NASA warns! Massive 25-storey building sized asteroid is set to pass close to Earth on May 28 - know the speed, time and other key details
Asteroid 2025 JR is moving towards Earth on May 28
On 28 May 2025, Asteroid 2025 JR is set to pass by Earth at 8:40 am IST, which is about 250 feet (76 meters) across, a respectable size in space. It's an Apollo-class near-Earth object (NEO)—a class marked by asteroids that have orbits that intersect with Earth's orbit around the Sun. Being of this kind of orbital feature, these asteroids are kept under close watch for how much danger they could pose.
The asteroid travels at a staggering 40,800 km/h, a speed that, were it orbiting the Earth, would finish the journey in under an hour. While 2025 JR is not deemed a "potentially hazardous asteroid" because it is below the threshold diameter of 460 feet (140 meters), it is large enough that if it were to strike the Earth, the destruction would be devastating.

Asteroid 2025 JR potential risk
Should asteroid 2025 JR impact Earth, the destruction would be horrific. Moving at incredible velocity, the impact energy would be equivalent to a few nuclear bombs detonating in unison. This would destroy much, trigger huge explosions, and potentially result in large-scale loss of life.
One traditional historical analogy most often provided is the 1908 Tunguska asteroid or comet explosion in Siberia, where an asteroid or comet with a diameter of approximately 160–200 feet exploded in the air. The explosion flattened approximately 2,000 square kilometres of trees—a wider area than the city of Delhi—showing the destructive energy released by comparatively small space bodies.
How scientists track near-Earth objects
Asteroid tracking 2025 JR is a complicated process which engages the whole world. NASA's Centre for Near-Earth Object Studies coordinates the activity by collecting data from a variety of telescopes and radar stations across the globe. Amateur astronomers also participate by searching the sky for unidentified objects. This network assists researchers in forecasting near-approach and possible impact events more accurately. But despite all these developments, there are still numerous space rocks that are unknown, posing challenges to planetary defence constantly.

Make cell & gene therapies affordable, Prof AK Sood, principal scientific advisor (PSA) to Union government told researchers in Bengaluru
Bengaluru: "Innovations in cell and gene therapies are good, but work towards making them affordable," Prof AK Sood, principal scientific advisor (PSA) to the Union govt told researchers Thursday. But what are these therapies that Sood spoke about? They are cutting-edge medical treatments that aim to cure diseases at the source rather than just manage symptoms. Gene therapy fixes faulty genes. It's like correcting the instruction manual in our cells. And cell therapy uses specially prepared cells — often taken from the patient or a donor — to help the body heal, fight disease, or replace damaged cells. You Can Also Check: Bengaluru AQI | Weather in Bengaluru | Bank Holidays in Bengaluru | Public Holidays in Bengaluru These therapies are already being used to treat serious conditions like blood cancers and rare genetic diseases. But each treatment can cost lakhs or even crores of rupees, making them out of reach for most people. "Today, these therapies are extremely expensive — even in developed countries. If we want to make them widely accessible in India, we need a much larger and coordinated effort," Sood told the researchers and innovators at the India AMR Innovation Workshop held at C-CAMP here. He said the Centre is working on a dedicated "Cell and Gene Therapy Mission" that will bring together several ministries and departments. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Villas For Sale in Dubai Might Surprise You Dubai villas | search ads Get Deals Undo "Science and technology is one part. The real challenge is scaling up to reduce costs. We must also develop key chemicals ourselves to cut down on imports," he said, noting that IIT Bombay is already working on this. Citing ImmunoACT — a CAR-T cell therapy for cancer treatment that uses the patient's own immune cells to fight the disease — developed with govt support as a good example, he said private companies are now stepping in to take it forward and reduce costs further. Sood also said quantum computing could speed up the discovery of new drugs by quickly solving complex problems, helping scientists find medicines faster. "This could change the future of healthcare," he said. Pointing out that India lacks strong laws to stop over-the-counter sale of antibiotics, which is a major cause of antimicrobial resistance (AMR), Sood blamed fake doctors, easy access to antibiotics, and high consultation fees for irresponsible usage. Karnataka IT-BT secretary Ekroop Caur spoke about the rising danger of AMR, saying even people who don't misuse antibiotics can be affected because of what's happening in animals and plants. "That's why Karnataka launched a new AMR action plan this year." C-CAMP CEO and director Taslimarif Saiyed warned that AMR could lead to 10 million deaths a year if urgent action isn't taken.

With 7k women, Mumbai's KEM Hospital starts BMC's largest and most expensive clinical trial for breast cancer diagnosis
Mumbai: KEM Hospital has started its largest and most expensive BMC-funded trials with 7,000 women aimed as participants, which will potentially change how breast cancer is diagnosed at the hospital. The trial, which will last for 12 to 28 months, involves a small, portable device with a high-resolution thermal sensor powered by artificial intelligence. The hospital has also started a dedicated 15-bed ward for all breast-related ailments, 14 years after starting the city's first breast clinic at a civic hospital. Unlike traditional mammography, the machine in trial involves no physical contact or breast compression, eliminating the discomfort associated with X-ray-based screening. During the procedure, the patient is alone in a private room, seated at a fixed distance from the thermal imaging device with curtains for privacy. The exact costs were unavailable until press time, but hospital officials said this is the largest BMC-funded trial. The machine, developed by Bangalore-based NIRAMAI Health Analytix, costs Rs 50 lakh and has taken up residence free of cost at KEM Hospital as part of a clinical validation under BMC's startup incubation programme. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Esta nueva alarma con cámara es casi regalada en Florencio Varela (ver precio) Verisure Más información "We are moving forward with it only on the condition that the machine will remain at KEM Hospital if trials show favourable results," said Dr Shilpa Rao, associate professor at KEM's general surgery department, who is also the principal investigator for the trial. You Can Also Check: Mumbai AQI | Weather in Mumbai | Bank Holidays in Mumbai | Public Holidays in Mumbai She added that thermal imaging has been around since the 2000s, but it detects any source of heat, including infections and inflammation, which can lead to false positives. "This can result in unnecessary psychological distress and economic burden for patients," said Dr Rao. In this case, the machine uses AI to scan heat patterns on the chest, looking over 400,000 tiny temperature points to detect any unusual changes. The report comes back in 24 hours, and the algorithm produces a breast health score that tells doctors if it is malignant, benign, or requires further evaluation. Everyone taking part in the trial will get all three tests: a mammogram, an ultrasound, and the AI-powered scan. Doctors will then compare the results to see how well the new technology works. Dr Rao was also struggling to have a dedicated ward for breast treatment since 2010. "Perhaps having a woman as a dean made the difference now," she said. KEM Dean Dr Sangeeta Ravat said, "The issue is very close to my heart, and breast cancer patients need a special ward as they are already immunocompromised. There were some problems; it couldn't happen before, but now they have been resolved," she said. Dr Varsha Kulkarni, Department Head of General Surgery, who was instrumental in having the ward up and running, said, "Women's health needs priority."

Mysuru school students to interact with astronaut Shubhanshu Shukla today
Mysuru: Students from Excel Public School in Mysuru will participate in a live interaction with astronaut Shubhanshu Shukla, who is currently stationed aboard the International Space Station (ISS) as part of the Axiom Space AX-4 mission. The event, scheduled for 3.47pm on Friday, will take place through the Amateur Radio on the International Space Station (ARISS) initiative, in coordination with the UR Rao Satellite Centre (URSC) in Bengaluru. This prestigious opportunity allows students to establish direct communication with the ISS using amateur radio frequencies, representing a significant application of STEM education. Licensed student HAM operators from Excel Public School, including Bhuvan PM, Namasyu A, Tanish Tejaswi MS, Pranav CN, Vishruth R, and Sanat Raj G, will represent the school during the ISS interaction. They will be guided by their mentor and Amateur Radio club custodian, Mahesh MB. This interaction is part of a global network of scheduled ARISS school contacts that aim to introduce young learners to space science, communications technology, and orbital research. In a joint statement, the students said, "As licensed student HAM operators, we have spent months learning the science behind radio communication, tracking satellites, and assembling and testing antennas. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Descubre si tienes derecho a la instalación gratuita de la alarma que arrasa en Argentina Verisure Más información Undo Being able to apply all of that by connecting with the ISS is an experience we never imagined we'd have at this stage in our learning journey. We are especially excited to ask questions we have always been curious about from life in space to the role of communication technology in such missions. " "This contact is the result of sustained effort by the students, from clearing their ASOC exams to building antennas and decoding signals from the ISS. It's a practical demonstration of what they've learned, and a moment they will carry with them for life," Mahesh said.
