• Cyber Gym in Israel trains cyber-defenders

    A group of IT and infrastructure companies in Israel have teamed up to launch Cyber Gym.The facility, inaugurated this month by Israel Electric Corp. (IEC), will train participants to defend against cyber attacks.When Sivan Shalom,  Israel’s Infrastructure and Energy Minister, was asked whether Israel was more concerned about a physical or a virtual attack, he said: “I think the future battle will be in cyberspace.”

  • Sea-level rise to drive flooding regardless of changes in hurricane activity

    Clamor about whether climate change will cause increasingly destructive tropical storms may be overshadowing a more unrelenting threat to coastal property — sea-level rise — according to a team of researchers. Since 1970, more than 60 percent of all economic losses — about $400 billion — occurred in the North Atlantic, even though it is one of the least active basins for hurricanes.The scientists say accelerated sea-level rise certainly will increase the flooding and property damage triggered by tropical cyclones — commonly known as hurricanes in the Atlantic and Northern Pacific — but predicting where, how often, and how powerful these storms will be when they make landfall is full of uncertainty.

  • Feds, Calif. disagree on seismic safety of U.S. tallest dam

    At 742 feet, Oroville Dam in Oroville, California is the tallest dam in the United States. It is 45-year old, and federal inspectors say it needs a comprehensive earthquake safety assessment. The California Department of Water Resources (DWR) insists that the dam, which holds 3.5 million acre-feet of water, is safe, and that such an assessment would be an “unjustified expense.” David Gutierrez, chief of California Division of Safety of Dams (DSD), says his agency will decide in January 2014 whether earthquake assessments will be made, but notes: “Oroville is not one that keeps me up at night from a seismic stability standpoint.”

  • Virtual wall to build invisible barrier for oil spills

    The outer shell of a droplet of oil on a surface has a thin skin which allows it to hold its shape like a small dome; this shell is referred to as the liquid’s surface tension. Now, researchers have developed a technique to form a virtual wall for oily liquids that will help confine them to a certain area, aiding researchers who are studying these complex molecules. This development will have future implications in the guided delivery of oil and effective blockage of oil spreading.

  • Humans threaten wetlands' ability to overcome sea level rise

    Left to themselves, coastal wetlands can resist rapid sea level rise. The reason: an intricate system of feedbacks which make wetlands remarkably good at building up soils to outpace sea level rise. Humans, however, could be sabotaging some of wetlands’ best defenses, according to results of a new study. The study examines two questions: when do wetlands reach their limit, and how are humans lowering that point?

  • Earthquake early warning? There’s an app for that

    Researchers from the University of California have unveiled a smartphone app designed to provide users an early warning of approaching earthquakes. Based on the proximity of the user to the earthquake’s epicenter, the app will provide alerts of between a few seconds and one minute before a tremor hits.

  • Better earthquake early-warning system

    Geophysicists have developed a new way of calculating the magnitude of an imminent earthquake by making better use of measurements of the compression waves produced early in the event. They say that the technique could be used to create a better early-warning system for earthquakes that could be used worldwide.

  • Y-12 security breach update: Old nun awaits sentencing while costs of new Y-12 facility not to be released until 2015

    On 28 July 2012, three senior citizens, led by an 83-year old nun, easily breached the supposedly impregnable security systems protecting the Y-12 National Security Complex at Oak Ridge, Tennessee. The three peace activists wondered the grounds of the maximum security facility for a while before being noticed by security personnel. While the three aging protesters are awaiting sentencing, the two companies — Bechtel Corporation and Babcock and Wilcox – which were responsible for designing and implementing security at Y-12, have been named as the primary construction contractors for planning and design of the new uranium processing facility (UPF) to be built at Y-12.

  • Early warning system to detect abrupt climate change impacts

    Climate change has increased concern over possible large and rapid changes in the physical climate system, which includes the Earth’s atmosphere, land surfaces, and oceans. Some of these changes could occur within a few decades or even years, leaving little time for society and ecosystems to adapt. A new report from the National Research Council states that even steady, gradual change in the physical climate system can have abrupt impacts elsewhere — in human infrastructure and ecosystems for example — if critical thresholds are crossed. The report calls for the development of an early warning system that could help society better anticipate sudden changes and emerging impacts.

  • Key to protecting Earth from asteroids: time

    Scientists say that humanity can address the threats from asteroids of any size if given enough time and notice of the asteroid’s existence and trajectory. Even an asteroid the size of the 10-kilometer-wide space rock which scientists hold responsible for the extinction of dinosaurs sixty-five million years ago, can be destroyed,  although it would take hitting the asteroid with multiple spacecrafts over a period of several decades.

  • Defending against electromagnetic-pulse attacks

    We are all familiar with the power of electromagnetic attacks from the movies: in “Ocean’s Eleven,” George Clooney’s gang disables Las Vegas’ power grid, and Keanu Reeves’ henchmen hold off the enemy robot fighters from their spaceship in the “Matrix Trilogy.” The heroes in the films succeed by sending out a very strong electromagnetic pulse, which changes the voltage in the vicinity so that regulators, switches, and circuit boards in electronic equipment go crazy. Researchers are now trying to figure out how such attacks can be detected. They have developed a measurement instrument for this purpose that is capable of determining the strength, frequency, and direction of electromagnetic attacks.

  • Digital privacy services enjoying a surge in demand

    Digital privacy services such as encrypted e-mail, secure instant messaging, and services that provide hard-to-track IP addresses are enjoying a surge in demand as individuals and businesses seek to protect information from spies and hackers in the wake of the National Security Agency’s (NSA) surveillance program revelations. These services promise security, but may also slow down computer performance. Moreover, they are not likely to deter those who are determined to hack into a particular computer network.

  • Deflecting asteroids to avoid Armageddon

    It sounds like the script for a Hollywood film: a giant meteorite from outer space heading straight for the Earth and threatening the destruction of mankind. Yet such a scenario does represent a real threat to our planet, as researchers reckon that we can expect an asteroid to collide with Earth every few hundred years. In real life, though, nobody wants to rely on a rescue plan hastily improvised at the last minute. Scientists with the European-funded research project NEOShield are working to develop concepts designed to help avert these impacts and to alter asteroids’ orbits as they race toward Earth.

  • Indian Ocean phenomenon helps in predicting extreme weather

    The Indian Ocean Dipole is the difference in sea-surface temperatures between the western and eastern part of the Indian Ocean. A better understanding of the relationship between the Indian Ocean Dipole and extreme weather events will enable farmers, industry, communities, and governments better to anticipate and prepare for droughts and increased bushfire risk, up to six months in advance of the event.

  • Developing cyber resilience to meet increasing cyberthreats

    Managing resilience for cyber systems requires metrics that reflect the relationships among system components in physical, information, cognitive, and social domains. In a paper, researchers describe a framework for understanding the concept of cyber resilience, and lay out a systematic method by which to generate resilience metrics for cyber systems.
