• How building codes save homes from cyclones, and how they don’t

    During Queensland’s preparations for Severe Tropical Cyclone Ita, Queensland Premier Campbell Newman advised residents who lived in older houses (those built before 1985) to evacuate their homes as they were not likely to stand up to the storm’s destructive winds. That was the year that building regulations changed to require new houses in cyclone-prone areas to be able to withstand higher winds. But how were these regulations determined, what do they mean for modern homes, and why do regulators always seem to wait until after a severe storm before updating the codes?

  • West Point wins Cyber Defense Exercise, launches Army Cyber Institute

    The U.S. Military Academy at West Point has won the annual Cyber Defense Exercise (CDX) which brought together senior cadets from the five service academies for a 4-day battle to test their cybersecurity skills against the National Security Agency’s (NSA) top information assurance professionals. West Point’s win comes just as the academy announced plans for its Army Cyber Institute(ACI), intended to develop elite cyber troops for the Pentagon.

  • How the Heartbleed bug reveals a flaw in online security

    The Heartbleed bug – which infects an extremely widespread piece of software called OpenSSL  — has potentially exposed the personal and financial data of millions of people stored online has also exposed a hole in the way some security software is developed and used. The Heartbleed bug represents a massive failure of risk analysis. OpenSSL’s design prioritizes performance over security, which probably no longer makes sense. But the bigger failure in risk analysis lies with the organizations which use OpenSSL and other software like it. A huge array of businesses, including very large IT businesses with the resources to act, did not take any steps in advance to mitigate the losses. They could have chosen to fund a replacement using more secure technologies, and they could have chosen to fund better auditing and testing of OpenSSL so that bugs such as this are caught before deployment. They didn’t do either, so they — and now we — wear the consequences, which likely far exceed the costs of mitigation.

  • California implements earthquakes’ lessons

    In California, government engineers study structures that did not survive the earthquake, with plans to make improvements to building codes. The most important code changes tend to occur because earthquakes uncover weaknesses in contemporary construction standards.”Every time the earth shakes there’s something a little different about it,” says one official.

  • Feds struggle to plug power grid security holes

    Many of the current vulnerabilities in the power grid are attributable to newly adopted smart-grid technology, which allows operators to transmit energy from a diverse pool of resources. Smart-grid technology relies on devices in remote locations which constantly communicate with substations, those access points can be compromised by hackers.

  • A grid of the right size could reduce blackout risk

    Scientists argue that for every animal there is an optimal size — one which allows it to make best use of its environment and the physical laws that govern its activities, whether hiding, hunting, hoofing, or hibernating. Now, researchers are asking whether there is a “right” size for another type of huge beast: the U.S. power grid. The researchers believe that smaller grids would reduce the likelihood of severe outages, such as the 2003 Northeast blackout that cut power to fifty million people in the United States and Canada for up to two days.

  • Bangladesh tops list of countries at risk from sea level rise

    Scientists say that see levels may rise by up to the feet by 2100.The implications of this would have drastic consequences for nearly all coastal nations, but the consensus is that Bangladesh will be the hardest hit by the change. Leading Bangladeshis say that since Bangladesh produces less than 0.3 percent of the emissions driving climate change, it would unjust for Bangladesh to rely on its own meager resources to solve this problem. One solution they offer: fifty million Bangladeshis (out of a population of 163 million) should be allowed to move to and resettle in the countries which produce the bulk of greenhouse gasses.

  • Coalition sounds alarm about possible global EMP disaster

    A coalition that includes former speaker of the House Newt Gingrich and former CIA director James Woolsey has issued a terse warning regarding apocalyptic effects that could result from a mass EMP (electromagnetic pulse) disaster or attack. Members of the coalition “are convinced that our fragile electrical grid could be wiped out at any moment” from bursts of electrical energy caused by anything from a nuclear explosion to a solar flare from the sun, leading to chaos on a global scale.

  • Capabilities-based – rather than actuarial -- risk analysis would make businesses safer

    Many businesses and organizations, when applying cost-benefit analysis and a risk-management analysis to measure cyber risk, are relying on the assumption that the likelihood of a future attack depends heavily on how many attacks have occurred in the past. Since there has yet to be a full-scale attack on critical infrastructure in the United States, it is simple to conclude that the risk of a cyberattack on critical infrastructure is low, therefore justifying low investment in additional security initiatives. An actuarial risk analysis may conclude that there is little likelihood of such as attack occurring, but a capabilities-based risk analysis recognizes that since adversaries are capable of such an attack, it is in an organization’s best interest to secure against it.

  • Sandia to help cities be better prepared for, emerge stronger from, disasters

    Sandia National Laboratories says it will bring its experience solving problems with practical engineering and modeling complex systems to cities around the world under a new agreement to support the 100 Resilient Cities Centennial Challenge, pioneered by the Rockefeller Foundation. The challenge, which will help thirty-three cities in its first year, seeks to make communities more resilient by being better prepared to withstand natural or manmade disasters, recover more quickly, and emerge stronger.

  • Roadmap outlines R&D path to reduce storm impacts

    A new measurement science research and development (R&D) roadmap, prepared for the National Institute of Standards and Technology (NIST) over the past two years by a private-sector group of hazard mitigation experts, provides a broad strategic approach and R&D objectives to reduce impacts from windstorms and coastal inundations, including storm surge during hurricanes and tsunamis.

  • Friday L.A. tremor harbinger of quake worse than the Big One

    Seismologists warn that a bigger earthquake along the Puente Hills fault, which produced the 5.1 magnitude tremor in Los Angeles last Friday, could cause more damage to the region than the anticipated “Big One” from the San Andreas Fault located on the outskirts of metropolitan Southern California. A 7.5-magnitude earthquake along the Puente Hills fault could kill 3,000 to 18,000 people and cause up to $250 billion in damages, leaving up to 750,000 people homeless. In contrast, an 8-magnitude earthquake along the San Andreas Fault would result in about 1,800 deaths.

  • Using more wood for construction will reduce reliance on fossil fuels

    A new study has found that using more wood and less steel and concrete in building and bridge construction would substantially reduce global carbon dioxide emissions and fossil fuel consumption. Despite an established forest conservation theory holding that tree harvesting should be strictly minimized to prevent the loss of biodiversity and to maintain carbon storage capacity, the study shows that sustainable management of wood resources can achieve both goals while also reducing fossil fuel burning.

  • Delaware launches cyber initiative

    Delaware is joining the number of states that have decided to invest in a statewide cybersecurity workforce to combat the growing threat of cyberattacks directed at both private and public institutions.Delaware hopes its cyber initiative will accelerate current efforts to develop a stronger cyber workforce. The Delaware Cyber Initiative proposes $3 million for a collaborative learning and research network in the form of part research lab, part business park, dedicated to cyber innovation.

  • Quantum mechanics may lead to ultra-secure Internet

    In 1935 Einstein and researchers highlighted a “spooky” theory in quantum mechanics, which is the strange way entangled particles stay connected even when separated by large distances. In the 1990s, scientists realized you can securely transmit a message through encrypting and using a shared key generated by Einstein’s strange entanglement to decode the message from the sender and receiver. Using the quantum key meant the message was completely secure from interception during transmission.
