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 at Oregon State University have captured something researchers have long struggled to see: the real-time chemical interactions that help drive Alzheimer's disease. By watching how metal ions--especially copper--trigger harmful protein ...

A gene called KLF5 may be a key force behind the spread of pancreatic cancer--but not in the way scientists expected. Rather than mutating DNA, it rewires how genes are turned on and off, helping tumors grow and invade new areas. Researchers found it ...

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 single week of intensive meditation and mind-body practices led to measurable changes across the brain and body. Researchers observed improved brain efficiency, boosted immune signaling, and increased natural pain relief chemicals in participants' ...

A surprising new study reveals that what you eat could play a powerful role in fighting cholera, a deadly diarrheal disease. Researchers found that diets rich in certain proteins--especially casein from dairy and wheat gluten--can dramatically reduce ...

A team of engineers has created a breakthrough memory device that keeps working at temperatures hotter than molten lava, shattering one of electronics' biggest limits. Built from an unusual stack of ultra-durable materials, the tiny component can ...

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 ...
