The firefly luciferase is being used as a 'reporter gene' here, to reveal the Kalanchoe's 24-hour rhythms in the lab. Otherwise they are invisible.
Actually the luciferase glow is not directly visible either! It's so faint that the video was taken with super-sensitive cameras, closer to astronomy kit than to your smartphone. These are transgenic plants, developed for lab science in my now-#EdinburghUni colleague Jessica Pritchard's PhD, with James Hartwell in Liverpool.
She reported this cool new science in a #preprint last year:

Ok, yeah, I'm not done processing my anger over liberals doing shit like this. So this historian sees a rise in right wing violence, sees the US government carrying out ethnic cleansing, sees a rise in white supremacist terrorism, and then says, "oh yeah... this reminds me of a time right around the 1920s. Hum... yeah, ANARCHISTS fighting the government! Yeah, that's the same thing."
FFS, IT'S THE RED SUMMER! If you want a parallel between today and some horrible time in US history, TALK ABOUT THE RED SUMMER. The point of the language of dehumanization that the right uses, the point of all the anti-black and anti-emigrant rhetoric, is that it leads to genocide. Trump already carried out an act of genocide (#USPol

Eine neuerrichtete Fahrradstraße in Bochum. Der Gehweg ist extra für den erhöhten Parkbedarf der Autos schmaler eingerichtet worden.
Was fehlt, sind Abstellmöglichkeiten für Fahrräder. Die Kreativität der Radfahrenden ist gefragt.
wie will man den Anteil des Radverkehrs erhöhen, wenn man ihn keine sichere und einfache Möglichkeit bietet, von zu Hause aus loszufahren?

Have a beautiful Day of Aphrodite aka Venus' Day aka Frigg's Day aka Friday 🌹
"The fourth star is that of Venus, Lucifer by name. Some say it is Juno's. In many tales it is recorded that it is called Hesperus, too. It seems to be the largest of all stars."
