We summarize the week's scientific breakthroughs every Thursday.
Earth’s core could contain helium from the early solar system. The noble gas tucks into gaps in iron crystals under high pressure and temperature.
Chemists identify a single molecule that naturally tiles in nonrepeating patterns, which could help build materials with novel electronic properties.
Mars may once have held enough water to fill oceans and form coastlines. The planet’s red dust contains water and likely formed in cold conditions.
Urban wildfires like LA’s make harmful chemicals from burning plastics and electronics that can make indoor air dangerous for months.
The nonplastic polymer cleaned up eyeliner and permanent marker and broke down into molecules related to sugar and amino acids.
Sheep that eat death camas plants record the toxic meal in their earwax, a goopy health data repository that researchers are increasingly exploring.
The fibers, made from white flour and formic acid, average just 372 nanometers in diameter and might find use in biodegradable bandages.
Chlorine-based water treatments create many by-products, but one has been elusive. Its identification sets the stage for studying its health effects.
Tweaking the chemical composition of a parrot-specific pigment can shift feathers from red to yellow or green.
