In a study published in Nature Microbiology, Harvard researchers found evidence that viruses infecting microbes in the deep sea interact with a far more diverse set of hosts than previously thought. T...
MIT neuroscientists have found a way to reverse neurodegeneration and other symptoms of Alzheimer’s disease by interfering with an enzyme that is typically overactive in the brains of Alzheimer’s pati...

Across-kingdom partnership between bacteria and fungi can result in the two joining to form a “superorganism” with unusual strength and resilience. It may sound like the stuff of science fiction, but ...
Subtropical gyres are enormous rotating ocean currents that generate sustained circulations in the Earth’s subtropical regions just to the north and south of the equator. These gyres are slow-moving w...
For the first 2 billion years of Earth’s history, there was barely any oxygen in the air. While some microbes were photosynthesizing by the latter part of this period, oxygen had not yet accumulated a...

Much of life on Earth today relies on oxygen to exist, but before oxygen was present on our planet, lifeforms likely used arsenic. The findings of the U.S. National Science Foundation-funded rese...
Deep sea microbes dormant for 100 million years are hungry and ready to multiply（图）

The essential roles microbes play in deep-sea ecosystems are at risk from the potential environmental impacts of mining, a new paper in Limnology and Oceanography reports. The NSF-funded study reviews...
Microorganisms play important roles in the health and protection of coral reefs, but exploring these roles can be difficult because of the lack of unspoiled reef systems throughout the global ocean.An...
