Immune Molecule Protects Against Zika Virus Infection in Animal Models

A molecule naturally produced by the immune system protects mice and monkeys against Zika virus infection, an international team of researchers has found. Administering the molecule, called 25-hydroxycholesterol (25HC), to pregnant mice reduced Zika virus infection in the fetal brain and protected against Zika-induced microcephaly.

New UN Supply Chain System to Slash Delays, Save Lives in Large-Scale Health Crises

In collaboration with partners and as a part of a global supply chain network, the United Nations (UN) emergency food relief agency has set about developing the first-ever information platform to better manage supply chains and efficiently match deliveries with demand in responding to large-scale health emergencies such as pandemic outbreaks.

Oral Delivery System Could Make Vaccinations Needle-Free

Patients could one day self-administer vaccines using a needleless, pill-sized technology that jet-releases a stream of vaccine inside the mouth, according to a proof-of-concept study conducted at University of California-Berkeley. The technology is a step toward improved oral vaccine delivery, which holds the promise of building immunity in the mouth’s buccal region of cells, where many infections enter the body.

DHS Developed Software Powers Humanitarian Project

Krona, software originally developed at the U. S. Department of Homeland Security’s National Biodefense Analysis and Countermeasures Center (NBACC) to sequence DNA for biodefense, is now being used by Microsoft to sequence mosquito DNA in the fight against disease.

NRL Develops Lighter, Field Repairable Transparent Armor

Research chemists at U.S. Naval Research Laboratory (NRL) have developed and patented a transparent thermoplastic elastomer armor to reduce weight, inherent in most bullet-resistant glass, while maintaining superior ballistic properties. In addition to being transparent, and lighter than conventional bullet-resistant glass, it also is repairable in the field.

DHS S&T Invites Counter UAS Developers to Submit Tech for Assessment

The Department of Homeland Security (DHS) Science and Technology Directorate (S&T) is inviting developers of counter unmanned aerial system (C-UAS) technologies to participate in technology assessments. Selected C-UAS technology solutions will be assessed in an operationally relevant environment. Based on the findings, DHS S&T will provide best practices and strategies to federal, state and local law enforcement agencies.

Yellow Fever in the Americas-Current Outbreak Warrants Close Watch

The unusually large outbreak of yellow fever now occurring in rural Brazil deserves careful attention by world health authorities. “In light of the serious nature of this historically devastating disease, public health awareness and preparedness, even for individual cases, is critical,” said Dr. Anthony S. Fauci and Dr. Catherine Paules of the National Institute of Allergy and Infectious Diseases.

The United States Department of Agriculture (USDA) National Veterinary Services Laboratories has confirmed the full subtype for the highly pathogenic H7 avian influenza reported in Lincoln County, Tennessee. USDA continues to work with the Tennessee Department of Agriculture on the joint incident response. An epidemiological investigation is underway to determine the source of the infection.

WHO Stresses Urgent Need for R&D for Drug-Resistant TB Alongside Newly-Prioritized Antibiotic-Resistant Pathogens

The World Health Organization (WHO) reaffirms the critical need for research and development (R&D) of new antibiotics to tackle the threat of drug-resistant tuberculosis (TB), as well as other antibiotic-resistant pathogens that have recently been prioritized as posing great risk to human health.
