    Heart rate variability

    Byscientist

    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

    Byscientist

    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

    Byscientist

    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…

  • Measurement technology

    Byscientist

    One of the oldest measuring technology is the sextant. A small device that measures the angle of the sun at noon, can predict the latitude of the earth. It is also possible to figure out the longitude and from there the exact location. In the past, using the stars enabled figuring out the location with…

  • Vibe coding ultimate.

    Byscientist

    Alex Kozyr has been using vibe coding to create web apps. His website is : https://kozyrai.com/. He presented his methods at Venture cafe and also showed off his work and his link: https://kozyrai.com/#/work/kozyr-timeline. That was a good demonstration of timeline. This simple webabb puts together a timeline for whichever events that you selected. In tis…

    Phages as antibacterial

    Byscientist

    Bacteriophages are viruses that attack bacteria killing them. They are inanimate and can be considered dead till they infect the bacteria where they multiply. Phages were approved by the FDA in 2006 for their application in food to control Listeria infections. Link to paper: https://www.gastrojournal.org/article/S0016-5085%2806%2902235-9/fulltext This has continued for sometime, since multiple strains can be…

    Technology – implementation

    Byscientist

    Consider In-vitro fertilization (IVF). The research for that had begun in early 1900’s till the first successful IVF transplantation and successful birth in 1978. It took several years for the technology to get adopted till nearly 50 years later when about 1-2% of all births are now IVF enabled. One of the issues that bogged…

  • Aquaporin

    Byscientist

    Aquaporin is a protein that is a water channel in cell membranes. One company with the same name is using the protein in artificial membranes to extract the water. In typical reverse osmosis process, the water is pumped at a high pressure on one side of the membrane and that pushes the relatively free water…

  • Discoveries and Publicity

    Byscientist

    A university in Netherlands, Eindhoven institute of technology discovered a protein that is a variety of luciferase that generates light based on the concentration of the analyte. They also modified it so that another protein that is integrated to the same protein converts the light that is emitted to another color based on the binding…
