The challenges facing our aging nuclear fleet are numerous. Cheap natural gas and the rapid growth of low-cost renewables like wind and solar, which have helped drive electricity prices downward for the first time in decades, make it hard for nuclear power plants to operate profitably. At the ...
The cell is the basic unit of life. Organisms can consist of one cell, known as unicellular organisms, or many cells. There are two basic classifications of cells: prokaryotes, which mostly consist of bacteria, and eukaryotes, which are more advanced. Within the two basic classes, five kingdo...
At the same time it is well known that the aqueous solutions of fluorosurfactants do not wet such commonly used hydrophobic surfaces as polyethylene and polypropylene, although those surfaces are completely wetted by solutions of hydrocarbon trisiloxane surfactants having higher surface tension [17]. T...
When autonomous cars go commercial, the lidars on board are likely to be that size or smaller. Before then, Velodyne and its competitors are aiming to sell lidars into the current car market, for semi-autonomous carsthat provide automatic lane changing and other driver assistance vehicles today....
of species diversity patterns across animals. Given the unprecedented extinction rates that the Earth's biota are currently experiencing, these findings are also quite sobering. We are rapidly losing what it has taken nature hundreds of millions of years to construct, and only time can repair it....
thinning to reduce fire risk is critical to ensure the persistence of wildlife species associated with these forests. But this research suggests suggestforestresilience treatments are not needed to protect Great Gray Owls, and conservation efforts might be better directed to other needs of the species...
