Eric Green, head of the nation’s top genomics research institute, looks back on how far the field has come and shares his bold vision for the future.
Optical fibres made of topological photonic crystals allow improved versatility and control across the modes and polarization of light they transmit. Compositionally, photonic crystals contain bandgaps to prevent the passage of light relative to specific wave energies and momenta much like an on/off switch. In a new report now published on Nature Light: Science & Applications, Hao Lin, and Ling Lu at the Institute of Physics at the Chinese Academy of Sciences transmitted pure “single mode” light across a large frequency range via a topological feature known as a “Dirac vortex.” The concept can lead to applications that transmit light signals more stably across long distances. While the work is theoretical at present, the researchers suggest the use of fibers made from silica based on stack-and-draw methods or three-dimensional (3D) printing technologies to fabricate and test these theoretical concepts.
Understanding the nodal lines and Weyl points in a photonic crystal fibre.
Photonic crystal fibres rely on the endless variety of two-dimensional (2-D) crystals for their functionality. The concept of topological photonics based on robust waveguides can inspire new fibre concepts including the development of a one-way fibre inside a magnetic, 3D photonic crystal. In this work, Lin and Lu introduced a topological photonic crystal fibre (PCF) resembling the Dirac vortex topological cavity in its cross-section using 2-D photonic crystals. The Dirac vortex fibre is an ideal design to develop ultrabroadband single-polarization single-mode (SPSM) fibres due to the singlet mid-gap dispersion within the bandgap. The scientists eased the fabrication step by introducing a simplified design of only four capillary silica tubes to finally achieve an octave-spanning SPSM.
This will help ensure that SSDs don’t suddenly just stop working one day. 😃 At least you get to back up your data.
It’s only available for data centers for now though. In the future, we may get our own when they perfect the technology.
If a NAND chip fails, these new SSDs detect it, move the data somewhere else on the drive, and keep on functioning.
Nothing to see here-just our future robot overlords dancing to retro PMJ tracks before they take over the world.

You are an apogee of Earthly Nature encompassing numerous generations of humans as well as preceded non-human terrestrial life, sitting atop the tree of life… and so is everyone else who lives today. We all can be regarded as archetypes for future generations as well, or perhaps a “developing pattern,” if you intend to live indefinitely long. At any rate, genetically and anthropologically speaking, we all are one humongous extended family. #Timescape #HomoSapiens #ExponentialPedigree
This demographic research provides a host of quantifiable properties of the human species as a whole for further visualizing the data via certain graphs and diagrams. 5 trillion subjective years would constitute the ‘Timescape’ of Homo sapiens up to the p.
