Researchers found that Neanderthals carried human DNA from a now-extinct lineage of early modern humans, which interbred with them in Eurasia over 250,000 years ago. The study reveals that approximately 6% of the Neanderthal genome was inherited from modern humans.
New research reveals that the northern elephant seal's reproductive and foraging success has been impacted by a population bottleneck, which nearly caused their extinction. The study found lower female and male reproductive success, as well as reduced dive performance in individuals affected by the bottleneck.
A new analysis of DNA from ancient modern humans in Europe and Asia has determined that Neanderthals interbred with modern humans from approximately 50,500 to 43,500 years ago. This period of interbreeding left Eurasians with many genes inherited from their Neanderthal ancestors.
Research suggests that people tend to consume more food during stressful events, linked to adverse metabolic outcomes. A recent webinar explores the limitations of traditional self-report scales and introduces objective measures of eating behavior.
A recent study has found that frogs retain a surprising number of light-sensing proteins, contradicting the hypothesis that they lost these genes through evolution. The researchers discovered that most modern frog species have all 18 ancestral nonvisual opsins and four of five ancestral visual opsins.
Researchers at Cornell University have developed an AI-powered ring that can track fingerspelling in American Sign Language (ASL) with high accuracy. The device, called SpellRing, uses micro-sonar technology to capture finger movements and predict ASL letters in real-time.
