Back in July, scientists were baffled when a mysterious crater appeared seemingly out of nowhere in the Siberian tundra. Seeing as how no simple explanation could be given at the time, people came up with their own theories in an attempt to make sense of the strange phenomenon. As you might imagine, these theories was rather far-fetched and ranged from things such as comets and meteorites all the way to aliens and giant worms erupting from the ground. To make matters even worse, a couple of new Siberian craters have been discovered shortly after, leading some to believe that this is indeed the work of some supernatural or extraterrestrial force. Naturally, researchers managed to came up with a real explanation in the meantime, but as it’s often the case, people would rather believe in science-fiction than in actual science.
Conspiracy theories aside, the reason behind the sudden appearance of the Siberian craters is not difficult to understand and it is the very same reason that most people have stubbornly refused to believe or simply chose to ignore for the longest time. The reason is global warming. I think it’s pretty safe to say that this subject was never truly taken seriously by the majority of people even though there is evidence all around us. Now, new evidence is showing up and it is just as worrying as the fact that sea levels keep rising due to the melting of the polar ice caps. But while that phenomenon doesn’t seem as harmful given that it’s apparently still occurring at a rather slow pace, this new one is downright violent and seems to be happening spontaneously and at random.
But what exactly is causing the Earth to literally explode? Well, researchers say that the unusual hot summers of 2012 and 2013 in the crater area have thawed the permafrost beneath the earth, which in turn caused the frost to collapse and release the large deposits of methane gas trapped within. Methane is a highly flammable gas and ignited because of the heat, thus causing the explosions that left massive craters in Siberia and elsewhere. That’s right, the phenomenon was encountered in other frozen regions as well and scientist believe that it will keep occurring even more often in the years to follow. This is very dangerous to us because high concentrations of methane are about 20 times more damaging to our atmosphere than carbon dioxide. This means global warming could accelerate exponentially in the future if this keeps happening.
As for the craters themselves, they pose little direct danger to human populations at the moment as they seem to be happening in remote, generally uninhabitable areas. However, they can cause serious damage to natural gas pipeline, which coincidentally are quite numerous in the region. Unfortunately there’s not much we can do to stop the craters from occurring given that it’s rather difficult to even predict where the next one will hit. The best thing we can do is try to spread awareness about the fact that global warming is very real and human activity is causing severe climate change. Needless to say, this is very detrimental to us all so hopefully we will be able to come up with a solution to reduce the danger we pose to the planet as well as to ourselves.
Mexican Congress hears UFOs with ‘alien’ bodies
(Reuters). Mexico’s first congressional UFO hearing featured “we are not alone” and alleged non-human remains.
Politicians were shown two artifacts that Mexican journalist and longtime UFO enthusiast Jaime Maussan claimed were extraterrestrial corpses at the Tuesday hearing on FANI.
Maussan said The specimens were unrelated to Earthly life.
Two tiny “bodies,” displayed in cases, have elongated heads and three fingers each. Maussan said they were found in Peru near Nazca Lines in 2017. He estimated their age at 1,000 years using Mexico’s National Autonomous University’s carbon dating.
Mummified children were once found.
Maussan presented such evidence first.
“I think there is a clear demonstration that we are dealing with non-human specimens that are NOT related to any other species in our world and that any scientific institution can investigate it,” Maussan said.
“We are not alone,” he said.
“I can affirm that these bodies have no relation to human beings.”
Thursday, UNAM republished a 2017 statement saying its National Laboratory of Mass Spectrometry with Accelerators (LEMA) only wanted sample ages.
“In no case do we make conclusions about said samples’ origin,” it said.
Congress heard from former Navy pilot Ryan Graves about UAP sightings and the stigma of reporting them.
Sergio Gutierrez, a Morena congressman for President Andres Manuel Lopez Obrador, hoped the hearing would be the first of many in Mexico.
“We are left with reflections, concerns, and how to continue discussing this,” Gutierrez said.
Recent years have seen the U.S. government release UAP data after decades of denial. In recent years, NASA’s first independent UFO panel and the Pentagon have investigated military aviator sightings.
NASA will discuss study results Thursday.
Skeptics slammed Maussan’s Wednesday presentation.
“This could really hurt efforts to take the issue seriously,” tweeted. “Why didn’t they publish it after a scientific paper?”
X-rays, 3-D reconstruction, and DNA analysis were done on the remains, according to Mexican navy Scientific Institute for Health Director Jose de Jesus Zalce Benitez.
New Evidence Modifies Homo sapiens Chronology and Behavior
Earlier this month, researchers published an article outlining new evidence from an excavation in Jebel Irhoud (Morocco) that provides the earliest date yet for the presence of Homo sapiens. A variety of dating methods provide an age of about 315,000 years ago (kya). Prior to this, the earliest securely dated evidence for Homo sapiens were the bones from the Omo Kibish site in Ethiopia dating to about 195 kya.
The decades-long excavation at Jebel Irhoud has uncovered various types of palaeo archaeological data. The skeletal material (e.g. skull, mandible, teeth, humerus, hip bone) shows that there were at least five individuals. The assemblage of stone tools includes examples of the Mousterian industry and the Levallois napping technique. Both of these are closely associated with Neanderthals (Homo neanderthalensis), though are not exclusive to the species. Also, the majority of the tools were made from stone not native to the Jebed Irhoud area. Other recovered evidence includes examples of fire use and animal bones (primarily gazelle) showing signs of hunting and butchering.
A variety of dating techniques helped establish the age of the new assemblage at 315 kya. The research team measured sediment from the different stratigraphic levels for the quantity of radiation present. They used electron spin resonance on bone samples. Finally, the researchers applied thermoluminescence to the stone tools that were in direct association with the bones. Unfortunately, the research team was unable to extract DNA from the bones.
Importance of Evidence
The importance of the evidence is twofold. First, it secures a mature development of Homo sapiens over 100,000 years earlier than previous evidence indicated. The date does not remove the firm placement of Homo sapiens within the Middle Pleistocene and during the Middle Palaeolithic. However, a date of 315 kya does provide overlap with the existence of Homo heidelbergensis. Previous evidence indicated that Homo sapiens developed from Homo heidelbergensis between 300 – 200 kya. The Jebel Irhoud data do not exclude this hypothesis but it means that Homo sapiens must have developed much earlier, probably closer to the nadir of Homo antecessor. It also means that Homo sapiens had much longer contemporaneity with Homo erectus than previously known.
The second important aspect is the location of the finds. Morocco is around 3,400 miles from Ethiopia. The prevailing models of human evolution place the development of Homo sapiens in Ethiopia. This makes sense based on the quantity and age of data recovered from sites in Ethiopia and in East Africa. The location of the new finds, and the fact that the fossils represent developed Homo sapiens, indicate that our ancestors had already moved across the continent in viable population sizes so the broad evolutionary changes that resulted in our species had already occurred.
The Jebel Irhoud evidence does not lessen the importance of East Africa in understanding the development of our species. Rather, it contributes data to provide a richer, more robust picture of hominid development and migrations across Africa and the world. It is quite exciting to imagine what else the excavation will recover to further elucidate the history of hominids and Homo sapiens. What are your thoughts?
Volcanic rocks’ primordial water suggests life might be more common
Life on other planets is considered to be a certainty, and with new evidence of the infinitely intricate details of the universe and their influence on Earth come to light more often as ever, it is undoubtable. However, in a new study involving volcanic rocks and the types of isotopes they contain revealed that life could be more common in the universe than we might have expected.
Volcanic rocks examined by Lydia Hallis and her planetary scientist colleagues revealed that the Earth might have been “born with water”. In the theory they put forward in the latest issue of Science magazine, they argue that the isotopes discovered within volcanic rocks found in Iceland and Baffin Island suggest water had been part of Earth since it first started forming within the protosolar nebula.
Based on the light hydrogen isotope ratio discovered in the volcanic rocks we mentioned earlier, the primordial water within trapped within the rocks came from the protosolar nebula. The researchers demonstrated in their paper last week that the hydrogen isotope ratio in the volcanic rocks was much lighter than ocean water, making it much older. The discovery could hold against the theory that the water on our planet came from numerous water-contaminated asteroid collisions.
The breakthrough came after scientists evaporated volcanic rocks and examined the trapped water in their insides, revealing that Earth has not in fact gathered its water isotopes over the years due to debris from outer space impacting its surface, as previous theories believed. In fact, the primordial water from within the volcanic rocks of Iceland might be straight out of the Protosolar Nebula – or the gas and hydrogen molecular clouds that eventually became the Solar System.
The theory suggests that if the Solar System’s nebular history of formation is considered, then we should be able to find many different solar systems with planets like Earth orbiting around. These planets could have actually harbored the same primordial water at one point in time in the past few billion years, and if their geology was as fortunate as Earth’s, they might have evolved in the same way our own planet has. Water may signify the presence of biological life, thus the chances of finding planets similar to Earth might be slightly higher. The theory cannot be considered definite proof, of course, but it does propose an interesting idea.
If planets within solar systems are formed from the same materials as the primordial protosolar nebula, and are capable of retaining water in a similar manner to Earth, the possibility of finding life closer to home is greatly increased. However, that doesn’t mean that we might be closer to intelligence. You might have heard theories about inferior forms of life being closer to us than we had ever thought – on Mars, for instance. In the future, we might discover primordial water on the Red Planet.
The volcanic rocks that the scientists base their theory on can now be considered as the first evidence of primordial water on Earth. If you want to get in on the science behind analyzing these unique volcanic rocks, you can read the full study in Science magazine. The discovery is significant and brings us one step closer to identifying the first planet, aside from Earth, harboring biological life.
