Questions from a Korean magazine and answers (by PROFESSOR RICHARD LINDZEN)-1

Various sources give slightly different times for “The Little Ice Age,” but a good estimate is “The Little Ice Age spanned from about 1550 to about 1850” –– which would make it mid-16th Century to mid-18th Century. In the middle … Continue reading

Honey bees apparently can “understand” that “zero” is different from “5” and also different from “6”

The number “zero” is central to contemporary mathematics, as well as to our scientifically and technologically advanced culture. Yet, it is a difficult number to truly “understand”. Children grasp the symbolic number “zero” –– long after they start to understand, … Continue reading

Adaptive radiation is seen when the stickleback fish is exposed to a new niche that has no predators

Gene-environment interactions play an extremely important role in the adaptation of any species to a new or (rapidly) changing environment. For any living organism to colonize a new habitat or niche –– often it must rapidly adapt to multiple environmental … Continue reading

The gut microbiome is responsible for ketogenic diet-mediated protection against epileptic seizures

As often mentioned in these GEITP pages –– the microbiome (gut bacteria, which actually comprise more than 90% of all the DNA in us) has become increasingly realized to play an important role in gene-environment interactions. In today’s topic, the … Continue reading

Thinking of a Fluoroquinolone? Think Again

On these GEITP pages, we deal with gene-environment interactions, and a major subset of this topic is gene-drug interactions: efficacy, therapeutic failure, dose-dependent adverse drug reactions (ADRs), and dose-independent ADRs. All of these categories constitute the TRAIT (phenotype). The patient’s … Continue reading

Frequent Technology Use Linked to ADHD Symptoms

For years, I’ve been suggesting this –– as a probable causal factor for ADHD. And maybe ASD as well. Of course, it’s gene-environment interactions. The blinking/flashing lights are the environment. The person’s genetic make-up leads to his being “more or … Continue reading

ow did we modern humans (Homo sapiens) evolve?

These GEITP pages have often examined the latest advances in our understanding of how we modern humans (Homo sapiens) evolved. During the last three decades, our understanding has advanced greatly. Most research has supported the theory that Homo sapiens had … Continue reading

Frequencing of Amyotrophic Lateral Sclerosis (ALS) associated with statin usage

This publication –– concerning drug efficacy vs possible association with long-term undesirable drug toxicity –– has been ruminating in my mind for some weeks, so I asked for input on the statistical analysis. Statin cholesterol-lowering drugs are among the most … Continue reading
