Eighteenth century nautical charts reveal coral loss

A new study using old nautical charts and satellite data found that more than half of the coral reef habitat mapped in the 1770s was no longer there, with some areas experiencing up to 90% loss. The research has important conservation implications and highlights the need for a shifted spatial baseline.

Scratch-and-sniff test could predict Parkinson's even earlier

A study published in Neurology found that a scratch-and-sniff test may predict Parkinson's disease up to six years before diagnosis. The test showed strong links between smell and disease risk for white participants, but weaker associations for black participants. Older men with poor sense of smell were more likely to develop the disease.
