The work these technicians are doing is as meticulous as that of engineers layering silicon on a microchip. Their job is to produce trial batches of perfumers' scent formulas, typically as many as 250 a day, which will be evaluated, tweaked and made again until one version is finalized.
A study by researchers at the University of California Berkeley has found that ethanol is surprisingly common in floral nectar, the sugary fuel that keeps pollinators alive. Yeast feeding on those sugars produces trace amounts of alcohol, and in this study, it showed up in 26 of the 29 plant species sampled.
The fireflies were most likely to change their own flashing rhythm in response when the LED blinked almost, but not quite, at the same time as the fireflies. The males would speed up their next flash if the LED blinked just before and waited a bit longer for their next flash when the LED blinked right after.

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.

Male skunks spray each other when they fight over females, and females spray males they don't want as mates.
