Emergency room or doctor's office?

A new study found that African American men are more likely to visit a doctor's office or clinic for healthcare due to higher threat sensitivity and having insurance. In contrast, those with lower threat sensitivity and no usual place for healthcare were more likely to frequent the emergency room.

Cancer-fighting combination targets glioblastoma

Researchers paired a calorie-restricted ketogenic diet with a tumor-inhibiting antibiotic to destroy cancer stem cells and mesenchymal cells in glioblastoma, a fast-moving brain cancer. The combination killed tumor cells while reversing disease symptoms and improving mouse survival.

Research confirms gut-brain connection in autism

A recent study has confirmed a link between gut problems and autism, revealing that the same gene mutations in the brain can also affect the gut nervous system. The discovery suggests that gastrointestinal issues may stem from the same mutations responsible for brain and behavioral issues in autism.

New framework helps gauge impact of mosquito control programs

A new statistical framework has been developed to evaluate the effectiveness of mosquito control programs across various time and space scales. The model, applied to a citywide intervention in Iquitos, Peru, found that insecticide spraying reduced Ae. aegypti populations by an average of 67%.

COMMD3/8 protein complex: a potential drug target for treating inflammatory diseases

Researchers discovered a molecule involved in immune cell migration that plays a critical role in establishing immune responses. The COMMD3/8 complex promotes signal transduction of chemokine receptors to facilitate immune cell migration, which is essential for efficient immune responses and proper functioning of the immune system.

Teens at greater risk of violence, injury during sexual assaults than previously thought

A recent study of 563 sexual assault cases in Massachusetts found striking similarities in the types of injuries and violence experienced by adult and adolescent victims. Teenage victims were more likely to experience violence, force, and choking, with significant increases in use of force as age increased.

A new mechanism for accessing damaged DNA

Researchers from the Thomä group at FMI have identified a new mechanism by which UV-DDB detects and binds to damaged DNA tightly packed in nucleosomes. This mechanism, known as 'slide-assisted site-exposure', allows repair proteins to bind to lesions without requiring additional proteins or chemical energy.

Clean air taxis cut pollution in New York City: Study

A new study by Columbia University researchers found that the city's Clean Air Taxi regulations led to significant reductions in air pollution emissions, with overall fuel efficiency of medallion taxis doubling between 2009 and 2015. The emission reductions were associated with decreases in concentrations of pollutants in the city's air.
