I think we can all agree it’s time for the DALEK Relaxation Meditation for Humans video.

Viral images turn local bookstore owner into symbol of Minneapolis anger After federal agents fatally shot Alex Pretti, Greg Ketter drove to the scene to “be in that spot.” Images of the 70-year-old emerging from tear gas and shouting his anger quickly went viral.

After federal agents fatally shot Alex Pretti, Greg Ketter drove to the scene. Images of the 70-year-old, who owns Dream Haven Books & Comics, emerging from tear gas and shouting his anger quickly went viral.

So many people wanted to show their support that his website crashed.

I took this photo during a walk in the neighborhood one year ago.

Thanks. I didn’t know he wrote any SF.

I think we all agree that the next time someone makes a movie about someone stuck in a #timeloop, it should be also a movie about #curling.

SDB is sad to announce the passing of Gail R. Martin (1944-2026) after a short illness in San Francisco. Martin served as SDB President in 2007 and was the recipient the Conklin Medal in 2002 and the @FASEBorg Excellence in Science Award in 2011. bit.ly/4aIfu5d

Then I spent 8 years in her lab, learning about embryology , mouse genetics and we developed the Cre/loxP system to control gene expression in mice.

It was a great adventure , the best kind a scientist could have.

When I wrote to her, inquiring about a postdoc, I sent her the mock-grant. We ended up editing it together and getting funding. 5/6

I followed her work throughout my PhD in bacterial genetics with Issar Smith at NYU. For my qualifying exam, I wrote a mock- grant proposal on ES cells, based on Gail’s work. 4/6

But EC cells were too abnormal. This idea had to wait for Gail’s discovery and characterization of embryonic stem (ES) cells, as demonstrated by the Nobel Prize winning work of Capecchi, Evan’s and Smithies. 3/6

In a 1980 college class, where we read the primary scientific literature for the first time, I was enchanted by her mini review on embryonal carcinoma (EC) cells and the possibility of using them to generate a mouse. 2/6

I’m stunned.

Gail was a profound mentor, colleague and friend.

Very sad news. Gail Martin (1944-2026) was a figure in developmental biology. She pioneered the field of ES cells.
A great colleague, a friend and a lovely person.

Today, as is my habit, I went for a vigorous long walk, sometimes backtracking due to some unshoveled sidewalks. At one point, sweaty & breathing hard, thinking of the Olympic skiers at their run’s end, I looked for a patch of snow and ice to lay down upon.

But it was all grey and sooty.

I’ve grown to love various paths and trees in my neighborhood, as I’ve gone on many convalescent walks in the past year.

Here’s the same path on July 4 (2025), Nov 22 (2025) and Feb 1 (2026).

MN today:

- Liam kid’s blue bunny hat 4 the children & adult “little” people.

- Gas mask 4:
— prepared for chemical brutality, and
— protecting from face and identity surveillance.

Thanks to reporters 4 broadcasting this image today on MS NOW “Deadline Whitehouse”.

As we chopped and shoveled the snow and ice, I kept being reminded that most of the water in the solar system is rock.
