Nanoscale magnonic Fabry-Pérot resonator for low-loss spin-wave manipulation

Nature Communications, Published online: 16 April 2021; doi:10.1038/s41467-021-22520-6Compared to electromagnetic waves, the wavelength of spin waves is significantly shorter at gigahertz frequencies, enabling the miniaturisation of wave-based devices. Here, the authors present a magnonic Fabry-Pérot resonator allowing for nanoscale and reconfigurable...

Detecting protein and DNA/RNA structures in cryo-EM maps of intermediate resolution using deep learning

Nature Communications, Published online: 16 April 2021; doi:10.1038/s41467-021-22577-3It is challenging to extract structural information from EM density maps at intermediate or low resolutions. Here, the authors present Emap2sec+, a program for detecting nucleotides and protein secondary structures in EM density maps at 5 to 10 Å resolution.

DUSP16 promotes cancer chemoresistance through regulation of mitochondria-mediated cell death

Nature Communications, Published online: 16 April 2021; doi:10.1038/s41467-021-22638-7Chemoresistance is one of the main challenges for cancer therapy success. Here, the authors show that dual-specificity phosphatase 16 (DUSP16) expression is associated with chemoresistance in several types of cancer through impairing mitochondria-associated apoptosis.

Defective viral genomes as therapeutic interfering particles against flavivirus infection in mammalian and mosquito hosts

Nature Communications, Published online: 16 April 2021; doi:10.1038/s41467-021-22341-7Defective viral genomes (DVGs) can interfere with virus replication and provide a potential approach to control infection. Here, Rezelj et al. use a combined experimental evolution and computational approach to identify DVG sequences that optimally interfere with Zika...

A committed fourfold increase in ocean oxygen loss

Nature Communications, Published online: 16 April 2021; doi:10.1038/s41467-021-22584-4Ocean warming and changing circulation as a result of climate change are driving down oxygen levels and threatening ecosystems. Here the author shows that though immediate cessation of anthropogenic CO2 emissions would halt upper ocean oxygen loss, it would continue...
