The experienced mindfulness group performed better than others, indicating that practicing mindfulness helps focus and handle stressful situations.
Scientists at the University of Bristol discovered that carbon chains can form helical shapes dependent on their length, with even-numbered chains adopting fusilli-like structures and odd-numbered chains forming floppy spaghetti-like shapes. The researchers controlled the shape by inserting methyl substituents along the chain.

Researchers found Ebola survivors in Liberia had higher rates of uveitis, muscle pain, fatigue, and joint pain compared to a control group. Physical exams also revealed abnormal findings in abdominal, chest, and neurologic areas.
Researchers found that cytosine base editors (BE3 and HF1-BE3) cause unexpected genome-wide off-target mutations in rice, with single-nucleotide variants predominantly occurring in transcribed genic regions. The high frequency of these mutations suggests a need for optimization to increase the specificity of cytosine base editors.

A trial published by The BMJ found that employees who used sit-stand workstations reduced their sitting time by more than an hour a day over 12 months, with improvements in job performance, psychological health, and daily anxiety. The results suggest that displacing sitting with standing may have positive effects on work-related outcomes.
Women who drank an additional 1.5 liters of water daily experienced 48% fewer repeat bladder infections than those who drank their usual volume of fluids, according to the study. This finding is significant as over half of women report having bladder infections, which are one of the most common infections in women.
Testosterone treatment over 10 years can improve or reverse type 2 diabetes in men with low testosterone, leading to significant weight loss. The study found that average fasting blood glucose levels decreased and HbA1c levels fell in the testosterone-treated group, while worsening in the control group.
