Published Blood sausages and yak milk: Bronze Age cuisine of Mongolian nomads unveiled (via sciencedaily.com) Original source
Bronze cauldrons were used by the inhabitants of the Mongolian steppe around 2,700 years ago to process animal blood and milk. This is shown by a protein analysis of archaeological finds from this period.
Published 'Missing' early sea sponges discovered (via sciencedaily.com) Original source
Geobiologists reported a 550 million-year-old sea sponge that had been missing from the fossil record. The discovery sheds new light on a conundrum that has stumped zoologists and paleontologists for years.
Published Giant viruses found on Greenland ice sheet (via sciencedaily.com) Original source
Giant viruses found on the Greenland ice sheet probably regulate the growth of snow algae on the ice by infecting them. Knowing how to control these viruses could help us reduce the rate of ice-melt.
Published Using AI to decode dog vocalizations (via sciencedaily.com) Original source
Have you ever wished you could understand what your dog is trying to say to you? Researchers are exploring the possibilities of AI, developing tools that can identify whether a dog's bark conveys playfulness or aggression.
Published Gigantic Jurassic pterosaur fossil unearthed in Oxfordshire, UK (via sciencedaily.com) Original source
A team of palaeontologists has discovered a fossil of a gigantic flying reptile from the Jurassic period with an estimated wingspan of more than three metres -- making it one of the largest pterosaurs ever found from that era.
Published Captivating blue-colored ant discovered in India's remote Siang Valley (via sciencedaily.com) Original source
A new species of blue ant was discovered in Yingku village in Arunachal Pradesh, Northeastern India. It was named Paraparatrechina neela, after the word 'neela' which means blue in various Indian languages. Its unique blue coloration makes it stand out among other ant species.
Published Food drove the evolution of giraffes' long neck (via sciencedaily.com) Original source
A study explores body proportions of Masai giraffes, lending insight into why giraffes have such long necks and how this trait might have evolved.
Published How sharks survived a major spike in Earth's temperature (via sciencedaily.com) Original source
The sharks we know today as the open ocean's top predators evolved from stubby bottom dwellers during a dramatic episode of global warming millions of years ago.
Published An unlikely hero in evolution: Worms (via sciencedaily.com) Original source
One of Earth's most consequential bursts of biodiversity -- a 30-million-year period of explosive evolutionary changes spawning innumerable new species -- may have the most modest of creatures to thank for the vital stage in life's history: worms.
Published 'Ugly' fossil places extinct saber-toothed cat on Texas coast (via sciencedaily.com) Original source
This fossil looks like a lumpy, rounded rock with a couple of exposed teeth that are a little worse for wear, having been submerged and tumbled along the floor of the Gulf of Mexico for thousands of years before washing up on a beach. But when it was X-rayed a doctoral student saw there was more to the fossil that met the eye: a hidden canine tooth that had not yet erupted from the jaw bone. It was just what researchers needed to identify the fossil as belonging to a Homotherium, a genus of large cat that roamed much of the Earth for millions of years.
Published Scientists invent 'living bioelectronics' that can sense and heal skin (via sciencedaily.com) Original source
Reaserchers have created a prototype for what they call 'living bioelectronics': a combination of living cells, gel, and electronics that can integrate with living tissue. Tests in mice found that the devices could continuously monitor and improve psoriasis-like symptoms, without irritating skin.
Published Picture this: Snapping photos of our food could be good for us (via sciencedaily.com) Original source
Research reveals taking pictures of food isn't just content for our social media feeds, but could be the key to improving people's diets.
Published Chicken feathers to deliver chemotherapy drugs and repair enzymes (via sciencedaily.com) Original source
A new method of drug delivery using proline, an amino acid found in chicken feathers and skin tissue, could be used to limit the side effects of chemotherapy and repair important enzymes, new research suggests.
Published Acute sense of touch helps hummingbirds hover near a flower without bumping into it (via sciencedaily.com) Original source
Hummingbird flight mechanics have been well studied but far less is known about how their sense of touch helps them sip nectar from a flower without bumping into it. Most of what scientists know about how touch is processed in the brain comes from studies on mammals, but bird brains are very different from mammal brains. New research shows that touch and air pressure on the wings and legs activate specific clusters of neurons in two regions of the forebrain to create a map of their body, which may help hummingbirds make nuanced adjustments to flight.
Published Orchids support seedlings through 'parental nurture' via shared underground fungal networks (via sciencedaily.com) Original source
Orchid plants nurture their seedlings via an underground fungal network, new research has revealed.
Published Slugs and snails love the city, unlike other animals (via sciencedaily.com) Original source
Most native species avoid more urbanized areas of Los Angeles, but slugs and snails may actually prefer these environments, according to a new study.
Published The secret sex life of coral revealed (via sciencedaily.com) Original source
Corals play an essential role in ocean ecosystems, and like many organisms, they are under threat from climate change and other human activities. To better protect coral, it's first necessary to understand them, in particular their reproductive life cycle, which only happens once a year. For the first time, researchers have produced a model for coral spawning, based on various environmental factors. They achieved this by tapping an often overlooked source of aquatic knowledge, an aquarium.
Published Why do Dyeing poison frogs tap dance? (via sciencedaily.com) Original source
The toe tapping behavior of various amphibians has long attracted attention from researchers and pet owners. Despite being widely documented, the underlying functional role is poorly understood. In a new paper, researchers demonstrate that Dyeing poison frogs modulate their taps based on specific stimuli.
Published How killifish embryos use suspended animation to survive over 8 months of drought (via sciencedaily.com) Original source
The African turquoise killifish lives in ephemeral ponds in Zimbabwe and Mozambique. To survive the annual dry season, the fish's embryos enter a state of extreme suspended animation or 'diapause' for approximately 8 months. Now, researchers have uncovered the mechanisms that enabled the killifish to evolve this extreme survival state.
Published Florida fossil porcupine solves a prickly dilemma 10-million years in the making (via sciencedaily.com) Original source
An exceptionally rare fossilized porcupine skeleton discovered in Florida has allowed researchers to trace the evolutionary history for one of North America's rarest mammals.
