A Reminder That The Inside Of The Cell Is As Beautiful As Outer Space.

Psychology: Why do people do the thing?

Sociology: How do people who do the thing interact with other people who do the thing?

Anthropology: Who else has done/is doing the thing and where are they?

Philosophy: What is the meaning of the thing? Where did the thing come from?

Mammals both produce milk and have hair. Ergo, a coconut is a mammal.

I Recently read About these amazing glow in the dark creatures in the newspapers and thought it was worth sharing 1. Saprobe Panellus Stipticus, Fungi:

Found in Asia, Australia, Europe and North America, the bio-luminescence emitted by the Saprobe fungi that grows on decaying wood...

Next week I’ll give a presentation on the Researchers Night at Eötvös Loránd University, Hungary with the title: “Chemistry of light and the light of chemistry”.

During this presentation one of my favorite dyes will be also presented: Nile Red. However, just as usual, the 1000 USD/gram price was a bit over our budget, so I had to make it.

The raw product was contaminated with a few impurities, but a fast purification, by simple filtering the mixture through a short column helped a lot and ended up with a +95% pure product.

At first I concentrated the product from a dilute solution on the column as seen on the first pics. It’s interesting to see, that it has a different fluorescence in solution (faint orange fluorescent)  and while it’s absorbed on the solid phase (pink, highly fluorescent).

After all the product was on the solid phase, I added another solvent and washed down the pure, HIGHLY FLUORESCENT product. Everything else, what was mainly products of side reactions, stuck at the top of the column as seen on the second pics and the gifs.

Also here is a video from the whole process in HD: https://youtu.be/W0Lk5jkd_B0

Viscosity can have a notable effect on droplet impacts. This poster demonstrates with snapshots from three droplet impacts. The blue drops are dyed water, and the red ones are a more viscous water-glycerol mixture. When the two water droplets impact, a skirt forms between them, then spreads outward into a sheet with a thicker, uneven rim before retracting. The second row shows a water droplet impacting a water-glycerol droplet. The less viscous water droplet deforms faster, wrapping around and mixing into the other drop before rebounding in a jet. The last row switches the impacts, with the more viscous drop falling onto the water. As in the previous case, the water deforms faster than the water-glycerol. The two mix during spreading and rebound slower. In the last timestep shown, the droplet is still contracting, but it does rebound as a jet thereafter. (Image credit: T. Fanning et al.)

Cyanea capillata by Alexander Semenov 

daniel stoupin, a doctoral candidate in marine biology at the university of queensland, has photographed a variety of coral species from the great barrier reef using full spectrum light to reveal fluorescent pigments that would otherwise be invisible to the naked eye.

coral growth rates in the great barrier reef have plummeted 40 percent in the last 40 years, a result, according to a recent study, of increased ocean acidification. 

since the beginning of the industrial revolution, about one third of the carbon dioxide that has been released into the atmosphere as a result of fossil fuels has been absorbed by the oceans, where it in turn prevents coral from using a mineral called aragonite to make their calcified skeletons. 

new modelling has also shown that if ocean waters continue to warm by even one degree, which most now see as unstoppable, the coverage of corals on the great barrier reef could decline to less than 10 percent, which is a level too low for the reef to mount a recovery. 

further complicating matters for the coral is the plastic detritus left by humans which now litter the oceans and which the coral now consume. unable to expel the plastic bits and thus take in nutrients, the coral slowly starve. a recent study found that each square kilometre of australia’s sea surface water is contaminated with approximately 4,000 pieces of tiny plastic.
