Neuroscientists have always presumed that learning and memory depend on strengthening or weakening the connection points between neurons (synapses), increasing or decreasing the likelihood that the cell is going to pass along a message to its neighbor. But recently some researchers have started pursuing a completely different theory that does not involve changing the strength of synaptic…

How many times a day do you check the time? Estimates are that people between the ages of 18-34 check the clock between 50-74 times a day! Staying in sync is essential for any complex system; whether it’s a machine, social organization, or transportation system, chaos would erupt if the intricate processes involved were not precisely coordinated in…

The much-anticipated recent announcement of Elon Musk’s development of a brain-computer interface (BCI) device, called Neuralink, was a media sensation.  The fact that Musk, a successful businessman who makes advanced technology a commercial reality, is investing in BCI is significant and newsworthy.  This area of research has been around since the 1970s, and brain stimulation…

On Sunday, March 17 2019, CBS 60 Minutes broadcast an alarming report on the Cuban/Chinese, sonic/microwave/neuroweapon attack on US embassy staff and their families.  The report is an example of how a once credible press has been supplanted by tabloid sensationalism and fearmongering.  The program featured interviews with staff and family members at the US…

We know that Homo sapiens (meaning the wise one) co-inhabited the earth with Neandertals. What’s more, DNA analysis proves that men and women of both species (or subspecies if you prefer), mated. Of course, there was no Valentine’s Day back when the daily grind for a working man meant bringing down a woolly mammoth with a sharp stick.…

It is fascinating to consider that there was a time when such commonly used words as “pre-heat,” “download,” and “phone,” did not exist.  More surprising, perhaps, is that the first recorded use of these words in print, and 205 others in the English language, was in Scientific American magazine. That’s according to the Oxford English…
