• 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.

  • The sobering reality of water security

    Agriculture is one of the world’s most insatiable consumers of water. Yet, it is facing growing competition for water from cities, industry, and recreation at a time when demand for food is rising, and water is expected to become increasingly scarce.

  • 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.

  • Novel technology to tackle global water challenges

    The University of Alberta will unveil new technologies its researchers and students will use to replace inadequate water purification and monitoring equipment in remote communities in Canada and India.

  • 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.

  • System to vaporize asteroids that threaten Earth

    As an asteroid roughly half as large as a football field — and with energy equal to a large hydrogen bomb – flew by Earth on Friday, two California scientists unveiled their proposal for a system that could eliminate a threat of this size in an hour. The same system could destroy asteroids ten times larger than the one known as 2012 DA14 in about a year, with evaporation starting at a distance as far away as the Sun.

  • The ground is key to cleaner environment, water

    While many people recognize that clean water and air are signs of a healthy ecosystem, most do not realize that a critical part of the environment is right beneath their feet. The ground plays an important role in maintaining a clean environment by serving as a natural water filtration and purification system.

  • Quantum cryptography to secure electric grid

    Novel methods for controlling the electric grid are needed to accommodate new energy sources such as renewables whose availability can fluctuate on short time scales. This requires transmission of data to and from control centers; but for grid-control use, data must be both trustworthy and delivered without delays. The Los Alamos National Laboratory quantum cryptography team successfully completed the first-ever demonstration of securing control data for electric grids using quantum cryptography.

  • Infrastructure renewal in regional Australia

    New research in Australia calls for the establishment of a new national organization to tackle the shortfall in infrastructure investment and boost the regions’ capacity to contribute to national economic growth. Expert say the new organization, to be called Local Infrastructure Australia, would be the most effective way of overcoming the backlog in local government infrastructure investment now estimated at between $12 and $15.5 billion.

  • Sewage lagoons remove most pharmaceuticals from wastewater

    Despite these advances made under the Clean Water Act, sewage remains a major source of pharmaceuticals and personal care products (PPCPs) and naturally occurring hormones found in the environment. New research shows the effectiveness of rural lagoon systems at removing these compounds from wastewater.

  • Lessons from the 2010-11 Australia floods

    New research has come up with ways quickly to assess flood damage to houses while also showing most people did not intend to make changes to reduce their vulnerability after the 2010-11 Australia floods. Two separate reports show how lessons learned from households affected by the 2010-11 Australian floods can minimize damage under current and future climates.

  • Sediment carried by 2011 Mississippi flood shored up Louisiana’s wetlands

    The spring 2011 flood on the Mississippi was among the largest floods ever, the river swelling over its banks and wreaking destruction in the surrounding areas. A new study also shows, however, that the floods reaped environmental benefits — transporting and laying down new sediment in portions of the Delta — that may help maintain the area’s wetlands.

  • Obama to issue cybersecurity executive order today

    President Barack Obama is expected to issue an executive order tomorrow to dealing protecting U.S. critical infrastructure from cyberattacks. The order will be issues one day after the president’s State of the Union address. The order will establish a critical infrastructure council which will be run by DHS and will include members of the Departments of Defense, Justice, and Commerce as well as the National Intelligence Office. The council will be tasked with formulating new regulations for federal agencies, or broadening regulations  already in place. The regulations will most likely include the sharing of data between private corporations and the federal government.

  • The Middle East rapidly losing fresh water

    A new study using data from a pair of gravity-measuring NASA satellites finds that large parts of the arid Middle East region lost freshwater reserves rapidly during the past decade. Scientists found during a seven-year period beginning in 2003 that parts of Turkey, Syria, Iraq, and Iran along the Tigris and Euphrates river basins lost 117 million acre feet (144 cubic kilometers) of total stored freshwater. That is almost the amount of water in the Dead Sea. The researchers attribute about 60 percent of the loss to pumping of groundwater from underground reservoirs.

  • Infrastructure sees drop in funding last year

    Infrastructure investments in roads, bridges, and power stations have dropped significantly in 2012 as banks struggled to offer long-term debt and governments targeted cost savings. There were hopes that infrastructure spending would boost the world economy in 2012, but funding fell from $159 billion worldwide in 2011 to $99 billion.
