Researchers map genome for cats, dolphins, birds, and dozens of other animals

Scientists mapped genetic blueprints for 51 vertebrate species, including cats, dolphins, and birds, using novel algorithms and computer software. This discovery has huge implications for understanding human health and evolution, as it allows researchers to compare complete genomes and identify DNA sequence divergence.

First-ever sighting of a live newborn great white

Wildlife filmmaker Carlos Gauna and UC Riverside student Phillip Sternes observed a 5-foot-long pure-white shark pup shedding its embryonic layer. The location off central California's coast is proposed as a potential great white breeding ground, which could help protect endangered species.

Racial and ethnic differences in hypertension-related telehealth

A new study found that Hispanic adults had the highest proportion of hypertension-related telehealth visits, while those with lower levels of hypertension awareness and treatment received more in-person visits. Telehealth use increased among Medicaid recipients regardless of race or ethnicity during the pandemic.

Food insecurity and premature mortality and life expectancy in the us

A study of 57,000 US adults found that lower levels of food security are associated with a higher risk of premature mortality and shorter life expectancy. The findings highlight the potential importance of improving food security in promoting population health and reducing health disparities.

Alzheimer’s disease acquired from historic medical treatments

Researchers have identified five cases of Alzheimer's disease acquired through exposure to contaminated cadaver-derived human growth hormone (c-hGH) used in medical treatment between 1959 and 1985. Biomarker analyses and autopsy results confirmed the diagnoses, highlighting a rare but significant risk of transmission via this route.
