  1. A common insecticide that is a major hazard for honeybees is now effectively detected in honey thanks to a simple new method.
  2. Metabolic robustness, the ability of a metabolic system to buffer changes in its environment, is not always a welcome feature for microbiologists: it interferes with metabolic engineering or prevents that antibiotics kill bacteria. Therefore it is important to understand the mechanisms that enable metabolic robustness. A massively parallel CRISPRi screen demonstrated that E. colimetabolism is very robust against knockdowns of enzymes, and multi-omics data revealed the mechanisms behind it. In the future, the researchers want to apply this knowledge to build better models of metabolism, which enable rational-design of industrial microbes.
  3. Looking for the perfect catalyst is not only about finding the right material, but also about its orientation. Depending on the direction in which a crystal is cut and which of its atoms it thus presents to the outside world on its surface, its behavior can change dramatically.
  4. Sound waves have been part of science and medicine for decades, but the technologies have always relied on low frequencies. Now researchers have revealed how high frequency sound waves could revolutionize the field of ultrasound-driven chemistry.
  5. Inspired by nature, researchers can demonstrate a synthetic strategy to stabilize bio-inspired solar energy harvesting materials. Their findings could be a significant breakthrough in functionalizing molecular assemblies for future solar energy conversion technologies.
  6. The synthesis and self-organization of biological macromolecules is essential for life on earth. Chemists now report the spontaneous emergence of complex ring-shaped macromolecules with low degrees of symmetry in the laboratory.
  7. Multilayer plastic materials are ubiquitous in food and medical supply packaging, particularly since layering polymers can give those films specific properties, like heat resistance or oxygen and moisture control. But despite their utility, those ever-present plastics are impossible to recycle using conventional methods.
  8. Researchers have prepared synthetic protocells coated in red blood cell fragments for use as nitric oxide generating bio-bots within blood vessels.
  9. The vision of the future of miniaturization has produced a series of synthetic molecular motors that are driven by a range of energy sources and can carry out various movements. A research group has now managed to control a catalysis reaction using a light-controlled motor.
  10. Some viruses can get inside cells via a mechanism that involves sulfur organic molecules. Chemists have discovered effective inhibitors and blocked the uptake of SARS-CoV-2.
