The excellent radio program Innovation Hub had an episode that dealt with various aspects of the issue of separating children from their parents at the borders, starting with how the US went from being a country with open borders to one, in the 1920s, with strict quotas.

Many of you will have heard of the famous Stanford prison experiment in 1971 when Philip Zimbardo, a psychology professor at Stanford University, randomly assigned one group of students to be inmates and the other group to be guards who had total power over the prisoners for two weeks. The setting was a mock prison (actually the basement of a university building). But after six days the experiment had to be called off because, as claimed by Zimbardo, the ‘guards’ used such sadistic methods against the ‘inmates’ that the latter were on the verge of breakdowns. The experiment has been cited numerous times to warn of the dangers of giving people unchecked power over others and the need for prison reform.

Jennifer Barfield, a professor of assisted reproductive technologies at Colorado State University, clearly explains how it can come about and what led to the development of the technology that has made it possible. The key point is that in addition to the DNA that comes from the father and the mother, the fertilized egg also contains mitochondrial DNA (mtDNA) that plays a vital role in producing energy.

Albert Einstein’s travel diaries that he maintained on his travels in China and Japan and Sri Lanka (then Ceylon) in 1922-1923 have just been published and they contain descriptions of what he saw that are deeply at odds with the enlightened views we normally associate with him. He makes statements that can at best are described as xenophobic and at worst as racist.

Readers may recall my post from back in February about the mysterious sounds that were causing headaches (literally) to US embassy personnel in Cuba. It led to all manner of speculations about the Cubans themselves unleashing, or allowing some other nation to unleash, some high tech Cold War-type sonar devices on them. The fact that the evidence produced was highly vague and that the Cubans had no motive for doing such things did not stop the wild speculations.

This video of a tornado touching down in Laramie, Wyoming last week is awe-inspiring. I had thought that tornados start in the clouds and then touch down on the ground but in this video at the 18-second mark you see that there is also a bottom-up element, a sliver that starts on the ground and joins to the larger part coming from the top. The tightness of the funnel cloud is indicative of the massive destructive power that it can unleash for anyone and anything that has the misfortune to lie in its narrow path.
A couple of weeks ago, I had a post about how the rate at which clocks run is affected by the strength of the gravitational field in which they are in. So a clock on the surface of the moon would run faster than an identical clock on the surface of the Earth because the gravitational field there is less than the field here.

Questions like the above are inherently ambiguous and will not have an answer that satisfies everyone because of the difficulty of defining what we mean by the word ‘science’ even with the added qualifier ‘modern’. The latest issue of New Humanist has an interview with David Wootton, professor of history at the University of York and author of the book The Invention of Science, who takes a stab at it and argues that “it happened between 1572 (when astronomer Tycho Brahe saw a new star in the sky) and 1704 (when Isaac Newton drew conclusions about the nature of light, based on experiments).”

A court case in Cleveland into the death of a five-year old girl has taken a strange turn in which the defense has asked the judge to be allowed to present as an expert witness in forensic science someone who believes, among other things, that the Earth was created in just six days as the Bible says.

I am of the age group where we encounter the phenomenon of people having Alzheimer’s or other forms of dementia on a fairly regular basis, either because our parents or the parents of friends or even in rare cases with people closer to our age group who succumb to early onset forms of the disease. As a result, the conversations often assume the inevitability of our own serious cognitive decline. The attitude is that it is a question of ‘when’ not ‘if’, and various strategies are bandied about as ways of delaying it.
