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.

During major floods, thousands of tiny fish convene at Luvilombo Falls in the upper Congo River Basin to undertake a peculiar vertical migration, described for the first time today in Scientific Reports.

Red-necked keelback snakes possess a potent toxin derived from the toads they consume, which can cause severe harm to predators like mongooses. The snakes store these toxins in specialized nuchal glands.

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.

Young fish that spent more of their waking hours being active tended to live longer than did more-sluggish fish. Young fish that restricted their sleep schedule to evening hours also reached a riper age than did those that slept more during the day.

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 comprehensive analysis of Google search patterns related to birds explores what species people seek information about most frequently. The investigation spans six interconnected analyses examining bird variety, taxonomic classifications, information sharing behaviors, birder sighting correlations with search trends, regional popularity differences across states, and temporal patterns in search interest.

Few transformations in the history of life have been as extreme as the embrace of the ocean by seagrass. Like whales and dolphins, modern seagrasses descend from land-dwelling ancestors.

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.

The bodies of the crabs displayed male reproductive structures, while other parts showcased female features, including gonopores, said K.S. Anoop Das.

London is the only place in the UK where you can find scorpions, snakes, turtles, seals, peacocks, falcons all in one city and not London zoo. Step outside and you will encounter a patchwork of writhing, buzzing, bubbling urban microclimates. Sam Davenport, the director of nature recovery at the London Wildlife Trust, emphasises the sheer variation in habitats that you find in UK cities, which creates an amazing mosaic of wildlife.

These caterpillars use a surprisingly complex rhythm like a secret knock to convince the ants to come fetch them. That's according to research published on February 25 in Annals of the New York Academy of Sciences, which found that caterpillars can keep a beat called double meter that has so far been identified only in a couple of primates.

What's scarier than a spider? A really big spider, of course. A newfound defensive tactic takes advantage of this idea: researchers documented spiders building giant spiderlike silhouettes on their webs to ward off predators. These decoys are an example of web decorations that some spiders are known to produce, often to prevent getting eaten, avoid bird strikes or attract prey.

Signs of ageing accelerated when fish were exposed to the chemicals, according to the study, which could have implications for other organisms. Chemical safety regulations tend to focus on short-term exposure to high doses of pesticides and other chemicals, but the study focused on long-term exposure. Low doses of pesticides are widespread in the environment, so their effects should be studied and understood, the authors said.

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.

Some deep-sea fish may be able to see light in a different way from most other vertebrates, according to a new study. The fish, found in the Red Sea, have what the scientists behind the new study describe as hybrid photoreceptorslight-sensing cells in the retina that combine elements of two distinct kinds of photoreceptors, cones and rods. In human retinas, cone cells enable us to see in bright environments, detecting color and fine detail,
