This handout image received from Gem Diamonds via the Celicourt PR agency on January 15, 2018 shows a 910 carat diamond discovered at the Letseng mine in Lesotho. A diamond thought to be the fifth largest of gem quality ever found has been discovered in Lesotho, miner Gem Diamonds said on January 15, 2018 and could be worth as much as $40 million. The company unearthed the D-colour stone at the Letseng mine in the landlocked southern African country and described the 910-carat find as of "exceptional quality". A diamond thought to be the fifth largest of gem quality ever found has been discovered in Lesotho, miner Gem Diamonds said Monday, and could be worth as much as $40 million. The company unearthed the D-colour stone at the Letseng mine in the landlocked southern African country and described the 910-carat find as of "exceptional quality". Since Gem Diamonds acquired Letseng in 2006, the mine has produced some of the world's most remarkable diamonds, including the 603 carat Lesotho Promise," Gem Diamonds chief executive Clifford Elphick said in a statement. However, this exceptional top quality diamond is the largest to be mined to date. This is a landmark discovery. Ben Davis, a mining analyst at Liberum Capital, speculated in a research note to investors that the diamond could be worth as much as $40 million (33 million euros). Gem Diamonds shares in London were up 14 percent from the market open to £0. 92 a piece.

1000-year-old royal palace discovered in China

  • Published in World

The Temple of Heavenly Peace in Beijing, the oldest and one of the only surviving remnants of Beijing's Liao Dynasty capital. Archaeologists have discovered the ruins of an ancient palace that served as the summer retreat for the elite members of the Liao Dynasty. To escape the oppressive heat, each year from mid-April to mid-July the Liao emperors would move the royal family, along with palace officials, into the mountains of what is now China's Inner Mongolia Autonomous Region, according to Chinese state news agency Xinhua.

Archaeologists discovered more than 100 structural components at the site in Duolun County, including glazed tiles, pottery and copper nails, according to Xinhuanet. They recorded the foundations of 12 buildings—more than 2,500 square feet in total. e Zhiyong, a researcher with the Inner Mongolia Autonomous Region Institute of Archaeology, said that artifacts excavated at the site appear to date the palace to the mid-Liao Dynasty, according to Xinhua.

The palace's discovery should give archaeologists new insights into both the architecture and cultural customs of the Liao Dynasty, Ge told Xinhua. Large-scale excavations are expected to begin at the site.

The Liao Dynasty rose from the Khitan, the nomadic people of what corresponds to modern-day Mongolia and parts of northern China, Russia and Korea. The dynasty came to power in either 907 A. D. or, depending on historical interpretation of what constitutes the dynasty's early days, in 916 A. D. when Abaoji officially declared himself as ruler. The dynasty excelled in art, music and poetry, according to Ancient Origins. In 1125, the Liao Dynasty fell to the rising Jin Dynasty, which would reign for more than a century afterwards.

The Liao Dynasty style of expansion served as an early template for the later Mongol conquerors. Though the dynasty began with no written language for their "proto-Mongol" spoken dialect, its members developed two kinds of written scripts which, despite containing similarities to Chinese characters, have yet to be fully deciphered, according to the non-profit Asia Society.

They expanded aggressively, but to retain the "purity" of the Imperial family, ruling emperors couldn't marry from any foreign populations the Khitan conquered, according to Asia Society. However, the women who were part of the Imperial family may have had more political influence than their Chinese counterparts at the time. At least three Liao empresses have been historically documented as wielding "tremendous power" and dictating court policies, according to Asia Society.

The dynasty was the first foreign one to merge its original nomadic structure of conquest and cultural assimilation with prevailing Chinese style of government at the time, according to Asia Society, a strategy later emulated by the Mongol hordes—who came to power after they conquered the Jin dynasty.

Supercomputer provides black hole breakthrough

Using supercomputer simulations, astronomers have discovered more about how black holes interact with space-time.

Black holes are regions of space-time whose gravitational effects are so strong that even electromagnetic radiation such as light cannot escape from inside of them.

As such they are incredibly difficult to study, although a collaboration between researchers from Northwestern University and the University of Amsterdam in the Netherlands has managed just that.

They were examining the "relativistic jets" from black holes, the material that actually does manage to escape from them - one of the most mysterious phenomena in modern astronomy.

As explained by Northwestern University: "Similar to how water in a bathtub forms a whirlpool as it goes down a drain, the gas and magnetic fields that feed a supermassive black hole swirl to form a rotating disk - a tangled spaghetti of magnetic field lines mixed into a broth of hot gas.

As the black hole consumes this astrophysical soup, it gobbles up the broth but leaves the magnetic spaghetti dangling out of its mouth. This makes the black hole into a kind of launching pad from which energy, in the form of relativistic jets, shoots from the web of twisted magnetic spaghetti.

The scientists ran complicated simulations on one of the world's most powerful supercomputers and discovered that these relativistic jets actually changed direction as a result of space-time itself being dragged into the rotation of the black hole.

Understanding how rotating black holes drag the space-time around them and how this process affects what we see through the telescopes remains a crucial, difficult-to-crack puzzle," according to one of the researchers.

Alexander Tchekhovskoy, assistant professor of physics and astronomy at Northwestern's Weinberg College of Arts and Sciences, said: "Fortunately, the breakthroughs in code development and leaps in supercomputer architecture are bringing us ever closer to finding the answers.

The researchers discovered that where previously simulations considered the disks and the axis of the black hole's rotation were aligned, in reality they are unlikely to be parallel.

The study confirmed that these tilted disks, which are likely to include the disk of the black hole at the centre of our own galaxy the Milky Way, change direction, much like a spinning top, causing the direction of the relativistic jets to change too.

The high resolution allowed us, for the first time, to ensure that small-scale turbulent disk motions are accurately captured in our models," Mr Tchekhovskoy said.

To the researcher's surprise the motions turned out to be so strong that they caused the disk to fatten up and the direction changing to stop.

The results of their research are now being applied to interpreting the observations of the Event Horizon Telescope examining the black hole at the centre of the Milky Way.

Underground city discovered beneath a house

These stunning images show the underground 18-storey city discovered by chance by a man renovating his home.

In 1963, a Turkish dad knocked down a wall in his basement, revealing a secret room which led to an underground tunnel that took him to the ancient city of Derinkuyu.

Photos of the preserved city document how 20,000 people - including livestock and entire food supplies - could have lived 85m beneath the earth.

Thought to have been created during the Byzantine era in 780-1180AD, the network of kitchens, stables, churches, tombs, wells, communal rooms and schools was most likely used as a bunker to protect inhabitants from the Arab–Byzantine wars.

During this time, cave-like chapels and Greek inscriptions were added to the ancient city , and about 600 entrances allowed people to come and go.

Heavy stone doors could close Derinkuyu from the inside in order to fend off intruders, and each storey could be shut off individually.

Amazingly, Derinkuyu isn't the only one of its kind - though it's in the running to be one of the largest underground cities.

The hidden community, in the region of Cappadocia, is connected to other subterranean cities by tunnels stretching several miles.

Only about half of Derinkuyu is accessible, but the site has proved to be a popular tourist attraction.

The historical region in Central Anatolia also attracts visitors with its incredible geological, historic, and cultural features, including rock formations and spires known as 'fairy chimneys'.

Ancient shark species named after legendary Alabama coach

  • Published in World

A megaoldon tooth (center) and three Bryant shark teeth (right. Imagine a great white shark as long as a bowling lane, with teeth that could grow up to the size of your hand. Does this sound like the monster in a B-movie? Well, yes, megalodon is the star of several low-budget thrillers, but it was also a real animal. From 23 million to 2. 6 million years ago, the largest shark that ever lived ruled the warm waters of the world.

Now, scientists have discovered a dinosaur-era shark may have been an even earlier ancestor of megalodon, illustrating the evolution of one of the most fearsome creatures to swim the earth.

Paleontologists have been collecting fossilized ancient shark teeth in Alabama for decades. or the Bryant shark.

Researchers from the University of Alabama and the McWane Science Center, also in Alabama, identified 33 teeth belonging to this species. were found between 1980 and 2011 in the Black Belt region of Alabama. This 240-mile region reaches from the northwest corner of the state into the center and provides a snapshot of the Upper Cretaceous period, which stretched from 100. 5 to 66 million years ago, that is "nearly perfect," the study authors write. C. lived about 83 million years ago and gave rise to a variety of ancient shark species, including megalodon.

Paleontologists almost never find shark fossils that represent anything other than the teeth of the animals. That’s because sharks have bones only in their mouths; their “skeletons” are made of cartilage, a soft tissue that rarely leaves fossil remains. rn sharks give us the best clues about how their extinct ancestors may have looked, which is why artists and filmmakers often portray megalodon as a great white shark, but scaled up.

The Bryant shark was an early member of a group of “mega-tooth” sharks, most of which went extinct at the same time as the non-bird dinosaurs 66 million years ago. e teeth on this shark were much smaller than those of megalodon; the biggest Bryant shark tooth discovered so far is only an inch long. That also means that its body probably was about 15 feet long.

sharks in the megalodon line, "grow to enormous sizes. This new study adds to our understanding of the ancient, giant creatures that once swam the saltwater seas of what is now Alabama.

The researchers named the shark after football player Paul "Bear" Bryant, who coached the University of Alabama's football team for 25 years.

'Have dirt on Nawaz’s family'

A combative Pakistan Tehreek-e-Insaf (PTI) party chief Imran Khan put former Pakistan Prime Minister Nawaz Sharif and his family as well as media mogul Mir Shakeel ur Rehman in his crosshairs as he broke his silence on the matter of his love life becoming an obsession in his country. For 3 days I have been wondering have I looted a bank; or money laundered bns [billions] in nation's wealth; or ordered a model-town-like killing spree; or revealed state secrets to India? Khan wondered in a six-part tweetstorm.

I have done none of these but discovered I have committed a bigger crime: wanting to get married," Khan tweeted before going on to criticise Nawaz Sharif and Mir Shakeel ur Rehman for running a "vicious, gutter media campaign". Khan said that he has known the Nawaz Sharif for 40 years and that he "know(s) all their sordid personal lives but would never stoop to the level of exposing these sordid details.

When we found out we were brothers, we were so excited,” Walter Macfarlane, 74, told InsideEdition. om.

Macfarlane and Alan Robinson, 72, who were born in Hawaii 15 months apart, have been friends for 60 years after meeting on the football team in middle school.

He was an athlete,” Robinson said. He was older and he was a very handsome, honest kind of guy, so I looked up to him and respected him.

Macfarlane grew up believing his grandmother was his mother, and when he turned 18, he discovered the woman he believed to be his sister was his actual birth mother.

Robinson, who grew up with a different set of parents, said he knew from the very beginning he was adopted.

and submitted the results.

Macfarlane did his own DNA test last year with hopes of finding his biological father.

Instead, McFarland discovered he and his best friend shared a birth mother.

60-something years and we didn’t realize,” Robinson said. couldn’t contain myself, the emotions were overwhelming.

They said their birth mother died more than a decade ago, but are now hopeful their children and grandchildren are ready to begin their lives as one big family.

I think my adopted parents knew and took that secret to their graves,” Robinson said.
