Phys.org / From fleeting to stable: Scientists uncover recipe for new carbon dioxide-based energetic materials

When materials are compressed, their atoms are forced into unusual arrangements that do not normally exist under everyday conditions. These configurations are often fleeting: when the pressure is released, the atoms typically ...

Phys.org / A brief history of sugar

A few thousand years ago, sugar was unknown in the western world. Sugarcane, a tall grass first domesticated in New Guinea around 6000BC, was initially chewed for its sweet juice rather than crystallized. By around 500BC, ...

Phys.org / Cryo-EM structures reveal conformational dynamics behind AP-4 membrane trafficking

Adaptor protein (AP) complexes play central roles in intracellular vesicular trafficking by coupling cargo selection to vesicle formation. AP-4, an important member of the AP family, plays a key role in this process. AP-4 ...

Phys.org / New data show reduced overall PFAS exposures in subarctic ocean

Beginning in the early 2000s, some of the most common and well-studied PFAS were phased out through a combination of industry shifts and international regulations. A new study from Harvard has found that since that phaseout, ...
