This extraordinary event is known as a sprite — or “farfadet” in French — one of the rarest forms of Transient Luminous Events (TLEs). Unlike typical lightning bolts that flash within the lower troposphere, sprites erupt much higher, in the mesosphere, at altitudes between 50 km and 80 km.
Telescopes allow scientists to analyse starlight passing through distant planets’ atmospheres, revealing clues about their chemical makeup and potential habitability. Over the past two decades, this work has fuelled remarkable discoveries.
China’s ambitions have surged since May 2021, when its Tianwen-1 mission made it the second nation after the U.S. to land on Mars. The Zhurong rover explored Utopia Planitia, paving the way for bigger goals.
The study details the devastating toll of the Fourth Global Coral Bleaching Event. The team assessed the impact of the bleaching event declared by the National Oceanic and Atmospheric Administration (NOAA) in April 2024, which caused widespread damage across the Great Barrier Reef.
Back in 2023, scientists were already puzzled by the Earth’s accelerating rotation, while some speculated that global warming and melting polar ice caps might be nudging the planet into a faster spin.
Researchers have bioprinted human islets designed to mimic the body’s own tissue structure, allowing them to integrate seamlessly under the skin. Tests show these lab-made islets stay functional for about three weeks, producing insulin in response to glucose levels without complications.
Radiation won’t be the worst killer. It’s famine. Thick smoke from burning cities could block sunlight, triggering global crop failures unlike anything humanity has ever faced.
On April 26, 1986, Reactor No. 4 at the Chernobyl Nuclear Power Plant exploded, blasting radioactive particles like cesium-137 and strontium-90 across Europe. More than 116,000 people were forced to evacuate a 30-kilometer Exclusion Zone, leaving behind a region scientists warned could remain hazardous for up to 24,000 years.
The new process marks a significant departure from traditional methods that rely on cyanide and mercury — substances notorious for polluting ecosystems and endangering human health.
More than 8 million people globally suffer from type 1 diabetes, a condition where the immune system destroys insulin-producing beta cells. Without these cells, blood glucose control becomes a constant battle, and patients must rely on insulin therapy to prevent serious complications.
Shubhanshu Shukla on Wednesday became the first Indian astronaut to travel to the ISS, joining three other crew members aboard Axiom Space’s commercial Ax-4 mission.
Group Captain Shukla, the designated pilot for the Axiom-4 mission, said that India is back in space again after 41 years.
The launch took place from Launch Complex 39A at NASA’s Kennedy Space Center in Florida at 12:01 PM IST, with SpaceX’s Falcon 9 rocket propelling the new Dragon spacecraft into orbit
SpaceX has confirmed that conditions are 90% favourable for liftoff on Wednesday, June 25, with all systems ready at NASA’s Kennedy Space Centre
This isn’t just about speed. The implications stretch across industries. From seamless HD streaming to improved satellite navigation and real-time communication for space missions, the technology has the potential to upend how data moves globally.
In a study that wired volunteers to EEG monitors as they wrote essays, the researchers found that using large language models (LLMs) like ChatGPT may do more than just help or hinder productivity — it might actually dull the brain’s cognitive muscle over time.
This marks the seventh postponement of the highly anticipated private spaceflight, which was originally scheduled for Sunday, June 22. A new launch date has yet to be announced.
If successful, the Sunbird could exceed even the Parker Solar Probe — the current speed record holder — by reaching up to 805,000 km/h. That would mean Mars in 30 days, and Pluto in just four years.
Traditional cancer therapies aim to destroy tumor cells, often damaging nearby healthy tissue and triggering harsh side effects. Publishing their results in Advanced Science, the researchers outlined a method to steer cancer cells away from uncontrolled growth and back toward a differentiated, stable identity.
The discovery of HKU5-CoV-2 comes amid heightened global vigilance over emerging infectious diseases, a caution rooted in the collective trauma of the COVID-19 pandemic that claimed millions of lives. Since then, several viruses have triggered momentary alarm.
Developing nuclear fusion for practical energy use has long challenged researchers. Achieving the extreme conditions required — temperatures above 100 million degrees Celsius — and sustaining them without consuming more energy than produced has remained elusive.
