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.

Constructing Panopticon: Israeli Surveillance Technology and its Implications for the Palestinians

Jeremy Bentham, an English philosopher and social theorist designed ‘Panopticon’ in the late 18th century. The panopticon is an institutional building which Bentham describes as “a new mode of obtaining power of mind over mind in a quantity hitherto without example”. The structure's central observation tower, placed within a circle of prison cells, allows a watchman to monitor the inmates of the building without the dwellers knowing whether or not they are being watched. Although it is physically impossible for a single watchman to observe all the occupants at once, the fact that the inmates cannot know when they are being watched means that they are motivated to act as though they are being watched at all times. Thus, compelling the inmates to regulate their own behaviour.

Michel Foucoault, a French Philosopher, uses panopticon as a metaphor to explore relations between systems of social control and people in a disciplinary situation. For Foucault, the real danger was not that the individuals are repressed by the social order but the fact that when only certain people or groups of people control knowledge, oppression is a possibility. Contemporary society uses technology for the deployment of panoptic structures ‘invisibly’ throughout society.

This article gives an overview of the massive panopticon that is built and operated by Israel in Occupied Palestine.

Israel’s unaccountable military rule over its Palestinian citizens in east Jeruselum, West Bank and Gaza Strip have kept the Palestinians under constant surveillance and control. As per a report by Amitai Ziv on Haaretz, Israel’s surveillance operation against Palestinians is (as of 2019) “among the largest of its kind in the world. It includes monitoring the media, social media and the population as a whole.”

Among various mechanisms of surveillance, the technological mechanisms of surveillance and control deployed or proposed in the region of Gaza Strip is most empowering to Israel in terms of gathering ‘intelligence’. This includes use of biometric identity cards, Israeli access to Palestinian census data, almost complete access to and control of the telecommunication infrastructure in the Gaza Strip, the ability to track individuals via cell phone, large surveillance zeppelins which monitor the entire electromagnetic spectrum and which can usurp control of these from Palestinian operators (for instance sending text messages to subscribers targeting different demographics) as well as optical surveillance, facial recognition technology, remote controlled and robotic machine gun towers guarding the border that are capable of identifying a target and opening fire automatically—without human intervention.

In the context of occupation, the use of biometric ID cards of Israeli citizens is the sharpest seepage of control technologies.  For a long time, Israel has used a system of differentiated ID cards to distinguish between Jewish and Non-Jewish, citizens and residents of Israel, and citizens and residents of the occupied territories.

These ID cards also have a record of ethnic/religious affiliation of the person, and the ID numbers themselves are coded so as to reflect this information. One’s status of whether they are an Israeli or Palestinian, whether they are a citizen or a resident determines their freedom to travel, their ability to find jobs, and even their ability to get married and avail social benefits.  The Palestinians in East Jerusalem—which was annexed after the 1967 war—are considered as “conditional residents” and not citizens. According to a Human Rights Watch report, a resident of Palestine occupied Israel reported that the Israeli authorities refused to issue birth certificates to his five children, all born in Jerusalem. Other Jerusalem residents without residency status, in their testimonials, described being unable to legally work; obtain social welfare benefits; attend weddings and funerals; or visit gravely ill relatives abroad, for fear Israeli authorities would refuse to allow them to return home.

Another significant technological mechanism is the Facial recognition technology which has found its way into use by Israeli police. Facial recognition system, a globally controversial and scientifically flawed system is being used by the police force in Israel to identify protestors and is also implemented at airports and border crossings.

Israel has also ratcheted its social media surveillance, especially Facebook, Palestinians’ preferred platform. In October 2015, Israeli invasion at the Al-Aqsa Mosque angered several Palestinians. Many teenagers who didn’t belong to military wing or the Palestinian political faction orchestrated the attacks. The Israeli government blamed the social media for instigating the attacks and the military intelligence increased the monitoring of Palestinian social media accounts. Consequently, over 800 Palestinians were arrested for their posts on social media, particularly Facebook. It was later revealed that these arrests were a result of a policing system which uses algorithms to build profiles of supposed Palestinian attackers. This system proctors thousands of Palestinian Facebook accounts sifting for words like shaheed (martyr), Zionist state, Al Quds (Jerusalem), or Al Aqsa. Further, the algorithm identifies a “suspect” based on ‘prediction’ of violence. These targets are marked suspicious and are a potential target for arrest on the grounds of “incitement to violence”. The term incitement refers to all types of resistance to Israeli practices. The Israeli Army declared Military order 1651 in 2010, according to which, anyone who “attempts, orally or otherwise, to influence public opinion in the West Bank area in a manner which may harm public peace or public order” or “publishes words of praise, sympathy or support for a hostile organization, its actions or objectives,” will serve a jail time of 10 years. The order defines this as “incitement”. One notable instance has been the poetry of Dareen Tatour. She is a Palestinian citizen of Israel. She expressed her call to “resist” the occupiers through a poem she posted online in October 2015. The video had less than 300 views. But it resulted in nearly three years of house arrest and five months imprisonment. The Israeli government charged Tatour with inciting violence and terrorism while her poem was a call for a non-violent resistance. This incident is a classic demonstration of how Israel uses vague terminology to criminalize online activity when it serves its discriminatory interests.  

Israel’s military industrial complex is a profound enabler of the digital surveillance of Palestinians. The nation not only implements surveillance and control but also manufactures and exports a massive amount of military and cyber security technologies. A report published by Privacy International—an NGO that investigates government surveillance and companies—in 2016—stated that Israel has about 27 surveillance companies which is the highest per capita in terms of surveillance that any country has in the world.

The Guardian collected testimonies from people who worked in the Israeli Intelligence Corps to understand the big brother surveillance of the Palestinians. One of the testimonies revealed that commoners and even completely innocent people were under the radar of surveillance. The attestor stated “As a soldier in Unit 8200, I collected information on people accused of either attacking Israelis, trying to attack Israelis, desiring to harm Israelis, and considering attacking Israelis. I also collected information on people who were completely innocent, and whose only crime was that they interested the Israeli security system for various reasons. For reasons they had absolutely no way of knowing. All Palestinians are exposed to non-stop monitoring without any legal protection. Junior soldiers can decide when someone is a target for the collection of information. There is no procedure in place to determine whether the violation of the individual’s rights is necessarily justifiable. The notion of rights for Palestinians does not exist at all. Not even as an idea to be disregarded.”

Another testimonial exposed that the data collected was hardly in accordance with the security needs. The testimony stated, “Throughout my service, I discovered that many Israeli initiatives within the Palestinian arena are directed at things that are not related to intelligence. I worked a lot on gathering information on political issues. Some could be seen as related to objectives that serve security needs, such as the suppression of Hamas institutions, while others could not. Some were political objectives that did not even fall within the Israeli consensus, such as strengthening Israel’s stance at the expense of the Palestinian position. Such objectives do not serve the security system but rather agendas of certain politicians. One project in particular, was shocking to many of us as we were exposed to it. The information was almost directly transferred to political players and not to other sections of the security system. This made it clear to me that we were dealing with information that was hardly connected to security needs. We knew the detailed medical conditions of some of our targets, and our goals developed around them. I’m not sure what was done with this information. I felt bad knowing each of their precise problems, and that we would talk and laugh about this information freely. Or, for instance, that we knew exactly who was cheating on their wife, with whom, and how often.”

While hidden and unknown surveillance is prominent, Israel has also imposed explicit panopticon surveillance and restrictions on Palestinians in numerous cases. In the village of Beit Ijza, northwest of Jerusalem, the house of Gharib’s family has been enclosed by a 6-meter-high fence, cutting them off from their olive gardens and rest of the village as Israel claimed ownership of the land surrounding the Gharib family's house and created a West Bank settlement over there. The house was built in 1979 on land the family says has belonged to them from as far back as the Ottoman era. “Ever since Israel occupied the West Bank, Jews have been offering my father to sell the house,” Gharib says. “They even brought him a suitcase of money. He refused.” Now, their every move is filmed as cameras have been set up on the bars of the fence. Along with loss of privacy, the panopticon internalized omniscience prevents the Gharib family from taking radical steps to protect their rights. In Israeli military language this is called an “indicative fence” which is also equipped with sensors.  When the fence was built, the family had to negotiate by phone with the police at the nearby Atarot industrial zone every time they wanted to go out and or they had to get the Red Cross to help out. “Sometimes we waited for several hours for them to come and open it” Gharib said.

Constant surveillance in real life as well as digital space is definitely a critical human rights violation. While the case of Palestinians is unique given the Israeli military occupation, the fight for their rights is global. World leaders, governments, civil societies, social media giants and all internet users have an essential role in the battle for a surveillance and censorship free state.
