The accelerated expansion of the present universe, believed to be driven by a mysterious dark energy, is one of the greatest puzzles in our understanding of the cosmos. The standard model of cosmology called Lambda-CDM, explains this expansion as a cosmological constant in Einstein’s field equations. However, the cosmological constant itself lacks a complete theoretical…

For years, various models have been developed to describe an important class of mixing effects that occur, for example, in the flow in a chemical reactor. Experimental validation, however, has lagged far behind due to the superimposition of gravity effects. For years, various models have been developed to describe an important class of mixing effects that…
New research from the University of the Sunshine Coast has found a decline in the number, size and diversity of Queensland’s apex sharks, marking a “significant shift” in our coastal ecosystems.

Winters can be tough on managed honey bee colonies, with beekeepers in the United States reporting that one-third of their colonies die each winter. A new study by Penn State researchers has found that using not one but multiple pest treatments may help bees make it to spring. Winters can be tough on managed honey bee…
Declining snowfall is changing the seasonal patterns of streamflow throughout the Northern Hemisphere boosting chances of water shortages in the summer, scientists have found.
