Greetings from the fourth dimension: Scientists get a glimpse into 4D crystal structures using surface wave patterns
In the illustration, the tesseract (a four-dimensional cube) and the “shadow” it casts on an airplane, a quasicrystalline discovered by Schechtmann. According to Professor Barthal, “The fact that quasicrystals are the “shadow” of high-dimensional periodic crystals is not new in itself. What we discovered is that projections include not only structure but topological properties such as vortices. . ”). Credits:…

Unexpected discovery of collagen structures indicates greater diversity than previously believed
Characterization of A, B-CRT and C peptide assemblies: Credit: ACS Central Science (2025). doi:10.1021/accentsci.5c00018 Collagen, the body’s most abundant protein, has long been considered a predictable structural component of tissue. However, a new study led by Jeffrey Hartgarin and Tracy Yu of Rice University, in collaboration with Mark Kreuzberger and Edward Egelman of the University of Virginia (UVA) is likely…

The bacteria in the polymer form cable-like structures and grow into a living gel.
A 3D rendering taken with a confocal microscope shows non-motile E. coli bacterial cells developing serpentine “cables” as they grow in a polymer solution. A scale bar is included. Credit: Sebastian Gonzalez La Corte et al./Princeton University/California Institute of Technology Scientists at the California Institute of Technology and Princeton University have found that bacterial cells growing in a slime-like polymer…

Research identifies illicit financial risks in Premier League club ownership structures
Credit: Pixabay on Pexels The Premier League is currently vulnerable to new investors and team owners who may have gained wealth from illegal activities. This is according to a new paper raising concerns about the competition’s owner and director’s test (commonly known as the ‘fitness and suitability’ test), which says: ‘The complex and opaque structure makes it difficult for EPL…

New electron microscopy technique reveals complex spin structures on femtosecond timescales
Melon pair spin vector. Unlike the rapidly oscillating electric and magnetic fields of the surface plasmon polariton that underlie this spin texture, the texture itself is temporally stable over the duration of the plasmon pulse. The horizontal separation of the two (red) maxima is approximately half the wavelength of the surface plasmon polariton (390 nm). Credit: P. Dreher et al.,…

Bioengineers and chemists design fluorescent 3D printed structures with potential medical applications
The ring-shaped “nanohoops” emit light of different colors depending on their structure. Credit: University of Oregon Researchers at the University of Oregon have mixed fluorescent ring-shaped molecules into a new 3D printing process, using the simple process of mixing eggs and flour to make pancakes. The result is complex light-emitting structures that support the development of new classes of biomedical…
