So this will be the last thing by The Narwhal I ever read, at least as long as they persist in theft and climate death.

I'm so proud of my kid for recognizing the toxicity and danger of this, and coming to me about it. We've talked about social media and radicalization, about how it almost always starts as jokes so they can say you're overreacting, it's not serious... and then it gets darker.

Talk to your kids.

When someone says β€žScientists do not want you to knowβ€œ you can dismiss everything from there on. Scientists want you to know. They are desperate that you know. They can’t shut up about what they found out and want you to know.

Know what water fluoridation is correlated with?

Fewer cavities.

Lower heath costs.

Increased equity as a universal heath benefit.

Likely lower rates of heart disease by reducing rates of Streptococcus mutans in the blood stream.

Which again, lowers heath costs and increases equity.

I’ve unmasked a white nationalist fight club in my city: Montreal.

After weeks of work (with help!), I can reveal an Olympian as a member of the Frontenac Active Club β€” one who, unbeknownst to the owners, brought them to a local gym for training and propaganda photos.

Here’s my investigation:

Donate to Keep Diane's Sanctuary Dream Alive, organized by Beth Hyman Update: An extaordinary amount has been happening behind the scenes here at Squirrelwood… Beth Hyman needs your support for Keep Diane's Sanctuary Dream Alive

I've posted the heartbreaking update to the GoFundMe. The town is not agreeing to the HVSPCA using this property as a shelter. This is devastating. I'm at a loss. I budgeted to March 1st transfer. You've always been there for me and D. gofund.me/966bfb70e

The cross-section of the abalone shell showing a layered microstructure composed of aragonite platelets, separated by a thin layer of conchiolin. The thickness of each nacreous layer is about 0.5 ΞΌm.

Each "aragonite platelet" in the image is 0.5 microns thick, made of 5% protein and 95% calcium carbonate.

Here's a transverse/cross-section view, showing each tile is "stacked" on millions of others.

Imagine the biological processes involved in laying these down to form "Gastropod Armor +5".

An abalone shell made up of 0.5 Β΅m thick tiles of calcium carbonate, or chalk, cemented together by a protein coating. The whole structure is 3,000 times more resistant to fracturing than a crystal of calcium carbonate alone. This property comes from the positive charge of the protein coating that binds to the negative charge of the hexagonal calcium carbonate tiles. This binding is weak enough that the layers can slide slightly apart to absorb the energy of a blow. Material scientists interested in biomimicry are seeking to replicate this structure to create tougher materials.

What looks like a topological map for a TTRPG is in fact an SEM image of an abalone shell.

While shells are primarily made of calcium carbonate, there's a protein matrix that makes shell '3,000 times more resistant to fracturing than a crystal of calcium carbonate alone.'

Almost like shutting down safe consumption sites and funneling money away from harm reduction and into abstinence grifting makes things less safe and increases harms. This is consistent with decades of data and was completely predictable.

the best advice i can give new PI's is not to put all your eggs in one basket (the crowd nods) for example, let's say you had one $12.5m grant. sounds pretty good right? but what if you lose that grant? (the crowd nods more) instead, try having two $12.5m grants (my handler moves towards the stage)

Inside a Surrey β€˜local news’ site run by AI Surrey Speak published fake news about a politician and an AI-generated picture of a real murder victim

Last month Surrey news site published a scoop about a Vancouver politician's shock resignation.

Except that never happened.

Our investigation found the website, Surrey Speak, is powered completely by AI. And it has links to a tech company backed by SFU #vanpoli
