Ocean changes almost starved life of oxygen 800 million years ago

Chemical changes in the oceans more than 800 million years ago almost destroyed the oxygen-rich atmosphere that paved the way for complex life on Earth, new research suggests.

Hydrogen energy at the root of life

Since the discovery of submarine hydrothermal vents around 40 years ago, these natural chemical reactors have been a focus for evolutionary researchers searching for the origin of life.

Scientific research will help to understand the origin of life in the universe

Until now, in the scientific community there has been the prevailing view that thermal processes associated exclusively with the combustion and high-temperature processing of organic raw materials such as oil, coal, wood, garbage, food, tobacco underpin the formation of PAHs.

Scientists tracking the ‘life signature’ of Britain

The British Geological Survey has just released a new interactive web tool that maps out the geographical variation in the isotope signatures of Britain.

Italy’s oldest olive oil discovered in peculiar pot

 Olive oil is a staple of Italian cuisine. It's been that way for thousands of years. And new chemical analysis conducted on ancient pottery proves the liquid gold has existed in Italy hundreds of years longer than what anthropologists have previously recorded.

Earliest European evidence of lead pollution uncovered in the Balkans

New research from Northumbria University has revealed that metal-related pollution began in the Balkans more than 500 years before it appeared in western Europe, and persisted throughout the Dark Ages and Medieval Period, meaning the region played a far bigger role in mineral exploitation than previously believed.

Geologists assist in solving the mystery of a gold treasure

The Carambolo Treasure is an assemblage of gold items of the first millennium BCE, whose origin has for about 50 years been the epicentre of a heated debate.

Experiment sheds new light on prehistoric ocean conditions

A new experiment by Iowa State University's Elizabeth Swanner that evaluates the reduction of iron in prehistoric oceans may reinterpret the conditions under which iron-rich sedimentary rock is formed.

Prehistoric bling? Aesthetics crucial factor in development of earliest copper alloys

Research into ancient gold metallurgy has been supported by various studies, however, colour properties of prehistoric copper alloys such as arsenical copper and tin have remained largely understood.
