In the past year and a half, we have been intensively protesting and fighting the Israeli government in an attempt to stop the war, secure the release of all hostages, and prevent the ongoing humanitarian crisis. Until now, our protests have primarily been focused internally.

Abundance by Klein and Thompson

β€œThe market cannot … distinguish between the riches that flow from burning coal and the wealth … created by bettering battery storage. … The market will not … fund the risky technologies whose payoff is social rather than economic. Government must.”

You know Trump-Vance are wrong. Another case of eating your pets nonsense.

Everybody would like the war to stop and the hostages be returned. And Hamas to leave.

These two have failed to get it done after saying they would. Repeatedly.

The image is a heatmap titled "Measles," showing measles cases across U.S. states from 1928 to 2003. States listed on the y-axis include Alaska, Arkansas, California, Connecticut, Delaware, Georgia, Iowa, Illinois, Kansas, Louisiana, Maryland, Michigan, Missouri, Montana, North Dakota, New Hampshire, New York, Oklahoma, Pennsylvania, South Carolina, Tennessee, Utah, Vermont, Wisconsin, and Wyoming. The x-axis spans years from 1928 to 2003. A vertical line marks the introduction of the measles vaccine around 1963. The color scale at the bottom ranges from blue (0 cases) to red (4,000+ cases), with shades of green, yellow, and orange indicating intermediate values (1,000, 2,000, 3,000 cases). Before 1963, many states show frequent high case numbers (yellow to red), while after 1963, cases drop significantly, with mostly blue indicating near-zero cases.

Witkoff struggled to name the five regions of Ukraine that are either annexed or partially occupied by Russian forces. He mentioned "the so-called four regions. Furthermore, his statements echo Russian propaganda. So, not great.

Understanding learning at 2 timescales (e.g., fast neuron-neuron and slower neuron-glia-neuron) seems important. We learn much over long time periods.

One learning mechanism, synaptic strength, might be possible. But ould mechanisms at 2 timescales have some value?

Right. But the hippocampus is unusual in many ways.

Modeling these types of circuits, even with a simplified basic model, seems like a real need. Something beyond the single scalar neural network.

If differentiable, it could immediately be a target to explore in applications.

Gliotransmitter - Wikipedia

Thanks. Very helpful. I see your point and am grateful for the link.

These are the doubts, in this case about gliotransmitters.

The authors make a point I find quite interesting. The energy consumption is very different in these regions. Hence the molecular signaling and neural-glial circuitry are also likely to be very different.

If so, the principle of a canonical cortical circuit is unlikely. #neuroskyence

Thanks. Should I take your comment as suggesting that current measurements are not yet convincing to the cellular signals community? I am reading reviews about the tripartite synapse (e.g., A conceptual framework for astrocyte function, Nat. Neuro) and many related. Are there doubts?

In sensorimotor neuroscience, it is a given that one needs to know the input and/or output to understand the neural signals.

A good principle, but harder to operationalize in cognitive and affective neuroscience. Surely worth the effort, IMHO.

A question for cellular neuroscientists.

In my teaching, I include the tripartite synapse. Has research evolved to the point where I should lead with the concept?

And what about transmission from the Nodes to glia in the white matter? Fully established or speculative? #neuroskyence

Another tool for noise correction has been developed by Kendrick Kay. Largely for task-based fMRI. Originally, GLMDenoise and now extended to GLMSingle. Kendrick used to maintain a table comparing different methods, but I haven't seen that lately.

A Decade of Cuts in a Matter of Days The Trump administration’s rapid terminations of NIH grants is its most aggressive attempt yet to control American science.

Excellent coverage of NIH activities. The reporting reveals no principles of the cuts, just buzzword thinking and directed animus.

Republicans have hated universities for years. Anti-war protests gave them a reason to punish them. The White House is casting elite universities as hotbeds of hate as the diploma divide reaches an all-time high.

The administration is stopping federal funding of basic research in health, climate, and science. Why? Stopping antisemitism is not the goal. Cutting waste is not the goal. It is a culture war. Vance in a 2021 speech, "The Universities are the Enemy".

β€œScience, to succeed, needs free speech,” Bhattacharya told the committee during the hearing (the Atlantic)." But the article shows his papers and the GB Declaration are widely known, just not widely accepted.

So, he means: 'Agree with me, or you're silencing science.' Worrisome.
