• Exploring Arctic clues to secure future

    The Arctic is undergoing rapid change, with sea ice melting and temperatures rising at a faster pace than anywhere else in the world. Its changing environment affects global security, politics, the economy and the climate. Understanding these changes is crucial for shaping and safeguarding U.S. security in the future, Sandia scientists say.

  • Next California's Big One could kill hundreds, cause $100 billion in losses, trap 20,000 in elevators

    What will happen when the next big earthquake hits northern California? Researchers say that if a tremor similar in magnitude to the 1906 San Francisco earthquake were to hit today, it could kill 800 people, cause more than $100 billion in economic losses from the shaking and subsequent fires, and trap roughly 20,000 people in elevators across northern California.

  • California suffering: Severe climate future for the state

    California is headed for a future of precipitation extremes. Researchers say that the state will experience a much greater number of extremely wet and extremely dry weather seasons — especially wet — by the end of the century. The authors also predict that there will be a major increase in the likelihood of severe flooding events, and that there will be many more quick changes from one weather extreme to the other.

  • Lawmakers question Pruitt’s proposal to limit EPA’s use of science

    The EPA has announced new policy-making rules which, critics say, are aimed to reduce the role of science in the agency’s decisions. EPA’s proposal would limit the scientific information used in rulemaking, allow the agency to ignore scientific studies where the underlying data has not been made public, and force the agency to only use scientific data that can be reproduced. Lawmakers yesterday sent a detailed letter to EPA administrator Scott Pruitt, requesting more information on his proposal.

  • Making combat vehicles lighter

    The military spends several billion dollars each year on fuel consumption, which could be reduced by lessening the weight of ships, aircraft, ground vehicles, and cargo. Researchers have developed and successfully tested a novel process — called Friction Stir Dovetailing — that joins thick plates of aluminum to steel. The new process will be used to make lighter-weight military vehicles that are more agile and fuel efficient.

  • Rapid rise in mass school shootings in U.S.

    The Columbine High School mass shooting occurred on 20 April 1999. More people have died or been injured in mass school shootings in the United States in the past eighteen years than in the entire twentieth century. During the twentieth century, mass school shootings killed 55 people. Since the start of the twenty-first century there have already been 13 incidents of mass school shooting, in which 66 people have been killed.

  • Understanding explosive sensitivity with molecule design

    Explosives have an inherent problem - they should be perfectly safe for handling and storage but detonate reliably on demand. Using computer modeling and a novel molecule design technique, scientists have replaced one “arm” of an explosive molecule to help unravel the first steps in the detonation process and better understand its sensitivity — how easily it begins a violent reaction.

  • The 100th meridian, where the Great Plains begin, shifting eastward

    In 1878, the American geologist and explorer John Wesley Powell drew an invisible line in the dirt—the 100th meridian west, the longitude he identified as the boundary between the humid eastern United States and the arid Western plains. Now, 140 years later, scientists that the line appears to be slowly moving eastward, due to climate change. They say it will almost certainly continue shifting in coming decades, expanding the arid climate of the western plains into what we think of as the Midwest. The implications for farming and other pursuits could be huge.

  • Developing secure mobile apps

    Mobile devices such as smartphones and tablets and the applications (apps) we load onto them have become indispensable to our daily lives—both personal and professional. However, mobile apps are susceptible to malware, ransomware, spyware, coding flaws and other attacks that could compromise personal data stored on the device. Apps also can be used to gain access to sensitive enterprise resources.

     

  • New technology removes phosphorus from manure

    Excess phosphorus, primarily in runoff from land application of manure, accounts for about 66 percent of impaired conditions of U.S. rivers and has created large areas of eutrophication — dead zones — in the Chesapeake Bay and the Gulf of Mexico, where aquatic life cannot survive. Nutrient pollution is one of America’s most widespread, costly and challenging environmental problems. Researchers have developed an innovation that could have a huge impact on water quality problems in the United States, a system capable of removing almost all phosphorus from stored livestock manure.

  • First annual Electronics Resurgence Initiative summit announced

    The microelectronics community is facing an array of long foreseen obstacles to Moore’s Law, the transistor scaling that has allowed for fifty years of rapid progress in electronics. Current economic, geopolitical, and physics-based complications make the future of the electronics industry uniquely interesting at this moment. The U.S. electronics community will convene in late July to inaugurate a five-year, $1.5B effort to create transformative advances in electronics.

  • DHS S&T to demonstrate cyber technologies at RSA

    DHS S&T will exhibit and demonstrate thirteen mature cybersecurity technology solutions that are ready for pilot deployment and commercialization at the RSA 2018 cybersecurity conference, 16-19 April, in San Francisco.

  • Carbon taxes could make significant dent in climate change, study finds

    Putting a price on carbon, in the form of a fee or tax on the use of fossil fuels, coupled with returning the generated revenue to the public in one form or another, can be an effective way to curb emissions of greenhouse gases. That’s one of the conclusions of an extensive analysis of several versions of such proposals, carried out by researchers at MIT and the National Renewable Energy Laboratory (NREL).

  • Scientists call for more science in forensic science

    With forensic science facing mounting scrutiny as it plays an increasingly prominent role in the administration of justice, scientists are calling on the scientific community at large to advocate for increased research and financial support of forensic science as well as the introduction of empirical testing requirements to ensure the validity of outcomes.

  • Mimicking the human immune system to detect outbreaks faster

    Our immune systems are made up of billions of white blood cells searching for signs of infections and foreign invaders, ready to raise the alarm. Sandia National Laboratories computer scientists have been working to improve the U.S. biosurveillance system that alerts authorities to disease outbreaks by mimicking the human immune system.
