Innovation in Homeland Security Lives Between Sectors

#homelandsecurity #innovation

Having been involved in the creation of the Department of Homeland Security’s Science & Technology Directorate, and with decades of experience working at the intersection of government, industry, and academia, I have come to a simple but important observation: innovation in homeland security doesn’t happen in one area. Instead, it thrives where mission, research, and engineering come together.

Convergence is the catalyst. Cyber defense, autonomous systems, identity management, quantum computing, and photonics are all examples of technological advancements that didn’t develop in isolation. Their progress was the result of different sectors working together on shared goals, risk management, and practical use. Homeland security enterprise is constituted by a multi-sectoral nature: government sets mission needs, industry creates scalable solutions, and academia provides the necessary research. Real innovation happens when these areas come together.

Statistical data highlights the significance of this alignment. Research on cyber-behavior, for instance, demonstrates that organizational culture, national context, and employee backgrounds significantly impact risk outcomes. Practically speaking, this implies that secure systems cannot be developed in isolation. The human and institutional context is as crucial as technical advancements.

Consciousness as the foundation: New theory addresses nature of reality

Consciousness is fundamental; only thereafter do time, space and matter arise. This is the starting point for a new theoretical model of the nature of reality, presented by Maria Strømme, Professor of Materials Science at Uppsala University, in AIP Advances. The article has been selected as the best paper of the issue and featured on the cover.

Strømme, who normally conducts research in nanotechnology, here takes a major leap from the smallest scales to the very largest—and proposes an entirely new theory of the origin of the universe. The article presents a framework in which consciousness is not viewed as a byproduct of brain activity, but as a fundamental field underlying everything we experience—matter, space, time, and life itself.

Why the long interface? AI systems don’t ‘get’ the joke, research reveals

Powerful artificial intelligence (AI) systems, like ChatGPT and Gemini, simulate understanding of comedy wordplay, but never really “get the joke,” a new study suggests.

Researchers wanted to find out whether large language models (LLMs) can understand puns—also known as paronomasia—wordplay that relies on double meanings or sound-alike words, for an intended humorous or rhetorical effect.

While earlier studies suggest LLMs could process this type of humor in a similar way to humans, the team from Cardiff University and Ca’ Foscari University of Venice found AI systems mostly memorize familiar joke structures rather than actually understand them.

Hidden household toxin triples liver disease risk, study finds

PCE, a dry-cleaning chemical found in many everyday products, has been linked to tripled risk of serious liver damage. Scientists have uncovered a new environmental culprit behind liver disease: tetrachloroethylene (PCE), a chemical used in dry cleaning and household products. The study found that people with PCE exposure were three times more likely to develop severe liver scarring, even when traditional risk factors like alcohol or obesity were absent. The chemical is widespread in air, water, and consumer goods, making it a stealthy threat to public health.

Liver disease most often develops due to one of three major causes: excessive alcohol use, the buildup of fat in the liver associated with obesity, diabetes, and high cholesterol, or viral infections such as hepatitis B and C.

Researchers from Keck Medicine of USC have identified another potential cause of liver damage. A new study published in Liver International links tetrachloroethylene (PCE), a chemical widely used in dry cleaning and found in household products like adhesive glues, spot removers, and stainless steel polish, to serious liver harm.

NASA, SpaceX launch US–European satellite to monitor Earth’s oceans

About the size of a full-size pickup truck, a newly launched satellite by NASA and its partners will provide ocean and atmospheric information to improve hurricane forecasts, help protect infrastructure, and benefit commercial activities, such as shipping.

The Sentinel-6B satellite lifted off aboard a SpaceX Falcon 9 rocket from Launch Complex 4 East at Vandenberg Space Force Base in central California at 9:21 p.m. PST on Nov. 16. Contact between the satellite and a ground station in northern Canada occurred about 1 hour and 30 minutes later at 10:54 p.m. All systems are functioning normally.

“Understanding tidal patterns down to the inch is critical in protecting how we use our oceans every day on Earth,” said Nicky Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington. “Sentinal-6B will build upon the legacy of Sentinel-6 Michael Freilich by making sea level measurements that improve forecasts used by communities, businesses, and operations across the country. It also will support a safer reentry for our astronauts returning home, including crew from Artemis Moon missions.”
