    A human instinct seems to support collection. It may have originated from collection of food and collecting for the hard times…but… the collection seems to progress into other objects. A visit to the beach implies collection of shells. Why? It is not clear why any individual collects. Some of it has to do with shiny…

    Novel Catalyst

    There are many reactions in biology that are catalyzed by enzymes but there are other reactions in industrial chemistry that use industrial catalysts which have primarily been platinum based. A paper in Nature https://www.nature.com/articles/s41467-026-68432-1 promises a unique shaped catalyst that can split H-H bond and other reactions. It is a unique structure and promises to…

    Relaxin is a 6kd 2 chain peptide hormone produced by ovary and placenta in females tha help remodel connective tissue but also promotes vasodilation and has cardioprotective and renoprotective effects in animal model via Nitric oxide pathway. Relaxin-2 signaling via GPCR RXFP1 has been investigated as a drug for its antifibrotic and vasodilatory actions. RXFP1…

    Heart rate variability

    By definition, heart rate variability is the time between each heart beat. This is called the R-R interval and shows the beat modulation of the sino-atrial node whose time variation is controlled by the autonomic nervous system. This matters because sympathetic (fight or flight) or parasympathetic (rest and digest) activity governs cardiac dynamics. A higher…

    Knowledge graphs

    Knowledge graph is a way of representing information where entities/nodes (people, places, products, concepts) are linked by relationships/edges (works, creates, has ). It is a semantic network that captures facts and context. There is also an ontology that defines different types of node/edges and defines what types exist and how they relate. These are used…

  • Docker

    Docker allows developers to deploy their applications in a sandbox to run on a host system with all the dependencies with a very low overhead. Typically that used to be done by virtual machines, but docker makes it more secure and faster without the virtual machine overload. Like any other complex system, there are many…
