chiral

Like, maybe just the mirror image of the knot, if the knot is a chiral knot?

One of the GC columns has a chiral stationary phase.

Actually only 19 of the 20 standard amino acids are chiral.

Not everything is chiral, for example take the mirror image of a water molecule : it's the same thing.

They are not saying all life-bearing planets must have chiral molecules, and therefore we can tell whether a planet has life based on the light.

Fun fact: chiral molecules affect left and right circular polarized light differently.

One of SAM's gas chromatograph columns is chiral: it can separate left-handed molecules from right-handed ones.

No one is stating that live must produce large numbers of chiral molecules, but that large numbers of chiral molecules are expected to be produced by life.

Rather unusually, thalidomide has a nitrogen atom as its chiral center.

How can you distinguish between two chiral molecules and two identical molecules one of which has been rotated 180 degrees with respect to the other?

They are saying that if a planet exhibits light coming from a source with lots of chiral molecules, then the only known explanation is life, and we can conclude it is life.

No wonder I haven't gotten it :DBut in all seriousness, I wonder if the homogenous form Zyrtec is as effective as the chiral-ically singular Xyzal.

For example, I recall that I first came across the words 'chiral' and 'enantiomer' in textbooks well before I heard them being used by professionals who knew how to pronounce them correctly, again diacriticals would have quickly solved the problem.

The article linked doesn't have a lot of detail, but i'm impressed that someone has pushed through the standard reflexive though that either chiral form was equally likely and recognised that actually the universal has handedness that could have influenced the outcome.

Normally that cilium enforces torquoselectivity -it only rotates in one direction which establishes chiral directionality, but a certain genotype disables its rotation, so the orientation of your body is a factor of random chance based on how your cell was rotating at the single cell level.

This is so totally bonkers it is hard to know where to start, but perhaps an easy place is: how would you go about isolating a single quark and a single gluon in the horrible nonperturbative mess that is the QCD vacuum[0].If you want to program the nucleons in the nucleus, you can switch your description to chiral perturbation theory[1], which is weakly coupled, but you need to be able to shoot individual pions at individual nuclei, which would be extremely difficult, and might require enough energy to liberate the target nucleon from the rest of the nucleus, anyway, destroying your "computer".
