Human evolution mystery unlocked: How 100,000 years of isolation in southern Africa revealed hidden secrets of ancient DNA and our evolutionary history

New research reveals ancient humans in southern Africa lived in isolation for nearly 100,000 years. This led to unique genetic traits not seen in modern populations. These findings show human evolution was complex, involving multiple isolated groups. The study analyzed genomes from 28 ancient individuals, offering insights into early human diversity and adaptation.

What explains a grand-design spiral galaxy only 1.5 billion years after the Big Bang

The James Webb Space Telescope has discovered Alaknanda, a remarkably mature spiral galaxy existing just 1.5 billion years after the Big Bang. This well-organized structure, complete with a disc and arms, challenges existing theories about early cosmic evolution. Its existence suggests galactic formation may have been more efficient and rapid than previously believed, prompting a re-evaluation of cosmic timelines.

First humans reached Australia 60,000 years ago: How they arrived is finally clear

A groundbreaking genetic study confirms modern humans arrived in Australia approximately 60,000 years ago, settling a long-standing archaeological debate. Researchers analyzed thousands of genomes, revealing two distinct migration routes into the ancient continent of Sahul. This deep history aligns with Aboriginal oral traditions, showcasing advanced seafaring skills of early ancestors.

Physicists prove universe cannot be a simulation: New study debunks simulation hypothesis

Scientists at the University of British Columbia Okanagan say theyve found a mathematical limit that shuts down the Simulation Hypothesis entirely. Drawing on Gdels incompleteness theorem, their study argues that parts of reality cannot be generated by any algorithm, which means no computer, however advanced, could ever build a universe like ours. The obstacle isnt processing power. Its logic itself.

NASAs SWOT satellite captures first detailed look at 2025 tsunami, revealing mid-ocean waves and dispersive behaviour

A powerful 2025 Kuril-Kamchatka earthquake generated a Pacific-wide tsunami, captured by NASA's SWOT satellite. These unprecedented high-resolution images reveal complex, braided wave patterns, challenging the assumption that large tsunamis travel as non-dispersive waves. This discovery offers crucial new insights into mid-ocean energy distribution, promising to significantly improve future tsunami forecasting and hazard assessments.

Ancient giant that never shrank: Study shows Anacondas have been massive for 12 million years

Anacondas reached their enormous size about 12.4 million years ago and, unlike most other Miocene giants, have barely changed since. Fossils from Venezuela reveal that early anacondas were already as large as modern ones, defying climate cooling, habitat loss and new predators. Their enduring gigantism hints at remarkable resilience and ecological adaptability that future research now aims to explain.

ESA prepares to land on Enceladus: The hidden ocean world that may hold the first evidence of alien life

The European Space Agency is planning an ambitious mission to Saturn's moon Enceladus, launching in the 2040s. Utilizing an orbiter and lander, the mission will directly sample material from the moon's subsurface ocean via its geysers. Scientists aim to analyze these plumes for clues to extraterrestrial life, making Enceladus a prime target in the search for life beyond Earth.
