A new study found that low-income boys' inattention in kindergarten is associated with lower earnings 30 years later, while prosocial behavior is linked to higher earnings. The research followed 920 boys from low-income neighborhoods and found that teachers' ratings of inattention were a significant predictor of adult earnings.
Researchers found that adolescent adenoids and tonsils do not shrink significantly during teenage years, contradicting previous medical consensus. This challenges existing guidelines for respiratory complications like obstructive sleep apnea, potentially leading to changes in surgical procedures.
A new study found that school suspension and expulsion are more effective predictors of youth drug use than police arrests, particularly among minority youth. The research suggests that removing students from school can facilitate drug use due to lack of supervision, whereas being arrested does not necessarily lead to drug use.
A new study reveals an association between hearing loss and higher risk of subjective cognitive concerns, suggesting early stage changes in cognition. Men with mild, moderate, or severe hearing loss experienced a 30%, 42%, and 54% increased risk of cognitive decline compared to those with no hearing loss.

Babies younger than 6 months fail to recognize their mothers' faces when watching mobile phones, but improve face recognition at around 5.5 months through increased brain activity in response to profile views. Longitudinal testing of 14 babies from 3-8 months old provided key insights into developmental changes in face recognition skills.

Adults who consume large amounts of sugary beverages have a higher risk of dying from heart disease or other causes compared to those who drink fewer sugary drinks. The study found a graded association between consuming more sugary beverages and an increased risk of death, with those in the top 25% having twice the risk as those in the...
The Great Recession of 2008 was associated with significant increases in blood pressure and fasting blood glucose levels, especially among vulnerable populations. Stress and medication use changes during the recession likely contributed to these health effects.

A new study of 5,000 older people in the UK found that those with diabetes experience steeper rates of cognitive decline compared to those with normal blood sugar control. The study suggests that efforts to delay diabetes onset and control blood sugar levels may prevent subsequent progression of brain function decline.

Daily outings facilitated exposure to beneficial experiences and allowed resilient individuals to remain engaged despite physical limitations.
A University of Oregon study found that bilingual preschoolers develop faster inhibitory control skills than monolingual peers. The research used a longitudinal approach to examine the effects of bilingualism on executive function development in low-income children.
A large Canadian study links e-cigarette use among high school students to later cigarette smoking. The study found that youth who used e-cigarettes were more likely to start and continue smoking cigarettes. However, the association may be due to common factors rather than a causal effect.
A study published in Scientific Reports found that city dwellers living close to a forest showed healthier amygdala structures, suggesting better stress coping mechanisms. However, the association with urban green or wasteland was not confirmed.

The technology allows for longitudinal studies of the same animal during the course of the infection, providing enhanced information about disease progression.
A recent study found a 37% increase in the gap between the average lifespan of people with schizophrenia and the general population. Longitudinal studies suggest that this widening trend is due to factors such as inadequate healthcare, unhealthy lifestyles, and biological aging.
Studies suggest having an obese spouse substantially increases a man's risk of developing type 2 diabetes, while women with an obese partner are not at increased risk. The research highlights the importance of screening spouses for diabetes if obesity is found in one person.

Research from Association for Psychological Science reveals that women living in gender-equal societies outperform men on cognitive tests later in life. The study also found that changes in gender-role attitudes within a country over time are associated with improvements in women's cognitive performance.
A University of Central Florida study found that individuals with the Apolipoprotein-E4 gene variant have a 20% greater chance of developing clinically significant depressive symptoms. The research suggests that both ApoE4 and poor vascular health independently increase depression risk, not a compounded effect.
This longitudinal study found that early family relationships significantly impact children's emotional development, particularly in terms of emotion regulation. Problematic family types were associated with increased depressive symptoms and biases in social-emotional information processing. The study suggests that strengthening emotio...
A new study published in Pediatrics found that children with cochlear implants who received limited or no sign language exposure had better outcomes in speech perception, speech intelligibility, language, and reading. The study suggests that oral communication may be more beneficial for young cochlear implant recipients.
A University of Waterloo study of 1170 adults aged mid-40s to mid-70s found that those closer to their chronological age reported lower quality sex lives. Feeling younger at heart was associated with increased interest in sex, particularly for middle-aged and older individuals.
A longitudinal study of over 4,000 US teens found that honesty with parents is linked to lower risk of drinking and addiction. Excessive parental control can actually increase the likelihood of teenage lying and drinking.
A recent study analyzed over 9,000 middle-aged adults in England and found that moderate drinkers who also smoked experienced more health problems than those who drank lightly or abstained. The researchers suggest that other lifestyle factors, such as education and smoking habits, may be more influential on midlife health.
A University of Colorado Boulder study compares domestic extremists to street gang members, finding significant differences in age, education level, religiosity, and ethnicity. The research also suggests that policies targeting gangs may not be effective for countering domestic extremism.
A new Penn study found that early-maturing girls are more likely to experience physical or sexual violence in dating relationships if their friend group contains more boys. The research, published in Pediatrics, analyzed data from over 3,800 girls and confirmed that girls who developed earlier have a 14% increased risk of dating abuse.
African-Americans experience a drop in systolic blood pressure when moving to less segregated neighborhoods, with reductions ranging from 1-5 points. The study suggests that less stress and better access to resources contribute to the decrease in blood pressure.
A nationwide study found middle-income Americans were most likely to eat fast food, with rich people also consuming fast food regularly. The study also showed that people with changing income levels didn't alter their eating habits, and heavy users of fast food often have less leisure time.

The research also identified risk factors for joblessness and highlighted the need for occupational rehabilitation strategies to support survivors' return to work.
A University of Washington study found that married LGBT older adults have better physical and mental health, more social support, and greater financial resources than their single counterparts. The study also highlights the importance of understanding individual choices regarding marriage within the LGBT community.
A comprehensive neuropsychological study of retired professional hockey players found they reported cognitive and psychosocial challenges, despite performing well on objective tests. The study suggests a link between concussion history and executive functioning, and genetic factors may play a role in psychiatric symptoms.
