A technique to measure mechanical motion beyond the quantum limit
Researchers at the University of Colorado have recently developed a new technique to measure mechanical motion using simultaneous electromechanical amplification and cooling processes. Their method, presented in a paper published ...
The measurements of the expansion of the universe don't add up
Physicists use two types of measurements to calculate the expansion rate of the universe, but their results do not coincide, which may make it necessary to update the cosmological model. "It's like trying to thread a cosmic ...

Planet Nine could be a primordial black hole, new research suggests
The hypothetical Planet Nine, assumed to be lurking somewhere in the outskirts of our solar system, may not be a planet at all. A new study, published September 24 on the arXiv pre-print server, suggests that the mysterious ...
New chip poised to enable hand-held microwave imaging
Researchers have developed a new microwave imager chip that could one day enable low-cost handheld microwave imagers, or cameras. Because microwaves can travel through certain opaque objects, the new imagers could be useful ...
