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.

Individuals allergic to bee stings can safely consume honey because the venom produced by bees is not related to honey. The venom is injected through the stinger, while honey is produced from nectar.

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.

Around a third of UK gardeners use pesticides, and our studies found that house sparrow numbers, for example, were nearly 40% lower in gardens where the pesticide metaldehyde was used. By reducing pesticide use, you can actively encourage birds back into your outdoor spaces, as they rely on invertebrates such as slugs and snails as natural prey.

This study started from a discussion with my co-author and postdoctoral researcher, Sabrina Rondeau, whose recent findings showed that these queens can survive submersion for over a week, which is extraordinary for a terrestrial insect. We wanted to understand how that's even possible.

For its fifth anniversary, 'Secrets of' turns its lens to one of Earth's smallest yet most vital heroes: bees. Far more than pollinators, bees are socially complex, fast-thinking individuals and the most important insects on our planet. Their impact on the natural world and humanity is immeasurable, and we're only just beginning to see how extraordinary they truly are.

A small, stingless bee may be able to raise coffee yields while fitting into real-world pest control programs, according to a new study from Brazil. In a field study on full-sun arabica farms, researchers reported a 67% higher fruit yield on coffee branches closer to colonies of the native stingless bee Scaptotrigona depilis, compared with branches farther away. The study was recently published in Frontiers in Bee Science.

When you think of farming, what ingredients do you generally associate with a successful harvest? The basics certainly come to mind: fertile soil, plenty of sunlight and lots of water. But there are other variables that can also mean the difference between a crop of healthy fruits and vegetables and a large heap of organic waste. And it turns out that one of those variables is a very small hawk.
