Published Ancient large kangaroo moved mainly on four legs, according to new research



A type of extinct kangaroo that lived during the Pleistocene around two and a half million to ten thousand years ago, known as the 'giant wallaby', was a poor hopper, a study has found.
Published Life underground suited newly discovered dinosaur fine



A newly discovered ancestor of Thescelosaurus shows evidence that these animals spent at least part of their time in underground burrows. The new species contributes to a fuller understanding of life during the mid-Cretaceous -- both above and below ground.
Published Study projects major changes in North Atlantic and Arctic marine ecosystems due to climate change



New research predicts significant shifts in marine fish communities in the North Atlantic and Arctic Oceans as a result of climate warming.
Published Scientists discover how to improve vaccine responses to potentially deadly bacterium



Researchers have taken a leap forward in understanding how we might fight back against the potentially deadly MRSA bacterium. They have shown in an animal model that targeting a key suppressive immune molecule (IL-10) during the delivery of a vaccine improves the ability of the vaccine to protect against infection.
Published Ancient dingo DNA shows modern dingoes share little ancestry with modern dog breeds



A study of ancient dingo DNA revealed that the distribution of modern dingoes across Australia, including those on K'gari (formerly Fraser Island), pre-dates European colonization and interventions like the dingo-proof fence.
Published Restored oyster sanctuaries host more marine life



Oysters sanctuaries in Chesapeake Bay are working for more than just oysters. Compared to nearby harvest areas, sanctuaries contain more abundant populations of oysters and other animal life--and the presence of two common parasites isn't preventing that.
Published Brain size riddle solved as humans exceed evolution trend



The largest animals do not have proportionally bigger brains -- with humans bucking this trend -- a new study has revealed.
Published Migrating starlings are no copycats



Young, na ve starlings are looking for their wintering grounds independently of experienced conspecifics. Starlings are highly social birds throughout the year, but this does not mean that they copy the migration route from each other. By revisiting a classic 'displacement' experiment and by adding new data, a team of researchers have settled a long-lasting debate.
Published Pasteurization inactivates highly infectious avian flu in milk, study suggests



Researchers found no infectious virus in the sampled pasteurized milk products tested for H5N1.
Published Blue and great tits deploy surprisingly powerful memories to find food



Blue and great tits recall what they have eaten in the past, where they found the food and when they found it, a new study shows. In the first experiment of its kind to involve wild animals, blue and great tits demonstrated 'episodic-like' memory to cope with changes in food availability when foraging. The same study may suggest that humans leaving out seeds and nuts for garden birds could be contributing to the evolution of these memory traits.
Published Giant salamander-like creature was a top predator in the ice age before the dinosaurs



Meet Gaiasia jennyae, the swamp creature with a toilet seat-shaped head. It lived 40 million years before the first dinosaurs, and it was the top predator in its ecosystem.
Published Extinct humans survived on the Tibetan plateau for 160,000 years



Bone remains found in a Tibetan cave 3,280 m above sea level indicate an ancient group of humans survived here for many millennia.
Published Ocean acidification turns fish off coral reefs



A new study of coral reefs in Papua New Guinea shows ocean acidification simplifies coral structure, making crucial habitat less appealing to certain fish species.
Published Genetic patterns of world's farmed, domesticated foxes revealed via historical deep-dive



Domesticated animals play a prominent role in our society, with two-thirds of American families enjoying the companionship of pets and many others relying on animal products for their nutritional needs. But the process of domestication remains a bit of a mystery.
Published Researchers identify unique survival strategies adopted by fish in the world's warmest waters



A team of researchers have identified unexpected ways coral reef fish living in the warmest waters on earth, in the Arabian Gulf, have adapted to survive extreme temperatures.
Published Sixty-million-year-old grape seeds reveal how the death of the dinosaurs may have paved the way for grapes to spread



Scientists discovered the oldest fossil grapes in the Western Hemisphere, which help show how after the death of the dinosaurs, grapes spread across the world.
Published New model could help provide expectant mothers a clearer path to safe fish consumption



Research creates a framework to better balance the nutritional benefit of fish consumption with the risk of mercury exposure to the developing brain.
Published Ammonites' fate sealed by meteor strike that wiped out dinosaurs



Ammonites were not in decline before their extinction, scientists have found.
Published New mathematical model sheds light on the absence of breastfeeding in male mammals



Mathematicians ave put forward a hypothesis which suggests that the reason male mammals don't breastfeed might be driven by the rich community of microbes that lives in breast milk and which plays an important part in establishing the gut microbiome of the infant.
Published Pacific cod can't rely on coastal safe havens for protection during marine heat waves



During recent periods of unusually warm water in the Gulf of Alaska, young Pacific cod in near shore safe havens where they typically spend their adolescence did not experience the protective effects those areas typically provide, a new study found.
