Scientists propose plan to determine if Planet Nine is a primordial black hole
Scientists have developed a new method to find black holes in the outer solar system, and along with it, determine once-and-for-all the true nature of the hypothesized Planet Nine.
Like humans, beluga whales form social networks beyond family ties
A groundbreaking study is the first to analyze the relationship between group behaviors, group type, group dynamics, and kinship of beluga whales in 10 locations across the Arctic. Results show that not only do beluga whales regularly interact with close kin, including close maternal kin, they also frequently associate with more distantly related and unrelated individuals. Findings will improve the understanding of why some species are social, how individuals learn from group members and how...
Care for cats? So did people along the Silk Road more than 1,000 years ago
Common domestic cats, as we know them today, might have accompanied Kazakh pastoralists as pets more than 1,000 years ago. This is indicated by new analyses done on an almost complete cat skeleton found during an excavation along the former Silk Road in southern Kazakhstan. An international research team has reconstructed the cat's life, revealing astonishing insights into the relationship between humans and pets at the time.
A tiny ancient relative of dinosaurs and pterosaurs discovered
Dinosaurs and pterosaurs may be known for their remarkable size, but a newly described species that lived around 237 million years ago suggests that they originated from extremely small ancestors. The fossil reptile, named Kongonaphon kely, or 'tiny bug slayer,' would have stood just 10 centimeters tall. The study may help explain the origins of flight in pterosaurs, the presence of 'fuzz' on both pterosaurs and dinosaurs, and other questions about these charismatic animals....
New connection between the eyes and touch discovered
Tiny eye movements can be used as an index of humans' ability to anticipate relevant information in the environment independent of the information's sensory modality.
