📰 New camera can see through human body
Can guide endoscope without X-rays
•Scientists in the U.K. have developed a camera that can see through the human body and track the medical tools known as endoscopes that are used to investigate a range of internal conditions.
•The device, developed by researchers at the University of Edinburgh and Heriot-Watt University in the U.K., is able to detect sources of light inside the body, such as the illuminated tip of the endoscope’s long flexible tube.
•Until now, it was not possible to track where an endoscope is located in the body in order to guide it to the right place without using X-rays or other expensive methods, researchers said. Light from the endoscope can pass through the body, but it usually scatters or bounces off tissues and organs rather than travelling straight through.
•This makes it nearly impossible to get a clear picture of where the endoscope is.
•The camera takes advantage of advanced technology that can detect individual particles of light, called photons.
•The technology is so sensitive that it can detect the tiny traces of light that pass through the body’s tissue from the light of the endoscope.
📰 BRICS declares Lashkar, Jaish as global terror groups
Move underscores a shift in China’s position vis-a-vis ties with Pakistan
•The Brazil-Russia-India-China-South Africa (BRICS) grouping unequivocally named Pakistan-based groups — Jaish-e-Mohammad (JeM) and Lashkar-e-Taiba (LeT) — as terror organisations, removing a key irritant in ties between New Delhi and Beijing and stepping up the fight against global extremism.
•A joint communiqué released at the BRICS summit on Monday expressed concern about the regional security situation and listed the Taliban, IS/Daesh, Al-Qaeda and its affiliates, including the Eastern Turkistan Islamic Movement, the Islamic Movement of Uzbekistan, the Haqqani network, Lashkar-e-Taiba, Jaish-e-Mohammad, TTP and Hizb-ut-Tahrir as sources of violence.
UN designation
•Asked if the declaration would advance efforts to impose a UN ban on Masood Azhar as an international terrorist, Priti Saran, Secretary (East) in the Ministry of External Affairs, said, “The declaration has been endorsed by all the BRICS leaders, so obviously it has the approval and endorsement of all the countries.”
•Stressing that the formulation adopted at the ninth BRICS summit would strengthen the fight for banning terrorists and terror groups at the UN, Ms. Saran said: “The BRICS leaders called for greater efficiency in designation of terrorists and terror groups by the United Nations Committee on terrorism.”
•Analysts say the BRICS declaration underscores a shift in China’s position on hyphenating its ties with India with its relationship with Pakistan. In the past, Beijing has repeatedly asked for a “technical hold” in designating the head of the Pakistan-based JeM as an international terrorist in the United Nations Security Council 1267 committee — a move that seemed to reflect its special ties with Islamabad.
•The joint statement, without exception, also deplored “all terrorist attacks worldwide,” including attacks in BRICS countries.
📰 Centre refuses to offer assurance on Rohingya
Plea in SC against deportation plan
•The Centre refused, in the Supreme Court, to give 40,000 Rohingya Muslim immigrants an assurance that it will not move for their deportation back to Myanmar.
•Additional Solicitor-General Tushar Mehta, for the Centre, remained non-committal on Monday when the two Rohingyas who moved the court tried to draw an assurance that the government would not move against their community or take “coercive steps.”
•“I am not making any such statements,” Mr. Mehta said categorically.
•Next hearing on September 11
•Listing the case for hearing on September 11, a Bench led by Chief Justice of India Dipak Misra asked advocate Prashant Bhushan, who appears for Mohammad Salimullah and Mohammad Shaqir, the two Rohingyas, to first serve the copy of their petition on the Centre. The court then asked Mr. Mehta to take instructions from the Centre.
📰 Who were the first settlers of India?
New research has pushed back the date for human occupation of Australia and South-east Asia. This is sparking a fresh debate on when our ancestors arrived in India first
•When did our species, Homo sapiens, first set foot in India? There are two competing versions of the answer: let’s call them the ‘early version’ and the ‘late version’. The ‘early version’ says they arrived 74,000 to 120,000 years ago from Africa through the Arabian peninsula with Middle Stone Age tools such as scrapers and points that helped them hunt their prey, gather food, or make clothes. The ‘late version’ says they arrived much later, around 50,000 to 60,000 years ago, with upgraded technology such as microlithic (tiny stone) tools that might have been used to give sharp tips to arrows and spears.
•A geological event separates the two versions: the supervolcanic eruption at Toba in Sumatra, Indonesia, about 74,000 years ago, dumped tonnes of ash all over South-east Asia and South Asia, causing much stress to all life in the region. The ‘early version’ says migrants reached India before Toba; the ‘late version’ says the opposite.
Two new studies
•Until two months ago it looked like the late version had all the momentum. But two new studies, published in July and August, may have changed that. The first study, led by Professor Chris Clarkson of the University of Queensland, established that modern humans were in Australia by between 59,300 and 70,700 years ago, or, if you take the midpoint, 65,000 years ago. That is about 15,000 years earlier than previous estimates. Prof. Clarkson and his colleagues used the latest techniques to date things left behind by humans at the Madjedbebe caves in Australia’s Northern Territory: mortars and pestles, ground-edge axes, and painting material.
•The second study, led by archaeologist Dr. Kira Westaway of the Macquarie University, palaeontologist Dr. Julien Louys of the Australian National University, and others had equally remarkable results. They reinvestigated two teeth that had been found in the Lida Ajer caves in Indonesia’s Sumatra island more than a century ago, but whose dating and provenance were disputed. Using the latest multidisciplinary techniques, they have confirmed that the teeth belonged to modern humans who lived 63,000-73,000 years ago, thus pushing back the dates for modern human occupation of South-east Asia by about 20,000 years.
•The Sumatra and the Madjedbebe findings point in the same direction, says Dr. Louys: that Out of Africa (OOA) migrants made it into South-east Asia before 60,000 years ago. In fact, he says, they could have been in the region for much longer because “it is incredibly likely we’re not sampling the very first humans in Sumatra and Australia.”
•But if people were already in Australia and South-east Asia by 65,000 years ago, then they would have had to have left Africa and reached India much earlier (India having been a key corridor for the OOA migration). And that would put the ‘late version’ in jeopardy. Professor Ravi Korisettar of the Karnatak University, a well-known archaeologist who has worked extensively on early modern human migrations in South Asia, concurs. “These findings support our argument for an earlier migration,” he says.
Why should we care?
•But wait a minute, why should anyone care? How does it matter when a group of hunter-gatherers first walked into India? The simple answer is that human history in the subcontinent begins with them. But there’s also another reason. The first settlers of India are our direct ancestors: about 50% to 60% of Indian genetic ancestry today comes from the first settlers, with the rest contributed by later migrants from West Asia, East Asia, and Central Asia. So, the deeply held belief that only tribals (about 8.6% of the population) carry the ancestry of the original settlers couldn’t be more wrong. The first settlers of India are, indeed, the bedrock of our population and civilisation. Without getting their story right, we cannot get the rest of our history right.
Jwalapuram and the early version
•So, to get back to our story, there’s a reason for Prof. Korisettar to feel vindicated. He was instrumental in discovering the Jwalapuram site in Andhra Pradesh, which posed the first big challenge to the ‘late version’. Jwalapuram lies in the Jurreru river valley and its significance is in the fact that the river basin holds layers of volcanic ash left behind by the Toba eruption. The archaeologists who excavated Jwalapuram more than a decade ago, including Prof. Korisettar and Prof. Michael Petraglia, then of Cambridge University, found something remarkable at the bottommost layer: Middle Stone Age tools dated to around 77,000 years ago and were made by what they believe were modern humans. Those findings created a stir because they frontally challenged the ‘late version’. Prof. Korisettar and Prof. Petraglia, in fact, went on to argue that modern humans could have been in India as early as 100,000-120,000 years ago. “Ever since our paper was published in Science magazine in July 2007, we have been suggesting pre-Toba expansion,” says Prof. Korisettar.
•The Jwalapuram findings did not go uncontested, though. Middle Stone Age tools were made by both modern humans and archaic hominins such as Homo erectus and are, therefore, difficult to assign to one or the other. And India has had archaic hominins at least from about 1.5 million years ago. But Prof. Korisettar argues that the Jwalapuram artefacts are remarkably similar to those made by Middle Stone Age modern humans in Africa. That argument now finds strong support from Dr. Louys who says “it makes sense” to think modern humans were in Asia before the Toba eruption.
The late version
•The problem is that this suggestion bumps up against genetics. All humans belong to haplogroups or lineages (Y-DNA haplogroups for males, and mitrochondrial or mtDNA haplogroups for females), and by studying current populations using genetic markers and mutation rates, geneticists can create global family trees and estimate the age at which two haplogroups shared a common ancestor. These techniques have improved by leaps and bounds, so it’s no surprise that there’s now near-consensus about the history of human migrations. It goes something like this: Homo sapiens originated in Africa over 200,000 years ago, started range expansions into the Levant and West Asia between 120,000-100,000 years ago, and started on a colonising journey of the world around 70,000 years ago, reaching South Asia by 60,000 years, Australia by 50,000 years, and Europe by 45,000 years ago.
•All non-African populations in the world, therefore, are descendants of a single, small group of migrating Africans (perhaps numbering no more than a thousand). Because of this bottleneck, the entire non-African world population belongs to just three mtDNA super-haplogroups M, N, and R (and C, D, and F in the case of non-African Y-DNA). The common ancestor of M, N, and R is a parent haplogroup called L3, which still has many lineages in Africa. Given this, it is reasonable to conclude that OOA migrations could not have happened earlier than the emergence of L3. And genetic studies say the earliest possible date for the emergence of L3 is 70,000 years ago. In other words, there is no way that an OOA migration could have happened before the Toba eruption of 74,000 years ago!
•Those who argue this also put forward other reasons why the ‘early version’ cannot hold. One of them is that genetic records show that the first migrants had spread across South Asia, South-east Asia, and Australia within a brief period of time before too many mutations could accumulate. And that means it must have been quite a sprint, in historical terms. The only way this could have been accomplished is if they took a coastal route from West Asia to India to South-east Asia and then, finally, Australia. A coastal route meant two things: one, the beach-hopping migrants could use the same skill sets to survive on marine resources such as fish and crustaceans all along their journey. Two, their march got an unintended directionality, taking them inexorably towards Australia.
•What lends support to this chronology is that at least from about 35,000 years ago, there is incontrovertible evidence of modern humans in South Asia, while evidence for earlier presence is circumstantial. The earliest modern human fossil in the region is from the Sri Lankan cave of Fa Hien, dated to 33,000-30,000 years ago. (Sri Lanka was then linked to the Indian landmass, as sea levels were lower). In India too, there is abundant evidence of microlithic tools from around the same time.
Squaring the circle
•There is an attractive parsimoniousness to the ‘late version’ and until now there hasn’t been abundant, securely dated evidence against it. Moreover, every recent genetic study has further confirmed the late version, the latest being “A genetic history of aboriginal Australia”, the lead author of which is Dr. Michael Westaway of Griffith University. “Our study added a lot more detail to the understanding of early migrations,” says Dr. Westaway. Co-author Dr. Sankar Subramanian acknowledges the difference between the findings of their study and that of the Madjedbebe study. “The age of the common ancestor estimated in our study is younger, about 40,000 years (as against 65,000 years of the Madjedbebe study),” he says, adding that the difference could be either because some of the early lineages have gone extinct and therefore do not show up in the genetic studies, or simply because the genetic study did not include samples from the Northern Territory, the area where Madjedbebe caves are located.
•So, how does one square this circle? The ‘late version’ cites genetics to say that OOA could not have happened before 70,000 years ago. But archaeological evidence says humans were already in Sumatra by around then. There are two ways of looking at this. The first is that the new findings do not really overturn the ‘late version’, but only stretch it to the maximum. The lower end of the Madjedbebe study puts the age of the artefacts at 59,300 years; that of the Sumatra study puts it at 63,000 years. Theoretically, both could fall within the extreme range of possibilities, with OOA migrants reaching Australia by 59,000 years ago, after having left Africa by 70,000 years ago. Another possibility is that the Madjedbebe and Sumatra people went extinct long ago, leaving behind artefacts and a couple of teeth, but without leaving a mark in the genetic pool as it exists today.
📰 Making up for lost time
In the past half century, India and Myanmar have lost the habit of thinking of themselves as neighbours
•Prime Minister Narendra Modi embarks on an official bilateral visit to Myanmar from September 5. This follows upon his earlier ASEAN-related visit in November 2014 and former Prime Minister Manmohan Singh’s visit in May 2012. Though overdue, taking into account Mr. Modi’s ‘Neighborhood First”, ‘Act East’ and diaspora policies, international and domestic developments since then have clarified the political context of the visit to an extent not possible earlier. These include the impact of elections in Myanmar in November 2015 and in the U.S. in late 2016 that brought Aung San Suu Kyi’s National League for Democracy (NLD) to power in Myanmar and Donald Trump in the U.S.; the finalisation of China’s Belt and Road Initiative (BRI) and its assertiveness in the South China Sea; the India-China border stand-off; and Myanmar’s travails over the peace process, the Rohingya issue and the economy.
The Rohingya crisis
•The visit is taking place amidst some of the worst violence involving Rohingya militants and the Myanmar security forces ever resulting in a full-fledged international crisis triggered by large-scale, coordinated attacks by Rohingya militants under a recently formed Arakan Rohingya Salvation Army (ARSA, now designated as ‘terrorists’) against government and security outposts in northern Rakhine state on August 25-26.
•The attacks and clearance operations against it have resulted in some 400 (and mounting) deaths, mostly Rohingya; widespread arson and burning of villages allegedly by both sides; displacement of thousands within Rakhine state and across the Naf river to Bangladesh; and severe disruption in food and humanitarian supplies. The Modi government has unequivocally condemned the “terrorist” attacks at a time when the security forces and Ms. Suu Kyi herself face heightened international criticism on the handling of the issue. This is likely to resonate in Mr. Modi’s favour in Myanmar.
•The visit is also taking place against the backdrop of uncertainties in the future India-China relationship caused by the now defused Doklam stand-off and the BRICS summit. Sensitive to its location between the two Asians giants, Myanmar is keen to leverage the growth potential of good relations with Asia’s two fastest growing economies. But it is also wary of its economic dependence on China, characterised by a largely extractive relationship focussed on natural resources and access to the Bay of Bengal where it already has an oil and gas terminal, concession to build a Special Economic Zone and seeks a possibly controlling stake in a natural deep sea harbour at Kyaukpyu that could form part of its ambitious BRI. The shadow of China is thus likely to loom large over the visit. Myanmar would welcome closer economic ties with India to balance and offset its domineering ties with China. Characterisations of a ‘Great Game East’ between India and China are, however, greatly overstated.
Focus on basics
•Beyond these topical issues, and the issue of Indian insurgent groups in Myanmar, which remain a matter of concern, the optics of Mr. Modi’s much anticipated visit will most likely be taken up by the fundamentals of the bilateral relationship: the substantive development partnership, trade issues, and revival of cultural and people-to-people ties. Defence relations too have been growing steadily, especially between the two armies and navies. Security related talks have been taking place at the National Security Adviser (NSA) level.
•A number of bilateral agreements in the areas of capacity building, health, culture, and development, and one on maritime security are on the anvil, building on India’s nearly $2 billion development partnership with Myanmar so far. These cover large directly funded and executed connectivity infrastructure projects like the Trilateral Highway, the Kaladan Multi-modal Transport and Transit Project; high value capacity and human development projects like the Myanmar Institute of Information Technology in Mandalay; more modest ones in industry, IT, health, entrepreneurship and language training; small border area development projects in Chin and Naga areas of Myanmar; and soft lines of credit for other infrastructure projects amounting to nearly $750 million. Much of this still remains to be utilised.
•Though this may not be adequately realised even in Myanmar, few countries are undertaking such large infrastructure and human development projects out of government funds as India is. When they are all completed and fully operational by about 2020, they will amount to a substantial mass and base for an expanded relationship.
•Lamentably, the same cannot be said of commercial trade and investments. Both stand on narrow bases, primary agricultural and forest products from Myanmar in the case of trade, and oil and gas in case of investments, underlining a strong need to expand, diversify and upgrade commercial ties in ways that also contribute to Myanmar’s development needs and meet India’s $3 billion trade target set in 2012.
•To an extent not often realised, trade has been the keystone of our post-Independence relationship that survived both the nationalisation of the 1960s by the military government of Ne Win and the Western economic sanctions since the crackdown on democratic aspirations starting from the 1980s. Critical to this trade are Indian imports of beans and pulses that play a vital part in our food security and Myanmar’s economy. Standing at around a million tonnes and $1 billion in value, over 90% of which is exported to India, it is vital to Myanmar’s farmers and foreign exchange earnings, greater even in the value of its exports of rice to China that are prone to periodic restrictions, tough inspections and crackdowns on informal trade at the Myanmar-China border. Past attempts to open a limited market for Myanmar rice in India as an alternative to China, have floundered on vested public distribution interests in India and should be re-opened.
•Unfortunately, the recent decision to impose quantitative restrictions on the trade in pulses does exactly the opposite, notwithstanding recent relaxations on orders already paid for. In part, this is because of our own concerns vis-à-visspeculative global trade in pulses that has resulted in incentives to increase and protect domestic production in India and induce Myanmar to move towards a government-channelised trade to stabilise prices and in part on account of resistance to such a move in Myanmar.
Older ties
•Underlining our strong cultural, people-to-people and diaspora relationship, Mr. Modi will also visit Bagan where the Archaeological Survey of India is in the final stages of a face-lift to the venerated Ananda Temple and where the Cabinet has approved Indian assistance for the restoration of pagodas damaged by the powerful 2016 earthquake; and Yangon, where he will address the Indian-origin and Indian community and visit places religious, cultural and historical importance.
•In his official meetings with President Htin Kyaw and State Counsellor Suu Kyi in Nay Pyi Taw, Mr. Modi is likely to forge a bold strategic vision for bilateral relations, taking advantage of the consensus cutting across political parties and civil and military pillars of Myanmar’s polity towards stronger ties with India and project India’s economic and strategic footprint in the region between the Bay of Bengal to the South China Sea.
•Key elements of this vision could be greater attention to emerging political forces, ethnic states and the peace process as part of our democratic political outreach; converting our investments in the Trilateral Highway and the Kaladan to fuller trade and investment corridors and use Indian investment in the Greater Mekong Sub-region as an arm of our foreign policy with a focus on agriculture, agro-industries and light industry; a broader development partnership reaching to the grassroots with the help of civil society; specific prongs in our ‘Act East’ policy through the Northeast and Bodh Gaya as a pilgrimage centre; and a new political approach to the IIG issue (Indian Insurgent Groups) beyond an intelligence-based approaches. These could perhaps find expression in a joint document sooner or later.
•The objective should be to restore the balance in Myanmar’s relations between East and South Asia that has been lost with the eastward tilt in Myanmar’s external relations over 50 years of insular military rule during which the two countries have forgotten the habit of thinking of themselves psychologically as immediate neighbours.
📰 Down but not out
The failed PSLV attempt to launch a navigation satellite is unlikely to affect future missions
•After 39 consecutive successful launches, the Indian Space Research Organisation had almost made it appear that launching satellites was indeed child’s play when it used its workhorse rocket, the Polar Satellite Launch Vehicle. But the PSLV, which has been placing satellites in their respective orbits for the past 24 years, faced a setback on August 31. The PSLV-C39 rocket carrying the eighth satellite of the Indian Regional Navigation Satellite System (IRNSS) had a normal lift-off and flight events but ended in an unsuccessful mission. The heat-shield failed to separate, resulting in the satellite separation occurring within the shield. This is just the second instance when the PSLV has had an unsuccessful mission in all of its 41 launches; the first setback was back in 1993. Over the years, the PSLV has played a pivotal role in ISRO’s programme, and this February it set a world record by launching 104 satellites in one go. With such an enviable track record, the failure of the mission this time almost comes as a surprise. This is especially so as the lift-off and the stage separation of the first and second stages, which are the most challenging parts of the mission, went off smoothly. In comparison, the heat-shield separation is a relatively minor operation which takes place once the rocket crosses an altitude of 100-110 km, and the temperature in the absence of the heat-shield will no longer damage the satellite. The failed mission serves as a reminder that utmost care and scrutiny are required before every single launch. While scientists are working to identify the cause of the anomaly in the heat-shield separation event, the failed mission should have no impact on future launches involving the vehicle.
•The failure of the mission is particularly disheartening as the IRNSS-1H satellite was jointly assembled and tested by ISRO and a Bengaluru-based private company, the first time a single private company, rather than a consortium, was involved in building a satellite. The satellite was in no way to blame for the failure of the mission. The space organisation has thrown open its doors to private companies to build as many as 18 spacecraft a year beginning mid or end-2018. The IRNSS-1H satellite was launched as a replacement for the IRNSS-1A satellite, which became inoperational in terms of surveillance following the failure of all three atomic clocks. As only six of the seven satellites are operational, there are gaps in the navigation data sent by the IRNSS. With the failure of this mission, India will have to wait for some more time before the next mission to send a replacement for the IRNSS-1A satellite is ready. The IRNSS was created so that the country would not need to rely on American-based GPS data — the encrypted, accurate positioning and navigation information provided by the system will make Indian military operations self-reliant.
