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.
Non-functional DNA: the playground of evolution?
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?
Why do some people believe the earth is flat?
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.
My daily horoscope really fits! True or false?
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.
The redefinition that conquered the world
For Carl Sagan, renowned astronomer and militant atheist, God's place in the universe was certain: "The cosmos is all that is, or ever was, or ever will be." For Richard Dawkins, exponent of the "new wave" of atheism, true science is necessarily atheistic and materialistic. This paradigm dominates the scientific world today.
Hope, a legacy of another world
Hope can be palpable and elusive at the same time, both reasonable and independent of logic. Yet this independence from logic is not synonymous with indifference to reason, but a victory over it. Hope has its own logic, one that changes lives for the better.
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 risks of overrelying on genetic testing
Genetic testing is a new frontier in preventive medicine. But beyond this border, there lies a minefield of trial and error.
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.
The greed for knowledge
If science were a religion, how violent would it be compared with Christianity?
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. 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.
How to sleep well in the age of anxiety
Sleep is perhaps the most important, complicated, and misunderstood physiological mechanism that keeps us alive.
Evolution before our very eyes | Part 2
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?
Evolution and creation: closer to the core of the controversy
I got acquainted with Ariel Roth as a writer, but I also got to meet him as a human being. I discovered neither fanaticism nor nervousness, neither doubt nor ideological speech in Roth, an octogenarian who still looks in detail at each new subject appearing on the agenda of the debate between evolution and creation. He maintains an unflagging desire for honesty and...
A new theory of evolution—or several complementary theories?
"Strange as it sounds, scientists still do not know the answers to some of the most basic questions about how life on Earth evolved. Take eyes, for instance. Where do they come from, exactly?" These are the words with which an extensive article published by The Guardian in June 2022 begins.
