• Bomb Cyclones and Breadbaskets: How Climate, Food, and Political Unrest Intersect

    As climate change continues to increase both the frequency and magnitude of extreme weather events, extreme consequences can emerge across and downstream from these supply chains. The Intergovernmental Panel on Climate Change’s latest report discusses at length the challenges that increasing global population and climatic volatility pose to food and water scarcity—and, consequently, to social and economic systems. As a result, weather and climate forecasting— coupled with the computer-aided modeling of economic and political resilience to such events—could help improve predictions of political flashpoints greatly at a time of unprecedented environmental change.

  • Security in a Heartbeat

    Sandia National Laboratories is collaborating with Aquila, a New Mexico small business, to test and develop a biometric security system based on the human heartbeat. Aquila and Sandia will jointly assess the form the wearable may take, such as a wristband or chest strap. It would be an alternative to such things as fingerprints and eye scans when those access-control methods might be limited, such as in a laboratory where gloves or eye protection may be necessary.

  • Past California Wildfire Activity Suggests Climate Change Will Worsen Future Fires

    In the wake of recent wildfires that have ravaged northern and central California, a new study finds that the severity of fire activity in the Sierra Nevada region has been sensitive to changes in climate over the past 1,400 years. The findings suggest that future climate change is likely to drive increased fire activity in the Sierras.

  • New Institute to Lead Government, Industry Effort to Make 5G More Secure

    5G wireless technology promises to deliver a technology revolution in wireless communication. Already, wireless carriers and equipment manufacturers are incorporating 5G capabilities in their devices and working to construct national 5G networks. As the 5G revolution moves forward, a national challenge will emerge to develop and validate 5G security protocols and data protection technologies. To respond to this challenge, Idaho National Laboratory (INL) has established the INL Wireless Security Institute to lead and coordinate government, academic, and private industry research efforts fostering more secure and reliable 5G wireless technology.

  • National Security Chip Plant Gets an Upgrade

    Sandia National Laboratories has completed phase one of an anticipated three-year upgrade at its plant responsible for making integrated circuits. The upgrade will align Sandia with industry, but the Lab notes that the decision to upgrade was driven by the Lab’s national security mission. Six years of planning ensured the conversion would not affect production of components needed for national defense. Chips produced at Sandia can be found in the nation’s nuclear stockpile.

  • An Umbrella to Combat Warming

    By Anna Gibbs

    Research examines the possibility of spraying tiny particles into the stratosphere to block the sun a bit and cool the planet. Shielding the Earth with a mist of tiny particles sounds like the stuff of sci-fi movies, but since it was first proposed in the 1950s the idea has gained traction among scientists around the world to shield us not from extraterrestrials, as Hollywood might have it, but from the sun. Known as solar geoengineering, the concept is to send planes into the stratosphere — 6 to 31 miles above the Earth — to spray particles that can reflect sunlight back into space and cool the planet.

  • Climate Change Could Cause Drought in Wheat-Growing Areas

    In a new study, researchers found that unless steps are taken to mitigate climate change, up to 60 percent of current wheat-growing areas worldwide could see simultaneous, severe and prolonged droughts by the end of the century. Wheat is the world’s largest rain-fed crop in terms of harvested area and supplies about 20 percent of all calories consumed by humans.

  • For Scientific Integrity in Government, Fix Political Appointments Process

    The list of scandals featuring senior U.S. officials who subsumed scientific integrity to their political or personal interests numbers 60 entries in a new report from a bipartisan task force that traced practices under the past three presidents. The examples range from downplaying the connections between climate change and carbon emissions under George W. Bush to understating the risks of fracking on drinking water under Barack Obama, and on to retaliation against economists, biologists and climate scientists under Donald Trump. While the vast majority of the incidents listed occurred under the Trump administration, the task force warns that the pattern represents a kind of continuum: that abuses of the past weakened the guardrails of democracy to allow what’s happening today, and that the trend could escalate in future administrations unless Congress takes steps to strengthen safeguards. And at the root of each instance are the individuals who committed the abuses, whether the president or his political appointees.

  • India-Pakistan Nuclear War Could Kill Millions, Lead to Global Starvation

    A nuclear war between India and Pakistan could, over the span of less than a week, kill 50-125 million people—more than the death toll during all six years of World War II, according to new research. The researchers calculated that an India-Pakistan war could inject as much as 80 billion pounds of thick, black smoke into Earth’s atmosphere. That smoke would block sunlight from reaching the ground, driving temperatures around the world down by an average of between 3.5-9 degrees Fahrenheit for several years. Worldwide food shortages would likely come soon after. Today, India and Pakistan each have about 150 nuclear warheads at their disposal, and that number is expected to climb to more than 200 by 2025.

  • How to Dismantle a Nuclear Bomb: Team Successfully Tests New Method for Verification of Weapons Reduction

    By Peter Dizikes

    How do weapons inspectors verify that a nuclear bomb has been dismantled? An unsettling answer is: They don’t, for the most part. When countries sign arms reduction pacts, they do not typically grant inspectors complete access to their nuclear technologies, for fear of giving away military secrets. Now MIT researchers have successfully tested a new high-tech method that could help inspectors verify the destruction of nuclear weapons. The method uses neutron beams to establish certain facts about the warheads in question — and, crucially, uses an isotopic filter that physically encrypts the information in the measured data.

  • New $100M Innovation Hub for a Secure Water Future

    The National Alliance for Water Innovation (NAWI), which is led by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), has been awarded a five-year, $100-million Energy-Water Desalination Hub by DOE (pending appropriations) to address water security issues in the United States.

  • What’s at Stake in Trump’s War on Huawei: Control of the Global Computer-Chip Industry

    By Clinton Fernandes

    Silicon Valley may now be more popularly associated with software companies such as Google and Facebook but it takes its name from the material most used to make semiconductors. Semiconductors – or computer chips – power everything from mobile phones to military systems. The semiconductor industry sits at the center of the modern world. This point is key to appreciating what’s going on in the US government’s battle with Chinese technology giant Huawei.

  • Containing a Nuclear Accident with Ground-up Minerals

    Researchers at Sandia National Laboratories are developing a promising new way to prevent the spread of radioactive contamination and contain the hot molten mass that develops within a nuclear reactor during a catastrophic accident. A team of scientists discovered and patented a process for injecting sand-like minerals into the core of a nuclear reactor during an accident to contain and slow down the progression of a meltdown.

  • Designing the Coastal City of the Future

    Boston is situated along the Gulf of Maine, which is warming faster than 99 percent of the ocean due, in part, to changing sea patterns from melting ice in Greenland and the Arctic Ocean. Coupled with increased heat and precipitation, the rising sea level is threatening the low-lying city, much of which was built on landfill over the past 300 years along a 50-square-mile harbor. To save the 685,000-person city, the local government is calling on architects to help implement one of the most ambitious municipal resiliency plans in the United States: Climate Ready Boston. Launched in 2016 by Mayor Martin J. Walsh, Climate Ready Boston is an initiative to prepare the city for the long-term impacts of climate change.

  • Arctic Ice Is Melting Faster Than Expected. These Scientists Have a Radical Idea to Save It.

    glaciers, polar land, and sea ice are rapidly melting, much faster than many scientists expected, as the Intergovernmental Panel on Climate Change’s (IPCC) report on oceans and the cryosphere released Wednesday reiterated. During a five-day heat wave this summer, Greenland lost more than 60 billion tons of ice, including the biggest loss in a 24-hour period since record-keeping began. Recent projections warn that Arctic summers could be nearly ice-free in 10 to 40 years. These grim warnings have prompted more researchers to apply technological solutions that intervene in the earth’s climate systems to slow the impacts of global warming, also known as “geoengineering.”
