"Russian health authorities have taken precautionary measures in response to the death of a woman who worked at an anti-plague research facility," reports Axios, "but have not confirmed that she contracted plague." On Sept. 25, 28-year-old Daria Shipilova, who worked at an anti-plague research institute in Russia's Irkutsk region, broke a test tube containing the pneumonic plague pathogen, local reports said. Shipilova was admitted to a hospital on Sept. 29 with symptoms of severe pneumonia and died overnight between Oct. 1 and Oct. 2. After her death, authorities imposed quarantines at several medical facilities in the region and placed nearly 200 people who had come into contact with Shipilova under medical observation. Irkutsk Gov. Igor Kobzev said those being monitored showed no signs of illness and had tested negative... Russia's public health agency said Shipilova had "pneumonia of unknown etiology" and that further testing found no microorganisms linked to her work. The agency said the epidemiological situation in the region remains stable. Plague is a potentially life-threatening bacterial disease but can be cured with antibiotics when treated promptly, according to the Centers for Disease Control and Prevention. CNN reports that according to Russian state media agency TASS, it remains unclear exactly what was released: The head of the neighboring republic of Buryatia, Alexei Tsydenov, said earlier that the employee — a 28-year old woman — died "possibly from the plague." He also noted that "there are no plague outbreaks" in Buryatia. The governor of Irkutsk, Igor Kobzev, urged calm on Friday, saying that an extraordinary meeting of the regional anti-epidemic commission was held with Russia's chief state doctor. The meeting was in connection with a "suspected case of a particularly dangerous infection affecting a resident of the region," Kobzev said on Telegram.... The infection in the Irkutsk region is "most likely not the plague, but even if confirmed, there will be no spread of this disease," a previous head of Rospotrebnadzor, Gennady Onishchenko, said on Friday. Onishchenko told the state news agency TASS that the onset of cold weather would likely prevent transmission. Thanks to long-time Slashdot reader schwit1 for sharing the news.

An anonymous reader quotes a report from The Guardian: It is the bane of every fruit bowl: sliced banana that turns brown before it has reached the table. But such woes could soon be a thing of the past, with gene-edited bananas that keep their freshly peeled color now one step closer to reaching British shoppers. According to Tropic, the Norwich-based agricultural-biotechnology company that developed the fruit, the bananas have the same taste and texture but stay "fresh, yellow and appetizing long after peeling and slicing." Gilad Gershon, the chief executive of Tropic, said the flesh of the new banana resisted browning for an extra day or two -- and longer if chilled. He added that the innovation could make it easier to add bananas to prepackaged products such as fruit salads and breakfast pots, as well as reducing waste. [...] Tropic developed the bananas by using a gene-editing technology called Crispr-Cas9 to alter all three copies of a single gene within the fruit. As a result, they were able to reduce the production of polyphenol oxidase, an enzyme that causes browning. A similar approach has been effective in reducing browning in other produce, including mushrooms. Tropic said the non-browning bananas could reduce food waste and CO2-equivalent emissions along the supply chain by more than 25%. "This could support an annual reduction in CO2 emissions of over 9m tonnes in the banana export market alone," the company said. [...] Gershon said Tropic had gained regulatory approval for the non-browning bananas in 10 other countries including Japan, Brazil and the Philippines. The fruit is already being grown in Latin America.
