In the absence of a vaccine or highly effective treatments for COVID-19, combining isolation and intensive contact tracing with physical distancing measures—such as limits on daily social or workplace contacts—might be the most effective and efficient way to achieve and maintain epidemic control, according to new modelling research published in The Lancet Infectious Diseases journal.

Vomiting bumblebees show that sweeter is not necessarily better

22 January 2020

Animal pollinators support the production of three-quarters of the world’s food crops, and many flowers produce nectar to reward the pollinators. A new study using bumblebees has found that the sweetest nectar is not necessarily the best: too much sugar slows down the bees. The results will inform breeding efforts to make crops more attractive to pollinators, boosting yields to feed our growing global population.

Women in STEM: Fiona Llewellyn-Beard

28 November 2019

Fiona Llewellyn-Beard is a PhD candidate in the Department of Earth Sciences, where she studies salt marshes and how they store huge amounts of carbon. Here, she tells us about how a childhood love of mud pies led to her current research, her love of the outdoors, and how everything in the environment is interconnected.
