In honor of Mr. Rogers’ birthday, here’s your regularly scheduled reminder that the quote of his you keep sharing, that in times of crisis we should look for the helpers, was for his audience of children. We’re adults now. We’re supposed to *be* the helpers.

The world is far off track for “30×30,” but 2025 brought progress. Here are some wins from this year.

Can’t believe the whole country has to suffer through the return of Dickensian childhood diseases because the worst, most ignorant attention-demanders decided other people’s expertise makes them feel bad

Oh my god. Having a team in an epic World Series is probably the worst thing that's ever happened to me

Hurricane Melissa which is en route to decimate Haiti and Jamaica rapidly intensified to category 4 storm. Rapid intensification is a hallmark of climate change, but that category is only a measure of its wind speed. It is also expected to bring up to 40 inches of rain

Big thanks to the folks at the CBC's Quirks and Quarks for having me on as a guest to talk about Rise of the Zombie Bugs! It was great fun chatting with host Bob McDonald about my favorite zombifiers and what we can learn from them about parasitism, neuroscience and evolution 🧪

Long Covid Is Real — And It’s Changing an Entire Generation Hundreds of thousands of kids in America are struggling with an illness that many doctors and schools refuse to recognize.e Feature: www.rollingstone.com/culture/cult...

This is a REALLY good video that gets into the *specifics* of how AI is degrading our information environment and putting truth further out of reach for the average person / the population as a whole

I am not a political pawn. I am a living, breathing human being who has dedicated her life to a scientific problem that I believe matters for human health. The article below tells our story; I hope you will read it and share it www.nytimes.com/2025/09/14/m...

This is one of my favourite themed episodes that we do, where we get to really lean into the stories of scientists as explorers and adventurers. Season 50 of Quirks & Quarks kicks off today! www.cbc.ca/radio/quirks...

NEW: in recent weeks, right wing media and influencers have seized on new research suggesting a connection between Tylenol use during pregnancy and autism Ariana Cha, @laurenweberhp.bsky.social and I broke down the science and what MAHA influencers are claiming wapo.st/4gdFIPt

Florida Decided There Were Too Many Children

"Sweeteners can harm cognitive health equivalent to 1.6 years of ageing, study finds" Or does it? Let's take a look at this "study"... www.theguardian.com/food/2025/se...

I get annoyed at the narrative that all the awareness and work on climate change hasn't done anything. Yes, global CO₂ emissions indeed continue to climb, but we don't know the counterfactual. When I was in grad school, we were on track for 5°C of warming. Now it's below 3°C. That's progress.

can ppl stop screaming about WW3 the thing about world wars is to start one you need countries to go to war that have friends who also want to go to war for their buddy, not 2 countries led by guys whose own wives refuse to talk to them

Good review of evidence.👇 The internet is full of misinformation. That's by design, experts say www.cbc.ca/radio/quirks... Me: "Our information environment is completely manipulated, and often people don't realize the degree to which that is the case." We're living through a knowledge crisis!

Woo hoo! I'm super chuffed to be nominated for our Overheated special, especially in a category stacked with some really heavy hitters. Congrats to everyone!

CBC science show Quirks and Quarks just had another great episode talking about the long term damage caused by each COVID infection. If you're starting to wonder why so many hard-core scientists are so contemptuous of our public health institutions, listen to this. www.cbc.ca/radio/quirks...

It is genuinely your moral duty, if you’re in the sciences, to violate the terms of your contact and take as much of the research home with you as you can. Today, tomorrow, every day your lab’s still open.

“I love what I do. That is what I want to pass on to my children. We must protect the ocean so that they can have the same healthy lives as us.” The South African fishers fighting fossil fuels - by @barrychristianson.com on @dialogueearth.bsky.social dialogue.earth/en/ocean/the...

Stop dismissing Trump and his team’s *repeatedly stated plan to annex Canada* by, at the very least, bringing us to our financial knees, as a “negotiating tactic.” Sending people their relative’s fingers in the mail is also a “negotiating tactic. One practiced by criminals, not good neighbours.

Fun fact: five years later, we still have our show lineup on the whiteboard of our last show before COVID lockdowns hit. It never felt right to erase it, so we just left it.

If you want to know how concerned to be about climate change, talk to a climate scientist. Very. If you want to know how concerned to be about the rise of fascism, talk to a historian. The ones I’ve spoken to are as concerned about our time as any other time in the last 100 years.

The recent AI explosion is transforming how we create, how we write, and even how we do science. For this week's show I decided to dive into how AI is seeping into every aspect of the scientific method, and what that means for the scientists of the future. www.cbc.ca/listen/live-...

We just published an especially relevant warning from Craig McLean, the acting chief scientist and head of NOAA Research during "Sharpiegate." He defended scientific integrity—and was removed as chief scientist. Scientists can't be silent now either, he says. www.motherjones.com/politics/202...

Mind-boggling wreckage. Among the lifesaving programs now disrupted by Elon’s attack on @USAID: phase 1 trials for a possible HIV vaccine.

Everyone in LA is sharing this story on insta, and I just want to make sure non-Angelenos know about this bear that crawled under a house during the fires. He had to be lured out with rotisserie chickens. Read it. You deserve a little treat.

Journalist friends, I do not work for NOAA, but as a DC-based ocean conservation scientist and policy specialist, I know a great deal about the important work they do. I’m happy to chat about that if useful. DMs open or whysharksmatter at gmail.

NASA did a feature on me last year. It was up this weekend but now when you click on the link you get a 404 message.

Around 10 years ago I almost died because a road not built with climate change in mind was so wrecked it damaged the bus I was on. I knew that I would eventually write a story about how climate change is wrecking roads, and endangering lives. This is me trying to explain that. Gift lift.

Looking at photos of the ‘Alalā (or Hawaiian crow) and I can absolutely see how these guys are considered important spiritual guardians who guide souls to the afterlife.

Just making sure that everyone is aware of this crab that NOAA scientists found

Agree with @katharinehayhoe.com. Much too often when people are calling for ‘neutrality’, it is a sign of status quo bias. But status quo is not neutral. It is just what we have gotten used to. Example: Cars fill our cities. Changing that seems not to be neutral. But is maintaining it neutral?

This week, we spoke with the indomitable @katharinehayhoe.com about how climate science got to be so polarized and why she thinks scientists should stop trying to pretend to be neutral when it's our planet at risk. www.cbc.ca/radio/quirks...

More Facebook wasteland: I've seen a few of these sponsored ads pass by. Lamenting the big guys closing down a mom and pop. Last time it was two ladies who also just became grandmas. There is no bricks & mortar. There is no address. It's all a scam. Comments hidden so no community push back.

"Yes, it's true that you can't solve the climate crisis alone, but it's even more true that we can't solve it without you. It's a team sport." This piece by @maryannaise.bsky.social is so relevant today! www.wired.com/story/what-y...

Occasional reminder that there’s no, “it’s too late, its over” for anthropogenic climate change. Every molecule of CO2 that doesn’t go into the atmosphere makes a difference. Preventing 0.1 degree of warming makes a difference. Every bit of climate resilience we build together makes a difference.

My jaw dropped when reading this stat: the emissions from just 88 corporations are at least partly responsible for 37% of the area burned by wildfires across North America in the past 35 years. The paper and sources are linked below.

Researchers just wanted to eavesdrop on fish in the deep sea, but they ended up getting so much more. My final documentary of 2024 is about silly seals sabotaging serious science: www.cbc.ca/listen/live-...

I'm feeling some kind of way about turning 40 next week so I decided to dive deep into the science of human longevity. Is it possible for us to live to 150? Turns out, not yet - but that shouldn't be the goal anyway. www.cbc.ca/listen/live-...
