A zero-day vulnerability dubbed “StyleSmuggler” affecting all versions of Magento and Adobe Commerce is being exploited in attacks to deploy a backdoor.
The first exploitation incident was recorded on September 4 on a target running the latest security updates.
E-commerce security company Sansec says that Adobe Enterprise Support confirmed earlier today that it was working on a fix but did not provide a timeline for its release.
Direct measurements of diamond melting under extreme pressure resolved a long-standing theory-experiment mismatch and could improve both fusion research and planetary models.
Diamond is not only a gemstone. This exceptionally hard form of carbon is also used in the tiny capsules that surround fuel in inertial confinement fusion experiments, and researchers think carbon may form diamonds that fall through the interiors of ice giants such as Neptune and Uranus.
Both environments expose diamond to immense pressure, yet experiments and computer simulations have long produced conflicting descriptions of what happens to the material under such extreme conditions.
Researchers at Lund University have developed a new type of light-emitting diode based on thin, branched nanowires that could offer significantly higher efficiency and lower production costs than current technology. By controlling where in the structure the light is generated, the researchers have reduced the losses that would otherwise limit the amount of light that can be used. Their study is published in the journal Nano Research.
In materials used for conventional light-emitting diodes—such as the LED bulbs found in most households—a large proportion of the light is trapped inside the material because of what is known as total internal reflection. This phenomenon means that only a small proportion of the light comes out, even though it is generated inside the material.
The new design aims to overcome this problem. The method is based on the fact that light is emitted from very thin side branches that extend from a central nanowire. If the structures are made thin enough—thinner than the wavelength of light—the light cannot be trapped inside the material in the same way.
The field of silicon photonics, which uses light rather than electricity to transmit and process data on semiconductor chips, has enabled optical systems to evolve from bulky setups to compact, advanced systems. Typically, however, these silicon-photonics chips are rigid and opaque.
MIT scientists have now figured out a scalable way to make silicon-photonics chips flexible and transparent, opening a route to advanced microchips that could be used in applications such as discrete health monitors that conform to the body or transparent augmented-reality displays that fit the curve of a pilot’s helmet.
While scientists have recently performed lab demonstrations of chips that were flexible or transparent, they could only fabricate a few devices at a time.
Researchers from MIT have designed a new qubit architecture that enables qubits to interact with each other much more quickly while remaining very stable. This advance could someday help scientists build practical quantum computers that can run long, complex algorithms with high accuracy.
Qubits, which are the building blocks of a quantum computer, usually only store data and rely on other electronics to perform operations and communicate. But qubits are so fragile and error-prone that it is difficult for scientists to connect enough qubits before they lose their information and need to be reset.
The MIT team designed a dual-purpose qubit with two separate parts: one component that stores data and one component that interacts with other qubits and electronics. This design improves the reliability of the qubit and enables it to operate with a reduced error rate, so it can perform more computations in the same time span.
The hidden world of quantum mechanics exists at scales many orders of magnitude smaller than living organisms, yet scientists have long theorized that quantum effects play an important role in biology. Birds’ ability to sense magnetic fields during migration is one of the best-known mysteries in this field, with leading theories suggesting that this sensing could be achieved by exploiting quantum entanglement.
By proving a mathematical principle about how best to control quantum systems, researchers at the Okinawa Institute of Science and Technology (OIST) have taken what could be the penultimate step toward finally putting this avian hypothesis to the test, while also unlocking new biological platforms for quantum computing. Their results are published in the journal Quantum.
Ugur Abdulla, head of the Analysis and Partial Differential Equations Unit at OIST, explains, “Many researchers have studied quantum effects and their role in biology, though it isn’t always easy to translate an idea or hypothesis into a laboratory experiment. We hope that by laying the mathematical foundation for controlling quantum phenomena, we can bring some of these ideas from quantum biology out of the theoretical realm and into the lab.”
Using an engineered metasurface that traps light, Cornell researchers have demonstrated a new way to generate strong static magnetic fields without using external magnets or magnetic materials—an approach that could advance spintronics, quantum and photonic computing, and data storage.
In an article published in Advanced Science, Shivaksh Rawat, a Ph.D. candidate working with Gennady Shvets, the J. Preston Levis Professor of Engineering in the School of Applied and Engineering Physics, and Samyobrata Mukherjee, a postdoc in the same group, described how a new technique for light manipulation—the so-called “time interface”—can be used to convert part of an optical wave’s energy into static magnetization.
When a light wave experiences a spatial interface—for example, when it travels through air and then water—some of the light is reflected off the surface while the rest is transmitted through it. Similarly, when a light wave experiences a time interface—a sudden change in the optical properties of the propagation medium, such as an increase or decrease in the refractive index—it also produces reflected and transmitted waves.
