"It breaks your heart. It is designed to break your heart. The game begins in the spring, when everything else begins again, and it blossoms in the summer, filling the afternoons and evenings, and then as soon as the chill rains come, it stops and leaves you to face the fall alone." - AB Giamatti.

Scientists identify first virus to infect Legionella, revealing evolutionary origins of Legionnaire's disease U of T researchers have made the first discovery of a virus that infects Legionella pneumophila, the bacteria that causes Legionnaires’ disease.

Congrats to my better half @legionella.bsky.social and his lab and collaborators on this cool discovery! TLDR, they've identified and re-animated a bacteriophage of Legionella pneumophila, a bacteria long thought to not be susceptible to phage attack. Check it out! 🦠

Elio Schaechter was one of my heroes. His 1958 paper with Ole MaalΓΈe and Niels Kjeldgaard (fondly known as β€œSMK”) is a North Star for so much work in my group. A wonderful scientist, great communicator, and a very kind person. May his memory be a blessing.

Adventures in owning a 32-yo Malibu Flightcraft...

You don't need to be a boat mechanic to guess which of these water pump impellers was old, which is new, and why the engine was overheating last week.

Also, thanks to Amazon.com and youtube, I had the boat running again in less than 24 hours.
