**Physicists Debate the Nature of Measurement**
A new paper suggests a reconciliation between the seemingly opposing views of Niels Bohr and John von Neumann on the nature of quantum measurement. This could help resolve a longstanding debate in physics about how to understand the interaction between quantum systems and classical measurement devices.
**Cosmology Faces a Crisis: Two Measures of Universe’s Expansion Disagree**
Two methods used to measure the universe’s expansion rate, the cosmic microwave background and the distance ladder, are yielding incompatible results. This discrepancy, dubbed a “crisis for cosmology,” has scientists scrambling for new physics and exploring alternative models of the universe.
**Rhino Receives Unprecedented Leg Surgery**
Veterinarians at the University of Liverpool successfully treated a broken leg in a juvenile southern white rhino named Amara. This rare procedure, adapted from techniques used on horses, involved keyhole surgery and a long recovery period with a full leg cast. Amara is now back to playing with her rhino companions, offering hope for future treatment of similar injuries in large animals.
**Other Research Highlights:**
* Researchers have developed a new method for protecting working dogs from heat stress: training them to dunk their heads in cool water.
* A breakthrough in understanding the “pseudogap” in quantum physics could lead to the development of room-temperature superconductivity.
* Growing scientific consensus supports global action to combat microplastics pollution.
These are just some of the latest developments in science reported this week. Stay tuned for more exciting discoveries and breakthroughs in the near future.
