Ball’s Pyramid — Last Home to the Lord Howe Island Stick Insect

Atlas Obscura showcases Ball’s Pyramid in one of their newest videos. Ball’s Pyramid juts out of the Pacific Ocean 1,844 ft into the air and is actually the remnant of “a shield volcano and caldera that formed about 6.4 million years ago.”

What makes this island particularly special is that it’s home to the last remaining wild population of the Lord Howe Island Stick Insect. Watch the video for more information.

Sharks Discovered Inside the Underwater Volcano, Kavachi

Recently, scientists discovered sharks swimming in the underwater volcano, Kavachi. This raises some interesting questions for scientists. Mainly, because the volcano is active, how do the sharks know when it will erupt?

Via the National Geographic YouTube description:

A real life sharkcano? Ocean engineer Brennan Phillips led a team to the remote Solomon Islands in search of hydrothermal activity. They found plenty of activity—including sharks in a submarine volcano. The main peak of the volcano, called Kavachi, was not erupting during their expedition, so they were able to drop instruments, including a deep-sea camera, into the crater. The footage revealed hammerheads and silky sharks living inside, seemingly unaffected by the hostile temperatures and acidity.

Phillips said, “You never know what you’re going to find. Especially when you are working deep underwater. The deeper you go, the stranger it gets.” They knew they would see interesting geology but weren’t sure about the biology.

In the Beginning there were Simple Chemicals – New Evidence on the Origins of Life

Via Phys.org:

In the beginning, there were simple chemicals. And they produced amino acids that eventually became the proteins necessary to create single cells. And the single cells became plants and animals. Recent research is revealing how the primordial soup created the amino acid building blocks, and there is widespread scientific consensus on the evolution from the first cell into plants and animals. But it’s still a mystery how the building blocks were first assembled into the proteins that formed the machinery of all cells. Now, two long-time University of North Carolina scientists – Richard Wolfenden, PhD, and Charles Carter, PhD – have shed new light on the transition from building blocks into life some 4 billion years ago.

“Our work shows that the close linkage between the of amino acids, the , and protein folding was likely essential from the beginning, long before large, sophisticated molecules arrived on the scene,” said Carter, professor of biochemistry and biophysics at the UNC School of Medicine.

Evidence of interpersonal violence has been documented previously in Pleistocene members of the genus Homo, but only very rarely has this been posited as the possible manner of death.

The tools are 3.3 million years old.

Ian Johnston via The Independent:

The world’s oldest tools – made by ancestors of modern humans some 3.3 million years ago – have been found in Kenya.

Stones had been deliberately “knapped” or flaked to make a sharp cutting edge, researchers said, according to Sciencemagazine.

They are about 700,000 years older than the previous record holder and are likely to have been made by Australopithecus, an ape-like ancestor of Homo sapiens, or another species, Kenyanthropus.

Archaeologist Sonia Harmand, of New York’s Stony Brook University, told the annual meeting of the US Paleoanthropology Society: “The artefacts were clearly knapped and not the result of accidental fracture of rocks.”

About 150 flakes, the stones they were taken from and anvils on which the stones were placed while they were struck were found near Lake Turkana in Kenya.

Arabic Engraved Ring Found in Viking Grave

Viking-Islamic-Ring

A ring found in a 9th century grave in Birka, Sweden (home to a Viking trading center) suggests that Vikings had contact with Islamic civilizations. The silver ring, found in a Viking woman’s grave, has a beautiful violet-colored glass gem engraved with “To Allah” or “For Allah” in Arabic. “Ancient texts mention contact between Scandinavians and members of Islamic civilization, but such archaeological evidence is rare.”

After I “Discovered” an Abandoned Town and My Film Went Viral

opmtbc8rmsramv6r6lus

It was 4:47pm in San Diego on October 1, 2014. A YouTube user named trixxie62 subscribed to my channel, sending an email notification to my inbox. This triggered my phone’s “new email” ringtone. Several minutes later another one came in. Then another. After that I was receiving a new subscriber every 1-2 minutes, far exceeding the usual 1-3 per week.

Upon checking around I found that Roadtrippers.com had included my film in a story on their website and social media pages. The story was receiving more Facebook Likes and Comments than any other Roadtrippers story in weeks. It seemed like an exciting moment. But things were about to take an unexpected turn.

Very often you can read stories about people who were perceived to have said something dumb, hateful or untrue, then they pay for it by being called out on social media and in the news. While I can’t particularly speak to never saying anything “dumb,” I can confirm that I did not say anything hateful or untrue.… Read the rest

Mysterious ‘Ghost’ Ship Rediscovered Near Hawaii

via Live Science:

A “ghost ship” that has been lost beneath the waves for more than 60 years has been discovered nearly a half-mile below the ocean surface off the Hawaiian island of Oahu.

A small submersible vehicle came upon the shipwreck last year, researchers at the University of Hawaii announced today (Dec. 5). Despite being torpedoed after World War II, many parts of the ship, including the ship’s wheel, are still in their original locations.

“The upper deck structures from the bow to the stern were well-preserved and showed no sign of torpedo damage,” Terry Kerby, a submersible pilot with the university’s Hawai’i Undersea Research Laboratory, said in a statement. [Shipwrecks Gallery: Secrets of the Deep]

Vast submarine network

The ship, then called the Dickenson, first set sail in early 1923 as part of a fleet of ships that maintained the growing submarine telecommunications network at the time.

via Live Science:

Remains of a 750-year-old city, founded by the descendants of Genghis Khan, have been unearthed along the Volga River in Russia.

Among the discoveries are two Christian temples one of which has stone carvings and fine ceramics.

The city’s name was Ukek and it was founded just a few decades after Genghis Khan died in 1227. After the great conqueror’s death his empire split apart and his grandson Batu Khan, who lived from 1205 to 1255, founded the Golden Horde (also called the Kipchak Khanate).The Golden Horde kingdom stretched from Eastern Europe to Central Asia and controlled many ofthe Silk Road trade routes that connected China to Medieval Europe.

Dracula’s dungeon discovered in Turkey

news-vlad

via Unexplained Mysteries:

The dungeon in which Vlad the Impaler was imprisoned by the Turks has been found at Tokat Castle.

Back at the beginning of the 15th century Wallachian Prince Vlad III, the real-life inspiration behind Bram Stoker’s character Dracula, was held captive by the Ottoman Turks for twelve years.

Now archaeologists believe that they have discovered the very prison in which he had been held captive deep beneath Tokat Castle in northern Turkey. The dungeons were found following the discovery of a secret tunnel that was unearthed while restoration works were being carried out on the building.

“The castle is completely surrounded by secret tunnels. It is very mysterious,” said archaeologist Ibrahim Çetin. “It is hard to estimate in which room Dracula was kept, but he was around here.”
