NASA Warns Of Massive Solar Storm That Could Trigger Blackouts
NASA has issued a warning about heightened solar activity in the coming days, cautioning that intense solar storms may disrupt communications, navigation systems, and even power grids on Earth. The alert follows the strongest solar flare of the year, captured by NASA's Solar Dynamics Observatory.
The powerful X2.7-class solar flare erupted from a newly active sunspot, AR4087, and peaked on May 14, causing temporary radio blackouts across Europe, Asia, and parts of the Middle East. According to the US-based National Oceanic and Atmospheric Administration (NOAA), the high-frequency communication outages lasted nearly ten minutes in some regions.
NASA and the NOAA Space Weather Prediction Center are closely tracking this active solar zone, which continues to release powerful radiation bursts. The agency has warned that further flares could impact astronauts, satellites, and Earth-based technologies, including GPS systems, aviation communication, and electrical infrastructure.
Vincent Ledvina, a prominent aurora expert, said the situation is becoming "intense" as the active region rotates into full view of Earth. "This same sunspot just produced an M5.3 flare a few hours ago. What does it have planned next... we'll have to wait and see," he wrote on X (formerly Twitter).
The Sun is currently nearing the peak of its 11-year solar cycle - known as the solar maximum - when such powerful eruptions become more frequent. The UK Met Office said these flares could produce visible auroras in parts of the UK and Ireland around May 22, though such stunning displays are also indicators of underlying geomagnetic disturbances.
Solar flares are sudden bursts of radiation triggered by magnetic energy buildup in the Sun's atmosphere. An X-class flare - the most intense type - can significantly affect the Earth's ionosphere, interrupt satellite signals, and pose risks to space missions.
Should the public be concerned?
Experts say there is little cause for alarm among the general public, but sectors reliant on satellite navigation, aviation, and maritime operations are advised to remain alert to potential disruptions.

AI May Reduce World Population To 100 Million By 2300, Expert Warns: "Going To Be Devastating"
Earth could be left with only 100 million people by the year 2300, down from the current estimated population of eight billion, owing to artificial intelligence (AI) becoming omnipresent, a US-based tech expert has predicted. Subhash Kak, who teaches computer science at Oklahoma State University in Stillwater, Oklahoma, made the doomsday prediction, claiming that the population collapse will occur not due to Terminator-style nuclear holocaust but rather through AI replacing our jobs. 'It's going to be devastating for society and world society. I think people really don't have a clue," said Mr Kak, as per the New York Post. 'Computers or robots will never be conscious, but they will be doing literally all that we do because most of what we do in our lives can be replaced,' he added. The 'Age of Artificial Intelligence' author believes that birth rates will plunge as people will be reluctant to have kids who are destined to be unemployed. Without people making babies, the global population will suffer an apocalyptic blow. 'There are demographers who are suggesting that as a consequence, the world population will collapse, and it could go down to as low as just 100 million people on the entire planet Earth in 2300 or 2380,' he warned. Mr Kak cited the example of Europe, China, Japan and South Korea where the population decline has been prominent in recent years, to back up his claim. 'Now, I'm not saying that these trends will continue, but it's very hard to reverse them because a lot of people have children for a variety of reasons," he said. AI and jobs Mr Kak's sentiment of AI taking away jobs has been echoed by Anthropic CEO Dario Amodei, who recently claimed that 50 per cent of entry-level white-collar jobs could be eliminated within the next five years. "We, as the producers of this technology, have a duty and an obligation to be honest about what is coming. I don't think this is on people's radar," said Mr Amodei, adding that governments across the world were downplaying the threat. "Most of them are unaware that this is about to happen. It sounds crazy, and people just don't believe it." Mr Amodei said the US government had kept mum on the issue, fearing backlash from workers who would panic or that the country could fall behind in the AI race against China.

Why a seat for Shukla on Axiom-4 is a big moment for India's space programme
Four decades after Rakesh Sharma became the first Indian to travel to space, Shubhanshu Shulka, a 39-year-old Indian Air Force officer who is in the final leg of his pre-launch quarantine at the Kennedy Space Centre in Florida, will on Sunday, June 8, pilot a Dragon spacecraft that will take him, and three others, to the International Space Station (ISS), about 400 km from the Earth. Shukla, who is set to be the first Indian to step on to the ISS, will spend two weeks carrying out various experiments and studies in space. Though India or the Indian Space Research Organisation (ISRO) has had little role to play in the planning and execution of the mission — apart from securing a seat for an Indian on the spacecraft — Shulka's journey couldn't have come at a better time for the country's space programme as it prepares for Gaganyaan, India's own human spaceflight. The Dragon spacecraft, as well as the Falcon 9 rocket that will launch it into space, are built by Elon Musk-owned SpaceX, one of the biggest private space companies in the world. The mission is being operated and managed by Axiom Space, a nine-year-old private entity focused on commercial spaceflight services. The US space agency NASA is facilitating this mission as part of its broader initiative to encourage private operators to participate in commercial space transportation activities in Lower Earth Orbits. The four-member crew also has astronauts from Poland and Hungary – countries that, like India, are sending their nationals to space after 40 years — underlining the very diverse nature of participation in this mission. Shukla's space journey was not planned like this. He was selected and trained for Gaganyaan, India's maiden human spaceflight mission that was originally scheduled for 2022 but is now expected to happen in early 2027. In the meanwhile, in 2023, NASA and ISRO agreed to develop a 'strategic framework for human spaceflight cooperation', its immediate result being the inclusion of Indian astronauts in the Axiom-4 mission. Besides Shukla, Prasanth Balakrishnan Nair, another Indian astronaut selected for the Gaganyaan programme, also underwent advanced training for the Axiom-4 mission, and is on backup. ISRO has designed about 10 experiments for this mission. These include investigations into the effects of microgravity on muscle dysfunctions, and the physical and cognitive impacts of utilising computer screens in space. Another experiment would study the impact of spaceflight on the growth of six varieties of crop seeds. ISRO is also sending a few tardigrades to the ISS. These microscopic, water-dwelling organisms, also called water bears or moss piglets, are known to survive in extremely harsh environments. They are often studied in space to gain a better understanding of how life can survive in extraterrestrial conditions. These are the experiments that ISRO would have carried out on Gaganyaan if the mission had gone ahead of Axiom-4. Now it has the opportunity to conduct follow-up and more advanced experiments on its own missions. Besides, Shukla, who is the designated pilot of Space X's Dragon spacecraft, can pass on invaluable experience and feedback to his colleagues when they travel to space as part of Gaganyaan. 'The Axiom-4 mission being so close to the Gaganyaan flight is a very good opportunity for ISRO. Shuks (Shukla), being the pilot, will learn a lot from this mission, and those would be very relevant for India's other astronauts who are waiting. This mission is a very fortuitous and profitable learning experience for India. Even the ground scientists… they will get to practise how to interact with crew in space and the mission control team. All this would be invaluable to ISRO not just for Gaganyaan but also for the space station it plans to set up in a few years' time,' said Michael Lopez-Alegria, a famed US astronaut who holds the world record for the maximum number of spacewalks (10) and the maximum time spent in spacewalks (close to 68 hours). Lopez-Alegria, who commanded the previous mission of Axiom Space, named Axiom-3, was in Delhi earlier this month. While on the face of it Shukla's flight appears similar to the one undertaken by Rakesh Sharma 41 years ago, aboard the Soyuz T-11 spacecraft of the then Soviet Union, the contexts and objectives of the two are vastly different. 'Rakesh Sharma's spaceflight was largely a result of Indo-Soviet friendship and close relationship between the space agencies of the two countries. India's capabilities were very limited then, and a human spaceflight programme of its own was nowhere on the horizon. Though hugely important, and a big learning experience, there was little from Sharma's flight that ISRO could have utilised in practical terms. Shukla's spaceflight, on the other hand, is very different. It is not an isolated event. It feeds in directly into the Gaganyaan programme, and must be seen as one of the several preparatory steps that ISRO is taking in the run-up to its own human spaceflight mission,' said Mylswamy Annadurai, retired ISRO scientist who was the project director for the Chandrayaan-1 mission. Even Rakesh Sharma's flight was not supposed to be an isolated event. More such spaceflights with Indian astronauts were under discussion. But the accident of the US space shuttle Challenger in 1986 led to a reassessment of human spaceflight plans everywhere, and ended that initiative. Along with his two Soviet colleagues on the mission, Sharma carried out several space experiments during his flight. These resulted in ISRO getting access to important and novel data, though the space agency had little utility for them at that time. In 1984, India did not even have a decent rocket of its own. The only one it had, SLV-3, could barely carry 30-40 kg to Lower Earth Orbits. India's important satellites, like those of the INSAT series, were being launched from the United States. Four decades later, India's space capabilities are almost on a par with the best. It has already landed on the Moon, orbited around Mars, has an ongoing mission studying the Sun, is preparing to send humans into space and a mission to Venus, is building a space station of its own, and planning to land humans on the Moon. Shukla's spaceflight is much more than a joyride offered by a friendly country. 'There are many building blocks for a complex mission like Gaganyaan. ISRO has already carried out several test flights. Recovery missions have been done, reusable launch vehicles have been tested. Later this year, we will also have the first uncrewed flight in the lead-up to the actual crewed flight. All these are building blocks. Shukla's flight is also one of the building blocks. It is fully integrated with ISRO's immediate and long-term objectives, particularly the Gaganyaan mission,' Annadurai said. With days left for Shukla's space odyssey, Lopez-Alegria had an important advice for him: don't spend all your time only doing experiments. 'Enjoy the experience and find time to look at the Earth at every opportunity. I wish I had been told this during my first space trip,' he said. 'The astronaut's time in space is valuable with strict timelines drawn for tasks and scientific experiments. It is natural for an astronaut to be concerned about completing these tasks. But it is also important to soak in the experience and give a hard look to the wonder that is this universe,' he said.

Doctors develop new light-based treatment for rare eye infection
Hyderabad: Doctors at the LV Prasad Eye Institute in Hyderabad have discovered a new way to treat a rare but serious eye infection called acanthamoeba keratitis (AK) — a rare but serious eye infection that causes pain, redness, and can lead to vision loss. Tired of too many ads? go ad free now This infection is caused by amoeba found in places like water and soil. According to the study, it mostly affects people who wear contact lenses or come into contact with dirty water, such as those working on farms or using tap water to clean their lenses. Doctors tested a new light-based treatment called photodynamic therapy (PDAT-RB) and found it promising. The antimicrobial treatment uses a special dye called rose bengal, which is activated by light to produce powerful molecules that kill the infection. This, in turn, helped reduce inflammation in the eye. Rose bengal is a reddish-pink dye used in the diagnosis of eye conditions, which turned out to act as an effective photosensitising agent. Published in the United Kingdom-based Journal of Ophthalmic Inflammation and Infection, the study states that the most common cause of this disease is exposure of the eyes to contaminated water, especially in agricultural fields or washing contact lenses with tap water. An estimated 30-40% of patients suffering from AK require corneal transplantation, known as keratoplasty, on average. Despite that, many do not regain good visual acuity and require additional surgery. This study included 14 patients with AK infection. At first, they were given regular medicines to treat the infection. Then they received the new light-based PDAT treatment twice a week. The doctors used a solution with 0.1% rose bengal dye as part of the therapy. Tired of too many ads? go ad free now Doctors found that the treatment with the PDAT-RB reduced the need for corneal transplantation in 72% of the total patients with bacterial keratitis (inflammation of the cornea). Moreover, the infection was cleared in about 86% of patients within two to five months after the treatment. While most patients were suffering from almost complete vision loss before the treatment, only two of the total patients in the study required a corneal transplant to repair the damaged part. Although their vision improved after PDAT-RB therapy, they still had poor sight. On average, their vision went from total blindness to being able to see large objects or movement. Dr Gowtham Lakshminarayan, a research assistant scientist involved in the study, explained that the treatment works by creating powerful chemicals that destroy the harmful organisms in the eye. "The study suggests that if this treatment is used early, it can be a helpful and less-invasive (non-surgical) option to manage a severe eye infection that is usually hard to treat with regular medicines. The new treatment also shows that rose bengal is an effective photosensitiser and that early intervention with PDAT-RB treatment can yield promising results in the AK eye infection," he added.
