Researchers at Virginia Tech have discovered that northern cricket frogs use a unique method to move across water by performing rapid belly flops, according to a study in the Journal of Experimental Biology. This method involves the frogs briefly submerging before launching themselves upwards, creating an illusion of walking on water.

Pet dogs can be a significant but overlooked source of salmonella infection in humans, according to a study in Zoonoses and Public Health. Researchers found 87 cases of salmonella in dogs from 2017 to 2023, with most strains also capable of infecting humans and possessing antimicrobial resistance genes.

Researchers have identified the dusty crayfish, Cherax pulverulentus, as a new species native to New Guinea during an analysis of aquarium shipments. Known for its striking purple and blue coloration, this species is now formally classified, shedding light on the biodiversity of New Guinea, according to a study in Zootaxa.

A study in Cognition and Emotion reveals that subtle eye features like pupil size and iris brightness significantly influence perceptions of attractiveness and friendliness. Larger pupils and brighter irises in non-human primates were linked to higher ratings of cuteness and generosity, suggesting these traits affect social impressions.

A study in Physical Review Letters proposes using the Earth's ionosphere to detect dark matter particles such as axions and dark photons. By converting these particles into low-frequency radio waves, the method leverages the ionosphere's well-monitored plasma properties to potentially identify dark matter signals.

A study in the British Journal of Sports Medicine highlights potential benefits of regular exercise before a cancer diagnosis, leading to a significant reduction in cancer progression and mortality. The research, involving more than 28,000 people with stage 1 cancers, found that those with moderate to high activity levels were 27% less likely to show cancer progression and 47% less likely to die from any cause.

A study in Pediatrics shows that 15.4% of US children received at least one vaccine dose outside the recommended age over a 10-year period, with rotavirus vaccines most frequently involved. The study, which analyzed data from the 2011-2020 National Immunization Survey-Child, found that children with multiple health care providers or who moved between states were more likely to receive invalid doses.

Johns Hopkins Kimmel Cancer Center and Howard University Cancer Center have renewed their partnership to address cancer health disparities among underserved populations in the Washington, D.C., area. The Howard-Johns Hopkins Comprehensive Alliance in Cancer Research, Education and Equity will receive $13.5 million over five years from the National Cancer Institute to support initiatives including clinical trial enrollment and training for young investigators from diverse backgrounds.
