Magma-limestone interaction can trigger explosive volcanic eruptions -- and affect the global carbon cycle
In a new study researchers from Sweden and Italy show what happens when magma meets limestone on its way up to the surface. Magma-limestone interaction might help explain why volcanoes like Vesuvius in Italy and Merapi in Indonesia are particularly explosive and, moreover, it helps us to understand another source of natural carbon released to the atmosphere by volcanoes.

Cement as a climate killer: Using industrial waste to produce carbon neutral alternatives
Producing cement takes a big toll on our climate: Around eight per cent of annual global carbon dioxide emissions can be attributed to this process. However, the demand for cement continues to rise. A team of geoscientists from Martin Luther University Halle-Wittenberg (MLU) has found a way to produce more environmentally friendly and sustainable alternatives. In the journal ''Construction and Building Materials'' they describe how industrial residues can be used to produce high-quality, climate-friendly materials. (2019-05-20)

Meteorites rained on Earth after massive asteroid breakup
Using fossil meteorites and ancient limestone unearthed throughout southern Sweden, marine geologists at Rice University have discovered that a colossal collision in the asteroid belt some 500 million years ago led to intense meteorite strikes over the Earth's surface. The research, which appears in this week's issue of Science magazine, is based upon an analysis of extraterrestrial minerals and fossils found in limestone that formed from sea bottom sediments about 480 million years ago.

Compost establishes growing media pH similar to limestone
Researchers determined the resulting substrate pH when using a range of compost and limestone rates, and compared the pH buffering capacity of substrates that had the pH established by the addition of compost, limestone, or a combination of both. Results demonstrated that compost can be used to establish horticultural growing substrate pH similar to limestone with little to no effect on pH buffering capacity. (2016-11-28)

Carbon dioxide stored underground can find multiple ways to escape
When carbon dioxide is stored underground in a process known as geological sequestration, it can find multiple escape pathways due to chemical reactions between carbon dioxide, water, rocks and cement from abandoned wells, according to Penn State researchers. (2016-02-11)

Volcano taming
Could macro-scale chemical engineering be used to stop a volcanic lava flow in its tracks and save potentially thousands of lives and homes when the next eruption occurs? That's the question R. D.

Western Wall weathering: Extreme erosion explained
Hebrew University researchers investigating erosion at Jerusalem's Western Wall found that limestone with very small crystals eroded up to 100 times faster and had sometimes receded by tens of centimeters, potentially weakening the wall's structure. The researchers described an accelerated erosion process causing some rocks to become more weathered than others, and showed that chemo-mechanical erosion extends down to the tiny micron scale. The findings could help guide preservation techniques at cultural heritage sites worldwide. (2014-08-11)

A new, greener cement to meet future demand
Cement production is responsible for almost 10 percent of human CO2 emissions. Nevertheless, it is one of the most sustainable construction materials. Now, an EPFL-led consortium has received backing from the Swiss Agency for Development and Cooperation to speed up the development and testing of a new blend of low-carbon cement, which substitutes up to half of the usual Portland cement used to make concrete with highly abundant clay and limestone, promising to reduce cement-related CO2 emissions by up to 40 percent.

Brazilian zoologists discovered the first obligate cave-dwelling flatworm in South America
Typical cave-dwelling organisms, unpigmented and eyeless, were discovered in a karst area located in northeastern Brazil. The organisms were assigned to a new genus and species of freshwater flatworm and may constitute an oceanic relict. They represent the first obligate cave-dwelling flatworm in South America. The genus and species names honor a Hungarian biologist who immigrated to Brazil and studied freshwater flatworms over many years. The study was published in the open access journal ZooKeys.

Value-added sulfur scrubbing
Power plants that burn fossil fuels remain the main source of electricity generation across the globe. Modern power plants have scrubbers to remove sulfur compounds from their flue gases, which has helped reduce the problem of acid rain. Now, researchers in India have devised a way to convert the waste material produced by the scrubbing process into value-added products. They describe details in the International Journal of Environment and Pollution. (2010-10-21)

Malaysian microjewels going extinct as they are discovered
A Malaysian-Dutch team of biologists has cataloged 31 species of Asian Plectostoma snail, among which ten new to science. These bizarrely shaped minuscule land snails live only on limestone hills, many of which are threatened by quarrying. One species is already extinct and another, discovered and described in the new paper, will probably be gone by the end of 2014. The study was published in the open-access journal ZooKeys.

Crab from the Chinese pet market turns out to be a new species of a new genus
Shimmering carapaces make crabs attractive to pet owners. To answer the growing demand, fishermen collect and trade crustaceans, often not knowing what exactly they have handed over to their clients. Luckily for science and nature alike, however, the authors of a paper now published in the open-access journal ZooKeys have spotted such a crab and recognized its peculiarities to prove it as a new species and even a new genus from southern China.
