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.
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.
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.
This podcast covers everything from police reform and evidence-based research to body-worn cameras and police departments’ use of social media. Hear what some of today’s top criminal justice experts think about training, transparency, accountability, community policing, crisis intervention, and federal support of the police.
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.
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.
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.
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.
Lawrence Livermore National Laboratory (LLNL) scientists and collaborators at Los Alamos National Laboratory (LANL) for the first time have taken 3D snapshots of operating high explosive detonators. The research is important for assessing aging margins, safety and performance, and in developing new and improved detonation designs.
