A UK patient database analysis found tramadol increases hip fracture risk by up to 1.5 new cases per 1000 person-years, compared to other pain medications. The study highlights the need for tramadol's fracture risk to be considered in clinical practice and treatment guidelines.
A new study found that Raise Your Resilience program, focusing on gratitude and positive attitude toward aging, increased resilience and wisdom among seniors. The program, delivered by non-licensed staff, reduced daily stress and improved overall well-being in senior housing communities.
Researchers found that ocean surface temperatures were more important than solar radiation in driving rainfall in the region. This discovery provides context for the development of tropical rainforest ecosystems in Central America and sheds light on the impacts of climate change on ancient civilizations.
Astronomers will use transmission spectroscopy and phase curves to observe the atmospheres of seven rocky planets in the TRAPPIST-1 system. The goal is to determine if these planets have atmospheres and what they're made of, which could help find out if life as we know it could survive on these distant worlds.
Researchers charted immune system development in sub-Saharan African children to improve vaccine efficacy. Their findings suggest that a child's age, location, and health status influence their immune response to vaccines.
A large dataset of daily resting heart rates from wearables reveals significant individual variations, accounting for less than 10% of variation between people. The analysis also identifies seasonal trends and brief periods of abnormal heart rate.
Researchers used new technology to analyze the self-assembling gateway structure within lithium-ion batteries, revealing its composition and chemical make-up. The study aims to create more energetic, longer-lasting, and safer batteries.
A recent study cataloged genetic fingerprints of DNA-damaging processes driving cancer development, providing clues on how each cancer developed. The research will help understand cancer causes, inform prevention strategies, and signpost new directions for diagnosis and treatments.
Researchers have completed the most comprehensive study of whole cancer genomes to date, revealing key mutations driving cancer growth. The atlas provides a solid foundation for understanding which genes are damaged in each cancer type.
A study of 677 participants found higher abdominal fat was associated with lower scores on memory and language tasks. Visceral adiposity may impact cognitive decline in older patients with diabetes, emphasizing the importance of targeted interventions.
