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.

Black carbon sensor could fill massive monitoring gaps

Black carbon is up to 25 times more hazardous to human health than other airborne particles of a similar size. Standard sensors are expensive and burdensome, resulting in sparse coverage in regions infamous for poor air quality, such as the greater Salt Lake City area. A University of Utah-led study found that a portable, more affordable sensor recorded black carbon concentrations as accurately as the most widely used instrument for monitoring black carbon in real time. The portable sensor could help expand an accurate observation network to establish disease risk and create effective public health policies.

Obesity disrupts normal liver function in mice

Your liver plays a vital role in your metabolism, the biological process which converts food into energy. We know that being overweight can negatively affect metabolic activity, but not exactly how. To better understand this, researchers compared the livers of mice which were a typical weight with mice which were obese. They were surprised to find that biological regulation of metabolic activity, after a period of feasting and fasting, was reversed between them. In typical mice, allosteric regulation (the process which controls metabolism) was inhibited during feeding and activated when fasting. However, in obese mice, allosteric regulation increased during feeding and decreased when fasting.

Study of 1.2+M births reveals associations between excess heat exposure and preterm births

In the face of increasing temperatures globally, a new study of 1.2 million births over two decades has shown a strong association between the risk of pre-term birth and exposure to extreme hot temperatures in the third trimester of pregnancy. The data suggested that this association with extreme temperature might be reduced by the level of greenery in a pregnant person's residential surrounds. The findings suggest health services should consider preparing for an increase in preterm births as our climate warms.
