Researchers argue this oversight undermines effective teaching and call for rethinking curriculum design to integrate hands-on, body-centered learning approaches that could improve student outcomes and retention.EN

Researchers have identified a gel coating that protects intervertebral discs from immune system damage following microdiscectomy, the most common back surgery. The synthetic mucin-based approach could reduce the need for repeat surgeries and extend the lifespan of surgical outcomes—a significant economic opportunity in the $15 billion spine care market.EN

Doctors in Scotland and Sweden frequently misclassified heart attacks when applying international diagnostic standards, a new study reveals. The findings highlight gaps between clinical guidelines and practice—a problem that could affect treatment decisions, patient outcomes, and how hospitals benchmark their care quality.EN

Swedish researchers found that when university students' family members or roommates caught COVID-19, the students themselves suffered measurable declines in mental health and academic confidence—even without getting sick themselves. The finding suggests that institutional policies around housing, isolation, and mental health support need to account for indirect contagion effects on vulnerable populations.EN

Melting permafrost, industrial pollution, and climate change are converging in the Arctic to accelerate the spread of animal-to-human diseases—a threat with major implications for public health infrastructure and resource sectors operating in remote northern regions. Researchers warn that limited surveillance and healthcare access in these areas could amplify the health and economic costs of emerging zoonotic outbreaks.EN

A large new study reveals women report significantly greater job satisfaction from meaningful work than men—yet this apparent advantage conceals persistent gender inequality. Women cluster in lower-paid caring professions that offer purpose but not power, suggesting the gender wage gap persists partly because women accept less lucrative roles in exchange for work they find morally rewarding.EN

Mobocertinib, the first drug designed specifically for a hard-to-treat lung cancer mutation, helped only one-third of patients in a real-world study while causing severe side effects in 38% of cases. Women were seven times more likely to stop treatment than men, raising questions about whether the drug's modest benefits justify its risks for broader patient populations.EN
