Early vocabulary size is genetically linked to ADHD, literacy, and cognition

Are genetic factors underlying children's language development linked to later-life outcomes? In a genome-wide analysis, an international research team found genetic associations between children's early vocabulary size and later-life ADHD, literacy, and general cognition. These associations changed dynamically across the first three years of life. Both producing more words in infancy and understanding fewer words in toddlerhood were associated with a higher risk of ADHD.

Researchers identified environmental factors that explain why reports of Unidentified Anomalous Phenomena (UAP) are more common in certain regions of the country. Most sightings occur in the American West where proximity to public lands, dark skies and military installations afford more opportunities to see strange objects in the air. Understanding the environmental context of these sightings will make it easier to find explanations for their occurrence and help identify truly anomalous objects that may be a legitimate threat.

Climate change shrinking fish

Fish weight in the western North Pacific Ocean dipped in the 2010s due to warmer water limiting food supplies, according to a new study. Researchers analyzed the individual weight and overall biomass of 13 species of fish. In the 1980s and 2010s, the fish were lighter. They attributed the first period of weight loss to greater numbers of Japanese sardine, which increased competition with other species for food. During the 2010s, while the number of Japanese sardine and chub mackerel moderately increased, the effect of climate change warming the ocean appears to have resulted in more competition for food, as cooler, nutrient-dense water could not easily rise to the surface. These results have implications for fisheries and policymakers trying to manage ocean resources under future climate change scenarios.
