A new quantum approach to solve electronic structures of complex materials

Posted by in categories: chemistry, computing, engineering, information science, quantum physics

If you know the atoms that compose a particular molecule or solid material, the interactions between those atoms can be determined computationally, by solving quantum mechanical equations—at least, if the molecule is small and simple. However, solving these equations, critical for fields from materials engineering to drug design, requires a prohibitively long computational time for complex molecules and materials.

Now, researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory and the University of Chicago’s Pritzker School of Molecular Engineering (PME) and Department of Chemistry have explored the possibility of solving these electronic structures using a quantum .

The research, which uses a combination of new computational approaches, was published online in the Journal of Chemical Theory and Computation. It was supported by Q-NEXT, a DOE National Quantum Information Science Research Center led by Argonne, and by the Midwest Integrated Center for Computational Materials (MICCoM).

New Therapy Found to Prevent Aggressive Brain Cancer Recurrence in Mice

Posted by in categories: biotech/medical, nanotechnology, robotics/AI

A new gel-based treatment for glioblastoma—a highly aggressive form of brain cancer—has shown to be 100% effective at preventing recurrence in mice. Researchers hope the therapy will translate well into human physiology, where it could help resolve tens of thousands of cancer diagnoses every year.

Glioblastoma manifests as a tumor growing on the brain or spinal cord. While many glioblastoma patients have the tumor surgically removed, the mass often returns, even in cases involving post-surgical radiation or chemotherapy. The disease is so persistent that the average patient lives only 12 to 16 months after diagnosis, making glioblastoma one of the most lethal forms of cancer currently understood.

2,600-year-old stone busts of ‘lost’ ancient Tartessos people discovered in sealed pit in Spain

Posted by in category: futurism

Archaeologists in Spain have unearthed five life-size busts of human figures that could be the first-known human depictions of the Tartessos, a people who formed an ancient civilization that disappeared more than 2,500 years ago.

The carved stone faces, which archaeologists date to the fifth century B.C., were found hidden inside a sealed pit in an adobe temple at Casas del Turuñuelo, an ancient Tartessian site in southern Spain. The pieces were scattered amongst animal bones, mostly from horses, that likely came from a mass sacrifice, according to a translated statement (opens in new tab) published April 18.

A quantum leap in computational performance of quantum processors

Posted by in categories: computing, quantum physics

A project led by a group of researchers from Israel’s Bar-Ilan University, in collaboration with TII—the Quantum Research Center in Abu Dhabi, United Arab Emirates, is advancing quantum computing by improving the performance of superconducting qubits, the basic computation units of a superconducting quantum processor. The improved qubit, called a tunable superconducting flux qubit, is a micron-sized superconducting loop where electrical current can flow clockwise or counterclockwise, or in a quantum superposition of both directions.

These quantum features would allow the computer to be much faster and more powerful than a normal computer. For the speed potential to be realized, the quantum computer needs to operate several hundred of qubits simultaneously without having them unintentionally interfering with each other.

As an alternative technology to that existing today in quantum processors, superconducting qubits provide several important advantages: First, they are very fast and reliable; and second, it may be simpler to integrate many flux qubits into a processor compared to current available technology.

High rate of concurrent retinal non perfusion encountered in Pediatric patients with optic nerve hypoplasia

Posted by in category: biotech/medical

A new study published in the American Journal of Ophthalmology suggests that there seems to be a significant rate of concomitant retinal nonperfusion in pediatric optic nerve hypoplasia (ONH) patients.

This study was carried out by Natasha da Cruz and colleagues to report the correlation between peripheral retinal nonperfusion, secondary problems, and optic nerve hypoplasia in pediatric patients.

The Bascom Palmer Eye Institute conducted the Retrospective case series investigation between January 2015 and January 2022. Age under 18 years old, a clinical diagnosis of optic disc hypoplasia, and an acceptable-quality FA were the inclusion criteria.

We Finally Know How Quasars Become The Brightest Objects in The Universe

Posted by in categories: cosmology, materials

The Universe is swarming with galaxies, billions upon billions as far as the eye can see. And among this multitude, some galaxies really stand out in a spectacular way.

These are the quasar galaxies. Powered by an active supermassive black hole guzzling material at such a tremendous rate, they blaze with some of the brightest light in the Universe, lighting up the galactic center right across the electromagnetic spectrum. For decades, astronomers have wondered why some galaxies have such extreme activity and others do not.

Now they think they’ve cracked it. By making a careful study of nearby quasar and non-quasar galaxies, a team led by astrophysicist Jonny Pierce of the University of Hertfordshire in the UK concludes that, in a majority of cases, quasar activity is triggered when two galaxies start the process of colliding and merging.

Is our Universe standing still? Examining Einstein’s key theory through the cosmic “yin-yang”

Posted by in category: futurism

Is there such a thing as absolute motion? Modern science, as represented by Einstein’s theory of relativity, says no. After all, absolute motion would require that there exists a single coordinate system — or common reference point — that all observers could agree is stationary. Such a coordinate system doesn’t exist.

But modern science has also found a way to observe the coordinate system of the entire visible Universe. If one can find a coordinate system in which the visible Universe is stationary, isn’t that the “right” one? What’s the truth behind this, and does it invalidate Einstein’s theory? And how does the yin-yang symbol come into play?

Einstein’s theory of relativity makes many counterintuitive claims, but those claims are consequences of one fundamental assumption: that any individual is perfectly justified in assuming that they are the one, unmoving, thing in the entire Universe. This assertion could be called the “cosmic egotist principle.” Essentially, you are the one thing around which the entire Universe revolves.
