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.
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.
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.
Frogmouths have another life that few people see: like vampires, they wake at sunset and night-hunt until dawn. These stolid creatures turn into zephyrs that silently swoop, catching prey on the ground and in the air.
We think that in this early deuterostome, the median eye contained both ciliary and rhabdomeric cells. As a result, both cellular lineages were incorporated into a single, ancient, cyclopean eye, which later evolved into the vertebrate eyes.
Because we're homeotherms, we assume all mammals work the way we do. But in recent years, as improvements in technology allowed researchers to more easily track small animals and their metabolisms in the wild, we're starting to find a lot more weirdness.
Recently, two unexpected examples by a wild wolf and a domesticated cow named Veronika attracted global attention and once again opened the door for experts and others to weigh in on the question, "Are these really examples of tooling?" Many people are eager to know more about the nitty-gritty details of tooling, so I am thrilled that Dr. Benjamin Beck, an expert in this area, could answer a few questions about this fascinating behavior.
Wooden objects carrying the marks of carving and use could be the oldest wooden tools ever found. Researchers dated the artefacts, found in what is now Greece, to 430,000 years ago - and suggest they might have been made by early Neanderthals or their ancestors, Homo heidelbergensis. A separate study describes 480,000-old flint-knapping tools made from antler and elephant bone, from what is now the United Kingdom.
An elephant's trunk is a marvelous thing, flexible enough to bend and stretch as it forages for food, but also stiff enough to grasp and maneuver even delicate objects like peanuts or a tortilla chip. That's because the trunk is highly sensitive when it comes to sensing touch. Scientists have determined that the whiskers lining the trunk are crucial for that sensitivity thanks to their unique structure, amounting to a kind of innate "material intelligence, according to a new paper published in the journal Science.
I'm always looking for books that challenge the status quo, and when I learned about Roland Ennos' new book The Powerful Primate: How Controlling Energy Enabled Us to Build Civilization, I couldn't wait to get my eyes on it, and I'm thrilled I did. In this landmark book, Ennos offers "a compelling argument that flips the traditional view of humanity on its head."
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.
