Sony’s Reon Pocket line, launched in 2019, is one of its more unusual tech offerings. It’s a personal cooling gadget worn on the neck and upper back, functioning like a compact, wearable air conditioner. Seven years after its crowdfunding debut in Japan, the company has unveiled the Reon Pocket Pro Plus, its most powerful and efficient model yet.

Peltier-Based Neck Cooling Technology

Unlike typical neck fans, the device works on a different principle that has stayed consistent over time. Reon Pocket Pro Plus cools the skin at the base of the neck using a Peltier-based metal plate. This area is targeted because it’s close to major blood vessels, so cooling it helps lower overall body temperature more effectively.

The update reduces circuit board temperature by 2°C over the Reon Pocket Pro, improving cooling efficiency by 20%. In cold conditions, it can reverse mode to heat the skin via the metal plate.

Adaptive Hold Design Enhances Fit and Stability

The key upgrades in this generation focus on design. Sony has redesigned the flexible neck arms into a sturdier “Adaptive Hold Design” to prevent slipping and keep the cooling plate firmly against the skin during movement or exercise.

The exhaust vent has also been redesigned, letting users adjust both the length and angle of the heat outlet.This directs heat away from the body, improving comfort and allowing use with more clothing, including turtlenecks.

The kit includes the Reon Pocket Tag 2, a redesigned environmental sensor that is 18% smaller than the previous version. It replaces the rear clip with a strap or carabiner so it can attach to a bag or belt, keeping it away from the body for more accurate temperature and humidity readings.

The data is sent to the main device to refine the cooling algorithm, enabling real-time adjustments based on user conditions and the environment.

Battery life remains about 10 hours on the second-highest cooling setting, despite performance upgrades. It also supports a control app but can be used without a phone. It is resistant to sweat and light splashes, but it is not fully waterproof.

The Reon Pocket Pro Plus is available in select European countries (not Portugal) via Sony’s store and Amazon for €229. Interestingly, it is not expected to launch in the United States, unlike earlier versions. It may prove particularly useful as a compact cooling solution during increasingly hot European summers.

NASA unveiled a new Perseverance rover selfie from its Mars exploration since 2021. The image highlights part of the Martian landscape inside the ancient Jezero Crater, featuring rocky terrain and towering cliffs.

NASA said the photo was taken on March 11, marking Perseverance’s 1,797th day on Mars.

Perseverance Reaches Jezero’s Western Edge

Scientists noted that the image documents the rover’s farthest exploration into the western edge beyond Jezero Crater — an area believed to offer important clues about the Red Planet’s ancient history.

Perseverance is exploring an area called “Lac de Charmes.” The rover appears coated in Martian dust. NASA’s Perseverance rover assembled the selfie from 61 separate photos, showing itself next to a newly drilled site while examining some of the oldest rocks found during the mission.

Perseverance Studies Ancient Crater Rim for Signs of Mars’ Past

Recently, Perseverance has been investigating extremely old and scientifically important areas along the crater’s rim.Scientists think these rocks may hold clues to Mars’ ancient crust, past environment, and possible past microbial life.

Since touching down in Jezero Crater in February 2021, the rover has been gathering rock samples for a future return to Earth while looking for signs of past microbial life on the Red Planet.

Wearable technology has advanced significantly with the development of a fabric that efficiently produces electricity from body movement. This innovation could turn everyday clothing into renewable energy sources capable of charging devices without the need for power outlets, marking an important step toward greater sustainability and independence in daily life.

A study from Nanyang Technological University in Singapore explains that the material relies on piezoelectric fibers that transform mechanical pressure into electrical energy. Each movement, such as walking or bending an arm, deforms the polymer within the fabric’s weave, generating a steady current sufficient to power small batteries or health sensors. The fabric also remains effective even after repeated washing in standard machines.

Durable Nanofiber Fabric for Energy-Harvesting Wearables

Its structure combines silver and elastic nanofibers to ensure both electrical conductivity and wearer comfort. What sets this innovation apart is its durability under demanding conditions. Researchers suggest that this technology could eventually lead to smart uniforms capable of tracking vital signs and transmitting data using only the energy produced by human motion.

This material has a wide range of potential applications, from sports to advanced medical monitoring. For instance, athletes could wear clothing that tracks muscle activity while also charging small devices like headphones. It could also power military uniforms to run radios and GPS systems, eliminating the need for heavy lithium batteries.

In healthcare, the fabric may support devices such as external pacemakers or glucose monitors that run continuously without frequent battery replacements. By embedding flexible electronic circuits directly into textile fibers, the limitations of rigid traditional electronics can be overcome. As a result, the technology becomes more seamless and unobtrusive, blending naturally into everyday clothing and improving user comfort.

Sustainability played a key role in motivating researchers to develop this innovative, recyclable fiber. The use of eco-friendly polymers in its production also helps lower the textile industry’s carbon emissions. As a result, replacing disposable chemical batteries with clean energy generated from movement could significantly reduce global electronic waste in the future.

Another important advantage is the material’s durability, as it can endure everyday use without losing its ability to generate electricity. However, the production process still requires refinement to enable large-scale manufacturing and make the product affordable for consumers. Researchers are also increasing the voltage output to enable faster and more efficient smartphone charging.

Partnerships and Safety Approvals Still Needed

Although laboratory results are promising, commercial availability depends on strong partnerships with major clothing brands. Researchers expect early prototypes to appear at technology exhibitions within the next couple of years. In addition, they must obtain electrical safety approval for direct skin contact before mass-producing the material.

Technology firms are already interested in purchasing the patents to develop next-generation fitness accessories. However, the main challenge is standardizing the connectors needed to transfer energy from the fabric to electronic devices. In addition, growing excitement within the scientific community indicates the emergence of a new era in human–machine interaction.

Scientists have found that comet 3I/ATLAS, which drew global scientific interest in 2025, is more than 10 billion years old and may preserve clues about the galaxy’s early history.

The discovery comes from a study published in Nature Astronomy in late April.

Rare Interstellar Visitor Passes Near Earth

Researchers say the comet formed in a region far beyond the solar system. It is only the third known interstellar object to travel through the area of space near Earth.

Scientists used the Atacama Large Millimeter/submillimeter Array telescope in Chile in November last year to study the comet as it moved close to the sun. Scientists expect it to exit the solar system by the end of 2025.

Using observations from the radio telescope, scientists discovered for the first time a hydrogen isotope in an object beyond Earth’s atmosphere.

Unusual Water Composition Found in Comet 3I/ATLAS

They said the data revealed that the amount of deuterium in the water of comet 3I/ATLAS is more than 40 times higher than that found in Earth’s oceans and over 30 times greater than levels measured in comets within the solar system.

This form of water, called deuterated water, differs from ordinary water, which contains two hydrogen atoms and one oxygen atom. In deuterated water, the hydrogen atoms contain an extra neutron, making the water heavier.

The analysis of the environment where the comet formed showed that it was extremely cold — even colder than the solar system during its early development. Scientists estimate the temperature was around -243.14 degrees Celsius.

Researchers believe the comet originated in a protoplanetary disk made of gas and dust orbiting a star, the same type of system in which planets are created.

The radio telescope also played a key role in the study. It allowed scientists to detect particles when the comet made its closest pass to the sun, at a distance of 203 million kilometers. At that point, the ice inside the comet sublimated, releasing gases that could be observed.

Scientists have developed the world’s first nanoparticle nasal spray for stroke, allowing brain drug delivery without surgery or injections. By bypassing the blood-brain barrier, it enables rapid use after symptoms appear, supporting early treatment, protecting brain cells, and reducing complications.

The breakthrough was developed by researchers at The University of Hong Kong’s LKS Faculty of Medicine in collaboration with the InnoHK Advanced Biomedical Instrumentation Centre (ABIC). The team believes the spray could eventually serve as an emergency treatment tool and improve stroke survival and neurological recovery.

Narrow Treatment Window Delays Stroke Care

Ischemic stroke remains one of the world’s leading causes of death and disability. Clot-dissolving drugs and thrombectomy must be given quickly, but limited access, strict criteria, and risks mean over 85% of patients miss timely treatment. Even among those treated successfully, many do not fully recover. As a result, finding fast, safe, and effective early intervention methods continues to be a major global medical challenge.

The research team spent more than 10 years developing the “Nano-in-Micron” technology platform, which later led to the creation of the “NanoPowder” nasal spray.

Aviva Chow Shing-fung said the spray is fast, portable, and easy to use, offering early protection at home or en route to hospital by slowing brain cell death, preserving brain tissue, and buying time for treatment.

Blood-Brain Barrier Limits Drug Effectiveness

According to the professor, more than 90% of central nervous system drugs fail in clinical trials because they are unable to cross the blood-brain barrier, preventing them from reaching the brain and producing therapeutic effects.

To address this problem, the researchers enclosed neuroprotective drugs inside nanoparticles and transformed them into inhalable micrometer-sized powders using particle engineering technology.

The nasal spray functions through four stages: inhalation, deposition, disaggregation, and delivery. After inhalation, the powder dissolves into nanoparticles in nasal mucus, which travel from the nose directly to the brain, bypassing the blood-brain barrier to deliver the drug.

Animal studies showed the spray, used within 30 minutes of stroke, reduced brain damage by over 80% and helped preserve neurological and motor function.

Studies also show the spray may protect the blood-brain barrier, reduce inflammation, and prevent cell death, offering broad brain protection and potentially extending the treatment window.

Nasal Spray Aims to Support Early Stroke Intervention

Shao Zitong said the spray is not a replacement for hospital treatment but an emergency support measure before patients reach the hospital. The aim is to complement existing medical care by reducing brain damage and lowering the risks of death and severe disability through earlier intervention.

Zitong said every second matters in stroke care, as minutes of brain protection can affect recovery. He added the innovation shifts treatment to the pre-hospital stage, enabling early neuroprotection instead of relying only on hospital-based clot removal.

The team is conducting toxicology tests and clinical trials to bring a nasal spray to pharmacies and communities as an emergency stroke treatment. They hope it can serve as a frontline defense during the critical early stages of a stroke. The scientists are consulting emergency doctors and neurologists to ensure the treatment works in real-world medical settings.

Researchers said the “Nano-in-Micron” platform could also deliver small-molecule drugs, biologics, and traditional medicines, and may be adapted to treat neurological and neurodegenerative diseases such as Alzheimer’s, motor neuron disease, and meningitis.

“We gave AI a body.” It’s the kind of statement that feels equally bold and disturbing—exactly the sort of idea you’d expect from a William Gibson story. Except this is real. Built by a six-person team, Human Operator won the “Learn Track” at the MIT Hard Mode 2026 hackathon. [2, 3] The project uses electrical stimulation to let an AI temporarily control a person’s arm to teach physical skills.

During a frantic 48-hour sprint at the MIT Media Lab, the team created a device that blurs the boundary between person and machine. [2, 3] Rather than making another conversational AI, they set out to experiment with the future of “intelligent physical systems.” The result is Human Operator—a fascinating, slightly unnerving glimpse into human augmentation that challenges our assumptions about control and autonomy.

A Clever DIY Fusion of AI and Human Motion

Technically, the project is an impressive example of creative DIY engineering. Instead of relying on groundbreaking hardware, the team combined accessible components in an inventive way to produce something entirely new. [2] The setup begins with a camera for visual input and a microphone that captures spoken instructions from the user—or perhaps from the user’s “controller.”

All of that information is routed to the system’s central intelligence: Anthropic’s Claude API. The AI interprets the request, analyzes visual data, and determines the required muscle movements, which are sent to an Arduino-based system that bridges the AI and the human body.

How AI Uses Electrical Pulses to Control Movement

The most critical stage is the use of Electrical Muscle Stimulation (EMS). Electrodes attached to the user’s forearm deliver carefully timed electrical pulses that trigger specific muscle contractions, guiding the movement of the hand and wrist according to the AI’s commands. [2] Say “play piano,” and the AI responds by orchestrating tiny shocks that move your fingers across the keys.

During the hackathon, the team showcased the Human Operator completing several tasks with surprisingly convincing results. The system successfully directed a user’s hand to wave, form a precise “OK” gesture, and even play an unfamiliar tune on the piano. Watching the footage feels uncanny—the movements are genuine, yet the person appears to have little control over their own arm.

The project’s demo video openly embraces the oddness of the experience, calling it a “bizarre and fascinating cocktail.” That description fits a technology that is both astonishing and unsettling, hinting at a future where humans become extensions of AI systems.

What makes Human Operator especially fascinating is that the technologies behind it are not experimental at all. Electrical Muscle Stimulation (EMS), or neuromuscular electrical stimulation (NMES), has long been used in physiotherapy and athletic training to rehabilitate and strengthen muscles. The ability to trigger involuntary muscle movement through electrical impulses is already a well-established technique.

Created by Peter He, Ashley Neall, Valdemar Danry, Daniel Kaijzer, Yutong Wu, and Sean Lewis, the project stands out for its integration of existing tools. [1, 2, 3, 4] It combines an AI model, a microcontroller, and biohacking techniques into a functional cybernetic system. Together, these components create something far more impactful than their individual parts alone. The project’s details, including its open-source code, are available online through its Devpost and GitHub pages.

Human-AI Collaboration Raises New Ethical Questions

That said, this 48-hour hackathon experiment is not about to transform humanity into AI-controlled puppets overnight. Still, it raises a wide range of possibilities—and ethical concerns. Research into Human-Autonomy Teaming (HAT), which studies collaboration between people and intelligent systems, has been growing steadily. [6, 7] Human Operator represents one of the most literal interpretations of that concept so far.

The potential applications are remarkable. An AI system like this could help people learn physical skills—from surgery to music—by guiding their movements. It could also become a powerful accessibility tool, assisting individuals with limited motor function in completing everyday activities.

At the same time, the darker implications are impossible to ignore. Issues surrounding autonomy, consent, accountability, and cybersecurity immediately come into play. What happens when a system like this connects to the internet? Who bears responsibility if an AI-directed movement causes harm? These questions may still sound theoretical, but Human Operator makes them feel suddenly immediate and real. For now, the project remains a provocative experiment, hinting that AI’s future may extend beyond software into its relationship with the human body.

Amid growing interest in AI workplace tools, Lenovo unveiled its AI Workmate Concept at the Mobile World Congress, giving office chatbots a physical form with a face and built-in projector.

The compact desktop robot has a 3.4-inch LCD “face,” cameras, and a Pico projector on a movable arm. It responds to voice and gestures, recognizes handwritten notes, and can access workplace files and communications to answer questions in real time.

Voice Interaction, Expressive Display, and Document Projection

The robot communicates using a synthesized voice, while the screen mainly displays animated facial expressions. Its cameras can capture handwritten notes for presentations, while the built-in projector displays documents and slides on a desk or wall. Lenovo demonstrates the concept in a somewhat quirky promotional video.

It’s hard to imagine the Workmate fitting seamlessly into daily office life, especially given concerns about sensitive data access and AI accuracy. Still, Lenovo says it runs AI models locally rather than in the cloud, and one demo showed it capturing a handwritten signature to digitally sign a document in real time.

The concept isn’t the worst AI hardware idea we’ve seen, but its value depends on how reliably its local AI can understand data and avoid mistakes. It also raises the question of whether this needs to be dedicated hardware at all instead of software on existing devices. Features like the cameras, projector, and especially the animated LCD face don’t necessarily make day-to-day work significantly easier.

Scaling Challenges and Enterprise Adoption Barriers

Another challenge is adoption at scale. Convincing companies with hundreds or thousands of employees to deploy a product like this is no small task. Enterprise tools need to prove they’re secure, easy to maintain, and cost-effective over the long term. Unless it becomes essential, IT departments are unlikely to embrace another device to manage and support.

For now, Lenovo is only presenting the Workmate as a concept and hasn’t shared any plans for commercialization or pricing.It’s unlikely to become common anytime soon unless it proves as useful as company-issued laptops or smartphones.

Engineers have spent years exploring alternatives to the traditional computer mouse, creating designs that are pen-shaped, flat, and even ring-shaped. Just when mouse designs seemed exhausted, UK startup NextAxis Design introduced an egg-shaped mouse called Ovo on Kickstarter.

Ovo weighs 98 grams (3.5 oz) and measures 48 × 61 mm (1.9 × 2.4 inches). Designed to rest naturally in the palm, it aims to encourage more ergonomic hand positioning and smoother movement. The device works in the air or on a mouse pad, both designed to reduce wrist strain. Its unconventional design may require a learning curve, which could be one of its biggest drawbacks.

Unlike a standard mouse, Ovo doesn’t rely on sliding across a surface. Instead, it tracks hand movement in 3D space, moving the cursor through tilting and rotating instead of dragging. It also includes familiar functions like clicking and scrolling.

Broad Compatibility and Advanced Customization Features

The device requires no drivers and works wirelessly across major operating systems, including Windows, macOS, Linux, Android, and iOS. It can pair with multiple devices through Bluetooth or Wi-Fi and is also designed to integrate with smart home systems.

A major highlight of the device is its customization options.Users can adjust sensitivity, create macros and gestures, and set custom profiles for different workflows. Its two-shell design assigns tapping and cursor control to the upper half and swiping and scrolling to the lower half.

The mouse is designed to deliver steady and accurate cursor control, making it suitable for tasks such as 3D manipulation, presentations, and creative design applications. For instance, video editors may find it more convenient to move through timelines using smooth rotational gestures rather than the conventional drag-and-drop actions required by a standard mouse.

Although Ovo offers the same core functionality as a conventional mouse, its creators admit that it may not completely replace traditional models for every type of workflow. Since it is mainly intended as a pointing device, users performing highly precise tasks may still prefer a standard mouse in certain situations.

Long Battery Life, Wireless Charging, and Kickstarter Launch Details

Ovo is powered by a rechargeable battery that reportedly delivers up to 80 hours of usage on a single charge. It supports both wireless charging and USB-C charging, features a glossy polymer exterior, and comes in black, white, and orange color options.

The device is currently available on Kickstarter at an early-backer price of US$109, while the expected retail price is set at $199. The package includes the Ovo mouse, a USB-C cable, and a charging pad. If the crowdfunding campaign meets its goals, shipping is expected to start in December.

For centuries, medicine has tried to manage pain by reducing symptoms or blocking nerve signals. Now, researchers are adopting a more radical approach: they are preventing pain before the brain becomes aware of it. Importantly, this work is already being tested in laboratories developing real-time neural technologies, not just remaining theoretical.

Traditionally, pain treatment has focused on reducing inflammation, broadly blocking nerves, or changing how the brain interprets signals through strong drugs. These methods often come with major drawbacks, including dependence on medication and unintended loss of sensation elsewhere in the body.

Recent experimental studies are now suggesting a different strategy.

Targeting Ion Channels to Interrupt Pain Signals at the Source

At the University of Oxford, neurologist David Bennett’s team has developed a method that targets ion channels in sensory neurons. These channels act like tiny electrical gateways that transmit nerve signals. When tissue is injured or inflamed, they transmit pain signals to the brain. The researchers genetically modify specific nerve cells so they can be activated or deactivated with a safe, targeted chemical. When activated, the system weakens pain signals before they fully travel through the nervous system, surprising the researchers involved.

In simple terms, the pain never makes it to the brain.

What makes this especially significant is its precision. Instead of numbing large areas like traditional anesthesia, the method targets only the neurons involved in the injury. This could be a major breakthrough for treating neuropathic pain, particularly in conditions such as diabetes or long-term nerve damage.

Although the research is still at an early, laboratory stage, the findings are already supporting a once-unthinkable possibility: highly personalized therapies that can block pain with near surgical accuracy.

At the same time, a research team in the United States is pursuing a similarly remarkable—and potentially even more futuristic—approach.

At the University of Washington, scientist Robert Gereau is working with optogenetics, a field that merges genetics with light-based stimulation to regulate neuron activity.

The method sounds almost like science fiction. Scientists insert light-sensitive proteins into selected nerve cells, and then use a device that delivers brief flashes of light to instantly switch those cells on or off.

Optogenetic Testing Shows Rapid Pain Interruption in Rat Models

In experiments so far, researchers have tested the system in rats with interstitial cystitis, a highly painful bladder condition. The device picked up pain-related signals and immediately delivered light pulses that disrupted the nerve activity responsible for the pain.

The effect was nearly instantaneous.

Researchers suggest that, in the future, doctors could implant similar devices in humans and control them through mobile apps. For complex conditions such as endometriosis or chronic pelvic pain, the aim would be to intercept pain signals at key points in the nervous system before they can spread further.

However, major challenges remain, including proving safety, durability, and effectiveness in humans. Even so, the studies suggest medicine is starting to view pain as a controllable biological signal rather than something to simply endure.

The Wider Impact of Chronic Pain

The implications extend well beyond physical relief. Chronic pain affects millions of people worldwide and contributes to anxiety, depression, reduced quality of life, and financial strain.

As a result, managing pain signals as easily as muting a notification marks a profound shift in how medicine may treat human suffering.

This research is still in its early stages, but it is edging closer to something once considered purely theoretical: the ability to shut down pain with near-instant accuracy.

And perhaps most striking of all is the possibility that the brain might never even register it at all.

Scientists have created organoids that regenerate in a way similar to the endometrium — the uterine lining that renews itself during every menstrual cycle.

Detailed in the journal Cell Stem Cell, the discovery enables researchers to study in the lab a rare form of tissue repair seen in humans and could support future treatments for wound healing and regenerative medicine.

The endometrium is remarkable for its ability to repair itself after menstruation without forming scars. How this process works remains a scientific mystery, according to molecular biologist Konstantina Nikolakopoulou of the Friedrich Miescher Institute for Biomedical Research in Basel, who led the research.

Lab-Grown Organoids Replicate the Menstrual Cycle

According to the Nature portal, Nikolakopoulou’s team developed 3D structures using human endometrial epithelial cells. These hollow organoids mirrored the behavior of uterine tissue by responding to hormones and undergoing stages similar to the menstrual cycle.

To recreate the cycle, researchers exposed the organoids to estrogen and progesterone before withdrawing the hormones, imitating the natural progesterone drop that initiates menstruation. After mechanical damage, the tissue was able to regenerate on its own.

The current organoids remain relatively simple, consisting only of epithelial cells. Nikolakopoulou noted that understanding these core mechanisms is an essential first step before making the model more advanced by adding other cell types, including immune, endothelial, and stromal cells.

Scientists Say the Model Could Transform Endometriosis Research

Evolutionary biologist Deena Emera from the Buck Institute for Research on Aging in California praised the breakthrough, saying the model provides a unique way to investigate endometrial regeneration and may improve understanding of conditions such as Endometriosis.

Earlier research in primates indicated that deep stem cells were mainly responsible for renewing the endometrium. However, the new study also found a role for luminal cells — surface cells that help embryos implant during pregnancy.

The findings challenge long-standing ideas about how the uterus regenerates. Researchers say the model could eventually be used to test treatments and therapies focused on women’s reproductive health and may also guide advances in regenerative medicine.

By enabling scientists to watch tissue break down and regenerate in real time, the study offers a rare glimpse into how the human body heals without forming scars. The development of the organoid marks both a scientific and technological milestone for researchers.
