Honey bees perform their waggle dance more precisely when more hive mates watch, according to a new study. Researchers found that dancers adjust their movements to attract followers, sacrificing accuracy for engagement when audiences are small. The findings highlight the social dynamics of bee communication.

A team led by David Julius, the 2021 Nobel Prize winner in Medicine, has described the molecular mechanism by which intestinal tuft cells signal the brain to suppress appetite during parasitic infections. Published today in Nature, the study identifies communication via acetylcholine and serotonin that activates the vagus nerve. The finding could aid treatments for conditions like irritable bowel syndrome.

Scientists at Arizona State University have identified two unexpected ways bacteria can spread without their usual flagella structures. In one study, E. coli and salmonella use sugar fermentation to create fluid currents for surface migration, dubbed 'swashing.' A separate study reveals a molecular 'gearbox' in flavobacteria that controls directional movement.

Profamilia presented a study on gender-based violence in Medellín, Cali, Uribia, and Dibulla, gathering input from over 8,500 people. The research shows that 58.4% of girls, boys, and adolescents experienced at least one form of violence in the last year. Accompanying the study is the 'Somos Visibles: Generaciones Sin Violencias' initiative to reach over 9,500 people by 2029.

A new study warns of an interdisciplinary blind spot that could force 132 million people to flee rising sea levels, which could rise by up to 150 centimeters. Swedish oceanographer Ola Kalén at SMHI describes the acceleration of sea level rise since the 1960s as shocking.

A new study has revealed over 200 metabolic enzymes attached directly to human DNA inside the cell nucleus, challenging traditional views of cellular processes. These enzymes form unique patterns in different tissues and cancers, described as a 'nuclear metabolic fingerprint.' The discovery suggests links between metabolism and gene regulation that may influence cancer development and treatment.
