Organic luminescent radicals enable bright circularly polarized light in the near-infrared region
Circularly polarized light has properties that make it useful in a growing range of technologies, from next-generation 3D displays to bioimaging tools that can detect signals deep within living tissues. One way to produce this kind of light is with the help of chiral molecules—compounds that have a mirror-image form to which they cannot be perfectly superimposed. Among these, small organic molecules (SOMs) offer tunable emission wavelengths.
Luminescent radicals represent a promising type of SOM for red and near-infrared circularly polarized luminescence (CPL) emission. One particular family of radicals, tris(2,4,6‑trichlorophenyl)methyl (TTM)‑based radicals, is inherently chiral and a natural candidate for CPL.
In practice, however, these molecules fall short on multiple fronts, with tradeoffs between stable chirality, high emission efficiency, and durability under operating conditions.
Scientists Solve 100-Year-Old Schrödinger Mystery About Color Perception
New research into how humans perceive color differences is helping resolve questions tied to a theory first proposed nearly 100 years ago by physicist Erwin Schrödinger. A team led by Los Alamos National Laboratory scientist Roxana Bujack used geometry to mathematically describe how people experience hue, saturation and lightness. Their findings, presented at a visualization science conference, strengthen and formalize Schrödinger’s model by showing these color qualities are fundamental properties of the color system itself.
“What we conclude is that these color qualities don’t emerge from additional external constructs such as cultural or learned experiences but reflect the intrinsic properties of the color metric itself,” Bujack said. “This metric geometrically encodes the perceived color distance — that is, how different two colors appear to an observer.”
By formally defining these perceptual characteristics, the researchers believe they have supplied a crucial missing piece in Schrödinger’s long-standing vision of a complete model capable of defining hue, saturation, and lightness entirely through geometric relationships between colors.
ABA signaling is involved in the regulation of BSK1 stability mediated by the UBP24-PUB25/26 module in Arabidopsis
Li et al. report that Arabidopsis BSK1 negatively regulates ABA signaling. The stability of BSK1 is dynamically controlled by PUB25 and PUB26, a process likely regulated by BAK1 phosphorylation, whereas UBP24 stabilizes BSK1 by removing ubiquitin chains. ABA shifts this balance toward degradation by inducing the accumulation of PUB25/26.
The maternal-fetal interface as an immunological barrier: Structure, regulation, and breakdown
The maternal-fetal interface is a specialized immunological barrier that integrates tolerance, defense, and regulated inflammation throughout gestation. Distinct immune populations mediate implantation, immune homeostasis, and parturition, while dysregulation can result in chronic placental inflammation, a consequence of barrier failure, characterized by infiltration of maternal T cells into placental/fetal tissues.
Gaussian Splatting is my new favourite thing, so I hassled an ex-Epic artist to tell me everything he knows about the low-cost ‘photo-real’ rendering technique
Open source engine PlayCanvas is what Iakov Sumygin used to build that browser-based FPS. Resources like this strengthen Schindelar’s case, particularly as the engine just introduced SplatTransform 2.0, a tool that offers “fully automated, lightning-fast generation of high-quality collision for your splats.” Without a collision mesh, players could otherwise phase through the environment, so this is yet another option that streamlines the pipeline between scan and interactive assets.
“Gaussian Splatting training—meaning the reconstruction process after capture—can reproduce real-world appearance in ways that traditional scanning methods struggle with or cannot handle properly,” He tells me, “We can now capture and represent things like hair, semi-transparency, translucency, subsurface scattering, fine foliage, and other complex visual phenomena that are extremely difficult to reconstruct as clean geometry with traditional texture workflows.”
“This direct connection between captured real-world data and a production-ready, real-time representation is what makes Gaussian Splatting so interesting,” Schindelar says, “It is not just a rendering trick—it changes the entire capture-to-delivery pipeline.”
