๐โก Researchers at the University of #Sydney discovered that the breakup of supercontinent Nuna 1.46 billion years ago created shallow continental shelves that provided ideal conditions for complex eukaryotic #life to evolve.
Scientists found these vast shallow seas served as ecological incubators with elevated nutrients and #oxygen levels during #Earth's so-called "Boring Billion" period.

Question for the scientifically-minded:
As an endurance athlete and former #EMT But I have been thinking about this for maybe the past week or so.
Elite marathon runners train at high altitudes where the air is thinner and then run races at lower elevations where the air is denser. But...
What would happen if someone did brutal cardio workouts (assault bike, rowing machine, ski, etc.) in a hyperbaric chamber? How would performance, anaerobic fatigue, endurance be impacted? Nothing more than 2 ATA (66 feet-salt water) to start.
Understanding the blood and muscle tissue would be highly saturated with O2, far more than what hemoglobin would normally carry, does this mean the athlete would feel "supercharged"? On the other hand, what dangerous would arise? There are questions surrounding gas exchange. Would the body be able to clear the CO2? Initially, more oxygen = more performance but the body responds to stress and hypoxia.
It's an interesting idea. Thoughts, anyone?

The monopolizers of the #airspace suck all the #oxygen away & make it impossible to focus & develop strength in the ways that will destroy #solidarity quickest.

study uses ancient plant to decode #Earth's #climate history
the study focuses on #horsetails โ hollow-stemmed #plants that have thrived on Earth for more than 400 million years. The teamโs findings reveal that #water traveling through these plants undergoes such intense natural #distillation that its #oxygen #isotope ratios resemble those found in meteorites or in extraterrestrial materials.

A team of researchers at The University of New Mexico has uncovered how a peculiar, prehistoric plant might unlock new ways to reconstruct Earth's ancient climate. Led by UNM Earth and Planetary Sciences Professor Zachary Sharp, the study published in the Proceedings of the National Academy of Sciences (PNAS) titled, โExtreme triple oxygen isotope fractionation in Equisetumโ focuses on horsetails โ hollow-stemmed plants that have thrived on Earth for more than 400 million years. The teamโs findings reveal that water traveling through these plants undergoes such intense natural distillation that its oxygen isotope ratios resemble those found in meteorites or in extraterrestrial materials.
Researchers identify million-year orbital cycles as 'pacemaker' for Earth's ancient oxygenation pulses
https://phys.org/news/2025-10-million-year-orbital-pacemaker-earth.html
A research team from the Nanjing Institute of Geology and Paleontology of the Chinese Academy of Sciences (NIGPAS), along with collaborators, has found that long-term orbital variations occurring over million-year timescales may have served as the "pacemaker" for Earth's ancient oxygenation pulses. Their findings were recently published in Geophysical Research Letters.
