Many roads lead to Asia

Scientists discovered that Denisova hominins interbred with modern humans at least 44,000 years ago, contributing genetic material to populations in Southeast Asia and Oceania. The study suggests that there were at least two migration waves, contradicting previous assumptions about human settlement in the region.

Study puts a new spin on ibuprofen's actions

Researchers discovered that ibuprofen and other NSAIDs selectively block endocannabinoid metabolism, potentially leading to new analgesic medications with fewer side effects. This finding raises the possibility of targeting inflammation and pain without the gastrointestinal and cardiovascular risks associated with traditional NSAIDs.
