Cell theory is the most fundamental principle in biology, one stating that all living organisms are composed of similar primary units called cells. It is a universally accepted theory about the organization and structure of all organisms. Modern research and molecular biology, with their advanced too...
The modern theory includes the two basic components of the classic version and then adds the following: Organisms can be unicellular, composed of one cell, or multi-cellular, composed of many cells. When cells divide, the hereditary information they contain, DNA, is passed from cell to cell...
The theory behind free radicals is that they can lead to the imbalance between free radicals and antioxidants(抗氧化剂). "Another mini-science lesson for you: Antioxidants are natural or man-made matters that can help delay or prevent some types of cell damage. They're often found in fruits...
subsequent reality. To improve its predictive ability, the brain builds an internal representation of the world. In his theory, human intelligence emerges from that process. Whether influenced by Hawkins or not, generative AI works exactly this way. And, startlingly, it acts as if it is ...
But will the BIG discovery happen? Will this dark DNA hold the secret to a form of life that we have never known before? Will Dark DNA reveal a lifeform that is all around us, influencing our every day lives in unknown ways, yet has been missed by science?
What modern-day discoveries are from quantum physics? Who discovered electromagnetism? What did Michael Faraday invent? What subatomic particle did Ernest Rutherford discover? What contribution did Niels Bohr make to atomic theory? What is quantum electrodynamics?
For example, the venom in Platypus is not archaic but totally original, neither squamate nor mammal-type (O’Brien 2008), the coelacanth fish is originally modern in its reproduction mode, being ovoviviparous (Casane and Laurenti 2013). The term “panchronic” (e.g., Janvier 2007) has ...
It should not be thought, however, that anarchism is only a critique of modern civilisation, just “negative” or “destructive.” It is also a proposal for a free society. Emma Goldman expressed what might be called the “anarchist question” as follows:“The problem that confronts us today...
populations is changing, often to an extreme degree. In this Essay, we propose that the disappearance of these ancestral indigenous organisms, which are intimately involved in human physiology, is not entirely beneficial and has consequences that might include post-modern conditions such as obesity ...
My guest today is Joseph Henrich, a professor at Harvard, and an expert on the evolution of human cooperation and culture. I am a big fan of his book, “The Secret of Our Success” and he just published a new one called the Weirdest People in the World about people who fall under ...
