Researchers identify million-year orbital cycles as 'pacemaker' for Earth's ancient oxygenation pulses

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.

With all the COVID conscious people wielding #CO2 monitors, I'm wondering:

Has anyone grown enough #plants in their home to make a measurable, consistent difference in the CO2 levels indoors?

I assume plants won't do much to filter airborne pathogens, so perhaps this wouldn't be helpful for controlling infectious disease. I'm just wondering for the purpose of making closed ecological systems, and how hard it is to make a bottle garden that would make enough #oxygen to support humans.

It's widely reported that #China has been building out huge amounts of #solar photovoltaic generation, and of course that is a big contributor to slowing #ClimateChange. But what I discovered to my surprise this week is that China is also #Reforesting faster than almost anywhere else on Earth, which is an equally important contributor, and also contributes positively to the #Oxygen cycle.

Why, when humans search for alien life, do we assume they use radio?

Or that alien life would exist only on planets that we think are habitable to us? #oxygen #oceans etc

If there is alien life it could be so unrecognisable to us that we fail to see it or are unable to detect it.

Think outside the box.

So would the climate change interest you more if you knew that phytoplankton produces most of the oxygen in the atmosphere?

If they die due to warming oceans we will all suffocate.

Edit: and did you know the oxygen levels have been in steady decline for a while? Though small but still.

Плюсы, минусы и конкуренты NGFW UserGate в 2025 году

Привет, Хабр! Я Александр из OXYGEN Data Centers and Clouds . В статье ниже рассказываю про NGFW (Next-Generation Firewall) UserGate : как и почему это решение стало практически единственным на российском рынке NGFW и как живется нам с UserGate в 2025 году. Поговорим отдельно про плюсы и минусы: что удалось пофиксить, а с чем приходится мириться до сих пор. А еще расскажу про то, как обстоят дела на рынке NGFW сейчас, какие новые решения уже готовятся потеснить UserGate и за счет чего. Будет интересно!

Despite being in an #oxygen elevated micro-environment which would normally cause tissues to decay, the team discovered the initial degradation of the fish’s fatty skin also led to an #environment where #phosphate #minerals could form and rapidly replace #organic material – leading to #fossilization.

Climate change may increase the spread of neurotoxin in the oceans

Methylmercury is a highly toxic compound that accumulates in fish and seafood, posing severe health risks to humans
