DNA tech means remains of AI crash victims will reach their kin. It has also changed the world
When Garuda Airways flight 152 crashed on Sept 26, 1997, many of the 234 fliers were mutilated beyond recognition. Eventually, 48 were interred in a mass grave. Thanks to advancements in DNA matching since then, kin of the Air India crash victims have been spared this pain. At least 135 of the 270 victims – many of them completely charred – have already been identified. Officials hope to complete the task by Wednesday.
It's a measure of technology's march since scientist Alec Jeffreys found the first genetic fingerprint on Sept 10, 1984. He didn't discover DNA – that honour goes to Swiss scientist Friedrich Miescher, who made the discovery in 1869, the year Mahatma Gandhi was born. But then, not much happened for the next 115 years. Yes, Watson and Crick figured out DNA's structure and won a Nobel in 1962, but DNA didn't have practical uses until Jeffreys' eureka moment. Within a year, he had helped a boy get British citizenship by establishing a DNA link between him and his parents. The year after, he helped nail the culprit in a double rape and murder case. US caught on in 1986, and by 2013 its Department of Justice was collecting and analysing DNA samples for $40 a pop.
Now, you can order a DNA paternity test online. Sequencing machines have become tiny – the smallest ones weigh less than a smartphone and cost around $3,000. US troops used one to identify IS leader Baghdadi on their chopper in 2019. Meanwhile, over 40mn people have given DNA samples to private firms to trace their ancestry. In recent weeks, DNA has revealed mix-ups that happened in hospitals in 1940s when newborns weren't tagged. It's solved decades-old crimes, and freed innocents who lost their youth in jail. It's a gift that keeps on giving.

Ahmedabad: Over a week after 270 people were killed in the Ahmedabad plane crash, 231 victims have been identified through DNA tests, and the bodies of 210 of them were handed over to their families, a health official said on Friday. A London-bound Air India flight AI-171 carrying 242 passengers and crew members crashed in Ahmedabad on June 12. All but one on board the plane died along with nearly 29 on the ground when the aircraft smashed into a medical complex in Meghaninagar area of the city shortly after its take-off. Authorities are carrying out DNA matching to establish the identity of the victims, as several bodies were charred beyond recognition or damaged. "Till Friday evening, 231 DNA samples have been matched and relatives have been contacted. So far, the mortal remains of 210 victims have been handed over to families," Medical Superintendent of Ahmedabad Civil Hospital Rakesh Joshi said. The 210 victims comprise 166 Indians, 36 British nationals, seven Portuguese nationals and one Canadian, he said. Of the 166 Indians, a total of 155 were on board the ill-fated aircraft, Joshi informed. The Indian victims who were identified so far belonged to various parts of the country, including Gujarat, Rajasthan, Maharashtra, Diu and Nagaland, he said. The state government had earlier said that samples of 250 victims, including persons on board the ill-fated flight as well as those killed on the ground, were collected for identification.

Detention of Bengal BJP chief, London-based doctor sparks political row

In a dramatic turn of events in West Bengal, Kolkata Police on Friday detained the state Bharatiya Janata Party president and a London-based doctor, sparking a major political controversy. Police had allegedly blocked Bengal BJP chief Sukanta Majumdar (R) from meeting the doctor, saying he was not at home. (Screengrab/X/@BJP4Bengal) Union minister and West Bengal BJP chief Sukanta Majumdar had visited the residence of UK-based doctor Rajatshubhra Bandyopadhyay on Harish Mukherjee Road in Kolkata when the incident took place. The issue comes against the backdrop of Dr Bandyopadhyay's 'Kellogg College Lecture' controversy with West Bengal chief minister Mamata Banerjee, which took place in March. The now-viral confrontation saw the doctor asking Mamata Banerjee to name a single major industry that had come to Bengal during her tenure. The question triggered such chaos that university security was forced to intervene. Bandyopadhyay, a British passport holder with his origin in South Kolkata, was later released by the police. However, with the duo's detention, the BJP accused the Mamata Banerjee-led government of using the police to "muzzle dissent" and "criminalise symbolic gestures". In a post on X, the saffron party's state unit posted raised concern over the "alarming" situation in Bengal, where 'even a Union Minister is denied the basic courtesy of meeting a respected doctor! What could be a more shocking example of lawlessness and political vendetta!' As Majumdar's convoy neared the doctor's residence, police intercepted it and allegedly claimed that Bandyopadhyay was "not at home". "But the truth is, the doctor was very much at home and waited for over an hour to meet Dr. Sukanta Majumdar," the BJP stated. The doctor later stepped out of the residential complex and met the West Bengal BJP chief on the side of the road. Their interaction was cut short by the police, who detained both of them without "giving any reason", the party said. Police took both Majumdar and the doctor to the city headquarters at Lalbazar, even as party workers attempted to resist. While being escorted into a police van, Majumdar told reporters, "For what reason have we been detained? I have no clue. Nowhere in the world does something like this happen." Meanwhile, after being released, Bandyopadhyay spoke to reporters as well and said, "Is this the way to treat a British citizen? What crime have I committed? Is it a crime to meet a Union minister in Bengal? The police need to answer on what grounds I was picked up like a criminal." The BJP state unit said that this was a "clear demonstration" of CM Mamata Banerjee "wants to silence every voice being raised". BJP leader Sourav Sikdar described the detention as nothing short of "state-sponsored goondaism". "They are scared of a doctor who asked questions and a minister who came to meet him. The state is weaponizing the police," he claimed. Meanwhile, the Mamata Banerjee-led Trinamool Congress defended the police's action and accused the BJP of "stage-managing provocations". "The BJP is creating deliberate provocations in sensitive areas. The doctor in question has a track record of inciting controversies. The police acted in accordance with law to ensure peace," said TMC spokesperson Kunal Ghosh.

How pro-Palestine activists broke into UK's largest airbase

Palestine Action, a UK-based Palestine advocacy group, entered the Royal Air Force's Brize Norton airbase and defaced two military aircraft with spray paint. UK Prime Minister Keir Starmer has described the act as 'disgraceful' and 'vandalism'. But how did they manage to breach the base's defences? read more Palestine Action, a UK-based Palestine advocacy group, put up a video of the incident on social media. Image courtesy: X Pro-Palestinian activists have broken into the UK's largest airbase. Palestine Action, a UK-based Palestine advocacy group, entered the Royal Air Force's Brize Norton airbase and defaced two military aircraft with spray paint. UK Prime Minister Keir Starmer has described the act 'disgraceful' and 'vandalism'. But what happened? Why is this a big deal? What do we know about the group? Let's take a closer look What happened? First, let's take a brief look at the group. Palestine Action's website describes it as 'direct action movement committed to ending global participation in Israel's genocidal and apartheid regime'. STORY CONTINUES BELOW THIS AD It says its main target is Elbit Systems – which is the biggest weapons manufacturer for Israel. Palestine Action says its strategy is to take 'sustained and focused direct action against key targets' to topple Israel's military-industrial complex. Now let's take a look at what happened on Friday night. Palestine Action said two of its members broke into the RAF's Brize Norton airbase in central England's Oxfordshire. The group's members spray painted two military aircraft with red paint – symbolising blood – including into its turbines. The group also spray painted the red paint on the runway and put up a Palestinian flag. The group put up a video of its actions on X. BREAKING: Palestine Action break into RAF Brize Norton and damage two military aircrafts. Flights depart daily from the base to RAF Akrotiri in Cyprus. From Cyprus, British planes collect intelligence, refuel fighter jets and transport weapons to commit genocide in Gaza. — Palestine Action (@Pal_action) June 20, 2025 'Despite publicly condemning the Israeli government, Britain continues to send military cargo, fly spy planes over Gaza and refuel ../Israeli fighter jets,' the group said in a statement. STORY CONTINUES BELOW THIS AD 'Britain isn't just complicit, it's an active participant in the Gaza genocide and war crimes across the Middle East,' Palestine Action said in a statement. 'By decommissioning two military planes, Palestine Action have directly intervened in the genocide and prevented crimes against the Palestinian people,' it added. Why does this matter? Because this is a huge embarrassment for the British government. Brize Norton, with over 6000 employees, is the UK's largest airbase. It is also the place the British refuelling fleet calls home. One of the craft on the base is used to fly the King and Prime Minister on official engagements. However, defence sources told The Telegraph that Palestine Action were mistaken and that the UK does not help refuel planes that participate in Israeli military operations. This was backed up by a source that told CNN that RAF Voyagers do not carry any weapons for Israeli forces or help refuel their aircraft. A spokesperson for Starmer said the government was reviewing security across all British defence sites. UK Prime Minister Keir Starmer has described the act 'disgraceful' and 'vandalism'. Reuters Britain's defence ministry and police were investigating. STORY CONTINUES BELOW THIS AD 'It is our responsibility to support those who defend us,' the defence ministry said. It slammed the 'vandalism of Royal Air Force assets'. Lord West, Labour minister for UK security, called the development extremely worrying". 'We can't allow thing like this to happen at all,' West, former head of the Royal Navy told BBC. He added that such developments were 'really a problem' for national security.
