The scans of some rocks in an ancient river -bed showed the present of small nodules and reaction fronts which are rich in minerals that might have formed due to chemical reactions catalyzed by…

8500 meters deep may be the limit for marine bony fish
Trimethylamine oxide (TMAO) helps stabilize proteins in fish at high pressures. It has been found that TMAO concentration in fish that live in wider depth range increases with increasing depth. In deep sea where pressure go upto 1000 times of normal atmospheric pressures, the TMAO levels might be limiting factor. Work published in PNAS predicts 8000-8500…
