Using a type of bacteria that is typically found near active volcanoes researchers mix them into the concrete along with calcium lactate.
Using a type of bacteria that is typically found near active volcanoes, and near soda lakes like those near Wadi Natrun in Egypt, the researchers mix the bio material into the concrete as it is made.
The bacteria are adapted specially to extremely alkaline environments, and can survive dormant inside the concrete for years.
#Solar activity is linked NOT to global warming: Sunspot theory of climate change is the result of an ancient error in the data The theory that solar activity is linked to rising global temperatures has been cast into doubt after scientists corrected an ancient error in the calculations.
Until now, the general consensus was that solar activity-in particular sunspots -and temperatures have been trending upwards since the harsh winters of the 17th century when the spots were thought to have been at a low.
suggesting climate change cannot be plotted using this sunspots method. Scroll down for video In fact, solar activity appears to have remained relatively stable

The discovery was made by analysing data sent back from Nasa Lunar Atmosphere and Dust environment Explorer,
when giant pools of magma greater than 100 cubic miles in volume and formed a few miles below the surface will erupt.
They occur when giant pools of magma greater than 100 cubic miles in volume form a few miles below the surface
The most recent super-eruption took place about 27,000 years ago in New zealand, well before humans kept records of volcanic eruptions and their aftermath.
and how rapidly these magma bodies develop and what causes them to eventually erupt. Despite considerable study, geologists are still debating how quickly these magma pools can be activated and erupted
with estimates ranging from millions to hundreds of years. Now a team of geologists have developed a new'geospeedometer'that they argue can help resolve this controversy by providing direct measurements of how long the most explosive types of magma existed as melt-rich bodies of crystal-poor magma before they erupted.
They have applied their new technique to two super-eruption sites and a pair of very large eruptions and found that it took them no more than 500 years to move from formation to eruption.
Timekeepers of short-lived giant magma bodies'appearing in the November issue of the journal Geology.
'said Guilherme Gualda, associate professor of earth and environmental sciences at Vanderbilt University, who directed the project.'
'The measurements that have been made indicate that this magma body doesn't currently have a high-enough percentage of melt to produce a super-eruption.
The researchers'geospeedometer is sized based on millimeter quartz crystals that grew within the magma bodies that produced these giant eruptions.
Quartz crystals are typically found in magmas that have a high percentage of silica. This type of magma is very viscous
and commonly produces extremely violent eruptions. Mount st helens was a recent example. When the crystals form
they often capture small blobs of molten magma known as blebs or melt inclusions. Blebs are initially round.
While the crystal is floating in hot magma, diffusion causes them to gradually acquire the polygonal shape of the crystal void that they occupy.
SCIENTISTS FIND MASSIVE NEW MAGMA CHAMBER UNDER YELLOWSTONE In the heart of Yellowstone national park a supervolcano releases around 45,000 metric tonnes of carbon dioxide each day.
But the magma chamber lying directly beneath its surface is considered not large enough to produce such levels,
Previous research found a relatively small magma chamber, known as the upper-crustal magma reservoir, directly beneath the surface in 2013 that measures 2

to calculate how long the crystal existed in the magma before the eruption, 'said Pamukcu. In addition, the researchers compared the results obtained with faceting with results obtained using other techniques.
as long as they erupt magmas that contain quartz crystals, 'said Pamukcu.''We are also confident that we can adapt these techniques to work with other minerals,
which will allow us to make similar timescale calculations for other types of magmas and volcanoes,

#New Building material Twice as Strong as Concrete, Low Carbon footprint Watershed Materials, a California-based building materials technology startup, has developed technology to produce high-strength masonry with a low carbon footprint
Traditional concrete masonry has a high carbon footprint due to its reliance on Portland cement a material responsible for 6 percent of the world CO2 EMISSIONS.
Geopolymers are a new technology that provide an alternative to Portland cement used in concrete and masonry.
These industrial waste products are available only adjacent to coal fired power plants and steel production facilities, and the world does not produce enough to meet demand for concrete products.
Researchers at Switzerland Ecole Polytechnique Federal de Lausanne are also testing a low-carbon cement that could reduce the carbon footprint of construction sites by 40 percent, Forbes reported last year s
#Wastewater treatment Captures Carbon emissions, Produces Energy A wastewater treatment process developed by engineers at the University of Colorado Boulder mitigates carbon dioxide emissions and actively captures greenhouse gases.

#In Historic Turn, CO2 EMISSIONS Flatline in 2014, Even as Global economy Grows A key stumbling block in the effort to combat global warming has been the intimate link between greenhouse gas emissions and economic growth.
