• Sinking ground in San Francisco Bay exacerbates flooding from rising sea levels

    New research shows that sections of the San Francisco Bay shoreline are sinking at rates of nearly half an inch (10 millimeters) a year. But knowledge of where the ground in the Bay Area is sinking, and by how much, is not included in the official planning maps that authorities use to assess the local flooding risk from rising sea levels. The researchers used radar imaging to measure elevations to discover important gap in planning for sea level rise in Bay Area.

  • Combining old and new to create a novel power grid cybersecurity tool

    An innovative R&D project that combines cybersecurity, machine learning algorithms and commercially available power system sensor technology to better protect the electric power grid has sparked interest from U.S. utilities, power companies and government officials. Creating innovative tools and technologies to reduce the risk that energy delivery might be disrupted by a cyber incident is vital to making the nation’s electric power grid resilient to cyber threats.

  • Microgrids have a large impact

    As many as 1.3 billion people lack access to electrical power. Engineers make strides in technologies that promise to make electrical power more accessible almost anywhere on the planet. One of his solutions is microgrids, which provide independent power generation and storage systems capable of operating as mobile or standalone systems or as a supplemental part of larger conventional power grids.

  • MIT energy conference speakers say transformation can happen fast

    The pace of advances in key clean energy technologies has been growing faster than many experts have predicted, to the point that solar and wind power, combined with systems for storing their output, can often be the least expensive options for new types of power-generating capacity. In fact, a radical transformation of the world’s energy landscape is well-underway, experts say.

  • AI profiling: the social and moral hazards of “predictive” policing

    While the use of AI predictions in police and law enforcement is still in its early stages, it is vital to scrutinize any warning signs that may come from its use. One standout example is a 2016 ProPublica investigation which found that COMPAS software was biased against black offenders. Society needs to maintain a critical perspective on the use of AI on moral and ethical grounds. Not least because the details of the algorithms, data sources and the inherent assumptions on which they make calculations are often closely guarded secrets. Those secrets are in the hands of the specialist IT companies that develop them who want to maintain confidentiality for commercial reasons. The social, political and criminal justice inequalities likely to arise should make us question the potential of predictive policing.

  • Small-drone threats to infantry units require development of countermeasures

    The emergence of inexpensive small unmanned aircraft systems (sUASs) that operate without a human pilot, commonly known as drones, has led to adversarial groups threatening deployed U.S. forces, especially infantry units. Although the U.S. Army and the U.S. Department of Defense (DOD) are developing tactics and systems to counter single sUASs, a new report emphasizes the need for developing countermeasures against multiple sUASs — organized in coordinated groups, swarms, and collaborative groups — which could be used much sooner than the Army anticipates. The committee that conducted the study developed a classified report that details its findings and recommendations, along with an unclassified public version that discusses key background issues presented in this news release.

  • Metal-eating microbes are cost-effective for recycling rare earth elements

    Today’s high-tech devices usually contain components made of rare earth elements (REEs), a class of metallic elements including neodymium and dysprosium. Despite this demand, and despite the fact that REEs are relatively common in the earth’s crust, REEs are difficult to obtain, and the U.S. currently does not produce a domestic supply. This scarcity of domestic REEs leaves manufacturers of everything from cellphones and computers to wind turbines and telescope lenses vulnerable to supply disruptions. have developed an economical way to recycle REEs using a bacterium called Gluconobacter oxydans.

  • Sea level rise requires new forms of decision making

    U.S, cities facing sea level rise need to look beyond traditional strategies for managing issues such as critical erosion and coastal squeeze, according to new research. Civil society initiatives must now play a crucial role in adapting society to climate change, and decision makers must seriously consider the tradeoff among three options: sea wall; beach-nourishment; and relocating coastal infrastructure.

  • Using artificial intelligence to predict criminal aircraft

    The ability to forecast criminal activity has been explored to various lengths in science fiction, but does it hold true in reality? It could for U.S. Customs and Border Protection (CBP). ) DHS S&T is developing a Predictive Threat Model (PTM) to help CBP’s Air and Marine Operations Center (AMOC) more quickly and efficiently identify and stop nefarious aircraft.

  • New framework for guiding controversial research still has worrisome gaps

    In December the Department of Health and Human Services (HHS) release lifted the funding moratorium on Gain of Function (GoF) research, following the controversial projects involving H5N1 in 2011. The “Framework for guiding funding decisions about proposed research involving enhanced potential pandemic pathogens” is similar to the January 2017 “P3C0 Framework,” and it came with the bonus of restoring funding for such research – but there are still considerable concerns with how GoF research is evaluated and if these frameworks have really addressed the gaps.

  • Bioengineers today emphasize the crucial ingredient Dr. Frankenstein forgot – responsibility

    Mary Shelley was 20 when she published “Frankenstein” in 1818. Two hundred years on, the book remains thrilling, challenging and relevant — especially for scientists like me whose research involves tinkering with the stuff of life. Talk of “engineering biology” makes a lot people squeamish, and technology can turn monstrous, but I read Mary Shelley’s “Frankenstein” not as an injunction against bioengineering as such. Rather, the story reveals what can happen when we – scientists and nonscientists alike – run away from the responsibilities that science and technology demand. Victor Frankenstein was certainly careless and perhaps a coward, unable to own up to the responsibility of what he was doing. We now know that science is best conducted with humility, forethought and in the light of day.

  • Extreme weather tests U.K. gas security to the limit

    The National Grid, which manages the U.K.’s energy network, warned that it might not have enough gas to meet demand on March 1, due to plummeting temperatures and issues with supply. It has since withdrawn the warning, saying the market response has boosted supplies. But Britain’s lack of flexible energy supply is a serious issue. This isn’t the first time such a warning has been issued and it probably won’t be the last.

  • If you want to know how to stop school shootings, ask the Secret Service

    While President Donald Trump has not shied away from offering suggestions on how to prevent school shootings – including one controversial idea to arm teachers – what often gets overlooked in the conversation is research on the subject that has already been done. This research includes one major study of school shootings conducted in part by the very agency charged with protecting the president of the United States himself - the U.S. Secret Service. Has this research been ignored or just forgotten?

  • Flood risk for Americans is greatly underestimated

    A new study has found that forty-one million Americans are at risk from flooding rivers, which is more than three times the current estimate—based on regulatory flood maps—of thirteen million people. The study is based on a new high-resolution model that maps flood risk across the entire continental United States, whereas the existing regulatory flood maps produced by the Federal Emergency Management Agency (FEMA) cover about 60 percent of the continental United States. Avoiding future losses is particularly important as average flood losses in the United States have increased steadily to nearly $10 billion annually.

  • Protecting soldiers from blast-induced brain injury

    Researchers have developed a new military vehicle shock absorbing device that may protect warfighters against traumatic brain injury (TBI) due to exposure to blasts caused by land mines. During Operations Iraqi Freedom and Enduring Freedom, more than 250,000 warfighters were victims of such injuries. Prior to this study, most research on blast-induced TBI has focused on the effects of rapid changes in barometric pressure, also known as overpressure, on unmounted warfighters.
