The new map includes around 1.3 million quasars from across the visible universe and could help scientists better understand the properties of dark matter.

Astronomers have charted the largest-ever volume of the universe with a new map of active supermassive black holes living at the centers of galaxies. Called quasars, the gas-gobbling black holes are, ironically, some of the universe’s brightest objects.

Wafer-scale realization of a nanoscale magnetic tunnel junction hosting a single, ambient skyrmion enables its large readout, efficient switching, and compatibility with lateral manipulation, and thereby provides the backbone for all-electrical skyrmionic device architectures.

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.

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.

Physicists just can’t leave an incomplete theory alone; they try and repair it. When nature is kind, it can lead to a major breakthrough.

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?

New breakthrough research shows that a simple blood test can flag symptoms of Alzheimer’s Disease up to 15 years in advance.

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 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.
