"Whale breath collected by drones is giving clues. [...] Scientists flew drones [...] through the [...] "blows", made when the giants come up to breathe through their blowholes.

They detected a highly infectious virus linked to mass strandings of whales and dolphins worldwide."

When you block a number on one Apple device, it blocks it on all Apple devices and apps. This includes the Phone app, the Messages app, the Facetime app, and yes, even the Mail app.

The Mail app was a surprise to me, since I didn't think that "Block a number" would include blocking any email addresses linked to that phone number in your Contacts app. But it does. (and annoyingly it sends those emails to Trash instead of to Spam)

Live, replicating SARS-CoV-2 lingers in hamster brains 80 days post-infection—triggering depression-like behavior, memory loss, and anxiety. This isn’t just collateral damage. The brain is infected. https://www.nature.com/articles/s41467-025-62048-7
Hamsters with long COVID present distinct transcriptomic profiles associated with neurodegenerative processes in brainstem - Nature Communications

SARS-CoV-2 persists in the brainstem long after the initial infection has passed. Infected animals exhibit symptoms of anxiety, depression, and memory impairment as well as changes in the brain that can be related to neurodegenerative processes.

A major new review from Yale (Moen, Baker, Iwasaki, 2025) offers the most comprehensive picture yet of what SARS-CoV-2 does to the nervous system.

The conclusion is stark:
Long COVID is a chronic neuroimmune disorder affecting brain, spinal cord, and peripheral nerves.

Sadly, I think I've seen that 2024 age distribution before. I lived in New York in the 1980s.

My information may be very outdated, but there's been a free open-source version of Matlab available for years:

GNU Octave

GNU Octave is a programming language for scientific computing.

@katchwreck

You're not being pedantic at all. I just didn't look at it closely enough to realize that the underlying potential energy function did not exactly correspond. That's a big negative, in my opinion. But still an impressive experimental "hack".

Thanks for setting me straight!

@MarthaCrimson

Every time I am curious about something, and someone warns me to "remember that curiosity killed the cat", I want to respond with "oh yeah? why don't you remind me *exactly* how that old story went!"
