$300K challenge to uncover emerging biothreats
DHS S&T has launched the Hidden Signals Challenge, a $300,000 prize competition that seeks concepts for novel uses of existing data to uncover emerging biothreats. The Challenge calls upon data innovators from a wide variety of fields to develop concepts that will identify signals and achieve timelier alerts for biothreats in our cities and communities.

U.S. not prepared to identify perpetrators of biological attacks: Expert panel
When violent attackers use biological agents to inflict harm, not only must law enforcement attribute the crime to the correct perpetrator, they must also identify the pathogens used and their sources exactly and quickly. That was the focus of a special meeting last week hosted by the Blue Ribbon Study Panel on Biodefense.

Congressional amendments restore Maryland BioLab4 funding
Members of the Maryland congressional delegation attached amendments to the Homeland Security and Defense Department authorization bills to prevent the closure of the National Biodefense Analysis and Countermeasures Center (NBACC) at Fort Detrick, Maryland. President Trump’s budget for 2018 had eliminated funding for NBACC as part of cutting the budget of DHS Science and Technology Directorate (S&T) by 28 percent. At the end of May 2017, the research center received a letter from DHS stating that the facility’s closing procedures should start on 1October, with anticipated decommissioning by 30 September 2018.

Harnessing AI to catch disease fast
Up to 27,000 microbiology laboratories around the world could benefit from a ground-breaking automation technology. The Automated Plate Assessment System (APAS) can automatically screen microbiology culture plates for the presence of various disease-causing pathogens, revolutionizing the workflow in modern microbiology labs. The smart software uses artificial intelligence to analyze microbial growth in much the same way as a microbiologist would, but with faster and more consistent results.

Distinguishing virulent from harmless bacteria to help biological surveillance
Biological “detectives” are tracking down biothreats such as the bacteria that causes tularemia (“rabbit fever”), but they constantly face the challenge of avoiding false positives. Sounding the alarm over a bioattack, only to find it’s a harmless relative in the same genus, reduces credibility and public trust. Researchers are narrowing down the confusion over Francisella bacteria, a few species of which include highly virulent human and animal pathogens, fish pathogens, opportunistic human pathogens, tick endosymbionts, and free-living isolates inhabiting brackish water.

Identifying toxic threats, preparing for surprise
Predicting chemical attacks is no small task, especially when there are so many toxic substances. There is no crystal ball to aid us in sorting through them all to identify and characterize the potential threats. Instead, intelligence and defense communities use a broad network of tools to forecast hazards to safeguard our warfighters and nation. A new project from the Defense Threat Reduction Agency (DTRA) seeks to improve the U.S. defensive capability by creating a crystal ball to more rapidly determine the toxicity of such chemical hazards and increase our ability to prepare for surprise.

Stacking countermeasures for layered defense against chemical, biological threats
Just as we must protect computer systems against assaults in the form of viruses and trojans in the cyber world, we must protect our soldiers from a multitude of chemical and biological threats on the battlefield. No one countermeasure can mitigate every threat, which is why the Joint Science and Technology Office at the Defense Threat Reduction Agency is developing a portfolio of novel capabilities and medical countermeasures to protect our troops.

Device rapidly, accurately, inexpensively detects Zika virus at airports, other sites
About the size of a tablet, a portable device that could be used in a host of environments like a busy airport or even a remote location in South America, may hold the key to detecting the dreaded Zika virus accurately, rapidly and inexpensively using just a saliva sample. While scientists across the world are scrambling to find some sort of immunization, researchers are working to develop a diagnostic tool to reduce the impact of the outbreak until a vaccine is identified.

Biological emergences: Incremental progress not enough
While acknowledging some positive efforts over the past year by the White House and Congress, the bipartisan Blue Ribbon Study Panel on Biodefense says the incremental progress is not enough to defend against biological emergencies, let alone catastrophic events. The report, Biodefense Indicators – One Year Later, Events Outpacing Federal Efforts to Defend the Nation, states that while the biological threat is real and continues to grow, our nation remains woefully under-prepared for dangerous biological incidents.

Shark antibodies for chemical, biological threat detection, treatment
New research shows that shark antibodies offer new alternatives to chemical and biological threat detection and treatment tools. In an era of Department of Defense belt-tightening, the goal is to find more innovative, cost-effective approaches to protecting our warfighters.

New technology pinpoints water contamination sources
When the local water management agency closes your favorite beach due to unhealthy water quality, how reliable are the tests they base their decisions on? As it turns out, those tests, as well as the standards behind them, have not been updated in decades. Now scientists have developed a highly accurate, DNA-based method to detect and distinguish sources of microbial contamination in water.

Assessing the risk from Africa as Libya loses its chemical weapons
Libya’s remaining chemical weapons left over from the Gaddafi regime are now being safely disposed of in a German facility. This eliminates the risk of them falling into the wrong hands. But can these same hands acquire weapons of mass destruction from the rest of Africa? The disposal of Libya’s chemical weapons has lowered the risk of weapons of mass destruction in Africa. But we have seen how far non-state actors are willing to go to either produce or steal such weapons. For example, analysts envision militants known as “suicide infectors” visiting an area with an infectious disease outbreak like Ebola purposely to infect themselves and then using air travel to carry out the attack. Reports from 2009 show forty al-Qaeda linked militants being killed by the plague at a training camp in Algeria. There were claims that they were developing the disease as a weapon. The threat WMD pose cannot be ignored. African countries, with help from bilateral partners and the international community, have broadened their nonproliferation focus. They will need to keep doing so if the goal is effectively to counter this threat.

FBI’s WMD Directorate marks its first decade
If you can imagine a disaster involving explosives or the release of nuclear, biological, chemical, or radioactive material, there is a pretty good chance a group of subject-matter experts within the FBI has built an elaborate scenario around it and tested how well emergency responders face up to it. It is the main jobs of the Weapons of Mass Destruction (WMD) Directorate — to imagine worst-case scenarios and then devise ways to prevent and prepare for them. The Directorate was created ten years ago, on 26 July 2006.

“Second skin” uniform protects soldiers from biological, chemical agents in the field
In work that aims to protect soldiers from biological and chemical threats, scientists have created a material that is highly breathable yet protective from biological agents. This material is the first key component of futuristic smart uniforms that also will respond to and protect from environmental chemical hazards.

Using gels for biological decontamination
Removing chemical, biological, radiological, and toxic contaminants from a range of surface types could be as easy as peeling off a sticker thanks to research conducted by scientists at the U.S. Army’s Edgewood Chemical Biological Center (ECBC) and industry partner CBI Polymer.The researchers explored how a HydroGel can be modified to decontaminate surfaces contaminated with biological agents.
