Saturday Citations: Prehistoric dentistry; sleep and aging; our photogenic sun
Recent scientific discoveries highlight the capabilities of prehistoric humans and the complexities of modern biology. A Neanderthal molar dating back 59,000 years shows evidence of dental treatment, suggesting advanced medical knowledge. Additionally, a record-breaking radio burst from the sun has been linked to a feature in its atmosphere, while research indicates that both insufficient and excessive sleep can accelerate biological aging.
- ▪A Neanderthal molar with a drilled hole indicates prehistoric dental treatment.
- ▪The record-breaking radio burst from the sun lasted 19 days, surpassing the previous record of five days.
- ▪Research shows that both too little and too much sleep can speed up aging in various organs.
