As you may have heard, humanity’s addiction to plastic is becoming a problem. It’s been well documented for a while now that plastics are killing animals in the oceans and on the land. More recent studies have found that micro-plastic ... more

Apparently, just hours ago (as I write this) on Sunday, a large heretofore unknown asteroid (2018 GE3) raced across the southern sky, with absolutely no warning. Based on the amount of light it was reflecting, astronomers put its size at ... more

Did you know that it’s International Women’s Month? It is! Because of that, I wanted to take a look at a few women in Science that you should know. (If you don’t already.) more

So, we are about half-way through the Winter of 2018, which means it’s time for another Research Roundup! Of course, the first thing we have to talk about is last week’s successful launch of SpaceX’s Heavy Falcon rocket. After years of planning ... more

As I’ve noted in the past, there’s an undercurrent of anti-science that has always been a part of the American life-style. This undercurrent holds that science and the pursuit of knowledge is somehow undesirable or even “evil.” more

Last month, I told you about a new type of astronomy, one that uses Gravitational Waves to view cataclysmic events happening across the universe. This month, we’ve got news from old-school astronomers about a strange visitor from another star … more

As we went to print last month, news was swirling about an “Unprecedented” announcement that would be coming from the folks at the LIGO observatory. “LIGO,” if you don’t remember, is the “Laser Interferometry Gravitational-Wave Observatory.” more

To be honest, given the super storms in the Gulf, the gigantic wildfires out west and crazy spring-like weather that we’re experiencing here in mid-October, I strongly considered turning in a column that just said, “Climate Change is Real And ... more

Late last week, one of humanity’s most valiant emissaries, the Cassini Probe, met its end in the crushing atmosphere of Saturn. Cassini scientists dove the bus-sized robot into Saturn’s atmosphere on Friday, ending it’s almost 20-year mission in ... more

Finally! After being foretold for years, the mother of all Teachable Moments is finally here! On Monday, August 21st, 2017, between 1 p.m. and 4 p.m., there will be a Solar Eclipse visible from Chattanooga and the area to the north of the city. more

After failing miserably last month to give you a full-sized “Top 10” list of Human Parasites, I thought I’d try again, and see if I can make it to at least Seven Signs of Climate Change. So, here we go ... more

It’s that time again. Riverbend is here and so is my deadline. With that in mind, this month you get a cliché “Summer Top 10” list. But, given that it’s a list of Human Parasites, you know it’s gonna suck, literally and figuratively. more

As I’ve mentioned in the past, America has a paradoxical relationship with Science. On the one hand, we all benefit from the results of science, but, as a country, we seem to be less and less convinced of the value of science. more

As long-time readers know, space science is a particular interest of mine. One reason is that there’s always something interesting going on. In fact, the next few months are going to be particularly exciting as there are several events to look ... more

The past few years have seen an explosion in the number of exoplanets that we’ve discovered. In fact, it seems that almost every star we look at has one or more planets whizzing around it. For those of us of a certain age, it’s hard to believe ... more

So, this is a column about “Science,” but, what exactly is Science? Well, first of all, let’s talk about a few things Science isn’t: It’s not a Religion. Religion is based on Faith: An unshakable belief in things unseen and possibly even unknowable . more

Every now and again, there’s so much going on in the realm of scientific research, that it’s impossible for me to pick just one story to focus on. That’s right, it’s time for another Research Roundup! more

When I was a kid, I loved to read comic books. And, apart from run of the mill super-heroics, my favorite stories always involved crossovers where the heroes from the main book would meet (and usually fight with) heroes from a different ... more

In the movie The Matrix, our hero “Neo” (a.k.a, “The One”), finds out that the world he knows is actually a sophisticated computer simulation. The purpose of the simulation is to keep humans docile and supplying a constant stream ... more
