A remote wind...

"Astronomers may have glimpsed a long-predicted wind of gas blowing out from Sagittarius A*", the Milky Way’s central black hole.

Seven of nine "planetary boundaries" have been crossed: this is worrying.

"Earth has breached a critical boundary for ocean acidification, with potentially grim effects for ocean ecosystems and human livelihoods."

About DESI results.
"Dark energy has been a profound puzzle since its discovery 25 years ago. [...] Some physicists are now wondering if they may have gotten a new clue to dark energy’s true nature."

Could dark energy be changing over time?

DESI has made a large 3D map of our universe to study dark energy. These two “fans”—with Earth at the center—correspond to the primary areas DESI has observed, above and below the plane of our Milky Way. Bluer points indicate more distant objects.

The adaptive function and biological importance of social relationships.

The Greek island of Santorini, famed for its jagged cliffs, got its current shape from a cataclysmic volcanic eruption around 1600 B.C.E. New research uses seismic data from a recent swarm of earthquakes to map the volcanic plumbing beneath Santorini.

Colors of #autumn

Some years ago, walking into the woods, I noticed the trunk of a dead tree, hosting a lot of saprophytes. Not far from it, I saw this wonder.

"Smoke from extreme #wildfires in Canada adversely affected air quality in many regions in 2023."

Read here about how important and worrying long-range PM2.5 pollution and the health burden due to large wildfires in a single year can be.

I love Colorado. I went to the Rocky Mountain National Park twice, in 2016 and 2017. Wonderful hikes!

We urgently need more sustainable use and protection of marine ecosystems.

Read about "the intensity of 10 different types of human-caused pressure, including the effects of #climate change, fishing, and pollution, across the global oceans".

Fig. 1. Current and future cumulative impacts on marine habitats.
(A) Current cumulative impacts (2010 to 2020) for 10 pressures on 20 marine habitats. (B) Future projected cumulative impacts (2040 to 2060) with values capped at 1.5. (C) Change in impacts (future minus current) with values capped between –0.1 and 1.0. (D) Hotspots of change were determined by identifying regions with current pressures and change in pressure for the <20th (lower and/or stable) and >80th (higher and/or faster) quantiles. Maps are at 10-km resolution. Figures represent scenario SSP2-4.5, with SSP5-8.5 results provided in fig. S3. Capping values mitigated the visual skew resulting from a few outliers that accounted for <0.01% of raster cells.
