12 dead at a mass shooting at a Hanukkah celebration at Bondi Beach.💔 A 43-year-old father of two, Ahmed al Ahmed, snuck up & tackled a gunman to disarm him. Ahmed was shot twice. Both Jewish & Muslim faiths teach that “to save one life is to save all humanity.” Let us hold fast to our humanity.❤️

Are you interesting in cities and how to make them better for everyone? Bluesky has, in my observation, the biggest and best community of urbanists and city-builders on social media, and STARTER PACKS were a KEY to creating that! I have a bunch of them. This was my first! go.bsky.app/G7isZfk

Finally finished this last week and highly recommend! Such a carefully crafted timeline of the history of life in the air and the science that describes it. Loved the chapters on the Mills' and Lindberghs' contributions many decades ago. The fight for clean air is nothing new! @carlzimmer.com

Just learned that @sfdirewolf.bsky.social passed on If you didn't know much about Alice Wong, they were a disability rights activist. A couple years ago, read their 'Disability Visibility' book of essays— definitely worth reading disabilityvisibilityproject.com/book

Our beloved Alice Wong has joined the ancestors. It was one of the great honors of my life to call Alice my friend, co-author & co-conspirator. She was a true genius, a force of nature the likes of which the world has never seen before. I love you, Alice, and am equal parts grateful and devastated

I don’t want to formulate words yet, but my friend Alice Wong, @sfdirewolf.bsky.social of the Disability Visibility Project, has passed. Here are the words she left behind: www.instagram.com/p/DREMDNBjnq...

Alice was a mentor, a friend and one of the people who I credit with helping me find my voice. She gave me the strength to embrace my disabilities and use my skills as a writer to help others. My life is forever changed because of her. I will have more to say once I’ve processed 💔

Really great results in this early phase 1 trial of a nasal vaccine (mucosal vaccine) for avian flu- great to see evidence of strong immune memory and robust antibody response

Word of the Day is ‘catchfart’ (17th century): an obsequious individual who sucks up to the boss and always follows the political wind.

15 years ago, I said every social media founder should be forced to use and live with the default settings of their platforms. Now I would say that the AI founders should have their tools pointed at their families for a year before they can deploy them elsewhere.

The US is the world's largest oil and gas producer. Yet, "China is now making more money from exporting green technology than America makes from exporting fossil fuels."

1. This is a thread on freedom, and how easy it is to lose. Over the past 2,000 years in Europe, there have been few periods and places of freedom. For much of the time we lived under highly oppressive tyrannies of various kinds, whether small or grand, local or imperial, secular or religious.🧵

‘Study after study shows that students want to develop these critical thinking skills, are not lazy, and large numbers of them would be in favor of banning ChatGPT and similar tools in universities’, says @olivia.science www.ru.nl/en/research/...

This man is clearly deranged

A new study concludes that the construction industry alone will blow through the carbon budget ceilings even if every other source of emissions were reduced to zero. " If current trends continue, the sector can exceed the 2°C per annum carbon budget earliest by 2040.”

'COVID-19 still causing a lot of serious illness. This study showed that 2024-2025 COVID-19 vaccines were effective, especially against severe outcomes, although their effectiveness waned over time. Thus, it is beneficial to have an annual COVID-19 vaccination.' www.news-medical.net/news/2025102...

Hey nerds! I’m in Mt Kisco today giving a talk on the public health and climate harms of natural gas and got a tour inside the guts of the village’s public, fast, EV charging system which includes an array of batteries to store rooftop solar collected from the top of the courthouse and cop shop. 1/3

This @royalsociety.org report has not received nearly the attention it deserves. Key finding: "most current approaches to economic assessments of impacts of #climate change do not reflect the severity of consequences that are suggested by the latest physical climate science & evidence on impacts" 😬

NHS COVID-19 vaccine policy: 🤦'If eligible, COVID-19 vaccination will give you protection from serious COVID illness over winter'. ✅ 75 and over ✅ Immunosuppressed ❌ Everyone else - even if your doctor recommends it. 🤷That’s not public health. 🤦That’s exclusion. 💉 ukhsa.blog.gov.uk/2025/06/26/w...
