“Researchers have conducted a genetic analysis of more than 6,000 Atlantic cod from different regions of the ocean, using DNA markers. They found that the cod clustered into five distinct groups, based on their geographic origin and migration patterns. These groups showed little or no evidence of interbreeding, suggesting they are reproductively isolated and may represent different species. This finding has implications for the conservation and management of Atlantic cod, as each group may have different ecological and evolutionary traits.“
“Researchers have found that superb fairy-wrens can learn to associate unfamiliar sounds with danger through social learning. The birds were played a computer-generated “buzz” as part of a chorus of alarm calls from other bird species. By the end of the training period, 80% of the birds flew away and hid if they heard the computer buzz on its own. The study is the first to show the specific mechanism of social learning through acoustic-acoustic association.“
“Scientists have identified a vector of horizontal gene transfer (HGT) in worms, which could lead to the discovery of further vectors of HGT in eukaryotes. HGT is a major evolutionary force within microbial communities and allows for the acquisition of novel traits that are unique…”
Meet the polyester bees, the single moms of the insect world who make their own plastic and brew their own beer for their kids. These bees belong to the Colletidae family and have a unique way of taking care of their young. They use a gland on their abdomen to secrete lactone molecules…, Continue reading “Polyester Bees Brew Beer-Scented Baby Food in Plastic Cribs”
The article tells the story of Cassius, a saltwater crocodile who is the world’s largest captive croc and who just turned 120 years old. Cassius was captured in 1984 on a cattle farm in Australia, where he was causing trouble by eating livestock. He was then moved to a crocodile park on Green Island, where he has been living ever since. Continue reading “World’s Largest Captive Croc Turns 120 Providing Real Insights into Longevity”
The article describes a new discovery of ancient steroids in rocks that are 1.6 billion years old. These steroids are produced by eukaryotic organisms, which are cells with nuclei and membrane-bound organelles. Eukaryotes include plants, animals and fungi, and they are more complex than prokaryotes, which are cells without nuclei and organelles.
