Ancient Carvings Discovered at Iconic Mosul Monument Bulldozed by ISIS

When ISIS bulldozed the ancient monumental Mashki gate in the Iraqi city of Mosul in 2016, it was part of the extremists' systematic destruction of cultural heritage.

Now, US and Iraqi archaeologists working to reconstruct the site have unearthed extraordinary 2,700-year-old rock carvings among the ruins, AFP reported.

They include eight finely made marble bas-relief carvings depicting war scenes from the rule of the Assyrian kings in the ancient city of Nineveh, a local Iraqi official said Wednesday.

Discovered last week, the detailed carvings show a soldier drawing back a bow in preparation to fire an arrow, as well as finely chiseled vine leaves and palms.

The grey stone carvings date to the rule of King Sennacherib, in power from 705-681 BC, according to a statement from the Iraqi Council of Antiquities and Heritage.

Sennacherib was responsible for expanding Nineveh as the Assyrians' imperial capital and largest city -- siting on a major crossroads between the Mediterranean and the Iranian plateau -- including constructing a magnificent palace.

Fadel Mohammed Khodr, head of the Iraqi archaeological team working to restore the site, said the carvings were likely taken from Sennacherib's palace and used as construction material for the gate.

"We believe that these carvings were moved from the palace of Sennacherib and reused by the grandson of the king, to renovate the gate of Mashki and to enlarge the guard room", Khodr said.

When they were used in the gate, the area of the carvings poking out above ground was erased.

"Only the part buried underground has retained its carvings," Khodr added.

ALIPH, the Swiss-based International Alliance for the Protection of Heritage in Conflict Areas, said the Mashki gate had been an "exceptional building".

ISIS targeted the fortified gate, which had been restored in the 1970s, because it was an "iconic part of Mosul's skyline, a symbol of the city's long history", it added.

ALIPH is supporting the reconstruction of the Mashki Gate by a team of archaeologists from Iraq's Mosul University alongside US experts from the University of Pennsylvania.

The restoration project, which is being carried out in collaboration with Iraqi antiquities authorities, aims to turn the damaged monument into an educational center on Nineveh's history.

A scientist guides a long tube into the mouth and down to the stomach of Thing 1, a two-month-old calf that is part of a research project aiming to prevent cows from burping methane, a potent greenhouse gas.

Paulo de Meo Filho, a postdoctoral researcher at University of California, Davis, is part of an ambitious experiment aiming to develop a pill to transform cow gut bacteria so it emits less or no methane.

While the fossil fuel industry and some natural sources emit methane, cattle farming has become a major climate concern due to the sheer volume of the cows' emissions.

"Almost half of the increase in (global) temperature that we've had so far, it's been because of methane," said Ermias Kebreab, an animal science professor at UC Davis.

Methane, the second largest contributor to climate change after carbon dioxide, breaks down faster than CO2 but is more potent.

"Methane lives in the atmosphere for about 12 years" unlike carbon dioxide which persists for centuries, Kebreab said.

"If you start reducing methane now, we can actually see the effect on the temperature very quickly."

Filho uses the tube to extract liquid from Thing 1's rumen -- the first stomach compartment containing partially digested food.

Using the rumen liquid samples, the scientists are studying the microbes that convert hydrogen into methane, which is not digested by the cow but instead burped out.

A single cow will burp roughly 220 pounds (100 kilograms) of the gas annually.

- 'Social critters' -

Thing 1 and other calves receive a seaweed-supplemented diet to reduce methane production.

Scientists hope to achieve similar results by introducing genetically modified microbes that soak up hydrogen, starving methane-producing bacteria at the source.

However, the team proceeds cautiously.

"We can't just simply cut down methane production by removing" methane-making bacteria, as hydrogen could accumulate to the point of harming the animal, warned Matthias Hess, who runs the UC Davis lab.

"Microbes are kind of social critters. They really like to live together," he said.

"The way they interact and affect each other impacts the overall function of the ecosystem."

Hess's students test different formulas in bioreactors, vessels that reproduce microorganisms' living conditions in a stomach from movements to temperature.

- More productive cows -

The project is being carried out at UC Davis as well as UC Berkeley's Innovative Genomics Institute (IGI).

IGI scientists are trying to identify the right microbe -- the one they hope to genetically alter to supplant methane-producing microbes.

The modified microorganisms will then be tested at UC Davis in the lab and in the animals.

"Not only are we trying to reduce methane emissions, but you also increase the feed efficiency," said Kebreab.

"Hydrogen and methane, they are both energy, and so if you reduce that energy and redirect it to something else... we have a better productivity and lower emissions at the same time."

The ultimate goal is a single-dose treatment administered early in life, since most cattle graze freely and can't receive daily supplements.

The three research teams have been given $70 million and seven years to achieve a breakthrough.

Kebreab has long studied sustainable livestock practices and pushes back against calls to reduce meat consumption to save the planet.

While acknowledging this might work for healthy adults in developed nations, he pointed to countries like Indonesia, where the government is seeking to increase meat and dairy production because 20 percent of children under five suffer from stunted growth.

"We can't tell them to not eat meat," he said.
