Smokers and people who recently quit are more likely to face complications after having an operation than non-smokers, a new study reveals.

Our immune systems weaken as we get older, making fewer cells that fight infection and help us recover from illness and injury. Scientists aren't completely sure why. They may have a better idea now, however, thanks to a new study in GeroScience.

New research to be presented at this year's European Congress on Obesity (ECO 2025, Malaga, Spain, 11-14 May) shows that women are much more aware of knowledgeable about the obesity drugs GLP-1/GIP receptor agonists (that include semaglutide and tirzepatide).

Research published in the Journal of Neurochemistry has detailed the role of a protein, hnRNP A1, in the formation and stability of myelin, suggesting an important impact on neurodegenerative diseases and mental disorders such as multiple sclerosis and schizophrenia.

Insomnia is a significant health and quality of life concern for older adults, with up to half of all adults over the age of 65 experiencing insomnia symptoms.

A new study led by researchers at Yale University suggests that early-life exposure to two widespread environmental pollutants- small particle air pollution and outdoor artificial light at night-could increase the risk of pediatric thyroid cancer.

A study published in the American Journal of Human Genetics by researchers at Baylor College of Medicine and the Jan and Dan Duncan Neurological Research Institute (Duncan NRI) at Texas Children's Hospital provides solutions to the pressing need to identify factors that influence Alzheimer's disease (AD) risk or resistance while providing an avenue to explore potential biological markers and therapeutic targets.

New research suggests that calming the brain's immune cells might prevent or lessen the damaging inflammation seen in Alzheimer's disease.

Global measles incidence, mortality, and DALY rates in children under five dropped significantly from 1990 to 2021. However, the COVID-19 pandemic disrupted vaccination efforts, leading to coverage declines and elevated outbreak risks in low-SDI regions.

A groundbreaking study published in the journal Current Neuropharmacology highlights a concerning potential link between Glucagon-like Peptide-1 (GLP1) receptor agonists-widely used in blockbuster drugs like Ozempic-and the risk of depression and suicidal ideation (SI).

How do we learn something new? How do tasks at a new job, lyrics to the latest hit song or directions to a friend's house become encoded in our brains?

Researchers led by Jean-Paul Noel at the University of Minnesota, United States, have decoupled intentions, actions and their effects by manipulating the brain-machine interface that allows a person with otherwise paralyzed arms and legs to squeeze a ball when they want to.

Preschool children aged 3–5 successfully used the Teddy the Bear pictorial scale to rate hunger before and after meals, supporting its validity for group-level research. However, younger children, especially three-year-olds, struggled more with using the tool accurately.

Researchers evaluated the safety and immune response of a poultry-derived H5N1 avian influenza vaccine in black vultures and critically endangered California condors. The findings support the use of vaccination as a conservation tool against deadly avian flu outbreaks.

Researchers from Children's Hospital of Philadelphia (CHOP) and the Perelman School of Medicine at the University of Pennsylvania (Penn Medicine) have successfully employed an algorithm to identify potential mutations which increase disease risk in the noncoding regions our DNA, which make up the vast majority of the human genome.

A recent study in the Journal of Nutrition Education and Behavior, published by Elsevier, explores the nutrition perspectives and attitudes of Ghanaian pregnant adolescents and adolescent mothers.

Hydroxyurea remains effective long-term in reducing emergency department visits and hospital days for children living with sickle cell disease (SCD), according to new research published in Blood Advances.

Cleft lip and cleft palate are among the most common birth defects, occurring in about one in 1,050 births in the United States.

A new discovery could pave the way for more effective cancer treatment by helping certain drugs work better inside the body.
