People Are Still Being Exposed to Chemicals Banned 2 Decades Ago - ScienceAlert

A creator with experience tracking methane at landfills is drawing attention to a less flashy climate measure: fixing leaks from oil, coal, and gas infrastructure. In a TikTok video, Alaina Wood (@thegarbagequeen) presented methane leak repairs at fossil fuel sites as a fast way to cut emissions.

The angle and force of the blow would have likely severed arteries and pierced a lung. A small puncture wound through a 75,000-year-old Neanderthal shoulder blade may be the earliest evidence of death by spear on humanity’s family tree. Given forensic details such as the entry angle and overall damage, researchers believe the injury was made as an intentionally fatal “heart shot” that killed the ancient hominin within moments. The discovery is detailed in a study published today in the journal Scientific Reports.
