The U.S. government is divesting from mRNA vaccines, but will other uses of the technology be spared? In a time of uncertainty, scientists worry that revolutionary treatments for cancer, immune dysfunction and genetic disease may be left on the lab bench.

Blood tests that detect early cancer are coming to market. Could they lead to earlier diagnosis and treatment?

Emerging evidence suggests that plate tectonics, or the recycling of Earth's crust, may have begun much earlier than previously thought — and may be a big reason that our planet harbors life.

Astronomers are using radio pulses from space to find missing baryonic matter and learn about supermassive black holes, stellar formation and galaxy evolution.

Three years into its mission, the James Webb Space Telescope has advanced the search for alien life more than any machine before it. What will it find next?

Evidence is mounting that the evolution of our species is more convoluted than we imagined — more like a braided stream than a branching tree.

The technological singularity — the point at which artificial general intelligence surpasses human intelligence — is coming. But will it usher in humanity's salvation, or lead to its downfall?

Artifacts from the Iron Age have revealed an intense historical magnetic anomaly in the Middle East. Could using a similar approach elsewhere help us unravel the mysteries of Earth's magnetic field?

Invisible radiation leaking out of private satellites, like SpaceX's Starlink spacecraft, is disrupting radio astronomers' ability to detect important signals from across the universe. If left unchecked, we could reach an "inflection point" beyond which we can no longer properly study the cosmos, researchers warn.
