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 flat Earth theory in the Middle Ages
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.
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."
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...
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?
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.
How lethal is COVID-19, and other (un)answered questions
There have now been over 12 million cases of COVID-19 infection globally, and half a million deaths. Researchers are constantly looking for new and better information to reduce the uncertainty around the virus.
The greed for knowledge
If science were a religion, how violent would it be compared with Christianity?
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.
How to sleep well in the age of anxiety
Sleep is perhaps the most important, complicated, and misunderstood physiological mechanism that keeps us alive.
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.
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.
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.
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.
How to develop your creativity every day
