University of Queensland researchers estimate there could be up to 7000 tonnes of microplastics polluting vital ecosystems in Brisbane's Moreton Bay. Dr Elvis Okoffo from UQ's Queensland Alliance for Environmental Health Sciences said the team measured plastic stored within 50 surface sediment samples collected across Moreton Bay.

In Vitro System Bypasses -Complex Technical Setups- of Alternative Approaches And Supports Production Scaling e Interdisciplinary Research Institute of Grenoble (IRIG) , CEA-Leti and fellow European and Canadian institutes and researchers have demonstrated the complete vascularization of organoids on a microfluidic chip at speeds and flow rates similar to blood's, improving functional maturation and enabling their long-term survival.

Researchers gain new insights into how the first cells on Earth were able to use hydrogen gas as an energy source Hydrogen gas (H2) is seen as a key to sustainable energy for the future. Yet it is an ancient form of energy. Even the very first cells on earth lived on H2, which was produced in hydrothermal vents.

Results suggest the clouds of Venus could be hospitable for some forms of life. If there is life in the solar system beyond Earth, it might be found in the clouds of Venus. In contrast to the planet's blisteringly inhospitable surface, Venus' cloud layer, which extends from 30 to 40 miles above the surface, hosts milder temperatures that could support some extreme forms of life.

Research team led by Göttingen University make extremely fast, precise images for first time From solar panels on our roofs to the new OLED TV screens, many everyday electronic devices simply wouldn't work without the interaction between light and the materials that make up semiconductors. A new category of semiconductors is based on organic molecules, which largely consist of carbon, such as buckminsterfullerene.

Anyone who wants to produce medication, plastics or fertilizer using conventional methods needs heat for chemical reactions - but not so with photochemistry, where light provides the energy. The process to achieve the desired product also often takes fewer intermediate steps. Researchers from the University of Basel are now going one step further and are demonstrating how the energy efficiency of photochemical reactions can be increased tenfold.

Research team redesigns phenoxyl radicals with improved oxidation capacity in the lab. Nature uses enzymes for various metabolic processes. These biological catalysts are extremely efficient. Biomimetic catalysts based on inexpensive starting materials from the laboratory that can reproduce the efficiency of the natural enzymes and can function at ambient conditions are therefore of great interest to research and industry.

Astronomers identified icy compounds made of complex organic molecules like alcohol and likely acetic acid, using MIRI, which was managed through launch by JPL. What do margaritas, vinegar, and ant stings have in common? They contain chemical ingredients that NASA's James Webb Space Telescope has identified surrounding two young protostars known as IRAS 2A and IRAS 23385.

A new spectroscopy method has been developed at TU Wien: Using a series of laser pusles, chemical analyses can be carried out much faster and more precisely than before. Whether you want to analyze environmental samples in nature or monitor a chemical experiment, you often need highly sensitive sensors that can "sniff out" even tiny traces of a certain gas with extreme accuracy.

Team of researchers at Freie Universität Berlin develops new technique to release and study individual proteins in cells / Study published in "Nature Methods" A research team led by biochemist Professor Helge Ewers from Freie Universität Berlin has developed a new technique for the light-mediated release and investigation of proteins in live cells.

The technology could offer a cheap, fast way to test for PFAS, which have been linked to cancer and other health problems. MIT chemists have designed a sensor that detects tiny quantities of perfluoroalkyl and polyfluoroalkyl substances (PFAS) - chemicals found in food packaging, nonstick cookware, and many other consumer products.

The gastrointestinal tract is already known to researchers as a major storage site for microand nanoplastic particles (MNPs) in the human body. A research consortium consisting of the University of Vienna, the Medical University of Vienna and other partners under the leadership of CBmed GmbH in Graz has now investigated the effects of the tiny plastic particles on cancer cells in the human gastrointestinal tract.

Is it possible to convert CO2 back to fuels or other useful chemicals? Absolutely - but not in a very targeted way just yet. Empa researcher Alessandro Senocrate is looking at defects in materials that will help us achieve this goal. Can we undo the burning of oil, gas and coal? With a renewable source of electricity, some water and a suitable catalyst, the excess CO2 in the atmosphere could become a resource, for example for the production of synthetic fuels, so-called synfuels.

Research team measures individual giant molecules with record-breaking precision By modifying and boosting lab equipment, a team of chemists are able to measure individual molecules with unprecedented precision. This precision relates to being able to tell that one single sugar grain is missing from a full 1 kilogram bag of sugar.

"This is one of the most important works that this research group has done in its history, and that is saying a lot", especially in a team that is able to characterize and synthesize its own carbon n

Scientists at EPFL have decoded the electronic structure of water, opening up new perspectives for technological and environmental applications. There is no doubt that water is significant. Without it, life would never have begun, let alone continue today - not to mention its role in the environment itself, with oceans covering over 70% of Earth.

Hailin Fu found the chemical system that behaves like cell organelles with well-defined segregated areas in a water-based solution by accident. She followed the science to the end though, and she describes her and her colleagues' journey of discovery in a new paper just published in Nature. It is quite rare to see a Nature article, with all'authors on the paper coming from the same institute.

The work will help researchers tune surface properties of perovskites, a promising alternative and supplement to silicon, for more efficient photovoltaics. Perovskites, a broad class of compounds with a particular kind of crystal structure, have long been seen as a promising alternative or supplement to today's silicon or cadmium telluride solar panels.

A research team from McGill and Vanderbilt Universities describes for the first time the mechanism of calcium transmission by ionotropic glutamate receptors, a mechanism that contributes to the cellular processes underlying learning and memory. In a new study , a research team from McGill and Vanderbilt Universities sheds light on the molecular origins of certain forms of autism and intellectual disability.

A chemical compound essential to all living things has been synthesised in a lab in conditions that could have occurred on early Earth, suggesting it played a role at the outset of life, finds a new study led by UCL researchers. The compound, pantetheine, is the active fragment of Coenzyme A. It is important for metabolism - the chemical processes that maintain life.
