Dr Pal Bela Szecsi | Changes in Maternal Vitamin D Levels Throughout Pregnancy and Across the Seasons
Original Article Reference
This SciPod is a summary of the paper ‘Variation in plasma 25-hydroxyvitamin D2 and D3 in normal pregnancy with gestational age, sampling season, and complications: A longitudinal cohort study’ from PLOS One. DOI: https://doi.org/10.1371/journal.pone.0231657
About this episode
Maternal nutrition plays a major role in reducing pregnancy complications and improving infant and child health. Vitamin D is important during pregnancy as it helps the baby’s heart, bones, teeth and nervous system develop properly. Low levels of vitamin D in pregnancy have been linked to a number of problems and conditions. Dr Pal Bela Szecsi and his team at Copenhagen University Hospital in Denmark have been investigating vitamin D concentrations throughout normal pregnancy and in relation to possible complications.

Professor Andrew R. Barron | Repurposing Plastic COVID Facemasks to Improve the Steel-Making Process
Since the beginning of the COVID-19 pandemic, billions of plastic facemasks have been used and disposed of, with the majority destined for landfill. Professor Andrew R. Barron and his team at the Energy Safety Research Institute in Swansea, Wales, have developed an innovative method for repurposing these used facemasks. By transforming them into a powdered material that acts as a reducing agent, Professor Barron’s team aim to make the steel-making process more energy-efficient and sustainable.
Wide-area scans of the sky are an important tool for astronomers as they seek to learn more about the universe. However, as the latest observation techniques have become increasingly sensitive, faint objects within these surveys can appear to blend together. Through his research, Dr Peter Melchior at Princeton University presents a computer-based framework for disentangling these blended sources, and for artificially reconstructing the components they contain. Named SCARLET, the technique could soon help astronomers to study the depths of the observable universe in unprecedented levels of detail.
It may be surprising to know, that you – and all other mammals – are technically cynodonts. The first cynodonts appeared approximately 260 million years ago as small creatures about the size of a house cat. A particular group of cynodonts evolved to become more ‘mammal-like’, eventually evolving into the first true mammals. Dr Jennifer Botha from the National Museum, Bloemfontein in South Africa studies the anatomy and life history of specimens along the cynodont–mammalian transition, to gain key insights into the origins and evolution of mammals.
Dr Dirk Lachenmeier | Avoiding Injury from Hot Food by Determining the Threshold Contact Temperature
Consuming very hot food and beverages poses a risk of oesophageal cancer. Although injury thresholds have been specified in industry standards and guidelines, there remain practical limitations in obtaining an exact measurement of the contact temperature from hot foodstuff in the oral mucosa inside the mouth. Dr Dirk Lachenmeier, a chemist and toxicologist at the Chemical and Veterinary Investigation Agency Karlsruhe, worked in collaboration with his father Dr Walter Lachenmeier, a retired engineer, to develop a new method to estimate the safe surface or consumption temperature of hot food. This has allowed them to make important recommendations.
