Those who patiently tolerate my posts may wonder about my preoccupation with small details in nature/objects/textures Well there is the intrinsic aesthetic & beauty BUT mainly - looking at the small helps me cope with facing the - at times seemingly impossible - big issues

A great 🚲 related thread for some holiday quiet moments

It's time once again for my annual #treebybike post. This is the 12/19/42 cover of @newyorker.com, so one full year after the attack on Pearl Harbor. This would be the first real Christmas alone, or without a family member, for millions in the US. Gas and tire rationing had begun earlier that year.🗃️
A magazine cover, with a single illustration covering the entire page, and no headlines over the top. A hand illustration -- perhaps watercolors -- shows a snowy day and an empty road heading towards the viewer. In the distance, a cozy christmas tree store surrounded by green trees, some cut and some still standing, with a cozy cabin behind. In the foreground, a jaunty woman with hat and sunglasses and scarf bicycles toward us, with a christmas tree horizontally held on the front rack of her bike and a black scotty dog running alongside. She and the shop and the cabin are all in pastels; pinks and purples and white. Her white scarf and hat match the white snow on the store and cabin. It is a cheerful, jaunty, undaunted tone, and evenly spaced big snowflakes float down over it all. At the top the magazine name, The New Yorker, the date Dec. 19, 1942, and the Price: 15 cents. At the bottom is the signature of the artist, Garrett Price https://en.wikipedia.org/wiki/Garrett_Price

The #HelsinkiBikeCommute may be paused for a while, but we still got out on the 🚲 for an early morning festive hot chocolate & gingerbread on the beach in Helsinki.
Looks far warmer than it was!

This is news that makes me happy. It really feels most of the time that taxonomy is in a bad place. But in reality, it seems that in the last decades, the rate of species description has been the highest it ever was! 🧪

Link: www.science.org/doi/10.1126/...
Cumulative numbers and rates in new species over time across living organisms. (A) The total (cumulative) number of species known in each year and (B) the number of species newly described each year. The analysis includes 1.9 million species, including only extant, accepted names, and excluding viruses, fossil taxa, and species with unknown publication dates.

Never thought I’d have a favorite copepod… but behold Sapphirina! These little copepods are so iridescent they appear bioluminescent! When diving for plankton in the Gulf of California on this expedition, we see them as tiny specks of bright blue light. #zooplankton #oceanography #christmasatsea 🌊

Close up photo of algae on the surface of small pools of water created by ocean waves. The photo looks like a scanning electron microscope pic, but this was taken with a simple point n click camera. Photo of the pools/environment is in the comments.

Had an proposal for funding rejected 40 min ago
After 41 years in this game:
I believe in all applications I submit
I never expect to get funded
Am not surprised when I do not get funding
Still feel disappointed when don't get funded
Do not dwell on the rejection for more than an hour

Moving on...
