• Efforts to improve cyber information sharing between the private sector, government

    Lately, Obama administration officials having been venturing West to encourage tech firms to support the government’s efforts to improve cyber information sharing between the private sector and government agencies. The House of Representatives last week passed two bills to advance such effort. The Protecting Cyber Networks Act and the National Cybersecurity Protection Advancement Act of 2015 authorize private firms to share threat data such as malware signatures, Internet protocol addresses, and domain names with other companies and the federal government. To the liking of the private sector, both bills offer companies liability protection for participating in cyberthreat information sharing.

  • Nepal shows its vulnerability after devastating earthquake

    For some time scientists have realized that the Kathmandu valley is one of the most dangerous places in the world, in terms of earthquake risk. And now a combination of high seismic activity at the front of the Tibetan plateau, poor building standards, and haphazard urbanization have come together with fatal consequences.

  • Oklahoma scientists warn about fracking-induced earthquakes

    Using stronger language than in the past, the Oklahoma Geological Survey (OGS) announced on Tuesday that the state’s ongoing waves of earthquakes are “very unlikely to represent a naturally occurring process.” The OGS says that fracking was likely a cause for the increased seismicity. The state’s seismicity rate in 2013 was seventy times greater than the rate before 2008, and rapidly grew to about 600 times greater today, according to the OGS. The average oil well in Oklahoma requires about ten barrels of saltwater to be injected for every barrel of oil that can be pumped out.

  • France’s flagship nuclear power reactor hobbled by mishaps, delays

    France’s position as a leader in the nuclear energy industry is being undermined by the country’s pending flagship nuclear reactor, which may be delayed by another year following a series of setbacks. The third-generation European Pressurized Reactor (EPR), built by Areva and EDF, was meant to be in operation by 2012 and its designers claimed it would be one of the safest — built to resist the impact of a commercial airliner crash — and the most energy efficient reactors in the world. EPR was to represent France’s nuclear renaissance, a vision to replace the country’s aging nuclear plants over time. The renaissance, however, has faced several setbacks, mishaps, and delays.

  • U.S. action on climate change hobbled by economics and politics, not divided science: Study

    The U.S. Congress successfully hears the “supermajority” consensus on the reality and causes of climate change, according to new research, which analyzed 1,350 testimonies from 253 relevant congressional hearings from 1969 to 2007. Among expert witnesses who expressed a view, 86 percent say that global warming and climate change is happening and 78 percent say it is caused by human activity. Under Republican-controlled Congresses, a three-quarter supermajority of scientists say that global warming and climate change are real and anthropogenic. Most significant of all, 95 percent of scientists giving testimonies support action to combat it. “Different perceptions and claims among lawmakers are a major hurdle to agreeing on action to address global warming and these were thought to simply reflect scientific uncertainty,” says one of the authors. “However, our findings show that congressional testimonies are in fact consistent with agreement in the climate science community and that the sources of controversies must lie elsewhere.”

  • New insights on man-made earthquakes

    Earthquake activity has sharply increased since 2009 in the central and eastern United States. The increase has been linked to industrial operations that dispose of wastewater by injecting it into deep wells. Significant strides in science have been made to better understand potential ground shaking from induced earthquakes, which are earthquakes triggered by man-made practices.

  • U.S. says South Africa’s weapon-grade uranium not sufficiently secure

    In the early 1990s South Africa’s former apartheid government dismantled the country’s six nuclear bombs and its nuclear weapons-making infrastructure as it began planning the transformation of the country into a democracy. The nuclear fuel, extracted from the country’s nuclear weapons, has over time been used to make medical isotopes, but roughly 485 pounds remain. A November 2007 breach at the Pelindaba nuclear research center, where the nuclear fuel is stored in a former silver vault, alarmed U.S. officials, who had reason to believe the culprits were after the center’s fuel inventory. Incentives from the Obama administration for South Africa to convert its nuclear-weapons fuel, have been rejected by South Africa.

  • Energy companies prime targets for hackers

    A third of the cyber incidents handled in 2014 by DHS’s Industrial Control Systems Cyber Emergency Response Team involved energy companies. Oil and gas operators face the greatest cyber risks among energy producers because their projects often involve multiple companies working together, sharing information, and trying to integrate systems. Still, 60 percent of energy companies around the world said they do not have a cyberattack response plan.

  • International experts analyze impacts of Ethiopian dam

    A new report addresses potential effects of huge construction project. According to present plans, the Grand Ethiopian Renaissance Dam (GERD) — now under construction across the Blue Nile River in Ethiopia — will be the largest hydroelectric dam in Africa, and one of the twelve largest in the world. But controversy has surrounded the project ever since it was announced in 2011 — especially concerning its possible effects on Sudan and Egypt, downstream nations that rely heavily on the waters of the Nile for agriculture, industry, and drinking water.

  • More than 143 million Americans at risk from earthquakes

    More than 143 million Americans living in the forty-eight contiguous states are exposed to potentially damaging ground shaking from earthquakes, with as many as twenty-eight million people in the highest hazard zones likely to experience strong shaking during their lifetime, according to new research. The research puts the average long-term value of building losses from earthquakes at $4.5 billion per year, with roughly 80 percent of losses attributed to California, Oregon, and Washington. By comparison, FEMA estimated in 1994 that seventy-five million Americans in thirty-nine states were at risk from earthquakes. In the highest hazard zones, the researchers identified more than 6,000 fire stations, more than 800 hospitals, and nearly 20,000 public and private schools that may be exposed to strong ground motion from earthquakes.

  • Alpine fault earthquake in New Zealand will produce challenges

    A New Zealand geological sciences researcher says an alpine fault earthquake is likely to be markedly different to the Canterbury, New Zealand earthquakes, with infrastructure losses potentially exposing the regional economy rather than the concentrated building losses seen in Christchurch in 2010 and 2011. The geologist says post-disaster recovery for an alpine fault earthquake will need to focus on rapid re-installation of critical lifelines in order to sustain the South Island economy.

  • Combination of gas field fluid injection and removal likely cause of 2013-14 Texas quake

    Seismologists found that high volumes of wastewater injection combined with saltwater (brine) extraction from natural gas wells is the most likely cause of earthquakes occurring near Azle, Texas, from late 2013 through spring 2014. SMU seismologists have been studying earthquakes in North Texas since 2008, when the first series of felt tremors hit near DFW International Airport between 30 October 2008 and 16 May 2009. Next came a series of quakes in Cleburne between June 2009 and June 2010, and this third series in the Azle-Reno area northwest of Fort Worth occurred between November 2013 and January 2014. The SMU team also is studying an ongoing series of earthquakes in the Irving-Dallas area that began in April 2014.

  • Changing human behavior key to tackling California drought: Expert

    California is experiencing a drought that has gone far beyond a “dry spell,” and the state has imposed the first water restriction in state history, aiming to cut back on water consumption by 25 percent. One expert says that strict water conservation measures are long overdue, and that “what is happening is a realization that you can’t simply transplant another ecosystem onto a California desert system or arid southwestern system. In a sense, California and much of the U.S. southwest are living beyond their ecological means. Certain lifestyles have been adopted and crops are being grown that are not endemic or sustainable for this particular bioregion.” He adds: “This is a moment for not just cutting off personal water use and turning the tap off when you’re brushing your teeth, as important as that is. This is a moment of reflection, invitation and, I hope, legislation that will cause people to think about water use in the industrial sector too. This is for the long-term prosperity of the state and sustainability of the ecosystem.”

  • Readying California’s infrastructure for the 21st century

    California’s infrastructure has allowed some of the world’s most innovative technology companies to thrive here. For that infrastructure to handle the tsunami of advanced communications and energy technologies that consumers and business are demanding and that state climate change goals require, however, the need for continued investment is pressing, according to a new report.

  • Irish coastal communities devising ways to cope with rising sea levels

    Almost two years after the winter storms of 2013-14 caused millions of euros worth of damage to Ireland’s coastline, coastal scientists are looking to help rural communities and municipalities along the Irish coast develop systems which will prevent future destruction to buildings and beach properties. Researchers say that the city of Galway had developed too close to the shoreline, leaving little room for nature to run its course. “Erosion is a natural process that only becomes a problem when we develop in areas that are soft coastline, which are naturally mobile (they erode and build depending on conditions),” says one of the researchers.
