Study links parathyroid hormone to reduced chronic low back pain in mice by limiting abnormal nerve growth

24. marts 2026 Rapporteret af AI Billede genereret af AI Faktatjekket

A study published in the journal *Bone Research* reports that parathyroid hormone (PTH) reduced pain-related behaviors in mouse models of spinal degeneration, apparently by strengthening vertebral endplates and triggering bone-cell signals that repel pain-sensing nerve fibers. The work was led by Dr. Janet L. Crane of Johns Hopkins University School of Medicine.

Honey bees refine waggle dance based on audience size

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.

Intestinal cells signal brain to curb hunger during parasitic infections

25. marts 2026 Rapporteret af AI

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.

Researchers uncover new bacterial movement mechanisms without flagella

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 launches gender-based violence study

12. marts 2026 Rapporteret af AI

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.

Blind plet kunne tvinge 132 millioner til at flygte fra stigende havniveauer

Et nyt studie advarer om en tværfaglig blind plet, der kunne tvinge 132 millioner mennesker til at flygte fra stigende havniveauer, som kunne stige med op til 150 centimeter. Den svenske oceanograf Ola Kalén ved SMHI beskriver accelerationen af havniveauets stigning siden 1960'erne som chokerende.

Researchers uncover metabolic enzymes on human DNA in cell nucleus

9. marts 2026 Rapporteret af AI

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.
