Ancient human foot bones shed light on how two species coexisted

Scientists have successfully sequenced the genome of the woolly rhinoceros, a species that has been extinct for thousands of years, from remains discovered in the stomach of a naturally mummified Pleistocene wolf pup. This significant finding sheds light on the dietary habits and ecological interactions of these ancient species during the Pleistocene epoch.

Genetic material from a woolly rhinoceros was recovered from the stomach of a mummified wolf pup that lived 14,400 years ago, providing new insights into the extinction of this iconic megafauna species. The discovery was made in Siberia, where researchers analyzed the remains of the two-month-old female wolf cub, revealing a piece of woolly rhino flesh.

Scientists have successfully sequenced the genome of the woolly rhino using a specimen preserved in Siberian permafrost, revealing insights into the extinction of this giant mammal. This high-quality genomic data provides a clearer understanding of the species' biology and the environmental factors that contributed to its decline.

Psychiatry has made significant strides in identifying objective biomarkers for mental illnesses such as anxiety and depression, marking a pivotal moment in the field. This breakthrough comes after decades of research aimed at providing clearer diagnostic tools for mental health conditions.

An analysis of growth rings in the leg bones of 17 Tyrannosaurus rex individuals indicates that these dinosaurs took approximately 40 years to reach full maturity, suggesting a slower growth rate than previously believed. This finding contributes to the understanding that T. rex may not represent a single species but rather a more complex evolutionary lineage.

Scientists have unveiled the most complete skeleton of Homo habilis, dating back over 2 million years, which exhibits features reminiscent of the famous fossil known as Lucy. This discovery marks a significant advancement in understanding early human ancestors and their physical characteristics.

Scientists have proposed that some of the over 6,000 exoplanets identified beyond our solar system may not be planets at all, but rather tiny black holes formed in the early universe. This hypothesis suggests a need to reevaluate how celestial objects are classified and understood.

Construction is responsible for 10 to 20 percent of global greenhouse gas emissions, prompting calls for a complete overhaul in building practices to maintain global temperatures below 2°C. Efficient design and sustainable materials are essential to mitigate the climate impact of urban development.
