Electricity can heal wounds three times as fast (2023)
Chronic wounds are a major health problem for diabetic patients and the elderly – in extreme cases they can even lead to amputation. Using electric stimulation, researchers in a project at Chalmers University of Technology, Sweden, and the University of Freiburg, Germany, have developed a method that speeds up the…

Deriving the piano keyboard from biological principles using clustering
Once upon a time we were creatures in the wilderness and we evolved the ability to hear sounds. Now here's an interesting thing, if you hear a sound of frequency f and others of frequency 2f, 3f, etc then there's a good chance these sounds come from the same object, due to the physical principle of resonance . And so…

Gene-silencing tool shows promise as a future therapy against prion diseases
MIT Whitehead and Broad Institute researchers designed an epigenetic editor that can silence the prion protein gene, which could potentially be developed into a therapy against fatal prion diseases. The same approach could be used against other genetic diseases.

UK chemist on Elsevier's ban on textmining
This is the first post of probably several in my concern about textmining. You do NOT have to be a scientist to understand the point with total clarity. This topic is one of the most important I have written about this year. We are at a critical point where unless we take action our scholarly rights will be further…

Monitoring marine litter from space
Every 60 seconds the equivalent of a lorry-load of plastic enters the global ocean. Where it goes after that remains largely unknown. But a new ESA Discovery study reported in Nature Communications has proven the concept of monitoring floating plastic litter using satellites.

How to build a brain – An introduction to neurophysiology for engineers
How does the brain work? While neuroscience provides insights on small-scale processes and overall behavior, we don’t know much for sure about the learning and processing algorithms in between. In this blog post, I will give an introduction to what we know. Let’s take an engineering perspective and play evolution: How…

This is the story of one computer professional's explorations in the world of postmodern literary criticism. I'm a working software engineer, not a student nor an academic nor a person with any real background in the humanities. Consequently, I've approached the whole subject with a somewhat different frame of mind…
