Down at the Grebe Factory interviewing the new apprentices for the Western Grebe Taxi Service, I'll thread in stills/video as I process them As a primer, here's THE BEST WESTERN GREBE MATING RITUAL FOOTAGE OF MY LIFE Warning on this thread: too cute for doom Skip to :41 for just rushing. 🪶 🐣

It’s truly astonishing to see how comprehensively the US government is tearing down every part of the system that has made it up until now a world-leading power in science, research, and technological development. The entire world will suffer from this wanton destruction.

White House proposes new rules giving political appointees final approval of research grants These proposed Office of Management and Budget regulations would render the federal research grant review process opaque www.scientificamerican.com/article/whit...

We value dogs more than moms. I realized today that if my dog had puppies, it would be considered cruel to separate them any earlier than 8-10 weeks postpartum. But so many moms in America are expected to leave baby and get back to work in just 4 weeks!!

Bluesky has genuinely revived my love for science communication online. After watching the same posts go nowhere on Twitter, seeing them resonate here has been such a good reminder of why I do this. Thanks for being here 🖤

Incredibly proud of my former student, Rohan Gowda Thanh Quang. His new paper in 𝘌𝘯𝘷𝘪𝘳𝘰𝘯𝘮𝘦𝘯𝘵𝘢𝘭 𝘙𝘦𝘴𝘦𝘢𝘳𝘤𝘩: 𝘌𝘯𝘦𝘳𝘨𝘺 analyzed $128B in US climate investments & finds that 𝘃𝗲𝗻𝘁𝘂𝗿𝗲 𝗰𝗮𝗽𝗶𝘁𝗮𝗹 𝗶𝘀 𝘀𝘆𝘀𝘁𝗲𝗺𝗮𝘁𝗶𝗰𝗮𝗹𝗹𝘆 𝗺𝗶𝘀𝘀𝗶𝗻𝗴 𝘁𝗵𝗲 𝗵𝗶𝗴𝗵𝗲𝘀𝘁-𝗶𝗺𝗽𝗮𝗰𝘁 𝗰𝗹𝗶𝗺𝗮𝘁𝗲 𝘀𝗼𝗹𝘂𝘁𝗶𝗼𝗻𝘀 - especially nature-based solutions. Results in 🧵: 1/9

I wonder if this marks a broader shift from participation in content creation to passive content consumption, or if it simply reflects how online social behavior has moved off of legacy social media platforms (“public square”) into group chats (“private salons”)

Is social media dying? How much has Twitter changed as it became X? Which party now dominates the conversation? Using nationally representative ANES data from 2020 & 2024, I map how the U.S. social media landscape has transformed. Here are the key take-aways 🧵 arxiv.org/abs/2510.25417

Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.

#DataScience & #EnvironmentDS education community: curious about your ideas on a project-based learning module focused on addressing the climate/biodiversity/poverty triple challenge. One thought: have students read papers such as this recent publication by @jasonhickel.bsky.social & replicate it.

Providing decent living standards for 8.5 billion people requires only 30% of current global energy and material use. www.sciencedirect.com/science/arti...

if you are overwhelmed, I highly recommend: -making a list of things you don't care about being out of the loop -cutting down on alcohol -cleaning, organizing and decluttering your home instead of doomscrolling -making plans with friends -weekly therapy -charging your phone away from your bed

I don’t disagree, but I wonder how we can preserve loose ties (joy of learning, social movement formation) as platforms continue to enshittify. Anecdotally, parts of science Twitter shifted to gated Slack/Discord groups after Musk took over. But they lost outside attention and idea sharing.

I think AI is going to eventually tank in the longterm, but... the only real way to combat this is single-interest communities. Forums, user comms, etc, with a barrier to entry. They become trustable knowledgebases. It's really the only way forward is to return to what worked best the first time

a text post from Michael Tonelli: "It's really unbelievable the niche parts of the internet that Al is ruining. My wife looks up crochet patterns online. It's now overrun by Al made up patterns that make no logical sense. My wife said if you tried to crochet the pattern that Al hallucinated, it wouldn't even be possible.
And it's like, why? Why is someone ruining free crochet patterns? How were they even aware of that corner of the internet? Is there a plan to make the internet so unusable that people abandon it so we don't have access to information anymore?"
