Latest Webb image shows what our Sun looked like as a baby protostar

Posted by in categories: nuclear energy, space

Webb’s NIRCam instrument recently captured this detailed image of the cloudy region around a very young protostar called L1527. Only about 100,000 years old, L1527 isn’t a star yet: it hasn’t fully pulled itself into a proper, stable sphere, and it hasn’t piled on enough mass to kickstart nuclear fusion and start pumping out its own energy. It’s more like “a small, hot, and puffy clump of gas, somewhere between 20 percent and 40 percent the mass of our Sun,” according to the European Space Agency.

But as the latest Webb photos reveal, the young protostar is making an ambitious start.

Could micro nuclear reactors be the future of nuclear energy?

Posted by in categories: nuclear energy, sustainability

Things can always get smaller.

That might also be true for one of our much-debated energy sources. Even though experts claim that nuclear energy is a reliable and sustainable energy source, the nuclear energy debate continues, with small-scale nuclear reactors being developed around the world. They are said to be a safer and less expensive form of nuclear power. On the other hand, full-scale nuclear reactors are large, expensive, and take a long time to build, and making them smaller, portable, cheaper, and safer could ensure that solar, wind, and hydro are not getting all the attention.

US observed Russian navy preparing for possible test of nuclear-powered torpedo

Posted by in categories: military, nuclear energy, robotics/AI

The US observed Russian naval vessels preparing for a possible test of a new nuclear-powered torpedo in recent weeks, a senior US official with direct knowledge told CNN.

Among the vessels which took part in the preparations was the Belgorod, a cruise missile submarine modified for special operations that is able to launch unmanned underwater vehicles including the Poseidon torpedo.

In the last week, the vessels were observed leaving the testing area in the Arctic Sea and heading back to port without carrying out a test. The US believes the Russians may have encountered technical difficulties.

Magnetic Field Heats Up Fusion

Posted by in categories: futurism, nuclear energy

A magnetic field can significantly boost the performance of a large-scale fusion experiment that may lead to a future source of clean power.

Nuclear fusion could provide a clean power source, but one of the technological challenges is maintaining the fuel at a high enough temperature for a long enough time. In a technique called inertial confinement fusion (ICF)—where lasers initiate the nuclear reaction—a magnetic field has been shown to improve heating. Now researchers have shown that a magnetic field can also help in a large-scale experiment with a more complicated design that produces far more energy [1]. The applied field increased the fuel’s temperature by 40% and tripled the fusion reaction’s efficiency. The work provides a step toward increasing the robustness and energy output of the fusion reaction and provides the first proof of concept of magnetization-assisted fusion in a large-scale experiment.

In the simplest version of ICF, synchronized laser pulses hit a capsule filled with cold hydrogen fuel, causing it to implode. The implosion heats the fuel and creates a spot of burning plasma (see Viewpoint: Fusion Turns Up the Heat). The “hot spot” serves as a spark that initiates burning throughout the fuel, driving a self-sustaining fusion reaction that releases energy. However, these implosions can fail to generate significant fusion energy if the fuel pellet has small imperfections on its surface or if the lasers are not perfectly timed. But if the fuel could be heated to temperatures higher than was possible in recent experiments, there would be more margin for error, which could alleviate the sensitivity to such details.

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.”
