Study predicts first human-alien encounter in around 1,500 years

Study predicts first human-alien encounter in around 1,500 years

While many people believe that NASA missions already have had contact with Aliens, there hasn't been any solid proof till date. Human race gets excited about any topic related to aliens and astronomers have not ruled out the chances of alien life at other planets in the Universe. NASA and other space agencies have been trying to find out planets that can support conditions for existence of life.

Climate change pushed megafauna into extinction: research

Climate change pushed megafauna into extinction: research

Large mammals like sloths, saber-toothed cats, giant bears and mammoths lived in South America and went extinct around 12,000 years ago. Evolutionary biologists and ecologists believe that blame two possible culprits for the disappearance of those gigantic mammals.

One possibility is that those ancient large mammals went extinct because of the peopling of the Americas. Supporters of this theory believe that humans hunted the big animals to extinction.

Monumental platform uncovered in ancient city of Petra in Jordan

Monumental platform uncovered in ancient city of Petra in Jordan

Using Google Earth, satellite imagery, ground work and photography, researchers have uncovered a large new monumental platform in the Petra World Heritage site in Jordan. The large rectangular platform measures around184 feet by 160 feet.

The researchers said that within this platform, there is another, smaller platform. The site is present just half a mile from the center of the 2,500-year-old city. The study researchers Sarah Parcak and Christopher Tuttle said that the platforms also have a small building.

Archeologists discovering hidden chambers of pyramids using new technology

Archeologists discovering hidden chambers of pyramids using new technology

The pyramids, one of humans’ most visible architectural achievements, have been perplexing archaeologists for decades because many parts or chambers of these ancient structures have remained invisible. But, particle scanners are expected to help archeologists expose those secret chambers.

University of Rochester researcher talks about possibility of alien civilizations

A new study has focused on quite an old question as to whether humans are alone in the universe. The new study has provided a simplified version of astronomer Frank Drake’s famous Drake equation first published in 1961. The equation highlights variables vital for a technologically inclined civilization.

North America's First Monkeys Could Have Rafted Over to Panama on Vegetation: Research

North America's First Monkeys Could Have Rafted Over to Panama on Vegetation: Research

New fossils of monkeys unearthed in Panama may shed light on North America's first monkey. Previously, it was believed that monkey ancestors migrated to North America from South America no earlier than four million years ago, but a new analysis pushes the tale of ancient migration to 21 million years ago.

Before the recent discovery of seven monkey teeth in Panama, historians believed that monkey ancestors first landed on the North American soil some four million years ago when both the continents became one.

Wiltshire Farmhouse Owner Accidentally finds Remains of Roman Villa

A Wiltshire resident accidentally found remains of Roman villa in his garden when he was laying electric cables. Now, it is believed that the discovery could be one of the largest such Roman villas in Britain.

According to the land owner, Luke Irwin, he unearthed the ancient villa when he was working at his farmhouse in Tisbury so that his children could play table tennis. The villa may date back around 1,400 years and may have been home to an emperor.

Infections carried by ancient humans from Africa probably contributed to demise of Neanderthals

Infections carried by ancient humans from Africa probably contributed to demise of Neanderthals

A latest study has suggested that ancient humans, who had moved out of Africa, could have infected Neanderthals with herpes. There have been a number of theories regarding demise of Neanderthals. According to the researchers of the new study, the infections brought by humans from Africa could have led to that downfall.

They have identified many types of infections that probably had made the species of hominins sick. The infections include tapeworm infection, tuberculosis, stomach ulcers, and the specifically striking disease herpes.

Researchers carry out first in-depth genetic analysis of Neanderthal Y chromosome

Researchers carry out first in-depth genetic analysis of Neanderthal Y chromosome

A research paper published in the American Journal of Human Genetics has unveiled new facts about the relationship between Neanderthals and modern humans and genetic factors that have kept two lineages separate. Earlier research has indicated that modern humans and Neanderthals may have interbred at different times and at different regions.

In the study, researchers have completed the first in-depth genetic analysis of a Neanderthal Y chromosome. The Y chromosome was the main factor that was yet to be assessed from the Neanderthal genome.

Incompatibilities in DNA of Neanderthals and modern humans probably limited impact of interbreeding between them

PENDING-Incompatibilities in DNA of Neanderthals and modern humans probably limited impact of interbreeding between them

This might be the case that incompatibilities in the DNA of Neanderthals and modern humans restricted the impact of interbreeding between these two groups. Now, it is commonly known that a number of modern humans have 4% Neanderthal DNA.

However, a latest analysis of the Neanderthal Y chromosome, which is the genes’ package passed down from fathers to sons, has demonstrated that it is absent in modern populations.
