A huge fireball dashed across the skies of western Japan, shocking residents and dazzling stargazers, though experts said it was a natural phenomenon and not an alien invasion. Videos and photos emerged online of the extremely bright ball of light visible for hundreds of miles shortly after 11.00pm local time (1400 BST) on Tuesday. “A white light I had never …

Scientists are calling attention to an extremely common health problem that’s been making astronauts uncomfortable: sinus issues. Researchers from Houston Methodist hospital’s Department of Otolaryngology – Head and Neck Surgery reported the results of their recent study that probed whether astronauts experience sinonasal issues, which include common symptoms such as nasal congestion and pressure or pain in the face, while …

NASA’s acting Administrator Sean Duffy says the agency will step back from climate science to focus on space exploration — highlighting a growing shift in the agency’s overall mission. The remarks echo President Trump’s NASA budget proposal, which seeks steep cuts to NASA’s Earth science initiatives, potentially putting several key missions at risk and raising concerns among researchers about gaps …

Insects are more influential than we realize By showing that ant- and termite-based diets evolved repeatedly, the study highlights the overlooked role of social insects in shaping biodiversity. “This work gives us the first real roadmap, and what really stands out is just how powerful a selective force ants and termites have been over the last 50 million years, shaping …

An automated data-sharing system co-developed by SpaceX and American radio astronomers promises to protect radio telescopes around the world from disruptive interference from satellites in low Earth orbit (LEO). Big constellations such as SpaceX’s Starlink bring high-speed internet to people in remote, under-connected areas. But they also stain optical telescope images with streaks and disrupt observations by radio telescopes — …

The rarest whale in the world is the spade-toothed whale (Mesoplodon traversii), with only seven confirmed specimens to date since first reported in the 1800s, and nobody’s ever seen one alive. All but one of them have been reported in the seas around New Zealand. Last December saw the first-ever dissection of one after it washed ashore on New Zealand’s …

It’s surprising because they would be the only organisms on Earth to do this. There are many metabolic processes that go in the forward direction and the reverse direction. That is something that life uses quite a bit just to be more efficient with our enzymes. But the idea that your respiration — what you breathe, what you get energy …
