NASA’s asteroid-blasting spacecraft has stored over 2 pounds of alien dust and rock to bring back to Earth

NASA's Osiris-Rex spacecraft captured an estimated 2 pounds of material from the asteroid Bennu, where it recently landed. The spacecraft collected so much alien dust and rock, in fact, that it couldn't close its sample-collection tool. So mission controllers raced to stow the sample to stop asteroid dust from leaking…

Preserving a Sense of Wonder in DNA Hydrogen

Preserving a Sense of Wonder in DNA

Not long ago, Joe Davis, the “artist-scientist” in George Church’s genetics lab at Harvard Medical School, was in Brittany, France. The region is known for thousand-year-old salterns that produce fleur de sel, or flower of salt—salt that forms as seawater evaporates. Davis was there sampling these brightly colored ponds with…

Airbus created a remote-controlled aircraft with flapping wingtips to see how much it could increase efficiency

Airbus' AlbatrossONE. Airbus Airbus created the AlbatrossONE, a small-scale remote-controlled aircraft with wingtips that can flap like a bird during turbulence to better handle the strong gusts of winds. These hinged, flapping wingtips help reduce drag, therefore saving fuel and consequently decreasing carbon dioxide emissions. Airbus has completed two flight…

Galactic archaeology Hydrogen

Galactic archaeology

No one has yet found the first stars. They're hypothesized to have formed about 100 million years after the Big Bang out of universal darkness from the primordial gases of hydrogen, helium, and trace light metals. These gases cooled, collapsed, and ignited into stars up to 1,000 times more massive…

Polyethylene upcycling to long-chain alkylaromatics by tandem hydrogenolysis/aromatization Hydrogen

Polyethylene upcycling to long-chain alkylaromatics by tandem hydrogenolysis/aromatization

A new future for polyethyleneMost current plastic recycling involves chopping up the waste and repurposing it in materials with less stringent engineering requirements than the original application. Chemical decomposition at the molecular level could, in principle, lead to higher-value products. However, the carbon-carbon bonds in polyethylene, the most common plastic,…
