• 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.

  • Chinese set to buy yet another U.S. taxpayer-backed hi-tech firm

    Lawmakers yesterday expressed their concerns about the likelihood that U.S. taxpayer dollars could end up bolstering the Chinese economy. The lawmakers reacted to reports that a Chinese firm, Zhejiang Geely Holding Group, is leading the list of companies bidding for a majority stake in government-backed Fisker Automotive, and that the only serious rival of that Chinese company is a Chinese auto maker. Fisker’s main battery supplier — U.S. government-backed A123 Systems – has already been acquired by a separate Chinese firm.

  • Improving detection of, responses to biological warfare

    Biological warfare agents pose more than a hypothetical threat to U.S. soldiers. Troops operate in hostile areas where they could come under attack from adversaries wielding bio-agents like anthrax and toxins. The first step in reacting to any such attack is knowing that it occurred. Quickly and accurately identifying the presence of airborne antigens can be difficult given their complexity, the presence of numerous similar microorganisms in the environment, and the fact that even minute quantities of a threat agent can cause infection. Researches seek to advance sensitivity and durability of antibody-based biosensors better to protect soldiers.

  • 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.

  • High school students to compete in DOE National Science Bowl

    The U.S. Department of Energy (DOE) created the National Science Bowl in 1991 to encourage students to excel in math and science and pursue careers in related fields. More than 200,000 students have participated in the National Science Bowl in the twenty-three years since its inception. Students from Los Alamos High School will represent New Mexico at the Department of Energy’s National Science Bowl in April.

  • Water managers can now consult new U.S. water evaporation maps

    The amount of water available for people and ecosystems is the amount of annual precipitation — that is, snow or rain — minus the amount of annual evapotranspiration.  Evapotranspiration itself is the amount of water lost to the atmosphere from the ground surface. Scientists map the long-term U.S. evapotranspiration rates for the first time.

  • Prof. strips, stabs stuffed animal to teach quantum mechanics

    Students who showed up for Monday’s quantum physics class of Professor Emlyn Hughes, a Columbia University physics professor, found out they were in for a new approach to teaching the week’s topic.

    As the students entered the classroom, they were greeted with the tune of Lil Wayne’s “Drop It Like It’s Hot.” As the students were taking their seats, Hughes removed his clothes, then changed into a black T-shirt and pants. He then sat down and hugged his knees in a fetal position before airing video footage of the 9/11 2001 terror attacks, and videos of aerial bombardments from the Second World War.

  • Diatribes, rants in “Comments” section tarnish allure of science online

    More and more digital publications, including science publications, have added a “Comments” feature to their Web sites, allowing readers to post their comments on the articles they read. This democratization of commentary, however, has been accompanied by increasingly nasty back-and-forth exchanges among readers, especially on sites where the comments are not moderated. A new study shows that in the realm of online science news, this steady diet of diatribes, screeds, and rants is taking a toll on the public perception of science and technology.

  • Harvard president issues a clarion call for science

    Harvard President Drew Faust, addressingthe annual meeting of the American Association for the Advancement of Science (AAAS), called for members of the scientific community to “raise our voices” in an effort to prevent the U.S. Congress from becoming “an American Association for the Retreat of Science.” Urging widespread efforts to prevent U.S. cuts in funds for sustained research, Faust said: “We must secure the federal research support critical to the future of our nation and of the world.”

  • 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.

  • The costly wild-weather consequences of climate change

    Throughout 2012, the United States was battered by severe weather events such as hurricanes and droughts that affected both pocketbooks and livelihoods. Research suggests that in the coming years, U.S. five-day forecasts will show greater numbers of extreme weather events, a trend linked to human-driven climate change.

  • 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.

  • Making communities more resilient to climate-induced weather disasters

    Mounting scientific evidence indicates climate change will lead to more frequent and intense extreme weather that affects larger areas and lasts longer. We can reduce the risk of weather-related disasters, however, with a variety of measures. Experts say that a good strategy should include a variety of actions such as communicating risk and transferring it through vehicles such as insurance, taking a multi-hazard management approach, linking local and global management, and taking an iterative approach as opposed to starting with a master plan.

  • Toxic legacy of lead pollution persists despite regulatory efforts, modest gains

    Efforts to reduce lead pollution have paid off in many ways, yet the problem persists and will probably continue to affect the health of people and animals well into the future. The good news, he said, is that atmospheric lead concentrations in the United States have fallen by 89 percent in the past three decades.The bad news is that blood lead levels are still about 100 times higher than the natural background level, and there is no known threshold for lead toxicity. In other words, even tiny amounts of lead in the body can be harmful.
