New chip-scale gyroscope measures rotation with unprecedented sensitivity
来源: Phys.org - latest science and technology news stories · 发布于
Researchers have developed a chip-scale optical ring-laser gyroscope that can measure rotation as slow as 37 degrees per hour. This record sensitivity, approaching Earth's rotation rate of 15 degrees per hour, could eventually be useful for precision navigation and orientation sy
Researchers have developed a chip-scale optical ring-laser gyroscope that can measure rotation as slow as 37 degrees per hour. This record sensitivity, approaching Earth's rotation rate of 15 degrees per hour, could eventually be useful for precision navigation and orientation systems, particularly where GPS is unavailable.

Urbanization takes a bigger toll on bird diversity in the tropics than it does at other latitudes, study finds
Researchers at McGill University have found that urbanization is weakening one of Earth's most enduring ecological patterns: the tendency for biodiversity to increase toward the tropics, a pattern known as the latitudinal diversity gradient.

Mollusk family trees play a key role in shaping microbiomes, researchers find
A mollusk's microbial community has more to do with its family tree than its address. In other words, the composition of a mollusk's microbiome depends less on the environment in which it lives and more on what species it belongs to, say University of Michigan researchers.
