Do you know how much your digital footprint costs? Lessons from a hacker who changed his mind

After I published the analysis regarding the mirage of cryptocurrencies, I received an irresistible invitation: an IT consultant offered to give me a demonstration, in front of the laptop, of the connection between cryptocurrencies and the black market. The exercise turned into a three-hour discussion on cybersecurity and ended with unexpected conclusions about identity theft for political purposes.

What does the Bible say about climate change?

During the COVID-19 lockdown last year, I lived with some messy people. I’d moved into a house that I shared with a wonderful couple of brothers.

Evolution before our very eyes | Part 1

Bacteria are becoming increasingly resistant to antibiotics; some butterflies and fish are developing new colours for better camouflage; and a series of laboratory experiments have revealed small but significant changes in various microorganisms. Are these phenomena conclusive evidence of evolution unfolding before our eyes?

The big picture

Fossil layers seem to be consistent with some independent phylogenetic analyses, radiometric dating methods seem to be consistent with inferences based on the DNA "molecular clock," continental drift over millions of years seems to be consistent with the distribution of species and fossils on Earth... and the examples go on. If the evolution of life is not a real phenomenon, how can we...

The faith of a scientist

The field of science was flourishing, and amid its youngest and brightest, one student in particular consistently topped physics and chemistry courses, took its academic prizes and was courted with offers of scholarships by prestigious universities. His trajectory was toward the heights of the scientific world.
