Researchers have demonstrated a new optical atomic clock that uses a single laser and doesn’t require cryogenic temperatures. By greatly reducing the size and complexity of atomic clocks without sacrificing accuracy and stability, this advance could lead to high-performance atomic clocks that are compact and portable.
A beautiful butterfly is able to fool ants into rearing its young by masking them with the ants’ own smell, say researchers.
Caterpillars of the alcon blue butterfly have developed an outer coat that tricks ants into believing the young are its own, duping the ants into carrying the larvae back to their colonies to care for.
But what is more, the ant seems to “recognise” that it is being duped and one population appears to be engaging in an evolutionary arms race with the butterfly, says the team led by David Nash at the University of Copenhagen, Denmark.

Transistors, the building blocks of integrated circuits, face growing challenges as their size decreases. Developing transistors that use novel operating principles has become crucial to enhancing circuit performance.
Hot carrier transistors, which utilize the excess kinetic energy of carriers, have the potential to improve the speed and functionality of transistors. However, their performance has been limited by how hot carriers have traditionally been generated.
A team of researchers led by Prof. Liu Chi, Prof. Sun Dongming, and Prof. CHeng Huiming from the Institute of Metal Research (IMR) of the Chinese Academy of Sciences has proposed a novel hot carrier generation mechanism called stimulated emission of heated carriers (SEHC).
In this Review, Panzeri, Moroni, Safaai and Harvey explain how the levels and structures of correlations among the activity of neurons in a population shape information encoding, transmission and readout, and describe how future research could determine how the structures of correlations are optimized.
