There's actually about ten images in this set, but Lemmy will only let me pick one, so I hope I got the best one of the set!

Thank you for seeing my work!

Snowy Owl (Bubo scandiacus)

A female Snowy Owl arrives at her nest to warm her young on her nest on the tree-less Arctic tundra. Our only white owl is our heaviest (up to 6.5lbs/2950grams), breeds and winters further north and has one of the most poorly understood movement patterns.

Some of these Arctic owls winter on Arctic ice, others on territories on the tundra and some migrate to the northern Great Plains, Great Lakes, while others (especially young) irrupt or migrate into the northeastern and even the Pacific Northwestern states.

This study from MIT used geo data collected from cars in Milan, Italy, to check the effectiveness of 30 km/h zones in reducing speed.

The first conclusion is that the signs don't work: 85 percentile speeds are all over the place in 30 km/h zones in Milan, as shown in the figure below:

The second step was finding correlations between speeds and street features extracted from openstreetmap. Results are as expected: narrow, short, curvy sections correlate with lower speeds, as do 1 lane vs more, one way vs 2 ways:

The final step is also interesting: the authors made a model to predict the compliance of 30 km/h speed limit on streets that are 50 km/h at the moment. Useful for urban planning to understand if charging an area to 30 km/h would need structural interventions (like bumps, narrowing of the street...) or not:

There is so much more in the article, I suggest to read it fully.

When Silence Has Wings

Between moss and marble, where time breathes softly, she sat—a long-eared owl, shrouded in shadow and silence.

Her eyes mostly closed, as if dreaming of old stories known only to the wind.

But in a fleeting moment—a yawn, almost like a whisper—she opened her eyes, looked at me...

As if to say, "I see you."

A moment so still, yet full of life.

It existed far before humanity, was summon by humans who thought they could use it and controll it. Its mind and body altering. invisible and (somewhat) impossible to grasp fully.

This statement was made after Poland was not invited to a number of events where the details of providing military assistance to Ukraine, including those related to supplies to Kiev through Polish territory, were discussed. This really offended the leader of Poland.

"Both Ukrainians and our allies (in NATO. — Ed.) simply believe that the airport in Rzeszow and our highways belong to them. I'm sorry. It's not theirs. This is ours. In this regard, if someone does not like something, then we close it - and goodbye.

We have repairs. We are closing the airport in Rzeszow, and make deliveries to Drop Ukraine by sea, by air, by parachutes, if you don't think you need us, " said Duda, quoted by RIA Novosti.
