Another animal in danger

The regenerative feats of endangered axolotls

Axolotls (Ambystoma mexicanum) are a critically endangered species of salamander. The species has only one natural habitat remaining, a series of canals in Mexico City, and only 50 to 1,000 axolotls are estimated to be left living there.

Life is fascinating

Scientists discover first nitrogen-fixing organelle

Modern biology textbooks assert that only bacteria can take nitrogen from the atmosphere and convert it into a form that is usable for life. Plants that fix nitrogen, such as legumes, do so by harboring symbiotic bacteria in root nodules. But a recent discovery upends that rule.

I think I'm reading posts from a person enjoying retirement. Isn't it great to have all this time to look into and share stuff that interests you?

Check out the section on the cleaner wrasse fish. Thought provoking.

Even unicellular and plants show sentient reaction.

How can a plant turn it's leaves toward the sun if it not conscious where it is.

There's no clear evidence to definitively say unicellular organisms are sentient. but they do react to stimulus... It's impossible to differentiate if their responses are due to true awareness or simply sophisticated biological mechanisms... For the moment...

Our understanding of the nature of sentience in simpler forms of life is simply nonexistent.

I'm of those who believe that sentience itself even in the most simple being, is a fundamental property of life.

I agree. Panpsychism philosophy captures this position.

I don’t miss work at all and I’m enjoying retirement immensely . It is indeed great to have all this time to look into stuff that interests me . Even greater to have time to pursue things . The above posts confirm my thoughts on fish . Fish are cool .

Zebra fish help humanity once again

Why zebrafish can regenerate damaged heart tissue, while other fish species cannot

A heart attack will leave a permanent scar on a human heart, yet other animals, including some fish and amphibians, can clear cardiac scar tissue and regrow damaged muscle as adults.

Researcher finds that wood frogs evolved rapidly in response to road salts

When we think of evolution, we think of a process that happens over hundreds or thousands of years. In research published in Ecology and Evolution a team led by Rick Relyea, Ph.D., professor of biological sciences and David M. Darrin Senior Endowed Chair at Rensselaer Polytechnic Institute...
