NASA’s Bennu asteroid holds secrets of life: Discovery of sugars, mysterious space gum, and ancient supernova star dust

Bennu asteroid samples returned by NASA's OSIRIS-REx mission reveal life's building blocks, including sugars like ribose and glucose. Scientists also found a unique nitrogen-rich polymer, offering clues to early life's chemical origins. The asteroid's high concentration of supernova dust sheds light on its formation environment and the distribution of presolar materials in our early solar system.

Bengaluru startup first Indian firm to get US-FDA Class II nod for medical air cleaners

Bengaluru startup first Indian firm to get US-FDA Class II nod for medical air cleaners

Bengaluru-based Biomoneta has achieved a significant first, becoming the inaugural Indian healthtech firm to secure US-FDA 510(k) Class II clearance for its innovative medical air-cleaning device. This breakthrough, powered by their unique ZeBox technology, promises to revolutionize hospital infection control by effectively eliminating airborne pathogens, including SARS-CoV-2, paving the way for its deployment in US healthcare facilities.

Men are puzzled by the ‘stitch line’ running down the scrotum: Here’s what it actually is

Men are puzzled by the ‘stitch line’ running down the scrotum: Here’s what it actually is

Many men eventually discover a seam-like line on their scrotum and wonder whether it’s a scar, or something abnormal. In fact, it’s completely normal and medically known as the scrotal raphe, a developmental remnant from early fetal life. Health experts explain how, during embryonic development, genital tissue fuses under the influence of hormones, leaving this visible line, a harmless anatomical marker we all began with.

Scientists used Hollywood movies to hack the human brain and they found something wild

Scientists used Hollywood movies to hack the human brain and they found something wild

Researchers are using Hollywood films in brain-scanning studies, revealing that viewers' brains synchronize during emotionally charged scenes. This approach captures genuine, immersive reactions, offering insights into empathy, anxiety, and how the brain constructs and predicts the world. The findings hold potential for personalized mental health treatments and understanding narrative impact.

‘Miniature-lightning’ detected on Mars: Nasa rover makes rare discovery— new study explains

NASA's Perseverance rover has detected 'mini-lightning' on Mars for the first time, capturing faint crackles from dust-driven electrical discharges during storms. These tiny, centimetre-scale sparks, unlike Earth's lightning, were recorded by the rover's microphone, offering compelling evidence of atmospheric electrical activity on the Red Planet. Researchers are eager for further confirmation.
