Real-time Imaging to Help Prevent Deadly Dust Explosions
Dust explosions can be among the most dangerous and costly workplace incidents. Dust builds up in agricultural, powder-handling or manufacturing settings, causing hazards to employees and posing the risk of exploding. Researchers have developed an image- and video-based application using OpenCV algorithms that detect explosible suspended dust concentration.

Bay Area Coastal Flooding Triggers Region-Wide Commute Disruptions
Researchers have modeled how coastal flooding will impact commutes in the Bay Area over the next twenty years. Regions with sparse road networks will have some of the worst commute delays, regardless of their distances from the coast.

What is Ammonium Nitrate, the Chemical that Exploded in Beirut?
Ammonium nitrate has the chemical formula NH₄NO₃. Produced as small porous pellets, or “prills,”it’s one of the world’s most widely used fertilizers. It is also the main component in many types of mining explosives, where it’s mixed with fuel oil and detonated by an explosive charge. For an industrial ammonium nitrate disaster to occur, a lot needs to go wrong. Tragically, this seems to have been the case in Beirut.

Consumers Do Not Fully Trust Smart Home Technologies
Researchers investigating the trust consumers have in “smart home” – homes in which smart devices are connected to each other to create an “internet of things” (IoT) — found that consumers were worried about the likelihood of security incidents. Businesses and policymakers will have to work together to gain consumer trust in smart home technologies.

Protection against Terrorist Attacks with Homemade Explosives
Terrorist attacks often feature the use of homemade explosives. For the police and security forces to be able to take appropriate precautions and assess the damage after an attack, they need access to the right kind of tools. Researchers have now developed a sophisticated risk-analysis system to help prevent such attacks. At the same time, the software-based system assists with the forensic investigation of such incidents.

“Worst case” CO2 Emissions Scenario Best Match for Assessing Climate Risk: Report
Four scenarios known as Representative Concentration Pathways (RCPs) were developed in 2005 to describe the potential scope and impact of global warming. The worst-case scenario was RCP 8.5, referring to the concentration of carbon that delivers global warming at an average of 8.5 watts per square meter across the planet (the best-case scenario was RCP 2.6). Scientists now argue that the RCP 8.5 CO2 emissions pathway — the worst-case scenario — is the most appropriate for conducting assessments of climate change impacts by 2050.

It’s a Bird... It’s a Plane... It’s Superman? No: It’s a Flapping-Wing Drone
A drone prototype that mimics the aerobatic maneuvers of one of the world’s fastest birds, the swift, is being developed by an international team of aerospace engineers in the latest example of biologically inspired flight. The 26 gram ornithopter (flapping wing aircraft) which can hover, dart, glide, brake and dive just like a swift, making them more versatile, safer and quieter than the existing quadcopter drones.

More Frequent Coastal Flooding Threatens 20 percent of global GDP
Coastal flooding across the world is set to rise by around 50 percent due to climate change in the next 80 years, endangering millions more people and trillions of dollars more of coastal infrastructure. The land area exposed to an extreme flood event will increase by more than 250,000 square kilometers globally, an increase of 48 percent or over 800,000 square kilometers. This would mean about 77 million more people will be at risk of experiencing flooding, a rise of 52 percent to 225 million. The economic risk in terms of the infrastructure exposed will rise by up to $14.2 trillion, which represents 20 percent of global GDP.

Autotalks Deploys Smart Traffic Signals in Alpharetta, Georgia
When an emergency vehicle comes speeding towards an intersection, drivers know to pull over and give the ambulance or firetruck the right of way. Israeli automotive technology firm Autotalks takes that one step further by sending a wireless signal from the emergency responder to the traffic lights so the signals will automatically change to stop cross traffic.

Preparing for an Explosive Attack
Explosives are a popular choice among terrorists for causing disruption, casualties and destruction. Although chemical, biological, radiological and nuclear (CBRN) weapons may cause much more damage, explosives can still be the first choice because they are relatively easy to make, transport and use. DHS S&T says it wants to make sure that state and local leaders have choices, too, by arming them with technology to plan for worst-case scenarios and mitigate the fallout of terrorist attacks.
