A fossil unearthed in Great Britain may end a long-running debate about the mollusks, one of life’s most diverse invertebrate groups: Which evolved first, shelled forms like clams and snails, or their shell-less, worm-like relatives? (more…)
A new species of plant-eating dinosaur with tiny, 1-inch-long jaws has come to light in South African rocks dating to the early dinosaur era, some 200 million years ago.
This “punk-sized” herbivore is one of a menagerie of bizarre, tiny, fanged plant-eaters called heterodontosaurs, or “different toothed reptiles,” which were among the first dinosaurs to spread across the planet. (more…)
GAINESVILLE, Fla. — By analyzing the genes of bacteria, University of Florida researchers have moved a step closer to pinpointing how two brain disorders common in small-breed dogs occur.
The researchers found that the bacteria, known as Mycoplasma canis, invade dog’s cells and suppress their immune system responses. (more…)
Fishing hooks aren’t the only hooks found in east-central Mexican waters.
A new species of freshwater fish described by a North Carolina State University researcher has several interesting – and perhaps cringe-inducing – characteristics, including a series of four hooks on the male genitalia. (more…)
COLUMBUS, Ohio – Coyotes living in cities don’t ever stray from their mates, and stay with each other till death do them part, according to a new study. (more…)
University of Exeter scientist Dr Fiona Mathews has discovered one of Britain’s rarest mammals living in East Devon.
Members of the public were treated to a surprise close-encounter with the Grey long-eared bat, believed to be one of only 1,000 individuals in the country, at an event organised by East Devon District Council’s Countryside Service at the Axe Estuary Wetlands.
The bat evening was part of a regular Wet and Wild Weekend – a celebration of the wildlife of the Axe Estuary Wetlands attracting nearly 500 people. Dr Mathews and fellow bat-enthusiast Adrian Bayley had set up mist nets so that people could meet some of the animals they were hearing on bat detectors, and were amazed to find the country’s rarest bat.
There are only six known breeding colonies of Grey long-eared bats in the UK. This discovery potentially links an isolated group near Newton Abbot with colonies in Dorset and the Isle of Wight. (more…)
If two birds meet deep in the forest, does anybody hear? Until now, nobody did, unless an intrepid biologist was hiding underneath a bush and watching their behavior, or the birds happened to meet near a research monitoring station. But an electronic tag designed at the University of Washington can for the first time see when birds meet in the wild.
A new study led by a biologist at Scotland’s University of St. Andrews used the UW tags to see whether crows might learn to use tools from one another. The findings, published last week in Current Biology, supported the theory by showing an unexpected amount of social mobility, with the crows often spending time near birds outside their immediate family.

International team of scientists finds adaptations to stress in oyster genome
When it comes to stress, oysters know how to deal. The tough-shelled mollusks can survive temperature fluctuations, toxic metals and exposure to air, and a new study of their genetic makeup is helping to explain how.
An international team of scientists, including the University of Delaware’s Patrick M. Gaffney, professor of marine biosciences, sequenced the genome of the Pacific oyster, Crassostrea gigas, in a Nature paper published on Sept. 19. (more…)
