New Xreal glasses: virtual screens compatible with nearly all devices

Posted by in categories: augmented reality, entertainment, mobile phones

Xreal is making waves in the world of mixed reality technology, offering a unique approach with its lightweight, almost portable glasses that project virtual screens directly in front of users’ eyes. The latest models, Xreal One and One Pro, come with a game-changing feature that enhances their usability—plug-and-play compatibility with nearly any device equipped with a USB-C video output.

Unlike previous models like the Air 2 Ultra, the Xreal One and One Pro are focused purely on screen mirroring. The glasses can seamlessly display content from an extensive range of devices, including iPhones, Android smartphones, Macs, PCs, and even the Steam Deck. All it takes is a quick connection via USB-C, and you’ll have a massive virtual screen in front of you—perfect for work, gaming, or watching a movie.

The technology behind these glasses relies on micro-OLED displays made by Sony, offering a resolution of 1920 × 1080 per eye. While this doesn’t quite match the ultra-high resolution of Apple’s Vision Pro, it’s worth noting that Xreal’s glasses come at a fraction of the cost—nearly ten times cheaper, in fact.

Beyond the speed of light: The strange particle that could reshape the laws of the Universe

Posted by in categories: particle physics, space

As much as we want to tell Mr Sulu to “Take us to warp factor five”, dangerous causality problems, tricky maths and negative energy could get in the way.

Keith Wiley — The Fermi Paradox, Self-Replicating Probes, Interstellar Transport Bandwidth

Posted by in categories: alien life, existential risks, transportation

It has been widely acknowledged that self-replicating space-probes (SRPs) could explore the galaxy very quickly relative to the age of the galaxy. An obvious implication is that SRPs produced by extraterrestrial civilizations should have arrived in our solar system millions of years ago, and furthermore, that new probes from an ever-arising supply of civilizations ought to be arriving on a constant basis. The lack of observations of such probes underlies a frequently cited variation of the Fermi Paradox. We believe that a predilection for ETI-optimistic theories has deterred consideration of incompatible theories. Notably, SRPs have virtually disappeared from the literature. In this paper, we consider the most common arguments against SRPs and find those arguments lacking. By extension, we find recent models of galactic exploration which explicitly exclude SRPs to be unfairly handicapped and unlikely to represent natural scenarios.
We also consider several other models that seek to explain the Fermi Paradox, most notably percolation theory and two societal-collapse theories. In the former case, we find that it imposes unnatural assumptions which likely render it unrealistic. In the latter case, we present a new theory of interstellar transportation bandwidth which calls into question the validity of societal-collapse theories.
Finally, we offer our thoughts on how to design future SETI programs which take the conclusions of this paper into account to maximize the chance of detection.

Quantum teleportation can survive through busy internet cables

Posted by in categories: internet, quantum physics

An experiment showing that quantum and classical communication can be carried out through the same fibre at the same time may open the door to building a quantum internet with existing infrastructure.

The genetic basis of fertility, family and longevity

Posted by in categories: biotech/medical, genetics, life extension

A new review by researchers from Oxford Population Health and the University of Iceland, published in Nature Aging, reveals how your DNA shapes reproductive health, fertility, and even life expectancy.

Led by researchers from the University of Oxford’s Leverhulme Centre for Demographic Science and the University of Iceland, the review explores how genetic variations can explain differences in reproductive health and longevity.

The study provides the most comprehensive review of male and female genetic discoveries of reproductive traits to date, and provides new insights into how our DNA affects when we have children, the timing of menopause, and even how that is connected to how long we live.

Scientists observe ‘negative time’ in quantum experiments

Posted by in categories: materials, quantum physics

Scientists have long known that light can sometimes appear to exit a material before entering it—an effect dismissed as an illusion caused by how waves are distorted by matter.

Now, researchers at the University of Toronto, through innovative quantum experiments, say they have demonstrated that “negative time” isn’t just a theoretical idea—it exists in a tangible, physical sense, deserving closer scrutiny.

The findings, posted on the preprint server arXiv but not yet published in a peer-reviewed journal, have attracted both global attention and skepticism.

Octopuses and their relatives are a new animal welfare frontier − here’s what scientists know about consciousness in these unique creatures

Posted by in categories: habitats, health, neuroscience

Considering what’s known about their brain structures, sensory systems and learning capacity, it appears that cephalopods as a group may be similar in intelligence to vertebrates as a group. Since many societies have animal welfare standards for mice, rats, chickens and other vertebrates, logic would suggest that there’s an equal case for regulations enforcing humane treatment of cephalopods.

Such rules generally specify that when a species is held in captivity, its housing conditions should support the animal’s welfare and natural behavior. This view has led some U.S. states to outlaw confined cages for egg-laying hens and crates too narrow for pregnant sows to turn around.

China’s Agibot eyes 1,000-humanoid robot army to beat Elon Musk’s Tesla

Posted by in categories: Elon Musk, robotics/AI

A Chinese robotics firm has started mass-producing humanoid robots for general use, while its US counterparts, like Tesla, are aiming for such a feat in 2026.

Agibot, or Zhiyuan Robotics, showcased footage of its manufacturing facility on its official website and revealed that it’s on course to produce 1,000 units by the end of the year, according to a Chinese online news outlet.

OpenAI Confirms New Frontier Models O3 And o3-Mini

Posted by in category: robotics/AI

OpenAI is slowly inviting selected users to test a whole new set of reasoning models named O3 and O3 mini, successors to the o1 and o1-mini models that just entered full release earlier this month.
