DHS to Equip Federal Immigration Agents with Body Cameras; New Tech Emerges in Medicine and Computing

WASHINGTON D.C. – The Department of Homeland Security (DHS) began deploying body-worn cameras to federal immigration agents in Minneapolis, with plans to expand the program nationwide as funding becomes available, Secretary Kristi Noem announced Monday. The move follows pressure from Democrats and support from some Republicans amid ongoing scrutiny of the Administration's immigration policies, according to Time.

"Effective immediately we are deploying body cameras to every officer in the field in Minneapolis," Noem said in a post on X, adding, "We will rapidly acquire and deploy body cameras to DHS law enforcement across the country." She noted that she had spoken with White House border czar Tom Homan, who is overseeing federal immigration operations.

In other news, researchers are making strides in medicine and computing. A team at ETH Zurich has developed an infrared-activated hydrogel that utilizes lysozyme "nets" to combat resistant bacteria and promote wound healing, according to Phys.org. The hydrogel aims to address the growing problem of antibiotic resistance, which contributes to an estimated 7.7 million deaths worldwide each year due to bacterial infections.

Meanwhile, a collaborative research team from the Daegu Gyeongbuk Institute of Science and Technology (DGIST) and KAIST has discovered a new memory principle using a stacked graphene sandwich that enables information to be written and erased electrically without traditional ferroelectrics, Phys.org reports.

In related technology news, VentureBeat reports that enterprises adopting Retrieval-Augmented Generation (RAG) for Large Language Models (LLMs) are recognizing retrieval as a critical infrastructure component. A system-level model is being proposed to prioritize freshness, governance, and evaluation in retrieval platform design, treating it with the same rigor as other core infrastructure elements.

The news arrives as the world mourns the death of William Foege, the physician and epidemiologist who played a crucial role in eradicating smallpox, one of humanity's oldest killers, Vox reports. Foege received the Presidential Medal of Freedom in 2012 for his work.
