Hypertrophic cardiomyopathy: Unlike global cohorts, South Indians carry different pathogenic genetic signatures

Compared with global cohorts (43.23%), South Indian patients had fewer variants (15.77%) in the 12 definitive genes linked to hypertrophic cardiomyopathy, which is a major cause of sudden cardiac deaths in young athletes. Instead, a single gene (MYH6) from the limited and disputed genes category had higher prevalence of pathogenic variants in South Indian patients

Risk to male fertility: Common parasite Toxoplasma gondii found to decapitate human sperm

After only five minutes of direct contact between Toxoplasma gondii tachyzoites and sperms, 22.4% of spermatozoa were headless, compared with just 1.6% in controls. By 10 minutes, the proportion of headless sperm became fourfold relative to controls, and by 15 minutes, it had increased eightfold. Many sperm developed twisted, rolled, or shortened tails, impairing their motility

Miyawaki forests in urban India are effective for carbon sequestration

While the criticism about high tree density per sq. metre in Miyawaki forests is partly valid, the vertical growth due to high density is not inherently unnatural or detrimental, but rather mirrors early-stage dynamics of natural forest regeneration, and may even enhance carbon sequestration and canopy formation in the short term

Curiouscity Science Discovery Centre: Where science becomes fun

With over one lakh visitors to date, the Bengaluru-based Curiouscity’s science centre has exhibits and experiments for children aged 8-15 years that have been designed by experts from IITs, IISc and Cornell, and facilitated by trained guides. It takes at least three hours to fully cover the centre and interact with the models
