Recent research indicates that Greenland's unique genetic makeup stems from its original Inuit settlers, a small group of fewer than 300 individuals arriving from Siberia. Over a millennium, they developed specific gene variants suited for Arctic survival, such as those aiding in metabolizing seal and whale meat, but also harboring harmful recessive genes linked to certain diseases. Additionally, a significant survey highlights that about 40% of US scientists in their 70s prefer to keep working to maintain their professional identities, which may hinder new entrants into the field and affect retirement dynamics.
