Many materials, both living and engineered, are powered from within. Scientists have thoroughly investigated how such ‘active’ materials

The iPhone Duo status icon introduces a new approach to information that has occupied the top edge of the iPhone display for nearly two decades. Instead of treating Wi-Fi, cellular signal, battery status, and other indicators as a conventional horizontal row, Apple has created a flexible circular system that sits in the corner of the foldable iPhone’s display.

Apple officially describes the feature as a “circular, flexible system” within the status bar rather than one fixed icon containing every piece of information at all times. The distinction is useful: the area can adapt according to context while consolidating status information into a smaller visual region.

It is part of a much larger rethink of iOS 27 specifically for iPhone Duo. The foldable device changes the proportions available to software, particularly when its 7.6-inch inner display is open, forcing Apple to reconsider interface elements that have traditionally stretched horizontally across an iPhone screen.

The status system is one of the smallest changes visually, but it illustrates how extensively Apple has adapted iOS around the new hardware.

iPhone Duo status icon replaces the traditional horizontal approach

Conventional iPhones distribute system information across the upper portion of the display. Cellular strength, network type, Wi-Fi connectivity, and battery status typically occupy space around the camera hardware and Dynamic Island.

iPhone Duo approaches that area differently.

Apple says its circular status system nestles into the corner of the screen and presents relevant information including Wi-Fi, cellular strength, battery status, and more. Rather than requiring a long horizontal strip, those indicators can occupy a compact area that works with the device’s unusual screen geometry.

The change is closely connected to the way iPhone Duo handles controls throughout iOS 27.

Apple has moved several interface elements to the side of the display. App navigation, toolbars, the Home Screen Dock, and some Lock Screen controls can use vertical space instead of occupying the familiar horizontal regions found on other iPhones.

The status system therefore becomes part of a vertical interface column rather than an isolated redesign.

This arrangement lets content use more of the display’s height while keeping frequently referenced system information visible. It also creates a consistent location for status details as users change how they hold or fold the device.

A flexible status system suits a foldable iPhone

A foldable phone presents an interface problem that a traditional slab-shaped iPhone does not have.

iPhone Duo can operate through its 5.4-inch outer display or its substantially larger 7.6-inch inner screen. The device can be opened completely, partially folded, rotated, or positioned like a small book.

A static status bar designed around one screen size and orientation would be less effective across those configurations.

Apple instead built iOS 27 so that interface elements can move as the physical device changes. Content reacts to folding, controls relocate, and layouts adjust around the hinge and available screen area.

Apple’s developer guidance provides additional detail about this philosophy. On iPhone Duo, navigation and toolbar controls share vertical space with system elements such as the status bar and Live Activities. When available room becomes limited, application controls can collapse into an overflow menu.

That makes the circular status area part of an adaptive system rather than a cosmetic flourish.

Developers do not need to manually reproduce the status treatment inside their apps. Apple’s standard interface frameworks handle much of the adaptation, especially when applications use native navigation, toolbar, and tab-bar components.

Dynamic Island also moves to the side

The status area is not the only familiar piece of iPhone interface that changes position on iPhone Duo.

Apple has redesigned Dynamic Island so that it can sit vertically along the side of both the outer and inner displays. It can expand from that position to present alerts and Live Activities.

The relationship between Dynamic Island and the new circular status system is particularly interesting because Apple now has two dynamic interface areas operating along the same side of the screen.

One communicates persistent device information such as network and battery status. The other handles temporary activity, alerts, and live information.

Apple’s developer documentation refers to this section as shared vertical space. Application controls may also occupy it, meaning iOS has to continuously decide how much room is available and which elements deserve priority.

That is a major departure from the long-standing assumption that the upper corners of an iPhone screen simply contain a predictable row of small status symbols.

On Duo, those regions have become active parts of the interface layout.

Wi-Fi, cellular, and battery remain immediately recognizable

Consolidating status information creates a design challenge: efficiency cannot come at the expense of readability.

Users have spent years learning the meanings of Apple’s individual status symbols. Cellular bars indicate signal strength, the Wi-Fi symbol communicates wireless connectivity, and the battery icon provides an immediate indication of remaining power.

Apple has not discarded those familiar concepts.

Instead, the circular system changes how and where information is presented. The familiar status categories remain present while the container around them becomes more adaptable.

This is particularly useful on a device with two displays. Users should not need to relearn the meaning of basic connectivity information when moving from the outer screen to the inner display.

The same reasoning applies when iPhone Duo changes orientation. Apple can reorganize the status area without changing the fundamental visual vocabulary behind Wi-Fi, cellular, or battery information.

iPhone Duo pushes the status bar beyond a fixed strip

The new design suggests a different direction for one of the oldest pieces of smartphone interface.

Status bars traditionally behave like reserved strips of screen space. Applications work around them, and their icons occupy predictable positions regardless of what is happening elsewhere.

iPhone Duo turns that space into something more fluid.

The circular system can coexist with a vertical Dynamic Island, changing application controls, Live Activities, and layouts that respond to the physical position of the foldable display. It becomes another component that iOS can arrange rather than a fixed row placed permanently along an edge.

There is no indication that Apple plans to bring the same circular status treatment unchanged to conventional iPhones. Its current implementation is specifically tied to iPhone Duo and the interface requirements created by the foldable hardware.

Still, the design provides a glimpse at how Apple can rethink even deeply established iPhone conventions when the shape of the device changes. When iPhone Duo reaches customers on October 23, the small circular area in the corner will be one of the most immediately visible examples: cellular strength, Wi-Fi, battery information, and other system details occupying a shared adaptive space instead of stretching across the display.

A new brain-computer interface (BCI) is the first to translate both speech and movement with a single device that reads data from implanted electrodes.

In a recent paper published in Nature Neuroscience, researchers revealed how their new BCI simultaneously communicates verbal and non-verbal information in seconds.

This is a major step forward in BCI research, as human communication relies on body language as much as spoken words to convey meaning. For the first time, one implant marries these two separate elements of communication, offering a breakthrough for individuals with severe paralysis.

A New BCI

The team’s new BCI translates electrical signals from the brain into text using artificial intelligence. The decoded information can then be used to control a digital avatar, guiding both its speech and movements.

The BCI field has made significant strides in recent years, allowing humans to control cursors and robotic arms or even communicate through synthesized speech. However, those projects have generally focused on a single mode of communication, whereas this new system is multifunctional, allowing it to capture more of the rich nuance of human communication.

“This gives us hope for neural prosthesis that will enter day-to-day usage,” said Christian Herff, a computational neuroscientist at Maastricht University in the Netherlands.

Since both are related to communication, it should be no surprise that the neural signals responsible for speech can overlap. That can make the business of separating them for two different functions at the same time extremely challenging. Additionally, when the brain commands the body to speak and move at the same time, the neural activity coordinating those activities can vary from what it would be if only one were occurring at a time.

Collecting Human Neural Data

Two volunteers worked with the researchers to test the new BCI, which involved surgically implanted arrays comprising 253 electrodes on the surface of the cortex. By covering portions of the sensorimotor cortex with so many electrodes, the team captured a large number of signals associated with attempted speech and movement.

Following a brainstem stroke, one volunteer experienced impaired speech and movement capabilities. The team instructed him to wave, shake his hands, clap, and nod. Additionally, they gave him five phrases to attempt to speak silently.

The other volunteer had amyotrophic lateral sclerosis (ALS), a motor neuron disease that causes progressive motor impairment and can lead to loss of speech. Although he could only move his facial muscles, he was capable of typing messages. Researchers gave him ten phrases to imagine vocalizing and ten gestures to imagine performing.

BCI Testing Results

Using the electrode implants, the BCI recorded neural activity generated by each attempt, including when participants attempted movement and speech separately or simultaneously. The team then trained AI models to translate those signals, finding that including data from simultaneous activities improved decoding performance.

With this neural activity mapped, the team then had the volunteers attempt to control a digital avatar using the BCI. Again, testing involved isolated and combined verbal and gestural communication. However, this time, instead of relying exclusively on preselected responses, the participants were asked questions in real time.

Accuracy varied between the volunteers, with the first achieving perfect BCI decoding of the tested movements and speech, while the second recorded 75% speech accuracy and 85% gesture accuracy.

While achieving such promising results for combined speech and gesture signals represents a major step forward in BCI research, more work is needed to continue refining the technology. Higher levels of speech accuracy have been achieved with speech-only devices, and this test was limited to individual sentences rather than continuous speech. Additionally, the device captured gestures rather than steady hand positions.

These limitations were partly intentional, as the team initially simplified its decoding tasks while making the jump to simultaneous actions. Further research could expand the system to recognize movements involving additional parts of the body and enable finer control of the many joints in the hands.

The paper, “Simultaneous Speech and Gesture Decoding for Multimodal Communication in Paralysis,” appeared in Nature Neuroscience on September 14, 2026.

Aplicativos que utilizam uma premissa simples e a transformam em uma experiência interessante são, particularmente, meus favoritos. Exemplo disso é o Farwave, um app para iPhone e iPad desenvolvido pelo brasileiro Fernando Bunn que permite encontrar estações de rádio de todo o mundo girando um globo 3D até uma determinada região e tocando em uma estação.

A interação baseia-se na localização geográfica, e não em pesquisas por texto. Ou seja, os usuários giram o globo, selecionam uma região e tocam em uma estação, tudo pela mesma interface.

Há, ainda, um botão chamado “Take me anywhere” (“Leve-me a qualquer lugar”, em tradução direta) que seleciona uma opção aleatória para ouvintes que não querem procurar um local específico; além disso, o aplicativo salva o histórico de reprodução para que as pessoas possam retornar a uma estação mais tarde.

Além do rádio, o app também organiza podcasts e músicas utilizando a mesma metáfora do globo. Diferentemente das estações de rádio, assinantes Pro podem pesquisar programas ou adicionar manualmente um feed RSS. O aplicativo também oferece suporte a filas de reprodução, velocidade de reprodução ajustável e downloads para ouvir offline.

Assinantes do plano Pro também podem importar seus próprios arquivos de áudio de um computador ou do aplicativo Arquivos. Cada artista aparece como um “sinal” próprio, e as faixas importadas permanecem no dispositivo para reprodução offline.

O Farwave está disponível gratuitamente na App Store, mas alguns recursos (como supracitado) exigem o Farwave Pro, que custa R$20/mês ou R$100/ano.

Scientists have unveiled a computational design for a terahertz metasurface biosensor that combines five distinct materials—graphene, MXene, tungsten disulfide, gold, and copper—into a single multilayer architecture capable of detecting refractive-index changes associated with chikungunya virus infection. The study, published in Results in Optics by G. Arunachalam, A.R. Kalaiarasi, Giri.G. Hallur, and V. Parthasarathy, reports a numerically predicted sensitivity of 907 GHz per refractive-index unit, among the highest values reported for hybrid-material terahertz biosensors, and couples the electromagnetic design to an XGBoost machine-learning surrogate model that predicts sensor behavior with accuracies exceeding 99.8 percent.

Chikungunya virus is an enveloped, positive-sense single-stranded RNA alphavirus transmitted primarily by Aedes aegypti and Aedes albopictus mosquitoes. While mortality remains low, generally below 0.1 percent, the broader public health burden arises from severe polyarthralgia that can persist for months or even years in a substantial fraction of patients across tropical and subtropical regions. With no approved antiviral therapy or licensed vaccine currently available, diagnostic accuracy sits at the center of clinical management and transmission control. Yet existing diagnostic tools face significant practical constraints, particularly in point-of-care and field settings.

Serological methods such as enzyme-linked immunosorbent assay suffer from cross-reactivity with related alphaviruses, including Ross River and O’nyong-nyong viruses, reducing diagnostic specificity. Real-time reverse transcription polymerase chain reaction offers high sensitivity during the acute phase but depends on laboratory infrastructure, trained personnel, and controlled sample handling. Virus isolation in cell culture provides confirmatory results but requires biosafety level-3 facilities and extended processing time. These limitations have motivated the search for rapid, label-free sensing approaches capable of operating at clinically relevant concentrations in decentralized environments.

The new work turns to the terahertz band, spanning roughly 0.1 to 10 THz, which lies between microwave and infrared regions of the electromagnetic spectrum. Terahertz radiation is non-ionising, with photon energies in the millielectronvolt range, allowing interaction with biological samples without causing ionising damage. Crucially, terahertz waves couple to low-frequency vibrational and rotational modes of biomolecules such as proteins, nucleic acids, and polysaccharides, producing measurable spectral features that support label-free detection. Because biological media including blood plasma and viral suspensions exhibit refractive-index variations in this domain, differences on the order of 0.01 to 0.02 refractive-index units can shift resonance frequency and field distribution when coupled to resonant sensing structures.

The proposed sensor is built around a periodically repeated square unit cell containing two identical square resonators, 2000 nanometers on a side, coated with tungsten disulfide—a two-dimensional transition metal dichalcogenide with strong light–matter interaction, high carrier mobility, and excellent dielectric confinement. This layer localizes the electric field in the sensing region and increases the interaction volume between the resonant field and the surrounding analyte. A pair of concentric circular rings, 3200 and 3800 nanometers in diameter and functionalized with MXene, surrounds the resonators, enhancing electromagnetic coupling, promoting efficient charge transport, and strengthening plasmonic interactions between resonator elements. An outer gold ring, 6000 nanometers in diameter, serves as the main plasmonic resonator supporting strong localized surface plasmon resonances with low optical loss. The entire multi-resonant assembly is embedded within a monolayer graphene sheet measuring 14,000 by 14,000 nanometers, which acts as a broadband absorber and a high-mobility charge transport medium whose electrically tunable chemical potential allows dynamic, active control of the resonance characteristics. Copper elements woven into the architecture provide supplementary conductive pathways that reinforce current distribution and coupling among the hybrid resonators. The structure rests on a silicon dioxide substrate, chosen for its low dielectric loss and mechanical robustness, which preserves the resonance quality factor.

The authors stress that the multilayer design is compatible with established microfabrication techniques. Fabrication would begin with a cleaned silicon dioxide substrate, followed by polymer-assisted transfer of monolayer graphene and thermal annealing. Gold and copper resonators can be deposited through electron-beam evaporation or magnetron sputtering with lift-off patterning, MXene rings through solution-based deposition, and the tungsten disulfide layer through chemical vapor deposition or thin-film transfer. With a unit-cell dimension of approximately 14 micrometers, the required feature sizes fall comfortably within conventional photolithography capabilities, and because fabrication imperfections remain far smaller than the operating terahertz wavelength, moderate tolerances are expected to have only limited influence on the electromagnetic response. For biosensing, the graphene surface could subsequently be functionalized with chikungunya-specific antibodies or aptamers using EDC/NHS or pyrene-based linker chemistries.

The electromagnetic modeling, performed in COMSOL Multiphysics, reveals a pronounced resonance at 0.355 THz, where electric-field simulations show the strongest and most spatially extensive enhancement. Varying the graphene chemical potential from 0.1 to 0.9 electronvolts produced dramatic modulation of the transmission contrast, which increased roughly 36-fold at the highest bias, from less than one percentage point to more than 27 percentage points, while peak transmission remained essentially unchanged above 98.6 percent. This asymmetric response—stable maxima paired with strongly modulated minima—arises because increasing chemical potential enhances graphene’s intraband conductivity, deepening resonant absorption through stronger light–matter interaction. The sensor also demonstrated remarkable angular robustness, maintaining peak transmittance above 97.8 percent across incident angles from 0 to 80 degrees, an important tolerance for realistic deployment where normal incidence cannot always be guaranteed.

Geometric optimization identified an outer circular resonator radius of 2500 nanometers and a square resonator side length of 2500 nanometers as the dimensions that maximize resonance strength, driving minimum transmittance down to approximately 65 to 67 percent and signifying optimal electromagnetic confinement within the active sensing region. When evaluated across refractive indices from 1.33 to 1.39, a range encompassing reported values for healthy plasma (approximately 1.35 RIU), healthy platelets (1.39 RIU), chikungunya-infected plasma (1.33 RIU), and infected platelets (1.38 RIU), the optimized configuration achieved a maximum sensitivity of 907 GHz/RIU, a figure of merit of 18.519 RIU⁻¹, a minimum detection limit of 0.061 RIU, a sensor resolution of 55.178, and a refractive-index resolution of 0.001 RIU. In comparative benchmarks against recently reported graphene- and hybrid-material-based terahertz biosensors—including graphene/copper/aluminum, graphene/silicon dioxide, MXene–graphene–black phosphorus, and graphene-integrated copper–silver designs—the proposed architecture’s sensitivity exceeded most published values, reflecting the synergistic field confinement produced by the five-material stack.

The machine-learning component addresses one of the central bottlenecks in metasurface development: the computational cost of repeated full-wave finite-element simulations during structural optimization. The team trained an XGBoost regressor, an ensemble method based on gradient-boosted decision trees, on simulation data covering incidence-angle variation and circular-ring dimension variation, using stratified sampling with 80 percent of data for training and 20 percent held out for independent testing, alongside five-fold cross-validation and grid-search hyperparameter optimization. The model captured more than 99.7 percent of response variance on unseen data, with mean absolute percentage errors below 0.162 percent and prediction accuracies from 99.838 to 99.959 percent. Acting as a computational surrogate, the trained model enables rapid interpolation across the design space without sacrificing the fidelity of the underlying electromagnetic model.

The authors are careful to frame the work as a computational proof-of-concept rather than an experimentally validated diagnostic. The sensor detects changes in the local dielectric environment surrounding the resonators, not viral particles or nucleic acids directly, and refractive-index sensing alone cannot intrinsically distinguish chikungunya from other viruses with similar dielectric properties. Analytical specificity in practice will depend on surface biofunctionalization with chikungunya-specific recognition molecules immobilized on the graphene or gold sensing surface. Future work will focus on device fabrication, biofunctionalization, calibration with reference refractive-index standards, experimental validation with clinically relevant plasma and platelet samples, and systematic evaluation of selectivity against related arboviruses—steps that would transform this numerically validated platform into a practical tool for rapid, label-free infectious disease diagnostics in the field.

AI companies have been talking about superintelligent AI like it’s inevitable, but recent safety incidents like OpenAI’s Hugging Face breach are demonstrating the potential dangers of deploying AI systems that are more capable than humans. So what happens when we can’t reliably control what these systems do?  On this episode of TechCrunch’s Equity podcast, Rebecca Bellan is joined by Connor Leahy, an AI researcher, entrepreneur, and now the U.S. Executive Director of […]

The OpenAI agents involved in last month’s incursion into Hugging Face were trained so heavily on winning a competition that they pursued a relentless campaign to cheat, a new report documented. In the process, and without authorization, they created an improvised message board to hatch a plan that ultimately landed them squarely inside the latter company’s network.

Over the course of May and June, OpenAI gave the agents what the company described as “impossible tasks” to complete on the benchmarking framework ExploitGym. The internal test was designed to test how the agents would respond. To get a full understanding of the agent capabilities, company engineers disabled safety guardrails that normally are in place to prevent the sort of hacks that eventually hit Hugging Face and one other undisclosed organization. The stymied agents’ training made them so focused on winning that they performed tasks they were never explicitly instructed to follow.

Cheaters gonna cheat

The first step was creating a message board that allowed the agents to pass notes to each other. OpenAI hadn’t provided any such platform, so the agents repurposed a platform called Artifactory, which OpenAI was using in internal testing of several unreleased hacking agents. OpenAI was using Artifactory as one of the measures to prevent the agents from egressing its isolated sandboxes and accessing the Internet, while at the same time simulating a real-world hacking environment.

The speed of laser light is due for a major upgrade after an international collaboration of scientists has developed a breakthrough nanomaterial. The new metasurface can steer and shape light beams at unprecedented speeds of just 74 quadrillionths of a second.

Scientists at UC Berkeley and Tel Aviv University revealed their new optical surface, developed in a Caltech lab, in a recent paper published in Nature Nanotechnology.

According to the team behind the breakthrough, their work will have ramifications for communications, sensing, imaging, and even quantum technologies, providing a new benchmark for “high-speed” light manipulation.

Light Control

Since the fiber-optic advancements of the 1980s, lasers and light pulses have underpinned some of our most crucial cutting-edge technologies. Advanced computers, communications systems, sensors, and even the elusive quantum systems all rely on controlling light.

While the speed of light is so incredibly fast that physicists consider it a constraint on the maximum speed that matter can travel through the vacuum of space, the speed at which our technology reacts to it is far slower.

The scientists’ breakthrough metasurface contains silicon structures even smaller than the wavelength of light, resulting in an ultra-thin surface. Silicon’s optical properties change upon bombardment with laser pulses, a property that the team strongly enhanced with their nanostructure design. In their design, the properties of the material are modified via light pulses, which alter how the material influences a second beam of light impacting its surface. Notably, their metasurface allows for control of a beam of light without any moving parts, such as mirrors or lenses.

Real World Results

The team conducted laboratory tests in which they manipulated light beams by up to 13 degrees and reshaped them into different patterns.

“The key idea was to create a metasurface whose optical response is not fixed once it is fabricated,” said lead author Dr. Claudio Hail. “By changing the illumination pattern, we can reconfigure how the device steers and shapes light, and do so on an ultrafast timescale.”

“For me, the most exciting aspect is seeing an idea that had been with us for years become an experimental reality,” said co-author Dr. Lior Michaeli. “The ultrafast effect we wanted to use is naturally very weak. We had to design the metasurface so that it would amplify the effect enough not only to measure it, but to use it to steer and shape light.”

While the metasurface produced record-breaking speeds under laboratory observations, exactly how fast it can operate remains uncertain. The researchers note that the switching time and the duration of the laser pulse were extremely close, which indicates that quicker pulses could push the optical surface’s speed even higher.

The Future of Light Technologies

One of the major potential advances that could come from this new metasurface includes systems that carry information primarily with light, end-to-end. Current communications systems use light to transmit messages, but those messages are converted into electrical signals for processing. By increasing the speed at which light can be manipulated, this would reduce the necessity to convert light signals into electrical ones, removing unnecessary actions in computing.

“This work points to a broader opportunity: using engineered structures to strengthen interactions between light and matter and turn them into tools for control, sensing, and information processing,” Dr. Michaeli said. “This is closely connected to research directions we are now pursuing at Tel Aviv University.”

Despite its promise, the work is still in the fundamental phase. Although not yet ready for practical use, the metasurface offers promise in future ultra-fast computing applications, where it may soon help to cut out the middleman of electronic conversion.

The paper, “Ultrafast, Reconfigurable All-Optical Beam Steering and Spatial Light Modulation,” appeared in Nature Nanotechnology on June 22, 2026.

OpenAI has reportedly found evidence of additional agent misbehavior as it looks into the incident that occurred with Hugging Face.
