Patients with a history of depression often deny or attribute early warning signs, such as fatigue and stress, to external factors. Early intervention is crucial to prevent or minimize relapse, and recognizing these signs can provide control over emerging depressions.
New RFF issues brief examines interactions between climate change policies and the tax system. Research suggests that reducing carbon emissions may produce economic benefits when revenues from pollution control are used to reduce other taxes, potentially offsetting added costs. However, policy approaches can significantly impact costs.
A newly isolated bacterium, coccoid Strain 195, reduces toxic tetrachloroethene and trichloroethene to nontoxic ethene gas. The Cornell researchers' discovery will lead to better pollution cleanup strategies in the field.
A recent study found that treating depression in diabetic patients can lead to improved blood glucose control. Researchers discovered that as depression improved, glucose levels also decreased. The study showed that nearly 60% of depressed patients experienced significant improvement after treatment.
A collaborative study between the US and Russia aims to uncover the causes of Hepatitis C, a prevalent liver disease. The project will collect blood samples and questionnaires from over 4,000 individuals across New Mexico and Chelyabinsk-70, with results expected to shed new light on the virus.
A new study of over 1,000 prostate cancer patients found that those who underwent surgery had remarkably good outcomes, with few reporting dissatisfaction or problems with urinary or sexual function. Despite fears about complications, most men felt healthier and satisfied with their treatment after surgery.
Environmental scientists have developed an internet-based chat room to analyze ozone levels, enabling policymakers to make informed decisions. The site provides real-time data and interactive tools, helping researchers better understand the regional nature of ozone transport.
Researchers at UC Davis discovered that plants with simulated leaf domatia attract beneficial insects, reducing spider mite populations and increasing cotton yield by 30%. This mutually beneficial relationship offers a natural biological control strategy to pesticides.
New Arecibo radar images show no signs of ice in permanently shadowed areas at the moon's poles. Researchers believe rough surfaces from impact craters may be responsible for observed reflections instead.
Researchers have developed a technique using liposomes that can detect metal ions in solution, leading to practical sensors for heavy metals, viruses, and environmental cleanup. The technique involves entrapping liposomes in sol-gels, which increases their sensitivity, making them suitable for use in various applications.
A new RFF issues brief highlights the potential impacts of climate change on water supplies, including increased precipitation, evapotranspiration, and extreme weather events. The report emphasizes the need for more efficient water management and use to mitigate these effects.
A recent study published in Science found that genetic inheritance patterns continue to play a significant role in how people learn and process knowledge in old age. The research, conducted on Swedish twins aged 80+, showed that heritability accounted for 55% of individual differences in cognitive ability.
