New research reveals that a fundamental process in bacterial gene regulation called sigma cycle, long thought to involve the release of a key protein, sigma factor, might not be universal, opening new avenues for understanding and combating bacterial threats.

Researchers have identified proteins behind bacterial mutation, paving the way for a sustainable treatment to bacterial diseases.

Researchers from Bose Institute, Kolkata, investigated the effect of air circulation and the varying climatic conditions on the mustard aphids that migrate across the Indo-Gangetic Plains in Northern India. The authors traced the pests’ exact origin by studying the backward courses of air movement along known migratory routes.

Bacteria like Salmonella and Mycobacterium, which have developed resistance to multiple drugs, are now a global health challenge. Studies estimate that the number of people succumbing to infections caused by drug-resistant bacteria is on the rise, with 33,000 deaths annually in Europe alone.
