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.

Attributing Biological Weapons Use
Why is attribution of BW use important? During a biological incident, including BW use, what evidence might provide valuable information to facilitate attribution? What is the state of the science for determining the origin of a biological incident, including BW use? What capabilities does DoD possess or could it develop to facilitate attribution of BW use?

A Non-Proliferation Solution: Using Antineutrinos to Surveil Nuclear Reactors
Antineutrinos generated in nuclear fission can be measured to remotely monitor the operation of nuclear reactors and verify that they are not being used to produce nuclear weapons, scientists report. Thanks to a newly developed method, it is now possible to estimate a reactor’s operation status, fuel burnup, and fuel composition based entirely on its antineutrino emissions. This technique could contribute massively to nuclear non-proliferation efforts and, in turn, safer nuclear energy.

Speedier Security Screening in the Palm of the Hand
Though pat downs are currently an essential element of keeping travelers safe at the airport, it slows the screening process for people waiting in line and can be an uncomfortable experience for the passenger being screened. Reducing the need for pat downs may soon be easier.

Iran Triples Production of Enriched Uranium
Iran has tripled its production of uranium enriched to 60 percent, after slowing down of production earlier this year, the International Atomic Energy Agency (IAEA) reported on Tuesday. Iran, free of the restrictions it accepted as part of the 2015 deal, is now producing about 9 kg a month of uranium enriched to 60 percent.

Chlorine Is a Highly Useful Chemical That’s Also Extremely Dangerous − Here’s What to Know About Staying Safe Around It
Chlorine is extremely toxic, and because it’s ubiquitous in many industries across the U.S., it often is released in chemical accidents and spills. As with other household chemicals, it is very important to understand its risks, read labels before using it, store it in its original container in a secure place and dispose of it safely.
