Science news — discovery, health and the environment

The Science section brings together the latest in research and discovery: space and astronomy, health and medicine, the climate and environment, biology, physics and the natural world. We follow the studies and the breakthroughs and explain what they mean in plain language.

We separate solid evidence from early findings, attribute the research, and give you the context to understand why a discovery matters — for the planet, for public health and for everyday life.
