Wiley today releases the Wiley Registry of Mass Spectral Data 2026, the new edition of one of the world’s largest and most trusted mass spectral reference databases for identifying unknown chemical compounds

Black holes are usually born in violent cosmic events — but theory also allows for microscopic versions emerging from delicate “critical states” of spacetime itself. Researchers from TU Wien and Goethe University Frankfurt have now derived exact mathematical formulas describing these strange spacetime structures, sometimes dubbed “spacetime crystals,” using a surprising trick involving infinitely many dimensions.

A newly developed organic semiconductor device can both generate electricity from light and emit bright visible light, as reported by researchers from Science Tokyo. By carefully designing a material where energy losses are suppressed, the team achieved efficient power conversion and electroluminescence simultaneously, demonstrating a multifunctional platform with potential applications in displays, sensors, and energy-harvesting technologies.

For the first time, therapeutically effective medications are now available for Alzheimer’s disease. Effective symptomatic therapies also exist for Parkinson’s disease. However, a prerequisite for successful treatment is early diagnosis – ideally through a simple blood test conducted as part of a preventive screening, even before clinical symptoms appear. A research team led by Professor Klaus Gerwert from Ruhr University Bochum, Germany, has developed just such a blood test. It is based on the immuno-infrared sensor, a novel platform technology to which the Journal of Physical Chemistry B dedicates its cover story in its issue from April 24, 2026.

EPFL researchers have developed a way to use holograms to guide laser light for ultra-efficient, fast, and precise volumetric 3D printing. The innovation enables cell-compatible, high-resolution 3D printing at scales suitable for biomedical applications.

The mechanism of high-temperature (T_C) superconductivity is a key challenge in condensed matter physics. Recently, Chinese scientists made significant progress in the study of high-T_C nickelate superconductors.

For the first time, scientists observed a nodeless superconducting gap and discovered electron-boson coupling by measuring the electronic structures of Ruddlesden-Popper bilayer nickelate superconducting thin films. These results provide crucial evidence for two fundamental issues in the mechanism of high-T_C nickelates: “superconducting gap symmetry” and “superconducting pairing mechanism”.

Since their discovery in the 1950s, metallocenes — chemical compounds where a metal atom sits ‘sandwiched’ between two carbon rings — have been at the heart of organometallic chemistry research, finding applications in catalysis, materials design, energy, sensing, drug delivery and more. Yet knowledge of their formation has been limited, due to the transient nature of their unstable intermediates.

Published in the Journal of the American Chemical Society (JACS), researchers from the Okinawa Institute of Science and Technology (OIST) have reported the first full structural characterization of a doubly ring-slipped reaction intermediate in the formation of a metallocene. With its unusual structure, the characterization provides new evidence of how metallocenes may form, break and react, presenting design opportunities for stimuli-responsive, metallocene-based materials for a wide variety of potential applications.
