• Chicago becomes first city to launch Array of Things, an innovative urban sensing project

    This week in Chicago, the Array of Things team begins the first phase of the groundbreaking urban sensing project, installing the first of an eventual 500 nodes on city streets. By measuring data on air quality, climate, traffic, and other urban features, these pilot nodes kick off an innovative partnership among different organizations aiming better to understand, serve, and improve cities.

  • Assessing climate change vulnerability in urban America

    Impacts of climate change – rising sea levels, heat waves, rising rates of diseases caused by ticks, fleas, and mosquitoes, and many more — will affect cities across the country. One of the first efforts systematically to assess how cities are preparing for climate change shows that city planners have yet fully to assess their vulnerability to climate change, leaving serious risks unaddressed. Most city planners have yet to prepare for climate-related risks and the consequences.

  • Pace of Earth’s warming “unprecedented in 1,000 years”: NASA

    The warming of the planet is proceeding at a pace not experienced within the past 1,000 years, making it “very unlikely” to keep warming to 1.5 degrees Celsius – the goal agreed by nations at the Paris climate summit last December. Recent research found that continuing current levels of carbon dioxide emissions for just five more years will eliminate any chance of restraining temperatures to a 1.5C increase and avoid runaway climate change.

  • Large-scale metamaterials could earthquake-proof buildings in tremor-prone regions

    Metamaterials – artificial structures that exhibit extraordinary vibrational properties – could come to the rescue of regions threatened by earthquakes, according to new research. The study, performed by researchers in Europe and involving detailed computer simulations, shows that large-scale metamaterials can attenuate the energy and amplitude of harmful low-frequency vibrations associated with seismic shocks.

  • Nuclear forensics summer program trains students for a future in nuclear security

    A sure sign of summer is the return of interns to the Lawrence Livermore campus. Students interact with premier researchers and access equipment and facilities not available anywhere else, while scientists lay groundwork for advancing their fields. LLNL runs an eight-week summer internship for students interested in nuclear science and its range of specialties — nuclear forensics, environmental radiochemistry, nuclear physics, and beyond. Together, these disciplines support the laboratory’s nuclear security mission through analysis of nuclear processes and properties.

  • French schools to hold security drills, including mock terrorist attacks

    As part of the French government’s bolstering of security measures in the wake of a series of terrorist attacks, French schools, beginning with the new school year, will now conduct three security drills a year – including at least one drill in which a mock assailants enter the school building.

  • Wider temperature tolerance is based on ion-pair-coordinated polymers

    A new class of fuel cells based on a newly discovered polymer-based material could bridge the gap between the operating temperature ranges of two existing types of polymer fuel cells, a breakthrough with the potential to accelerate the commercialization of low-cost fuel cells for automotive and stationary applications.

  • Rising seas threaten 1.9 million U.S. homes with current value of $882 billion

    Typically when we talk about “underwater” homes, we are referring to negative equity. But there is a more literal way a home can be underwater: Rising sea levels, and the flooding likely to come with them, could inundate millions of U.S. homes worth hundreds of billions of dollars. If sea levels rise as much as climate scientists predict by the year 2100, almost 300 U.S. cities would lose at least half their homes, and 36 U.S. cities would be completely lost. The total combined current value of all homes at risk of being underwater with a 6-feet rise in sea levels is $882 billion.

  • Presidential candidates may be psychopaths – but this is not necessarily a bad thing

    Oxford University’s Dr. Kevin Dutton has spent much of his career looking at psychopaths and researching psychopathic traits, identifying those which can be of benefit and those which can lead to incarceration. He contends that being a psychopath is not an all-or-nothing affair. Instead, psychopathy is on a spectrum along which each of us has our place. In a new study, Dutton finds that Donald Trump ranks above Adolf Hitler and only just below Idi Amin, Saddam Hussein, and Henry VIII. Hillary Clinton ranks between Napoleon and Nero.

  • Robot, drones to help collect crop testing data to bolster agricultural production

    A rumbling robot and several high-flying drones recently made an on-site appearance at Clemson University to burrow through and buzz above fifteen acres of experimental sorghum plots containing more than 2,800 replicated entries. The space-age devices are part of a collaborative project with Clemson University and other partners designed to significantly enhance the ease and frequency of data collection for crop testing in ways that will eventually benefit all agricultural production in South Carolina and around the world.

  • Global warming would make most cities too hot, humid to host summer Olympics

    The future of the summer Olympics may be in jeopardy because of rising heat and humidity due to climate change. By 2085, only eight Northern Hemisphere cities outside of Western Europe are likely to be cool enough to host the summer games. The authors considered only cities with at least 600,000 residents, the size considered necessary for hosting the games. Cities with elevations over a mile above sea level were omitted as such an altitude (for example, Mexico City in 1968) faced challenges of their own.

  • Economic growth will not counterbalance increasing climate change-related damage

    More than 50 percent of all weather-related economic losses on the globe are caused by damages due to tropical cyclones. New research finds that financial losses per hurricane could triple by the end of the century in unmitigated climate change, while annual losses could on average rise by a factor of eight. The researchers also concluded that economic growth will not be able to counterbalance the increase in damage.

  • Recovering rare-earth magnets from used hard drives

    The world’s most powerful magnets are manufactured using rare earth elements such as neodymium. These magnets are essential to the operation of everything from computer hard drives to electric and hybrid vehicles, electric bicycles, wind turbines, cell phones, air conditioners, and other appliances and industrial equipment. Need for the element is rising as demand for consumer products and clean energy technologies grows – but more than 95 percent of worldwide production of neodymium occurs outside the United States, mostly in China. A process developed at Oak Ridge National Laboratory for large-scale recovery of rare earth magnets from used computer hard drives will soon undergo industrial testing.

  • How a new source of water is helping reduce conflict in the Middle East

    Just a few years ago, in the depths of its worst drought in at least 900 years, Israel was running out of water. Now it has a surplus. This remarkable turnaround was helped by increasing conservation and re-use – but the biggest impact came from a new wave of desalination plants. Israel now gets 55 percent of its domestic water from desalination. Moreover, scientists and others look to desalination as a way to unite longtime enemies in a common cause.

  • July 2016 was the warmest month since modern record-keeping began in 1880

    July 2016 was the warmest July in 136 years of modern record-keeping, which began in 1880. The record warm July continued a streak of ten consecutive months dating back to October 2015 that have set new monthly high-temperature records.
