• Using earthquake research to refine fracking methods

    Researchers at Oklahoma State University (OSU) are using historical earthquake data to make oil and natural gas drilling more efficient. Members of the university research team found that hydraulic fracturing, or fracking, a process in which water and sand are blasted at high pressure into rock to remove oil, can cause an effect similar to earthquakes. Data gleaned from historical earthquake experiences have told scientists much about what happens to the rock during such events – and the knowledge may allow oil companies to understand how to extract gas without also removing groundwater.

  • DOJ’s new cyber unit to provide legal guidance on electronic surveillance

    The Justice Department is creating a cybersecurity unit within its Computer Crime & Intellectual Property Section (CCIPS) to provide legal guidance on electronic surveillance investigations.The unit will also work with Congress on cybersecurity legislation and focus on cybercrime prevention.

  • Improving nuclear power plant safety by looking at nature

    Within the nuclear industry, hazardous salt solutions can arise within industrial containment vessels. The salt solution precipitates out, forming structures with strange morphologies that bear a resemblance to stalagmites. If left unchecked, they could build up and cause a problem in the nuclear containment chamber. Currently, these containment chambers are checked regularly to prevent this from happening. Taking inspiration from nature, researchers have created a versatile model to predict how stalagmite-like structures form in nuclear processing plants — as well as how lime scale builds up in kettles.

  • Risks of terrorists attacking, or using materials from, a nuclear power plant are low: Experts

    Energy analysts who support new nuclear power plants construction insist that the probability of a terrorist nuclear attack by land, sea, or air is extremely low. They reject arguments by nuclear power opponents that terrorist groups may one day attack a nuclear plant, or build an improvised nuclear bomb using materials stolen from a nuclear power plant – and that governments should, therefore, end construction of new nuclear power plants. Climate scientists supporting reduction in CO2 emissions wrote that “There is no credible path to climate stabilization that does not include a substantial role for nuclear power.”

  • Washington State supports new Hanford project, but worries about cost

    The state of Washington is supporting a new facility which would lessen the load on the Hanford vitrification (vit) plant to process nuclear waste, but has expressed concerns about how the U.S. Department of Energy (DOE) will pay for the project. Only rough estimates of the cost of the project – called LAWPS, or the Low-Activity Waste Pretreatment System — have been made, but these estimates run between $243 million and $375 million, though that number does not include infrastructure costs such as the addition of roadways and utility services.

  • Micro-capsules and bacteria used in self-healing concrete

    Researchers are aiming to develop a novel self-healing concrete that uses an inbuilt immune system to close its own wounds and prevent deterioration. Self-healing concrete could vastly increase the life of concrete structures, and would remove the need for repairs, reducing the lifetime cost of a structure by up to 50 percent. Over seven per cent of the world’s CO2 emissions are caused by cement production, so reducing the amount required by extending the lifetime of structures and removing the need for repairs will have a significant environmental impact.

  • CO2 warming effects already felt a decade after being emitted

    It takes just ten years for a single emission of carbon dioxide (CO2) to have its maximum warming effects on the Earth. This is according to researchers who have dispelled a common misconception that the main warming effects from a CO2 emission will not be felt for several decades. This means that the benefits from emission reductions — the avoidance of extreme weather events such as droughts, heatwaves, and flooding — will be felt by those who have worked to curb the emissions and not just future generations. Some of the bigger climate impacts from warming, however, such as sea-level rise, melting ice sheets, and long-lasting damage to ecosystems, will have a much bigger time lag.

  • Research shows how global warming links to carbon emissions

    A team of researchers from the Universities of Liverpool, Southampton, and Bristol have derived the first theoretical equation to demonstrate that global warming is a direct result of the build-up of carbon emissions since the late 1800s, when man-made carbon emissions began. The results are in accord with previous data from climate models. The results show every million-million tons of carbon emitted will generate one degree Celsius of global warming. They also show that the build-up of carbon emitted over the last 200 years will then last for many centuries to millennia even if carbon emissions are subsequently phased out.

  • Southeastern Louisiana has a problem: "The sea is rising and the land is sinking"

    Southeastern Louisiana is drowning at the rate of one football field per hour, totaling up to sixteen square miles annually. In just eighty years, sea level rise, fossil fuel extraction, and having too few wetlands separating the Gulf from the flood protection levee systems have caused some 2,000 square miles of Louisiana’s coastal landscape to sink into the Gulf of Mexico. The issues facing Louisiana’s southeastern coast pose a threat to American energy and economic stability. A $50 billion, 50-year coastal restoration plan, formulated in 2007, is yet to be accepted and funded, but experts note that if sea-level rise is as bad as the worst case scenario, several projects at the heart of the restoration plan would become infective.

  • Nimble robot expedites, simplifies water pipe inspections

    See video

    Between 30 and 50 percent of Europe’s drinking water are being lost every year due to pipe leakages. Norwegian researchers have developed an inspection methodology for water distribution grids. A long, torpedo-like and propeller-driven robot is guided through the water and district heating pipe systems. It is equipped with sixty-four large ultrasound transducers which transmit and receive ultrasound signals. It collects data which enable us calculate the thickness of, and levels of corrosion in, the pipes.

  • Debate over California’s Salton Sea rescue plan coming to a head

    The California State Water Resources Control Board (SWRCB) is currently reviewing a plan to arrest the deterioration of the Salton Sea, a shallow, saline lake which runs along the state’s Imperial and Coachella valleys above the San Andreas Fault. The Salton Sea was inadvertently created by engineers with the California Development Company when they cut off a series of canals in an effort to manage river flooding between 1904 to 1906. It has since been a popular vacation destination.

  • A solution to the U.S. water problem: People who use more water, pay more

    Approximately one-third of the United States is in at least a moderate state of drought. Exacerbating the drought is a rapidly increasing population. The U.S. Census Bureau estimates the country’s population will balloon from nearly 310 million in 2010 to more than 420 million in 2060. Experts say that current levels of water consumption cannot continue. One expert says that seasonally adjusted increasing block rates could be the answer. In short, people who use more water, pay more.

  • Egypt thwarts terrorist attack on Israeli gas platforms in the Mediterranean Sea

    Egypt said it had thwarted an attempt by Islamic State (ISIS)-affiliated Egyptian terrorists on 12 November to attack Israeli energy platforms in the Mediterranean Sea. The terrorists, members of the Ansar Bayt al-Maqdis terror group which operates in the Sinai Peninsula, commandeered an Egyptian navy missile boat for the planned attack. Other Egyptian navy vessels gave chase and stopped the commandeered missile boat, killing eight aboard in a heavy exchange of fire. In addition to attacking Israeli gas platform, the terrorists planned to attack Israeli ships.

  • Mobile radio passive radar helps protect ports, coastal communities

    Airports are subject to careful security surveillance, but many coastal towns and ports are not; they often lack radar installations to keep track of small boats, meaning that terrorists could easily use speedboats to approach the coastline and bring explosives on land. Now, researchers have developed a passive surveillance system for littoral regions based on mobile radio illumination called Passive Coherent Location (PCL). It passively employs the continuous radio signals emitted by cell towers to detect suspicious boats, including those speedboats favored by pirates for approaching cargo ships. The fusion with electro-optical or infrared systems allows the classification of the different targets.

  • New online sensor improves quality check of drinking water

    A Dutch doctoral candidate has developed an online sensor which can be used to check the quality of the water in a water purification plant more accurately and more cheaply. Amongst other things, the sensor can measure the amount of rust, salts, bacteria, or alcohol a liquid contains. With this sensor the water purification companies and other companies can save a lot of money, as they can better assess when they have to replace or clean the installations and pipes.
