Quantum computing has the potential to revolutionise the processing power at our fingertips, but for the moment a lot of it is just potential.

Researchers have been uncertain on whether we’ll ever be able to harness quantum computing in a practical, affordable, realistic way. But we might have an exciting new lead.

Two new studies show how quantum technologies can work with everyday electronics – specifically, transmitting quantum information using devices made from silicon carbide, a material which is already used everywhere from LED lights to telescopes.

Crisis on Infinite Earths was seeing the destruction of the Multiverse — but there have been hints that it could be reversed in the end.

BOSTON, MA — Xfinity Comcast cable television and Internet customers were without service Wednesday morning, thanks to the company’s sixth major outage in the past five days. A spokesperson for Comcast was not immediately available for comment. In addition to the outage in Massachusetts, there were reports of service interruptions in other parts of the country.

Businesses and residential customers on the North Shore were particularly hard hit by the outage. In Salem, the recreational marijuana retailer Insa said it would be closed until further notice because of the outage. At least 15 North Shore communities are affected by the outage.

A Kansas-based company launched a clinical trial in Colombia to reverse aging. But will it work?

On Dec. 11, 2019, a general framework for incorporating and correcting for nonclassical electromagnetic phenomena in nanoscale systems will be presented in the journal Nature.

More than 150 years have passed since the publication of James Clerk Maxwell’s “A Dynamical Theory of the Electromagnetic Field” (1865). His treatise revolutionized the fundamental understanding of electric fields, magnetic fields and light. The 20 original equations (elegantly reduced to four today), their boundary conditions at interfaces, and the bulk electronic response functions (dielectric permitivity and magnetic permeability) are at the root of the ability to manipulate electromagnetic fields and light.

Life without Maxwell’s equations would lack most current science, communications and technology.

This could usher in higgs exotic physics computing that is beyond even quantum computers.

When a continuous symmetry of a physical system is spontaneously broken, two types of collective modes typically emerge: the amplitude and phase modes of the order-parameter fluctuation. For superconductors, the amplitude mode is recently referred to as the ‘’Higgs mode’’ as it is a condensed-matter analogue of a Higgs boson in particle physics. Higgs mode is a scalar excitation of the order parameter, distinct from charge or spin fluctuations, and thus does not couple to electromagnetic fields linearly. This is why the Higgs mode in superconductors has evaded experimental observations over a half century after the initial theoretical prediction, except for a charge-density-wave coexisting system.

Higgs and Goldstone modes are possible collective modes of an order parameter on spontaneously breaking a continuous symmetry. Whereas the low-energy Goldstone (phase) mode is always stable, additional symmetries are required to prevent the Higgs (amplitude) mode from rapidly decaying into low-energy excitations. In high-energy physics, where the Higgs boson¹ has been found after a decades-long search, the stability is ensured by Lorentz invariance. In the realm of condensed-matter physics, particle–hole symmetry can play this role² and a Higgs mode has been observed in weakly interacting superconductors^3,4,5. However, whether the Higgs mode is also stable for strongly correlated superconductors in which particle–hole symmetry is not precisely fulfilled or whether this mode becomes overdamped has been the subject of numerous discussions^{6,7,8,9,10,11}. Experimental evidence is still lacking, in particular owing to the difficulty of exciting the Higgs mode directly. Here, we observe the Higgs mode in a strongly interacting superfluid Fermi gas. By inducing a periodic modulation of the amplitude of the superconducting order parameter Δ, we observe an excitation resonance at the frequency 2Δ/h. For strong coupling, the peak width broadens and eventually the mode disappears when the Cooper pairs turn into tightly bound dimers signalling the eventual instability of the Higgs mode.

The procedure, donation after circulatory death or DCD, involves taking organs from a donor whose heart has stopped beating after being taken off of life support after a fatal injury or illness when there is no potential for recovery.

Conventional organ donations occur after brain death, which means that while all brain functions have stopped and the person is legally and clinically dead, machines can continue to keep oxygen and blood flowing throughout the body, preserving the healthy organs for donation.

After a circulatory death, however, organs are deprived of oxygen as the circulatory system shuts down, potentially damaging the donor organs and making it difficult to use them for transplant.

A California startup made the first cross-country trip completed by an autonomous truck, delivering 40,000 pounds of butter in under three days. The self-driving truck drove from the west coast to Pennsylvania.
