'Impossible' black hole collision pushed relativity to its breaking point — and scientists finally understand how

Scientists have determined that kissing has existed for at least 16 million years. This finding highlights the long evolutionary history of this behavior, suggesting that it may have deep roots in human and primate ancestry.

Scientists have traced the origins of kissing back to a primate ancestor that lived approximately 21 million years ago. This research sheds light on the evolutionary roots of this behavior, linking it to the common ancestor of humans and other large apes.

Scientists are warning that societies are not adequately prepared for the humanitarian and social costs associated with climate overshoot. While there has been significant progress in understanding the physical impacts of climate change, the authors emphasize the urgent need to focus on the broader implications for human welfare and social structures. This lack of preparedness could exacerbate existing vulnerabilities and lead to severe consequences for communities worldwide.
