Low-risk ultrasound procedure revolutionizes prostate cancer treatment

Posted by in category: biotech/medical

A new treatment shows promise for revolutionizing prostate cancer treatment, offering a minimally-invasive and relatively low-risk alternative to traditional surgeries and radiotherapies. Called TULSA, this method uses sound waves to eliminate the diseased tissue in the prostate, leaving the rest of the healthy tissues behind. According to the researchers, patients treated with this method experience ‘minimal side effects.’

Immunotherapy study shows how to stop cancer hiding from immune cells

Posted by in category: biotech/medical

The immune system is already our best defense against cancer, but sometimes it needs help. After all, cancer has a knack for deceiving it and hiding from immune cells, giving itself time to grow and spread. Now, researchers at QIMR Berghofer Medical Research Institute in Australia have identified one way it does so, and found a method to counter it in mouse tests.

T and NK cells act like the foot soldiers of the immune system, searching the body for invading pathogens and attacking them. But their activity can be regulated by other immune cells, such as mucosal-associated invariant T cells (MAIT cells), telling them when to attack and when to stand down.

During the new study, the QIMR researchers discovered that if MAIT cells were switched on, they would prevent T and NK cells from attacking tumors. The tumors seem to have figured this out too – the team found that cancer cells actively turn on MAIT cells by displaying molecules called MR1 on their surfaces.

Researchers develop vaccine that targets Crohn’s disease and obesity

Posted by in categories: biotech/medical, health

Researchers with INSERM in Paris have detailed their development of a new vaccine strategy that shows promise for treating inflammatory bowel diseases like Crohn’s disease, as well as metabolic conditions like obesity. Key to the vaccine’s potential effectiveness is gut microbiota, abnormalities of which have been linked to a variety of health conditions. The new vaccine works by modifying these bacteria to protect the intestinal wall.

Scientists Just Created Quantum States in Everyday Electronics

Posted by in categories: computing, quantum physics

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.

Major Xfinity Comcast Outage Affecting Massachusetts

Posted by in categories: business, internet

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.

Cheers! Maxwell’s electromagnetism extended to smaller scales

Posted by in categories: information science, nanotechnology

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.

Higgs Mode in Superconductors

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

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 mode in a strongly interacting fermionic superfluid

Posted by in categories: materials, particle physics

Circa 2018

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 superconductors3,4,5. 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 discussions6,7,8,9,10,11. 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.
