What is the mysterious Yellow Brick Road off the coast of Hawaii?

An underwater expedition to explore the Papahanaumokuakea Marine Reserve area off the coast of Hawaii has had some of the researchers excited about viewing the images transmitted by the submersible. In particular, they woke up with an image of a road that resembled a yellow brick road.

The problem was that the formation was about 1,000 meters deep, and there was no geological evidence that the area had been on the surface in the recent past for anyone to build roads there. Apparently, even among those directly involved in this, there were rumors that Atlantis had just been discovered or who knows what traces of prehistoric civilizations.

Unfortunately for fans of sensationalism, the images transmitted by the Nautilus submersible are only a geological formation. A special, but nevertheless geological formation. In short, it is volcanic rock that has been fractured at a 90 degree angle due to the rapid heating and rapid cooling of volcanic activity in the area.

And those who dreamed of discovering Atlantis will not be lucky, maybe next time.

We have the first clear evidence that dinosaurs ate mammals

What would it be like to have a dinosaur skeleton that was studied for more than 20 years and noticed that all this time the animal had a fifth leg? If we set aside the fact that pentapods do not exist, then in this case the fifth leg was not even where it should have been, but in the chest of the dinosaur.

After briefly toying with the idea of ​​professional repurposing, researchers at MgGill University in Montreal enlisted the help of an international team of specialists from the UK, US, Canada and China, and thank goodness they succeeded. Or legs.

It turns out that the microraptor in question, a feathered dinosaur about the size of a cat, died when it bit the mammal’s leg, or at least shortly thereafter. Thus, his last meal petrified along with the predator.

The discovery is particularly important from several perspectives. First, we all breathe a sigh of relief, there really were no five-legged dinosaurs. Second, we have the first clear evidence that dinosaurs ate mammals, and it’s not a big surprise. We can finally have a clear picture of what microraptors meant in the food chain 120 million years ago. And they were just causing chaos there. A microraptor would be cute with its feathers, fangs and fangs, just good to squish, but it would kill almost every small animal near a person’s house if you didn’t keep an eye on it. Do you really know something? That meteorite benefited them!

Dolphins are developing before our eyes

Dolphins are one of the most studied animals in the world. And yet, marine biologists couldn’t seem to see what was right under their noses. In particular, the fact that dolphins are evolving right before our eyes and that we obviously need to create new taxonomic subspecies.

In a case recently presented in the Journal of Mammalian Evolution, several researchers at the University of Miami mention Tursiops truncatus, or the bottlenose dolphin. A species with a wide distribution, but which seems likely to have a few more subspecies than we expected. And the truth is that only the Black Sea dolphin (T. ponticus) and the Brazilian dolphin (T. Gephyreus) have been cataloged as different subspecies. Otherwise, they are all in a heap.

That’s where the aforementioned researchers come in, who noticed that dolphins in the Galapagos Islands and off the coast of northern California don’t really look like dolphins in southern California or off the coast of Japan. In fact, the former not only have a smaller skull than the others, but their body sizes are also smaller. Therefore, it was proposed to assign them to the subspecies Tursiops truncatus nuuanu.

The aforementioned researchers also claim that dolphins, extremely versatile creatures, have adapted to live near the coasts of all continents. Encountering different environments, they obviously also took different forms. And this seems to be just one step in a continuous evolutionary process.

Eat pickles for dreamy breath!

Probiotic bacteria found in fermented foods could make a huge contribution to eliminating bad breath, some Chinese researchers report in the specialized journal BMJ Open. Lactobacillus salivarius, Lactobacillus reuteri, Streptococcus salivarius, Weissella cibaria are just a few that, taken in supplement form, will give you spring breath while you talk.

The main causes of bad breath are bacteria in the mouth, leftover food, and poor hygiene. Until now, teeth brushing, tongue brushing, mouth rinsing, and other similar methods have been used to eliminate bad breath. You didn’t even know that probiotic bacteria do their job just as well.

They prevent the breakdown of amino acids and proteins by anaerobic bacteria in the mouth. By default, he has nothing left to smell bad. Please note that the researchers also explain that in the case of wounds or more serious illnesses, you should not treat yourself with vinegar straight from the pickle jar.

But otherwise, here you can combine the useful with the pleasant. By the way, try eating a few pickles before going to a meeting or an important meeting. You will become a sensation, as the Chinese say.
