Even though they encounter multiple classmates during school each day, primary school children are much more likely to become friends with classmates they sit next to rather than other children in the class, a study funded by the National Institutes of Health suggests. The results imply that by assigning seats, teachers have a disproportionate influence on the friendships their students form.

Science Update: Pfizer, Moderna COVID-19 vaccines may offer slightly greater protection during pregnancy than Johnson & Johnson vaccine, NIH-funded study suggests
The Pfizer-BioNTech and Moderna COVID-19 vaccines may offer slightly more protection during pregnancy against SARS-CoV-2, compared to the Jansen/Johnson & Johnson vaccine, suggests a study funded by the National Institutes of Health. Vaccination during the first and third trimesters appears to result in higher antibody-stimulated immune responses than vaccination in the second trimester. It also may lead to greater transfer of antibodies from maternal blood to the placenta.
Science Update: Online tool helps protect adolescents from stress, NIH-funded study suggests
A 30-minute, self-administered online training module can protect adolescents from unhealthy responses to stress and related mental health consequences, suggests research funded in part by NICHD.
Director's Corner: Preventing Gun Violence, the Leading Cause of Childhood Death
In 2020, firearm-related injuries surpassed motor vehicle crashes to become the leading cause of death among children and adolescents in the United States. Dr. Bianchi highlights NICHD-supported research to prevent firearm violence and reduce the related deaths, injuries, and trauma.
Science Update: Hormone prevents obesity in offspring of pregnant mice with obesity, according to NIH-funded study
Giving the hormone adiponectin to pregnant mice with obesity prevented later life obesity and related health conditions in their offspring, according to a study funded by the National Institutes of Health. The findings suggest that adiponectin, a hormone produced by fat cells, could play a role in reducing the lifelong obesity risk of children born to mothers with obesity during pregnancy.
Item of Interest: NICHD recognizes updated safe infant sleep recommendations
The Safe to Sleep® campaign, a national effort to raise awareness about ways to reduce the risk of Sudden Infant Death Syndrome (SIDS) and other sleep-related infant deaths, will be updating the campaign’s messages to reflect revised recommendations for safe infant sleep issued by the American Academy of Pediatrics (AAP). The updates ensure that parents and caregivers have the latest information about evidence-based risk-reduction strategies.
Science Update: Placental inflammation could explain link between air pollution and pregnancy complications, NIH-funded study in mice suggests
The increase in pregnancy complications linked to air pollution exposure could result from the pollutants’ direct effects on the placenta, suggests a study in mice funded by the National Institutes of Health. Placentas of mice exposed to a mixture of common urban air pollutants before and during pregnancy were inflamed and had a loss of blood vessel cells. The study authors say the findings could provide insight into how air pollution might affect pregnancies and lead to strategies for preventing pregnancy complications.
Science Update: Placental genetic material in maternal blood could potentially diagnose gestational diabetes early, small NIH-funded study suggests
A new method to detect genetic material from the placenta in the blood of pregnant people could potentially identify the risk for gestational, or pregnancy-related, diabetes in the first trimester, suggests a small study funded by the National Institutes of Health.
Director's Corner: Visualizing The Placenta, a Critical but Poorly Understood Organ
The placenta supports pregnancy and influences the lifelong health of both mother and child. Yet it is the least understood, and least studied, of all human organs. In a guest post for the NIH Director’s Blog, Dr. Bianchi discusses work from NICHD’s Human Placenta Project to understand how the placenta functions in real time during pregnancy.
Media Advisory: Changes in brain’s visual areas in infancy may precede autism diagnosis
Infants who were diagnosed with autism spectrum disorder (ASD) at 24 months old had differences in the visual processing areas of the brain that were apparent at 6 months old, according to a study funded by the National Institutes of Health. The researchers theorized that disruption in visual processing could interfere with how infants see the world around them, changing how they interact with and learn from caregivers and their environment. These early changes could affect further brain development and play a role in ASD symptoms.
Media Advisory: Depression, loneliness associated with increased hospitalization risk after COVID-19, NIH-funded study suggests
People who reported in survey that they felt worried, depressed or lonely had a greater chance of being hospitalized after a COVID-19 diagnosis, suggests a study funded by the National Institutes of Health.
Science Update: Computerized assessment may identify new drivers at risk for unsafe driving, NIH-funded study suggests
New drivers who performed poorly on a computerized driving simulator were more likely to fail their road test, according to a study funded by the National Institutes of Health. The findings suggest that the virtual driving assessment—which mimics situations in which new drivers are more likely to crash—can identify drivers lacking the skills to avoid crashes so they can benefit from interventions on how to reduce their crash risk.
Science Update: Youth suicides increased in first year of the pandemic, NIH-funded study suggests
The stresses of the pandemic may have contributed to an increase in adolescent suicides, suggests a study of 14 states funded by the National Institutes of Health. Although the number and proportion of youth suicide varied among individual states, when all the states were considered together, researchers saw an increase in the number of suicides among youth 10 to 19 years of age and in the proportion of youth suicides compared to the overall population.
Science Update: NIH-funded researchers develop non-surgical method to treat endometriosis
Technique adapted from cancer treatment shows promise in mouse study.

Science Update: Scientists develop noninvasive method to predict congenital CMV infection
Researchers have developed a calculator to estimate the risk that cytomegalovirus (CMV) will pass to a fetus during pregnancy. By offering a noninvasive way to predict the chance of congenital CMV based on individual characteristics, this tool may help healthcare providers counsel pregnant people with CMV.
Science Update: COVID-19 vaccine appears to be safe after MIS-C, small NIH-funded study suggests
Vaccination against COVID-19 appears to be safe for children who have had multisystem inflammatory syndrome in children (MIS-C) and does not appear to increase the risk for inflammation of the heart or other organs, suggests a small study funded by the National Institutes of Health. MIS-C, a serious inflammation of the heart, lungs, kidneys, brain, skin, eyes, gastrointestinal organs or other body parts, occurs in children about 4 to 6 weeks after COVID-19.
Science Update: Digital tool to increase youth HIV testing shows promise in NIH-funded study
Youth aged 13 to 24 years who were offered HIV testing by a digital health tool on a tablet computer were at least as likely to accept as those who were offered testing face-to-face, according to an NICHD-funded study.
Science Update: Fertility treatments may increase risk for preterm birth, NIH-funded study suggests
Infertility treatments with ovulation drugs or intrauterine insemination—in which sperm is placed directly into the uterus—are associated with a higher likelihood of preterm birth, suggests a study funded by the National Institutes of Health.
Director's Corner: The Power of Networks
Clinical research networks bring together scientists, clinicians, and community stakeholders to identify important clinical questions and design and conduct high-quality studies to answer them. Scientific evidence generated by such studies can impact clinical care, as several recent findings from NICHD’s networks demonstrate.
