Racism linked to depression and anxiety in youth

A review of 461 cases found strong associations between racism and detrimental health outcomes such as low self-esteem, reduced resilience, and behaviour problems in children and youth. The study identified an important issue that needs to be addressed in society, schools, and communities to improve child and youth health.

Wetlands more cost-effective in nutrient removal, but multiple payments would be of uncertain value

Researchers found that installing a few wetlands was more cost-effective than upgrading wastewater treatment plants to remove nitrogen pollution. However, the benefits of offering multiple payments for environmental services from wetlands are unclear, and their impact on market outcomes is still debated. The study's findings suggest th...

First-time measurements in Greenland snowpack show a drop in atmospheric co since 1950s

A recent study published in Atmospheric Chemistry and Physics found that atmospheric carbon monoxide levels have been declining in Greenland since the 1970s, despite a global increase in vehicle emissions. The research suggests improvements in combustion technology, such as catalytic converters, may have driven this decline.

Pancreatic stem cells isolated from mice

Researchers have developed a method to isolate and grow pancreatic stem cells from mice, which can differentiate into hormone-producing beta cells or pancreatic duct cells. This breakthrough could lead to the development of new therapeutic interventions for pancreatic diseases like diabetes.

Doing research in the pub

Researchers analyzed customer behavior in pubs and clubs to determine effective signals for ordering a drink. They found that positioning themselves directly at the bar counter is a successful signal, while avoiding these behaviors indicates non-ordering intentions.

TV drug ads: The whole truth?

Researchers found that six out of ten claims made by TV drug ads are potentially misleading, leaving out important information or exaggerating benefits. The study analyzed advertisements for prescription and over-the-counter drugs aired between 2008 and 2010 and found that most claims were either false or misleading.

Automated telephone calls improve blood pressure control

A Kaiser Permanente study found that automated telephone calls increased controlled hypertension among patients, especially those with multiple chronic conditions. The program also showed benefits for female patients with higher incomes and improved health outcomes for both patients and healthcare systems.

'Vicious cycle' shields, spreads cancer cells

Cancer cells exploit a vicious cycle of mucus production to protect themselves from the immune system and promote tumor growth. Researchers at Rice University have identified a potential therapeutic target in rosiglitazone, a diabetes medication that can attenuate this cycle.

JCI early table of contents for Sept. 16, 2013

Researchers have identified a metabolite as a biomarker of diabetes risk, revealing that individuals with increased levels are more likely to develop type 2 diabetes. Additionally, the study found that a specific genetic mutation affects muscle performance in elite endurance athletes by altering calcineurin signaling.

New world map for overcoming climate change

Scientists have created a vulnerability map to help governments and organizations invest in protected area establishment and restoration efforts in the most vulnerable regions. The map assesses ecosystems' intactness and stability under future climate change predictions, identifying southern Asia, Europe, and Australia as high-risk areas.
