Phys.org / Corals reveal 100-year warming history of the Pacific Ocean

Earth's oceans are a complex system of interconnected transport highways for heat, nutrients and the transfer of carbon dioxide between the atmosphere and sea. Meridional overturning circulation is the process by which these ...

Phys.org / Some alloys don't change size when heated, and we now know why

Nearly every material, whether it is solid, liquid, or gas, expands when its temperature goes up and contracts when its temperature goes down. This property, called thermal expansion, makes a hot air balloon float, and the ...

Phys.org / Chemists develop next-generation self-healing plastic that's also biodegradable

Imagine a plastic that is harder than common plastics, non-flammable, and even has self-healing properties. But that is not all—it can be produced at room temperature in water, which is very energy-efficient and does not ...
