Iran is the hardest-hit country by the coronavirus pandemic in the middle east. The contagion was first detected on 19 February 2020 in the holy city of Qom, and thereafter spread quickly across the country. As of 18th June 2020, it had over 9000 coronavirus related fatalities. The virus attacked all the 31 provinces of the country not discriminating between the common man and the people at high places including the members of the Parliament, religious leaders and senior ministers. The crisis touched most parts of the country, but it most severely impacted working and the poor class. 

The Iranian government has been criticized for its response towards the pandemic. The health care policy, which has been politicized, has preferred denial and misinformation as a response to the crisis the pandemic brought with it. Questions have also been raised about the role of US sanctions in crippling Iran’s economy, public health facilities and public health facilities. All these factors, when combined, have disabled Tehran (the capital of Iran) from providing the best response to the pandemic. 

What do the sanction laws say?

According to the Office of Foreign Assets Control, the US has “consistently maintained broad exceptions and authorizations to support humanitarian transactions with Iran.” The first significant sanctions were imposed in 1995 by Bill Clinton, and in 2001 exemptions for medical goods and medicine first came into effect. These sanctions have periodically widened the scope of products for exemption, and by 2012, the exclusions included agricultural products and most foods. After the world powers, including the US, reached a deal with Iran on its nuclear programme in 2015, the sanctions were lowered against Iran. This approach was abandoned after Trump withdrew the US from the deal and sought to force Iran’s leaders to change their anti-US policy. .

The US sanctions are enforced through a wide array of instruments. Financial sanctions prohibit US banks from transacting with Iran, which limits Iran’s access to dollar-denominated transactions. Secondary sanctions measures also target non-US entities that have dealings with Iran, thus at a risk of facing prosecution in the US. These sanctions make transactions with Iran lengthy and complicated, and even impossible in some cases

There are some exemptions from sanctions for humanitarian assistance (sale of agricultural commodities, food, medicine and agricultural services). Despite these exemptions, sanctions have severely impaired Iran’s ability to be able to finance humanitarian imports. Given the volume of complexity and due diligence involved, most banks are reluctant to deal with Iran. This makes it difficult to find a way to pay for purchases difficult for Iran. Also many items require additional authorization because the US considers them as “dual-use” (the things might also be used for defence- for example, the sort of oxygen generators that are needed in life support machines used to treat coronavirus cases). Lastly, the sanctions on Iran’s oil exports led to a decline in revenue, further weakening Iran’s currency, which has left the country vulnerable and with fewer resources to pay for non-sanctioned items as well. 

All these put together have directly caused shortages of medical equipment and impacted Iran’s health sector negatively. This has also impacted the capability of Iranian healthcare sector to effectively manage the COVID-19 situation.

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.
