Allen acknowledged that this hantavirus outbreak is not likely to spark a pandemic because it’s less contagious than influenza, measles, and SARS-CoV-2. But, he added, “Public-health officials have to be more honest and more humble about how this virus actually spreads. An essential lesson from COVID is that officials should be candid about communicating that we are often learning in real time, and we should shy away from making bold pronouncements that may prove dangerously misleading weeks or months later.” hsph.harvard.edu/news/how-ha…

Honestly, not trying to stir things up or be a contrarian or anything. I do forensic investigations of sick buildings frequently and I approached this w same curiosity - I’m trying to be objective about what’s known and not known, and wanting to understand how it’s spread (so we know how to protect people!) and after reading the parroting about “prolonged close contact”, I went and read the best outbreak investigation we have to date on h2h hantavirus spread and assumed I’d find supporting evidence. Instead I learned that nowhere in that NEJM does it show prolonged close contact is required. In fact, many examples of *the opposite* It’s not esoteric or fear-mongering; it’s important we get this right: -to keep people safe from this, including those who were on the ship, contacts and their families, and the treating medical teams -don’t miss anyone w contact tracing (are we only looking for people w “prolonged close contact”??) -learn as much as we can about Andes strain transmission (there’s very little published on outbreak dynamics)

France passed a law requiring solar panels on every parking lot with more than 80 spaces. Parking lots over a certain size have three to five years to cover at least half their surface area with solar canopies or face fines. The projected output: up to 11 gigawatts of capacity, the equivalent of 10 nuclear reactors. The panels shade the cars. They can charge EVs directly underneath them. They generate electricity for the grid. The parking lot goes from dead infrastructure to power plant without using a single additional acre of land. France plans to increase solar tenfold and double wind capacity by 2033. The US has approximately 800 million parking spaces. Eight hundred million. Most of them are uncovered asphalt sitting in direct sunlight. Why aren't we doing this?

The holidays are meant for connection, not illness. COVID, flu, RSV, and measles can spread easily during gatherings, often from people who don’t yet feel sick. COVID, in particular, remains airborne, persistent, and capable of causing long-term health impacts — even after mild or asymptomatic infections. A safer holiday season doesn’t require perfection. It requires awareness, shared responsibility, and practical steps that reduce risk — like staying home when sick, improving indoor air, masking when needed, and testing around gatherings. Care is not an overreaction. It’s how we protect one another.

COVID, flu, and RSV spread most easily this time of year, especially when we’re gathering indoors. Simple steps like improving indoor air quality, wearing a high-quality mask when needed, testing before gatherings, and staying home when sick can meaningfully reduce risk without taking away from joy or togetherness. No single action does it all. But layering protections makes gatherings safer and more inclusive. Protecting each other isn’t about giving up celebrations. It’s about making sure more people can enjoy them, both during the holidays and after.

Today I was asked by a Russian journalist (Zarina) from RIA News Sport whether I would participate (if invited) in the match between former @NHL and Russian KHL stars, as Trump and Putin reportedly recently agreed. This is my answer 🧵

This chart has been making the rounds on social media. It suggests that renewables increase electricity prices. But it's misleading and pretty typical of the author, whose nonprofit has received ~$1m from ExxonMobil. Here's what's wrong with it 🧵

The Raccoons is one of the most beloved shows in Canadian history. From the specials that aired in the early-1980s, to the show that ran from 1985 to 1992, to the theme song itself, it is a shot of nostalgia for Canadians. This is the story of that show. 🧵 1/14

This iconic Ben Stein scene might be almost 40 years old, but it feels like essential viewing now that Trump is tariffing the world.

The UN Charter was drafted in 1945 by people who had learned the lessons that the aggression, isolationism and tariff barriers of the 20’s and 30’s had led the world into a conflagration. Article One makes it clear: threats of annexation are illegal. So are unilateral tariffs in breach of a trade agreement.

It's extremely important to keep in mind how congestion surges once roads approach capacity. Good example from NYC congestion pricing, 8% fewer cars translates to 20-40% faster commutes

On this day in 1967, Songs of Leonard Cohen released. The debut album of a Canadian icon, it helped Cohen transition from poetry into a musical career. Today, it is considered to be one of the best albums ever made. Let's learn more :) 🧵1/15

2024 will go down as the first full year when wind and solar generated more electricity than coal. Our air and water is cleaner, our electricity is cheaper, and our world is better as a result.

Nuclear Power Update: Fission vs Fusion Fusion now generates 3/4 as much electricity as fission and is set to overtake fission in 2026. Note: fusion data does not include generation from unregistered SMRs (small modular receivers). These may account for around 10% of total power generation in places like Pakistan.
