Just in time for the holidays, researchers at the University of California, Irvine and other institutions are rolling out a new satellite-based drought severity index for climate watchers worldwide.
A team of University of Alberta engineers has developed a new way to produce electrical power that can charge handheld devices or sensors that monitor anything from pipelines to medical implants. The discovery sets a new world standard in triboelectric nanogenerators by producing a high-density DC current--a vast improvement over low-quality AC currents produced by other research teams. The devices can transform mechanical energy such as wind or vibrations into electricity.
A two-year study of Rice University property damaged by a 2011 forest fire found that charcoal behaved very differently from other forms of soil carbon as the land rebounded from the fire. The study could help researchers and land managers make better use of charcoal soil amendments called biochar.
New research at the University of Waterloo could lead to the development of batteries that triple the range of electric vehicles.
New paleontological research shows that during the late Permian, the equator was dry and desert-like, yet surprisingly a hotspot for biodiversity. Similarly to modern rainforests, equator ecosystems were home a unique diversity of species, including those both anciently and newly evolved. After the late Permian extinction, this diversity was decimated, and the climate change event that triggered an extinction back then is informative as we move forward with protecting our planet's species diversity.
Air quality experts from the University of Surrey are calling on private businesses to help the Middle East and North African (MENA) region reduce harmful emissions after conducting a comprehensive review on air pollution.
In late December 2014, a submarine volcano in the South Pacific Kingdom of Tonga erupted, sending a violent stream of steam, ash and rock into the air. The ash plumes rose as high as 30,000 feet (9 kilometers) into the sky, diverting flights. When the ash finally settled in January 2015, a newborn island with a 400-foot (120-meter) summit nestled between two older islands -- visible to satellites in space.
Scientists have built a miniature scaffold inside bacteria that can be used to bolster cellular productivity, with implications for the next generation of biofuel production. Because there is a growing need for agricultural or renewable production of biofuels and other commodity chemicals to move away from fossil fuels, scientists have long sought to enhance the internal organisation of bacteria and improve the efficiency of the cells for making nutrients, pharmaceuticals and chemicals.
Around the holidays, a sprig of mistletoe over a doorway is festive and romantic. But mistletoe has a sinister side: The parasitic plant can sometimes kill the very tree it depends on for food by robbing its host of water during dry spells, according to new research being presented here.
Hundreds of marine turtles die every year after becoming entangled in rubbish in the oceans and on beaches, including plastic 'six pack' holders and disgarded fishing gear.
