Artificial intelligence (AI) not only delivers impressive performance but also demands significant energy. The more complex the tasks it undertakes, the greater the energy consumption. Scientists Víctor López-Pastor and Florian Marquardt from the Max Planck Institute for the Science of Light in Erlangen, Germany, have developed a method for more efficient AI training. Their method utilizes physical processes, diverging from traditional digital artificial neural networks.

Open AI, the company responsible for the development of GPT-3, the technology powering ChatGPT, has not disclosed the amount of energy needed for the training of this advanced and knowledgeable AI Chatbot.

According to the German statistics company Statista, this would require 1,000 megawatt hours – about as much as 200 German households with three or more people consume annually. While this energy expenditure has allowed GPT-3 to learn whether the word ‘deep’ is more likely to be followed by the word ‘sea’ or ‘learning’ in its data sets, by all accounts it has not understood the underlying meaning of such phrases.

The DOE’s shipment of 0.5 kilograms of plutonium-238 to Los Alamos National Laboratory marks a milestone in producing fuel for NASA

Established in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. Its vision is “To discover and expand knowledge for the benefit of humanity.” Its core values are “safety, integrity, teamwork, excellence, and inclusion.” NASA conducts research, develops technology and launches missions to explore and study Earth, the solar system, and the universe beyond. It also works to advance the state of knowledge in a wide range of scientific fields, including Earth and space science, planetary science, astrophysics, and heliophysics, and it collaborates with private companies and international partners to achieve its goals.

Researchers using ALMA

The Atacama Large Millimeter/submillimeter Array (ALMA) is the largest ground-based facility for observations in the millimeter/submillimeter regime in the world. ALMA comprises 66 high-precision dish antennas of measuring either 12 meters across or 7 meters across and spread over distances of up to 16 kilometers. It is an international partnership between Europe, the United States, Japan, and the Republic of Chile.

Researchers have manipulated light to exhibit quantum backflow, a step towards understanding complex quantum mechanics and its practical applications in precision technologies.

Scientists at the University of Warsaw’s Faculty of Physics have superposed two light beams twisted in the clockwise direction to create anti-clockwise twists in the dark regions of the resultant superposition. The results of the research have been published in the prestigious journal Optica. This discovery has implications for the study of light-matter interactions and represents a step towards the observation of a peculiar phenomenon known as a quantum backflow.

“Imagine that you are throwing a tennis ball. The ball starts moving forward with positive momentum. If the ball doesn’t hit an obstacle, you are unlikely to expect it to suddenly change direction and come back to you like a boomerang,” notes Bohnishikha Ghosh, a doctoral student at the University of Warsaw’s Faculty of Physics. “When you spin such a ball clockwise, for example, you similarly expect it to keep spinning in the same direction.”

A groundbreaking study by University of Leeds scientists proposes that Be stars are part of triple star systems, not binary systems as previously thought. This finding, derived from Gaia satellite data, challenges conventional star formation theories and could impact our knowledge of black holes, neutron stars, and gravitational waves.

Gravitational waves are distortions or ripples in the fabric of space and time. They were first detected in 2015 by the Advanced LIGO detectors and are produced by catastrophic events such as colliding black holes, supernovae, or merging neutron stars.

A team of researchers headed by Prof. Wang Qun at the University of Science and Technology of China, under the Chinese Academy of Sciences, has achieved a breakthrough in the theoretical understanding of vector meson spin physics, focusing on the unique properties of ϕ mesons produced during collisions between gold nuclei.

Their findings published in the journal Physical Review Letters

Physical Review Letters (PRL) is a peer-reviewed scientific journal published by the American Physical Society. It is one of the most prestigious and influential journals in physics, with a high impact factor and a reputation for publishing groundbreaking research in all areas of physics, from particle physics to condensed matter physics and beyond. PRL is known for its rigorous standards and short article format, with a maximum length of four pages, making it an important venue for rapid communication of new findings and ideas in the physics community.

Macrophages, small but essential cells in the immune system, hold promise for cell-based therapies in numerous health conditions. Unlocking the full potential of macrophage therapies depends on our ability to observe their activities within the body. Now, researchers from Penn State have potentially developed a method to monitor these cells in action.

In a study published in the journal Small, the Penn State researchers report a novel ultrasound imaging technique to view macrophages continuously in mammal tissue, with potential for human application in the future.

“A macrophage is a type of immune cell that is important in nearly every function of the immune system, from detecting and clearing pathogens to wound healing,” said corresponding author Scott Medina, the William and Wendy Korb Early Career Associate Professor of Biomedical Engineering. “It is a component of the immune system that really bridges the two types of immunity: innate immunity, which responds to things very quickly but in a not very precise way, and adaptive immunity, which is much slower to come online but responds in a much more precise way.”

Max’s Scavengers Reign is making waves in the science-fiction world for brilliantly conceptualizing and constructing an alien ecosystem that feels truly out of this world. Since its October 19 streaming premiere, we’ve been presented with a 12-episode run that places an exceptionally strong emphasis on the series’ setting in a way that makes the environment a more compelling character than the actual characters themselves. Scavengers Reign is a visually stunning and surreal take on humanity’s relationship with nature, and die-hard sci-fi fans can’t get enough of it.

YouTube creator NerdWriter1 posted a short breakdown of the series and grapples with the other-worldliness that Scavengers Reign presents. He likens the series’ emphasis on the environment to Werner Herzog’s documentary Burden of Dreams, in which Herzog suggests that nature is indifferent to humanity. In other words, nature has its own agenda, and the idea of harmony between humanity and nature is something that doesn’t necessarily exist when you consider how punishing an unfamiliar ecosystem can be to humans who are trying to traverse the vast landscapes full of unknown flora, fauna, and critters who rule the land.

Much like the real-life chaos that’s found in Burden of Dreams, Scavengers Reign presents a harrowing world in which its protagonists are tasked with navigating through unfamiliar territory.
