New research from the laboratory of Harvard Medical School has suggested that microbes may have lived underground for over a billion years.
Dating from the Mesolithic age, this research was led by Professor Salvatore De Laurentiis and his team. The study involved the analysis of cores from nine caves in southwestern Italy which had yielded floras consistent with a terrestrial environment. Other areas of Europe and North America also yielded signs of microbial activity in cavities drilled from cliff sides, slopes, and other landscapes which suggest that these organisms have occupied the surfaces of these landscapes for many billions of years.
Is it possible that microbes may have lived underground for over a billion years?
This would make the most sense if you believe the Earth is only a few million years old. If you think the Earth is much older, you might be surprised to learn that microbes have been living in the limestone and other rock surfaces of our planet for several million years. It seems amazing that microbes would have stayed underground for this long without being affected by modern society made pollutants.
New species of human ancestor were previously detected from fossils.
These fossils have been excavated from two sites in Dmanisi, Georgia, and South Africa. These recent finds are considered to be the first evidence of a new species of human ancestor that lives today. According to the research paper published by Zimov et al. from the University of Nairobi, Kenya; fossils from south Africa reveal diverse features of early hominids, and fossils from China and Europe imply that hominids branched into three subspecies or species.
Dating methods such as molecular clock analysis, stable isotope ratios, and morphological mosaic analysis were used to identify these fossils. The two fossils discovered were a H. erectus and a H. sapiens. In order to date these fossils the fossils were dated using a radioactive source. The oldest specimen was dated at about 48 million years ago.
The study also revealed the oldest evidence of modern human activities, which is dated at four years ago. During the last million years ago, the ice age appeared, and large glaciers covered the landscape. These large glaciers contributed to the massive sea level rise during the last million years. This sea level rise caused sea levels to rise, which resulted in massive coastal erosion and retreats of various human ancestor species.
Have you ever heard of a 2 billion year old traces of life locked inside primeval red ruby?
The news is out there. The latest research has found traces of ancient inhabitants of Australia and Africa, which show that these people colonized this land much before the current era. These evidences have been collected from within the interior of these rocks by the scientists. These red rinds also show evidence of animal collagen and spores, which is confirmed to be authentic.
Some scientists are claiming that the fossils are older than the age of the Earth. They also say that they contain DNA that is older still. If these are true then it means that before the start of the universe, we have already colonized this planet. If they are correct then there are millions of older beings in this primeval solar system, which have left their mark on this pale blue dot.
Have you ever heard about the latest discovery in physics?
In the news, there are a lot of stories about something called the ‘unbreakable particle’. Is this real and how come there are people who are talking about it? If so, what is this thing? Let us find out.
First of all, the name itself is quite ambiguous as well as the topic on which the particle is being talked about. If one were to talk about a black hole, it would be one of them, but if one were to talk about a concept that is associated with time, then that would be quantum mechanics or just pure time. Theoretically, one could imagine some kind of particle that has the potential to withstand time and space. It would be one of the most fascinating concepts that people will definitely try to understand in the near future.
If one were to take just one simple step forward, we might get closer to answering the question, “what is the impossible particle?” It would be thanks to the experiments of scientists all over the world, and especially to those who have worked on the Large Hadron Collider (LHC). These experiments took place last year and the results are still being analyzed.
Stephen Hawking might be known as one of the most popular and influential scientists of all time.
His scientific works have inspired many people around the world. He has become a phenomenon by offering some amazing discoveries and theories, most of which have been proved true. If there is someone important enough in the world, then surely they have had a similar experience and can vouch for his greatness.
While many might be content to listen to what the great man has to say on the latest topics, some may not be aware of his greatest insights. One of the most quoted instances is his famous quote from the movie, “A Brief History of Time” where he said, “We cannot learn science or engineering, not by studying the phenomena, but by trying to understand their laws.” That is quite an astounding statement coming from one of the giants of the modern era. But, what did he mean by this?
According to him time is a way of measuring a thing. One can measure the speed of light, its temperature or any other number of things, based on the time that it took to do something. Similarly, the universe also took time to develop, from the very first moment of the Big Bang to the present. Therefore, we cannot say that the world itself has developed, because time does not stand still, neither does the universe.
