Hayabusa

Japan's Hayabusa spacecraft brought back the solution to the mystery of the source of Earth's most common meteorites.

Ancient Interbreeding

Most living people carry bits of archaic DNA, suggesting that our ancestors mated with other archaic peoples.

Photosystem II

This year, researchers in Japan mapped the structure of photosystem II, a protein essential for photosynthesis.

Pristine Gas

Scientists saw pristine clouds of hydrogen this year that may be surprisingly long-lasting leftovers from the big bang.

Microbiome

Researchers found that far from being random, our internal microbial communities fall roughly into three enterotypes.

Malaria Vaccine

After decades of disappointments, the results seen in smaller trials of a malaria vaccine called RTS,S have held up.

Exoplanets

Scientists have discovered planetary systems that are forcing them to rethink how planets form and settle into orbits.

Designer Zeolites

This year, researchers found new ways to tailor the size of zeolite pores and create thinner, cheaper membranes.

Senescent Cells

Solid evidence shows that cells that no longer divide promote aging and that culling them could keep us healthier longer.
