Star Trek: Discovery Trailer! The Jay Dee Show 30

Another week gone, and some videos to watch! Not as many as I’d hoped, though. But I think we’ve got some good stuff here. Actually, there were only two videos, one on each channel. But they are both worth watching.

On my main channel, I uploaded one video. And it had to do with Star Trek: Discovery! You see, the first trailer was released, and I had some interesting impressions about it. So, check out my Star Trek: Discovery trailer reaction!

On my science channel, I finally resumed uploading videos. I explained what happened in the past month, but also have a big request. And I want to ask you, too. Is there a science topic or question you’d like me to answer? If so, let me know in the comments section below or on the video. Check it out!

More to come next week. Definitely some Star Trek, a top 5 list about science fiction, Authors Answer, and some science! And a very, very special video that will be up tomorrow. It deserves its own blog post.

Let me know what you thought of these videos in the comments section below. And what did you think about the Star Trek: Discovery trailer, if you saw it?

You Can’t Please Everyone – Comments

Over the last couple months, I’ve been receiving a lot of comments on two posts which talk about things that bring a lot of controversy. One is about politics, the other is about climate change.

I’m better at talking about climate change, so I don’t have a problem rebutting climate change deniers’ claims. One comment questioned what I said in the post and provided some information about Mt. Etna’s CO2 output, thinking he won the “debate.” Well, the information he told me matches what was said on Snopes, as well as scientific sources. It only confirmed what I’d said. That backfired.

And about Snopes, if I refer to a Snopes article, don’t say it’s not a legitimate source. You know why? The information they give references scientific journals, government research, and other legitimate sources.

But then, we get to the political post. The topic doesn’t matter, but what does matter is how people comment. I was insulted in a rather crude manner. The first rule on this blog for comments is this: Do not insult anyone. The second rule: Be civil. These people broke those rules.

If you want to have a constructive conversation, then behave. Use intelligent arguments, not reactionary ones. Don’t use all caps on random words. Whenever I see comments like that, I can pretty safely assume that the person is irrational and illogical. All caps don’t make an argument stronger, it makes the person look like they’re shouting. Don’t call me or other commenters idiots. Behaviour like this makes a person less credible. It’s not worth my time to debate with people like this.

Now that I got this off my chest, I’ll return this blog to normal.

Everything Derailed! The Jay Dee Show 27

Things were going so well. The A to Z Challenge had begun, I was getting videos out on time, and then it happened. Derailment. I caught a cold so strong that I had very little energy. And just as I’d recovered, I started working 10 straight days on something that was physically demanding. Again, energy sapped. But I should be getting things back on track now!

First of all, my main channel has had no new videos. I have a couple coming up, though. Already recorded!

Moving on to my science channel, there are 3 videos to report to you!

First is the letter B. It’s 10 Facts about Bees!

Moving on the letter C, it’s 10 Facts about the Canada Goose.

And then for the letter D, it’s 10 Fact about DNA.

They’re all about biology, surprisingly. I already have the E video ready to edit and upload, which I’ll do tomorrow.

What do we have in store for the next week? Videos! I plan on continuing the A to Z Challenge, even though it’s finishing. I’m not quitting. For my main channel, it looks like I may have a tag video to do, as well as some vlogs. I’ll be working on the regular weekly videos, and maybe more! I should get back to doing Japan videos, too.

So, which video did you enjoy the most?

D Is for DNA

This post is coming a day late. I hope that’s not a problem with the rules of the A to Z Challenge! You see, I have some foreign DNA in my body. The common cold. I was too tired to get the video and post up last night. But here it is now! For the letter D, I’m talking about DNA. How many of these facts did you know?

And here are the facts:

  1. DNA stands for deoxyribonucleic acid.
  2. A DNA molecule is made up of two bipolymer strands wrapped around each other to form a double helix.
  3. There are four nucleobases represented by the letters C, G, A, and T. They are cytosine, guanine, adenine, and thymine.
  4. Nucleobases pair up, A with T and C with G to connect the two DNA strands to form the double helix.
  5. Only 2% of human DNA codes protein sequences. The remaining 98% have other various functions, which would require another full video to talk about.
  6. The species with the largest number of chromosomes is the ciliated protozoa with 29,640,000.
  7. The species with the fewest number of chromosomes is the jack jumper ant with only 2. But that’s for the females. Males are haploid and have only 1, the smallest number possible.
  8. Humans have 46 chromosomes, but other great apes, including chimpanzees, gorillas, and orangutans, have 48.
  9. More than 8% of the human genome is made up of retrovirus sequences.
  10. There is a 4% difference in the genomes of humans and our closest relatives, chimpanzees and bonobos.

Let me know in the comments section below what you knew.

E Is for ´╗┐Europa

Even though the A to Z Challenge is over, and I took a huge break, I’m going to finish it. A lot has happened over the last couple months, but it’s back! Today is the letter E, and I’m talking about Jupiter’s moon Europa! Did you learn anything new?

  1. Europa is the fourth largest natural satellite of Jupiter.
  2. It was discovered in 1610 by Galileo Galilei, along with the other three Galilean satellites.
  3. The surface of Europa is the smoothest surface of any world in the Solar System, consisting of water ice.
  4. Europa orbits Jupiter in just 3.55 days, with one side always facing Jupiter, as it’s tidally locked.
  5. Beneath the ice crust is an estimated 100 km deep ocean of salt water. But it isn’t clear if the ice is thick or thin. However, the amount of water on Europa is about two to three times the volume of Earth’s oceans.
  6. Europa has a weak magnetic field, best explained by Europa’s salt water ocean.
  7. Tidal heating from the interactions of Europa with Jupiter and the other Galilean satellites warms the interior of the moon, possibly resulting in hydrothermal vents at the floor of the ocean. This has led scientists to suggest that life may exist in Europa’s ocean.
  8. Europa most likely has an iron core and a rocky mantle.
  9. Observations by the Hubble Space Telescope provide further evidence of subsurface oceans, as plumes of water have been seen erupting to 200 km above the surface.
  10. Europa has an oxygen atmosphere. But it’s very thin, providing a surface pressure of only 0.1 micropascals.

C Is for Canada Goose

What other bird says “Canada” to you? Maybe the loon? Well, how about the Canada goose? For the letter C, I am talking about the Canada goose! Check out the video, which includes some bonus video of a v-formation I managed to catch.

And here are the facts. How many did you know?

  1. This large goose is native to the arctic and temperature regions of North America.
  2. It’s been introduced to other parts of the world, including the UK, New Zealand, Argentina, and Chile.
  3. They are extremely successful at adapting to human habitation, so they are a very common bird around cities and towns, now having a population of between 4 and 5 million.
  4. There are 7 subspecies of Canada goose.
  5. They range from 75 to 120 cm in length and have a wingspan of between 127 and 185 cm.
  6. In most bird species, sexual dimorphism is apparent in the differences between male and female bird appearance, but the male and female Canada goose are virtually identical, except for a small difference in weight. Females are smaller.
  7. They spend their summers throughout Canada and the northern United States, but breed in the southern US and northern Mexico.
  8. Canada geese eat mainly plants, but have been known to eat insects and fish. And sometimes they scavenge from garbage cans.
  9. They fly in a v-formation at around 1 km in altitude, but have been known to fly as high as 9 km.
  10. Canada geese are monogamous, mating for life. If one dies, then they can find another mate. They’re very faithful birds.

Let me know in the comments below which facts you didn’t know about or were the most surprised about.

B Is for Bees

The A to Z Challenge continues with the letter B! This time, I talk about bees. It’s springtime, so insects are now coming out. Bees are a very important part of our environment, since they pollinate flowers, and help us grow our plant crops. So, let’s take a look at the video.

Here are the facts, which I mentioned in the video.

  1. There are around 20,000 known species of bee.
  2. The smallest bees are stingless bees that are only 2 mm in length.
  3. The largest bees are the Wallace’s giant bee, a kind of leafcutter bee that grows to 39 mm in length.
  4. Although collection of honey by humans dates back 15,000 years, beekeeping didn’t begin until 4,500 years ago in ancient Egypt.
  5. A bee’s mouthparts are adapted to both chew and suck, having both mandibles and a proboscis.
  6. The explosion of flowering plants 120 million years ago did not coincide with the appearance of bees, which have been around for 100 million years ago, evolving from a type of wasp.
  7. A third of our food supply depends on pollinators, most of which are bees.
  8. Honey isn’t the only thing humans eat. In some countries, the larvae are also eaten.
  9. The decline in bees has been a major worry in recent years, and has been linked to various problems such as pesticides, loss of habitat, and climate change.
  10. It was once said that a bumblebee’s flight was impossible. We now know that the short wing strokes, rotation of the wings, and rapid wing-beats result in sufficient lift. They’re not impossible fliers anymore.

Coming up tomorrow is the letter C. It’s going to be another biological topic. Check back tomorrow!
