• The geology and resources of 23 minerals critical for the United States

    It would be no exaggeration to say that without minerals, no aspect of our daily lives would be possible. From the high-tech devices we use to access the information superhighway to the cars and trucks we use to drive the freeways, from the urban jungle to rural farms, every aspect of our lives relies on minerals. Thus, access to sufficient supplies of these minerals is a crucial part of keeping our economy and our security running. In a new collection of articles, USGS geologists provide the latest on the geology and resources of twenty-three mineral commodities deemed critical to the economy and security of the United States.

  • Hotter temperatures will accelerate asylum-seekers migration to Europe

    New research predicts that migrants applying for asylum in the European Union will nearly triple over the average of the last fifteen years by 2100 if carbon emissions continue on their current path. The study suggests that cutting emissions could partially stem the tide, but even under an optimistic scenario, Europe could see asylum applications rise by at least a quarter.

  • Billion-dollar weather and climate disasters on the rise

    from 1980 to 2017, the United States has sustained 218 weather and climate disasters in which overall damages/costs reached or exceeded $1 billion (including CPI adjustment to 2017). The total cost of these 218 events exceeds $1.2 trillion. This total does not yet include the costs for Hurricanes Harvey, Irma and Maria. Between 1 January and 6 October 2017, there have been fifteen weather and climate disaster events with losses exceeding $1 billion each across the United States. The 1980–2016 annual average pf weather events with losses exceeding $1 billion each is 5.5 events (CPI-adjusted); the annual average for the most recent 5 years (2012–2016) is 10.6 events (CPI-adjusted).

  • NSF awards nearly $5.7 million to protect U.S. cyberspace

    The National Science Foundation (NSF) recently gave the nation’s cybersecurity professionals a boost with the inclusion of four new universities into its CyberCorps: Scholarship for Service (SFS) program. NSF awarded nearly $5.7 million, with an expected total of almost $16.6 million over the next five years, to universities in Illinois, Maryland, Louisiana, and Texas. The schools will use the money to provide scholarships consisting of full tuition and a stipend up to $34,000 to individuals willing to work after graduation in a cybersecurity position for federal, state, local or tribal governments.

  • Proof of randomness for stronger future digital security

    Nearly all secure online traffic — from shopping to banking to communications — relies on a technique of randomly generating a number that serves as a key to unlock encrypted communication. The problem is that small programming errors can make these systems vulnerable, and those vulnerabilities can often be very difficult to detect. In an effort to block emerging threats to online security, researchers have developed a method to verify the strength of random number generators that form the basis of most encryption systems.

  • DARPA’s Software Defined Radio (SDR) Hackfest explores solutions for spectrum challenges

    The DARPA Bay Area Software Defined Radio (SDR) Hackfest came to a close on Friday, 17 November at the NASA Ames Conference Center in Moffett Field, California. During the weeklong event, over 150 members of the SDR community came together to discuss, innovate, and ideate around the future of software radio technology and its potential to address challenging communications issues that are emerging due to the increasingly congested electromagnetic (EM) spectrum and the proliferation of wireless-enabled devices.

  • New simulator tool allows testing the explosive vulnerabilities of aircraft

    Each day, more than twenty-six thousand commercial flights transport passengers and cargo to destinations around the world. S&T’s Commercial Aircraft Vulnerability and Mitigation (CAVM) program supports testing and evaluation efforts to assess potential vulnerabilities and evaluate countermeasures that can mitigate the impact of explosives on commercial aircraft. Newer generations of commercial aircraft fuselages are being made with composite materials, such as carbon fiber reinforced plastic, so CAVM needs to develop a sustainable and representative testing solution in order to all evaluations of new composite aircraft structures to explosive-based threats could continue as needed.

  • GAO: DoD needs to do more on climate adaptation

    Last week, the Government Accountability Office (GAO), issued a report titled Climate Change Adaptation: DoD Needs to Better Incorporate Adaptation into Planning and Collaboration at Overseas Installations. The report found that the Department of Defense (DoD) needs to better incorporate adaptation to climate change into planning and collaboration at overseas installations.

  • U.S. ends 3-year ban on research involving enhanced-lethality viruses

    The U.S. National Institutes of Health (NIH) yesterday announced it was ending its three-year moratorium on funding of gain-of-function research, that is, research which aims to make extremely dangerous viruses even more dangerous in order to find a vaccine or cure for them. The U.S. government instituted the ban in 2014, against the backdrop of rising worries that these “gain-of-function” studies would allow scientists to increase the ability of the infectious disease to spread by enhancing its pathogenicity, or its ability to cause disease. Scientists who supported continuing research involving enhancing the transmissibility of infectious disease were not helped by a series of safety mishaps at federal research facilities.

  • Helping secure first responder apps from cyberattacks

    In emergency and disaster situations, mobile devices and apps enable public-safety professionals to receive and share critical information in real-time, which enhances the delivery of life-saving services. As reliance on mobile technology grows, it is important that mobile apps used by public safety are free of malware or vulnerabilities.

  • Computer modeling aids solder reliability in nuclear weapons

    Solder isn’t the first thing that comes to mind as essential to a nuclear weapon. But since weapons contain hundreds of thousands of solder joints, each potentially a point of failure, Sandia National Laboratories has developed and refined computer models to predict their performance and reliability.

  • South Florida faces increasing inland flood threat

    As South Florida raises groundwater levels to fight saltwater intrusion, the threat of inland flooding will only increase, according to newly published research results. Although high groundwater levels in South Florida are a major contributor to inland floods, especially during the wet season or extreme rain events, traditional flood models don’t account for the groundwater beneath our feet, scientists have found.

  • New technique could help coal plants reduce greenhouse gas emissions

    Carbon capture could help the nation’s coal plants reduce greenhouse gas emissions, yet economic challenges are part of the reason the technology isn’t widely used today. That could change if power plants could turn captured carbon into a usable product.

  • Globe had third warmest year to date and fifth warmest November on record

    With a warm start to the year and only one month remaining, the globe remains on track to go down as the third warmest year in the 138-year climate record. Arctic and Antarctic sea ice coverage remain at near-record lows.

  • Biosecurity conference fosters international, multidisciplinary collaboration

    Biosecurity prevents unauthorized access, loss and intentional release of biological pathogens, information and equipment that may cause harm. Biosecurity professionals from across the United States and Mexico gathered on Arizona State University’s Tempe campus 7-8 December, the first time a biosecurity conference of this scope had taken place in Arizona and one of the largest ever to be held in the United States. Leaders in the field shared multidisciplinary approaches and perspectives on biosecurity.
