New Data about the structure of the Pyramid of Cheops
New Data about the structure of the Pyramid of Cheops
An interview with Prof. Christian Große about his pyramid research Measuring a height of 139 meters (455 ft.), the largest of the three pyramids of Giza is one of the oldest edifices in the world. Yet, even after 4,500 years, this architectural masterpiece still leaves some questions unanswered.

Tiny bubbles tell tales of big volcanic eruptions
Tiny bubbles tell tales of big volcanic eruptions
Study: Nanocrystals may explain staggering number of bubbles in erupted lava Microscopic bubbles can tell stories about Earth's biggest volcanic eruptions and geoscientists from Rice University and the University of Texas at Austin have discovered some of those stories are written in nanoparticles.

Changing resilience of oceans to climate change
Oxygen levels in the ancient oceans were surprisingly resilient to climate change, new research suggests. An international team of scientists led by ETH Zurich used geological samples to estimate ocean oxygen during a period of global warming 56 million years ago - and found limited expansion of seafloor anoxia (absence of oxygen).

Posidonia marine seagrass can catch and remove plastics from the sea
This natural mechanism could trap about 867 million plastic per year in coastal areas. Photo: Jordi Regàs In the grasslands, the plastics are incorporated to agglomerates of natural fiber with a ball shape (aegagropila or Posidonia Neptune balls). This study is pioneer in the description of a natural mechanism to take and remove these materials from the sea.

Warming and acidification form dual threat to corals
A quarter of the carbon emissions that are warming the Earth dissolve into oceans, making them more acidic. Carbon emissions and warming are also causing ocean heat waves, which in turn is bleaching the world's coral reefs. Now, a UCLA-led study reveals how increased acidity and warming ocean temperatures can interact to threaten reef-building corals.

Wastewater treatment plants retain 96 percent of mercury
Wastewater treatment plants retain 96 percent of mercury
Each year, around 130 kilograms of mercury flow into Swiss wastewater treatment plants, which filter out the lion's share from the waste water. This is shown by a survey of almost thirty wastewater treatment plants conducted by the Swiss Federal Institute of Aquatic Science and Technology (Eawag) and the Federal Office for the Environment (FOEN).

Imminent sudden stratospheric warming to occur, bringing increased risk of snow over coming weeks
Imminent sudden stratospheric warming to occur, bringing increased risk of snow over coming weeks
A new study, led by researchers at the Universities of Bristol, Exeter and Bath, helps to shed light on the winter weather we may soon have in store following a dramatic meteorological event currently unfolding high above the North Pole. Weather forecasting models are predicting with increasing confidence that a sudden stratospheric warming (SSW) event will take place today, 5 January 2021.

Muddying the waters: rock breakdown may play less role of a role in regulating climate than previously thought
Muddying the waters: rock breakdown may play less role of a role in regulating climate than previously thought
The weathering of rocks at the Earth's surface may remove less greenhouse gases from the atmosphere than previous estimates, says new research from the University of Cambridge.

New study helps pinpoint when Earth’s tectonic plates began
Every year, earthquakes shake the ground and volcanoes erupt around the edges of tectonic plates-the massive pieces of Earth's crust that slide slowly across the planet, creating and destroying mountains and oceans on the scale of eons. But the question of when this plate subduction actually began has been a hotly contested debate in earth sciences.

Warm oceans helped first human migration from Asia to North America
Warm oceans helped first human migration from Asia to North America
New research reveals significant changes to the circulation of the North Pacific and its impact on the initial migration of humans from Asia to North America. The international study, led by the University of St. Andrews in Scotland and published Dec. 9 in Science Advances, provides a new picture of the circulation and climate of the North Pacific at the end of the last ice age, with implications for early human migration.

New evidence: Neandertals buried their dead
New evidence: Neandertals buried their dead
Was burial of the dead practiced by Neandertals or is it an innovation specific to our species? There are indications in favour of the first hypothesis but some scientists remain sceptical. For the first time in Europe, however, a multi-disciplinary team led by researchers at the CNRS and the Muséum national d'histoire naturelle (France) and the University of the Basque Country (Spain) 1 has demonstrated, using a variety of criteria, that a Neandertal child was buried, probably around 41,000 years ago, at the Ferrassie site (Dordogne).

New study allows regional prediction of uranium in groundwater
New study allows regional prediction of uranium in groundwater
Stanford researchers can predict where and when uranium is released into aquifers and suggest an easy fix to keep this naturally occurring toxin from contaminating water sources. Lurking in sediments and surrounding the precious groundwater beneath our feet is a dangerous toxin: uranium. Scientists have long known this and tested for it.

Getting to the bottom of Arctic landslides
Getting to the bottom of Arctic landslides
Erosion of the frozen soil of Arctic regions, known as permafrost, is creating large areas of subsidence, which has catastrophic impact in these regions sensitive to climate change. As the mechanisms behind these geological events are poorly understood, researchers from the Géosciences Paris Sud (GEOPS) laboratory (CNRS / Université Paris-Saclay), in cooperation with the Melnikov Permafrost Institute in Yakutsk, Russia, conducted a cold room 1 simulation of landslides, or slumps, caused by accelerated breakdown of the permafrost.

Crystals may help reveal hidden Kilauea Volcano behavior
Crystals may help reveal hidden Kilauea Volcano behavior
Stanford researchers used millimeter-sized crystals from the 1959 eruption of Hawaii's Kilauea Volcano to test models that offer insights about flow conditions prior to and during an eruption. Scientists striving to understand how and when volcanoes might erupt face a challenge: many of the processes take place deep underground in lava tubes churning with dangerous molten Earth.

Scientists organize to tackle crisis of coral bleaching
Scientists organize to tackle crisis of coral bleaching
Coral reefs are among the most diverse ecosystems in the world, protecting coastlines from erosion and supporting more than 500 million people through tourism and fishing livelihoods. But at the current rate of global warming, mass coral bleaching is expected to become more frequent and severe worldwide.

Earlier than expected
Earlier than expected
Precisely when will the long-lost US aircraft "Dakota" re-emerge from the Gauli Glacier? Radioactive traces from the Cold War now indicate that this will happen soon. It was a time that left its mark: as the great powers of the 1950s and 1960s carried out above-ground tests of their nuclear weapons, radioactive substances settled on the Earth's surface all around the world.

Scientist joins next Mars adventure
Scientist joins next Mars adventure
Martian geologist Kirsten Siebach among 13 chosen by NASA for rover mission Kirsten Siebach has to persevere a little longer, waiting for her ship to come in. That ship is in space , carrying a rover called Perseverance to Mars. And Siebach, a Martian geologist at Rice University, is now one of 13 scientists recently selected by NASA to help operate the rover and scout for samples that will eventually be returned to Earth.

How Stable is the Antarctic Ice Sheet?
How Stable is the Antarctic Ice Sheet?
Scientists from Heidelberg University investigate which factors determine the stability of ice masses in East Antarctica As temperatures rise due to climate change, the melting of polar ice sheets is accelerating. An international team of researchers led by geoscientist Dr Kim Jakob from Heidelberg University has now examined the dynamics of the East Antarctic Ice Sheet more closely.

The Swiss Alps continue to rise
The Swiss Alps continue to rise
An international team of geologists, headed by members of the University of Bern, has shown for the first time that the Swiss Alps are being lifted faster than they are being lowered through erosion - and are thus growing even higher. To do this, the researchers quantified the erosion of the Alps with the help of isotopes measured in the sand of more than 350 rivers throughout the European Alps.
