The Homeland Defense (HD) Digest is a curated bi-weekly news summary from worldwide sources, showing headlines of innovative, emerging technologies in HDIAC's eight focus areas.
Join HDIAC on Tuesday, June 9, from 1200 to 1300 EDT for our next webinar presentation. The current nuclear threat is growing as Russia, China, Iran, and North Korea continue to push forward nuclear agendas. In this webinar, Mr. Mark Diglio, the US Army's CBRN Survivability Program Manager, will discuss the growing CBRN threat, CBRN survivability acquisition policy/requirements, renewed US Army priorities for CBRN survival, rapid acquisition initiatives, development considerations for survivability, mission critical concerns, and future survivability considerations.
Payments With Windows Hello Face And Fingerprint Biometrics Added To Google Chrome - Biometric Update
Google Chrome has added support for biometric payment authentication for Windows 10 users with facial or fingerprint recognition through Windows Hello, XDA-Developers reports.
Next-Generation Solar Cells Pass Strict International Tests - Science Daily
Australian scientists have for the first time produced a new generation of experimental solar energy cells that pass strict International Electrotechnical Commission testing standards for heat and humidity.
Snapshot: Helping Law Enforcement Solve and Prevent Chemical-Related Violence - Homeland Security S&T
Imagine that in the course of an investigation, law enforcement officers suspect the presence of a clandestine laboratory processing illicit drugs. Upon the execution of a search warrant, these officers discover a clandestine laboratory hidden in the basement, full of bottles and containers with chemicals. For personal and public safety, as well as potential criminal prosecution, the officers must be able to identify both the illicit substances and all substances used to make them. For officers who likely are not chemists, how can they do this quickly and safely? What if they could enter the list of chemicals in a search engine or a special database and discover that these chemicals are the reagents or ingredients for the production of a toxic gas?
Molecules released into the blood following mild traumatic brain injury (TBI) may be indicators of neuronal damage associated with conditions such as post-traumatic stress disorder (PTSD) and depression, researchers from the National Institute of Nursing Research (NINR), part of the National Institutes of Health, have found. This study included military veterans and servicemembers who were enrolled in the Chronic Effects of Neurotrauma Consortium (CENC)(link is external) multicenter observational study of the long-term effects of mild TBI and is published in Neurology.
Tests on new designs for next-gen solar cells can now be done in hours instead of days thanks to a new system built by scientists at Australia's Monash University, incorporating 3D-printed key components.
The investigational antiviral remdesivir is superior to the standard of care for the treatment of COVID-19, according to a report published today in the New England Journal of Medicine. The preliminary analysis is based on data from the Adaptive COVID-19 Treatment Trial (ACTT), sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. The randomized, controlled trial enrolled hospitalized adults with COVID-19 with evidence of lower respiratory tract involvement (generally moderate to severe disease). Investigators found that remdesivir was most beneficial for hospitalized patients with severe disease who required supplemental oxygen. Findings about benefits in other patient subgroups were less conclusive in this preliminary analysis.
The Material Shields Wearers From Chemical And Biological Agents And Could Pave The Way To Smart Uniforms For Troops And First Responders - Nextgov
A Lawrence Livermore National Laboratory-led team of scientists has developed a breathable, protective smart fabric-deemed a "second skin"-that's designed to shield wearers by responding, itself, to chemical and biological agents.
Protect and Defend - Harvard Medical School
With the global number of confirmed cases at nearly 5 million and more than 300,000 deaths from COVID-19, much remains unknown about SARS-CoV-2, the virus that causes the disease. Two critical questions are whether vaccines will prevent COVID-19 and whether individuals who have recovered from COVID-19 are protected when they encounter the virus again.
Lend Me Your Ears: Securing Smart-Home Entry With Earprints - Homeland Security
Fingerprints and DNA are well-known forms of biometrics, thanks to crime dramas on television and at the movies. But as technology drives us toward the Internet of Things-the interconnection of computer devices in common objects-other forms of biometrics are sure to enter the cultural consciousness beyond use as forensics tools such as face recognition and retinas, veins, and palm prints. Researchers say that "earprints" could one day be used as person identification to secure smart homes via smartphones.
Scientists Inject Proteins Into Eukaryontic Cells - Science Daily
When bacteria such as Salmonella or Yersinia cause fever, diarrhea or abdominal pain, tiny "injection needles" are at work: their type 3 secretion system, or T3SS for short, shoots bacterial virulence proteins directly into the eukaryotic host cells. Researchers have thought of using bacterial injection devices to introduce proteins into eukaryotic cells. A research team has now succeeded in controlling the injection system optogenetically, i.e. with light. In the future this will enable to use the system in biotechnological or medical applications.
