Scientists Discover Ancient Viruses In Tibetan Glacier

  Scientists Discover Ancient Viruses In Tibetan Glacier Per a new research, scientists discovered 28 new types of ancient viruses that have been trapped inside a Tibetan ice glacier for 15,000 years.Recently, however, scientists broke up the millennia-long party by taking a look at the Tibetan glacier’s two ice cores, revealing around 28 new virus groups that we have never seen before.

Canadian scientists have discovered a fragment of an ancient continent , suggesting that it was 10% larger than previously thought. "Finding these ' lost ' pieces is like finding a missing piece of a puzzle," Ms Kopylova is quoted as saying in an article published by the University of British

Scientists have uncovered a splintered remnant of Earth's continental crust from millions of years ago, embedded in the isolated wilderness of northern Canada.

Baffin Island, located in between the Canadian mainland and Greenland, is a vast Arctic expanse covering over 500,000 square kilometres (almost 200,000 square miles), making it the fifth largest island in the world.

While the island comprises part of the newest recognised territory in Canada – Nunavut, formally established in 1999 – a new discovery shows this ancient landmass has undisclosed ties that stretch backwards in time so far, they actually emanate from a distant geologic eon.

Who really discovered Antarctica? Depends who you ask.

  Who really discovered Antarctica? Depends who you ask. In 1820, two rival expeditions set out to discover Antarctica—but only one could be first.By the early 19th century, explorers had been on the hunt for a massive southern continent they called Terra Australis Incognita (“unknown southern land”). This vast landmass, it was thought, would “balance out” the land in the Northern Hemisphere. But early attempts to find the continent had flopped. Captain James Cook had spent three years looking for it during his second voyage from 1772-1775. The expedition took Cook and his men into the Antarctic Circle, but the explorer eventually called it quits after failing to find the continent.

Several smaller lost continents , called microcontinents, have also recently been discovered submerged in the Perhaps the best known example of a lost continent is Zealandia. During a 2011 expedition, we discovered two lost continental fragments more than 1,000km west of Perth.

Diamond rock samples that have been uncovered from deep underground in Baffin Island, Canada , form part of the puzzle of Earth's ancient continent Geologists find a lost fragment of an ancient continent filled with diamonds that formed part of Earth's continental crust 2.7 billion years ago in

While analysing igneous rock samples recovered from diamond exploration drilling in the Chidliak Kimberlite Province at the southern stretches of Baffin Island, researchers identified a mineral signature in the rock they had never expected to find.

"Kimberlites are subterranean rockets that pick up passengers on their way to the surface," explains geologist Maya Kopylova from the University of British Columbia.

"The passengers are solid chunks of wall rocks that carry a wealth of details on conditions far beneath the surface of our planet over time."

In this case, those passengers had completed a very long journey. The team says kimberlite rocks like this, formed at depths below 150 kilometres (93 miles), are driven to the surface by both geological and chemical forces.

Sarcophagus dedicated to sky god among latest ancient Egypt trove

  Sarcophagus dedicated to sky god among latest ancient Egypt trove Egypt's antiquities ministry on Thursday unveiled the tombs of ancient high priests and a sarcophagus dedicated to the sky god Horus at an archaeological site in Minya governorate. The shared tombs were dedicated to high priests of the god Djehuty and senior officials, from the Late Period around 3,000 years ago, the ministry said. They were from the 15th nome, an ancient Egyptian territorial division ruled over by a provincial governor.One of the stone sarcophagi was dedicated to the god Horus, the son of Isis and Osiris, and features a depiction of the goddess Nut spreading her wings.

Scientists say they have discovered a 3 billion year piece of crust in the Indian Ocean under the island of Mauritius which “It’s not Atlantis, but there is a small fragment of continent . This may even be part of what is called Mauritia, an ancient “undiscovered” microcontinent, that broke off after India

Diamond-encrusted rock samples discovered on a Canadian island come from an ancient continent that was probably 10 per cent larger than has always been The fragments of the North Atlantic Craton – a vast land mass which stretched from Europe to North America – were found on Baffin Island.

In terms of the geological component, their emergence underneath modern-day Baffin Island represents the end of a colossal dispersal that occurred approximately 150 million years ago, during rifting of the continental plate of the North Atlantic Craton (NAC).

This NAC refers to chunks of lithospheric rock that date back billions of years ago to the Archean Eon, representing some of the best exposures of Earth's earliest continental crust.

Rifted into fragments millions of years ago, NAC has been exposed in Scotland, Labrador, and Greenland, but researchers weren't expecting to find it in Baffin Island's Hall Peninsula.

"The mineral composition of other portions of the North Atlantic Craton is so unique there was no mistaking it," says Kopylova.

"It was easy to tie the pieces together. Adjacent ancient cratons in Northern Canada – in Northern Quebec, Northern Ontario and in Nunavut – have completely different mineralogies."

Researchers Have Uncovered A New Species Of Dinosaur Named 'Reaper Of Death'

  Researchers Have Uncovered A New Species Of Dinosaur Named 'Reaper Of Death' The 'Reaper of Death' is a sub species of tyrannosaur that has recently been discovered in Alberta, Canada. The tyrannosaur is the first new species of the sort to be discovered in 50 years.Dr François Therrien, Curator of Dinosaur Palaeoecology at the Royal Tyrrell Museum states:

Scientists have discovered fragments of an ancient continent that lies buried beneath the island nation. The research could herald the further discovery of fragments of old continents , according to experts. Several pieces of ancient continents have been discovered off the coast of Western

Fragments of an ancient continent are buried beneath the floor of the Indian Ocean, a study suggests. Researchers have found evidence for a The zircon dated to between 1,970 and 600 million years ago, and the team concluded that they were remnants of ancient land that had been dragged

To reach their findings, the team used a number of analytical techniques – including petrography, mineralogy, and thermobarometry – to study 120 rock samples, called xenoliths, taken from the kimberlite province.

The results showed the Chidliak mantle "strikingly resembles" the NAC rocks from West Greenland in terms of their bulk composition and mineral chemistry, while showing numerous contrasts with markers from other cratons.

"We conclude that the Chidliak mantle demonstrates an affinity with only one adjacent block of cratonic mantle, the NAC," the authors explain in their paper.

"We interpret this similarity as indicating the former structural coherence of the cratonic lithosphere of the Hall Peninsula Block and the NAC craton prior to subsequent rifting into separate continental fragments."

The new findings mean we've discovered about 10 percent more of the known expanse of the NAC – a pretty sizeable chunk of this incredibly ancient crust. And thanks to newer mantle modelling techniques, we can also envisage the shape of some of Earth's earliest known rock formations at much greater depths than ever before.

"With these samples we're able to reconstruct the shapes of ancient continents based on deeper, mantle rocks," says Kopylova.

"We can now understand and map not only the uppermost skinny layer of Earth that makes up one percent of the planet's volume, but our knowledge is literally and symbolically deeper."

Superconductivity Has Been Discovered in Meteorites For The First Time .
Scientists have found naturally occurring superconducting materials in extraterrestrial objects for the first time, discovering superconductive grains embedded inside two distinct meteorites that crash-landed on Earth. The discovery is just the latest to show that meteorites are much more than space debris that falls out of the sky. Recent investigations have turned up meteorite-borne deliveries of possible extraterrestrial proteins, minerals we've never encountered, and materials older than the Solar System itself. But we've never seen something quite like this before.
