UCLA researchers say they've found a way to reduce mineral sunscreen's biggest drawback: the white cast.
Why it matters: The chalky residue — especially on darker skin tones — keeps many people from wearing mineral sunscreen, despite its role in preventing skin cancer.
The Trump administration's aim to build a U.S. strategic reserve of critical minerals for commercial use opens a new front in U.S. efforts to ease reliance on China.
Why it matters: It's designed to protect domestic manufacturers from supply shocks.
While most of the South is bouncing back from the ongoing winter storms, the crisis in Nashville and parts of Mississippi is dragging into another week, with at least 37 dead and tens of thousands still without power.
Why it matters: Unlike Texas in 2021, power generation held up. The failures were more mundane: Icy trees snapped power lines, and crews struggled to reach damaged poles. That's left a patchwork recovery: Most of the region is recovering, but tens of thousands remain stuck without heat in freezing temperatures.
As the world steamrolls toward more nuclear power, countries looking to cut costs must do a better job of planning — in part by building reactors in factories instead of on site, a new study says.
Why it matters: The Nuclear Innovation Alliance study says a successful nuclear build-out could slash costs similar to the way the aerospace industry did decades ago while "unlocking the scale of low-carbon power needed for global decarbonization."
