Biologists have built one of the most detailed pictures of pregnancy's true toll on the body.

Read the full story: https://go.nature.com/4iKaWxZ
A graphic titled "the body's slow recovery from childbirth" "Researchers examined 76 physiological markers in hundreds of thousands of pregnancies, looking at how look it took for each marker to settle following delivery" ~47% test results stabilished within 1 month of delivery 12% results settle in 4-10 weeks ~41% results take more than 10 weeks to settle

An in vivo imaging technique can track the way molecules move through the nucleus

Live-cell super-resolution microscopy reveals how molecules enter and exit the nucleus
The nuclear pore complex is the gateway to the nucleus of cells. Now an in vivo imaging technique can track the way in which molecules move through this complex.

This is good and beautiful. (Except for time flowing downwards from the top, which makes me dizzy.)

At last! Finished page: how a star forms, what fuels it, & how it forges new forms into being! A star is a momentary reversal - a wellspring of possibilities that makes life possible. This took me some time to figure out to say the least - but geeked to be done & move onward! #Nostos #Unflattening 2
Comics page on how a star forms, what’s going on inside, and how it’s generating new elements over its lifetime - and a reversal of entropy’s downward flow towards disorder. There’s a drawing of a star that’s about the width of the page in the center - realistic on its outside and diagrammatic on the interior. Running through it from top of page to bottom of page - is an hourglass like shape with various panels, sort of like greek meanders ornamenting it that detail various parts of the narrative here. The interior of the star shape is in four quadrants (a bit of the middle and the center are carved out by the hourglass, which i’ll get to next). upper left quadrant is a diagram of the force of gravity versue the resistance pressue of atoms being shoved together - represented by black arrows drawing inward and white drawing outward - which make a circular star shape complete with the tails of the black arrows as rays of the star. the background for this panel is a warped grid as space would be warped by this massive object. Upper right panel is a closeup on just a few of these white and black arrows - and within them - filled with more closely packed particles and then also tiny arrows pressing from outside. Lower left panel has the path light takes to leave a star - a brownian motion trail, bouncing around randomly in all sorts of directions before eventually leaving the star. The final panel within the star is a more realistic depiction of what the regions within the star might look like. On the hourglass, there are periodic stripes with panels inside them - in the other spaces, we see circles as simplified particles falling down this funnel and getting closer together as they near the center (as with hydrogen falling into a star). the first row of panels is a series of hourglasses - with sand running down. The next one is a quick retelling of the birth of the universe to the first filaments. Then the hourglasses again, now they are spinning, sand running uphill. T…

100 years from the birth of #quantum #physics and it's the International Year of Quantum #Science and #Technology 🎉

This nice article summarises nicely the early days and has some interesting bibliography cited. I hope readers will enjoy it!

The Tumultuous Birth of Quantum Mechanics
The creation of modern quantum mechanics was a messy business in which many of the participants did not grasp the significance of their own discoveries.

Done with #X, so let's see how this works now. So far I can see a somewhat vibrant #scientific community here 🙂!
