Classical physics can explain quantum weirdness, study shows

When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it falls, and when and where it will land. But if you were to squeeze that same ball down to the size of an atom or smaller, it would behave in ways beyond anything that classical physics can predict.

Or so we’ve thought.

MIT scientists have now shown that certain mathematical ideas from everyday classical physics can be used to describe the often weird and nonintuitive behavior that occurs at the quantum, subatomic scale.

Particle thought to break physics followed rules all along, research reveals

A tiny discrepancy in particle physics has loomed for decades as an exciting possible crack in one of science’s most successful theories, hinting at unknown forces or quantum objects. Now, an international team led by a Penn State physicist has published the most precise study yet to reveal the discrepancy was a fluke in calculation, not nature.

More than half a century of measurements of a fundamental property of the muon—the more massive, short-lived cousin of the electron—did not line up with theoretical predictions, raising hopes that new physics might be behind the unexplained inconsistency.

In a paper published in the journal Nature, a team led by a Penn State researcher describes one of the most precise calculations ever performed in particle physics, showing that the Standard Model—the theory describing the known building blocks of matter—still holds.

Laser-plasma ‘mirror’ unlocks a new path to extreme light intensities

An international team of physicists has achieved a significant advance in laser science, demonstrating for the first time a practical route to dramatically boosting the intensity of high-power laser light.

The results, published in Nature, could unlock the route towards creating the most intense light ever produced in a laboratory, opening the door to experiments that probe the fundamental laws of physics by directly interacting light with the quantum vacuum.

The work was led by Professor Peter Norreys and Dr. Robin Timmis at the University of Oxford, working in close collaboration with Professor Brendan Dromey and Dr. Mark Yeung at Queen’s University Belfast, and scientists from the Science and Technology Facilities Council’s Central Laser Facility (CLF).

Quantum simulations that bypass resolution limits offer insights into high-temperature superconductivity

A new method developed at LMU overcomes fundamental resolution limits and may provide insights into high-temperature superconductivity. Physicist Dr. Sebastian Paeckel has developed a method that can be used to calculate spectral functions of complex quantum systems much more precisely than was possible previously. His approach reconstructs precise energy spectra without requiring lengthy calculations.

This reveals previously hidden details, as Paeckel reports in the journal Physical Review Letters. He conducts research at the Faculty of Physics at LMU and at the Munich Center for Quantum Science and Technology (MCQST).

Do decoherence, gravity, dark matter and dark energy all originate from quantum corrections?

Only about 5% of the universe is composed of normal matter that we can directly observe, while the remaining 95% is widely believed to consist of dark matter and dark energy. Paradoxically, however, the nature of these dark components remains unknown. Is this due to limitations in our observational capabilities, or does it reflect a more fundamental incompleteness in the classical laws of physics that have long underpinned our understanding of the universe?

In a recent study published in the International Journal of Modern Physics D, I proposed that dark matter and dark energy may not correspond to physically existing substances, but could instead emerge as effective phenomena arising from the quantum nature of gravity.

Soundwaves settle debate about elusive quantum particle

It was a head-spinning discovery. In 2018, researchers in Japan claimed to find concrete evidence of an elusive particle, a Majorana fermion, in a quantum spin liquid called ruthenium trichloride. Majoranas are highly sought-after by quantum materials scientists because when a pair are localized, or trapped, they can securely encode information and form a stable qubit—the building block of quantum computing.

Some researchers heralded the finding and used it to launch their own studies, while others believed the breakthrough—which was made by measuring what’s called the thermal Hall effect—was actually a mirage caused by defects in the material sample.

Cornell researchers have now waded into the debate and their findings, published in Nature, show both camps were wrong. By measuring the movement of sound waves rather than the flow of heat, the team discovered the thermal Hall effect was caused by rotating lattice vibrations called chiral phonons.

Why does life prefer one ‘hand’ over the other? New study points to electron spin

A team of scientists has identified a new physical mechanism that could help explain one of the most persistent mysteries in science: why life consistently uses one “handed” version of its molecules and not the other. In a new study led by Prof. Yossi Paltiel of the Center for Nanoscience and Nanotechnology at Hebrew University and Prof. Ron Naaman of the Weizmann Institute, researchers show that electron spin, a fundamental quantum property, can cause mirror-image molecules to behave differently during dynamic processes, even though they are otherwise identical. The work appears in Science Advances.

Many molecules essential to life come in two mirror-image forms, known as enantiomers. Chemically, these forms are nearly indistinguishable. Yet in living systems, only one version is typically used: amino acids are almost exclusively one type, while sugars follow the opposite pattern.

This phenomenon, known as homochirality, has puzzled scientists for more than a century. Existing explanations have struggled to account for why one specific version was selected globally.

Kyber ransomware gang toys with post-quantum encryption on Windows

A new Kyber ransomware operation is targeting Windows systems and VMware ESXi endpoints in recent attacks, with one variant implementing Kyber1024 post-quantum encryption.

Cybersecurity firm Rapid7 retrieved and analyzed two distinct Kyber variants in March 2026 during an incident response. Both variants were deployed on the same network, with one targeting VMware ESXi and the other focusing on Windows file servers.

“The ESXi variant is specifically built for VMware environments, with capabilities for datastore encryption, optional virtual machine termination, and defacement of management interfaces,” explains Rapid7.
