Some of the symptoms of neurodevelopmental disorders (NDDs) such as autism spectrum disorder and epilepsy may result from dysfunction of certain neurons in the brain and their ability to change their properties in response to experiences-a process called experience-dependent plasticity.

Ultra-processed foods (UPFs) account for nearly 60% of adults' and 70% of children's energy intake in the United States.

People with both atrial fibrillation and Alzheimer's disease who are treated with modern NOAC blood-thinning medicines may experience a slower rate of cognitive decline.

People with narrowing of the coronary arteries have low-grade, uncontrolled inflammation in the body, even if they are symptom-free and receiving optimal treatment.

In a recent Finnish study, more screen time since childhood was associated with better cognitive processing in adolescence.

For over 20 years, it has been a matter of dispute whether oxytocin bolsters trust. A new study conducted with the involvement of the University of Zurich now provides robust evidence that the hormone selectively increases trusting behavior in men with a low disposition to trust.

Early natural menopause is already associated with a higher long-term health burden. A new large-scale study demonstrates that cumulative social disadvantage-and in particular, unemployment-is strongly associated with an increased risk of all-cause mortality and cardiovascular disease, as well as a marked predisposition to dementia, in women with early natural menopause.

Young scientists who frequently handle laboratory chemicals and consume relatively few antioxidant-rich foods may be more likely to report symptoms such as fatigue, headaches, pallor, and easy bruising, according to a new study of university students in Nigeria.

A new study that explores gene expression during heart transplant rejection marks a step forward for precision medicine approaches to treat organ rejection.

Hearing impairment ranks as the third largest contributor to global disability among sensory disorders, with prevalence rising across younger and middle-aged populations alongside older adults.

Bedfont® Scientific Limited, a world leader in breath analysis, is excited to be attending this year's European Respiratory Society (ERS) Congress in Barcelona.

The DECAF randomized trial found that adults with persistent atrial fibrillation or atrial flutter assigned to drink at least one cup of caffeinated coffee daily had a 39% lower hazard of recurrent clinically detected AF or flutter than those assigned to avoid coffee and caffeine. The findings challenge longstanding advice to routinely restrict caffeinated coffee in people with AF, while further research is needed to determine whether coffee itself provides a protective effect.

Wiley, a global leader in authoritative content and research intelligence, today released the new edition of the Wiley Registry/NIST Mass Spectral Library, a reference database that combines two essential mass spectrometry references in a single, integrated collection, giving scientists the full depth of both to identify unknown chemical compounds.

A meta-analysis of eight prospective studies involving 143,380 participants found that higher nut consumption was associated with a lower risk of developing hypertension. Each 28 g/day increment was associated with a 20% lower relative risk in the linear analysis, while the modeled association appeared to level off at around one handful per day.

Several cannabinoids reduced chemotherapy- and radiation-induced apoptosis in glioblastoma cell models, with effects linked to reduced apoptotic priming, increased pro-survival signaling, and G1 cell-cycle arrest. The findings raise concern that cannabinoid exposure could interfere with some cancer treatments, although the results are limited to laboratory models and require in vivo and clinical validation.

Accelerated biological age in midlife was associated with higher risks of cardiovascular disease and death in both men and women over nearly three decades of follow-up. Women with accelerated biological age also showed a higher risk of dementia, although adding biological age to standard risk factors provided only minimal additional predictive value.

Higher screen use was not consistently associated with poorer psychosocial development across childhood and adolescence in a large Scottish cohort. Very high gaming at age 15 was linked to greater difficulties, while some social media use was associated with lower difficulties scores, although causality cannot be established.

Objective fitness testing in 13,423 older adults in Taiwan found that higher physical fitness was consistently associated with lower all-cause mortality over a median seven years. Balance and agility, lower-body strength, and cardiorespiratory fitness showed the strongest associations, while a composite fitness score produced the steepest mortality gradient.

Women with childhood overweight or obesity trajectories had lower hazards of childbirth from their mid-20s onward, with the strongest associations emerging after age 30. Childhood BMI trajectories were generally not associated with diagnosed infertility, suggesting that biological infertility alone may not explain the reduced childbirth rates.

An innovative youth mental health service model can improve care and ease pressure on Canada's health-care system, a new study led by researchers at McGill University and the Douglas Research Centre demonstrates.
