Forschende haben erstmals live und in sehr hoher Auflösung beobachtet, wie Grippeviren lebende Zellen befallen. Möglich war das dank einer neuen Mikroskopiemethode. Sie könnte nun helfen, antivirale Therapien gezielter zu entwickeln.

One of the greatest challenges in paleoenvironmental research is figuring out "how much of what we know on the modern is actually applicable to this?"
But there are finds, like this Silurian reef, we can say "ho, this is like a modern turbid reef." 🧪⚒️

Dass wir einen anti-feministischen Backlash erleben, ist leider auch die Schuld falsch verstandener Wissenschaft. Als "evolutionäre Psychologie" werden uns seit Jahren Geschlechter-Stereotype als evolutionär entstandene Fakten angedreht. Das ist gefährlich. (Thread)

The Dutch traded live eels to London starting in the mid-15th C., & quickly won a monopoly on eel sales in the city.

Well...by the 16th C., English regulations started calling ALL eel sellers in the city "palingmen" from the Dutch word for eel: paling. 1/2

Electrification + heat recovery = massive efficiency gains. This is the kind of behind-the-scenes innovation that quietly transforms entire sectors.

The late Miocene possibly had lower athmospheric pCO2 than we have right now (but higher than pre-industrial), but that was enough for there not to be permafrost in North Greenland.
Once a local threshold is reached, that is enough sometimes. 🧪

So what's that to do with silly memes and fun alt-text?
If I can tell a good story, & show our history with eels, then maybe I can get you interested in saving them.
I hope seeing them in our past will make you want to see them in our future. 2/2

Despite the fact that nearsightedness has a hereditary component, environmental factors play into as well. One of those factors is not exercising looking into the distance at early age.
