This mechanism may help scientists develop strategies to control bacterial growth, either beneficially in bioreactors or pathogenically on medical devices.
A recent study by researchers at the University of Toronto found that immigrant parents and refugees are more likely to experience mental health issues and socioeconomic challenges. Their children are also more likely to fall behind in learning before kindergarten, which can have long-term implications for their education and development.
A study by University of Illinois ornithologist Mike Ward found that 85% of Canada geese wintered in the Greater Chicago Metropolitan Area, with none making foraging flights to agricultural fields. The birds' ability to minimize risk by using urban areas suggests they are prioritizing survival over energy intake.
A new Berkeley Lab study finds that cool roofs can save up to 9% of outdoor water consumption in California counties. Widespread adoption could result in 83 million gallons of water savings daily in Los Angeles County.
A study of African-American and Latino adults in a high-risk urban community found that despite numerous risk factors, the rate of substance use problems is low for a substantial proportion of participants. Protective 'resilience' factors, such as support, education, and employment, also play a crucial role in preventing substance misuse.
Researchers found that users struggle to use drone images to locate objects on the ground, posing challenges for emergency operations and applications. Switching from an aerial view to a ground view slows down estimates of object location, with incorrect placements four times farther away.
Suburban areas in the US face barriers to healthcare access, including limited community health centers and free clinics. Poor suburbanites have higher odds of being uninsured and having unmet healthcare needs compared to higher-income adults.
A new study published in Academic Emergency Medicine found no association between prehospital advanced cardiac life support and survival for patients with out-of-hospital cardiac arrest. Instead, the study suggests focusing on increasing bystander CPR, decreasing response times, and defibrillation.
A study found that 40% of cancer patients at an urban cancer center were diagnosed with depression, with three-fourths of these cases being previously undiagnosed. Female patients and disabled patients were more likely to be depressed, emphasizing the need for mental health screening and care.
Researchers found utilizing local artists' images and dialects helped address misperceptions about Ebola treatment, involving trusted messengers for two-way communication. The study's evidence-based approach can inform message development and implementation during public health emergencies.

The study showed significant benefits from incorporating physical activity into daily life, regardless of intensity.
Research highlights the disparity in firearm injury rates among pediatric populations in urban and rural settings. Teenagers living in urban areas are disproportionately affected by firearm assaults, whereas children in rural areas face a higher risk of accidental firearm injuries. Accidental injuries were the leading cause of hospital...
A study of nine young athletes found that contact drills involving multiple players led to the highest number of head impacts, while open-field tackling resulted in high-magnitude impacts. The study suggests modifying or eliminating certain drills from practice sessions to reduce injury risks.
Researchers found that racially segregated areas had higher mortality rates in both urban and rural areas, but blacks sometimes lived longer in segregated areas. This may be due to less exposure to deadly infectious diseases before antibiotics were widely available.
A large-scale study of 135,335 individuals across 18 countries found that a moderate intake of fruit, vegetables, and legumes can significantly reduce the risk of cardiovascular disease and death. The study's findings indicate that consuming an average of 3-4 servings per day is as beneficial as higher amounts in reducing total mortality.
A new study from Brown University found that less than one-third of teachers perceived as ineffective by principals are actually formally rated that way. Despite major reforms, time constraints and top-down system designs limit the differentiation and support for teacher effectiveness.
A recent study finds that megacities generate an average of $505 million in ecosystem services from trees, including air and water filtration, stormwater management, and energy savings. The value of tree benefits could be doubled by increasing tree cover, improving urban well-being and mitigating climate change.
Suicide rates in rural areas of Maryland are 35% higher than urban settings, driven by significantly greater use of firearms. Removing firearms from the equation reveals comparable suicide rates between rural and urban areas.
