Today in Chemistry History: Dmitri Mendeleev and the Periodic Table

"Today in Chemistry History" infographic marking Dmitri Mendeleev's birthday (8 Feb 1834). The graphic highlights the date of publication of Mendeleev's first periodic table (1869) and shows the elements that were known at that time and included in the table. It also shows the elements which had yet to be discovered which Mendeleev used his table to predict the properties of.

Today (8 Feb) marks the birthday of Dmitri Mendeleev, one of the best-known chemists. His name is synonymous with the periodic table; though he wasn’t the first to attempt to organise the elements into a table, his use of his own table to predict the properties of undiscovered elements gave him prominence. This graphic looks at the elements known at the time he constructed his table and the elements whose properties he predicted.

World Cancer Day: How antibody–drug conjugates for cancer work

This infographic titled "Antibody-drug conjugates for cancer treatment" explains how ADCs act as "magic bullets" by combining an antibody, a linker, and a cytotoxic drug to target cancer cells. A timeline spans from Paul Ehrlich’s 1910 concept to 2025, noting that 25 ADCs are now approved globally. Diagrams illustrate ADCs binding to cancer cell antigens, entering the cell, and releasing drugs to disrupt DNA or microtubules. Future trends include bispecific ADCs and dual-drug conjugates.

Today (4 Feb) is World Cancer Day. Analysts estimate that there will be 30.5 million new cancer cases diagnosed yearly by 2050, with a projected 18.6 million annual deaths. However, our ability to use medicines to target more effectively is improving, and antibody–drug conjugates are an increasingly effective tool in combating cancers. This graphic explains what they are, how they work, and how they might improve in the future.

Infographic titled “The viruses behind colds and flu.” It explains that adults get 2–5 colds per year and children 7–10, with symptoms peaking after 2–4 days and lasting about 7–10 days. Over 200 viruses cause colds. Rhinoviruses cause 30–50% of colds, coronaviruses 10–15%, influenza viruses 5–15%, and other viruses smaller percentages, with some unknown. Sizes of viruses are shown in nanometres, along with brief notes on transmission, mutation, vaccines, and treatment limits.

This graphic examines the colds that many of us suffer from at this time of year, highlighting the viruses that cause colds and flu and their varying characteristics. Originally published just before the COVID-19 pandemic – remember when we didn’t all know what a coronavirus was? – it continues to be topical with the current surges in flu cases this winter.
