A new study suggests reefs suffering coral bleaching can still be productive, as fish dependent on reefs get a bulk of their food delivered via the currents flowing past.
Extracts from the seeds of the Ginkgo biloba tree show antibacterial activity on pathogens that can cause skin infections such as acne, psoriasis, dermatitis and eczema.
Researchers from Sweden and Finland have developed the interactive web-based Maladaptation Game, which can be used to better understand how Nordic farmers make decisions regarding environmental changes and how they negotiate the negative impacts of potentially damaging decisions.
Farmers rely on phosphorus fertilizers to enrich the soil and ensure bountiful harvests, but the world's recoverable reserves of phosphate rocks, from which such fertilizers are produced, are finite and unevenly distributed. Stevens Institute of Technology is spearheading an international effort to map the global flow of phosphorus, much of which will be absorbed by crops, then eaten and excreted as waste by animals and people -- and jump-start efforts to recapture and recycle the vital nutrient.
Princeton University researchers report that the distribution of forest types worldwide is based on the relationships plant species forged with soil microbes to enhance their uptake of nutrients. These symbioses could help scientists understand how ecosystems may shift as climate change alters the interplay between plants, microbes and soil.
Understanding the ecology and distributions of species in Amazonia is hampered by lack of information about environmental conditions, such as soils. Plant occurrence data are typically more abundant than soil samples in poorly known areas, and researchers from Finland and Brazil have now developed a method that uses both plant and soil data to produce a map of soil properties.
Cannabidiol (CBD), a non-psychoactive compound in cannabis, is being touted as beneficial for many health conditions, ranging from anxiety to epilepsy. Although much more research is needed to verify these claims, scientists have now shown that CBD could have a different use as a 'Trojan horse': helping slip medications across the blood-brain barrier (BBB) and into mouse brains. The researchers report their results in the ACS journal Molecular Pharmaceutics.
Research by a team of the world's leading oceanographers has proposed a new explanation for how the ocean absorbs and stores carbon, solving a riddle that has long puzzled scientists. It's well established that carbon in the atmosphere is absorbed by phytoplankton and transported to the ocean floor as the microscopic organisms die and sink by gravity through the water.
A new study into one of the world's oldest types of fish, coelacanth, provides fresh insights into the development of the skull and brain of vertebrates and the evolution of lobe-finned fishes and land animals, as published in Nature.
New research reveals how soil bacteria build the only known enzyme for the destruction of the potent global warming and ozone-depleting gas nitrous oxide. Alongside carbon dioxide (CO2) and methane, the greenhouse gas nitrous oxide (N2O), commonly known as 'laughing gas', is now a cause for great concern, and there is much international focus on reducing emissions. It is hoped that the findings will help pave the way for strategies to mitigate the damaging effects of N2O.
