  No more decade-long wait: India eyes stealth 5th-gen stealth drone fighter to strike enemy air defences and save pilots' lives India’s Defence Research and Development Organisation (DRDO) is conducting trials of the indigenous Kaveri jet engine in Russia, with plans to use it in an upcoming Indian long-range Unmanned Combat Aerial Vehicle (UCAV), defence officials told ANI. The engine is in the final stages of testing, with around 25 hours of trials remaining. These remaining trials depend on the availability of test slots provided by Russian authorities. Officials confirmed the Kaveri engine is being considered for the indigenous UCAV project currently in development. CATS Warrior Hindustan Aeronautics Limited (HAL) is developing Combat Air Teaming System (CATS) Warrior, a fifth-generatio...

  Credit: (Ziteng (Andy) Wang ,  Astronomers have identified a  repeating radio signal  that is also emitting  X-rays , a first-of-its-kind observation that may point to an entirely new class of astronomical objects. The object, named  ASKAP J1832-0911 , was detected using the Australian Square Kilometer Array Pathfinder (ASKAP) and the  Chandra X-ray Observatory , and the discovery was published in the journal  Nature . Known as a long-period radio transient (LPRT), this source emits radio bursts every 44 minutes, lasting about two minutes each. Unlike anything seen before, this cosmic beacon is forcing scientists to reconsider what they know about neutron stars, white dwarfs, and the potential for entirely new astrophysical models. First Detection Across Such Wide Wavelengths ASKAP J1832-0911 stands out not just for its periodicity but for being the only known LPRT to emit both  radio waves and  X-rays  in sync. Most similar sourc...

  NH 48 traffic NH 48 connects Delhi, Gurgaon and Dwarka. (Photo: Archive) A 2.5-km tunnel on the Delhi stretch of Dwarka Expressway, connecting Dwarka to the Delhi-Gurgaon Expressway, is set to open to traffic on Thursday. Initially, the tunnel will operate daily from 12 pm to 3 pm on a trial basis to manage peak afternoon traffic, the Gurgaon traffic police said. Two-wheelers, three-wheelers, water and gas tankers, tractors with trolleys, and slow-moving vehicles are barred from the tunnel during this phase. Once fully open, the stretch is expected to ease travel to the Delhi Airport from Gurgaon, Manesar, Sohna, and Jaipur. The National Highways Authority of India (NHAI), along with Delhi and Gurgaon traffic police, had conducted a joint inspection on Tuesday, approving the limited-time opening. A spokesperson for the Gurgaon traffic police stated that authoritie...

  Lockheed to Boeing: How India’s Operation Sindoor may loosen the grip of US defence giants India’s growing military success, especially evident in recent operations like Operation Sindoor, should serve as a sharp warning to the United States. While India innovates quickly and builds cost-effective, scalable warfighting models, the US remains trapped in slow, outdated Cold War frameworks. The contrast is stark. India’s Pinaka rocket costs less than $56,000, compared to a US GMLRS missile priced at $148,000. India rapidly developed the Akashteer missile defence system at a fraction of the cost of US-made Patriot or NASAMS platforms. Even Ukraine’s use of Iran’s $20,000 Shahed-136 drone outpaces the US MQ-9 Reaper, which costs over $30 million. These examples highlight a fundam...

  US President Donald Trump and Elon Musk (R) speak before departing the White House on his way to his South Florida home in Mar-a-Lago in Florida on March 14, 2025. Billionaire Tesla CEO Elon Musk thanked US President Donald Trump as his time as a special government employee as part of the Department of Government Efficiency draws to an end, he said in a post on social media platform X on Wednesday. "As my scheduled time as a Special Government Employee comes to an end, I would like to thank President Donald Trump for the opportunity to reduce wasteful spending. The DOGE mission will only strengthen over time as it becomes a way of life throughout the government," Elon Musk posted on X. A White House official, who requested anonymity to talk about the change, confirmed news agency Associated Press that Elon Musk was leaving. “Elon Musk is leaving the administration is accurate and his off-boarding will begin tonight,” the official said. Elon Musk's 130-day mandate a...

  'Dragon has lost its teeth': Experts decode JN.1, the COVID variant that's making India nervous The fresh JN.1 wave of COVID-19 cases is sweeping through India, but experts say there's little reason to panic. While infections are up in states like Kerala, Maharashtra and Delhi, doctors stress that the current variant resembles the flu in severity, more nuisance than a nightmare. Dr Hemant Thacker, cardiometabolic specialist, summed it up in an interview to India Today TV, "So after entering the dragon phase, we have phase 2 return of the dragon, but this dragon has lost its teeth, has lost its energy."  He added that while there’s been an uptick in flu-like symptoms, “It’s the extreme fatigue that this new variant is bringing in.” Still, most patients recover quickly, unless they have pre-existing chronic conditions. Echoing the sentiment, Dr S Swaminathan, Head of Infectious Diseases at Gleneagles Hospital, said the virus never truly went away; it has si...
