China Room Temperature Superconductor Researcher Had Experiments to Refute Critics

Posted by in categories: chemistry, materials

Chinese researchers are making variations of LK99 room temperature superconductor materials with more sulfur and copper in the chemistry. They are publishing results with stronger magnetic indications of a Meissner effect.

The chinese researchers have been online discussing their room temperature superconducting research and the challenges of the materials.

Here are the issues discussed.

Rotating curved spacetime signatures from a giant quantum vortex

Posted by in categories: cosmology, quantum physics

By stabilizing a stationary giant quantum vortex in superfluid 4He and introducing a minimally invasive way to characterize the vortex flow, intricate wave–vortex interactions are shown to simulate black hole ringdown physics.

Can epigenetic reprogramming reverse aging?

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

The field of aging research has made significant progress over the last three decades, reaching a stage where we now understand the underlying mechanisms of the aging process. Moreover, the knowledge has broadened to include techniques that quantify aging, decelerate its process, as well as sometimes reverse aging.

To date, twelve hallmarks of aging have been identified; these include reduced mitochondrial function, loss of stem cells, increased cellular senescence, telomere shortening, and impaired protein and energy homeostasis. Biomarkers of aging help to understand age-related changes, track the physiological aging process and predict age-related diseases [1].

Longevity. Technology: Biological information is stored in two main ways, the genomes consisting of nucleic acids, and the epigenome, consisting of chemical modifications to the DNA as well as histone proteins. However, biological information can be lost over time as well as disrupted due to cell damage. How can this loss be overcome? In the 1940s, American mathematician and communications engineer Claude Shannon came up with a neat solution to prevent the loss of information in communications, introducing an ‘observer’ that would help to ensure that the original information survives and is transmitted [2]. Can these ideas be applied to aging?

CERN measures coupled resonance structure that may cause particle loss in accelerators for the first time

Posted by in categories: media & arts, particle physics

Whether in listening to music or pushing a swing in the playground, we are all familiar with resonances and how they amplify an effect—a sound or a movement, for example. However, in high-intensity circular particle accelerators, resonances can be an inconvenience, causing particles to fly off their course and resulting in beam loss. Predicting how resonances and non-linear phenomena affect particle beams requires some very complex dynamics to be disentangled.

Rivian gains access to Tesla’s Supercharger network, free adapter coming

Posted by in category: climatology

Rivian has officially gained access to Tesla’s Supercharger network and announced that it will start shipping an adapter to its owners for free next month.

When Tesla opened up its connector to other automakers in the hope of making it the new charging standard in North America, Rivian was one of the first to jump on board after Ford got the ball rolling.

Ford was the first to gain access to the Supercharger network with a new adapter that it started to offer for free to Mustand Mach-E and F-150 Lightning owners last month.

Shell to unload 1,000 retail locations in pivot to EV charging

Posted by in categories: energy, sustainability, transportation

As part of its energy transition strategy, energy giant Shell plans to shed some of its retail locations, including gasoline stations, to focus more on EV charging sites.

“We are upgrading our retail network, with expanded electric vehicle charging and convenience offers, in response to changing customer needs,” Shell said in its 2024 Energy Transition Strategy report. The company plans to “divest around 500 Shell-owned sites (including joint ventures) a year in 2024 and 2025.” The company’s plans were first reported by Bloomberg News.

The closures will shrink the company’s retail footprint by 2.1%. In 2023, the company operated 47,000 locations.

Diamond Can Be Squeezed Into Something Even Harder. Now We Know How to Do It

Posted by in categories: particle physics, quantum physics, supercomputing

Simulations of an elusive carbon molecule that leaves diamonds in the dust for hardness may pave the way to creating it in a lab.

Known as the eight-atom body-centered cubic (BC8) phase, the configuration is expected to be up to 30 percent more resistant to compression than diamond – the hardest known stable material on Earth.

Physicists from the US and Sweden ran quantum-accurate molecular-dynamics simulations on a supercomputer to see how diamond behaved under high pressure when temperatures rose to levels that ought to make it unstable, revealing new clues on the conditions that could push the carbon atoms in diamond into the unusual structure.
