A 66-million-year-old feather was found inside dinosaur poop; it may explain how birds survived the asteroid that killed the dinosaurs

Tyrannosaur preying on an ancient diving bird (Representational AI photo) A 66-million-year-old feather found inside fossilised dinosaur poop may offer a clue to why some birds survived the asteroid impact that wiped out most dinosaurs. Scientists say the feather belonged to a hesperornithiform, an extinct group of aquatic birds that lived alongside dinosaurs.The feather was…

Scientists used centuries-old aurora sightings to reconstruct 8 solar cycles from 1560 to 1640; their method placed solar minima within 2 years with more than 90% reliability

Centuries-old reports of strange lights in the night sky have helped scientists reconstruct a missing chapter in the Sun’s history. A study published in Scientific Reports by Kristof Petrovay, Laura G. Magyar and Hisashi Hayakawa has reconstructed eight solar activity cycles between 1560 and 1640 using historical records of aurorae, offering a way to trace…

A man climbed inside a giant Roman storage jar around 1,600 years ago and never came out; archaeologists think they know what he was hiding from

More than 1,600 years ago, as fire engulfed a Roman settlement in what is now Bulgaria, a young man appears to have made a desperate decision: he climbed inside a huge storage jar and hid. He never came out. Archaeologists uncovered his remains inside the vessel during excavations at the ancient Roman colony of Deultum…

In the 1850s, pigs brought to Santa Cruz Island became feral; golden eagles drawn by piglets helped drive foxes down 95%, then 5,036 pigs were removed as foxes rebounded to 1,300+

An ambitious conservation project off the coast of California has helped save the endangered Santa Cruz Island fox from near extinction. The rescue effort involved removing 5,036 feral pigs, allowing the native island fox (Urocyon littoralis santacruzae) population to recover from fewer than 100 animals to more than 1,300 across the 96-square-mile island. According to…

For decades, scientists thought North America had its own cheetah; ancient DNA reveals the extinct cat split from the puma lineage 2.6 million years ago

Representative Image (AI-generated) Its appearance told one story; its DNA tells another. For decades, the extinct Miracinonyx trumani was known as the “American cheetah” because its long legs, slender body and adaptations for speed made it look remarkably similar to Africa’s modern cheetahs. But a new genetic study has overturned that long-held picture. Published in…

Scientists built a system that watches activity across nearly every cell of a living vertebrate at once; transparent zebrafish revealed body-wide signals moving between organs

The system is called WHOLISTIC, short form for Whole Organism Live Imaging System for recording Tissue and IntraCellular activity. The body is never truly quiet. Even when an animal appears to be resting, billions of cells are sending signals, responding to changes and coordinating with organs far beyond their immediate surroundings. For scientists, the challenge…

Food and water feeding centres for wild birds can highly increase the risk of a deadly parasite |

A busy bird feeding station. Image Credit: Tim Felce/Wikimedia Commons Food and water stations intended to help wild birds may also help a potentially deadly parasite spread between species, according to a study published in Molecular Ecology. Researchers found that Trichomonas gallinae, a parasite that causes trichomonosis, was widespread among birds and in shared food…
