Researchers at IIT-Guwahati have identified a type of blue-green algae (cyanobacteria) that can effectively remove lead from contaminated water. The study highlights the role of exopolysaccharides (EPS) produced by the algae in absorbing lead, with laboratory experiments showing up to 66.2% removal. This discovery offers a promising, naturally abundant solution for water purification, though further validation is needed before commercial application.

Researchers have found that brainwave synchrony between individuals can be used to guide and improve social interactions, potentially "engineering" social connectedness. Studies involving thousands of participants, including collaborations with musicians and artists, demonstrated that being "on the same wavelength" is linked to healthy social relationships and can be boosted through interventions. This phenomenon, termed 'social synchrony', aligns brain, body, and language rhythms, playing a crucial role in social cohesion and learning.
