This is the 1st part of a short explainer article series on the current crisis in Yemen.

Since 2015, Yemen has been at war on two different fronts, 1) The Civil War between the Iran-backed Houthi rebels and the UAE-Saudi Arabia backed government headed by Abdrabbuh Mansur Hadi, and 2) the war against the local terrorist outfits of Al-Qaeda and ISIS.

However, last year one more complexity was added to the conflict when UAE withdrew from the coalition backing Hadi government and later threw its support behind another secessionist force in southern Yemen, which seeks to re-create the State of South Yemen, as it was before the unification of Yemen in 1990.

As of early this year, it has added another layer to the war: the failing healthcare infrastructure and the rise of COVID-19.

The staggering cost of this war in the past five years has prompted the UN to name it the worst man-made humanitarian crisis in history, with Some 24 million Yemeni people - 80 percent of the country's population - requiring assistance or protection.

This series of articles seeks to build historical context to follow the current events in Yemen, believing much of the recent media coverage to have been ignored, or otherwise made wholly uncontextualized in the process of following the crisis for over a decade.

The History

Much of the current conflict can only be understood as a result of the events of the latter half of the 20th century. Here is a brief look at the history that has shaped today’s wars in Yemen.

At the heart of several issues in the conflict is the fact that modern day Yemen was initially divided into North Yemen and South Yemen until 1990, when it was unified.

North Yemen:

The Yemen Arab Republic (YAR), a coalition in North Yemen, overthrew the Mutawakilite Kingdom in 1970, which had been ruling since Yemen’s decolonization, in 1918. The YAR established their capital at Sana’a, a site which will often be the site of conflict in the following years.
This part of Yemen, during the cold war  was backed the countries aligned with the anti-communist block like Saudi Arabia, Jordan, the US, the UK and West Germany. The influence of Saudi Arabia and their relations with the US will come to play a greater role in the following decades.

South Yemen:

This referred to the region that was under the British Raj as the Aden Protectorate, since 1874. It consisted of two-thirds of present-day Yemen. In 1937 it became a Province of the British Raj, and in 1963, it collapsed and an emergency declared. The collapse was the joint effort of the National Liberation Front (NLF) and the Front for the Liberation of Occupied South Yemen (FLOSY).

Aden was used by the East India Company as a coal depot, and to stop Arab pirates from harassing British-India trade. Until 1937, Aden was part of British India, officially titled the Aden Protectorate.

Aden, like Sana’a will come to be the capital of southern Yemen, and the site of many conflicts.

This part of Yemen, during the cold war was backed by the Cummunist bloc countries like USSR, Cuba, and East Germany.

The Unification:

North and South Yemen united in 1990, after several years of conflict with one another. The leader of North Yemen, Ali Abdullah Saleh, was named President of unified Yemen in 1990. He was to continue ruling over Yemen for over three decades.

The unification of Yemen finally fulfilled almost a century of struggle that started during the British occupation and continued at different paces throughout the monarchy and cold war period. This unification also took away the privileges and power vested with many important tribes and people. Unlike the political forces, the armed forces of North and South Yemen were not unified at the time of political unification of the country.

The disgruntled former elites and the partisan army provided the fertile ground for the first civil war of Yemen which followed shortly after the unification.

Xenobots: The first ever ‘living’ robots

Creating robots using artificial intelligence has become quite normal in this century. But a robot built with an amalgamation of artificial intelligence and biology is quite enthralling. Researchers from University of Vermont and Tufts University collaborated to conceive a living robot called ‘Xenobot’.

This astounding, millimeter-wide chunk of technology is considered to be ‘living’ as it is created by stem cells from the embryo of Xenopus laevis, an African frog species. These stem cells were selected in such a way that they grew out to be heart and skin cells.

Prior to this, computer scientists at the University of Vermont ran an evolutionary algorithm, which imitates natural selection, on their supercomputer, which yielded the most suitable structures of the robot. After selecting the best designs, biologists at the Tufts University moulded the skin and heart cells into the forms which closely resembled the outputs of the algorithm, through microsurgery.

The resulting biological bodies looked like tiny aliens. "They're neither a traditional robot nor a known species of animal. It's a new class of artifact: a living, programmable organism" said Joshua Bongard, a computer scientist and robotics expert at the University of Vermont, who was involved in the research. Detailed results are published in the Proceedings of the National Academy of Sciences (PNAS) research paper on January 13, 2020.

Newly created xenobots were found to swim in any liquid medium for at least 10 days (or more if put in a nutrient-rich environment) without being fed with any nourishment, since the cells have a reserve of embryonic energy.

Another incredible facet of this technology is that it can revamp any of its parts efficiently upon damage. While technological pieces made out of plastic and metal might cause a lot of pollution after they are disposed of, xenobots are completely biodegradable, causing no harm to the environment. "These xenobots are fully biodegradable, when they're done with their job after seven days, they're just dead skin cells" said Bongard.

One might wonder how these miniscule cell blotches are helpful to us. Well, Xenobots may be very small in size but they can achieve feats which almost no huge, metal-made robot can.

These living robots will be useful in certain fields like medicine wherein they could be utilized to clear plague from our arteries. They can also be modelled with pouches which enables them to carry certain substances. This property can be used for delivering drugs in specific parts of our bodies. Xenobots can also be a boon in the field of cancer biology as they can help reprogramming tumors into normal cells.

Additionally, these tiny biological bodies can be oceans’ best friends. With contaminants like radioactive chemicals, plastics and microplastics creating havoc in the marine world, an immediate need to clean up our water bodies arises. Many xenobots were observed to be moving in circles (an attribute of the beating heart cells), which resembled a ‘clean-up’ motion. Hence, these tiny robots can be a perfect tool to eradicate microplastics from the oceans as well as eliminating nuclear wastes.

Although this technology may be promising, certain ethical questions arise with every technological development, especially those involving biological manipulations. If programmed in a certain way, xenobots can also take over natural biological functions (maybe nerve cells to hamper brain function) and this can be used for nasty purposes.

Michael Levin who directs the Center for Regenerative and Developmental Biology at Tufts said, “That fear is not unreasonable. When we start to mess around with complex systems that we don't understand, we're going to get unintended consequences”. Levin and Bongard are extensively working towards understanding how complex systems work. "There's all of this innate creativity in life. We want to understand that more deeply—and how we can direct and push it toward new forms" said UVM's Josh Bongard.

Like any new disruptive technological innovation, the Xenobots also have the potential to prove boon or bane for the humankind. Let's hope it turns out more boon than bane.
