In Tennessee, I was placed into two different state contracted group home over $20 worth of mid grade cannabis and probation violations for home invasions actually done by upper class white junkies with politically connected parents. Once I had all my panels torn out of my car as soon as I crossed into Clinton from Oak Ridge while giving a black man a ride home by a sloppy roided out Clinton “drug task force”. They accused me of drug trafficking and said they knew I had just met my dealer, who I had just texted for a personal amount of pills, manufactured by an Israeli drug company, but never met, a son of another politically connected white man who was politically who also sold crack. They could only have eavesdropped on my text messages with spy tech Israel sold them in violation of the U.S. constitution and federal law. The group homes were ran by abusive fundamentalist cults with state contracts. Everyone I brought up the illegality of this to ignored everything I said. Tennessee is a racist gestapo communist Israeli owned shithole. Oh the irony of Republicans in a Republican state complaining about communism.

Materials scientist describes new world order for glasses, liquids

In 1543, Copernicus pitched the heliocentric idea that the Earth orbited the sun. His theory took 150 years to catch on and more than 400 years for the Vatican to officially accept it. Likewise, distinguished materials scientist Takeshi Egami has spent his career revealing the complex atomic structure of metallic glass and other liquids—sometimes sharing theories with initially resistant minds in the scientific community. However, he is willing to go the distance to bring his colleagues on board to his latest discoveries. The noncrystalline, amorphous atomic structure of liquids and glasses is, quite literally, all over the place. The landscape is chaotic: disorderly atoms are scattered about like tapioca pearls in a freshly shaken boba tea. Egami studies these materials at the Department of Energy's Oak Ridge National Laboratory and the University of Tennessee, Knoxville, or UTK. He directed the UT-ORNL Joint Institute for Neutron Sciences from 2008 to 2015. Egami and his colleagues in ORNL's Materials Science and Technology Division use neutron scattering and synchrotron X-ray to see, with increasing clarity, the structure, dynamics, transition and deformation of noncrystalline materials.

Climate Models Need an Upgrade: Plants Absorb 31% More Carbon Than Previously Thought https://www.goodnewsnetwork.org/climate-models-need-an-upgrade-plants-absorb-31-more-carbon-than-previously-thought/

[mindblowingscience]

Oak Ridge National Laboratory scientists identified a gene "hotspot" in the poplar tree that triggers dramatically increased root growth. The discovery supports the development of better bioenergy crops and other plants that can thrive in difficult conditions while storing more carbon belowground. The team used a vast poplar dataset to identify regulator genes that can trigger hundreds of other gene expressions in the tree. They confirmed the molecular function of one hub gene, PtrXB38, and found that plants with the gene produced prolific and deeper roots. The gene even stimulated the growth of aerial roots on stems and leaves. The work is published in the journal New Phytologist. "With more roots, these plants absorb more nutrients, grow larger, are more tolerant to drought and can draw more carbon underground for longer-term storage," said ORNL's Wellington Muchero. The aerial roots may also make the plant more tolerant to flooding. "This naturally occurring gene has implications for biomass production, food production and climate change mitigation."

The Tennessee Department of Safety and Homeland Security added “and Homeland Security” to their name after 9/11. They are the only state that has that added to the name of a state agency. When agents knock on your door, they state they are with DHS. The Department of Homeland Security is a federal agency. They claim it’s to protect classified national security projects going on at Y-12 and ORNL, yet nothing of significance has ever been produced by Y-12 or ORNL for U.S. national security, and there are laboratories in other states that are far ahead of them in the same research they claim to being doing. Y-12 and ORNL are actually private entities owned through subsidiaries and shell corps by the Israeli military.

Record-breaking run on Frontier sets new bar for simulating the universe in exascale era

The universe just got a whole lot bigger—or at least in the world of computer simulations, that is. In early November, researchers at the Department of Energy's Argonne National Laboratory used the fastest supercomputer on the planet to run the largest astrophysical simulation of the universe ever conducted.

The achievement was made using the Frontier supercomputer at Oak Ridge National Laboratory. The calculations set a new benchmark for cosmological hydrodynamics simulations and provide a new foundation for simulating the physics of atomic matter and dark matter simultaneously. The simulation size corresponds to surveys undertaken by large telescope observatories, a feat that until now has not been possible at this scale.

"There are two components in the universe: dark matter—which as far as we know, only interacts gravitationally—and conventional matter, or atomic matter," said project lead Salman Habib, division director for Computational Sciences at Argonne.

"So, if we want to know what the universe is up to, we need to simulate both of these things: gravity as well as all the other physics including hot gas, and the formation of stars, black holes and galaxies," he said. "The astrophysical 'kitchen sink' so to speak. These simulations are what we call cosmological hydrodynamics simulations."

Not surprisingly, the cosmological hydrodynamics simulations are significantly more computationally expensive and much more difficult to carry out compared to simulations of an expanding universe that only involve the effects of gravity.

"For example, if we were to simulate a large chunk of the universe surveyed by one of the big telescopes such as the Rubin Observatory in Chile, you're talking about looking at huge chunks of time—billions of years of expansion," Habib said. "Until recently, we couldn't even imagine doing such a large simulation like that except in the gravity-only approximation."

The supercomputer code used in the simulation is called HACC, short for Hardware/Hybrid Accelerated Cosmology Code. It was developed around 15 years ago for petascale machines. In 2012 and 2013, HACC was a finalist for the Association for Computing Machinery's Gordon Bell Prize in computing.

Later, HACC was significantly upgraded as part of ExaSky, a special project led by Habib within the Exascale Computing Project, or ECP. The project brought together thousands of experts to develop advanced scientific applications and software tools for the upcoming wave of exascale-class supercomputers capable of performing more than a quintillion, or a billion-billion, calculations per second.

As part of ExaSky, the HACC research team spent the last seven years adding new capabilities to the code and re-optimizing it to run on exascale machines powered by GPU accelerators. A requirement of the ECP was for codes to run approximately 50 times faster than they could before on Titan, the fastest supercomputer at the time of the ECP's launch. Running on the exascale-class Frontier supercomputer, HACC was nearly 300 times faster than the reference run.

The novel simulations achieved its record-breaking performance by using approximately 9,000 of Frontier's compute nodes, powered by AMD Instinct MI250X GPUs. Frontier is located at ORNL's Oak Ridge Leadership Computing Facility, or OLCF.

Scientists have made significant advancements in solid-state cooling technology

- By Nuadox Crew -

Researchers have significantly advanced understanding of atomic-scale heat motion in materials, crucial for developing solid-state cooling technology.

This environmentally friendly technology operates without traditional refrigerants or moving parts and uses materials like nickel-cobalt-manganese-indium magnetic shape-memory alloys to exploit the magnetocaloric effect for efficient cooling.

A team led by the Department of Energy’s Oak Ridge National Laboratory recently bridged a crucial knowledge gap in atomic-scale heat motion, promising enhancements for solid-state cooling. Using neutron-scattering instruments, they examined a material considered optimal for this technology.

The material undergoes a phase transition when subjected to a magnetic field, absorbing and releasing heat through the magnetocaloric effect. This behavior is enhanced near disordered states known as ferroic glassy states, which improve the material’s heat storage and release capabilities.

Researchers discovered that localized hybrid magnon-phonon modes in the material significantly impact its thermal properties. Neutron scattering revealed that these modes triple the cooling capacity by storing heat in small, disordered regions.

Researchers turn coal into graphite for clean energy, electric vehicle batteries

Yesterday's polluting fuel could be transformed into a valuable material for tomorrow's electric vehicle batteries, thanks to a wide-ranging research project that utilizes expertise spanning the Department of Energy's Oak Ridge National Laboratory. ORNL researchers created and tested two methods for transforming coal into the scarce mineral graphite, which is used in batteries for electric vehicles and renewable energy storage. The U.S. Geological Survey has classified graphite as a critical material for energy because the domestic supply of natural graphite is so small, and foreign imports are limited. Coal, on the other hand, is both abundant and affordable.
