Recently visited the Glass Flowers at Harvard, a collection of 4,300 extraordinarily realistic glass models of plants crafted by the Blaschkas, a father and son team of sculptors
That’s right, these are all made primarily of GLASS — a fact difficult to accept given how accurate & lifelike they are

I am confused by the language. The text says people will not be considered affiliated if the affiliation is terminated within 90 days of the enactment of the act (should it happen).
How can this apply to co-authorship on papers?

Statistical significance != effect size
[to its credit, the article isn't about that -- it's explaining physics approachably, and it does predict effect size. But this example reminds me of so much science that never actually looks at whether a magnitude could matter.]

Great example of how ecology is done, including how open questions about effects of climate change are fairly examined (tl;dr: many birds doing ok, but not all)
How are Pacific NW mountain birds responding to climate change?

There's a lot going on in the world. But a positive thing is that when our local fusion reactor shoots something that could fry our electronics:
1) Earth still manages to shield us
2) We go outside, take pictures of the pretty lights, and show them to our friends.

The Sun just produced an X5.1 class #SolarFlare. This is the largest flare of 2025 so far, and 6th largest of the past two years. It triggered a strong ‘Radio Blackout’ and moderate ‘Solar Radiation Storm’ at Earth, and released what is most likely an Earth-directed coronal mass ejection!
