The Nobel Prize in Physics has been awarded to three scientists for discovering a way to study the world at a level previously thought impossible. The Nobel Assembly announced that Pierre Agostini, Ferenc Krausz and Anne L’Huillier would receive the 2023 prize “for experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter”. “The laureates’ contributions have enabled the investigation of processes that are so rapid they were previously impossible to follow,” the committee announced during a ceremony in Stockholm on Tuesday. Applications for the research include molecular fingerprinting applied to biological samples like blood plasma. By observing minute changes with this technique, it is hoped that in the future it will be possible to detect cancers at a very early stage. The award comes a day after the Nobel Assembly awarded Katalin Karikó and Drew Weissman the Nobel Prize in Physiology or Medicine “for their discoveries concerning nucleoside base modifications that enabled the development of effective mRNA vaccines against Covid-19.” The awards for chemistry, literature, peace and economics are set to be announced between Wednesday, 4 October, and Monday, 9 October.

The human body is a marvel of science and researchers have discovered a strange reoccurring mathematical pattern within its cells. Our bodies are made up of a massive variety of individual cells with countless different functions, from neurons in our nervous system to the oxygen carriers that all work in harmony to keep us alive. Experts from scientific research institutions in Germany, Canada, Spain, and the US have worked together on a study to determine just how many cells of each type there are in the human body and the results are staggering. They found that most adult males possess around 36 trillion cells, while adult females have in the region of 28 trillion cells. For a 10-year-old child, they have around 17 trillion. Interestingly though, scientists discovered that, regardless of the total number of cells, if they are grouped according to their function, the proportions for each individual remain the same. The researchers explained in their findings: “These patterns are suggestive of a whole-organism trade-off between cell size and count and imply the existence of cell-size homeostasis across cell types.” Scientists believe there is a natural balancing act at play between different cell types with new cells being produced to maintain the balance. The body produces fewer larger cells (such as muscle fibres) and more smaller cells (like blood cells). It is hoped that future studies will be able to uncover exactly how this happens and how bodies seem to naturally regulate cells. They explained that all cells are perfectly sized for their roles and any deviation from their scale can indicate the presence of disease. Experts have made their data, analysis and results public in the hopes that future studies into biology will be able to utilise their research.
