Writing builds resilience by changing your brain, helping you face everyday challenges

Resilience is often presented as feats of bravery and endurance. But everyday practices like journaling, drafting a text or even writing a to-do list are manifestations of a capacity to adapt.

👀A lovely new stamp design for British Antarctic Territory by my @bas.ac.uk colleague Claire Allen!

Featuring diatoms - tiny algae 🦠 that have beautiful structures and are everywhere, including in toothpaste apparently 😂🪥

More info: www.iompost.com/our-news/ove...

#geology #Antarctica 🧪❄️🌊

Four square images, each showing a stamp. On each stamp is a close-up photograph of a diatom. The top left diatom is a triangular shape and has lots of dots all over it. It is shown on a pale yellowish background. The top right diatom is circular and has "spokes" radiating out from a small central circle. It is shown against a pale pink background. The bottom right diatom is oval and has a leaf-like structure with a line running down the middle like a stem. It is shown against a paleo green background. The bottom left diatom is round and has less fine detail than the other diatoms, with seven lines radiating out from the centre. It is shown against a pale blue background. Each stamp has a silhouette of the King's head in the top right corner.

Your science is sound
Your press release says “Reef recovery”
The internet hears “Crisis over”

A study shows how well-intended optimism can fuel climate misinformation.

Context matters...

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.
