In this illustration of the superconducting material Eu-1144, the blue and magenta wave shown above the crystal lattice represents how the energy level of the electron pairs (yellow spheres) spatially modulates as these electrons move through the crystal.

ENGLEWOOD — Amid a raging statewide debate over housing availability and affordability, a small city on Denver’s southern doorstep has taken the fight to a whole new level of discord: throw the bums out. A group of citizens is targeting more than half of the seven-member Englewood City Council for ouster, citing the elected leaders’ support of “high-density housing projects negatively impacting adjacent neighborhoods,” according to recall petitions filed with the city. They also accuse the four council members — Mayor…

A new study suggests that individuals with low bone density may face a higher risk of developing dementia, though it only establishes an association and not causation between the two conditions.According to a study recently published in the online issue of Neurology – the medical journal of the American Academy of Neurology – individuals with low bone density may face a greater risk of developing dementia in comparison to those with high bone density. It’s important to note that the study only establishes a correlation…

There are three forces acting on the debris. First, there's the downward-pulling gravitational force (Fg) due to the interaction with the Earth. This force depends on both the mass (m) of the object and the gravitational field (g = 9.8 newtons per kilogram on Earth).Next, we have the buoyancy force (Fb). When an object is submerged in water (or any fluid), there is an upward-pushing force from the surrounding water. The magnitude of this force is equal to the weight of the water displaced, such that it's proportional to…

This image shows the positions of atoms (blue spheres) that make up the crystal lattice of a copper-oxide superconductor, superimposed on a map of electronic charge distribution (yellow is high charge density, dark spots are low) in charge-ordered states. Normally, the atoms can vibrate side-to-side (shadows represent average locations when vibrating). But when cooled to the point where the ladder-like charge density wave appears, the atomic positions shift along the “rungs” and the vibrations cease, locking the atoms in…

An entry by Gresley Abas Architects (WA) to the Density Diversity Done Well competition (State of Queensland 2019). Credit: Australian Planner (2023). DOI: 10.1080/07293682.2023.2183225 James Cook University researchers say better planning is needed to ensure more sustainable and affordable higher density housing, such as units and apartments, is built in regional centers. …

Lithium batteries started an avalanche of innovation when they became widely available, largely because they could hold significantly more energy by weight than other contemporary chemistries. Touchscreen smartphones, drones, all-day laptops, long-range electric cars and the first generation of battery-powered aircraft were some of the results.But more energy storage is always better – you can either make things last longer, or weigh less – and manufacturers have been racing to raise the bar with next-gen battery…

Astronomers have just found a cosmic cannonball.Around a star some 730 light-years away orbits an exoplanet the size of Jupiter, but with a density that boggles the mind. Astronomers have determined that the world, named TOI-4603b, has a mass of nearly 13 Jupiters.That means it's nearly 3 times the density of Earth, and just over 9 times the density of Jupiter. And it's really cuddly with its star, with a tight orbit of just 7.25 days.This places it in a small but significant category of worlds that defy our…

HONOR announced three new smartphones yesterday, the Magic5, Magic5 Pro, and the Magic Vs. All of those are global devices announced at MWC 2023. That being said, HONOR also announced the very first silicon-carbon battery with higher energy density during that event.HONOR has introduced the very first silicon-carbon battery which offers higher energy densityThe announcement of that battery kind of flew under the radar, as there was plenty to say during the event. It did not get the attention it needs, which is why we’re…

Most smartphone technologies advance at a rapid pace – chipsets, displays, cameras and so on. All except battery capacity, which increases at a snail’s pace. Honor thinks it has found a solution – the industry’s first silicon-carbon battery. It promises 12.8% higher energy density compared to current lithium batteries that use graphite for one of the electrodes (the anode). To put that in more concrete terms, the Honor Magic5 Pro has a standard 5,100mAh battery. If it used a silicon-carbon battery instead, it would…
