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.
Memories that shape the future
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.
A lesson in natural sciences
The red horizons are shattered. But much more subtle dangers loom for the present and the future. In most Christian countries, theology has declared a truce with evolutionary atheology and has devised a foolish and deadly compromise that is neither atheism nor true Christianity.
COVID-19: Should we care about the environment in the midst of an economic crisis?
Our planet may be fittingly compared to the 1994 film, Speed: A bomb is planted on a bus and rigged to explode when the bus slows to less than 80 kilometres per hour. The bus barrels through Los Angeles, hitting obstacles and endangering the lives of passengers and pedestrians until a solution is found.
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.
How to develop your creativity every day
Even if half of us refer to creativity as a rare trait that only the other half has, in reality, creativity is much like a muscle: the more we use it, the more creative we become.
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.
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.”
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...
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.
The greed for knowledge
If science were a religion, how violent would it be compared with Christianity?
COVID-19 and our low-risk but endangered children
All COVID-19 statistics lead to the same conclusion: the young ones, our children, are at the lowest risk of getting ill or dying from the virus. That’s comforting. But the pandemic does pose a certain danger to them.
Antibiotics: Blind optimism is dangerous
The increased frequency with which doctors are encountering antibiotic-resistant bacteria is worrying. And it could affect an already precarious medical field—cancer treatment.
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.
Evolution: Impossible
Dr. John Ashton of Newcastle, Australia, is a compelling example of a serious research scientist who bases his beliefs regarding the origins of the universe and life on the Bible.
