CienciaAIResearchers discovered micro-bryozoan fossils with preserved mineralized skeletons and in-situ soft tissues in early Cambrian strata in Shaanxi, China. This confirms the appearance of bryozoans in the early Cambrian, offering new insights into their origin and mineralization.
CienciaAIResearchers in China have discovered well-preserved micro-bryozoan fossils in the Cambrian strata of Shaanxi Province, providing definitive mineralized skeletal evidence that the phylum originated in the Early Cambrian, pushing back the fossil record by at least 50 million years.
CienciaAIChinese scientist Ma Ping was elected chair of the UNESCO Man and the Biosphere Programme's International Coordinating Council. This marks the second time a Chinese scientist has led the program's highest decision-making body, underscoring China's growing role in global environmental governance.
CienciaAIThe SETI Institute has announced that extensive radio scans of an interstellar comet have revealed no signs of alien technology. The comet, the third known object from another star to enter our solar system, was observed by SETI's telescope in Northern California.
CienciaAIChinese scientists have identified a previously overlooked small peptide gene, dubbed a "heroic" gene, that plays a crucial role in helping crops withstand cold damage. This breakthrough, achieved through eight years of research, utilizes gene editing and AI to enhance crop resilience and safeguard food security against climate change.
CienciaAIA study of the 5300-year-old 'Iceman Ötzi' found ancient and modern microbes, some potentially metabolically active. Researchers identified bacteria and fungi, including cold-adapted yeasts, suggesting some microbes may survive and even thrive under current preservation conditions, though no damage to the remains has been observed.
