This week, the UK has confirmed it plans to fortify non-wholemeal flour with folic acid. It’s not the first country to do so: the United States has been fortifying flour with folic acid since 1998. Most countries in South America and a number in Asia also have mandatory fortification programs. This graphic looks at the reasons for fortification with folic acid – and making it also got me wondering why the practice isn’t more widespread in Europe.
How does COVID spread? Of all the questions about the pandemic, this seems like it would be a fairly simple one to answer. But, even several months into the pandemic, the guidance from public health organisations did not recognise the potential for COVID to be transmitted through the air. The latest edition of the Chem vs. COVID series with the Royal Society of Chemistry highlights the point at which scientists called for this mode of transmission to be more widely recognised.
With the ongoing COVID-19 pandemic, air purification technologies have been receiving renewed attention as workplaces look for solutions that will lower their workers’ risk of exposure. In the latest edition of Periodic Graphics in Chemical and Engineering News, we take a look at the different types of air purification and how each of them works.

On this day (16 June) a year ago, the first effective treatment for COVID-19 was announced. The corticosteroid drug dexamethasone, already used to treat several inflammatory and autoimmune conditions, was found to be effective for patients in a serious condition in hospital with COVID. This discovery was the product of the RECOVERY trial, a programme started in March 2020 to find COVID treatments.
On this day in 2020, the Moderna COVID-19 vaccine entered phase 1 trials, making it the first COVID vaccine to do so. This came less than a week after the World Health Organisation declared COVID-19 a global pandemic. How was it possible for this to happen so quickly? The third part of the #ChemVsCOVID series, produced with the Royal Society of Chemistry, gives a brief overview of the prior work and what the phase 1 trials looked at.
The second part of the #ChemVsCOVID series, produced with the Royal Society of Chemistry, looks at how the structure of the spike protein was determined and how it helped our efforts against the virus.
