I can't stop admiring this photo by the Artemis II crew made of the moon. (Nikon D5 shot at f 7.1 at 800th of a second on 400 iso at 80 mm)

During the pandemic, the world stood still – and many lakes became measurably clearer. A global study shows that #lockdowns caused water #turbidity in lakes worldwide to drop sharply 🌍💧

This is dystopian… and not just because they’re dressed like a scene from the handmaids tale.

These are mostly children.

This is where Liam Ramos is being held.

They’re screaming “let us out” and protesting the brutal conditions.

These kids are braver than every ICE thug holding them hostages

Does anyone knows if this model can still be found to buy second hand? Or a model with similar characteristics?
It is to be used for aquatic fungi isolations.

Any info would be much appreciated.

Rivers are messy: Beyond the water bias in research and management This article reviews current trends in interdisciplinary river research to argue that a “water bias” or tendency consider rivers as synonymous with water can hinder our understanding of rivers and con...

"Rivers are messy: Beyond the water bias in research and management" — A new article co-authored by @brdemuth.bsky.social combines historical and natural science ways of thinking about rivers to argue for the importance of understanding them as more than simply channels of water.

An infographic showing the progression from underlying causes to environmental impacts across terrestrial, freshwater, and marine ecosystems. The diagram flows left to right through three main sections: "UNDERLYING CAUSES" lists three core issues: Disconnection from and domination over nature and people Concentration of power and wealth Prioritization of short-term, individual and material gains "INDIRECT DRIVERS" includes four categories: Demographic and sociocultural Economic and technological Institutions and governance Conflicts and epidemics "DIRECT DRIVERS" shows relative impact percentages across terrestrial, freshwater, and marine environments, represented by horizontal bars with color-coded segments for: Land/sea use change (purple) Direct exploitation (light purple) Climate change (yellow) Pollution (gray) Invasive alien species (orange) Others (light gray) The right side features a circular illustration divided into terrestrial, freshwater, and marine zones with representative wildlife silhouettes.

🌏 Biodiversity loss has deep-rooted causes—from power imbalances to short-term priorities. These shape indirect & direct drivers like land/sea use change, exploitation & climate change.

Surveying wildlife in a pond with water reeds, amidst farmland, trees, hills, woods in distance.

Often overlooked, small water bodies - streams, damp ditches, small bogs, ponds - support more rare species compared with larger habitats while high-quality ponds support about 2/3 of all freshwater plant + animal species in a landscape.

A braided river in the golden hour sunshine. The river looks almost golden, with brown landscape surrounding it. On the horizon there are some just visible islands underneath a few clouds and bright sky, with the sun just above, out of the shot.

Strands of gold 💛

Not a bad first day back in #Iceland. Pretty windy but managed to get the drone up anyway...

Sunlight drives the abiotic formation of nitrous oxide in fresh and marine waters Nitrous oxide (N2O) is a potent greenhouse gas and the main stratospheric ozone-depleting agent, yet its sources are not well resolved. In this work, we experimentally show a N2O production pathway no...

Very interesting finding: photochemical formation of N2O in freshwater and marine waters.

The N cycle gets more complex. 🧐

We are now starting the second part of the #NFR_HITLICE project on Senja, Northern Norway, where we infect migrating salmon smolts with salmon lice and tag them with acoustic transmitters with predation sensors to investigate the vulnerability to predation 🐟

Environmental exposure levels of antibiotics in global rivers. Total risk quotient is calculated as the sum of individual risk quotients of all 40 antibiotics in the global river system under low-flow conditions.

As consumption of antibiotics has risen around the world, so has antibiotic pollution of rivers. A model identifies the rivers most likely affected and the drugs most likely to be found in the water. In PNAS Nexus: academic.oup.com/pnasnexus/ar...

Switzerland is one of the few countries to have introduced "tertiary" cleaning of sewage. Cleaning the sewage 3 times, removes not only bacteria & viruses but also chemicals & medicines - reducing risk of antibiotic resistant bacteria developing.

A foamy sea breaks on the shore in front of a dark, blue stormy sky. Spray rises towards the heavens. An island on the horizon.

It’s pretty gnarly out there today, so here’s a stormy photo from a few years ago. 📷
