Science reveals improvements in Roman building techniques

The Romans were some of the most sophisticated builders of the ancient world. Over the centuries, they adopted an increasingly advanced set of materials and technologies to create their famous structures. To distinguish the ...

How and when was carbon distributed in the Earth?

It is generally accepted that planetary surfaces were covered with molten silicate, a "magma ocean," during the formation of terrestrial planets. In a deep magma ocean, iron would separate from silicate, sink, and eventually ...

Why is the Earth's F/Cl ratio not chondritic?

Primitive chondrites, un-molten stony meteorites, are believed to be the building blocks of the Earth. Because terrestrial planets have experienced chemical differentiation in the core, mantle, and hydrosphere, the elemental ...

A volcanic binge and its frosty hangover

A major volcanic event could have triggered one of the largest glaciations in Earth's history—the Gaskiers glaciation, which turned the Earth into a giant snowball approximately 580 million years ago. Researchers from Heidelberg ...

What magnetic fields can tell us about life on other planets

Every school kid knows that Earth has a magnetic field – it's what makes compasses align north-south and lets us navigate the oceans. It also protects the atmosphere, and thus life, from the sun's powerful wind.

Chemist obtains a nanocatalyst base from rice husk

A chemist from RUDN has developed a method to obtain high-porosity silicium dioxide, a base for nanocatalysts used in different types of organic reactions, from rice husks. The results of the study were published in ACS Sustainable ...
