Oregon Zoo shares animal X-rays

The Oregon Zoo often has to x-ray its animals for veterinary healthcare purposes, and it recently posted a large collection of these x-rays, providing a unique look under the skin of many furry and scaly creatures. The striking images, which include a chameleon, a toucan, a ball python and the tail of a beaver, can help diagnose veterinary medical conditions more quickly and allow animals to spend less time being kept under anesthesia by their vets.

Key Takeaways:

  • There are plenty of animals out there that need to be looked at like they are humans.
  • Just because there are zoos that do not treat their animals right does not mean this is the case with this zoo.
  • Some people do not realize all that goes into looking after the animals that live within those confinements.

“A zoo in the US state of Oregon has posted images of X-rays of its animals taken during routine health checks.”

Evolution in Perspective

Where did the Sun come from?

In reality, no one knows for sure where the Sun comes from. In fact, no one even knows where the Earth or anything that is truly that ancient comes from. It is all speculation and there are lots of conflicting opinions. However, some have said that the Big Bang Theory is very valid. They feel as if it is a valid explanation as to where the Sun came from. The Sun is so important for the Earth and plays such a crucial role in the life we know.

Key Takeaways:

  • Some people have absolutely no idea where to even start when trying to explain where the Sun came from.
  • The universe is a massive place and it is hard for people to fathom how small Earth is.
  • Scientists from all over the world deliberate and come up with ideas as to where the Sun originated from.

“Originally formed from dying stars’ cast offs, the Sun is the Earth’s energy giver and is destined to keep burning for another five billion years. Professor Bill Chaplin from the University of Birmingham in the UK explains the solar reactions that make the sun shine.”

An Ancient Case of the Plague Could Rewrite History

The remains of a women from thousands of years ago turned up in Sweden. The scientists that discovered her found some really interesting things from the skeletal remains. Sure, her DNA was present within the teeth and bones but one of the most telling things was that there was a bacteria present that had a lot to do with the plague during that time period. Now, scientists are saying that the plague could have originated in Europe based on the findings in the teeth.

Key Takeaways:

  • When the DNA of a Swedish woman who lived 4,900 years ago, it was found that among other things, it contained traces of the plague bacteria, Yersinia pestis.
  • The new find would make scientist believe that rather than originating in Asia, the plague originally originated in Europe.
  • When people die from the plague, their blood contains Yersinia pestis bacteria, which is deposited in the dental pulp. This was the reason for the results.

“The plague is known to have swept through Europe in later times—most infamously as the Black Death during the Middle Ages.”

Mosasaurs 101 | National Geographic

The time periods of where things like Mosasaurs existed is absolutely insane. The amount of information about this time period keeps getting higher and higher as time goes on. Scientists have more access to a lot of different information and as a result, new findings are coming out. Technology is making it easier to be able to tell how old something is and how long it has been around for. That is why National Geographic is so special.

Key Takeaways:

  • Some people believe these kind of stories to be myth and completely fabricated by scientists.
  • In today’s world, there are a lot of things that we already know about the past.
  • National Geographic is an incredible resource to use to learn more about the pre-historic times.

“Mosasaurs were Earth’s last great marine reptiles. Learn about the surprising places they’d hunt, how some species dwarfed even the Tyrannosaurus rex, and how key physical adaptations allowed these reptiles to become a prehistoric apex predator.”

How rare minerals form when meteorites slam into Earth

When meteorites slam into the Earth, there are many implications and things that happen. Scientists do not want this to happen again but in the past, this has definitely happened in the solar system. Space is a crazy place and it is something that not many people can understand. However, when these meteorites are deemed to having slammed into Earth, there are a lot of rare minerals that are formed around the globe. It has been proven to be true.

Key Takeaways:

  • There are so many different theories over what meteorites bring to Earth when they hit.
  • Some people make it their life’s work to know, and to learn, about what is in space.
  • There are plenty of things out there that are impossible to understand when it comes to space.

“Only six prior discoveries of reidite had ever been reported.”

How Your Eyes Make Sense of the World | National Geographic

Everyone sees the world in a different way. It is something that is difficult to explain but everyone has their own goals in life and as a result, they see things differently. When your mind sees something, it warps the perception of it to fit into what you are thinking that it is. That is the beauty of eyes and how they work with our brain. If your brain cannot make something out, it does not matter what your eyes see.

Key Takeaways:

  • The way that you see all of the things that happen on this Earth is different than other people.
  • Everyone has their own way of seeing things and interpreting what they have actually seen.
  • Sight is one of the great phenomenons in the entire world and all species have a way to trigger it.

“In the latest video from Decoder, learn some of the extraordinary science behind how your eyes and brain work together to perceive the world around you.”
