"ChatGPT Psychosis": Experts Warn that People Are Losing Themselves to AI
"Of course I want to go live in the AI world, because the choice is between God on a pedestal or vanilla."
AI users are spiraling into severe mental health crises after extensive use of OpenAI's ChatGPT and other emotive, anthropomorphic chatbots — and health experts are taking notice.

By Turning Themselves to Stone, These Remarkable Fig Trees Sequester CO2 Far Longer Than Normal
The inorganic carbon in calcium carbonate typically has a much longer lifetime in the soil than organic carbon

“Noor, who made so many friends on Bluesky since she started an account there in the summer of 2023, had her account suddenly suspended on Friday. Bluesky did not send a reason for the suspension, so while she wrote an appeal, she did not know what actions she was appealing, so as of now it's still suspended. She’s been silenced, and effectively disappeared.”

A Future for Noor and Her Children
Hello! I'm Meave, a U.S. citizen sponsoring this fundraiser on behalf of my dear friend Noor Hassan and her children. Noor and her son Abdul Rahman are kind, generous people; though their original fundraiser succeeded last summer, supporting themselves and their extended family cost them everything. This fundraiser will allow them to support themselves and save up to buy passage to Egypt and pursue a better future.

Multi-Timescale Dynamics Model Bayesian Optimization for Plasma Stabilization in Tokamaks
Machine learning algorithms often struggle to control complex real-world systems. In the case of nuclear fusion, these challenges are exacerbated, as the dynamics are notoriously complex, data is poor, hardware is subject to failures, and experiments often affect dynamics beyond the experiment's duration. Existing tools like reinforcement learning, supervised learning, and Bayesian optimization address some of these challenges but fail to provide a comprehensive solution. To overcome these limi…

Unfolding the geometric structure and multiple timescales of the urea-urease pH oscillator
We study a two-variable dynamical system modeling pH oscillations in the urea-urease reaction within giant lipid vesicles -- a problem that intrinsically contains multiple, well-separated timescales. Building on an existing, deterministic formulation via ordinary differential equations, we resolve different orders of magnitude within a small parameter and analyze the system's limit cycle behavior using geometric singular perturbation theory (GSPT). By introducing two different coordinate scalin…

Today, as we approach the Declaration of Independence’s semiquincentennial,
Donald Trump and his allies claim the Revolution for themselves.
They have made fealty to the American Revolution part of their culture war against “woke” progressivism.
The Revolution has become a pawn in Trump’s politics of retribution against the country’s supposed cultural enemies.
Trump and his allies claim to be patriots
while regularly violating the principles outlined in the D…

Trump Is the Enemy of the American Revolution
He has produced a crisis much like the one the colonists faced two and a half centuries ago. Now it’s our responsibility to uphold the Founders’ legacy.

The mere fact that someone is willing to work for Trump, knowing who he is, tells you that they’re willing to debase themselves.

Why You Should Fear a MAGAfied Fed
The next Fed chair will debase himself for Trump

We’re only six months into Donald Trump’s second term,
and House Republicans are already panicking.
They’ve hitched themselves to an unpopular president.
They’ve supported deeply unpopular legislation.
And most damning?
They've proven unwilling to do anything but bow down to Trump and rubber-stamp his every whim.
 
Voters will tolerate divergence in policy.
They will excuse various styles and political temperaments.
But Americans …
