Researchers in the US and Canada have detected an effect known as quantum Barkhausen noise for the first time. The effect, which comes about thanks to the cooperative quantum tunnelling of a huge number of magnetic spins, may be the largest macroscopic quantum phenomena yet observed in the laboratory.

 

Search for tiny black holes puts tighter constraints on quantum gravity

New observations of the flavour composition of atmospheric neutrinos have revealed no conclusive evidence for the minuscule, short-lived black holes that have been predicted by some theories of quantum gravity. The study was done by researchers using the IceCube Neutrino Observatory at the South Pole and the result places some of the tightest constraints ever on the nature of quantum gravity.

 

NASA demands new designs for cost-hit Mars Sample Return mission

NASA is seeking alternative designs for its Mars Sample Return (MSR) mission, which is meant to bring back soil and rocks gathered by the agency’s Perseverance rover. But with the MSR beset by cost hikes and delays, NASA concedes that the current design is “too expensive” and that its aim of returning material by 2040 is “unacceptably too long”.

A partnership between NASA and the European Space Agency (ESA), the MSR is designed to return samples collected by Perseverance since 2021 at the Jezera crater on Mars.

 

Looking for dark matter differently

Dark matter makes up about 85 percent of the universe’s total matter, and cosmologists believe it played a major role in the formation of galaxies.

 

Quantum mechanical wormholes fill gaps in black hole entropy

A new theoretical model could solve a 50-year-old puzzle on the entropy of black holes. Developed by physicists in the US, Belgium and Argentina, the model uses the concept of quantum-mechanical wormholes to count the number of quantum microstates within a black hole.
