  1. I've been thinking a lot about design lately -- next spring I'm teaching a course in the ethics of software design -- and I realized that even something like an iPad cover / stand can be right-handed, in a way.

    When the iPad is propped up using the cover in the photo, the home button has to be on the right. But I'm left-handed, so whenever I want to use the home button for the Touch ID, I have to reach across the tablet. It's not hard, but it's slightly awkward.

    People show a natural tendency to walk to the left

    ... as has been reported in the Guardian as well. There's a bug though. If I enter a room where I want to do a full circle, such as in a museum, I only make one decision, coming in through the door. If I turn left then, I'll have to walk clockwise from then on to follow the walls of the room. So left bias means more right turns?

  3. #Humans prefer to #walk #AntiClockwise
    scientists find – but reason is unclear
    From Spain to Japan, experiments have repeatedly shown a left-turn bias, but exact mechanic ‘is still an open question’

    1) they must check southern hemisphere!
    2) my son who has strong opinions on such things but can't communicate them practically always walks clockwise these days. He used to do longer walks either direction but now it's 30 mins clockwise.

  4. Field work in one of the smallest countries, Sao Tome, looking for one of the largest snails, unfortunately also endangered. Success! Giant Obo snail, bigger than your regular Giant African land snail - and sinistral coiling. PS individuals shown are only teenagers, not fully grown #snails #saotome #chirality

  5. Polenta is chiral. Clockwise stirred doesn’t mix with anti-clockwise, esp if done with the left hand. Something for @lowqualityfacts to ponder. #polenta #chirality #food #carboloading

  6. Garden snail genome now available. Amongst other things, a fantastic resource for trying to understand chiral variation in my lab snails.

  7. 🪞💡By leveraging the concept of chirality, or the difference of a shape from its mirror image, scientists from our school have engineered an optical metasurface that controls light to yield a simple and versatile technique for secure encryption, sensing, and computing.

    very interesting ... #chirality is kinda important when it comes to enatomeric D,L sugars 🧬 as well ?

    not sure how much it cost (delta G)🌡️ to change conformation 🚣 🪑?

  9. "Here, we show that chirality of either handedness can be induced in the nonchiral piezoelectric material boron phosphate..by irradiation with terahertz pulses. Resonant excitation of either one of two orthogonal, degenerate vibrational modes determines the sign of the induced chiral order parameter... Our findings offer new prospects for the control of out-of-equilibrium quantum phenomena in complex materials."

  10. "In this work, we explore the impact of chirality on spin angular momentum in hybrid metal/chiral molecule thin-film heterostructures. For this, we inject a pure spin current via spin pumping and investigate the spin-to-charge conversion at the hybrid chiral interface. Notably, we observe a chiral-induced unidirectionality in the conversion."

    intriguing. Could perhaps another far-fetched explanation for the #homochirality of #biomolecules be based on this? #science #physics #OriginOfLife #astrobiology

  14. Does anyone know if little-endian has any technical advantages? Big-endian machines are all but extinct these days (outside of IBM mainframes).
    Or is is just a case of having to pick one and stick with it, like how all life on Earth is made out of L-chiral amino acids and D-chiral carbohydrates?

  15. `Herein we provide a theoretical treatment for this phenomenon, presenting an effective spin-Hamiltonian for helical molecules like DNA and density functional theory (DFT) results on amino acids that confirm the dependence of J-couplings on the choice of enantiomer. The connection between nuclear spin dynamics and #chirality could offer insights for #molecular sensing... These results establish NMR as a potential tool for #chiral discrimination without external agents.`

    Structured #electrons with chiral mass and charge
    Physicists in Konstanz (Germany) have discovered a way to imprint a previously unseen geometrical form of #chirality onto electrons. The electrons are shaped into chiral coils of mass and charge
