Ahmedabad: The National Eligibility cum Entrance Test (
NEET-UG
) was marred by
biometric authentication problems
at several examination centres in the city on Sunday, causing significant delays and distress among candidates. Around 85,000 candidates took the exam across the state. Some centres, equipped with limited biometric systems, forced students to wait for some time before they were allowed to proceed to their exam halls.
Multiple centres reported technical glitches in the biometric attendance system, with many students being initially denied entry due to authentication failures, particularly those with outdated Aadhaar cards. The situation led to protests from concerned parents, necessitating police intervention at locations including LD Engineering College.

James Webb Space Telescope reveals first exoplanet with 'sand rain' and a growing 'sandcastle' companion, redefining planetary evolution
Source: NASA James Webb Space Telescope (JWST) has discovered something incredible. A far-off planetary system with gas giants that are packed with coarse silica, which is a space sand. The YSES-1 system , which surrounds a young star 300 light-years from Earth, consists of two planets, YSES-1 b and YSES-1 c, both of which have atmospheric sand clouds. The system is a mere 16.7 million years old, an infant in cosmic age that presents scientists with the unusual chance to watch planet formation and development unfold in real-time. These results may redefine the knowledge of the formation and evolution of planets, including those within our own solar system, over billions of years. NASA's James Webb Space Telescope detects 'sand clouds' made of silicates According to the study, silicate clouds, or sand clouds, consist of mineral grains such as pyroxene and forsterite, iron-containing compounds found in rocky planets and meteorites. They are more than a novelty in the atmospheres of exoplanets; they contain important clues about the chemistry and atmosphere of far-off worlds. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Buy Brass Idols - Handmade Brass Statues for Home & Gifting Luxeartisanship Buy Now Undo According to Italy's National Institute for Astrophysics (INAF) scientist Valentina D'Orazi, the silicates seen in these planets go through sublimation and condensation cycles just like water on Earth. These active cycles help the sand clouds stay suspended in the air, indicating sophisticated atmospheric transport and formation processes. JWST reveals silicates in both exoplanet atmospheres and formation disks Of the two gas giants, YSES-1 b is a still-growing planet that could someday be a large Jupiter analogue. It is encircled by a flattened cloud of material, a circumplanetary disk; a phenomenon common around young planet. The disk holds the planet-building blocks of its atmosphere, silicates, which fuel its growth. YSES-1 c, however, is already enormous, around 14 times as massive as Jupiter. Its atmosphere has a reddish color due to suspended silica, which sometimes rains down as sandy rain to the planet's center. This is the first direct detection of silicates not only in an exoplanet atmosphere but also in a circumplanetary disk. That makes this observation historic and also pivotal to the study of planetary science. How JWST made the discovery possible The James Webb Space Telescope was able to image these subtle details due to the extended orbits of the planets around their parent star. These were distances ranging from five to ten times the distance between the Sun and Neptune, and they enabled astronomers to view the planets without the blinding light of the star. With its sophisticated infrared equipment, JWST gathered high-resolution spectral information that, on analysis, showed the presence of silicate particles and their composition. Although such direct observation remains possible only for a few exoplanets at this time, it highlights JWST's unparalleled capability to observe in detail the atmospheres and environments of other worlds. JWST insights reveal how Jupiter and Saturn may have taken shape One of the most intriguing things about this discovery is what it implies about the early history of our own solar system. By looking at young exoplanets such as YSES-1 b and c, astronomers can deduce how gas giants such as Jupiter and Saturn might have formed and developed. "Examining these planets is like peeking into the history of our own planetary back yard," D'Orazi explained. "It confirms that young exoplanet atmospheres and the disks around them are key drivers of their final atmosphere composition." The researchers also highlighted the need for detailed atmospheric models to interpret the JWST's excellent data pointing to the telescope's continued role in pushing the frontiers of planetary science and exoplanet study. These historic findings were released on June 10 in the journal Nature and highlighted the same day during the 246th American Astronomical Society meeting in Anchorage, Alaska.

Atlantic's largest Great White Shark resurfaces near US coastline after months
Source: New York Post A record-breaking Great White Shark named Contender is making headlines as it journeys along the US East Coast, surfacing near a popular vacation region. Measuring an astonishing 14 feet in length and weighing approximately 1,653 pounds, Contender is the largest Great White Shark ever tagged in the Atlantic Ocean. According to the reports, the Great White Shark was first tracked in January 2025 by OCEARCH, a nonprofit research organisation dedicated to marine research. This massive predator was tagged off the Florida-Georgia coast, near Jacksonville. According to the New York Post reports, after nearly a month without signal, the shark recently resurfaced off Pamlico Sound in North Carolina, sending waves of excitement through the scientific community and ocean enthusiasts alike. Contender's movements mark a vital feeding stop during his seasonal migration northward, according to what the experts say. 14-foot Great White Shark Contender reappears after vanishing The Great White Shark nicknamed as Contender, is a 14-foot, 1,653-pound predator that was first tagged in January 2025 by OCEARCH, a leading nonprofit research organisation focused on large marine species. The shark was located roughly 45 miles off the Florida-Georgia coast, near Jacksonville. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Buy Brass Idols - Handmade Brass Statues for Home & Gifting Luxeartisanship Buy Now Undo After disappearing from trackers for almost a month, Contender resurfaced northward off Pamlico Sound in North Carolina. The absence was due to how its tracker functions; it only transmits location data when the dorsal fin breaks the surface of the water, making updates sporadic. Contender is estimated to be about 30 years old, placing it among the oldest documented Great White Sharks currently being monitored. According to Dr. Harley Newton, OCEARCH's chief scientist and veterinarian based in Ponte Vedra, Florida, this movement aligns with known migratory behaviour. North Carolina waters serve as key feeding stop for migrating great whites This deviation to North Carolina's coastal waters is believed to be a crucial feeding period. Experts suggest that this region offers an abundance of food that allows sharks like Contender to build energy reserves in preparation for a northward journey that could span over 1,000 miles. Dr. Newton added, 'We often observe tagged sharks lingering off the Outer Banks before continuing their migration. The availability of prey makes this area an important pre-departure refuelling site. ' How OCEARCH tags and tracks sharks The tagging process for Contender was extensive and carefully executed. Researchers captured the shark alongside their specialised research vessel, collected biological samples for further analysis, and fitted a SPOT (Smart Position or Temperature Transmitting) satellite tag to its dorsal fin. This SPOT tag allows real-time GPS tracking when the shark surfaces. Both scientists and the public can follow its movements through OCEARCH's Global Shark Tracker, an open-access digital platform. Role of sharks in marine conservation Data collected from Contender and other sharks play a vital role in marine conservation. By studying their migratory routes and behaviours, researchers can identify critical habitats that need protection. Great white sharks are apex predators and play an essential role in balancing marine ecosystems by regulating prey populations. However, they face growing threats from overfishing, habitat degradation, and the ongoing impacts of climate change.

Scientists warn we might be the last generation to see fireflies: Why are they disappearing?
It may not be too far in the future when we will only be left with Owl City's serenading song, and no fireflies in real life. At least, that's what the researchers and scientists are warning about. Raphaël De Cock, a firefly researcher, as reported by National Geographic, wrote his PhD thesis on larvae like the one he found as a child. And sadly, what's relatable is that, unanimously, we all see a lot fewer fireflies than we used to in our childhood. Experts confirm the same grim truth, saying there's scientific merit to that observation, as firefly species around the world are declining. Fireflies: Conjuring starry skies on Earth Fireflies are those enchanting insects that illuminate summer nights with their bioluminescent displays. They belong to the family Lampyridae, which includes more than 2,000 described species, many of which emit light. These soft-bodied beetles are commonly known as fireflies, lightning bugs, or glowworms due to their distinctive light production, primarily during twilight, to attract mates. The type species is Lampyris noctiluca, known as the common glow-worm of Europe. It is believed that light production in the Lampyridae initially originated as a warning signal to indicate that the larvae were distasteful. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like เทรดทองCFDsกับโบรกเกอร์ที่เชื่อถือได้| เปิดบัญชีวันนี้ IC Markets สมัคร Undo This ability to produce light was later adapted as a mating signal. Additionally, adult female fireflies of the genus Photuris have been known to mimic the flash patterns of the Photinus beetle to lure their males as prey. Although all known fireflies glow as larvae, only some species produce light in their adult stage, and the location of the light organ varies among species and between sexes of the same species. Fireflies have attracted human attention since classical antiquity; their presence has been taken to signify a wide variety of conditions in different cultures and is especially appreciated aesthetically in Japan, especially in Miyazaki films, where parks are set aside for this specific purpose. And sadly, those magical insects are rapidly disappearing from our landscapes. Recent studies indicate that we may be the last generation to witness their mesmerizing glow. However, understanding the reasons behind their decline is crucial for conservation efforts. Habitat loss : The vanishing wetlands and woodlands Fireflies are generally found in temperate and tropical climates, and they thrive in specific habitats, primarily moist environments like wetlands, marshes, and damp woodlands. These areas provide the necessary conditions for their larvae, which spend a significant portion of their lives in the soil or under leaf litter. Urbanization, agricultural expansion, and deforestation have led to the destruction and fragmentation of these habitats, making it increasingly difficult for firefly populations to survive and reproduce. Light pollution : The night sky's silent intruder Artificial light at night, or light pollution, has a profound impact on fireflies. Most firefly species rely on their natural bioluminescence for mating rituals. The glow from streetlights, billboards, and other artificial sources can interfere with these signals, leading to mating disruptions and declining populations. Studies have shown that light pollution is one of the fastest-growing threats to firefly conservation, outpacing even habitat loss in some regions. Pesticides: The fatal chemical warfare The widespread use of pesticides in agriculture poses a significant threat to fireflies. These chemicals not only kill fireflies directly but also reduce the populations of their prey, such as snails and slugs, which are essential for their larvae. Additionally, pesticides can contaminate water sources, further degrading the delicate ecosystems fireflies depend on. Climate change: Altering life cycles Climate change is altering the temperature and moisture levels of habitats, affecting the life cycles of fireflies. Warmer temperatures can lead to earlier or mismatched timing of mating seasons, reducing successful reproduction. Changes in precipitation patterns can also impact the availability of suitable habitats and prey, further stressing firefly populations. Conservation efforts: Protect the glow The decline of fireflies is a poignant reminder of the broader environmental challenges we face. Their disappearance signifies the degradation of ecosystems that support countless other species, including humans. It is imperative that we take collective action to address the factors contributing to their decline. Efforts are underway globally to protect and conserve firefly populations. Those initiatives include: Habitat restoration: Rehabilitating wetlands and woodlands to provide suitable environments for fireflies. Reducing light pollution: Implementing measures to minimize artificial lighting in critical habitats. Sustainable agricultural practices: Promoting the use of eco-friendly pesticides and farming techniques. Public awareness campaigns: Educating communities about the importance of fireflies and how to protect them.
