Breakthrough Brings Body-Heat Powered Wearable Devices Closer to Reality
A QUT-led research team has developed an ultra-thin, flexible film that could power next-generation wearable devices using body heat, eliminating the need for batteries.
This technology could also be used to cool electronic chips, helping smartphones and computers run more efficiently.
Professor Zhi-Gang Chen, whose team’s new research was published in the prestigious journal Science , said the breakthrough tackled a major challenge in creating flexible thermoelectric devices that converted body heat into power.
Quantum teleportation has begun to change the world
Quantum teleportation, once confined to the pages of science fiction, is steadily becoming a tangible scientific achievement. Advances in quantum mechanics over the last decade have transformed teleportation from a theoretical concept into an experimental reality.
These breakthroughs have revealed innovative methods for transmitting information instantaneously over vast distances, offering transformative possibilities for computing, communication, and cryptography. Scientists are now closer than ever to bridging the gap between imagination and reality in this cutting-edge field.
At its core, teleportation in the quantum world isn’t about physically transporting objects or people, as popularized by franchises like Star Trek. Instead, it involves transmitting quantum states—essentially the fundamental properties of particles like electrons or photons—without physical movement of the particles themselves.
MIT’s light-activated antiferromagnetic memory could replace today’s ferromagnets
The research team, led by physics professor Nuh Gedik, concentrated on a material called FePS₃, a type of antiferromagnet that transitions to a non-magnetic state at around −247°F. They hypothesized that precisely exciting the vibrations of FePS₃’s atoms with lasers could disrupt its typical antiferromagnetic alignment and induce a new magnetic state.
In conventional magnets (ferromagnets), all atomic spins align in the same direction, making their magnetic field easy to control. In contrast, antiferromagnets have a more complex up-down-up-down spin pattern that cancels out, resulting in zero net magnetization. While this property makes antiferromagnets highly resistant to stray magnetic influences – an advantage for secure data storage – it also creates challenges in intentionally switching them between “0” and “1” states for computing.
Gedik’s innovative laser-driven approach seeks to overcome this obstacle, potentially unlocking antiferromagnets for future high-performance memory and computational technologies.
First demonstration of quantum teleportation over busy Internet cables
Northwestern University engineers are the first to successfully demonstrate quantum teleportation over a fiber optic cable already carrying Internet traffic.
The discovery, published in the journal Optica, introduces the new possibility of combining quantum communication with existing Internet cables — greatly simplifying the infrastructure required for for advanced sensing technologies or quantum computing applications.
Algebraic geometry offers fresh solution to data center energy inefficiency
The manic pace of sharing, storing, securing, and serving data has a manic price—power consumption. To counter this, Virginia Tech mathematicians are leveraging algebraic geometry to target the inefficiencies of data centers.
“We as individuals generate tons of data all the time, not to mention what large companies are producing,” said Gretchen Matthews, mathematics professor and director of the Southwest Virginia node of the Commonwealth Cyber Initiative. “Backing up that data can mean replicating and storing twice or three times as much information if we don’t consider smart alternatives.”
Instead of energy-intensive data replication, Matthews and Hiram Lopez, assistant professor of mathematics, explored using certain algebraic structures to break the information into pieces and spread it out among servers in close proximity to each other. When one server goes down, the algorithm can poll the neighboring servers until it recovers the missing data.
Synchrotron study measures largest magnetic anisotropy of a single molecule
At the Berlin synchrotron radiation source BESSY II, the largest magnetic anisotropy of a single molecule ever measured experimentally has been determined. The larger a molecule’s anisotropy is, the better suited it is as a molecular nanomagnet. Such nanomagnets have a wide range of potential applications, for example, in energy-efficient data storage.
Researchers from the Max Planck Institute for Kohlenforschung (MPI KOFO), the Joint Lab EPR4Energy of the Max Planck Institute for Chemical Energy Conversion (MPI CEC) and the Helmholtz-Zentrum Berlin were involved in the study.
The research involved a bismuth complex synthesized in the group of Josep Cornella (MPI KOFO). This molecule has unique magnetic properties that a team led by Frank Neese (MPI KOFO) recently predicted in theoretical studies. So far, however, all attempts to measure the magnetic properties of the bismuth complex and thus experimentally confirm the theoretical predictions have failed.
Einstein Meets Newton: Scientists Demonstrate New Aspect of Wave-Particle Duality
Linköping University’s experiment confirms a key theoretical link between quantum mechanics and information theory, highlighting future implications for quantum technology and secure communication.
Researchers at Linköping University and their collaborators have successfully confirmed a decade-old theory linking the complementarity principle—a fundamental concept in quantum mechanics—with information theory. Their study, published in the journal Science Advances, provides valuable insights for understanding future quantum communication, metrology, and cryptography.
“Our results have no clear or direct application right now. It’s basic research that lays the foundation for future technologies in quantum information and quantum computers. There’s enormous potential for completely new discoveries in many different research fields,” says Guilherme B Xavier, researcher in quantum communication at Linköping University, Sweden.

Researchers at Flinders University have developed a low-cost, high-density polymer that can store data efficiently using nanoscale indents and can be erased and reused multiple times.
This innovative material, made from sulfur and dicyclopentadiene, promises greater storage capacities compared to traditional storage devices, and its ability to be quickly recycled offers a sustainable alternative for the future of data storage.
