Yuck. Cold Spring Harbor Lab meeting "celebrating" 50 years of recombinant DNA is a #manel #YAMMM

With a history of issues in sexism (e.g. Watson) at CSHL this is sad. And bonus featuring Lander w/ his own history of issues as session chair & panel discussion leader Years ago I routinely felt the need to critique Cold Spring Harbor meetings for their gender bias - eg see --- I had thought they had gotten better in response to critiques but clearly notphylogenomics.blogspot.com/2016/03/if-you…

Thank you @sacbee for this critically important editorial:

Masking in public should be mandatory, even if California officials refuse to take action sacbee.com/opinion/editor…

Attention @Chancellor_May @ucdavis - it is time for UC Davis to do the right thing I agree:

"While deaths and hospitalizations are lower thanks to the availability of vaccines and treatments, we invite new risks by ignoring what we have learned after two-plus years and 1 million deaths."

Looking for studies on impact of masks and vaccination on COVID transmission in classrooms.

I found this discussion of a recent paper - wondering if people have other pointers out there or comments on this study - thanks:

Thank you to the people speaking up against this horrible comment from Kipnis saying that if you critique an institution (like his) after you leave, you are disgusting. Such a bad take. eg see response from @zjayres

Well, in case you missed it. Two weeks ago I posted about the disastrous and dangerous and incompetent new University of California pharmacy benefits "system" which warned me, two months after the fact, that they were cutting off coverage of my insulin 1/n This was, well, quite stressful and really poorly handled by UC. And the pharmacy benefits provider they had switched to - Navitus - was a true and epic disaster in many ways. 2/n

Dear @UofCalifornia @ucdavis

This is NOT OK.

I just got a notice by letter in mail that my insurance will no longer cover the insulin I have been getting "as of January 1, 2022". Letter was dated in February and was received after March 1, 2022.

This is NOT OK. Although I do have a grace period to get the insulin at my old price until March 31, 2022. It would have been nice to have been told about this before 3/1.

This is NOT OK either.

1. Last week I had two doctor's appointments in Sacramento in the AM. And then a 2 hour Zoom from 10-12. I decided it would be nice to do the Zoom while in some scenic spot & I remembered I had seen reported of a pretty rare bird at the Nimbus Fish Hatchery close to where I was 2. I don't normally chase reported birds - just not my thing really - but I had to find somewhere to go and I do read some of the rare bird reports so I headed off to So after my second appointment I zipped on over to the Nimbus Fish Hatchery. wildlife.ca.gov/Fishing/Hatche…

I am dismayed by the people, including leaders, who are treating #Omicron as "mild" & therefore not a big deal ignoring the unvaccinated & unboosted, long covid, at risk groups and that it is not "mild" for everyone, just on average has less severe effects to the vaccinated See for example this thread from @IanRicksecker for some more details

When I was a senior at @harvard in 1990 I started an "Environmental Issues" journal as part of activities leading to the 20th anniversary of Earth Day. I hoped to get EO Wilson to be our faculty sponsor. I phoned his office and arranged a meeting with him via his assistant 1/n I figured, with a prof. like him this would be a very brief meeting. But instead I got to his office, and there was Wilson, and he was so excited about something. He had a new book out on Ants he wanted to show me. And we looked it over for like an hour. 2/n

Well, from what I can tell, most people, institutions & officials in the USA are in denial regarding the oncoming tidal wave of Omicron infections that are (1) already happening & (2) will soon massively increase. Come on everyone - we need to slow this down. 1. Limit indoor gatherings.
2. Especially stop maskless indoor activities. JFC people.
3. If you have to be indoors w/ people outside your household: ventilate, filter, mask.
4. Boost
5. Test early and often.
6. Quarantine w/ any hints of exposure / symptoms.

Just donated to @inaturalist. Incredibly grateful to the people behind it and the people who participate in it. It is an incredible community and also has helped me have something positive to focus on every day during the pandemic.

inaturalist.org/donate?utm_cam… I made the donation in memory of my father Howard Eisen & wrote

Need a #Nature break? Well, yesterday we had a reprieve from the rain I zipped on up to Sacramento Wildlife Refuge for a brief outing. Here are some of the better pics:

jonathaneisen.smugmug.com/2021/2021-12/2… As the cover photo shows, got some nice sightings of bald eagles there including a few in flight and a few sitting forever ... I particularly like the ones of one soaring over the hills such as this (even though a bit further away) jonathaneisen.smugmug.com/2021/2021-12/2…
