A University of Calgary-led study has found evidence that children with genes predisposing to migraine might have an increased risk of having more headaches after a concussion, which are known to be linked to prolonged symptoms up to six-months after the injury. Researchers looked at over 600 children aged 8 to 16 who presented with symptoms of concussion, and followed them for six months post injury. It is the first study that has looked at specific genetic factors for migraine and post-concussion outcomes.

Adolescents who consume more ultra-processed foods (UPFs) have significantly higher odds of being overweight or obese, according to a new systematic review and meta-analysis published in the open-access journal PLOS One by Mekuriaw Nibret Aweke of the University of Gondar, Ethiopia, and colleagues. In the most recent of the analyzed studies, higher UPF consumption was linked with more than twice the odds of overweight or obesity compared to lower UPF consumption.

Salk scientists find naked mole rat colonies are capable of peaceful queen succession, illuminating a new layer of social complexity for naked mole rats, which are important models in biomedical research on socialization, aging, adaptation, fertility, and more. The findings also help answer broader questions about biological resilience, potentially revealing principles that can explain human health and disease.

New research shows that dialing down an overactive immune sensor can restore tissue health in severe genetic disorders, reshaping how scientists think about aging and DNA damage.
