A female typically mates with five males simultaneously, although groups of 10 to 15 are not unusual Female African treefrogs mate with several males at the same time, working together to whip up a larger foam nest that protects hundreds of eggs from drying out.This group nest-building behaviour provides a fresh explanation for why females…
Credit: Erik Karits from Pexels Hummingbird hawkmoths may have their own version of being left-handed or right-handed, using one preferred eye and one side of their long feeding tube together to search flowers for nectar.The discovery, made by a team of biologists at the University of Konstanz, shows how creatures with small brains save mental…
King ratsnake is known for hunting and eating deadly venomous snakes (Inaturalist photos) A nonvenomous snake that regularly hunts and eats some of the world’s most dangerous venomous snakes has given scientists a new mystery to solve. Researchers have now mapped the genome of the king ratsnake to understand how it survives the venom of…
When surprised, a myotonic goat’s muscles briefly stiffen, sometimes making it fall over. A viral video that has received more than 5.4 million likes shows a baby goat jumping down from a small staircase before suddenly freezing with all four legs stiff and toppling over. Within seconds, it gets back on its feet and starts…
Astronomers have directly detected four previously hidden white dwarfs orbiting nearby red dwarf stars, solving a long-standing observational challenge and improving our understanding of how close binary star systems evolve. The newly confirmed stellar remnants lie within 20 parsecs (around 65 light-years) of the Sun and had remained concealed because their faint light was overwhelmed…
Unwritten social rules, not government oversight, help keep forest land sustainable Slash-and-burn farming was blamed for destroying rainforests, but a study of 18,000 forest patches found community rules can limit clearing and allow trees to return.Published in the Proceedings of the National Academy of Sciences, the research shows that unwritten social rules in small communities…
Mangroves-A forest that would not vanish across the globe Mangroves have long been considered one of the planet’s most threatened ecosystems. These dense forests along tropical and subtropical coastlines were steadily being lost to urban expansion, shrimp farming, agriculture, pollution and climate change. Each year thousands of hectares were lost, threatening wildlife, fisheries and coastal…
China achieves 99% hybrid rice seed cloning with HUAXU gene, cuts annual seed costs China’s new hybrid rice can preserve its high-yield traits across generations, potentially allowing farmers to replant seeds instead of buying new ones every year.Scientists at the China National Rice Research Institute in Hangzhou have developed a self-cloning hybrid rice system that…
Maya Biosphere Reserve covers about 2.1 million hectares in Guatemala’s northern PetEn province Logging is one of the biggest reasons forests are disappearing. When trees are cut faster than they can grow back, wildlife loses its habitat, and local communities are impacted. But in northern Guatemala, one protected forest is showing that logging does not…
