Graphene Sensor Enables Mind Control of Robots, A new Technology

Published

on

technology

Australian researchers have developed a new brain-computer interface (BCI) that utilizes the incredible properties of graphene, a carbon-based material just one atom thick. With funding from Australia’s Defense Innovation Hub, the team at the University of Technology Sydney (UTS) developed an effective “dry” sensor made from silicon and graphene, which can read brain signals and translate them into commands for machines. This breakthrough technology could one day make hands-free and voice-free control of robots possible, without the need for external devices such as keyboards, touchscreens, or hand-gesture recognition.

Current BCIs that translate brain activity into commands for machines are mainly used for medical reasons. For instance, someone with a limb amputation can use a BCI to control a prosthetic with their mind, while individuals with paralysis can use it to “type” words on a computer screen just by thinking about them. However, non-medical applications of BCIs are being explored, such as controlling smartphones with thoughts or even enhancing intelligence by “merging with AI.”

Graphene sensor enables mind to control robots

Evolving Technology

One of the challenges of developing BCIs is the difficulty of reading brain signals without invasive techniques such as implanting tech into the skull. Another challenge is the use of external “wet” sensors, which are covered in gels that can cause skin irritation and have a time limit on how long they can be used. The UTS researchers overcame these limitations by combining the best of graphene, which is very biocompatible and conductive, with the best of silicon technology, making the biosensor very resilient and robust to use.

To test their dry sensors, the researchers built them into a BCI with an augmented reality headset that displayed multiple squares of light, each linked to one of six different commands for a robot dog. The wearer could issue a certain command by concentrating on the corresponding square, and the dry sensors behind their ear read their brain activity and sent the order to the robot dog. The researchers collaborated with the Australian Army to demonstrate the system, and the correct command was issued with an average accuracy of 94%.

The dry sensors were not as accurate as wet ones, but the difference was small enough that the researchers believe the tech would be able to mostly close the gap with more precise sensor placement and pressure in a headset. The potential for this technology is broad and could be implemented in various systems by translating brain waves into zeros and ones. This breakthrough brings us a step closer to noninvasive BCIs for many applications, both on and off the battlefield.

Start Voice Chats Effortlessly with WhatsApp Beta’s New Features

Published

Whatsapp new Feature

WhatsApp, which is trending these days, has brought another new feature to the field. This feature will be for those who are fond of voice messages.
The latest beta version brings interesting improvements to voice group chats, making them more user-friendly and interactive.

According to the details of WaBetaInfo, WhatsApp Beta for Android version 2.24.25.22 is based on the features of the previous version 2.23.24.20, with a focus on better accessibility and user interface.

One notable change in the latest beta update is that a floating action button has been added next to the Send message button. You can now start a voice chat within a group.

The new design will make this process more visible to all group members.

WhatsApp’s latest beta update introduces a handy new feature that makes starting voice chats more intuitive. Now, in a group conversation, you can start a voice chat by simply swiping up. Once the gesture is complete, the voice chat begins, making it easier to connect and engage with others.

The update also expands the availability of voice chats, allowing even small groups or just two people to use the feature. To keep things clean, WhatsApp will automatically close any group that remains inactive or disconnected for 60 minutes. But don’t worry—if a voice chat is already underway, participants can still notify others to join the conversation at any time.

It’s important to note that these features are not yet officially available for public use, and they may take several weeks to roll out.

Elon Musk’s SpaceX and Trump: A Bold Alliance for the Future of Space Travel

Published

on

On Tuesday, the world’s attention was divided between Earth and space. SpaceX’s monumental Starship test launch — heralded as a step toward humanity’s Martian dreams — became an unexpected stage for political theatrics, as President-elect Donald Trump joined SpaceX CEO Elon Musk at the Texas launch site.

While the Starship test showcased unprecedented engineering feats, it was the burgeoning camaraderie between Trump and Musk that stole the spotlight. This improbable duo, united by ambition and outsized personas, reflects a convergence of politics, innovation, and power that could redefine American space exploration and governance.

A Billionaire and a President on the Launchpad

Trump, known for his flair for grand spectacles, arrived in Texas to witness the historic launch of SpaceX’s Starship — the largest rocket ever built. Musk, ever the visionary, explained the rocket’s intricate details, from its massive Super Heavy booster to its ambitious goals of moon landings and Mars colonization. For Trump, this wasn’t just another event. It was a calculated move to align himself with Musk’s genius and SpaceX’s success, both of which resonate with young, tech-savvy voters.

SpaceX Starship

The Starship’s liftoff was awe-inspiring, yet its most anticipated moment — the booster’s dramatic return to the launchpad — ended in an anticlimactic splashdown in the Gulf of Mexico. SpaceX engineers, prioritizing safety, aborted the attempt at the last second. Despite this, the mission achieved critical milestones, including relighting its Raptor engine in orbit and a successful spacecraft splashdown in the Indian Ocean.

Trump’s “Rocket Man” Persona Takes Off

Trump’s association with Musk taps into a new demographic — young, male voters drawn to Musk’s iconoclastic persona. Appearances with Musk add credibility to Trump’s rhetoric of innovation and disruption. The dynamic was on full display at the launch, where Trump’s trademark hyperbole blended seamlessly with Musk’s scientific optimism.

With SpaceX dominating the space industry and Tesla revolutionizing electric vehicles, Musk embodies the success Trump often claims for himself. Their relationship serves mutual interests: Trump gains access to Musk’s tech-driven fanbase, while Musk secures influence in Washington.

The Intersection of Innovation and Politics

This newfound friendship, however, raises questions about conflicts of interest. Musk’s SpaceX holds lucrative contracts with NASA and the Defense Department, while Tesla remains under federal scrutiny for safety and regulatory concerns. Trump’s plans to dismantle government inefficiencies, possibly spearheaded by Musk, could tilt regulatory landscapes to favor Musk’s ventures.

Critics argue that this alliance might prioritize private gain over public interest. Trump’s history of overlooking ethical boundaries only fuels these concerns, as Musk’s growing influence risks consolidating immense power in one individual.

A Rocketship to the Moon—or a Collision Course?

While their partnership is flourishing, the egos of Trump and Musk could eventually clash. Both are used to being the center of attention, and their relationship might not withstand competing ambitions. Yet for now, their collaboration symbolizes a merging of technological ambition and political power.

As SpaceX pushes the boundaries of what’s possible and Trump prepares for his second term, this alliance could herald a new era of American dominance in space. Whether this partnership thrives or falters, one thing is clear: Musk and Trump are reshaping the conversation around innovation, leadership, and the future of space exploration.
