Bow-tie particles boast a tunable twist p.395

Particles that self-assemble from nanoribbons into bow-tie-shaped structures can be tailored to change the degree of their twist. A search for how best to quantify this twist homes in on a measure of how the bow ties respond to light.

Bacterial meningitis hits an immunosuppressive nerve p.396

Bacteria that cause meningitis have been found to stimulate nerve fibres in the brain’s meninges to release a neuropeptide molecule that dampens the response of immune cells and aids bacterial invasion of the central nervous system.

Bleb protrusions help cancer cells to cheat death p.402

Processes that regulate cell death can rid the body of cancer cells. However, some of these cells have ways to thwart such processes, and one such death-defying mechanism has been found to rely on cellular protrusions called blebs.
