Deep-sea mining waste in the Clarion-Clipperton Zone may disrupt the ocean's twilight zone food webs by reducing the nutritional quality of particles vital to zooplankton and micronekton.
First study of its kind finds deep-sea mining waste threatens life and foodwebs in the ocean's dim 'twilight zone'
A new study led by researchers at the University of Hawaii (UH) at Mānoa published in Nature Communications is the first of its kind to show that waste discharged from deep-sea mining operations in the Pacific's biodiverse Clarion-Clipperton Zone (CCZ) could disrupt marine life in the midwater "twilight zone"—a vital region 200–1,500 meters below sea level that supports vast communities of zooplankton, tiny animals that serve as the ocean's basic food building blocks.

I find this reassuring. LLMs don't replace the need to learn how to write whatsoever.

There really are no shortcuts to thinking super hard for many hours. That is the only wait to do good science. All shortcuts are an illusion.

Have you ever looked at some differentially occurring gene clusters in a microbial #pangenome and thought to yourself "I wonder if they contribute to any metabolic modules"?

Hydrogen sulfide production distinguishes Salmonella from close relatives, but its biological significance remains obscure. This study uncovers the secret: Salmonella uses hydrogen sulfide production as a weapon to outcompete E. coli and gain a foothold in the gut.

Reconstructing long-range axons from dense brain images is tough.

This study introduces a novel method that separates axon identification from global statistical rules, showing big improvements over existing tools for mapping neuronal projections.

The final paper from my PhD project is out! Check it out for lots of live recordings of regenerating limbs.

We show how we optimized long-term live imaging of regenerating crustacean limbs, up to 10 days, with high temporal resolution.

#microscopymonday #regeneration #liveimaging
Latest paper elifesciences.org/articles/107... closes an important cycle in our efforts to study regeneration: week-long recordings allow us to observe the behaviour of cells during the entire course of regeneration in a crustacean leg – bright objects in movie are fluorescent nuclei of cells. 1/6
