Physical, social factors may together account for up to 9 times higher risk of faster brain ageing: Study
Publicado em 06 de abril de 2026
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 [...]

New Artificial Saliva Shows Promise for Protecting Teeth in Head and Neck Cancer Patients
Publicado em 05 abril 2026A significant breakthrough in dental health for patients undergoing treatment for head and neck cancer has been achieved with the development of a new type of artificial saliva. This innovative mouthwash utilizes a lab-modified sugarcane protein known as CANECPI-5, which has shown the potential to protect teeth from the detrimental effects of reduced saliva production—a common side effect of radiotherapy in this patient population. Research conducted at the Bauru School of Dentistry at the [...]SSBCrack News (Índia) -
Our environment shapes how fast the brain ages
Publicado em 03 abril 2026Aging is not just in our genes; our environments play a major role. A new large-scale study from the Global Brain Health Institute (GBHI) at Trinity College Dublin has found that the physical and social exposome, the total of our environmental exposures across our lifetimes, plays a major role in determining how our brains age. The researchers looked at data for 18,701 participants in 34 countries, including healthy people and those diagnosed with Alzheimer’s disease, frontotemporal lobar [...]Tech Explorist (Índia) -
Chimpanzees began picking out crystals from ordinary rocks and carrying them to their beds until researchers realized they wouldn’t give them back without something in return
Publicado em 30 março 2026We have been studying our closest primate cousins to better understand ourselves. One recent finding has detailed how chimpanzees prefer crystals to normal rocks. But science has struggled to understand why, until now. By studying chimpanzees and apes, we reveal a few secrets about ourselves. What makes these chimps hold on to their favorite crystals? How studying chimps and apes has revealed and explained human mysteries Some scientists have dedicated their lives to studying apes and [...]GreenStories (Índia) -
Ancient Sauropods' Unique Ability to Stand Upright Explained by New Study
Publicado em 30 março 2026Around 66 million years ago, two distinct types of long-necked, four-legged dinosaurs emerged, notable for their unique capability to rise on their hind legs and maintain this posture for extended periods. This adaptation likely enabled them to access foliage high in trees and may have enhanced their size, making them more intimidating to potential predators. The two species under study, the Brazilian Uberabatitan and the Argentine Neuquensaurus, were comparable in size to modern elephants. [...]SSBCrack News (Índia) -
Is Your Breathing Pattern Causing Your High Blood Pressure?
Publicado em 24 março 2026New research shows that brain cells controlling exhalation can tighten (constrict) blood vessels and cause high blood pressure (hypertension).This discovery explains why 40% of people with hypertension do not respond to standard medication and reveals a new target for treating chronic hypertension.(1) The findings were demonstrated by researchers from the University of São Paulo (USP) in Brazil, and published in the journal Circulation Research. Using animal models (mice), the [...]Medindia (Índia) -
High blood pressure: Hidden region in brain that controls how you breathe out can cause hypertension
Publicado em 24 março 2026High blood pressure may be linked to a small brain region Treating neck sensors could help control blood pressure safely Strong breathing patterns may raise blood pressure levels Hight blood pressure is one of the biggest health problems all over the world. It happens when the force of blood in your body is too high or too low. It can be caused by stress, unhealthy food, and less exercise. Many people don’t notice the symptoms of high blood pressure, and that is why regular checkups [...]moneycontrol.com (Índia) -

Global Oceans Saturated with Human-Made Chemicals, Major Study Reveals
Publicado em 23 março 2026A major study led by Kalinski and Petras reveals human-made chemicals are deeply embedded across global oceans, significantly altering marine chemistry. Analyzing 2,315 seawater samples, the research found industrial pollutants, previously rarely monitored, are far more abundant and widespread than recognized. These xenobiotics impact marine microbial processes and the ocean’s carbon cycle, with unknown long-term ecological consequences. The study underscores the urgent need for standardized [...]DPRJ Universal (Índia)
