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.

It is commonly assumed that at least 96% of the genome of a multicellular organism has no functional role. A junk-dominated genome is the ideal place for evolution to randomly explore new functions and characteristics of the species. After all, who would ever think that a wise and all-knowing Creator would use 96% informational junk to define a human being or a mollusc?

Around 10% of Americans and 7% of Brazilians believe that the Earth is flat, that the moon landing was a hoax, and that those vaccinated against Covid-19 unknowingly received a microchip along with the vaccine. Several more percent remain uncertain about the veracity of official information.

Although the results do not seem spectacular yet, at least to the majority of the population, probably the most remarkable advances in the field of healthcare in the last 30 years relate to the mapping of the human genome (completed in 2003), the genome of other animal and plant species, and the development of bioinformatics.

Genetic testing is a new frontier in preventive medicine. But beyond this border, there lies a minefield of trial and error.

The daily horoscope is sometimes seen as a quasi-scientific method of predicting the future, other times as a preoccupation of childish adults, a way of calming one’s curiosity about tomorrow.

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...

Atheists frequently invoke the theory that in the Middle Ages, Christians (not just lay people, but even church leaders) believed in the myth of the flat Earth.

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?

Humans have only a fifth of the genetic material of an onion, and slightly more DNA than a mouse. Why would the Creator of life use five times more genetic information for an onion than for a human? And why would He create humans to be only slightly more genetically complex than mice? Aren't long and aimless evolutionary processes a better explanation for...

Sleep is perhaps the most important, complicated, and misunderstood physiological mechanism that keeps us alive.

Out of the endless series of events we experience, some we remember, and others we do not. Some often come to mind and we relish recounting them, while others we wouldn’t reveal for anything in the world.

If science were a religion, how violent would it be compared with Christianity?

The increased frequency with which doctors are encountering antibiotic-resistant bacteria is worrying. And it could affect an already precarious medical field—cancer treatment.

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. They were almost everything you could ask for in a set of housemates. Friendly, funny, respectful of your privacy . . . genuinely great people in almost every respect.
