Scientists have the intelligence to discover new microbes in Earth's deep soil but not the common sense to leave them there

phys.org/news/2025-04-scientis

phys.orgScientists discover new microbes in Earth's deep soilScientists have discovered a new phylum of microbes in Earth's Critical Zone, an area of deep soil that restores water quality. Ground water, which becomes drinking water, passes through where these microbes live, and they consume the remaining pollutants. The paper, "Diversification, niche adaptation and evolution of a candidate phylum thriving in the deep Critical Zone," is published in the Proceedings of the National Academy of Sciences.

IL1α Boosts Liver Organoid Growth in Hypoxia

Summary: Researchers at The University of Tokyo found placenta-derived IL1α significantly enhances human liver organoid growth under hypoxic conditions, growing up to five times larger. This breakthrough, published in Nature Communications, could advance organoid scalability and functionality in regenerative medicine.

Measuring Mucus by Dragging Dead Fish

A fish‘s mucus layer is critical; it protects from pathogens, reduces drag in the water, and, in some cases, protects against predators. But little is known about how mucus could affect terrestrial locomotion in species like the northern snakehead, which can breathe out of the water and move across land. So researchers explored the snakehead’s mucus layer by measuring the force required to drag them (and two other non-terrestrial species) across different surfaces.

The team tested the same, freshly euthanized fish twice: once with its mucus layer intact and again once the mucus was washed off. Unsurprisingly, the fish’s friction was much lower with its mucus. But they also found that the snakehead was slipperier than either the scaled carp or the scale-free catfish. The biologists suggest that the snakehead could have evolved a slipperier mucus to help it move more easily on land, thereby extending the distance it can cover.

As a fluid dynamicist, I think fish mucus sounds like a great new playground for the rheologists among us. (Image and research credit: F. Lopez-Chilel and N. Bressman; via PopSci)

I started a part-time job at NYMC sequencing core past Oct. PI here (Ravi Sachidanandam) didn't pay me until late Jan, and is now arguing I shouldn't be paid for earlier period since I wasn't present full-time.

And now it looks like 'official' job contract only covers work from late November onward and he was just lying about backpay.

I don't even care about the money - but I would like to get a warning out there about this lab. What would be a good way for this?
