The sound of rain spurs rice seeds to sprout up to 40 percent faster than they would otherwise, according to a study published today in Scientific Reports.

To fuel our bodies, we must eat other living things, killing them in the process. However, most plants and algae are autotrophs. They bootstrap their biomass without the barbarism of eating others: using photosynthesis, turning sunlight, water, and carbon into energy.

Crushed clean, dry eggshells, when scattered over the soil, are intended to stop adult gnats from laying eggs and potentially add natural fertilizer. However, they merely sit on the surface, collecting dust, while the gnats remain attracted to the damp compost.

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.

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.

A maggot's age and species can give essential information to forensic entomologists investigating murders. Combing through these fly larvae, investigators can potentially learn when and where a crime happened, whether the body has been moved or whether toxins were involved. For example, blowflies are among the earliest insect colonizers of corpses; they typically sniff out and lay eggs on a dead body within minutes to hours.

First came the heavy winter rains that soaked the soil. Then, the sunny weather not too hot, but just warm enough to fuel the growth. A few more winter rainfalls and Southern California could be ripe for an epic wildflower season in the coming weeks and months. And when they bloom the vibrant colors popping from rolling hills as far as the eye can see thousands of people are bound to seek out their beauty, if past years are any indication.

"Granted, "[p]lants have extensive and well established mechanisms of communication, with that of volatiles being the most well studied and understood," he added. "There is also growing recognition that root exudates play a role in plant-plant interactions, though this is only now being deeply investigated. Nothing else, communication through mychorriza, has withstood independent investigation."

It was previously thought that tropical regions where temperatures fluctuate less over the course of the year would not be so affected by the climate crisis in terms of the timing of flowering. This hypothesis has been proved wrong, said the lead researcher Skylar Graves from the University of Colorado Boulder, who added that nowhere on Earth is unaffected by climate change.

On a spring day in 1694, Antonie van Leeuwenhoek - the father of microbiology - used a magnifying lens to look at a candle through the dissected eye of a dragonfly. But instead of seeing 1 candle flame, he saw hundreds of tiny flames, repeated over and over. But spoiler alert - this is not how insects see. Hi, I'm Niba, and today we're going to explore how insects really see the world.

Although there are many amber stones containing a single creature, there are fewer that include two or more, as is the case with a pair of mosquitoes trapped in amber 130 million years ago which tell us that, back then, males also sucked blood. Even more extraordinary is when several organisms can be seen interacting, either eating the other, acting as a parasite, or cooperating.

When Borkent stops working, biting midges risk becoming an orphan group, a term that taxonomists give for a branch of the web of life that is no longer being studied. It is a pattern playing out across the field, he says. I am one of the last few standing. It's crisis all around. As the taxonomic community ages, we are not being replaced.
