The civil war in Yemen, more so after 2015 has taken a toll on the civic infrastructure of the already fragile and poor country. Among these, the healthcare infrastructure of the country was one of the worst affected.

Apart from the physical damage to the hospitals and clinics due to the aerial bombings by the Saudi Arabia led coalition, the naval blockades exacerbated the dire situation. In June 2015 itself, aid agencies warned of the humanitarian risks brought by the US and UK-backed Saudi blockades.

The humanitarian situation aggravated further as there was a consistent famine since 2016 and Yemen was dependent on foreign aid for feeding almost 80% of its population.  According to UNICEF reports, over 3.3 million children and pregnant or lactating women suffer from acute malnutrition.

In 2017, the World Food Programme estimated that an additional 3.2 million people would be pushed into hunger. If left untreated, 150,000 malnourished children could die within the coming months.

Save the Children, the international charity and aid agency, estimated that 85,000 children under the age of five have starved to death in between 2015 to 2018.

Major healthcare operatives are dying due to the active bombing and conflict in Yemen, including personnel from MSF and United Nations Office for Coordination of Humanitarian Affairs (OCHO).

The MSF (or Doctors Without Borders), who have been in Yemen since 2007, have reported that fears of stigmatization are causing people to stay away from hospitals, with misinformation and lack of medical services only compounding the healthcare issue during the pandemic.

As of 24th July, the country reports 1640 confirmed infections and 458 related deaths.  Al Jazeera reported that “Cemeteries in Aden are overflowing with graves, suggesting that the number of people killed by the new coronavirus is higher than the official count.” Yemen and its related aid agencies also suffer from lack of PPEs and adequate information about the pandemic.

As of April 2020, there are 800,000 internally displaced persons in just one province of Yemen Marib. The number of verified civilian deaths stands at 7,700.

The United Nations has been continually asking for donations, but has failed to collect as much as it requires. While it collected $4 billion last year, it has only received $700 million, halfway into 2020.

The UN urged for $2.4 billion this year to fight the humanitarian crises and the Coronavirus. As of 2nd June, 29 countries and the European Commission pledged a total of $1.35 billion to support humanitarian efforts in Yemen, just over half of the amount needed to sustain programs through the end of this year.

In April 2020, the Saudi deputy defence minister, Prince Khalid bin Salman, said Saudi Arabia “will contribute $500m to the UN humanitarian relief program for Yemen in 2020, and an additional $25m to help combat the pandemic. It is up to Houthis to put the health and safety of the Yemeni people above all else.”

There are 41 major UN programmes in Yemen, and it is estimated that more than 30 of them will close due to lack of funds. The UN stated, “Due to the COVID-19 suppression measures, all integrated outreach activities, which include the Expanded Programme on Immunization, Integrated Management of Childhood Illness, Maternal and Newborn Health,and nutrition activities, were suspended.”

Most of Yemen's 3,500 medical facilities have been damaged or destroyed in air strikes, and only half are thought to be fully functioning. Officials warn that monetary relief may not be enough to assist in the war against the pandemic alongside the Civil War. A solution to the war must be found soon, before the pandemic eviscerates more of the healthcare infrastructure.

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.
