A team of researchers has proposed a new concept for magnet-based memory devices, which might revolutionize information storage devices owing to their potential for large-scale integration, non-volatility, and high durability. Details of their findings were published in the journal Nature Communications on March 7, 2024. Spintronic devices, represented by magnetic random access memory (MRAM), utilize the magnetization direction of ferromagnetic materials to memorize information. Because of their non-volatility and low energy consumption, spintronic devices will likely play a pivotal role in future information storage components.

Because (c) and its mirror image (d) are superimposable, they are the same molecule and achiral.

Gonna start using enantiomer terminology to talk about everyday chiral objects.

Ugh, all our bread knives are R configuration. I wish we had a racemic mixture so I could pick a knife with the right chirality to actually use the serrated edge without having to cut towards myself.

Watching a Death Stranding playthrough and I noticed that the word "chirality" has a lot of letters with bilateral symmetry, some both ways. So I really fast designed this little thingy.

Stripes in a flowing liquid crystal suggest a route to “chiral” fluids

Study finds chiral structures, with mirror-image configurations, can emerge from nonchiral systems, suggesting new ways to engineer these materials. [...] Hold your hands out in front of you, and no matter how you rotate them, it’s impossible to superimpose one over the other. Our hands are a perfect example of chirality — a geometric configuration by which an object cannot be superimposed onto its mirror image. Chirality is everywhere in nature, from our hands to the arrangement of our internal organs to the spiral structure of DNA. Chiral molecules and materials have been the key to many drug therapies, optical devices, and functional metamaterials. Scientists have until now assumed that chirality begets chirality — that is, chiral structures emerge from chiral forces and building blocks. But that assumption may need some retuning.

Lines of Asymmetry

From a distance we look roughly symmetrical, but we’re not completely – our faces might look odd if they were. Many of our organs must develop asymmetrically to take on their correct shape or move into place. But where does this asymmetry come from? These human cells are growing on circular stages under a high-powered microscope. Tiny 'bones' of actin (highlighted in green) in their cytoskeletons develop chirality – that is, they twist in a particular direction. Researchers find a group of proteins which sway these actin patterns. When they block the activity of profilin 1, for example, the direction of the actin swirl changes from anticlockwise (top left) to clockwise (top right). This switch is reversible (bottom left) and doesn't happen when blocking a similar protein, profilin 2 (bottom right). With these roots of asymmetry discovered, researchers may now trace lines of asymmetry throughout our development.

The synthesis of spirolides requires an understanding that these molecules are chiral (see chapter 17) and knowledge of how the functional groups contained in these molecules react.
