A decade after the dairy discovery on strikingly intact remains mummified by the Taklamakan Desert’s arid conditions, scientists have extracted and sequenced DNA from the 3,600-year-old cheese, the oldest in the archaeological record. Fu is director of the ancient DNA laboratory at the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing. The researchers recovered animal and microbe DNA from the kefir cheese discovered on the Tarim Basin mummies. Fu and her colleagues also sequenced the bacterial genes in the ancient kefir cheese, revealing insights into how probiotic bacteria evolved over the past 3,600 years. “Ancient DNA analysis, especially on microbes, is fraught with technical problems, mostly stemming from contamination by modern bacteria,” he added.

☆ China could strike far more than just flattops with its growing arsenal of 'carrier-killer' missiles, defense expert says

In the update, the Pentagon assesses China bolstered its missile stockpiles, specifically its DF-26 supply. The report shows that in 2022, China increased the number of intermediate-range ballistic missiles from 300 in 2021 to 500. "Numbers like that could change the DF-26 from a 'carrier killer' to just a 'ship killer,'" he said. The Pentagon said that in 2020 China "fired anti-ship ballistic missiles against a moving target in the South China Sea, but has not acknowledged doing so." DF-26 missiles attend the military parade in Beijing, capital of China, Sept. 3, 2015.

“Russia’s thinly veiled threats to use nuclear weapons remind the world that escalation of the conflict – by accident, intention, or miscalculation – is a terrible risk. New Construction at Russia's Novaya Zemlya nuclear test site, June 22, 2023. Lop Nur nuclear test site. “The Chinese test site is different than the Russian test site,” Lewis said. Both countries keep their strategic nuclear arsenals on “hair-trigger” alert, meaning that nuclear weapons can be launched on short notice.

☆ China is drilling a hole over 33,000-feet-deep to explore the Earth's crust

China has begun drilling a hole over 10,000 meters (32,808 feet) deep into the Earth's crust. Chinese President Xi Jinping named deep Earth sciences one of four strategic frontiers to explore. The drilling project, led by the country's largest oil producer China National Petroleum Corp., would be among the deepest ever drilled. In a 2021 speech addressing the nation's top scientists, Chinese President Xi Jinping named deep Earth sciences one of four strategic frontiers to explore. The deepest hole is still the Kola Superdeep Borehole in Russia, which reached 12,262 meters (40,230 feet) in 1989 after 20 years of drilling.
