Medical personnel working in conflicts must recognize and document sexual violence, provide necessary care, and advocate for justice to prevent ...
The environment plays a significant role in cancer development, with occupational factors and environmental pollution attributed to 5-7% of cancer deaths. Dr. Richard Clapp reviews the relationship between environmental exposure and cancer, emphasizing the importance of cancer prevention and physician screening for hazardous exposures.
Researchers have identified regulatory cells that govern the behavior of stem cells in Drosophila, revealing a specialized cellular environment known as a niche. The niche environment provides support needed for stem cell self-renewal, and its characteristics may offer insights into human stem cell regulation.
The International Conference on Heavy Metals in the Environment will discuss successes and failures of research on human exposure to toxic metals. Major themes include risk assessment, environmental epidemiology, and human health effects, with a focus on protecting children from toxic metals.
A new IIASA report examines Namibia's population growth, environment, and development, providing a comprehensive understanding of the country's challenges and opportunities. The study highlights the importance of sustainable human development and explores alternative policy scenarios for Namibia's future.
Volunteers use virtual reality helmet and computer program to take actions like turning on TV or stereo by simply wishing it so, in breakthrough study that may someday enable patients with extreme paralysis to regain control of their surroundings
Researchers from around the world present real-world and theoretical findings on valuing environmental services, exploring challenges of assigning economic values to ecosystems and regulating the environment. The study highlights the complexities of managing ecosystem resources and incorporating costs of pollution into prices.
Researchers at UCSF found that reducing a worm's ability to perceive its environment through smell or taste extends its lifespan by more than a third, from two weeks to three or four weeks. This suggests that chemical signals from the environment, possibly pheromones or food smells, influence aging in C. elegans.
A new Cornell University study suggests that without democratic population-control practices and resource-management policies, the world's 2 billion people will face a difficult life by 2100. The report predicts an optimal population of 2 billion, with a standard of living about half that of the United States in the 1990s.
