Nature's web forum on access to the primary literature has highlighted the risks, as well as the attractions, in enforcing availability without charge to readers.
Every summer, Florida plays host to researchers who fire rockets at the sky to create lightning. And having captured the bolts, the group has found something shocking, as Mark Schrope finds out.
They were hailed as wonder drugs to banish depression, but may cause suicidal thoughts in some children. Companies are under attack for failing to publish these data. Erika Check considers the science behind a scandal.
Analyses of a new ice core from Greenland yield the first high-resolution picture of the start of the last ice age in the Northern Hemisphere, and of the onset of climate instability as our planet cooled.
Biologists use phylogenetic trees to depict the history of life. But according to a new and roundabout view, such trees are not the best way to summarize life's deepest evolutionary relationships.
In computationally active areas of the brain, the blood flow is increased to provide more energy to nerve cells. New data fuel the controversy over how this energy supply is regulated.
Coherent coupling of superconducting qubits and electromagnetic modes, analogous to atom–photon coupling, has been demonstrated — a step towards the communication of quantum information.
A common trend in size differences between males and females is a long-standing puzzle. A study of shorebirds shows that the type and strength of competition for mates may explain much of the pattern.
Cells communicate through signals that must be propagated from cell surface to nucleus. Tracking the signals generated by the transforming growth factor-β protein reveals a surprising partner in this process.
