The knots in question, the researchers wrote in their paper, were visible enough in images of the light wave data for them to identify the figure eights and toruses.

To create the knots, the researchers carefully tuned the up-and-down and side-to-side wave motion (the polarization) of two beams of light, partly using technology not unlike that found in polarized sunglasses. The knots formed around "polarization singularities" where the beams intersected, places where the side-to-side and up-and-down wavelengths were exactly equal, and a number of other wavelengths of light looped around them. At those points, light bent in the way the researchers wanted.
"We are all familiar with tying knots in tangible substances...," Mark Dennis, a University of Bristol physicist...said in the statement. "With light, however, things get a little more complex. It isn't just a single thread-like beam being knotted, but the whole of the space or 'field' in which it moves."
Dennis and his co-authors were interested in the topology, or the complex mathematical shaping, of that space. They found that the light formed more gaps when it knotted than expected, leaving spaces without significant energy from the beams.
Down the road, the researchers said, they hope to develop even more complex light knots; they hope this technology will speed the development of more precisely-tuned light sources.

They’ve never heard the advice “Don’t cross the streams.”?

Darn, long nails and phone keyboards! Slows me down.

Sounds like alot of hype about virtually nothing as written
‘knots’ ???
Yes light will form points where reinforced amplitude are present (when the phase of light through that small area is in the same direction by the photons passing through) — assuming you then put a measuring instrument right there . The dark spots are where the phase of photons present cancel each other out (again - to the observer).
This has been know for 100 years ? (easy to demonstrate with the multiple slit experiment with a prism to select a limited frequencies - done in physics 101 optics lab experiments)
So are they saying that such points have an effect on other photons passing near those points ? Why not say that if its what they infer they have done?
Rather more likely its : some variation of the effect mentioned above and just a way better control it and maybe be use to calibrate optical equipment or somesuch.
