Rising surface salinity and declining sea ice - a new Southern Ocean state revealed by satellites: #salinity across the circumpolar Southern Ocean since 2015. This shift has weakened upper-ocean stratification, coinciding with a dramatic decline in Antarctic sea ice coverage. Additionally, rising salinity facilitated the reemergence of the Maud Rise polynya in the Weddell Sea, a phenomenon last observed in the mid-1970s. Crucially, we demonstrate that satellites can now monitor these changes in real time, providing essential evidence of the Southern Ocean’s potential transition toward persistently reduced sea ice coverage" -> A change in the Southern Ocean structure can have climate implications: https://www.icm.csic.es/en/news/change-southern-ocean-structure-can-have-climate-implications (the original version of this press release was full of errors as https://bsky.app/profile/mkreutzfeldt.bsky.social/post/3ltednz76r226 has documented but - as https://bsky.app/profile/micefearboggis.bsky.social/post/3ltemt57qhc2u points out - the correction was done in a most intransparent way).

It’s important to note some exceptions, not all AI pioneers fell into this trap.
Some, like Seymour Papert went to do a lot of good (creator of Logo, Mindstorms and a principal of One Laptop Per Child).

Ken Griffin has warned that Trump’s pressure on the Fed and dismissal of officials
risk eroding U.S. institutional credibility and driving up long-term borrowing costs.
He cautioned that once confidence is lost
—as seen in past crises from Nixon’s Fed battles to Liz Truss’s meltdown in the U.K.
—it is costly to rebuild.

Revolution or Hype? Seeking the Limits of Large Models in Hardware Design
Recent breakthroughs in Large Language Models (LLMs) and Large Circuit Models (LCMs) have sparked excitement across the electronic design automation (EDA) community, promising a revolution in circuit design and optimization. Yet, this excitement is met with significant skepticism: Are these AI models a genuine revolution in circuit design, or a temporary wave of inflated expectations? This paper serves as a foundational text for the corresponding ICCAD 2025 panel, bringing together perspectives…

“People who socialize more are more resistant to cognitive decline as they get older,”
Dr. Ben Rein said. And, he added, they “have generally larger brains.”
Researchers think that may be because socializing could help to protect against declines in brain volume that happen with age and isolation.
Loneliness, which is particularly common in older adults, can increase levels of the stress hormone cortisol,
and if cortisol is elevated for long periods of time it can lea…
