Using people with cell phones as surveillance nodes
Eighty-eight percent of Americans now own a cell phone, forming a massive network that offers scientists a wealth of information and an infinite number of new applications; with the help of these phone users — and their devices’ cameras, audio recorders, and other features — researchers envision endless possibilities for gathering huge amounts of data

Bi-plane to revive supersonic travel
Researchers say that the best way to revive supersonic air travel – which came to an end with the retirement of the Concorde in 2003 – would be by building a plane with two wings to a side; computer models show that a bi-plan produces significantly less drag than a conventional single-wing aircraft at supersonic cruise speeds

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

Computer spots liars by looking at the way they talk
Computer scientists are exploring whether machines can read the visual cues of an individual’s conduct to discover whether or not that individual is lying; in a study of forty videotaped conversations, an automated system the researchers developed correctly identified whether interview subjects were lying or telling the truth 82.5 percent of the time

Robot for shipboard firefighting
In both war and peace, fire in the shipboard environment is serious and frequently results in excessive damage and high repair costs because the fire is not detected or controlled adequately; researchershave developed a humanoid robot that could fight fires on the next generation of combatants

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
By Trina West
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?
By Zulfikar Abbany, Julia Vergin, and Katja Sterzik
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
By Michael Matz
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.
The Tech Apocalypse Panic is Driven by AI Boosters, Military Tacticians, and Movies
By Matthew Guariglia
From popular films like a War Games or The Terminator to a U.S. State Department-commissioned report on the security risk of weaponized AI, there has been a tremendous amount of hand wringing and nervousness about how so-called artificial intelligence might end up destroying the world. There is one easy way to avoid a lot of this and prevent a self-inflicted doomsday: don’t give computers the capability to launch devastating weapons.
