Self-affirmation improves problem-solving under stress

Research published in PLOS ONE found that self-affirmation exercises can improve problem-solving skills and reduce acute stress. Students who performed a self-affirmation exercise scored higher on a subsequent problem-solving task than those who did not, suggesting that self-affirmation may be a useful buffer against chronic stress.

Shaking things up: NIST researchers propose new old way to purify carbon nanotubes

A team at NIST has developed a simple and cost-effective way to separate metallic from semiconducting carbon nanotubes, paving the way for high-purity samples in electronics applications. The method uses liquid extraction with subtle differences in polymer hydrophobicity, yielding high-resolution results.

Expanding Medicaid -- mental and financial health improve, but no improvement shown in physical health

A new study from the Oregon Health Insurance Experiment shows Medicaid coverage substantially reduced depression and eliminated catastrophic medical expenditures, increasing diabetes diagnosis and medication use among low-income adults. However, it had no detectable effect on physical health outcomes such as hypertension, high choleste...

Fossil of great ape sheds light on evolution

A University of Missouri expert analyzed the pelvis fragments of an early hominid fossil, revealing insights into the evolution of modern great apes. The study suggests that the ape's wider pelvis indicates greater lateral balance and stability, while its distinct finger bones indicate a different evolutionary path than initially thought.

Global networks must be redesigned

Helbing's research reveals that global networks can amplify vulnerability to disasters, making it difficult to predict and control complex systems. By redesigning these networks with real-time data, we can enhance transparency, adaptive control, and mitigate catastrophic failures.

Team finds substances in honey that increase honey bee detox gene expression

A new study found that certain compounds in honey, including p-coumaric acid and propolis, can stimulate the expression of detoxification genes and immunity genes in honey bees. This suggests that a diet rich in these substances may help protect against pesticide exposure and other threats.

BUSM study shows positive impact of mind-body course on well-being of medical students

A Boston University School of Medicine study found that a mind-body class elective increased self-regulation and self-compassion among medical students, while decreasing perceived stress. The course, which combined mindfulness meditation and yoga, helped students better manage stress and feel more empowered to connect with patients.

Genomics to reshape endometrial cancer treatment

A new study found that adding genomics-based testing to the standard diagnostic workup could lead to a change in recommended treatment for some women. The research identified four novel genomic-based subtypes of endometrial cancer, which suggest that genetic changes can help guide treatment decisions.

Study: Amusement rides injure 4,400+ kids a year

A study by Nationwide Children's Hospital found that 92,885 children under 18 were treated for amusement ride-related injuries from 1990 to 2010. The most common injury types were soft tissue injuries and head/neck region injuries, with nearly one-third occurring on fixed-site rides.
