Children exposed to high indoor levels of pet or pest allergens during infancy have a lower risk of developing asthma by 7 years of age, new research reveals. The findings may provide clues for the design of strategies to prevent asthma from developing.
Roughly 300,000 Texans living in impoverished border communities known as ‘colonias’ are facing substandard housing, lack of resources and exposure to toxic stress. New research finds these communities are also ill-equipped to face a natural disaster.
Thirdhand-smoke results when exhaled smoke and smoke emanating from the tip of burning cigarettes gets on surfaces such as clothing, hair, homes, and cars. Using a mouse model, researchers have found that thirdhand-smoke exposure has a significant effect on health, specifically the liver and brain, as early as one month after initiation of exposure — an effect that worsens with time.
Authors of a new report believe that theirs is among the first human studies to investigate the influence of phthalate exposure on sperm epigenetics, embryo development and whether DNA methylation in sperm cells may be a path by which a father’s environmental exposure influences these endpoints. DNA methylation, one mechanism of epigenetics, is a chemical tag on DNA that does not change the gene sequence but is involved in controlling gene expression.
Researchers have examined differences in the number, location, and magnitude of head impacts sustained by young athletes during various youth football practice drills. Such information could lead to recommendations for football practices, including modification of some high-intensity drills in order to reduce players’ exposure to head impacts and, consequently, lessen the risks of injury.
Scientists have long deemed the ability to recognize faces innate for people and other primates — something our brains just know how to do immediately from birth. However, the findings of a new study cast doubt on this longstanding view.
Researchers have unraveled the negative effects of pesticide exposure on birth outcomes, such as weight, gestation and abnormalities.
Exposure to environmental levels of triclocarban (TCC), an antibacterial chemical common in personal care products like soaps and lotions as well as in the medical field, can transfer from mother to offspring and interfere with lipid metabolism, new research shows.
Gestational exposure to airborne particles derived from diesel exhaust can modify DNA in utero and alter the expression of genes that potentially increase susceptibility to adult heart failure, suggests a study in mice.
Rhesus macaques previously infected with dengue or yellow fever viruses appear to be neither more nor less susceptible to severe infection with Zika virus, according to new research.
