An international team of researchers from Austria and the UK has shown that Goffin’s cockatoos (Cacatua goffiniana) can manufacture and use stick-type tools of appropriate shape and length out of three different materials, suggesting that the birds can anticipate how the tools will be used. Goffin’s cockatoos can cut out elongated tools of a cardboard to rake pieces of food. Image credit: Bene Croy. Tool manufacture was once regarded as a defining...

Piezo proteins transduce physical forces and are activated by mechanical indentation and stretching of cell membranes. By reconstituting these channels in lipid bilayers, Syeda et al show that Piezo 1 channels are stimulated in the absence of other cellular components via a variety of methods, including osmotic imbalance and membrane perturbation.
