Teens who lose teeth to decay and injury nearly twice as likely to be bullied, study reveals

A study of over 4,400 Australian children found that those experiencing tooth loss were more than four times as likely to be bullied. Children from lower socioeconomic backgrounds and rural areas were disproportionately affected. The researchers highlight the need for improved access to dental care and prevention programs.

Well-being and ill-being do not lie on a single continuum

A large-scale UK study supports contextual models of mental health emphasizing values-guided behavior and psychosocial resources for older adults. The study suggests that well-being is not solely the absence of ill-being, but rather a complex interplay between meaning-oriented behavior, psychological flexibility, and stress regulation.

Researchers describe for the first time brain signals associated with forgetting unpleasant memories in humans

The study used Representational Similarity Analysis (RSA) to investigate the neural representations involved in forming and extinguishing associative memories. Researchers found an increase in theta activity in the amygdala when unpleasant stimuli were presented during extinction learning, suggesting a safety signal.

Scientists identify personality traits that help schoolchildren succeed academically

A new study found that children's personality traits such as conscientiousness and open-mindedness have a significant impact on their academic performance. The research, conducted across seven countries, showed that these traits can help reduce educational inequality and improve social mobility.

Oral health treatment in patients due for surgery is associated with significantly lower rates of postoperative pneumonia and shorter hospital stays, per observational study in one Japanese hospital, suggesting it might reduce infection risk

A single-center observational study found that planned preoperative oral care at least 2 weeks prior to surgery significantly reduced rates of postoperative pneumonia and shortened hospital stays. The results suggest that oral health treatment could be an effective strategy for reducing infection risk in surgical patients.

Paleontologists go back to the future, reconstruct fossilized functional diversity to inform conservation goals

Researchers have developed a method to reconstruct functional diversity of past ecosystems from fossils, enabling conservationists to compare healthy ecosystems with modern counterparts that have been altered by humans. This information can be used to set restoration and protection goals for endangered species.

Genes linked to sudden cardiac death increase the risk of heart failure in patients with genetic dilated cardiomyopathy

Patients with genetic dilated cardiomyopathy who experience severe arrhythmias are at an elevated risk of developing advanced heart failure and requiring a heart transplant. Genetic mutations in genes associated with severe arrhythmias and sudden cardiac death increase the risk of serious heart failure complications.
