Commercial Dishwashers Destroy Protective Layer in Gut
Commercial Dishwashers Destroy Protective Layer in Gut
Residue from rinse agents is left behind on dishes after they are cleaned in professional-grade dishwashers. This damages the natural protective layer in the gut and can contribute to the onset of chronic diseases, as demonstrated by researchers working with organoids at the Swiss Institute of Allergy and Asthma Research.

New method for "capturing" changes in chemical bonds due to electronic dynamics
An international collaboration involving the Autonomous University of Madrid (UAM) has succeeded in bringing X-ray photoelectron spectroscopy to the femtosecond time scale. This advance, published in Nature Communications , will not only make it possible to investigate the effects on chemical bonds due to the movements of atomic nuclei, but also those caused by electronic dynamics.

U-M team recycles previously unrecyclable plastic
PVC, or polyvinyl chloride, is one of the most produced plastics in the United States and the third highest by volume in the world. Study: Using waste poly(vinyl chloride) to synthesize chloroarenes by plasticizer-mediated electro(de)chlorination PVC makes up a vast amount of plastics we use on a daily basis.

Organic cation transporters: study provides insights for the first time
Monoamines are neurotransmitters in the central and peripheral nervous systems and they also transmit signals between cells and the brain. This transmission is followed by their reuptake into the cells by means of transporters. While the specific monoamine transporters have already been well studied, not enough is known about the organic cation transporters, which are high-capacity monoamine transporters.

Iteroselectivity: the selectivity that organic chemistry was missing
Iteroselectivity: the selectivity that organic chemistry was missing
A new type of selectivity to better describe reactivity in organic chemistry has been conceptualized. Researchers from the Laboratory of Organic Chemistry (LCO - ULB) have published their work in Cell Reports Physical Science. An important part of organic chemistry consists of the synthesis of products via a sequence of chemical reactions.

To Battle Climate Change, Scientists Tap Into Carbon-Hungry Microorganisms for Clues
Scientists at Lawrence Berkeley National Laboratory ÜBerkeley Lab) have demonstrated a new technique, modeled after a metabolic process found in some bacteria , for converting carbon dioxide (CO2) into liquid acetate, a key ingredient in "liquid sunlight" or solar fuels produced through artificial photosynthesis.

How to fire projectiles through materials without breaking anything
How to fire projectiles through materials without breaking anything
When charged particles are being shot through ultra-thin layers of material, sometimes spectacular micro-explosions occur, sometimes the material remains almost intact. This has now been explained at the TU Wien. It sounds a bit like a magic trick: Some materials can be shot through with fast, electrically charged ions without exhibiting holes afterwards.

Possible organic compounds found in Mars crater rocks
Possible organic compounds found in Mars crater rocks
Rock samples from the Jezero crater analysed by the Perseverance rover show evidence of liquid water and signatures that could be organic compounds. A study published in Science analyses multiple rocks found at the bottom of Jezero Crater on Mars, where the Perseverance rover landed in 2020, revealing significant interaction between the rocks and liquid water.

Unraveling the secrets of microplastics released by tires
Unraveling the secrets of microplastics released by tires
In Switzerland, tire and road wear particles are one of the biggest sources of microplastics released into the environment, yet the chemical compounds contained in those particles - and their effects - remain largely a mystery. To remedy that knowledge gap, scientists at EPFL and two other Swiss research institutes are conducting a study of the toxicity of tire-particle compounds and how readily they're absorbed by living organisms.

Chemicals could undercut global plastics treaty
Chemicals could undercut global plastics treaty
Next week the UN intergovernmental negotiating committee (INC) on plastic pollution will meet in Uruguay to develop an international legally binding instrument against plastic pollution. There is concern among scientists that the negotiations will overlook the diversity and complexity of chemicals present in plastics.

World's oldest meal offers food for thought
World’s oldest meal offers food for thought
The contents of the last meal consumed by the earliest animals known to inhabit Earth more than 550 million years ago has unearthed new clues about the physiology of our earliest animal ancestors, according to scientists from The Australian National University (ANU). Ediacara biota are the world's oldest large organisms and were first discovered in the Ediacara Hills in South Australia's Flinders Ranges.

Can a new technique for capturing 'hot' electrons make solar cells more efficient?
Can a new technique for capturing ’hot’ electrons make solar cells more efficient?
A Bath discovery opens a new route for measuring and controlling hot electrons. The hope is that more energy will be available to power solar cells. A new way of extracting quantitative information from state-of-the-art single molecule experiments has been developed by physicists at the University of Bath.

Elusive carbonic acid: it really exists!
Elusive carbonic acid: it really exists!
Neutrons from FRM II expose crystal structure of carbonic acid The existence of carbonic acid has long been the subject of debate: theoretically real, but practically impossible to detect. That is because the compound decomposes at the Earth's surface. A German-Chinese team of researchers working at the FRM II Research Neutron Source at the Technical University of Munich (TUM) has now made the crystalline structure of carbonic acid molecules visible for the first time.

Liver cancer: How liver cells go astray
Liver cancer is one of the most deadly types of cancer. A team of University of Basel researchers has now uncovered how a healthy liver cell turns into a tumor cell. Comprehensive metabolic changes convert mature liver cells into immature progenitor cells. These cells proliferate rapidly and tumors develop.

Problem solved in organic chemistry
Problem solved in organic chemistry
In chemicals used in agriculture, as well as in pharmaceuticals and a variety of materials, pyridines are often found as so-called functional units which decisively determine the chemical properties of substances. Pyridines belong to the group of ring-shaped carbon-hydrogen (C'H) compounds ("heterocycles"), and they contain a nitrogen atom (N).
