Molecular cooperation at the threshold of life
Molecular cooperation at the threshold of life
Protein-like aggregates known as amyloids can bind to molecules of genetic material. It is possible that these two types of molecules stabilised each other during the development of life - and that this might even have paved the way for the genetic code. How organisms develop from inanimate matter is one of the biggest questions in science.

Artificial intelligence finds ways to develop new drugs
Artificial intelligence finds ways to develop new drugs
A new AI model developed by chemists at ETH Zurich can not only predict where a pharmaceutically active molecule can be chemically modified, but also how best to do it. This makes it possible to identify new pharmaceutical ingredients more quickly and improve existing ones in a targeted manner. New active pharmaceutical ingredients lay the foundations for innovative and better medical treatments.

Chemistry researchers develop a protein capable of eliminating microplastics
Chemistry researchers develop a protein capable of eliminating microplastics
From November 13 to 19, the third Global Plastics Treaty Meeting was held in Nairobi (Kenya), which tried, albeit in vain, to find an agreement to hold "countries and companies accountable for their action, or inaction, on plastic pollution and its impact on our health, environment and economy". World leaders have set themselves a date to further discuss the issue in April 2024 in Ottawa, Canada, but in the meantime, plastics and microplastics continue to produce pollution, primarily in waters around the globe.

New Biodegradable Polymers Traceable Without Toxic Contrast Agents
Polyphosphoesters, molecules containing phosphorus as central element, are easily traceable without the need for contrast agents, thanks to developments by researchers of the University of Twente. Normally, these molecules display a similar molecular composition of our DNA, leading to considerable 'noise' in the image.

Two Conductors of a Chemical Reaction
Two Conductors of a Chemical Reaction
For the first time, researchers at TU Wien have successfully observed the operating principle of so-called promoters in a catalytic reaction in real-time. These promoters play an important role in technology, but so far there is only limited understanding of how they work. Catalysts are essential for numerous chemical technologies, ranging from exhaust gas purification to the production of valuable chemicals and energy carriers.

Putting an End to Plastic Separation Anxiety
Key Takeaways The biology-driven process requires no fancy equipment and yields molecules of a biodegradable plastic alternative that can be made into new commodity products. Initial tests indicate that the process could be successfully applied to real-world plastic streams. In the future, the microbes used to convert the plastic intermediates could also produce other valuable products, enabling a new field of biomanufacturing fed by waste.

Deep within the Earth, Iron Oxide Withstands Extreme Temperatures and Pressures
The core-mantle boundary (CMB) is the interface between the earth's iron metal core and the thick rocky layer of mantle just above the core. It is a world of extremes-temperatures thousands of degrees Fahrenheit and pressures over a million times the pressure at the surface of the Earth. While it may seem far away from our environment on Earth's surface, plumes of material from the CMB can ascend upwards through the planet over tens of millions of years, influencing the chemistry, geologic structure, and plate tectonics of the surface world where we live.

More efficient electrodes for CO2 recycling
More efficient electrodes for CO2 recycling
With the ever-increasing interest in renewable energy, scientists are continuously searching for new technologies to store energy. CO2 electrolysis is a promising way to store energy whilst recycling carbon dioxide. By applying electricity, CO2 and water react and produce more complex molecules. A study published in Nature Communications lead by Hugo van Montfort at TU Delft has presented a new design of electrodes that improves the efficiency of CO2 electrolysis.

’Bouncing’ comets could deliver building blocks for life to exoplanets
How did the molecular building blocks for life end up on Earth? One long-standing theory is that they could have been delivered by comets. Now, researchers from the University of Cambridge have shown how comets could deposit similar building blocks to other planets in the galaxy. It's possible that the molecules that led to life on Earth came from comets, so the same could be true for planets elsewhere in the galaxy Richard Anslow In order to deliver organic material, comets need to be travelling relatively slowly - at speeds below 15 kilometres per second.

Microbes could help reduce the need for chemical fertilizers
New coating protects nitrogen-fixing bacteria from heat and humidity, which could allow them to be deployed for large-scale agricultural use. Production of chemical fertilizers accounts for about 1.5 percent of the world's greenhouse gas emissions. MIT chemists hope to help reduce that carbon footprint by replacing some chemical fertilizer with a more sustainable source - bacteria.

A neural organoid with an immune environment
French, Singaporean and British researchers, led by Prof. Florent Ginhoux, head of a research team at Gustave Roussy/Inserm, have succeeded in demonstrating in a neuronal organoid the role of the brain's immune environment in its formation and development. The development of these three-dimensional structures integrating neuronal cells and the immune environment is, to date, one of the most complete in vitro models of the human brain.

Solar-powered device produces clean water and clean fuel at the same time
Solar-powered device produces clean water and clean fuel at the same time
A floating, solar-powered device that can turn contaminated water or seawater into clean hydrogen fuel and purified water, anywhere in the world, has been developed by researchers. These are the sorts of solutions we will need to develop a truly circular economy and sustainable future Erwin Reisner The device, developed by researchers at the University of Cambridge, could be useful in resource-limited or off-grid environments, since it works with any open water source and does not require any outside power.

Aerosols: When scents influence our climate
One of the great unknowns in climate models is the behavior of certain gases that often smell strongly and cause water to condense. TU Wien (Vienna) is providing new insights into this. It has long been clear that man-made greenhouse gases are changing the climate - but there are still important details of climate change that are not well understood.

Physicists trap electrons in a 3D crystal for the first time
The results open the door to exploring superconductivity and other exotic electronic states in three-dimensional materials. Electrons move through a conducting material like commuters at the height of Manhattan rush hour. The charged particles may jostle and bump against each other, but for the most part they're unconcerned with other electrons as they hurtle forward, each with their own energy.
