Scientists have created a new way to generate powerful quantum interactions, achieving the first-ever demonstration of quadsqueezing.
This breakthrough makes previously hidden quantum effects visible and usable for advanced technologies.
Oxford scientists demonstrate first-ever quadsqueezing quantum interaction.
An international research team, including scientists from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), has achieved a methodological breakthrough in the study of superhydrides, a promising class of superconductors. For the first time, the team succeeded in analyzing lanthanum superhydrides under extreme pressure using nuclear magnetic resonance spectroscopy.
The research is published in the journal Advanced Science.
Superconductors are characterized by the fact that their electrical resistance vanishes below a material-specific critical temperature, allowing them to conduct electricity without loss. For most known materials, this transition temperature is below about 140 Kelvin (minus 133 degrees Celsius), which requires complex cooling technology for practical applications. Consequently, researchers are actively searching for materials that exhibit superconductivity at significantly higher temperatures.
Scientists have created a powerful new way to control quantum systems, achieving the first-ever demonstration of quadsqueezing—an elusive fourth-order quantum effect. By combining simple forces in a clever way, they made previously hidden quantum behaviors visible and usable, opening new frontiers for quantum technology.

Li et al. show that putting gold nanoparticles inside of LNPs causes marked improvements in endosomal escape efficiency, describe a likely mechanism, and test their complexes with two therapeutic contexts in mice. A simple innovation which could greatly enhance LNP delivery!
Lipid Nanoparticles (LNPs) effectively deliver mRNA to cells but suffer have low levels of endosomal release. Here the authors report on core-shell LNPs with ionizable lipid–coated gold nanoparticle cores with enhanced pH-responsive membrane disruption, endosomal escape, and cytosolic mRNA delivery improving therapeutic efficiency.
Bone immunity represents a dynamic interface where skeletal homeostasis intersects with systemic immune regulation. We synthesize emerging paradigms by contrasting two functionally distinct microenvironments: the marrow cavity, a hematopoietic and immune cell reservoir, and cancellous bone, a metabolically active hub orchestrating osteoimmune interactions. The marrow cavity not only generates innate and adaptive immune cells but also preserves long-term immune memory through stromal-derived chemokines and survival factors, while cancellous bone regulates bone remodeling via macrophage-osteoclast crosstalk and cytokine gradients. Breakthroughs in lymphatic vasculature identification challenge traditional views, revealing cortical and lymphatic networks in cancellous bone that mediate immune surveillance and pathological processes such as cancer metastasis.
Chinese scientists have identified two previously unknown lunar minerals from the 1,731 grams of moon samples returned by Chang’e-5 mission, marking another major breakthrough in deep-space research. The findings were announced on Friday at the opening ceremony of the 11th China Space Day. The two newly discovered minerals have been officially approved and classified by the International Mineralogical Association. They are named magnesiochangesite-(Y) and changesite-(Ce).
