• Virginia wetlands offer a “shelter from the storm”

    Floods are the most common natural disaster in the United States, causing an average of $8.2 billion in damage each year for the past thirty years. As global warming continues, scientists predict that the damage caused by floods will only increase. In Virginia, 2004’s Hurricane Gaston brought flooding which destroyed more than 5,000 homes and resulted in multiple fatalities. The storm cost an estimated $130 million in damage. Sufficient wetlands remain in Virginia to hold enough rain to cover the city of Hampton in more than thirty feet water, according to a new report by Environment Virginia Research & Policy Center. The analysis says the state’s wetlands are at risk from pollution and development, however, and so is the region’s natural shield against flood damage.

  • Water shortage grows, and so does the need for technological solutions

    The value of freshwater is becoming more apparent, as more and more areas around the world are suffering from dwindling supply as a result of climate change. The World Bank estimates that water is $1 trillion privatized commodity. Last week, California imposed mandatory restrictions on water use for the first time in its history. California’s unprecedented move is just one example of the political and social issues which will accompany a growing water shortage moving forward.

  • Cybersecurity firms hire former military, intelligence cyber experts

    Over the past two years, U.S. cybersecurity firms have brought in several former military and intelligence community computer experts to help combat hackers targeting the U.S. private sector. For the new private sector employees, the wages are higher and opportunities are endless. Hundreds of ex-government cybersecurity workers represent the competitive advantage of a cybersecurity services industry expected to bring in more than $48 billion in revenue next year, up 41 percent from 2012. “The people coming out of the military and the intelligence community are really, really good,” says a cyber startup founder. “They know the attackers. They know how they work.”

  • Shipping oil by rail is booming. Technology can make it safer

    Last year, trains transported more than one million barrels of oil per day in 2014 — a huge jump from 55,000 barrels per day in 2010. This increase in oil-by-rail transportation has come with a number of high-profile derailments. Can technology improve safety? Yes. While the risk associated with oil train derailments has not been eliminated, the transportation of crude oil by rail has certainly become safer through extensive research, development, and implementation of new technologies. Continued efforts by railroads, government agencies, research institutions, and universities will continue to improve the safety of crude oil transportation by rail, reducing risk and potentially alleviating public fears associated with railroad transportation.

  • PG&E to pay $1.6 billion in gas explosion settlement

    The California Public Utilities Commission (CPUC) has levied the largest penalty in the agency’s history on Pacific Gas and Electric Company (PG&E), ordering the company to pay $1.6 billion for failures which led to a 2010 natural gas pipeline explosion in San Bruno. The explosion killed eight people and destroyed or damaged thirty-eight homes.Afaulty weld on the pipeline caused the explosion and the resulting fire. The company may also owe an additional $1.13 billion in federal criminal fines connected to the blast, and has committed to spend $2.8 billion in reassessing pipeline safety.

  • California not the only state to face water shortage

    Over the past two weeks, California’s long drought — and Governor Jerry Brown’s mandatory water conservation rules — have captured the headlines. As the country keeps an eye on how Californians will adapt to the new reality of water conservation, other states must prepare to maintain the sustainability of their own water supplies. “As far as other states, if they haven’t seen it [water shortages] in the past, it’s something they will see in the future,” says a water policy analyst in Los Angeles.

  • Critics: PG&E downplays quake risk to Diablo Canyon nuclear plant

    Since the Diablo Canyon nuclear power plant in California was opened by Pacific Gas and Electric Co. (PG&E) in 1985, geologists have discovered three fault lines nearby, which could threaten the plant. The three faults are capable of quakes even stronger than the one which ravaged the Napa Valley last year, and critics of PG&E say the company has been minimizing the risks the three faults pose. The company rejects the criticism. The critics are now suing to company to force it to reapply for an operating license – with the information about the three faults included in the application.

  • Scientists develop deep borehole disposal (DBD) method to deal with nuclear waste

    Technologies which will enable nuclear waste to be sealed five kilometers below the Earth’s surface could provide a safer, cheaper and more viable alternative for disposing of the U.K.’s high level nuclear waste. Scientists calculate that all of the U.K.’s high level nuclear waste from spent fuel reprocessing could be disposed of in just six boreholes five kilometers deep, fitting within a site no larger than a football pitch. The concept — called deep borehole disposal — has been developed primarily in the United Kingdom, but is likely to see its first field trials in the United States next year.

  • Big data technology helps identify best river locations for hydro-power generation

    A new technology has the potential to revolutionize the sourcing of renewable energy from rivers. The software app automatically selects appropriate locations in U.K. rivers to site a large range of micro renewable hydro-power turbines in these rivers, and determines the environmental sensitivity of the location.

  • San Diego to build largest ocean desalination plant in Western Hemisphere

    San Diego County, California will soon become home to a $1 billion desalination plant which would supply drinking water to residents currently having to cut their water consumption by as much as 25 percent in response to the state’s current drought. Small ocean desalination plants already operate throughout the state, but the facility being built in San Diego will be the largest ocean desalination plant in the Western Hemisphere, producing roughly fifty million gallons of drinking water a day.

  • Cyber espionage campaign, likely sponsored by China, targets Asian countries: FireEye

    FireEye has released a report which provides intelligence on the operations of APT 30, an advanced persistent threat (APT) group most likely sponsored by the Chinese government. APT 30 has been conducting cyber espionage since at least 2005, making it one of the longest operating APT groups that FireEye tracks. APT 30 targets governments, journalists, and commercial entities across South East Asia and India.

  • Extreme geohazards: Reducing disaster risk, increasing resilience

    Extreme hazards — rare, high-impact events — pose a serious and underestimated threat to humanity. The extremes of the broad ensemble of natural and anthropogenic hazards can lead to global disasters and catastrophes. Because they are rare and modern society lacks experience with them, they tend to be ignored in disaster risk management. While the probabilities of most natural hazards do not change much over time, the sensitivity of the built environment and the vulnerability of the embedded socio-economic fabric have increased rapidly.

  • Virtual guard detects real-time leaks in water, oil-, or gas pipes

    Often, water, gas, or oil distribution networks suffer from leaks in storage tanks, pumping failures, or illegal tapping. In order to prevent losses which typically result, researchers designed a virtual guard which immediately detects abnormalities in any type of duct. Through the laws of physics and application of a mathematical model of fluid mechanics, the device calculates when an irregularity occurs on site, and issues an alert.

  • Doubts about burying CO2 underground to address climate change

    Burying the greenhouse gas carbon dioxide, a byproduct of burning fossil fuels, has been mooted as one geoengineering approach to ameliorating climate change. To be effective, trapping the gas in geological deposits would be for the very long term — thousands of years. Now, researchers have reviewed the risk assessments for this technology, suggesting that a lack of knowledge means we should be cautious of turning to this method rather than finding sustainable ways to reduce emissions at their source.

  • Joplin, Missouri hospital re-built to withstand powerful tornadoes

    In 2011 St. John’s Medical Center in Joplin, Missouri was devastated by one of the most ferocious tornadoes in U.S history. Today, Mercy Hospital Joplinstands on the site of the former hospital, occupying a new structure designed to survive future tornadoes, with windows that can withstand 250-mile-per-hour winds. The buildingis covered in concrete and brick paneling, and houses an underground bunker where generators and boilers are kept.
