Organismal biology and ecology have primarily been defined by what scientists could observe from the outside. Researchers mapped migration routes, measured metabolic rates, and sequenced genomes with clinical precision. Yet, the field remained locked out of the internal lives of its subjects. Animal...

Why the personalized mRNA cancer vaccine suddenly matters The phrase personalized mRNA cancer vaccine sounds like sci fi. Like nuclear fusion, it seems like a promise that will always live a few years away from reality. For decades, cancer vaccines have cycled through hope and disappointment. While...

Scientists are inching closer to creating lab made human eggs—and even sperm—from ordinary cells. A recent study marks real progress, building on animal work that already produced mice from lab-made gametes. The promise is immense, but precision and ethics will shape when this technology reaches the...

Trump’s research funding cuts threaten health, climate, and innovation. Learn what’s at risk—and how you can help fight back to save American science.

What turns brain activity into conscious experience? Learn how researchers are using neuroscience to identify when and where awareness lights up in the brain.

Introduction Climate change, deforestation, and species extinctions often seem like vast, distant forces. But our food choices, particularly when they include animals, directly drive these global challenges. The environmental impact of meat touches nearly every part of the planet, from the climate to...
