The engine combines the right blend of power, performance, technology and efficiency.
A renowned automaker, typically known to introduce high-revving models that often found its competition in offerings from rival brands with double the cylinders, has now taken a bold step by unveiling a single-cylinder engine.

Researchers from the University of Melbourne and RMIT University have invented an experimental wearable device that generates power from a user’s bending finger and can create and store memories, in a promising step towards health monitoring and other technologies.
Multifunctional devices normally require several materials in layers, which involves the time-consuming challenge of stacking nanomaterials with high precision. This innovation features a single nanomaterial incorporated into a stretchable casing fitted to a person’s finger. The nanomaterial enables the device to produce power simply through the user bending their finger. The super-thin material also allows the device to perform memory tasks.
The team, led by RMIT University and the University of Melbourne, in collaboration with other Australian and international institutions, made the proof-of-concept device with the rust of a low-temperature liquid metal called bismuth, which is safe and well suited for wearable applications.
“There is this kind of power the images have. It really isn’t from us. We’re creating the context in which you can appreciate them, but we’re not forcing it,” Kahn said.
In the background, award-winning actress Michelle Williams narrates what we see, which, Kahn admits, was a bit of a deviation from his usual filmmaking blueprint.
“Many of my films are done just through putting together interviews with people or encounters with people,” he said. Or in other words, there is no doctored narrative.
A new “structure reduces the amount of materials necessary – bringing down the weight, volume, and, crucially, the cost of manufacturing.”
In what can provide a major boost to renewable energy generation initiatives, a cutting-edge tidal turbine blade has been indigenously developed in Scotland at a more affordable price.
The turbine was manufactured by a team of design engineers from the University of Edinburgh and is slated to help reduce the levelized cost of tidal energy. The new “structure reduces the amount of materials necessary – bringing down the weight, volume and, crucially, the cost of manufacturing the blade,” said the team in a statement.
Congress is currently debating the FAA’s long-term reauthorization, which might have an impact on the ongoing use of leaded aviation fuel at smaller airports.

Since 1980, the US has had a stunning 99 percent reduction in airborne lead levels as a result of EPA regulations. However, Leaded gas is still used in the aviation industry, according to a report published by EPA on Wednesday.
One problem with a return mission to Neptune is that a flyby focused solely on that world does not provide significant bang for the buck. Without the lucky alignment available to missions in the 1970s and ’80s, we’d have to spend even more fuel to send a probe in that direction, and we wouldn’t get that much more science than we did decades ago.
The next logical step after a successful flyby mission is an orbiter, but the extreme distance to Neptune poses significant challenges. We have no clear way to haul a large enough orbiter to the Neptune system, pack enough fuel to allow it to slow down and do it all in a reasonably short amount of time.
However, researchers have shared a radical new idea for how to overcome these challenges: Use the thin atmosphere of Triton, Neptune’s largest moon, to capture a spacecraft.
Microsoft Research, the R&D arm of the Redmond software giant, is testing the storage of huge amounts of data on glass plates in a futuristic initiative dubbed “Project Silica.” If successful, it could be used to store information for thousands of years without degradation.
The Microsoft researchers store the data in the glass using three-dimensional pixels called voxels. In contrast to classical storage methods such as magnetic spinning disks, the “saucer-sized glass plates of Project Silica will store data for thousands of years and create sustainable storage for the world,” as Microsoft describes it.
Magnetic storage, while widely used, is problematic, according to Microsoft. Because of their limited lifespan, they need to be recopied frequently, which increases energy consumption and operating costs over time: “A hard disk drive might last five years. A tape, well, if you’re brave, it might last ten years”, explains Ant Rowstron, Distinguished Engineer, Project Silica.
“This is real physics, not science fiction”. Two physics experiments showed that it is possible to produce energy inside an energy vacuum.
The quantum energy teleportation protocol was proposed in 2008 and largely ignored. Now two independent experiments have shown that it works.
ABSTRACT. The production mechanism of repeating fast radio bursts (FRBs) is still a mystery, and correlations between burst occurrence times and energies may provide important clues to elucidate it. While time correlation studies of FRBs have been mainly performed using wait time distributions, here we report the results of a correlation function analysis of repeating FRBs in the 2D space of time and energy. We analyse nearly 7,000 bursts reported in the literature for the three most active sources of FRB 20121102A, 20201124A, and 20220912A, and find the following characteristics that are universal in the three sources. A clear power-law signal of the correlation function is seen, extending to the typical burst duration (∼ 10 msec) towards shorter time intervals (Δt). The correlation function indicates that every single burst has about a 10–60 per cent chance of producing an aftershock at a rate decaying by a power law as ∝ (Δt)−p with p = 1.5–2.5, like the Omori–Utsu law of earthquakes. The correlated aftershock rate is stable regardless of source activity changes, and there is no correlation between emitted energy and Δt. We demonstrate that all these properties are quantitatively common to earthquakes, but different from solar flares in many aspects, by applying the same analysis method for the data on these phenomena. These results suggest that repeater FRBs are a phenomenon in which energy stored in rigid neutron star crusts is released by seismic activity. This may provide a new opportunity for future studies to explore the physical properties of the neutron star crust.
Astronomers are one step closer to understanding one of the most enduring solar mysteries, having captured unprecedented data from the sun’s magnetic field.
The groundbreaking data collected from the US National Science Foundation’s (NSF) Daniel K Inouye Solar Telescope (DKIST) in Hawaii—the most powerful solar telescope in the world—has provided the most detailed representations to date of the magnetic field of the so-called ‘quiet’ surface of the sun.
An international team of scientists, including researchers from the University of Sheffield, believe the data has implications for how we model energy transfer between the layers of the sun. The research has been published in Astrophysical Journal Letters.
