Are You the Asshole? New AI Mimics Infamous Advice Subreddit
Two artists are illustrating bias in machine learning with data from one of the most opinionated sites on the internet: the r/AmITheAsshole subreddit. Motherboard reports: Now boasting 3.9 million users, the r/AmITheAsshole subreddit has become known.....»»
Scientists turn a hydrogen molecule into a quantum sensor
Physicists at the University of California, Irvine have demonstrated the use of a hydrogen molecule as a quantum sensor in a terahertz laser-equipped scanning tunneling microscope, a technique that can measure the chemical properties of materials at.....»»
Not quite Le Mans: 24-hour race won by molecule that traveled 1 micron

An Intel chip that mimics the human brain could end up in your next PC
Intel’s neuromorphic Loihi chips could end up in future CPUs though they might also be available as a cloud service......»»
Researchers Create a Magnet Made of One Molecule
Sometimes making a brand-new type of box requires outside-the-box thinking, which is exactly what Spartan chemists used to create an eight-atom, magnetic cube. Phys.Org reports: Part of what made the researchers' idea so wild was their choice to work.....»»
Video: Ariane 6 cryo-arms test mimics liftoff
Europe's Spaceport in French Guiana is preparing for the arrival of Ariane 6, ESA's new heavy-lift rocket. The latest round of testing aims to validate the system of fuel lines and mechanical supporting arms that will keep Ariane 6 topped up with liq.....»»
