An underwater volcano, Axial Seamount, located off the Oregon coast, is showing signs of renewed activity, with scientists predicting a potential eruption later this year or early 2026. Researchers have recorded increased earthquake activity and seafloor swelling, indicating magma accumulation.
A recent analysis by the World Weather Attribution group reveals that human-caused climate change intensified the deadly rainfall in early April across states like Arkansas and Kentucky. The storms, which triggered tornadoes and floods, resulted in at least 24 fatalities. Researchers found that climate change increased rainfall intensity by 9 per cent and made such events 40 per cent more likely.
The Global Space Exploration Conference 2025 in New Delhi achieved record attendance, yet NASA's absence due to budget cuts and internal transitions raised concerns. Despite India's successful hosting and the participation of numerous nations, NASA's non-attendance highlighted the impact of financial constraints on international space collaboration and discussions, impacting the agency's role in future space exploration.
India's ISRO successfully conducted a high-speed satellite rendezvous during its SPADEX mission, showcasing advanced orbital control and autonomous docking capabilities. This achievement, initially intended for satellite servicing, evolved into a demonstration of coordinated maneuvers, resembling a space-based dogfight. The mission underscores India's growing prowess in space security and its ability to protect its assets in orbit.
India's ambitious Gaganyaan mission, aiming to send humans into space, is now slated for the first quarter of 2027, announced Union Minister Jitendra Singh. Key test missions, including TV-D1 and TVAM, have paved the way, with TV-D2 planned for 2025. The mission emphasizes crew safety, orbital competence, and involves rigorous astronaut training.
A new NASA and Toho University study, utilizing supercomputers, projects Earth's habitability timeline, revealing the eventual demise of life due to the Sun's increasing heat. This gradual process, unfolding over billions of years, will drastically alter the atmosphere and ecosystems. While distant, the research emphasizes the need for preparation through technological solutions and space colonization to ensure humanity's survival.
Asteroid 2025 HY2, an Apollo-class asteroid, will pass Earth on May 7, 2025, at a speed of 48,904 km/h. Though passing at a distance of 6.8 million kilometres, it's a close call in cosmic terms. While not a direct threat, its size, similar to a Boeing 737, highlights the potential devastation of undiscovered asteroids.
Scientists at Southampton University have made a significant advancement. They have successfully simulated the 'Black Hole Bomb' theory in a lab. This theory, proposed in the 1970s, explores tapping into a black hole's rotational energy. The experiment involved a rotating cylinder and magnetic fields. The results showed energy changes based on relative rotation speeds.
Tim Friede, a former truck mechanic, intentionally subjected himself to numerous snakebites over two decades, aiming to develop immunity. His unusual experiment led to a breakthrough in antivenom research. Scientists discovered broadly neutralizing antibodies in Friede's blood, paving the way for a universal antivenom that could protect against various venomous snakes and save thousands of lives annually.
Freud didnt just invent psychoanalysis. He invented the modern notion of the self: that what we are is not just what we do, or say, or post on Instagram, but a bubbling cauldron of instincts, memories, and traumas buried beneath the surface. Born in 1856 in what is now the Czech Republic, Freud was a neurologist by training, but like all true revolutionaries, he broke his field before he built a new one.
SpaceX is set to launch a Falcon 9 rocket carrying Starlink satellites from Florida's Space Coast on May 6, 2025. The launch window opens at 8:22 p.m. EDT, offering a spectacular nighttime display visible from Jacksonville Beach to West Palm Beach. This mission aims to expand SpaceX's Starlink broadband constellation, providing global high-speed internet access.
The eruption of Mount Vesuvius in 79 AD buried Pompeii and Herculaneum, preserving Roman life in ash. Recent discoveries, including exotic animal bones, vitrified brains, erotic art, and children's graffiti, offer insights into Roman cuisine, trade, medicine, and culture. Ongoing excavations continue to reveal tragic stories and expand our understanding of this ancient civilization.
Recent discoveries have challenged previous assumptions about the space near Earth, revealing a potential population of undiscovered minimoons, some of which may be lunar debris. The identification of 2024 PT5, an asteroid-like object with lunar characteristics, supports this theory. These minimoons offer a unique opportunity to study the Moon's impact history and could serve as targets for future space missions.
Indian researchers from Shiv Nadar University have developed a bioinspired aluminium surface that repels water, resists corrosion and bacteria, and self-cleans using minimal water. Mimicking lotus leaves and insect wings, the eco-friendly process creates superhydrophobic and antibacterial surfaces ideal for marine, healthcare, and packaging industries. The innovation promises scalable, low-cost applications with support from CSIR.
A new study reveals North American bird populations are declining, especially in their traditional habitats, due to rapid environmental changes like climate change. Researchers analyzed vast eBird data using machine learning to pinpoint these trends. The study found that 97% of species face both population increases and declines, with 83% shrinking fastest in their most abundant areas.
A significant 7.4 magnitude earthquake struck off the southern coast of Chile and Argentina, prompting a tsunami warning. Chilean authorities initially ordered coastal evacuations in the Magallanes region, anticipating potential tsunami waves. Fortunately, the evacuation order was later lifted as no immediate injuries or damage were reported, though Argentina issued a localized evacuation order.
Human-induced climate change made the ultra-dry and warm conditions that fanned South Korea's deadliest wildfires in history this March twice as likely and more intense, researchers said Thursday. South Korea's deadliest wildfires were made much more likely by climate change, said Clair Barnes, a WWA researcher from the Centre for Environmental Policy, Imperial College London.
New Zealand faced severe weather conditions, prompting a state of emergency in Christchurch due to heavy downpours and river overflows. Wellington experienced destructive gales, leading to flight cancellations and warnings for residents to stay indoors. Heavy snow and large waves impacted other regions, causing power outages and disruptions to daily life, with the storm expected to ease on Friday.
In drought-stricken Iraq, farmers like Hadi Saheb are drilling wells to tap into groundwater reserves, enabling them to cultivate desert lands and increase wheat production. While this government-backed initiative boosts food security, experts warn that unsustainable groundwater extraction threatens to deplete this vital resource, mirroring past experiences in neighboring countries and raising concerns about long-term water availability.
In Chile's ancient rainforest, the 'Gran Abuelo,' a 5,400-year-old tree, faces a new threat from a proposed highway. Scientists warn the road will increase the risk of wildfires and endanger the Alerce trees, which are vital for climate research. Researchers are working to protect this ancient tree and its surrounding ecosystem.
The UK government and Italian energy company Eni Thursday announced a deal to create a major carbon capture and storage network to store millions of tonnes of CO2 beneath the Irish Sea. Eni plans to store 4.5 million tonnes of CO2 per year, a quantity that could rise to 10 million after 2030, equivalent to the emissions of four million cars.
A new study estimates that the world's largest corporations have caused $28 trillion in climate damage, aiming to hold companies accountable like tobacco giants. The research identifies 111 companies, with the top ten fossil fuel providers, including Saudi Aramco and Gazprom, responsible for over half of the damage.
Indian Institute of Astrophysics researchers have revisited the ultra-diffuse galaxy, NGC 1052-DF2, challenging previous assumptions about its dark matter deficiency. The study suggests the galaxy possesses a 'cored' dark matter halo, unlike earlier 'cuspy' models. This new model indicates a more evenly spread dark matter distribution, potentially aligning NGC 1052-DF2 with standard galaxy formation theories.
