A fundamental goal of physics is to explain the broadest range of phenomena with the fewest underlying principles. Remarkably, seemingly disparate problems often exhibit identical mathematical descriptions.

For instance, the rate of heat flow can be modeled using an equation very similar to that governing the speed of particle diffusion. Another example involves wave equations, which apply to the behavior of both water and sound. Scientists continuously seek such connections, which are rooted in the principle of the “universality” of underlying physical mechanisms.

In a study published in the journal Royal Society Open Science, researchers from Osaka University uncovered an unexpected connection between the equations for defects in a and a well-known formula from electromagnetism.

UC Santa Barbara researchers are working to move cold atom quantum experiments and applications from the laboratory tabletop to chip-based systems, opening new possibilities for sensing, precision timekeeping, quantum computing and fundamental science measurements.

“We’re at the tipping point,” said electrical and computer engineering professor Daniel Blumenthal.

In an invited article that was also selected for the cover of Optica Quantum, Blumenthal, along with graduate student researcher Andrei Isichenko and postdoctoral researcher Nitesh Chauhan, lays out the latest developments and future directions for trapping and cooling the atoms that are fundamental to these experiments—and that will bring them to devices that fit in the palm of your hand.

Recently, a research team found a new way to control the magnetic reversal in a special material called Co3Sn2S2, a Weyl semimetal. The team was led by Prof. Qu Zhe from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, in collaboration with Prof. Liu Enke from the Institute of Physics of the Chinese Academy of Sciences.

“This discovery could help switch the magnetization of devices that rely on ,” said Prof. Qu, “such as hard drives and spin-based technologies.”

The results were published in Materials Today Physics.

Optical atomic clocks have the potential to improve timekeeping and GPS

GPS, or Global Positioning System, is a satellite-based navigation system that provides location and time information anywhere on or near the Earth’s surface. It consists of a network of satellites, ground control stations, and GPS receivers, which are found in a variety of devices such as smartphones, cars, and aircraft. GPS is used for a wide range of applications including navigation, mapping, tracking, and timing, and has an accuracy of about 3 meters (10 feet) in most conditions.

Scientists are tackling one of the biggest hurdles in quantum computing: errors caused by noise and interference. Their solution? A new chip called Ocelot that uses “cat qubits” — a special type of qubit that dramatically reduces errors. Traditional quantum systems require thousands of extra qubits for error correction, but this breakthrough could slash that number by 90%, bringing us closer to practical, powerful quantum computers m.

A study of artificial human and chimpanzee nerve cells revealed how faster-evolving DNA enables neurons to develop increasingly complex brain power.

How did humans evolve brains capable of complex language, civilization, and more?

The answer may lie in exceptional DNA. Scientists at UC San Francisco discovered that certain regions of our chromosomes have evolved at remarkable speeds, giving us an advantage in brain development over apes. However, this rapid evolution may also make us more susceptible to uniquely human brain disorders.

A new source of nitrogen has been discovered. Researchers from RPTU University Kaiserslautern-Landau in southwestern Germany are unraveling the mysteries of a bygone era. As part of ongoing studies, they are investigating how life could have developed on early Earth. Contrary to previous assumptions, biologically available nitrogen does not appear to have been a limiting factor.

Researchers from Osaka University have discovered that the protein subunit AP2A1 may play a role in the unique structural organization of senescent cells.

There are countless products on the market that claim to restore a youthful appearance by reducing wrinkles or tightening the jawline. But what if aging could be reversed at the cellular level? Researchers in Japan may have uncovered a way to do just that.

A recent study published in Cellular Signaling by scientists at Osaka University identifies a key protein that regulates the transition between “young” and “old” cell states.

An international team of researchers has discovered that rifaximin, a commonly prescribed antibiotic for liver disease patients, is contributing to the global rise of a highly resistant strain of vancomycin-resistant Enterococcus faecium (VRE). This superbug, which frequently causes severe infections in hospitalized patients, is becoming increasingly difficult to treat.

The study, published in Nature, reveals that rifaximin use is accelerating resistance to daptomycin—one of the last remaining effective antibiotics against VRE infections.

Led by scientists from the University of Melbourne’s Peter Doherty Institute for Infection and Immunity (Doherty Institute) and Austin Health, the research underscores the urgent need for a more comprehensive understanding of the unintended consequences of antibiotic use. It highlights the critical importance of responsible antibiotic prescribing to mitigate the spread of antimicrobial resistance.

The eye protein rhodopsin of the Greenland shark was found to have amino acid variations that made them more adept at processing blue-light wavelengths – a feature that is advantageous when living in the dim deep ocean waters.

“These genomic analyses offer new insights into the molecular basis of the exceptional longevity of the Greenland shark and highlight potential genetic mechanisms that could inform future research into longevity,” scientists wrote in the study.
