Optomechanics Motions of the quantum collectiveIan S. OsborneMicro- and nanomechanical oscillators can now be manipulated in the quantum regime. They can be entangled with other degrees of freedom and used for quantum teleportation and quantum storage. To date, these systems have been limited to single or pairs of oscillators. Chegnizadeh et al. now demonstrate scale-up, preparing a collective macroscopic system composed of several individual mechanical oscillators in the quantum ground state.

Virology Cold diversity hotspotsCaroline AshAntarctic giant viruses such as those found in the waters off Greenwich Island are now at risk due to climate change. PHOTO: TRAVEL FOTOWORLD/GETTYIMAGESGiant viruses are important components of marine food webs. Their hosts span a range of eukaryotic organisms, and they associate with the collapse of algal blooms. Using genome-resolved metagenomics, Buscaglia et al.

As seedlings begin to navigate through soil after germination, an apical hook is formed by bending of the upper hypocotyl that protects the fragile shoot meristem.

Plant Science Volatile communicationAnkit WaliaDevelopment of the pistil, visible here as the central green structure, is guided in part by volatile organic compounds in petunias. Open in viewerPlant responses to chemical signals carried through the air are critical for development, fitness, and adaptation. Stirling et al. identified a mechanism for the perception of the volatile compound (–)-germacrene D through a homolog of the Karrikin receptor KAI2 in petunia pistils.
