A study found that genetic factors influence callous-unemotional traits in boys, while environmental factors are more significant for girls. High levels of CU traits and conduct problems were associated with negative child and family factors.
Canada Research Chair Barbara Sherwood Lollar's research examines the effectiveness of bioremediation technologies in cleaning up groundwater contamination. Her techniques use isotopic signatures to track clean-up progress, providing a critical framework for regulators and practitioners.
Researchers have developed a method to disperse pathogenic fungi as a means of preventing malaria spread, using synthetic oil to increase dispersal effectiveness. The fungi cause muscardine disease in mosquito larvae, killing up to 50% more larvae than untreated spores and reducing pupation levels.
Researchers study island settlements to understand human resilience and capacity for colonization. Mobility, social networks, and knowledge of the local environment helped indigenous people survive in the face of natural disasters and climate change. The findings inform how we adapt to vulnerabilities and rebound from catastrophes.
The Global Human Settlements Layer (GHSL) uses advanced algorithms to automatically analyze medium resolution satellite data, providing fast and precise mapping of built-up areas worldwide. This enables regular monitoring of human settlement changes and improved damage analysis in disaster-stricken areas.
Using amphetamines like Benzedrine and Dexedrine may increase the risk of developing Parkinson's disease, according to a new study. The research, which followed 66,348 participants in northern California, found that those who used these drugs were nearly 60% more likely to develop the condition.
A team of international experts has established a unified approach toward measuring sustainability, identifying valid and reliable indicators to evaluate progress and proposals. The framework aims to promote common language and measurements globally.
Scientists have successfully controlled the electrical conductance of a single molecule by manipulating its mechanical properties. The research uses a type of molecule called pentaphenylene and demonstrates that changing the tilt angle can increase conductance up to 10 times, thanks to lateral coupling effects.
Archaeologist C. Michael Barton is revolutionizing the field of archaeological modeling by integrating new methods with a radical shift in thought. His research suggests that even small communities can experience significant environmental impacts from practices like shifting cultivation and grazing.
Researchers can manipulate the brain's perception of its own body, allowing for new prosthetic limbs and virtual reality experiences. This technology has significant implications for fields like medicine, psychology, and robotics.
Researchers at Washington University School of Medicine have decoded the genome of Trichinella spiralis, a parasite that causes trichinosis, identifying unique features and novel genes that could lead to effective treatments. The study has implications for understanding parasitic diseases worldwide.
The One Health concept aims to integrate surveillance activities across species to monitor and respond to emerging zoonotic diseases. ProMED-mail's global surveillance system has reported over 10,000 animal health issues, highlighting the need for improved interspecies collaboration.
New research reveals the Earth's core is rotating at a rate of approximately 1 degree every million years, much slower than previously estimated. This finding provides insight into the evolution of the Earth's magnetic field and has implications for simulations of the outer core's convection.
The actual population trajectory is highly uncertain, with scenarios predicting a peak of 9.5 billion before stabilization or decline. Investments in family planning could reduce the number of people to 8 billion, having a beneficial impact on human welfare and environmental issues.
The US lags behind other countries in nuclear fuel recycling due to unfounded concerns and myths. Reprocessing spent fuel can recover significant energy value and reduce high-level nuclear waste volume.
New research suggests prevention of unwanted births may be a larger factor in fertility decline in developing countries. Contraception's success has played a significant role, especially in low-income countries, where meeting unmet demand could reduce population growth by 250 million by 2050.
A recent study emphasizes the importance of considering urban dynamics, national policies, and economic globalization when researching tropical deforestation. The researcher argues that current models are too simplistic, ignoring the complex feedback loops between human decisions and environmental changes.
A new blood pressure measurement device using CASP has been developed to provide more accurate readings than current methods. The device, invented by scientists at the University of Leicester and HealthSTATS International, measures pressure close to the heart, leading to better treatment decisions and patient outcomes.
Watersheds are living systems essential for healthy communities, according to Canada Research Chair Margot Parkes. She advocates for an integrated approach to water management that involves communities, governments, and researchers working together.
Swedish scientist Laura Fratiglioni's research shows that active mental, physical, and social activities can preserve cognitive functions and lower the risk of developing dementia. Factors such as blood pressure, weight, and genetics also play a role in determining an individual's risk.
New research shows reovirus-infected cancer cells release pro-inflammatory proteins that recruit and activate white blood cells, killing cancer. A cellular signalling protein, Ras, is abnormally activated in many cancers, providing a window of opportunity for reovirus infection.
The Integrated Assessment of Black Carbon and Tropospheric Ozone identifies emission reduction measures that can immediately protect climate, public health, and ecosystems. Implementing these measures could reduce future global warming by 0.5oC and potentially halve the projected increase in global temperature by 2050.
A new study found that young people with a family history of melanoma are still ignoring sun safety advice, despite being aware of the risks. The research showed that younger women in particular viewed tanning as healthy and were less likely to use sunscreen.
Researchers found that adding an organic molecule layer can increase quantum dot solar cell efficiency three-fold. The layer helps keep electrons apart, preventing recombination and increasing electrical charge production.
A new study by Kate Mulligan examines the connection between cities, water, and health, finding that even in wealthy cities with excellent public services, dengue fever still spreads due to environmental factors. The research suggests that traditional links between poverty and water-related diseases may be overstated.
The UK's failure to address its alcohol problem could result in a significant increase in liver deaths, with the country facing a projected 77,000 excess deaths over 20 years if it doesn't adopt effective policies. The authors argue that increasing alcohol quality and limiting availability of cheap products can help reduce death rates.
