Amid confusion over US vaccine recommendations, states try to 'restore trust'

Crossing a room shouldn't feel like a marathon. But for many stroke survivors, even the smallest number of steps carries enormous weight. Each movement becomes a reminder of lost coordination, muscle weakness, and physical vulnerability.

United States President Donald Trump this week claimed children should not be vaccinated against hepatitis B until they are 12 years old, rather than at birth. He also said the viral liver infection was a sexually transmitted disease.

United States President Donald Trump recently claimed that using the common painkiller acetaminophen (also known as paracetamol and by the brand name Tylenol in the US) during pregnancy is fueling the rise in autism diagnoses. He then went on to suggest pregnant women should "tough it out" rather than use the common painkiller if they experience fever or pain.

Why do some people remain healthy through childhood yet become more vulnerable to brain disorders such as dementia later in life? A KAIST-led team has uncovered a key part of the answer: a developmental "switch" in astrocytes—the brain's most abundant support cells that shapes how strongly the brain's immune system reacts in adulthood.

A study published in Nature Communications describes how lymphatic endothelial cells assist in generating robust immune memory, offering new insights into how the immune system functions.

New research has found that newborns exclusively fed colostrum, the breastmilk produced in the first 72 hours following birth, were five times less likely to develop a peanut allergy by 12–18 months, and 11 times less likely to develop multiple food allergies, such as egg or cow's milk, compared with infants who also received formula during that period.

When a new immunization to protect newborns from respiratory syncytial virus (RSV) became available in late 2023, pediatricians at Temple University Hospital noted an unusually strong early interest from parents.

Weight-related peer teasing is a strong predictor of disordered eating behaviors in adolescents, particularly those at higher genetic risk, new research shows.

Meningococcal B cases have dropped by more than 70% in the five years since the South Australian Government introduced a publicly funded vaccination program, new data from the University of Adelaide has found.

Researchers at Children's Hospital of Philadelphia (CHOP) found that combining a specialized diet with an approved medication interrupts the growth of high-risk neuroblastoma, a deadly pediatric cancer, by reprogramming tumor behavior. The findings were published in the journal Nature.

Fluctuations in brain activity, also known as neural variability, enable us to be flexible in adjusting our behavior to the current situation. A new study shows that neural variability increases throughout development before stabilizing in adolescence. And deviating from this trajectory is associated with worse executive functioning. The study was published Sept. 17 in Neuron.

People who suspect that their sense of smell has been dulled after a bout of COVID-19 are likely correct, a new study using an objective, 40-odor test shows. Even those who do not notice any olfactory issues may be impaired.

A new study led by the Icahn School of Medicine at Mount Sinai offers one of the most comprehensive views yet of how brain cells interact in Alzheimer's disease, mapping protein networks that reveal communication failures and point to new therapeutic opportunities.

A new study in mice reports that concussions sustained early in life can cause subtle brain changes that re-emerge later in life. The findings, published in Experimental Neurology, may have significant implications for understanding the long-term impact of head injuries in children.

A new study from University Hospitals Connor Whole Health found that music therapy interventions involving singing, active instrument play, and relaxation/imagery may be more effective for reducing pain intensity than receptive interventions only involving live or recorded music listening among hospitalized patients with moderate-to-severe pain. The findings from this study were recently published in The Journal of Pain.

Researchers at the University of Waterloo have developed a better way to enhance the clarity and detail of eye images used to diagnose disease by teaching artificial intelligence (AI) software the science behind the imaging process.

Chest pain ranks as the second most common reason for emergency department (ED) visits, making it a key concern for patients and doctors. However, 80% of these cases are considered low-risk and not related to heart disease, and for these patients, anxiety and panic disorders are frequent diagnoses.

Building on her previous research into maternal and infant health during pregnancy and after birth, epidemiology associate professor Nansi Boghossian has published new findings in JAMA.
