Alcohol has a habit of leaving the body drier than it started. By interfering with hormones that regulate water balance, it increases fluid loss even as it’s being consumed, while its breakdown in the liver adds further strain. The result is thirst, headaches and fatigue that feel familiar to anyone who’s overdone it. Understanding the biology helps explain why simple measures, food, water and time, make a real difference.

ISRO's ambitious BlueBird-6 satellite launch, a significant Indo-US collaboration, is now set for December 21, 2025, after a slight reschedule. This massive satellite, featuring a large phased array antenna, promises direct-to-device broadband for underserved global regions, marking a leap in communication technology and showcasing India's prowess in complex space projects.

A groundbreaking AI model, GenCast, is revolutionizing weather forecasting by generating rapid, probabilistic global predictions for up to 15 days. Unlike traditional methods, it captures uncertainty and offers multiple plausible weather scenarios, outperforming current leading systems. This advancement promises more accurate, timely, and valuable insights for critical decisions in energy, disaster management, and finance worldwide.

Western Washington is grappling with devastating floods following relentless rain, amplified by powerful atmospheric rivers. These moisture-laden sky rivers, coupled with the region's mountainous terrain, unleashed extreme rainfall. Back-to-back storms saturated the ground, overwhelming rivers and leading to widespread inundation. Climate change is intensifying these events, increasing flood risks.

A Vancouver-based dermatologist, Dr Katie Beleznay, board-certified in both Canada and the US demonstrated how Botox works by injecting only one side of her husband Ben’s face. The controlled experiment showed, in real time, how neuromodulators soften lines, relax specific muscles and subtly change symmetry. Her video demystified a treatment often associated with extremes, offering a clear, practical look at its real effects.

A YouTuber’s decision to slip a GoPro into an air fryer, briefly, at low heat, offered thousands a rare look inside a kitchen staple we rarely question. The short clip, showing the fan and coil in quiet action, surprised viewers who realised they’d never actually seen how the device works. A simple, safe demonstration answered a very everyday curiosity.

Scientists at Radboud University say the universe will fade out far sooner than once believed, not in 10¹¹⁰⁰ years, but in roughly 10⁷⁸. Their calculations build on Stephen Hawking’s idea that black holes slowly evaporate, extending the process to neutron stars and white dwarfs. As these final stellar remnants dissolve, all luminous matter eventually disappears, marking the universe’s theoretical end.

Scientists now think the universe may be filled with tiny “primordial” black holes, relics from the first moments after the Big Bang, drifting through Earth by the thousand each year and passing through our homes and bodies without leaving a trace. These minuscule singularities may even be the missing dark matter, a possibility that could reshape how we understand the universe’s hidden mass.

Researchers are exploring the idea that one hemisphere of Earth, dominated by the Pacific Ocean, is losing internal heat faster than the continental side. This phenomenon, driven by differences in crust thickness and composition, has been shaping plate tectonics and volcanic activity over millions of years. The uneven cooling provides insights into Earth's long-term geological evolution and mantle circulation patterns.

Tech mogul Elon Musk has weighed in on UFO sightings, asserting that neither he nor SpaceX has encountered any evidence of alien visitors. He suggests most unexplained aerial phenomena have terrestrial origins, like advanced military projects or mundane objects. While acknowledging the ongoing search for extraterrestrial life, Musk emphasizes the need for concrete proof over speculation.

The Kola Superdeep Borehole was the USSR’s bold attempt to probe Earth’s crust during the Cold War, drilling over 12 km down for pure science. Engineers battled extreme heat, collapsing rock and soaring costs before abandoning the effort. Yet the project reshaped geology, revealing unexpected heat, deep fluids and ancient fossils beneath an ordinary Arctic manhole.

A 27-year-old woman with complete uterus didelphys used Reddit’s AMA to explain life with two uteruses, two cervixes and a divided vaginal canal, from painful periods and “two tunnels” to how her body handled pregnancy. She answered strangers’ questions with humour and clarity, while medical experts note the condition affects just 0.3% of people and can complicate fertility and menstruation.

Urban air travel is becoming a reality. NASA is creating advanced systems to manage air taxis and drones safely. These tools will coordinate flights, prevent collisions, and ensure smooth operations. Simulations show these plans can handle busy city skies. This work prepares for a future where air taxis and drones are common in cities.

NASA astronaut Jonny Kim has returned to Earth after an eight-month mission aboard the International Space Station. He conducted vital research in areas like bioprinting and robotics, contributing to advancements in medicine and future space exploration. The mission highlights the ISS's crucial role in scientific discovery and preparing for deeper space travel.

Prepare for a rare celestial spectacle as the longest total solar eclipse in a century occurs on August 2, 2027. For an unprecedented 6 minutes and 23 seconds, the Moon will completely obscure the Sun, plunging parts of North Africa, the Middle East, and the Indian Ocean into midday darkness. India will experience a partial eclipse during this extraordinary event.

On August 2, 2027, Saudi Arabia will witness the longest solar eclipse in 100 years, with the Moon blocking the Sun for over six minutes. The eclipse will also pass across North Africa and southern Spain. Daylight will fade to twilight, and the Sun’s glowing corona will shine around the Moon, offering observers a rare, breathtaking celestial spectacle.

Ever since interstellar visitor 3I/ATLAS entered view in July, its strange behaviour, shifting colours, erratic motion, a puzzling 16.16-hour “heartbeat,” has fuelled both scientific curiosity and speculation. Now, NASA astrochemist Martin Cordiner’s team has detected unusually abundant methanol and hydrogen cyanide in its plume, chemicals linked to life’s origins. Harvard’s Avi Loeb says the new data only deepens the mystery.
