A subset of dorsal clock neurons are identified in Drosophila as sleep-promoting cells, which participate in a feedback loop with pacemaker neurons to drive both midday siesta and night-time sleep.

Skin stem cells, but not their progenitors, are able to form tumours owing to the ability of oncogene-targeted stem cells to increase symmetric self-renewing division and a higher p53-dependent resistance to apoptosis.

Thin-film solar cells were fabricated using layered two-dimensional perovskites with near-single-crystalline out-of-plane alignment, which facilitates efficient charge transport leading to greatly improved power conversion efficiency with technologically relevant stability to light exposure, humidity and heat stress.

Iron-containing zeolites have an exceptional ability to convert methane into methanol, but their active site have been hard to study; now, magnetic circular dichroism has been used to explore the reactive species, providing a technique that should be generally applicable, and revealing the value of constraining active sites within a lattice to improve catalyst functionality.

The long-sought direct formation of a bond between two sp3-hybridized carbon atoms is achieved by the merger of photoredox and nickel catalysis using only simple carboxylic acids and alkyl halides as starting materials.

Experiments show that magnesium oxide can dissolve in core-forming metallic melts at very high temperatures; core formation models suggest that a giant impact during Earth’s accretion could have contributed large amounts of magnesium to the early core, the subsequent exsolution of which would have generated enough gravitational energy to power an early geodynamo and produce an ancient magnetic field.

Natural variation in the courtship song of Drosophila is mapped to the intronic insertion of a retroelement at the slowpoke locus, which encodes an ion channel.

Sleep-promoting neurons in Drosophila are shown to switch between electrical activity and silence as a function of sleep need; the switch is operated by dopamine and involves the antagonistic regulation of two potassium channels.
