The Oncomagnetic Device shrunk the 53-year-old’s glioblastoma brain tumor by 31% during his month-long treatment. (Image Credit: Houston Methodist Neurological Institute)   This seemed almost unreal. After researching it since the announcement, it appears to be real!   Researchers at the Houston Methodist Neurological Institute managed to treat a 53-year-old patient’s glioblastoma tumor through a wearable helmet that generates an oscillating magnetic field. Unfortunately, ...
University of Copenhagen researchers developed a new technique that detects the presence of nearby animals by collecting DNA samples in the air. (Image Credit: Nick Karvounis/Unsplash)   Evaluating an animals’ home to determine conservation needs often requires trail cameras, which aren’t reliable for capturing data on the animals’ habitat. There is a crucial need for non-invasive observational tools now that species are rapidly declining around the world. Researchers fro ...
When creating electronics projects, you might have wondered what the difference is between the two most used transistor types: bipolar junction transistors (BJT) and metal-oxide-semiconductor field-effect transistors (MOSFET) and what to choose for your project. You must consider many different factors to arrive at a decision. These include power level, drive voltage, efficiency, cost, and switching speed, amongst other things. This guide will discuss some of the differences between a PNP bipola ...
