The power of touch

A new study by the Smithsonian Tropical Research Institute reveals that tropical slipper limpets alter their sex change in response to physical contact with conspecifics. The larger snail changes to female sooner, while the smaller one delays its sex change.

UAlberta innovation sheds light on how genetic information travels from cell's nucleus

Researchers at UAlberta have developed a new microscope technology that allows them to observe particles in a living yeast cell and track the route of RNA transport from the nucleus to the cytoplasm. This breakthrough finding has significant implications for medical advances and understanding of cellular biology.

New SIR-Network Model helps predict dengue fever epidemic in urban areas

A new mathematical model helps researchers predict the spread of dengue fever in urban areas by analyzing neighborhood conditions and human travel patterns. The SIR-Network model reveals that central neighborhoods are crucial hubs for transmission, emphasizing the need for countermeasures before epidemics peak.

Music therapy increases effectiveness of pulmonary rehabilitation for COPD patients

Patients with COPD who received music therapy in conjunction with standard rehabilitation showed improved symptoms, psychological well-being, and quality of life. Music therapy incorporated breath control techniques, patient-preferred music, and visualizations to increase engagement and cope with chronic disease challenges.

A mathematical model for animal stripes

Researchers assembled various models into a single equation to identify the variables controlling stripe formation. The integrated model predicts three main perturbations that can affect how stripes orient, including changes in production and parameter gradients.

In China, training doctors reduced STI risk

A study published in The Lancet Global Health found that doctors trained on sexually transmitted infections (STIs) had 38% lower odds of patients being infected with gonorrhea or chlamydia. This training also led to improved knowledge among physicians and reduced rates of new STI transmissions.

Educating patients improves knowledge and attitudes about participating in research

A study by Case Western Reserve University School of Medicine found that a tailored video education program improved cancer patients' knowledge and reduced negative attitudes towards clinical trials. The PRE-ACT program was more effective than text-based information in encouraging participants to consider clinical trials.

Marijuana derivative reduces seizures in people with treatment-resistant epilepsy

A new open-label trial of prescription cannabidiol (CBD) shows significant reduction in seizure frequency and well-tolerated for most children and young adults. The study also found a sufficient safety profile with minimal adverse events, but more research is needed to definitively recommend CBD as a treatment.

Cruise passengers spend less despite offers on land

A study by University of Bergen researchers found that cruise tourists spend less during port visits, regardless of shopping opportunities. In contrast, land tourists spend significantly more on Sundays and holydays. The study also revealed that repeat visitors tend to return as either land or cruise tourists, not the other way around.

Towards the rational use of medicines

Researchers assessed the impact of evidence-based principles on medicine procurement in a healthcare facility, achieving significant decreases in expenditures. The ABC/VEN-analysis method helped prioritize medicines and inform training workshops for medical professionals.
