China's Einstein Probe satellite is drawing attention for its unusual wide-field view of the X-ray universe. The spacecraft uses 'lobster eye' optics, a design inspired by how lobsters' eyes reflect light, allowing it to monitor a large swath of the sky at once. That means any sudden, violent X-ray event, such as a supernova or a feeding black hole, is likely to be caught quickly, giving astronomers worldwide rapid alerts to follow up with telescopes.

The American Institute of Physics is spotlighting a new book examining how Einstein's theories are tested against modern experiments and observations. The feature highlights ongoing efforts in physics to probe the limits of relativity, a subject that continues to attract attention as precision measurements and astronomical discoveries challenge and confirm Einstein's ideas.
- 3New 'Atomic Cannon' Experiment Could Test Einstein's Gravity Theory●This “Atomic Cannon” Could Challenge Einstein’s Theory of Gravity
Scientists are highlighting a new experiment, described as an 'atomic cannon', that could put Einstein's theory of gravity to a stringent test. The setup would probe whether general relativity holds under conditions not previously examined, potentially revealing deviations from the century-old theory. Details of the research remain limited in early coverage, but the claim that a laboratory-scale device could challenge one of physics' foundational pillars is drawing wide attention.
