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?

Humans and chimpanzees

Is the chimpanzee the human’s closest relative in the animal world? According to the theory of evolution, the answer is a categorical YES. Specialised literature abounds in generous estimates of human-chimpanzee genetic similarity, ranging from 96% to 99%. But how are these percentages obtained, what assumptions do they hide, and what do they mean beyond the evolutionary interpretation?

Gravitational waves and the inflation of certainty

On 17 March 2014, the science and technology blog of the prestigious newspaper The New Yorker announced, "A scientific breakthrough lets us see to the beginning of time". Lawrence M. Krauss, renowned physicist and author of "A Universe From Nothing: Why There is Something Rather than Nothing", commented in his article on the news that went around the world, heralding a landmark moment...

Future technology and current concerns

"[B]ut test them all; hold on to what is good" (1 Thessalonians 5:21).

The greed for knowledge

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

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.

Food and health with Dr Michael Orlich of the Loma Linda University Medical Center

When the founders of the Loma Linda University Medical Center in California laid the foundation, their purpose was somewhat paradoxical. Christians to the bone, and Adventists on top of that, they echoed the words attributed to the great reformer Martin Luther: “Even if I knew that tomorrow the world would go to pieces, I would still plant my apple tree.”

The sprouts of genomics

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.

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.

How to build a better brain

The first time he saw a living human brain, neurosurgeon Sanjay Gupta says it became “a powerful and life-changing experience."

Is sugar the most dangerous drug?

While few people can remember the details of their first hit, everyone can identify with the rush of satisfaction, the tingling delight that starts on the tip of your tongue and then courses through your entire body.

The God particle?

Very few ordinary people seem to be overflowing with passion for quantum physics, as the field involves a high degree of abstraction and relatively complicated mathematical equations.

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.

Will the metaverse really change the future?

There’s a 1995 clip from The David Letterman Show where Letterman is interviewing Bill Gates. Gates excitedly explains how the internet will change the future. Letterman is sceptical. He mentions a baseball game that had recently been broadcast live on the internet. “Does radio ring any bells?” he quips sarcastically, to laughter from his audience.
