While many cannot visit Kyiv,
and perhaps not everyone will be able to even after the war,
I’m honored to be your eyes into my beloved city and country.

It lives.

An infographic titled "The Chemistry of Mulled Wine" explores key chemical compounds in holiday ingredients. It features a central wine bottle surrounded by seven panels. Each panel identifies an ingredient, a key chemical, a molecular structure, and a brief description. Featured pairings include: orange (limonene), lemon (citric acid), sugar (sucrose), wine (ethanol), cloves (eugenol), nutmeg (sabinene), and cinnamon (cinnamaldehyde) for aroma and flavour profiles.

It's #NationalMulledWineDay (no, I don't know why it's in March of all months), so here's a look at some of the key chemicals in this warming drink's components: www.compoundchem.com/2014/12/16/m...

Thoroughly enjoyed the courage skill and great sportsmanship displayed by every Olympian at the #winterolympics from #MilanoCortina2026 and so picturesque too. Great presenting by the BBC team especially Hazel Claire & Jeanette who work tirelessly to make the job look easy, also Crammy Ed & Tim ⭐️🔥☃️🥇

Many congratulations to Huw Nightingale and Charlotte Bankes for their sensational racing today.

Their Gold medal in the Snow Board cross mixed team event at the Milano-Cortina Winter Olympics is the first ever GB gold won on snow at any Winter Olympics

An infographic titled "Compositions of UK Coins" details the metallic makeup of British currency. The £2 coin features a bi-metal design with a copper-zinc-nickel outer ring and a copper-nickel inner circle. The £1 coin shows pre-2017 compositions and notes the 2017 shift to a twelve-sided bi-metal design. The 50p and 20p coins are copper-nickel alloys, with the 50p having been resized in 1997. The 10p, 5p, 2p, and 1p coins all transitioned from copper-based alloys to plated steel in 2011 and 1992.

Infographic detailing the chemistry behind four kitchen chemistry hacks. The first is slowing fruit browning. Fruits brown due to the oxidation and polymerization of phenols. Adding acids, such as lemon juice, wrapping the fruit in cling film or otherwise blocking oxygen slows browning by reducing the activity of the polyphenol oxidase enzyme.

Greetings from Kyiv,
that survived another russian night attack.

2,600 high-rise buildings are now without heating
(in addition to the 1,100 that will remain without it this season).
We still have some.

In a few days, frosts will return.
I don’t know how to make the world listen.
