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.....»»
LookingGlass Suite enables organizations to identify relevant cybersecurity issues
LookingGlass Cyber Solutions announced the release of LookingGlass Suite, which provides cybersecurity executives and their teams with a more holistic assessment of their organization’s cyber risk by mimicking the adversary’s perspective. The Loo.....»»
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.....»»
