NASA is set to launch four astronauts on Artemis II, a 10-day crewed mission around the moon marking humanity's farthest spaceflight in 54 years and a critical step toward lunar surface landing before China.
Estudo Randstad revela que 21,3% da população empregada em Portugal pratica teletrabalho, totalizando 1,15 milhões de trabalhadores, com Grande Lisboa liderando a tendência a 34,5%.
A solar eclipse will be visible Wednesday across Europe and parts of the U.S., with totality in Iceland, Greenland, Russia, Spain, and Portugal. Northern U.S. regions will experience a partial eclipse.
Research reveals humans systematically misjudge probability distributions, favoring moderate structural complexity regardless of actual complexity. Eight behavioral experiments show this cognitive bias stems from memory limitations constraining internal model building.
Researchers reveal that parent-of-origin-specific 3D chromatin architecture regulates imprinted genes through allele-specific enhancer interactions and antisense transcription, with implications for understanding genomic imprinting mechanisms.
Researchers identify how ultraviolet-A exposure causes corneal endothelial cells to undergo polyploidization, initially protective but eventually leading to fibrosis in Fuchs endothelial corneal dystrophy. YAP1 inhibition shows promise as a therapeutic target.
Researchers successfully used CRISPR gene editing to remove the allergen-producing protein in dogs, creating two puppies that triggered no allergic reactions in human testing.
