Clathrate hydrates are crystalline structures formed at the bottom of seafloors, created by water molecules trapping methane, ...

Mars appears as a red-orange globe with darker blotches and white icecaps visible on both of its poles. Mars appears as a red-orange globe with darker blotches and white icecaps visible on both of its ...

The ice in a domestic freezer is remarkably different from the single crystals that form in snow clouds, or even those formed on a frozen pond. As temperatures drop, ice crystals can grow in a variety ...

Researchers have developed a new way to control and manipulate optical signals by embedding a liquid crystal layer into waveguides created with direct laser writing. The new devices enable ...

Metal-organic frameworks (MOFs) are porous structures composed of metal ions (or clusters) and organic linker molecules—much ...

A new climate model suggests that ancient lakes on Mars may have survived for decades beneath thin layers of ice that formed and melted with the seasons. The findings help resolve a long-standing ...
