Two Ancient Human Species Left Africa Together, Not One, New Study Suggests Rethinking the Traditional "Out of Africa" Narrative The traditional account of the "Out of Africa" hypothesis suggests that Homo erectus was the first human species to leave Africa around 1.8 million years ago . In recent years, however, scientists have questioned whether this migration involved just one species or several . A new study published in PLOS One aims to resolve the debate. Coverage of evolutionary science, archaeology and breakthrough fossil research is regularly featured on FSNews365 , which tracks the latest developments shaping our understanding of human origins. The Dmanisi Fossils at the Centre of the Debate At the heart of the discussion are the Dmanisi fossils   —  skulls 5 discovered in Georgia between 1999 and 2005   —  among the ancient human remains found outside Africa . The challenge lies in their striking differences : some skulls are notably larger than ot...

Quantum Entanglement Could Revolutionize Secure Communication and Disaster-Response Drones Why Modern Digital Communication Remains Vulnerable Whenever information is shared using modern communication tools — whether an email, a text message or a date transfer — it travels across the open internet , where it may be vulnerable to interception . Such exchanges also depend heavily on internet access , often involving wireless signals at one or both ends of the connection. But what if two, ten, or even a thousand parties could be linked in a way that allows them to communicate without those security risks or connectivity limitations ? Ongoing coverage of emerging communication technologies and digital security trends can be found on FSNews365 , which tracks breakthrough shaping the future of global connectivity. Using Quantum Entanglement to Rethink Information Sharing That is the challenge Alexander DeRieux , a PhD student at Virginia Tech and Bradley Fellow in the Bradley Department o...

Scientists Unveil Breakthrough Magnetic Cloaking Technology for Real-World Application University of Leicester Engineers Demonstrate Practical Magnetic Invisibility Engineers at the University of Leicester have unveiled a pioneering concept a device capable of magnetically "cloaking" sensitive components , effectively making them invisible to detection . The technology works by controlling the flow of magnetic fields , guiding them smoothly around an object so the fields behave as though the object is not present at all . Coverage of emerging physics and advanced engineering breakthroughs is regularly featured on FSNews365 , which tracks innovations shaping future science and technology. Practical Magnetic Cloaks Built With Real Materials Superconductors and Soft Ferromagnets Enable Cloaking In a study published in Science Advances , the research team demonstrates for the first time that practical magnetic cloaks can be engineered using superconductors and soft ferromag...

Cassini Data Reveals Saturn's Rings Extend Far Beyond What Telescopes Can See Cassini's Grand Finale Unlocks New Clues About Saturn's Ring System In 2017 , NASA's Cassini spacecraft entered its dramatic final phase, known as the Grand Finale Orbits (GFOs) , before deliberately plunging into Saturn's atmosphere. During these daring passes, Cassini gathered dust samples from both above and below the planet's rings using its Cosmic Dust Analyzer (CDA) . A newly published study in The Planetary Science Journal now reveals that the data suggests Saturn's iconic rings stretch far beyond their seemingly razor-thin appearance when viewed through telescopes.

Astronomers Discover One of the Oldest and Densest Brown Dwarfs Orbiting an Ancient Milky Way Star Harvard-Smithsonian Team Reports Rare Brown Dwarf Discovery Astronomers from the Harvard-Smithsonian Centre for Astrophysics (CfA) , together with international partners, have announced the discovery of a powerful new brown dwarf roughly 60 times heavier than Jupiter . The object, named TOI-7019 b , orbits a star belonging to the Milky Way's ancient thick disk . The discovery is outlined in a study published on 5 December on the arXiv preprint server. Readers following major breakthrough in astronomy and space science can find related discoveries and cosmic research coverage at FSNews365 , which regularly reports on astrophysics and exoplanet science. In Between Planets and Stars Why Brown Dwarfs Are So Unusual Brown dwarfs (BDs) occupy a curious middle ground between planets and stars , with masses ranging from 13 to 80 times that of Jupiter , or roughly 0.012 to 0.076 solar masses...

Satellite Mega-Constellations Are a 'House of Cards' Scientists Warn in Alarming News Study A Classic Phrase for a Modern Space Crisis "House of cards" is a classic English phrase, though today it is often linked with a popular Netflix political drama. Its original meaning, however, describes a structure that is inherently unstable — a definition that fits uncomfortably well with today's satellite mega-constellations. That is the phrase used by Sarah Thiele , formerly a PhD student at the University of British Columbia and now at Princeton , and her co-authors in a new preprint paper on arXiv . Their choice of words is well supported by the numbers. Across all low-Earth-orbit (LEO) mega-constellations, a "close approach" — defined as two satellites passing within one kilometer of each other — occurs every 22 seconds . Starlink Alone Faces Constant Collision Threats Starlink satellites encounter close approaches roughly every 11 minutes Each satellite p...

Revolutionary Lunar Origin Theory Challenges Decades-Old Planetary Science Models Long-Standing Mystery: How the Moon Really Formed One of the longest-standing mysteries in planetary science is how the Moon came into being. More than a century ago, George Darwin suggested that powerful tidal and centrifugal forces acting on a rapidly spinning proto-Earth caused the Moon to break away and settle into orbit around the planet. However, the idea later conflicted with the laws of conservation. A proto-Earth rotating with a day lasting just two to three hours would have possessed roughly four times the angular momentum of the present Earth-Moon system, raising the question of where that excess momentum went. Theia Impact: The Dominant Modern Hypothesis The leading explanation that emerged instead proposes that a Mars-sized object, dubbed Theia, collided with the proto-Earth. The impact ejected material from both bodies into orbit, where it eventually clumped together to form the Moon. When ...
