An international archeological mission has uncovered the remnants of what is believed to be a 5,000-year-old restaurant or tavern in the ancient city of Lagash in southern Iraq.

The discovery of the ancient dining hall — complete with a rudimentary refrigeration system, hundreds of roughly made clay bowls and the fossilized remains of an overcooked fish — announced in late January by a University of Pennsylvania-led team, generated some buzz beyond Iraq’s borders.

It came against the backdrop of a resurgence of archeology in a country often referred to as the “cradle of civilization,” but where archeological exploration has been stunted by decades of conflict before and after the US invasion of 2003. Those events exposed the country's rich sites and collections to the looting of tens of thousands of artifacts.

“The impacts of looting on the field of archeology were very severe,” Laith Majid Hussein, director of the State Board of Antiquities and Heritage of Iraq, told The Associated Press. “Unfortunately, the wars and periods of instability have greatly affected the situation in the country in general.”

With relative calm prevailing over the past few years, the digs have returned. At the same time, thousands of stolen artifacts have been repatriated, offering hope of an archeological renaissance.
“‘Improving’ is a good term to describe it, or ‘healing’ or ‘recovering,’” said Jaafar Jotheri, a professor of archeology at University of Al-Qadisiyah, describing the current state of the field in his country.

Iraq is home to six UNESCO-listed World Heritage Sites, among them the ancient city of Babylon, the site of several ancient empires under rulers like Hammurabi and Nebuchadnezzar.

In the years before the 2003 US invasion, a limited number of international teams came to dig at sites in Iraq. During Saddam Hussein’s rule, Jotheri said, the foreign archeologists who did come were under strict monitoring by a suspicious government in Baghdad, limiting their contacts with locals. There was little opportunity to transfer skills or technology to local archeologists, he said, meaning that the international presence brought “no benefit for Iraq.”

The country's ancient sites faced “two waves of destruction,” Jotheri said, the first after harsh international sanctions were imposed following Iraq’s 1990 invasion of Kuwait and desperate Iraqis “found artifacts and looting as a form of income” and the second in 2003 following the US invasion, when “everything collapsed.”

Amid the ensuing security vacuum and rise of ISIS, excavations all but shut down for nearly a decade in southern Iraq, while continuing in the more stable northern Kurdish-controlled area. Ancient sites were looted and artifacts smuggled abroad.

The first international teams to return to southern Iraq came in 2014 but their numbers grew haltingly after that.

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.
