In the deep desert of Peru, a series of geometric stone corridors at Machu Picchu seem to align with solstices so precisely that some researchers joke they look like “time machines in stone.” Thousands of miles away, in the American Southwest, spiral rock carvings appear to track solar and lunar cycles over centuries, as ...
Space science loves a good mystery, but some cosmic riddles have proved stubbornly resistant to explanation even in 2025. Powerful telescopes, gravitational-wave detectors, and AI-driven surveys have turned the night sky into a data firehose, and yet the universe keeps serving up signals that do not fit our neat theoretical boxes. From invisible matter ...
The more neuroscientists learn about the human brain, the stranger it becomes. Powerful scanners can track blood flow in real time, algorithms can decode rough shapes from neural activity, and yet some of the most basic questions about how we think, feel, and decide remain stubbornly unanswered. The brain is less a clockwork machine ...
Arctic sea ice is disappearing at an alarming rate due to climate change, with scientists predicting the first ice-free summer could occur before 2030. In response, researchers are testing innovative technologies to slow ice loss and potentially regrow Arctic sea ice, raising questions about the feasibility and ethics of climate intervention. The Technology Behind Ice ...
Indigenous Amazonian shamans identified the specific combination of two plants required to make ayahuasca active orally – a pairing that stands as what may be one of the most unlikely discoveries in the history of human botany, given there are roughly 80,000 plant species in the Amazon – Image for illustrative purposes only (Image credits: ...
Women’s sense of smell is roughly 50% more sensitive than men’s on average, and the gap widens during pregnancy to a degree that some evolutionary biologists think is a defence mechanism for the fetus – Image for illustrative purposes only (Image credits: Pixabay) Walk into any well-equipped smell laboratory and the pattern emerges quickly: women, ...
The clearest indicator of whether a person has aged well into their seventies is not health, wealth, or relationships. It is whether they have continued to be surprised by things. – Image for illustrative purposes only (Image credits: Unsplash) Many people reach their seventies and beyond with solid health routines, financial plans, and close family ...
Every time we think we’ve pinned down how the universe works, reality pulls a plot twist worthy of a science-fiction epic. Telescopes peer deeper into space, quantum experiments probe smaller scales, and brain scanners map living thought – yet the biggest questions stay stubbornly out of reach. Cosmologists, particle physicists, and philosophers of mind ...
Female brains have measurably more connections between the two hemispheres, and male brains have more connections within each hemisphere – and neuroscientists still argue about whether this explains anything or nothing at all – Image for illustrative purposes only (Image credits: Unsplash) Parents, teachers, and clinicians routinely make judgments about a child’s likely strengths or ...
Sydney – For years, the notion of a planet circling two stars at once has felt like pure science fiction, yet it now stands on firmer observational ground. A research group at the University of New South Wales has applied a fresh detection approach to archival data and identified 27 additional candidates for these unusual ...
