New paleomagnetic research suggests Earth’s solid inner core formed 550 million years ago and restored our planet’s magnetic field.

Swirling liquid iron in the Earth’s outer core, located approximately 1,800 miles beneath our feet, generates our planet’s protective magnetic field, called the magnetosphere. Although this magnetic field is invisible, it is vital for life on Earth’s surface. That’s because the magnetosphere shields the planet from solar wind—streams of radiation from the sun.

However, about 565 million years ago, the magnetic field’s strength dropped to 10 percent of its strength today. Then, mysteriously, the magnetic field bounced back, regaining its strength just before the Cambrian explosion of multicellular life on Earth.

“The final theory of nature must be octonionic,” observed Michael Atiyah, a British mathematician who united mathematics and physics during the 1960s in a way not seen since the days of Isaac Newton.

“Octonions are to physics what the Sirens were to Ulysses,” Pierre Ramond, a particle physicist and string theorist at the University of Florida, said to Natalie Walchover for Quanta.

Many physicists and mathematicians over the decades suspected that the peculiar panoply of forces and particles that comprise reality spring logically from the properties of eight-dimensional numbers called “octonions.” Proof surfaced in 1,898, writes Walchover in Quanta, that the reals, complex numbers, quaternions and octonions are the only kinds of numbers that can be added, subtracted, multiplied and divided.

NASA plans to bring 30 Martian rock samples back to Earth in 2033, the agency said Wednesday — and is sending two small helicopters to help the mission.

The Perseverance rover, which landed on Mars in February 2021, has so far collected 11 samples as part of its hunt for signatures of ancient life.

But bringing them back for detailed lab study on Earth is proving to be a highly complex task.

But Lindgren received an abrupt request to comment on the day’s big news: the new Russian space chief Yuri Borisov said the nation, which has been a steady NASA partner in space and that has ferried American astronauts up to the ISS as recently as 2020, would end their decades-long space station collaboration.

The news spread on Tuesday after the Kremlin published a transcript meant to represent a dialogue between Borisov and President Vladimir Putin, in which Borisov tells Putin that Russia will end their partnership on the ISS in 2024.
