Today is DNA day, marking the date on which the structure of DNA was published. This graphic gives an overview of the structure: www.compoundchem.com/2015/03/24/d...
Infographic on the structure of DNA. DNA has a sugar-phosphate backbone with a set of four different bases holding its two strands together. DNA acts as a code for building proteins. An enzyme transcribes it into mRNA, which carries the code out of cell nuclei, then ribosomes build proteins from the code.

Ever wondered about the science behind the seasoning of cast-iron pans and how it makes them non-stick? The latest edition of Periodic Graphics in @cenmag.bsky.social takes a look: cen.acs.org/food/food-sc...
Infographic on the chemistry of cast-iron cookware. Food sticks to pans because chemical bonds form between the food and the pan. Foods high in protein are particularly susceptible to sticking because the proteins form complexes with metal atoms. Cast-iron pans are made from an alloy of iron, carbon, and silicon. These pans owe their nonstick properties to the seasoning process, which involves applying a thin layer of oil to the pan and baking it in an oven at high temperature several times. The oil polymerizes in the high temperature and stops food from sticking by making the surface of the pan smoother and repelling water. Oil triglycerides in oil contain fatty acids, which have long hydrocarbon chains. At the high temperature used for pan seasoning, hydrocarbon chains break down. Carbon-carbon double bonds in the chains polymerize to form large and complex polymer molecules that stick to the pan. Oils high in unsaturated fats contain more carbon-carbon double bonds.

Infographic on the chemistry of Guinness. As well as bubbles of carbon dioxide, Guinness contains smaller bubbles of nitrogen which lessen the bitter taste and make the head of the beer last longer. The bitterness of Guinness comes from iso-alpha-acids, produced from hops during boiling. The colour of Guinness is due to melanoidins, polymeric structures created during the malting process.
