Why the energy transition won't be green until mine waste disasters are prevented

On February 18, contamination in the Kafue river, Zambia, led to a mass death of fish. Its water turned a deathly gray and adjacent farmland was poisoned. The drinking water it supplied to half a million residents of the ...

Dark energy may not be constant—this discovery could undermine our entire model of cosmological history

The great Russian physicist and Nobel laureate Lev Landau once remarked that "cosmologists are often in error, but never in doubt." In studying the history of the universe itself, there is always a chance that we have got ...
