Estudo com gêmeos mostra que a genética molda o sucesso mais do que a criação

Uma nova pesquisa de um grande projeto com gêmeos sugere que os genes desempenham um papel maior na determinação da educação, carreira e renda do que apenas o ambiente familiar. As descobertas vêm do acompanhamento de participantes dos 23 aos 27 anos e destacam o forte vínculo genético com o QI. Especialistas afirmam que os resultados desafiam suposições sobre o quanto a criação pode superar traços herdados.

Pesquisadores acompanharam cerca de 880 gêmeos por meio do projeto alemão TwinLife, comparando gêmeos idênticos, que compartilham todos os genes, com gêmeos fraternos, que compartilham cerca de metade. Os testes de QI realizados aos 23 anos previram fortemente o status socioeconômico quatro anos depois, com a genética respondendo por cerca de 75 por cento da variação do QI e de 69 a 98 por cento da conexão entre QI e status.

Brain scans and mouse studies point to two autism connectivity subtypes

A large study combining human brain imaging with data from genetically engineered mouse models has identified two recurring patterns of brain connectivity in autism—one marked by higher-than-typical connectivity and another marked by lower connectivity—each tied to different biological pathways, researchers report.

Genes account for half of human lifespan variation, study shows

Researchers at Israel's Weizmann Institute of Science have determined that genetics explain about 50% of differences in human lifespan, far more than previously estimated. The finding, published in the journal Science, challenges earlier views that placed genetic influence at 20-25% or less. By analyzing twin data and filtering out external death causes, the team uncovered this stronger hereditary role.

Study finds epigenetic traits break Mendel's genetic laws

A federally funded mouse study has revealed that some inherited traits follow non-Mendelian patterns through epigenetic changes. The research identified hundreds of unexpected DNA methylation events across generations. It also documented the first known natural paramutation in a mammal.

Study links daily mental sharpness to productivity gains

Researchers at the University of Toronto Scarborough have found that feeling mentally sharp on a given day can boost productivity by up to 40 minutes. The study, published in Science Advances, tracked university students over 12 weeks and connected clearer thinking to setting and achieving bigger goals. Factors like sleep and workload influence these daily fluctuations.
