State of the Art Imaging Challenges Our Understanding of How Platelets...

Platelets are uniquely mammalian cells, and are the small cells of the blood that are critical for us to stop bleeding when we cut...
Clever bees

Clever Bees Can Identify Different Flowers by Patterns of Scent

Flowers have lots of different patterns on their surfaces that help to guide bees and other pollinators towards the flower’s nectar, speeding up pollination. These...

Rising CO2 May Increase Dangerous Weather Extremes, Whatever Happens to Global...

The paper, published today in Nature Climate Change, demonstrates that higher atmospheric CO2 concentrations directly increase temperature and rainfall extremes, meaning there could be...
antibiotics

Predicting the Outcome of the Arms Race Between Man and Bacteria

Growing resistance to antibiotics is a one of the most serious global health threats we are facing. There is an urgent need to develop...
