A fascinating insight into all the weird and wonderful ideas people used to have about health 👇🥼 But don't forget your reading 👓 - I found the light rather dim making it tricky to see the details. #history #health #cambridge 🧪📚🔎

Such fun working with @bas.ac.uk and @ucl.ac.uk colleagues on this paper! Started as coffee table discussion about where the #Antarctic boulders came from. Ended bringing together geology, geomorphology and geophysics 🪨🔬🛩️ Def more than the sum of their parts! 👇 www.bas.ac.uk/media-post/h... 🧪❄️🥼

Hidden giant granite discovered beneath West Antarctic Ice Sheet - British Antarctic Survey

Pink granite boulders scattered across the dark volcanic peaks of the Hudson Mountains in West Antarctica, have revealed a vast buried granite body.

Heat waves are becoming more dangerous as temperatures and humidity rise. For healthy adults, the critical threshold for safe activity is lower than previously thought—around 88°F with 60% humidity. Staying hydrated and finding cooling spaces are key as heat risks intensify.

How hot is too hot for the human body? Our lab found heat + humidity gets dangerous faster than many people realize

New research on young, healthy humans found the body begins overheating when exposed to temperatures and humidity lower than previously believed.
