As the resources required by artificial intelligence increase unsustainably, an analog design provides an energy-efficient alternative to digital computer chips — and one that is ideally suited to neural-network computations.

Two brain–computer interfaces have been developed that bring unprecedented capabilities for translating brain signals into sentences — at speeds close to that of normal speech, and with vocabularies exceeding 1,000 words.

Biologists have long sought to understand the factors that enable coral reefs to thrive. A careful analysis of nutrient cycling now points to an unexpected food source that helps to sustain corals during food scarcity.

This Review provides a perspective on the development of non-cancer therapies based on human genetics studies and suggests measures that can be taken to streamline the pipeline from initial genetic discovery to approved therapy.
