With warmer weather on the way and March Break approaching, respiratory virus activity in the community remains steady. Influenza and COVID-19 levels are similar to what we saw last week.

Working on a q&a lecture for a class today: The story of robots is always a story about slavery. The story of LLMs labeled as AI is a story about class, and which humans pay the cost, including the physical toll on their bodies/minds, and the lack of water and electricity, so data centers can exist.

This image shows gauges with the Feb 28 - Mar 13, 2026 COVID Forecast scores for Canada, the provinces, and territories. From left to right:

Canada: HIGH - 6.7
Alberta: HIGH - 6.5
British Columbia: MODERATE - 4.4
Manitoba: VERY HIGH - 10.0
New Brunswick: HIGH - 7.1
Newfoundland & Labrador: MODERATE - 4.7
North: HIGH - 6.7
Nova Scotia: HIGH - 6.0
Ontario: HIGH - 7.7
Prince Edward Island: MODERATE - 4.9
Quebec: HIGH - 6.6
Saskatchewan: HIGH - 8.1

A text box reads: 'The COVID Forecast is calculated from 3 equally weighted categories: 1) Current infections and spread; 2) Healthcare system impact; 3) Mortality. Within each category there is one sub-category for trends over the most recent week (Trends) and one sub-category for current parameter values relative to a specified baseline (Current values). Trends and current values are weighted equally when determining the final score for a category. All Forecast input data and sources are available here (https://datastudio.google.com/embed/u/0/reporting/42b886cf-d661-488e-b7d8-5c5836b55ab6/page/p_2yqs028mwc). Past Forecast scores are available in the table below. Forecast scores are grouped into 4 ranges: MODERATE (1 to <5, white), HIGH (6 to <10, yellow), VERY HIGH (10 to <15, orange), SEVERE (>15 red).'

People refuse to acknowledge how an LLM actually works, and insist on assigning meaning and understanding to its output. There is no meaning, and the system understands neither the user’s question nor its own “response.”

Did you know that the bees that need saving are NOT honeybees?

Honeybees are the dairy cows of bees. People brought them over from Europe to make us honey.

The problem with honeybees, esp in resource-limited ecosystems (like hey! cities!) is that they compete with our native bees for food.

winter sun shines high above a circular still water tank at a sewage treatment plant. The sky is blue with puffy clouds and brick buildings are on the distant horizon. the sky and sun reflect off the water in the tank. the foreground seemingly connects to the distant buildings as a catwalk on the left extends from out-of-frame bottom towards the horizon.

sewage is water with life experience.

it reflects the choices we make and carries with it the residue of our yesterdays and years.

it can unsettle us—until we realize it was once a part of us. our pasts make us who we are today.

and can inspire us to be better tomorrow.

A study I led came out in Nature Cities yesterday!

We used radar to study the role that urban landscapes play in migratory bird stopover. Spoiler: birds use cities a lot, and the patterns of their use reflect social processes and the inequities embedded in them.

Youth Anti-Trans Legal Risk Assessment Map of the United States. Florida, Kansas, and Texas are marked "Do Not Travel" with dark crosshatched shading. The majority of states are dark red for "Worst Active Anti-trans Laws." Montana, Nebraska, Alaska, and several others are orange for "High Risk Within 2 Years." States including California, Colorado, New York, and other previously protective states are now light peach for "Moderate Risk Within 2 Years," reflecting the update that no state is considered low risk for transgender youth. No states appear in low-risk or protective categories.

1. My newest Anti-Trans Legal Risk Map is here.

For trans adults, Kansas is the newest "Do Not Travel" warning, only the 3rd state to achieve that warning.

For youth, a change to the map increases risk to Medium in many states.

Nationwide risk remains extreme.
