The vision system, evolved over millions of years, is highly complex. To make vision sensitive throughout the whole range of visible wavelengths, Nature employs a supramolecular chemistry approach. The visual pigment, cis-retinal, changes its shape upon capturing a photon. This shape transformation is accompanied by changes in the supramolecular organization of the surrounding proteins, subsequently triggering a cascade of chemical signaling events that get amplified and eventually lead to visual perception in the brain. “Some deep-sea fish have evolved antenna-like ...

Approximately one-fifth of the world's electric energy is dedicated to refrigeration, and the International Energy Agency anticipates a twofold increase in the number of air conditioning units by 2040. Despite a century of advancements, existing refrigeration systems, relying on vapour compression, have hit their thermodynamic threshold. These systems not only emit greenhouse gases, contributing to environmental issues, but also produce significant noise. Prioritizing the development of energy-efficient and eco-friendly systems is thus paramount to address global warming ...

Growth is a fundamental biological process and a prerequisite for living organisms to develop and reproduce. The processes of cell growth (i.e. the production of new biomass) and of cell division must be coordinated with each other. In multicellular organisms such as humans, the growth of cells must also be coordinated with their environment so that cells are present in the right number and size to form functional tissue or organs. Cell growth is therefore strictly regulated and takes place only when certain growth signals are present. But cancer cells are different. They grow unchecked, they divide ...
