Chromosome Y Y Chromosome Species Dna Study
- The Y chromosome in primates — including humans — is evolving much more rapidly than the X chromosome, new research on six primate species suggests. For instance, humans and chimpanzees share upwards of 98% of their DNA across the whole of the genome, but just 14% to 27% of the DNA sequences on the human Y chromosome are shared with our closest living relatives.  The finding surprised scientists, given that humans and chimpanzees diverged just 7 million years ago — a blip ...

Monotremes Professor Patricia Vickers Years Species Platypus
- Australian researchers have discovered the oldest confirmed platypus specimen along with a new species they've named 'echidnapus.' This newly identified species combines characteristics of platypuses with traits that are more typical of echidnas. In a study recently published in Alcheringa: An Australasian Journal of Palaeontology , a team of Australian scientists from the Australian Museum, Museums Victoria, and the Australian Opal Centre have unveiled evidence suggesting an 'Age of ...

E Woodii Cycads South Africa Plant Ngoye Forest Cones
- The plant has been propagated worldwide, but every surviving specimen of Encephalartos woodii is a male clone – and without a female, natural reproduction is impossible. "Surely this is the most solitary organism in the world," wrote palaeontologist Richard Fortey in his book about the evolution of life. He was talking about Encephalartos woodii ( E. woodii ), a plant from South Africa. E. woodii is a member of the cycad family, heavy plants with thick trunks and large stiff leaves that ...

Birds Species Birdlife International List Bird Years
- The birds have not been seen for at least a decade – some for more than 100 years – but the authors of a new list of missing species have not given up hope The coppery thorntail and New Caledonian lorikeet are among the 126 birds "lost" to science, having not been seen for a decade or more, according to the most comprehensive list of missing species composed to date. The new tally is based on millions of records collected by enthusiastic birders and amateur scientists documenting ... [Read More]


New Zealand Southern Hemisphere Years Dinosaurs New Zealand's South Island Sea
- An international team of scientists has identified the oldest fossil of a sea-going reptile from the Southern Hemisphere -- a nothosaur vertebra found on New Zealand's South Island. 246 million years ago, at the beginning of the Age of Dinosaurs, New Zealand was located on the southern polar coast of a vast super-ocean called Panthalassa. 'The nothosaur found in New Zealand is over 40 million years older than the previously oldest known sauropterygian fossils from the Southern Hemisphere. An ... [Read More]


Toads Cane Areas Study Macquarie University Cane Toads
- After South American cane toads were introduced to Australia in the 1930s to control pestilent beetles, they ravaged the country's ecosystems—and their disruption continues today . These invasive amphibians secrete toxins from their skin, killing pets and other predators that eat them. The yellow-spotted monitor, a big lizard found mainly in Australia, has been especially hard-hit: populations have declined by more than 90 percent in most areas where cane toads invaded, with cascading ...

Mosquitoes Riffell Video West Nile Mosquito Humans
- A s the weather starts heating up this week, you may be tempted to go outside—but with the outdoors comes the possibility of getting bitten by mosquitoes. And if you find yourself getting a lot of mosquito bites, it could be because of the way you smell or the colors of the clothes you are wearing, recent research has found. "If you think you are a mosquito magnet, it's probably the case," Jeffrey Riffell, a biology professor at the University of Washington who studies mosquito sensory ... [Read More]

Learning Titipounamu Birds Vocal Learning Study New Zealand's
- In the world of birdsong , some species stand out for their vocal learning ability to learn new sounds, such as parrots, songbirds, and hummingbirds. Recently, researchers have uncovered that New Zealand's smallest bird, the titipounamu, may also possess a rudimentary version of this talent. Rethinking vocal learning in birds Research from the University of Auckland is challenging traditional views on how and when vocal learning evolved in birds. Until now, scientists believed that birds were ... [Read More]

Carbon Forests Forest Emissions Trees Climate
- Australia contains some of the world's most biologically diverse and carbon-dense native forests. Eucalypts in wet temperate forests are the tallest flowering plants in the world and home to an array of unique tree-dwelling marsupials, rare birds, insects, mosses, fungi and lichen, many of which have not even been catalogued by scientists. Yet our country remains in the top ten list globally for tree cover loss, with almost half of the original forested areas in eastern Australia cleared. This ... [Read More]

Joro Spiders Joro Spiders East Coast Humans Species
- Adults are most commonly seen in August and September. A large, brightly colored invasive species called the Joro spider is on the move in the United States. Populations have been growing in parts of the South and East Coast for years, and many researchers think it's only a matter of time before they spread to much of the continental U.S. But spider experts say we shouldn't be too worried about them. "My sense is people like the weird and fantastic and potentially dangerous," said David Nelsen, ... [Read More]

Snow Snow Leopards Leopards Plants Study Plant
- Snow leopards, those majestic creatures of the snow-capped peaks, are renowned for their stealthy hunting skills and carnivorous diet. But what if these apex predators have a secret – a surprising preference for plants? A fascinating study from Kyoto University has uncovered this unexpected behavior, showing that these elusive cats are not strictly meat-eaters. By analyzing the DNA present in their feces, researchers have found that snow leopards consume a significant amount of plants, ... [Read More]

Edna Biodiversity Freshwater River Fish Ecosystems
- Freshwater ecosystems are the lifeblood of the natural world, yet they are facing a silent crisis. A 2022 report by the World Wildlife Fund revealed a staggering 83% decline in global freshwater vertebrate populations since 1970, a rate far exceeding that of any other habitat. The level of degradation to nature is alarming, but ecosystems are complicated, as are the effects of human activity. So, the story is often more nuanced. Our research shows how analyzing environmental DNA ... [Read More]
