Walking in nature reduces activity in the brain region linked to sadness and rumination.

A psychologist on why active rest periods—not couch time—are what actually restore us during the holidays. buff.ly/RxJjMbO
Rest is essential during the holidays, but it may mean getting active, not crashing on the couch
Unwinding can be hard during the holidays for many reasons. Building in time to recharge through active leisure can help.

Science has named the seemingly unstoppable growth of renewable energy worldwide as the 2025 Breakthrough of the Year.

Qianjiadong Reservoir in southern Hunan, China, produces a double harvest: solar energy and yellow carp. The solar farm produces up to 80 megawatts of power while the fish forage beneath the panels. With a massive scale-up of solar and wind at home and cheap exports of the technology, China is driving a worldwide surge of renewable energy—Science’s 2025 Breakthrough of the Year.

Important insights into impacts of tropical cyclone: “The results were striking. Risks of dying from various causes consistently increased after a tropical cyclone. Generally, the risk peaked within the first two weeks of the cyclone, followed by a rapid decline”

Ecology Matters: Conversations with Australian Ecologists

Australia’s ecologists share why nature matters across 30 essays with stunning photos – from ants & Antarctic mosses, to wallabies & waterways, to frogs & fungi. www.publishing.csiro.au/book/8205

@ecolsocaus.bsky.social
Ecology Matters
Australia is known for its spectacular and diverse natural environment, from sweeping landscapes to unique flora and fauna. It is a place that invokes wonder and demands protection in equal measure. Its ecology matters, as do the people who have dedicated their careers to understanding it – ecologists. But what do ecologists do? How do they end up studying strange and obscure species? What is it like to work in remote and unusual environments? What happens when disaster strikes? And what are their hopes and concerns for the future? In Ecology Matters, Australia’s preeminent ecologists explain why nature truly matters across 30 enlightening essays. Learn about crayfish and climate change, seed banks and seagrass restoration, floods and fire ecology, ants and Antarctic mosses, whales, waterways and wallabies, and frogs, feral cats and fungi. Featuring interviews with students, Indigenous rangers, restoration ecologists and leaders in the field, this collection of conversations spans the breadth and diversity of Australian ecology. Accompanied by spectacular images from around Australia, many captured by ecologists in the course of their work, Ecology Matters showcases a unique perspective of Australian nature.

Can you spot the lifer (new bird seen in one’s life) I saw in my neighbourhood this morning tiptoeing through the reeds? It’s a pale-vented bush-hen enjoying the post-storm puddles everywhere .. fortunately my partner recognised its loud call #BirdWatching #wildoz #qld
Tall green reeds in most of image but in the centre is the dark brown head with dark eye and yellow-olive bill with vermillion patch on top. Body just visible of a secretive pale-vented bush-hen with pale yellowish legs barely visible among the reeds. Bird has a loud piping call but is not often seen in the open.

Up to 59% of Antarctic ice shelves may be at risk of disappearing under high-emission scenarios by 2300, according to an analysis of the effect of ocean warming in Nature. This could result in up to 10 m of global sea-level rise. go.nature.com/47Ag4k1 🌊 🧪
This is figure 1, which is a schematic of the processes that contribute to the Antarctic ice-shelf mass balance.
