4.5-billion-year-old traces of proto-Earth discovered could rewrite our planets origin story
MIT scientists have discovered ancient rock samples from Greenland, Canada, and Hawaii exhibiting a rare potassium-40 deficit. This chemical signature suggests these rocks are remnants of proto-Earth, predating the giant impact that formed the Moon. The findings challenge previous assumptions about the early Earth's complete remelting and offer a glimpse into the solar system's initial chemistry.
Why do we lose our appetite when were sick? Science explains what happens inside your body
When you're sick, your immune system releases cytokines that signal your brain to suppress hunger, redirecting energy to fight infection. This natural loss of appetite, coupled with fever and inflammation, makes food less appealing. While mild appetite loss aids recovery, staying hydrated and eating light meals is crucial until your body heals.
The International Space Station is set for a controlled deorbit by 2030. This orbiting laboratory, a testament to global collaboration, has hosted thousands of experiments, significantly advancing science and technology. NASA is now transitioning to privately operated space stations to maintain human presence in orbit, fostering a new era of space exploration.
Google for DNA: Scientists create the worlds first and fastest genetic search engine
Scientists at ETH Zurich have unveiled MetaGraph, a revolutionary tool dubbed 'Google for DNA'. This innovation allows rapid searches across vast genetic databases, overcoming the slow, resource-intensive methods previously used.

The real cause of depression may lie in just two brain cell types, scientists say
Scientists have pinpointed specific neurons and microglia, crucial for emotion and inflammation, as key players in depression. This breakthrough, using advanced brain tissue analysis, reveals disrupted gene activity in these cells. The findings offer a biological foundation for the disorder, paving the way for more targeted and effective future treatments for millions worldwide.
NASA's Artemis program is set to explore the Moon's south pole, a region of perpetual darkness holding clues to the solar system's formation. Missions will seek water ice and other frozen volatiles, potentially revealing how Earth acquired its water. This discovery could revolutionize space exploration, enabling lunar bases and Mars missions.
First-ever image captures two black holes orbiting each other
Scientists have captured the first image of two black holes orbiting each other in the quasar OJ287, confirming a long-held astronomical theory. Using radio telescopes, researchers detected particle jets from the 18-billion-solar-mass and 150-million-solar-mass black holes, locked in a 12-year orbit. This unprecedented observation offers a glimpse into binary supermassive black hole dynamics.
