Iron is key to reversing climate change
Scientists and politicians are trying to devise ways to reduce CO2 emissions — but when it comes to getting rid of the CO2 that is already there, nature itself plays an important role: carbon dioxide is removed from the atmosphere and safely trapped on the ocean floor through a natural reaction that fixes the molecule to organic carbon on the surface of large bodies of water

U.S. files trade charges against China over rare minerals
China mines and sells about 97 percent of the world’s rare Earth elements – seventeen metals used in cell phones, advanced batteries, wind turbines, and more; the Chinese, in violation of WTO rules, have manipulated the export of these minerals in order to weaken the techno logy sectors of other countries, and punish countries over political disputes

Rethinking the toilet model in developing countries
More than 2.6 billion people around the world lack access to basic sanitation, and more than 40 percent of the world’s population lack access to even the simplest latrine; the lack of sanitation creates serious problems, including environmental pollution, unsafe surroundings, and increasing the outbreak of lethal epidemic diseases such as cholera; Swedish company offers a solution

Origami-inspired paper sensor tests for malaria, HIV for less than 10 cents
Chemists have developed a 3-D paper sensor that may be able to test for diseases such as malaria and HIV for less than ten cents a pop; such low-cost, point-of-care sensors could be useful in the developing world, where the resources often do not exist to pay for lab-based tests, and where, even if the money is available, the infrastructure often does not exist to transport biological samples to the lab

The long view
Autonomous Vehicle Technology Vulnerable to Road Object Spoofing and Vanishing Attacks
Researchers have demonstrated the potentially hazardous vulnerabilities associated with the technology called LiDAR, or Light Detection and Ranging, many autonomous vehicles use to navigate streets, roads and highways. The researchers have shown how to use lasers to fool LiDAR into “seeing” objects that are not present and missing those that are – deficiencies that can cause unwarranted and unsafe braking or collisions.
Tantalizing Method to Study Cyberdeterrence
Tantalus is unlike most war games because it is experimental instead of experiential — the immersive game differs by overlapping scientific rigor and quantitative assessment methods with the experimental sciences, and experimental war gaming provides insightful data for real-world cyberattacks.
Prototype Self-Service Screening System Unveiled
TSA and DHS S&T unveiled a prototype checkpoint technology, the self-service screening system, at Harry Reid International Airport (LAS) in Las Vegas, NV. The aim is to provide a near self-sufficient passenger screening process while enabling passengers to directly receive on-person alarm information and allow for the passenger self-resolution of those alarms.
Falling Space Debris: How High Is the Risk I'll Get Hit?
An International Space Station battery fell back to Earth and, luckily, splashed down harmlessly in the Atlantic. Should we have worried? Space debris reenters our atmosphere every week.
Testing Cutting-Edge Counter-Drone Technology
Drones have many positive applications, bad actors can use them for nefarious purposes. Two recent field demonstrations brought government, academia, and industry together to evaluate innovative counter-unmanned aircraft systems.
Strengthening the Grid’s ‘Backbone’ with Hydropower
Argonne-led studies investigate how hydropower could help add more clean energy to the grid, how it generates value as grids add more renewable energy, and how liner technology can improve hydropower efficiency.
