Your surroundings may be making your brain age faster, according to a new global study. Researchers from the Global Brain Health Institute (GBHI) at Trinity College Dublin have found that a mix of everyday physical and social exposures, from air pollution to inequality, could raise the risk of accelerated brain ageing. The researchers in the study titled The exposome of brain aging across 34 countries, published in Nature Medicine, say that when these physical and social exposures combine, [...]

A recent study in Nature Medicine highlights how the exposome significantly influences accelerated brain aging. Researchers found that cumulative environmental and social stressors can increase aging risk by up to nine times. Consequently, clinicians must look beyond individual biology to understand cognitive decline. Linking Exposome to Accelerated Brain Aging The study analyzed data from over 18,000 individuals across 34 countries, including India. Physical exposures like air pollution [...]

A promising breakthrough in the paper industry is emerging as researchers explore the use of fungal enzymes as an alternative to traditional chemical processes. These naturally derived enzymes have the potential to significantly reduce the industry’s reliance on harsh chemicals, making production more sustainable and environmentally friendly. The enzymes, produced by specific strains of fungi, can effectively break down lignin—the complex polymer that binds cellulose fibers in wood. [...]

A new artificial saliva made from a sugarcane protein may protect teeth from acid damage and decay. Saliva plays an important role in protecting teeth and controlling bacteria. In some patients, especially those receiving head and neck cancer treatment, saliva production is reduced, leading to a higher risk of tooth damage. A study published in the Journal of Dentistry aimed to develop an artificial saliva that can protect teeth and reduce bacterial activity. Researchers created a [...]

New Delhi: Physical and social exposures, including air pollution, extreme temperatures, lack of green spaces and socioeconomic inequality, could together account for up to a nine times higher risk of accelerated brain aging, according to an analysis. The study, published in the journal Nature Medicine, identified distinct but complementary brain markers -- physical exposures such as increased pollution and lack of green spaces were primarily associated with structural brain aging, affecting [...]

A major international study led by the Global Brain Health Institute and Trinity College Dublin, published in Nature Medicine, reveals that brain aging is not shaped by a single factor—but by a complex interaction of environmental, social, and political conditions. Analyzing data from 18,701 individuals across 34 countries, researchers explored the concept of the exposome—the total set of environmental and social influences a person experiences throughout life. They found that these [...]
