An immune response with a sweet tooth p.37

A previously unknown pathway that enables mammalian cells to recognize infection and trigger an immune response requires a kinase enzyme in the host cell to bind a sugar molecule produced by infecting bacteria.

DNA tags used to image sugar-bearing proteins on cells p.38

Methods for imaging sugars attached to proteins — the protein glycoforms — are of interest because glycoforms affect protein movement and localization in cells. A versatile approach is now reported that uses DNA as molecular identity tags.

Spotlight on proteins that aid malaria p.41

The multiprotein complex PTEX enables malaria-causing parasites to survive inside red blood cells. Studies reveal how PTEX assembles, and identify a function for one of the complex’s proteins, EXP2.

Designer atom arrays for quantum computing p.43

A key step in the development of quantum computers that use neutral atoms as quantum bits is the assembly of tailored 3D arrays of atoms. Two laser-based approaches have now been reported to do this.

Facing up to the global challenges of ageing p.45

Longer human lives have led to a global burden of late-life disease, and so interventions, including changes to lifestyle and medical innovations, are needed to prevent disease and increase late-life health.

All-inorganic perovskite nanocrystal scintillators p.88

All-inorganic perovskite nanocrystals containing caesium and lead provide low-cost, flexible and solution-processable scintillators that are highly sensitive to X-ray irradiation and emit radioluminescence that is colour-tunable across the visible spectrum.

Sulfoxaflor exposure reduces bumblebee reproductive success p.109

Chronic exposure to sulfoxaflor (a sulfoximine-based insecticide) has severe sub-lethal effects on bumblebee (Bombus terrestris) colonies; exposed colonies produced fewer workers and fewer reproductive offspring than unexposed control colonies.
