Yet, in nature, we observe many differences between individuals. For example, sticklebacks (tiny fish) in the... click to read more
Tobacco smoking and other exposures shut off cancer-fighting genes
Cancer is a genetic disease caused by mutations in DNA. Most mutations are substitutions of single nucleotides, the basic building blocks of DNA. Mutations occur over time due to natural processes like faulty DNA repair or from external sources like ultraviolet light. Researchers have discovered... click to read more
Stacking molecular chips in multiple dimensions
Supramolecular polymers are an alternative to traditional plastics, where monomers or building blocks are held together by weak, reversible interactions. These materials are becoming increasingly relevant due to their valuable properties of recyclability, self-healing or good processability amongst others, and they present numerous promising applications... click to read more
A hidden clock that times cytoplasmic divisions
Omnis cellular e cellula – all cells arise from pre-existing cells. This seemingly obvious tenet of cell theory was only formalized when, in 1841, the Polish embryologist Robert Remak boldly described forms of animal cell division when examining chick embryo red blood cell development. Later,... click to read more
Ammonia Energy: A Call for Environmental Awareness
As the world shifts to low-carbon energy, finding alternatives to fossil fuels is essential. Hydrogen (H2) stands out as a leading candidate because it can be produced in large quantities and used in many ways. Countries representing about 90% of the world's energy supply are... click to read more
