President Donald Trump’s fiscal 2026 budget request, if approved by Congress, would kill many of NASA’s plans for robotic ...

A molecular reinterpretation of Alice in Wonderland reveals an ancient protein with a surprising function. In a ...

Water is everywhere and comes in many forms: snow, sleet, hail, hoarfrost, and so on. However, despite water being so ...

In chaos terrains like Tara Regio, the presence of strange chemicals—including table salt and carbon dioxide—suggests that ...

At some point, RNA must have replicated itself before the evolutionary arrival of DNA and proteins, and now we might know how ...

helps scientists understand how water behaves in extreme planetary environments. What Makes Plastic Ice VII Unique? Unlike regular ice, Plastic Ice VII has a rigid structure but allows molecular ...

A mysterious byproduct of a chemical used to disinfect the tap water of about one-third ... unable to isolate it and determine its molecular formula or structure. Using more-advanced technologies ...

Let us dive into the science behind it. At the core of understanding why ice floats is the unique molecular structure of water. Water (H₂O) consists of two hydrogen atoms and one oxygen atom.

There are water molecules, the compound we know as H2O; its frozen form, ice; and a molecular compound called hydroxyl, a close chemical relative. Previous discoveries suggested that water had ...

The colder that water gets, the smaller this energy barrier gets. This makes it easier for random molecular motions to push a tiny embryonic ice structure over the critical size threshold. Ice forms ...

Normally, ice is made up of crinkled layers: Some water molecules in each layer are lower, and some higher. But the team found places where water molecules lined up in a plane, a structure that se ...
