耐热变形虫：在创纪录高温中繁衍生息

A newfound organism thrives in record-breaking heat A TINY AMOEBA has broken a pretty big record. The newly discovered species of single-celled organism can divide and reproduce at a piping hot 63 degrees Celsius (145 degrees Fahrenheit), a higher temperature than possible for any other known complex form of life. The discovery, described in a preprint study on the server bioRxiv and not yet peer-reviewed, “pushes the boundaries of our understanding of life’s limits on Earth and the implications for life beyond Earth—where else and how else life might be able to take hold and thrive,” says microbial ecologist and astrobiologist Luke McKay, who was not involved with the study. …
