Vacuum in optical cavity can change material's magnetic state without laser excitation      (via sciencedaily.com)     Original source 

Researchers in Germany and the USA have produced the first theoretical demonstration that the magnetic state of an atomically thin material, ?-RuCl3, can be controlled solely by placing it into an optical cavity. Crucially, the cavity vacuum fluctuations alone are sufficient to change the material's magnetic order from a zigzag antiferromagnet into a ferromagnet.

Visualizing fungal infections deep in living host tissue reveals proline metabolism facilitates virulence      (via sciencedaily.com)     Original source 

Scientists have published the first successful application of 2-photon intravital microscopy (IVM) to image the dynamics of fungal infections in the kidney of a living host. The study reveals that the opportunistic human fungal pathogen Candida albicans requires the ability to metabolize proline, an amino acid obtained from the host, to mount virulent infections.

Research connecting gut bacteria and oxytocin provides a new mechanism for microbiome-promoted health benefits      (via sciencedaily.com)     Original source 

Researchers found that the hormone oxytocin, known to be involved in regulating feeding and social behavior and until now to be produced mostly in the brain, is also produced in the human intestine. Furthermore, gut resident bacteria L. reuteri can affect the production of gut-made oxytocin, providing the first insights into a mechanism by which these bacteria can influence human health.

Optical-fiber based single-photon light source at room temperature for next-generation quantum processing      (via sciencedaily.com)     Original source 

Single-photon emitters quantum mechanically connect quantum bits (or qubits) between nodes in quantum networks. They are typically made by embedding rare-earth elements in optical fibers at extremely low temperatures. Now, researchers have developed an ytterbium-doped optical fiber at room temperature. By avoiding the need for expensive cooling solutions, the proposed method offers a cost-effective platform for photonic quantum applications.

New study sheds light on the molecular mechanisms underlying lipid recycling within cells      (via sciencedaily.com)     Original source 

Our understanding of how cells recycle lipids through autophagy -- a form of cellular degradation -- has grown significantly, thanks to a recent study. Using yeast as a model organism, the researchers explored the molecular mechanisms leading to the degradation of the phospholipid bilayers making up the cell membranes. Their findings improve our understanding of cellular degradation processes and related metabolic disorders.

Scientists create special 'telomouse' with human-like telomeres      (via sciencedaily.com)     Original source 

Researchers introduce the 'Telomouse'. By making a subtle genetic alteration in standard lab mice, they've made the mouse telomeres, which protect the chromosome ends, more closely resemble those in humans. The Telomouse model, developed by incorporating a genetic variation from a mouse species with naturally shorter telomeres, provides a valuable resource for in-depth aging and cancer research. This discovery promises to reveal new insights into the genetics of aging and may contribute to enhanced longevity and well-being.

Intestinal bacteria metabolite promotes capture of antigens by dendritic cells      (via sciencedaily.com)     Original source 

Dendritic cells are immune cells that capture and present antigens to T cells, activating an immune response. Researchers have discovered that short-chain fatty acids produced by intestinal bacteria regulate a crucial step in this process, the extension of dendritic 'arms.' This breakthrough finding could potentially lead to the development of disease prevention strategies involving beneficial bacteria and new drugs targeting the regulation of dendritic cell function.

Mammalian cells may consume bacteria-killing viruses to promote cellular health      (via sciencedaily.com)     Original source 

Bacteriophages, also called phages, are viruses that infect and kill bacteria, their natural hosts. But from a macromolecular viewpoint, phages can be viewed as nutritionally enriched packets of nucleotides wrapped in an amino acid shell. A study suggests that mammalian cells internalize phages as a resource to promote cellular growth and survival.
