Inspired by the toot from @matt303 - here's a dreadful photo of me in about 1978.
If I remember correctly, I was doing T4 (Thyroxine) assays using radioactive Iodine on serum samples. This would have been using the Amersham International testing kits. The machine / display may well have been some sort of geiger counter.
The photo was definately taken at the old Papworth Hospital in Papworth Everard in #Cambridgeshire

Man wearing a white coat holding a pen is in front of a device with numbers showing. There is a white container with a metal box above it with a radioactivity symbol. There are shelves on the wall. The man has strange hair and even stranger glasses. He's trying hard not to laugh at the way he looks.

1921 nace Marie Maynard Daly fue una bioquímica estadounidense y la primera mujer afroamericana en los Estados Unidos en obtener un doctorado - Ph.D.- en Química (Columbia University, 1947).
Daly hizo contribuciones importantes en cuatro áreas de investigación: la química de histonas, síntesis de proteína, las relaciones entre colesterol e hipertensión, y la absorción de creatina por las células musculares.

New #OpenAccess publication in the spotlight:

➡️ Intramolecular feedback regulation of the LRRK2 Roc G domain by a LRRK2 kinase-dependent mechanism

🔗 doi.org/10.7554/eLife.91083.4

We talked to one of the #authors, Arjan Kortholt from our faculty of #Science and #Engineering, about the article, preprints, open #PeerReview, open access, and #OpenScience in general.

The biological world is awash in #chemical signals.

Some molecular messages find their targets; most linger unread in the environment.

But sometimes, other #species — chemical eavesdroppers, bystanders or visitors — can pick up and interpret the signals in their own way.

If the message is powerful enough, the impact can ripple out across an #ecosystem.

First Roll of Film - Franconia Sculpture Park, MN : Skallagrim by Peter Lundberg | Pentax KX, 50mm, Fuji 400

У Міннесоті скульптурних парків – як комарів у червні, куди не глянь, натрапиш на якесь сучасне мистецтво. Але мистецтво тут настільки сучасне, що кожен похід у парк перетворюється на інтелектуальний квест - це інсталяція чи хтось просто забув частину паркану?

Йдеш стежкою, бачиш щось величезне, абстрактне, трохи іржаве і думаєш: “О, цікаво, що хотів сказати автор?”. А потім виявляється, що автор – це випадок, а ти пів години милувався випадковою конструкцією, яку привезли на ремонт.

Ось ця конструкція нагадала мені хромосому, хоча скоріш за все автор мав на увазі щось зовсім інше, враховуючи назву

A large, weathered sculpture resembling a DNA spiral with two elongated, twisted arms reaching upwards stands in an open field of dry grass. The structure has a rough, textured surface, possibly made of stone or concrete, and contrasts against a bright blue sky dotted with fluffy white clouds. A dense line of evergreen trees in the background forms a natural barrier, while a few small structures and metal frames are visible in the distance. The image has a nostalgic, film-like quality with grain and subtle color shifts.

The received wisdom has always been that spacecraft need to be as microbe-free as possible, but our @ScienceDesk shared this New Scientist story that says the situation might be more complex. “On the space station, astronauts often get rashes, unusual allergies, fungal or bacterial infections, as well as activation of latent viruses such as Epstein-Barr,” writes Michael Le Page. Professor Pieter Dorrestein of the University of California San Diego told Le Page his theory is that the immune system needs to be periodically “pinged.”

And now something completely different. Yes sorry, I post various topics (see bio). My apologies to those who only follow me for my anti-fascism. ❤️
