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.

The West is best to spot UFOs
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.

Does Russia stand to benefit from climate change?
There exists a narrative about climate change that says there are winners and losers -- with Russia being one of the countries that stand to benefit from its effects. In a new study, researchers found that Russia is suffering from a variety of climate change impacts and is ill-prepared to mitigate or adapt to those climate impacts. And, as the rest of the world transitions to renewable energy sources, Russia's fossil-fuel-dependent government is not willing or ready to make alternative plans for the country, changes that could potentially benefit the whole of their society.

Teachers' growth mindset appears more important than warmth
Students tend to like friendly teachers, but they like those who believe they can improve even more, new research indicates. Students in a study still responded positively to instructors described as being cold but who also had a growth mindset, meaning they felt students' ability in a subject could improve by working hard and trying different strategies. The opposite was also true: more participants reacted negatively to a warm, smiling teacher when they stated a fixed mindset, which is a belief that innate abilities cannot be changed, such as someone being naturally good at math.

Highways through historically redlined areas likely cause air pollution disparities today
As part of the New Deal, several governmental programs were created to expand homeownership through mortgages and loans. However, neighborhoods with primarily Black or immigrant communities often were rated 'hazardous' for repayment under the discriminatory, 'redlining' practice that restricted lending. Today, those same areas are exposed to more air pollution than other urban neighborhoods, and the cause could relate to nearby highways or industrial parks.

To boost a preschooler's language skills, consider reminiscing
Book sharing is a popular way parents engage young children in conversation. However, not all parents are comfortable with book sharing and not all children like having books read to them. Research provides an alternative. To boost the quality of a preschooler's language experience and skills, consider reminiscing with them. Findings show reminiscing is very good at eliciting high quality speech from parents, and in many ways, is just as good as book sharing (wordless picture books).

Why do(n't) people support being nudged towards healthier diets?
You may not realize it, but 'nudge' has been used by businesses, policy-makers and governments for years to prod the public into making different choices. Small changes in our environment can 'nudge' us into different behaviors without restricting the options available to us. For example, printing the low-calorie options in bold on a menu, or showing the calorie information, might change what we choose to eat. But does the public support this?

New study finds chemical composition of US air pollution changed over time
A new study analyzed space and time trends for fine particulate matter (PM2.5) in the continental United States to track the progress of regulatory actions by federal, state and local authorities aimed at curbing air pollution. The team found that while the annual average concentration for PM2.5 had been significantly reduced, its chemical composition had changed during the study period of 2006 to 2020. Their analysis suggests targeted strategies to reduce specific pollutants for different regions of the U.S. may be more effective in further reducing total air pollution and PM2.5 -related adverse health effects. PM2.5, an airborne pollutant, is a mix of multiple chemical species and includes fine particles less than 2.5 microns in size. PM2.5 has been linked to many adverse human health effects including premature death. It also can reduce visibility by creating haze in the air.

School uniform policies linked to students getting less exercise, study finds
School uniforms could be restricting young people from being active, particularly primary school-aged girls, according to a new study. The study used data about the physical activity of more than a million five-to-17-year-olds in 135 countries. In countries where a majority of schools require students to wear uniforms, fewer young people are meeting the World Health Organization's recommendations for physical activity (60 minutes per day). Fewer girls are meeting the guidelines than boys -- with a standard gap of 7.6 percentage points between boys and girls.
