A ten-year journey through the quark–gluon plasma and beyond

Posted by in categories: cosmology, evolution, nuclear energy, particle physics, quantum physics

Quantum chromodynamics (QCD) is one of the pillars of the Standard Model of particle physics. It describes the strong interaction – one of the four fundamental forces of nature. This force holds quarks and gluons – collectively known as partons – together in hadrons such as the proton, and protons and neutrons together in atomic nuclei. Two hallmarks of QCD are chiral symmetry breaking and asymptotic freedom. Chiral symmetry breaking explains how quarks generate the masses of hadrons and therefore the vast majority of visible mass in the universe. Asymptotic freedom states that the strong force between quarks and gluons decreases with increasing energy. The discovery of these two QCD effects garnered two Nobel prizes in physics, in 2008 and 2004, respectively.

High-energy collisions of lead nuclei at the Large Hadron Collider (LHC) explore QCD under the most extreme conditions on Earth. These heavy-ion collisions recreate the quark–gluon plasma (QGP): the hottest and densest fluid ever studied in the laboratory. In contrast to normal nuclear matter, the QGP is a state where quarks and gluons are not confined inside hadrons. It is speculated that the universe was in a QGP state around one millionth of a second after the Big Bang.

The ALICE experiment was designed to study the QGP at LHC energies. It was operated during LHC Runs 1 and 2, and has carried out a broad range of measurements to characterise the QGP and to study several other aspects of the strong interaction. In a recent review, highlights of which are described below, the ALICE collaboration takes stock of its first decade of QCD studies at the LHC. The results from these studies include a suite of observables that reveal a complex evolution of the near-perfect QGP liquid that emerges in high-temperature QCD. ALICE measurements also demonstrate that charm quarks equilibrate extremely quickly within this liquid, and are able to regenerate QGP-melted “charmonium” particle states. ALICE has extensively mapped the QGP opaqueness with high-energy probes, and has directly observed the QCD dead-cone effect in proton–proton collisions. Surprising QGP-like signatures have also been observed in rare proton–proton and proton–lead collisions.

Genetic Information Of World’s Most Radiation-Resistant Organism Decoded

Posted by in categories: bioengineering, biotech/medical, genetics, nuclear energy

Circa 1999 this can lead to genetic editing that allows people to handle even a nuclear fallout level of radiation and even allow them to handle outer space better.


Rockville, MD — No, it’s not the cockroach, but rather a strain of pink bacteria that can survive 1.5 million rads of gamma irradiation — a dose 3,000 times the amount that would kill a human. This dose of radiation shreds the bacteria’s genome into hundreds of pieces. The organism’s remarkable ability to repair this DNA damage completely in a day and go on living offers researchers tantalizing clues to better understanding the mechanism of cellular repair. Advances in this area could in turn improve our understanding of cancer which is frequently caused by unrepaired DNA damage. Genetically engineering the microbe could lead to improved ways to cleanup pollution and to new industrial processes.

U.S. Department of Energy-funded researchers at The Institute for Genomic Research (TIGR) describe the complete genetic sequence of the bacteria Deinococcus radiodurans in the November 19 issue of Science.

“This is a significant accomplishment,” Secretary of Energy Bill Richardson said. “The Department of Energy began microbial genome work to support bold science and to help meet our unique environment and energy mission needs. Besides the insights into the way cells work, this new research may help provide a new safe and inexpensive tool for some of the nation’s most difficult cleanup challenges.”

Machine learning facilitates “turbulence tracking” in fusion reactors

Posted by in categories: nuclear energy, robotics/AI

He and his co-authors took four well-established computer vision models, which are commonly used for applications like autonomous driving, and trained them to tackle this problem.

Simulating blobs

To train these models, they created a vast dataset of synthetic video clips that captured the blobs’ random and unpredictable nature.

What Do We Lack To Be A Type 1 Civilization On The Kardashev Scale?

Watch The Kardashev Scale Type 1: What Would Be Our CIvilization?
https://youtu.be/zHFN8VrLBdc.

A type 1 civilization on the Kardashev scale manages to take advantage of 100% of the energy produced by its planet, control the climate, move continents and even change its planet’s rotation. In this sense, how long does the human race lack to become a type 1 civilization? Are we close to achieving it, or are we still far away?
Ready, let’s start! “Introduction“
The level of technological development of any civilization can be measured mainly by the amount of energy they need. But, it also encompasses the management of that energy and how they use it to develop and grow on their home planet.
Following Kardashev’s definition, a Type I civilization is capable of storing and using all the energy available on its planet; this includes all known electricity generation methods, as well as those that depend on the elements available on the planet, nuclear fusion and fission, geothermal energy, as well as that which they can collect from their star without leaving the planet.
The human race has not yet reached this level of development, but will we ever reach it? And if so, when will we achieve it?
Previously we already made a series of 3 videos in which we address the three types of civilizations that exist according to the Kardashev scale. “Enter here images of the series on the scale of Kardashev.“
But today, we will focus on analyzing why the human race has not yet managed to become a type 1 civilization and how far we need to become one.

Lockheed Martin’s fusion-powered fighter and bomber plans

Posted by in categories: military, nuclear energy

A fascinating new look at the patents and defense projects in the US Military and its hopefully fusion powered future. (FUSION POWER: Only 20 years away for the last 40 years!! 😉)


Back in 2018, Lockheed Martin filed a patent for something it called a “plasma confinement system” — a device small enough to fit inside the fuselage of an F-16 Fighting Falcon that is capable of managing internal temperatures 10 times hotter than the center of the sun.

Dow goes nuclear: chemical firm will install reactors at US chemicals complex

Posted by in categories: chemistry, nuclear energy

DOW will install advanced nuclear reactors at one of its Gulf Coast sites to provide low carbon power and process heat for its chemicals production.

Dow signed a letter of intent with reactor developer X-energy, and plans to buy a minority stake in the company. The plan is to deploy X-energy’s Xe-100 high-temperature gas-cooled reactor technology at one of Dow’s Gulf Coast complexes, with operations expected to begin by 2030.

“Advanced small modular nuclear technology is going to be a critical tool for Dow’s path to zero-carbon emissions,” said Dow CEO Jim Fitterling. “This is a great opportunity for Dow to lead our industry in carbon neutral manufacturing by deploying next-generation nuclear energy.”

France’s Nuclear Reactors Malfunction as Energy Crisis Bites

Posted by in categories: nuclear energy, security

PARIS—France is falling behind in its plans to return the country’s fleet of nuclear reactors to full power this winter after a rash of outages, raising fears that one of Europe’s key sources of electricity won’t be ramped up to counter Russia’s squeeze on the continent’s energy supplies.

The nuclear fleet was designed to act as the front line of France’s energy security. Since Moscow cut the flow of natural gas to Europe—plunging the continent into its biggest energy crisis since the 1970s oil shock—France’s vaunted nuclear fleet has been about as effective as the Maginot Line, the French fortifications that did little to stop the German invasion during World War II.
