The perception of timbre

Timbre is an auditory attribute that conveys important information about the identity of a sound source, especially for music. Thoret et al. re-analyse past research to identify the multiple acoustical facets of musical instrument perception, capitalizing on spectrotemporal modulation models and metric learning.

    Donald Trump’s presidency oversaw the relentless dismantling of many of Barack Obama’s policy legacies. For the climate-conscious, perhaps the most painful were Trump’s reneging on the United States’ commitment to the Paris Agreement, the dramatic changes at the US Environmental Protection Agency (EPA) and the rollback of a number of greenhouse gas reduction policies. The new Biden administration will soon have an opportunity to undo these reversals and put America back on the climate map.

As the pandemic experience has shown, online meetings are a viable alternative. Accelerating efforts to improve conferences in virtual formats can lead to a more equitable and sustainable conference culture.

    Obtaining accurate dates for rock art is important to both archaeologists and Aboriginal Traditional Owners, but a lack of organic material associated with rock art can make this challenging. Using radiocarbon dating of mud wasp nests, Finch et al. show that naturalistic depictions of animals in the Kimberley region of northern Australia date to between 13,000 and 17,000 years ago.

    To date, studies of gambling harms have been limited by reliance on small samples and self-reports of behaviour. Analysis of banking transactions provides unique insights into the scope and sequencing of gambling harms at the individual and population levels, with implications for gambling policy, regulation, and harm minimization.
