Lost world discovered beneath Antarctic ice

A large-scale transcontinental river system from the Eocene era, dating back 44 to 34 million years ago, has been discovered beneath the Antarctic ice.

New study upends prevailing theory on transportation of Stonehenge bluestones

A new study, published in the Quaternary Newsletter journal, suggests that the Bristol Channel was a glacial transport route.

Study analyses organic material from 3.5 billion-year-old biomass

Researchers from the University of Göttingen are using high resolution techniques to trace the origin and composition of a 3.5 billion-year-old biomass.

Source of Snowball Earth solved

Geologists have solved the source of Snowball Earth, a period when the planet’s environment was an extreme "icehouse".

Study suggests that nature played a role in the origins of the Great Sphinx

The Great Sphinx of Giza is a limestone statue of a reclining sphinx, a mythical creature characterised by the combination of a human head and a lion's body.

Microfossils reveal warm oceans had less oxygen, according to Syracuse geologists

Professor Zunli Lu uses geochemistry and micropalaeontology to track oxygen levels in global oceans.

Snail shells show high-rise plateau is much lower than it used to be

The Tibetan Plateau in south-central Asia, because of its size, elevation and impact on climate, is one of the world’s greatest geological oddities.

First eyewitness accounts of mystery volcanic eruption

The eruption occurred just before the 1815 Tambora volcanic eruption, which is famous for its overwhelming impact on climate worldwide, with 1816 given memorable names such as ’Eighteen-Hundred-and-Froze-to-Death’, the ‘Year of the Beggar’ and the ‘Year Without a Summer’ due to unseasonal frosts, crop failure and famine across Europe and North America. The extraordinary conditions are considered to have inspired literary works such Byron’s ‘Darkness’ and Mary Shelley’s ‘Frankenstein’.

The Gulf Stream kept going during the last Ice Age

The warm Atlantic water continued to flow into the icy Nordic seas during the coldest periods of the last Ice Age.

Trinity geologists re-write Earth’s evolutionary history books

Geologists from Trinity College Dublin have rewritten the evolutionary history books by finding that oxygen-producing life forms were present on Earth some 3 billion years ago – a full 60 million years earlier than previously thought.

Climate change and drought in ancient times

The influence of climate on agriculture is believed to be a key factor in the rise and fall of societies in the Ancient Near East. Dr. Simone Riehl of Tübingen University’s Institute for Archaeological Science and the Senckenberg Center for Human Evolution and Palaeoenvironment has headed an investigation into archaeological finds of grain in order to find out what influence climate had on agriculture in early farming societies.

Western Wall Wearing Away? Discovery of Extreme Erosion Process Could Guide New Preservation Techniques

Researchers from the Hebrew University of Jerusalem investigated erosion in the different types of limestone in the Western Wall located at the foot of Jerusalem’s Temple Mount. Stones comprised of large crystals were almost unchanged in 2000 years, while limestone containing small crystals eroded much faster and in some cases had receded by tens of centimeters, potentially weakening the wall’s structure. The researchers describe an accelerated erosion process that explains why some rocks are more weathered than others, and displayed that chemo-mechanical erosion extends down to the tiny micron scale. The findings could have significant implications for regional and global carbonate weathering, and could help guide the development of effective preservation techniques that slow the rate of erosion in order to protect cultural heritage sites around the world.

Top 10 deadliest volcanic eruptions

Volcanoes are among the most devastating and dangerous natural forces in our past, but it is not just throughout history that they wrecked havoc on human life but right up to the 21st century. Their volatility and unreliability have changed our world’s landscape over time and also lives of the people living in their shadows. Here are listed the 10 most deadly recorded volcanic eruptions.

Decades-old amber collection offers news views of a lost world

Scientists are searching through an extremely large collection of 20-million-year-old amber unearthed in the Dominican Republic over 50 years ago; the effort is displaying new insights into ancient tropical insects and the world they lived in.

Jeju Island is a live volcano

In Jeju, renowned as an attractive holiday destination with natural tourism resources, a recent study unveiled a volcanic eruption occurred on the island. The Korea Institute of Geoscience and Mineral Resources (KIGAM) discovered traces that showed that a recent volcanic eruption was evident 5,000 years ago. That is the first time to actually find out the date when lava spewed out of a volcano 5,000 years ago in the inland part of the island as well as the one the whole peninsula.

New view of Rainier’s volcanic plumbing
