Discovery points to new approach to fight dengue virus

Researchers have discovered that rising temperature induces key changes in the dengue virus when it enters its human host, leading to a new approach for designing vaccines against the aggressive mosquito-borne pathogen. The study found that the virus's bumpy form is more efficient at infecting mammalian cells.

Research examines effects of opioids on patients with sickle cell disease

Researchers found diverse consequences of opioid use in patients with sickle cell disease, including biological, psychological, social, and spiritual effects. The study used a grounded theory approach to gather data from 21 African-American adults with SCD, revealing divergent effects on relationships, productivity, mood, and outlook.

Individual donation amounts drop when givers are in groups

Researchers found that even with multiple individuals contributing to a common cause, group presence reduces an individual's willingness to help. Fundraising strategies can be influenced by social factors, such as emphasizing personal donations and avoiding group interactions.
