Is there an evolutionary reason for same-sex sexual behaviour?

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.

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.

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.

A recent report indicates that the world may face climate impacts sooner than anticipated, potentially costing trillions due to underestimated warming rates that threaten economic growth.

Pacific Islanders are facing severe challenges due to climate change, with extreme weather events leading to home loss and displacement. Those who remain are implementing innovative adaptation strategies to secure their futures amidst these escalating threats.

A recent study has revealed that Greenland sharks can survive for centuries despite having diseased hearts, characterized by significant aging markers such as severe scarring. This finding suggests that these deep-sea predators maintain their health and longevity despite the presence of heart disease.

Researchers have discovered that combining two types of quantum computing devices could significantly enhance the imaging of distant exoplanets, allowing for clearer and more detailed observations of these celestial bodies. This advancement is expected to improve the capabilities of astronomical studies.
