Cases of a potentially fatal infection from a seawater-borne pathogen have increased off the US Atlantic coast as ocean waters warmed over the last 30 years and are expected to rise further in future because of climate change, according to a study published on Thursday by Scientific Reports, an open-access journal for research on the natural sciences and other topics.

The incidence of infections from Vibrio vulnificus, a pathogen that thrives in shallow, brackish water, was eight times greater in the Eastern US in 2018 than it was in 1988, and its range shifted northward to areas where waters were previously too cold to support it, according to the paper, “Climate Warming and Increasing Vibrio Vulnificus Infections in North America,” by academic researchers in the US, England, and Spain.

By the middle of the 21^st century, the pathogen is expected to become more common in major population centers, including New York City, and by the end of the century, infections may be present in every US Atlantic coast state if carbon emissions follow a medium- to high-level trajectory, the report said.

Water purification systems installed in two ice machines in a Boston hospital were supposed to make the water taste and smell better for patients on a surgery floor—but it ended up killing three of them, an investigation found.

The purification systems inadvertently stripped chlorine from the municipal tap water, allowing bacteria normally found at low levels to flourish and form biofilms inside the machines. This led to infections in four vulnerable cardiac-surgery patients who had prolonged stays on the hospital floor. Three of them died of their infections.

Researchers detailed the case cluster and ensuing investigation in a study published Monday in the Annals of Internal Medicine.

A judge in Washington issued an arrest warrant Thursday for a Tacoma woman who has refused to have her active, contagious case of tuberculosis treated for over a year, violating numerous court orders. The judge also upheld an earlier order to have her jailed, where she can be tested and treated in isolation.

On Thursday, the woman attended the 17th court hearing on the matter and once again refused a court order to isolate or comply with testing and treatment—an order that originally dates back to January 19, 2022. Pierce County Superior Court Judge Philip Sorensen rejected her objections to being treated and upheld a finding of contempt. Though it remains unclear what her objections are, the woman's lawyer suggested it may be a problem with understanding, according to The News Tribune. The Tacoma-Pierce County Health Department, however, argued that she “knowingly, willfully, and contemptuously violated this court’s orders,” noting the lengthy process and numerous proceedings and discussions in which interpreters, translated documents, and speakers of her native language were made available.

Sorenson ordered a civil warrant for her arrest, to be enforced on or after March 3, and again ordered her to jail to undergo involuntary testing and treatment until health officials deem it safe to release her. The order also authorized the Pierce County Jail to place her in a facility equipped to handle her isolation, testing, and treatment.

The US Department of Transportation is investigating allegations that Elon Musk's brain-computer interface company, Neuralink, violated federal transportation regulations when it shipped contaminated implants removed from the brains of deceased research monkeys infected with multiple types of dangerous pathogens. The alleged violations could have put humans at risk of exposure to hazardous germs, including drug-resistant bacteria and a potentially life-threatening herpes virus.

Reuters was the first to report the department's investigation, which was sparked by allegations brought Thursday by the Physicians Committee for Responsible Medicine (PCRM), a medical group that advocates for animal welfare in medical research. The Department of Transportation confirmed to Ars on Friday that it has opened a standard investigation of Neuralink in response to PCRM's allegations.

In a letter addressed to Transportation Secretary Pete Buttigieg and William Schoonover, associate administrator of the department's Pipeline and Hazardous Material Safety Administration, the PCRM laid out its evidence for possible violations of hazardous material transportation regulations based on a trove of documents and emails obtained through public record requests. The advocacy group says the evidence shows Neuralink's contaminated hardware was not properly packaged to prevent exposure to humans and that Neuralink employees who transported the material had failed to undergo legally required training on how to safely transport such material.

The Department of Justice's consumer-protection branch has opened a criminal investigation into the conduct of Abbott Laboratories, one of the country's largest formula makers at the center of a contamination scandal and ongoing nationwide shortage.

The existence of the investigation was first reported by The Wall Street Journal. Though the DOJ is not commenting on it, a spokesperson for Abbott said the department has informed them of the investigation and that the company is "cooperating fully."

Federal regulators last year found numerous violations and "egregiously unsanitary" conditions at Abbott's Sturgis, Michigan, plant, the largest formula factory in the country. The regulators previously received reports that at least four babies who drank formula made at that facility fell ill with dangerous infections of the bacterium Cronobacter sakazakii, which had also been detected in the plant. Two of the infants died.
