What should Europe do when demand for #ERC funding keeps rising?
Restrict access or invest in excellence?

Please read our open letter calling for reconsideration of the ERC 2027 resubmission restrictions & for constructive alternatives that preserve openness

When you realize Danio (rerio) & Oryzias (latipes) are both derived from "rice" in different languages 🤯

Danio derived from Bengali word "Dhani" or "of the rice field"
Oryzias derived from Greek word "Oryza" or "rice"

The Lesson Every Democrat Should Learn From Peter Magyar's Victory In Hungary The cost of living crisis needs a villain.

Peter Magyar's victory in Hungary was fueled by a potent message tying the affordability crisis to the corruption of wealthy elites. With Trump presiding over unprecedented corruption and with prices skyrocketing, Democrats have the opportunity to replicate Magyar's success in November and beyond.

Mayor Mamdani and a group of children hold hands while running through red tape in a hallway.

Mayor Mamdani and a group of children hold hands while running through red tape in a hallway.

For too long, bureaucracy kept 7 child care centers across our city empty — spaces that should have been alive with laughter instead collected dust.

We've run through that red tape. This fall, all 7 will open their doors, bringing an additional 240 free 3-K seats & real relief to working families.

Channeling grief into discipline:

When I was at the Washington Post, I had a newsletter that would come out every Friday.

But in the last few years, I've felt intellectually and creatively stifled. Since my illegal firing and my father's death, I'm rediscovering what I've lost. (1/2)

An orange white and black calico cat named Rainbow greeting CC, who is in that late kitten stage, and is a tabby calico, no orange.  They sit on a conference table, and Rainbow looks like she's about to either groom or bite CC.

An orange white and black calico cat named Rainbow greeting CC, who is in that late kitten stage, and is a tabby calico, no orange. They sit on a conference table, and Rainbow looks like she's about to either groom or bite CC.

The first cat to be cloned was a calico female named Rainbow (left).

The clone, produced at Texas A&M University in 2001 was named "CC" for Carbon Copy or CopyCat (right).

Notice something odd about the "identical copy"?
Not very identical is she?
But they *are confirmed* genetically identical.

Right. I've often said that the solution is sewer socialism. We didn't stop cholera by shaming people who didn't purify their own water, we built infrastructure that eventually ensured clean water was the norm. We can do that with air quality.

Pointed essay about what Americans faced during wars, the great depression, and the civil rights movement.

Now what is needed is to stay engaged, pay attention, and help where you can.

America is worth it.

From viewers to voters: Tracing Fox News’ impact on American democracy This paper provides a comprehensive assessment of the effect of Fox News Channel (FNC) on the mass public’s political preferences and voting behavior …

And this corruption of the free and fair marketplace of ideas did not just do a lot to bring us Trump (via Fox-see below @chriswarshaw.bsky.social , Twitter, pink slime news, Newsmax, etc), it’s directly harmed US science.

The COVID denier, lab origin, Fauci/NIH-bad and antivax stuff uses this

So we all have to care - voters, those who want to live in a free society, science people, and anyone who gets diseases from viruses to cancer. The l info environment is broken in large part due to this strategy and we need to see it and fix it.

“A small number of extreme users constantly post fringe opinions, which creates the illusion that these views are far more widely held than they really are.”

This is a critical concept.

The Democrats make perfect sense when you stop seeing them as a political party, and view them instead as a business venture that provides political entertainment, but with a clear profit motive

What if you got to work with some of your best friends on a science project? I can't publish how fun this was, but I can show you the data (🧵)! Last week, we posted our second neutrophil swarming paper to bioRxiv and I wanted to post my favorite videos here~

Virginia: Vote YES Tomorrow Virginia's Redistricting Referendum and Why I'm Passionately In Support

Trump ordered Texas to redraw its maps mid-cycle — not because the census required it, but because they know they can't win a fair fight in 2026.

Virginia votes tomorrow. Matching the GOP isn't enough —

Effective 2025 federal tax rates paid by these corporations:

Alphabet: 8.01%
AT&T: 4.6%
Meta: 3.57%
General Motors: 3.09%
Amazon: 1.37%
Exxon Mobil: 1.31%
Disney: -1.57%
CVS Health: -3.88%

Income tax rate paid by the typical American: 14.5%

This is what a rigged system looks like.

Just sobbed hardest I have since my mom died in 2020.

She missed these trials by a few months.

One of most ruthless cancers. Hard to fathom that maybe she'd still be here.

I feel such a hole inside.

In case you're wondering if we should fund mRNA research instead of another stupid war ... yes.

Figure 2. FORCE1s reports in vivo neuronal activity with high fidelity under resonance
scanning 2-photon microscopy
(A-I) 2P-guided whole-cell patching and resonant-scan imaging in anesthetized mice.
(A) Experimental schematic.
(B) 2P images of a representative FORCE1s-Kv-expressing neuron are shown at high resolution (i) and the size and
resolution used during voltage imaging (ii). The patching pipette is outlined.
(C) Simultaneous electrophysiological recording (top, 10 kHz) and FORCE1s-Kv fluorescence imaging (bottom, 440
Hz). The fluorescence trace was low-pass filtered at 150 Hz to enhance the visualization of the spikes. Dashed
boxes: epochs shown in panels D-E. Vertical lines: detected spikes. Gray triangle (left, and in panels D-E): -70 mV.
(D-E) Zoomed-in subthreshold (D) and bursting (E) epochs. Panel D’s optical trace was low-pass filtered at 50 Hz to
enhance the visualization of subthreshold fluctuations.

I'm not joking when I say mRNA technology is more important than "AI" and it's a tragedy we're throwing billions into one while our government is aggressively defunding the other.
