A famous "oldest octopus" fossil has been exposed as a case of mistaken identity. Advanced imaging revealed hidden teeth showing it was actually related to a nautilus, not an octopus. The confusion came from decay that altered its shape before ...

Researchers have developed a cutting-edge technique that uses RNA "barcodes" to map how neurons connect, capturing thousands of links with single-synapse precision. The method transforms brain mapping into a sequencing task, making it faster and more ...

Scientists at Cornell University may be closing in on the long-sought "holy grail" of male contraception: a safe, reversible, nonhormonal method that completely halts sperm production. In a breakthrough mouse study, researchers used a compound called ...

Vitamin D levels in midlife may play a bigger role in long-term brain health than previously thought. In a study following nearly 800 people over 16 years, those with higher vitamin D levels in their 30s and 40s had lower levels of tau protein later ...

Scientists have finally uncovered the missing link in how our bodies absorb queuosine, a rare micronutrient crucial for brain health, memory, stress response, and cancer defense. For decades, researchers suspected a transporter had to exist, but it . ...

A colossal ocean current encircling Antarctica--stronger than all the world's rivers combined--played a far more complex role in shaping Earth's climate than scientists once thought. New research shows it didn't form just because ocean gateways ...

A remarkable fossil discovery in southwest China is rewriting the story of how complex animal life began, showing that many key animal groups appeared millions of years earlier than scientists once believed. Dating back over 540 million years, the .. ...

Earth may have won a cosmic chemistry lottery. Researchers found that during the planet's earliest formation, oxygen had to be in an extremely narrow "Goldilocks zone" for two life-essential elements, phosphorus and nitrogen, to stay where life could ...

A strange "forbidden" planet spotted by the James Webb Space Telescope is turning planetary science on its head. TOI-5205 b, a Jupiter-sized world orbiting a small, cool star, has an atmosphere surprisingly poor in heavy elements--even less enriched ...

Is consciousness something the brain produces, or is it woven into the fabric of reality itself? Renowned neuroscientist Christof Koch is challenging long-held scientific assumptions by confronting the "hard problem" of consciousness -- why and how . ...
