During interphase, a eukaryotic cell multiplies its inventory of organelles and replicates its DNA (pink), growing in size.

During prophase, the cell's replicated DNA is supercoiled into chromosomes (pink) comprised of identical, paired sister chromatids.

During metaphase, the centromeres of the cell's chromosomes (pink) become aligned in a plane at its equator.

During anaphase, the paired sister chromatids (pink) separate and are pulled to opposite poles via microtubules (green).

During telophase, nuclear envelopes and nucleoli re-form around each pole's collection of DNA, chromatids uncoil back into chromatin, and the cell divides in two.

afracturedreality:

Muntjac Mitosis

These are fixed, permeabilized, and fluorescently-stained muntjac skin fibroblasts in either interphase or a phase of mitosis. The phases, going from top left to bottom right, are: interphase, prophase, metaphase, anaphase, and telophase.

During interphase, a eukaryotic cell multiplies its inventory of organelles and replicates its DNA (pink), growing in size.¹ Next, mitosis is activated and the cell enters prophase, during which its replicated DNA is supercoiled into chromosomes comprised of identical, paired sister chromatids. Eventually, the cell’s nuclear envelope disintegrates, and special microtubules (green) linking the kinetochores of chromatids to the cell’s poles develop. The cell then enters metaphase, during which the centromeres of its chromosomes become aligned in a plane at its equator. After passing a key mitotic checkpoint, the cell enters anaphase, during which the paired sister chromatids separate and are pulled to opposite poles. Finally, in telophase, nuclear envelopes and nucleoli re-form around each pole’s collection of DNA, chromatids uncoil back into chromatin, and the cell divides in two. Each daughter cell is at the start of interphase, and the cell cycle repeats.²

Alexa Fluor^® 350 phalloidin labeled actin filaments (blue) throughout each cell. An anti-α-tubulin antibody prelabeled with the Zenon^® Alexa Fluor^® 488 Mouse IgG₁ Labeling Kit marked microtubules (green), revealing their role in mitosis. The anti–Cdc6 peptide antibody prelabeled with the Zenon^® Alexa Fluor^® 647 Mouse IgG₁ Labeling Kit stained DNA (pink) in both chromatin and chromosomes.

Wartenburg Pinwheel corona

This is a Wartenberg pinwheel charged to a very high voltage by an industrial power source. Under these conditions, sharp points exhibit corona discharge into the air, with violet light streaming away from the pins. At a guess I’d say that the voltage was 30-50kV.

Today’s photo is from the Mongolian highlands. Surreal to see a frozen lake surrounded by sand dunes.

We never sit here under the weight of all this air, the 5 x 10^18 kg of atmosphere that sits above everyone on Earth, and say “Gosh, that sure is heavy!”

You don’t realize just how powerful that 1 bar (~100 kPa) of pressure is until a train car is filled with steam, allowed to cool, and then implodes ohmygod did that just happen?

For more implosion goodness, check out this awesome video from Veritasium.

Edgar Wright:

So on this very day [May 11], ten years ago, we began principal photography on ‘Shaun Of The Dead’ in London. To celebrate this we’ve decided to take you through every single day of production over the next month or two. Team Big Talk have gone through personal photos, stills, rushes and continuity photos to give you an unique day by day account of our shoot.
