A recent study published in the Proceedings of the National Academy of Sciences examines how marine phytoplankton throughout the North Atlantic Ocean has maintained its stability and numbers based on ice cores dating as far back as 800 years, which contradicts a 2019 study that concluded marine phytoplankton was on the decline by approximately 10 percent. The reason ice cores were examined was due to the methanesulfonic acid (MSA) deposits that fall from the sky and are the airborne products of phytoplankton, with the MSA initially starting off as dimethyl sulfide that is a byproduct of phytoplankton. This study was also presented at the AGU Fall Meeting in December 2022.

“Greenland ice cores show a decline in MSA concentrations over the industrial era, which was concluded to be a sign of declining primary productivity in the North Atlantic,” said Ursula Jongebloed, who is a PhD student in atmospheric sciences at the University of Washington (UW) and lead author of the study. “But our study of sulfate in a Greenland ice core shows that MSA alone can’t tell us the whole story when it comes to primary productivity.”

The Polestar 4 uses a camera setup instead of a rear window and rearview mirror, and it offers benefits beyond visibility.

The new Polestar 4 is the Swedish EV brand’s first crossover coupe, slotting between the compact and midsize segment.

The surprising aurora-like display was seen at 40,000 km above a rather dark and cold area of the Sun known as a sunspot.

A recent study found that LLMs are incredibly good steganographers, able to obscure their own thought processes through “encoded reasoning.”

Google pays Apple 36% of its search advertising revenue from Safari under the terms of the two companies’ search default agreement, an Alphabet witness said.

Tesla has signed a deal with the EG Group, a massive gas station and convenience store operator, to sell its Supercharger hardware to be deployed as an EG-branded product.

It’s the second of such deals that Tesla has made in just a few weeks.

Last month, Tesla surprised many when it announced it reached a deal with BP to sell them $100 million worth of Supercharger hardware to be deployed at BP gas stations across the US under the BP brand.
