A recent study found that undocumented foreign-born Latinos have lower levels of usual source of care, blood pressure checks, and cholesterol screenings compared to US-born Latinos. Perceived quality of care is also significantly impacted by immigration status.
A recent study published in PLoS ONE found that French brown bears are at risk of extinction due to a lack of females. The researchers suggest that relocating new bears could not only boost the population size but also reverse some of the causes of the decline by introducing more females.
A new study reveals a 71% increase in Down syndrome pregnancies and births over 20 years, largely due to women delaying childbearing. Despite this rise, improvements in prenatal screening have maintained the number of babies born with the condition at around 750 per year.
The FASTSAT mission will analyze the Earth's outer atmosphere with three NASA-built instruments: Thermosphere Temperature Imager (TTI), Mini-ME neutral atom imager, and Plasma and Impedence Spectrum Analyzer (PISA). The instruments will provide critical data for global space weather prediction, improving communication and navigation.

The researchers found significant gaps in care for these conditions, with the uninsured being more likely to experience poor blood pressure control and inadequate treatment.
A study by Professor Diego Becerril Ruiz found that 79% of Spanish people think divorce is the best solution when a couple can't solve marital problems. The country ranks second in social acceptation of divorce, after Brazil, and shows an increase in divorce acceptance since the 1990s.
A study published in JAMA found that attending physicians working nighttime hours did not have a significantly increased rate of complications for procedures performed the next day. However, having less than six hours of sleep opportunity between procedures was associated with an increased rate of surgical complications.
The San Diego Supercomputer Center (SDSC) is part of a four-year project called 'FutureGrid' that aims to develop and test new approaches to parallel, grid, and cloud computing. Researchers will collaborate to create an experimental high-performance grid test-bed, enabling the detection of bugs in software before production.
A study by Pascale Quester and Alexandre Steyer found that consumers seek variety initially, then conform to group norms, before re-embracing individuality when a choice becomes dominant. In a restaurant setting, this pattern was observed with customers opting for alternative drinks when others chose the same option.
A recent study published in Archives of Surgery found that individuals with ethanol in their bloodstreams are less likely to die following a moderate to severe head injury. The study analyzed data from 38,019 patients and found a significant decrease in mortality rates among those with alcohol in their bloodstreams.
Researchers found that zero tolerance laws had no effect on the number of nighttime accidents involving drivers under 21. Instead, other factors such as heavy drinking and mild drinking were consistent across all accident types.
A new study finds that chronic job insecurity has a stronger negative impact on worker health than smoking or hypertension. Persistent job insecurity weakens bonds between employers and employees, fueling perceptions of insecurity.

The study used geodesy to measure rock movements and revealed that the fault is actively slipping at a rate of approximately one-tenth of an inch per year.
Hip fracture rates declined by 31.8% in females and 25% in males between 1985 and 2005, with the largest decrease among individuals aged 55-64 years. The reasons for this decline are unclear, but factors such as overweight and obesity may contribute.
A study by Purdue University researchers found that individuals with high neuroticism levels are more likely to engage in unhealthy behaviors such as smoking and heavy drinking. These behaviors can contribute to an increased risk of mortality, making it essential to develop targeted interventions for this population.
A recent study emphasizes the importance of evaluating eHealth interventions to improve the quality and safety of healthcare.
