Toward new degradable polymers
Vinyl polymers, commonly referred to as "plastics," are ubiquitous materials. They are extremely interesting for their ease of synthesis and their great diversity in terms of architecture and functionality.

Scientists make plastic more degradable under UV light
Scientists at Bath found that incorporating sugar units into polymers makes them more degradable when exposed to UV light. Many plastics that are labelled as biodegradable are only compostable under industrial conditions, but scientists at the University of Bath have now found a way to make plastics break down using only UV light.

From the packet into your food: what harmful substances are in food packaging?
Salad boxes to go, sealed-tray lasagna and apple juice in PET bottles: we encounter packaged food and drink everywhere. A new database shows which packaging contains harmful substances that can be transferred to its contents. It also includes findings from researchers at the University of Basel, who are investigating plastic molecules that were previously unknown or barely known.

Nature-inspired self-sensing materials could lead to engineering breakthoughs
The cellular forms of natural materials are the inspiration behind a new lightweight, 3D printed smart architected material developed by an international team of engineers. The team, led by engineers from the University of Glasgow, mixed a common form of industrial plastic with carbon nanotubes to create a material which is tougher, stronger and smarter than comparable conventional materials.

Imaging chemical kinetics at liquid-liquid interfaces
Scientists led by EPFL have developed a new method to measure chemical kinetics by imaging progress of a reaction at a liquid-liquid interface embedded in a laminar-flow liquid microjet. This method is ideal for studies of dynamics on the sub-millisecond timescale, which is very difficult to do with current applications.

Urine treatment: from trial and error to exciting innovation
Worldwide, the demand for fertiliser for agriculture is increasing. This makes the recovery of nutrients from wastewater interesting. Switzerland, for example, is completely dependent on imports for phosphorus. Phosphorus reserves (which are also finite) are controlled by a few countries such as China and the USA.

Love is in the air
More blood flow to the genitals, an increased pulse and dilated pupils: These physical characteristics reveal that a person is sexually aroused. But lust can also be detected in the breath, as a study of an international research team has now shown. According to the study, a characteristic signature of volatile molecules is found in the breath of sexually aroused people.

New mechanism to transfer chirality between molecules in the nanoscale field
If we compare the right to the left hand, we can see these are specular images —that is, like symmetrical shapes reflected in a mirror— and they cannot superimpose on each other. This property is chirality, a feature of the matter that plays with the symmetry of biological structures at different scales, from the DNA molecule to the tissues of the heart muscle.

How equal charges in enzymes control biochemical reactions
Research team led by Göttingen University describes fundamental principle of enzyme catalysis It is well known in physics and chemistry that equal charges repel each other, while opposite charges attract. It was long assumed that this principle also applies when enzymes - the biological catalysts in all living organisms - form or break chemical bonds.

Revolutionary images of the birth of crystals
A team from the UNIGE has succeeded in visualizing crystal nucleation - the stage that precedes crystallization - that was invisible until now. At the interface between chemistry and physics, the process of crystallization is omnipresent in nature and industry. It is the basis for the formation of snowflakes but also of certain active ingredients used in pharmacology.

Chemists use light energy to produce small molecular rings
In the search for new active agents in medicine, molecules whose atoms are linked in rings are becoming increasingly important. Such ring systems have particularly suitable properties for producing such active agents and they are driving the development of innovative treatments for malignant tumours, as well as for neurodegenerative and infectious diseases.

Machine Learning Gets Smarter To Speed Up Drug Discovery
Researchers at Carnegie Mellon University developed a self-supervised learning framework that leverages the large amounts of unlabeled data that other models can't. Predicting molecular properties quickly and accurately is important to advancing scientific discovery and application in areas ranging from materials science to pharmaceuticals.

Planets of binary stars: Targets in the search for alien life
Planetary systems around stars the size of our sun are obvious targets for astronomers trying to locate extraterrestrial life forms, and nearly every second star in that category is a binary star. New research from Denmark and the University of Michigan indicates that planetary systems are formed in a very different way around binary stars-two stars gravitationally bound to each other-than around single stars such as the sun.

Two thirds of chemicals in food packaging not listed for use
The majority of chemicals found in materials that come into contact with food are not intentionally added during the material's manufacturing process and are not currently listed for use, a new systematic evidence map involving researchers at UCL has revealed. Published today in Critical Reviews in Food Science and Nutrition, researchers found evidence for 2,881 food contact chemicals (FCCs) that may transfer into food or drinks from six types of food contact materials (FCM) groups, including plastics, paper and board, metal, multi-materials, glass and ceramic, and 'other'.

How faulty mRNA is detected and destroyed
Two similar proteins can stand in for each other in the quality control mechanism of defective mRNA. This has redefined the distribution of protein tasks / publication in 'The EMBO Journal'. Scientists led by Professor Dr Niels Gehring at the Institute for Genetics at the University of Cologne have investigated two similar proteins, UPF3A and UPF3B, which are involved in the quality control mechanism 'nonsense-mediated mRNA decay' (NMD).

Researchers Transform an Amorphous Solid Into a New Lithium-Ion Battery Material
Researchers at the University of California San Diego and Boise State University have developed a new approach to making novel lithium-ion battery materials. The approach transforms a non-crystalline material into a crystalline one—by cycling it with lithium. Using this approach, the team transformed a non-crystalline (amorphous) material called niobium oxide into a novel crystalline Nb2O5 anode with exceptional lithium storage and fast cycling.

Natural gas could bridge gap from gasoline to electric vehicles, thanks to metal-organic frameworks
As the world turns its attention to electric vehicles as a replacement for gas-powered cars and trucks, some vehicles such as long-haul trucks and planes will need a bridge between gas and electric. Natural gas could be a viable alternative. It's widely available and burns more cleanly than gasoline.
