Science

Graeme Segal's Chern Medal honours the UK's leadership in theoretical physics — cementing historic gender representation gains on mathematics' global stage.

BackgroundThe Chern Medal recognises lifetime achievement in pure mathematics, while the Fields Medals honour outstanding discoveries by researchers under 40. Both prizes represent the highest accolades in global mathematics, shaping academic prestige.

Points
  1. Segal was honoured for a lifetime of work bridging complex topological mathematics with theoretical string theory, cementing the UK's position at the forefront of mathematical physics.
  2. The International Mathematical Union awarded the Fields Medal to 4 researchers under 40, including NYU mathematician Hong Wang, who resolved a 90-year-old geometry problem.
  3. Wang is only the 3rd woman to receive a Fields Medal in its history, highlighting a slow but significant shift in gender representation at the discipline's highest level.

Science

Mapping the genetic causes of severe morning sickness ends decades of psychological misdiagnosis — opening a clear pathway for targeted clinical treatments.

BackgroundHyperemesis gravidarum is a debilitating pregnancy condition that often requires hospitalisation and intravenous fluids. Medical communities historically dismissed the illness as a psychological issue rather than a physical disease.

Points
  1. The global study analysed genetic data from 10,974 women suffering from the condition, bringing the total number of known genetic risk factors to 10.
  2. The newly mapped genes govern metabolic pathways, appetite control, and how the brain processes nausea, pinpointing precise biological mechanisms for future drug development.
  3. The findings validate earlier Cambridge research identifying the fetal hormone GDF15 as a primary driver, confirming that blocking this hormone could prevent severe sickness entirely.
