• Volcanic aerosols, not pollutants, slowed recent Earth warming

    Researchers looking for clues about why Earth did not warm as much as scientists expected between 2000 and 2010 now thinks the culprits are hiding in plain sight — dozens of volcanoes spewing sulfur dioxide.

  • RFI for cybersecurity framework for critical infrastructure

    In his 12 February 2013 Executive Order, President Obama called for the development of a Cybersecurity Framework to reduce cyber risks to critical infrastructure such as power plants and financial, transportation, and communications systems. The National Institute of Standards and Technology (NIST) the other day issued a Request for Information (RFI) in the Federal Register as its first step in the process to developing that framework.

  • No gloom-and-doom: science does not back global tipping point view

    A group of international ecological scientists have rejected a doomsday-like scenario of sudden, irreversible change to the Earth’s ecology. The scientists argue that global-scale ecological tipping points are unlikely and that ecological change over large areas seem to follow a more gradual, smooth pattern.

  • New power engineering curriculum to help U.S. security, economy

    Nearly 40 percent of all energy consumed in the United States is first converted to electricity, with that figure expected to rise to as much as 70 percent in the future. Increasing the pipeline of graduates in electric power and energy has implications for both the country’s place in the global market and national defense. The more expertise there is at home, the less the United States will have to import talent and energy resources from overseas. An Office of Naval Research (ONR)-supported project is bringing sweeping changes to electric power and energy education at universities throughout the country, establishing first-time programs at some schools and bringing new courses and labs to others.

  • Report details history, earlier versions of Stuxnet

    In 2010, Symantec reported on a new and highly sophisticated worm called Stuxnet. This worm became known as the first computer software threat which was used as a cyber-weapon. In a new report, Symantec says that clues in the code pointed to other versions of the worm which could potentially perform different actions leaving an open question about Stuxnet and how it came to be.

  • Weather extremes caused by giant waves trapped in the atmosphere

    The world has suffered from severe regional weather extremes in recent years, such as the heat wave in the United States in 2011 or the one in Russia 2010, coinciding with the unprecedented Pakistan flood. Behind these devastating individual events there is a common physical cause, propose scientists in a new study. The study suggests that man-made climate change repeatedly disturbs the patterns of atmospheric flow around the globe’s Northern hemisphere through a subtle resonance mechanism.

  • Russian fireball largest ever detected by nuke monitoring organization

    Infrasound has been used as part of the Comprehensive Nuclear Test Ban Treaty Organization’s (CTBTO) monitoring tools to detect atomic blasts since April 2001 when the first station came online in Germany. Infrasonic waves from the meteor that broke up over Russia’s Ural Mountains last week were the largest ever recorded by the CTBTO’s International Monitoring System.

  • Climate change as a national security issue

    In a new report, Harvard researcher is pointing toward a new reason to worry about the effects of climate change — national security. During the next decade, the report concludes, climate change could have wide-reaching effects on everything from food, water, and energy supplies to critical infrastructure and economic security. “The imminent increase in extreme events will affect water availability, energy use, food distribution, and critical infrastructure — all elements of both domestic and international security,” the report’s author says.

  • Self-healing protective coating for concrete

    Scientists are reporting development of what they describe as the first self-healing protective coating for cracks in concrete, the world’s most widely used building material. The coating is inexpensive and environmentally friendly.

  • U.S. responds to China’s cyberattacks with anti-theft trade strategy

    The Obama administration yesterday (Wednesday) unveiled the details of a broad strategy to counter the systemic theft by Chinese government agencies of U.S. trade and technology and trade secrets. The administration’s plan calls for new diplomatic push to discourage intellectual property theft abroad and better coordination at home to help U.S. companies protect themselves.

  • Earthquake catastrophes and fatalities to rise in 21st century

    Predicted population increases in this century can be expected to translate into more people dying from earthquakes. There will be more individual earthquakes with very large death tolls as well as more people dying during earthquakes than ever before, according to a new study.

  • U.S. weighing retaliatory measures against China for hacking campaign

    As incontrovertible evidence emerged for the role of Chinese government in initiating and orchestrating the massive, sustained Chinese hacking campaign against U.S. private companies, government agencies, and critical infrastructure assets, the administration has intensified discussions of retaliatory measures the United States may take against China.

  • Spotting potential targets of nefarious e-mail attacks

    The weakest link in many computer networks is a gullible human. With that in mind, computer science researchers want to figure out how to recognize potential targets of nefarious e-mails and put them on their guard.

  • Chinese government orchestrates cyberattacks on U.S.: experts

    For more than a decade now, China has engaged in a sustained, systemic, and comprehensive campaign of cyber attacks against the United States. The Chinese government has enlisted China’s sprawling military and civilian intelligence services, with their armies of cyber-specialists, in a cyber-campaign aiming to achieve three goals: steal Western industrial secrets and give them to Chinese companies, so these companies could compete and weaken their Western rivals; hasten China’s march toward regional, then global, economic hegemony; achieve deep penetration of U.S. critical infrastructure in order to gain the ability to disrupt and manipulate American critical infrastructure – and paralyze it during times of crisis and conflict. A detailed 60-page study, to be released today , offers, for the first time, proof that the most sophisticated Chinese hacker groups, groups conducting the most threatening attacks on the United States, are affiliated with the headquarters of China’s military intelligence lead unit — PLA Unit 61398.

  • Russia meteor a “once every 100 years” event

    The meteor which disintegrated in the skies over Chelyabinsk, Russia, early Friday morning entered the atmosphere at about 40,000 mph (18 kilometers per second). The energy released by the impact was in the hundreds of kilotons.The meteor is the largest reported since 1908, when a meteor hit Tunguska, Siberia.
