• 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • Northeast U.S. digs out after deadly snowstorm

    About 250,000 homes and businesses in northeast United States remain remained without power this morning as a blizzard dumped more than three feet of snow on north-mid-Atlantic and New England states, and parts of Canada. The death toll was at fifteen. Utilities in New England said the storm could leave some customers in the dark at least until Tuesday. About 650,000 lost power in eight states at the height of the storm.

  • Tiny organisms in oceans can save islands from rising sea levels: study

    Warming climate is causing sea levels to rise, posing a special threat to low-lying island nations. The government of the Maldive Islands, an island nation in the Indian Ocean consisting of a chain of twenty-six atolls, has begun exploring the possibility of purchasing land in Africa to relocate the entire population – about 330,000 – once rising sea water begin to swallow the small atolls. Scientists found out, though, that the warming temperature of the seas is causing tiny single-cell organisms to are spreading rapidly through the world’s oceans, where they just might be able to mitigate the consequences of climate change.

  • New internally cured concrete increases bridge life span

    Concrete is normally made by mixing portland cement with water, sand, and stone. In the curing or hardening process, water helps the concrete mixture gain strength by reacting with the cement. Traditionally, curing is promoted by adding water on top of the bridge deck surface. The new technology for internal curing provides additional water pockets inside the concrete, enhancing the reaction between the cement and water, which adds to strength and durability. This new technology is enabling Indiana to improve bridges in the state with a new “internally cured” high-performance concrete.
