Geologists from Wits University in Johannesburg, South Africa, have come up with an original explanation of how nature may produce an intriguing class of magmatic rocks that are made up of only one type of mineral.
In coastal communities prone to hurricanes and tropical storms, people typically turn to engineered solutions for protection: levees, sea walls and the like. But a natural buffer in the form of wetlands may be the more cost-effective solution, according to research from the University of California San Diego. The study is the most comprehensive of its sort to date.
Concern regarding impacts of pesticides on the environment and human health has led to the development of integrated pest management (IPM) programs. A component of these programs involves the use of observation of pest populations in the field to direct timing of pesticide applications. Central to the concept of IPM is the use of an economic threshold of a population level where an application of a pesticide is advisable.
Researchers at the Leibniz-Institute for Food Systems Biology at the Technical University of Munich (Leibniz-LSB@TUM) have confirmed the presence of the rare amino acid ethionine in a plant -- or more precisely, in the fruit of the durian tree. Despite its pungent odor, durian is very popular in Southeast Asia. As the team of scientists has shown, the amino acid plays a key role in the formation of the characteristic durian odor.
A new MSU study is the first to precisely quantify soil and landscape features and spatial and temporal yield variations in response to climate variability.
Researchers at Wits University in Johannesburg, South Africa, have created the world's first framework, to better guide the management of terrestrial invasive species.
Plants obtain their energy from the sun. Other beings rely on eating to survive. Yet how does the energy flow inside ecosystems function and are there differences between ecosystems with many species in comparison to those with few species? Researchers have now examined these questions using a holistic approach by evaluating data gathered through a large-scale biodiversity experiment.
Otago scientists studying sperm whales off the coast of Kaik?ura have discovered earthquakes affect their ability to find food for at least a year. The University of Otago-led research is the first to examine the impact of a large earthquake on a population of marine mammals, and offers new insight into how top predators such as sperm whales react and adapt to a large-scale natural disturbance.
How can we anticipate and design out environmental impacts of new technologies when they are at an early stage of development? A new issue of Yale's Journal of Industrial Ecology presents cutting-edge research on the environmental assessment of emerging technologies.
A simple, portable test that can detect the deadliest of the mushroom poisons in minutes has been developed by Agricultural Research Service (ARS) scientists. Eating toxic mushrooms causes more than 100 deaths a year, globally, and leaves thousands of people in need of urgent medical assistance. Amanitin is the class of mushroom toxins that cause the most serious issues.
