This reveals the most important change “in the history of the planet”.

Researchers at the Massachusetts Institute of Technology (MIT) have proposed a new theory to explain how oxygen concentration might have built up in the Earth’s atmosphere, according to a press release.

Billions of years before the first humans were born, the Earth’s atmosphere lacked the oxygen we need to survive. Some microbial organisms were using photosynthesis to generate some oxygen, however, the amounts produced were not sufficient to support many lifeforms. Around 2.3 billion years ago, though, the oxygen levels began to build up in the atmosphere, but the reasons for the same and still unknown. at the Massachusetts Institute of Technology (MIT) have proposed a new theory to explain how oxygen concentration might have built up in the Earth’s atmosphere, according to a press release.

The Sun is continuing its rowdy behavior, with flares and coronal mass ejections almost every day since mid-January. That means the inevitable has happened: some of those eruptions have blasted in the general direction of Earth, which means we’re in for some solar storms.

The Space Weather Prediction Center of the US National Oceanic and Atmospheric Administration (NOAA) and the British Met Office have both issued advisories for mild and moderate geomagnetic storms over the next couple of days.

That doesn’t mean we have anything to worry about; in fact, we’ve already been hit by mild and moderate geomagnetic storms over the last couple of days, clocking in at G1 and G2 on the five-level solar storm scale.

Companies are lining up to try to hire coders who have been caught up in Russia’s invasion of Ukraine.

Some 2 million-plus Ukrainian citizens have been displaced in recent weeks, with some of them possessing in-demand technical skills.

Dozens of companies have posted over 500 job ads for tech roles on a website called Remote Ukraine that’s been set up to help firms around the world hire Ukrainians. The companies are mostly from Europe but some are also from the likes of U.S. and Canada.

Scientists say they will need to conduct studies to find out the severity of the new variant.
