Posted by in categories: sustainability, transportation

The world’s EV leader, BYD (OTC: BYDDY), announced a stock buyback plan as it continues expanding into new markets. BYD is pushing into different segments with new luxury EVs and mid-size electric SUVs.

After selling a record 526,409 all-electric vehicles in the fourth quarter of 2023, BYD topped Tesla to become the best-selling EV maker globally.

The automaker’s success was fueled by its lineup of affordable EVs like the Dolphin, Atto 3 (Yuan Plus in China), and Seal. However, BYD is quickly expanding into new segments.

Plasma scientists develop computer programs that could reduce the cost of microchips, stimulate manufacturing

Posted by in categories: computing, mobile phones, nuclear energy, transportation

Fashioned from the same element found in sand and covered by intricate patterns, microchips power smartphones, augment appliances and aid the operation of cars and airplanes.

Now, scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) are developing computer simulation codes that will outperform current simulation techniques and aid the production of microchips using plasma, the electrically charged state of matter also used in fusion research.

These codes could help increase the efficiency of the manufacturing process and potentially stimulate the renaissance of the chip industry in the United States.

New computer model of lung tissue could herald safer radiotherapy for cancer

Posted by in categories: biotech/medical, computing

An innovative computer model of a human lung is helping scientists simulate, for the first time, how a burst of radiation interacts with the organ on a cell-by-cell level.

This research, carried out at the University of Surrey and GSI Helmholtzzentrum für Schwerionenforschung, Darmstadt, could lead to more targeted treatments for and reduce the damage caused by . The research is published in the journal Communications Medicine.

Dr. Roman Bauer, Senior Lecturer at the University of Surrey, said, “Doctors could one day use our model to choose the right length and strength of radiotherapy—tailored to their patient. This is exciting enough—but others could use our technique to study other organs. This could unlock all kinds of medical knowledge and could be great news for and future patients.”

Chinese Scientists Unveil Secrets of Bright-Dark Exciton Transition in a Semiconductor Material

Posted by in categories: particle physics, quantum physics

A collaborative study conducted by Prof. Zhao Jin, Associate Prof. Zheng Qijing from the University of Science and Technology of China (USTC), and Prof. Hrvoje Petek from the University of Pittsburgh, has revealed the mechanisms behind the transition of bright-dark excitons in anatase TiO2. Their findings have been published in Proceedings of the National Academy of Sciences.

Understanding Excitons

Excitons, quasi-particles formed by the binding of electrons and holes in condensed matter systems via Coulomb interaction, exhibit distinct properties as bright and dark excitons. While bright excitons directly couple with light and play a pivotal role in light absorption, dark excitons, with their relatively longer lifetimes, hold significance in quantum information processing, Bose-Einstein condensation, and light-energy harvesting.

NASA’s Intuitive Machines Moon Mission Ignites With Revolutionary Liquid Methane Engine

Posted by in categories: innovation, space travel

NASA ’s lunar mission with Intuitive Machines showcases successful launch, innovative engine testing, and advanced navigation technology for precise lunar exploration.

After a successful launch on February 15, six NASA science instruments and technology demonstrations continue their journey to the Moon aboard Intuitive Machines’ lander named Odysseus. The company confirmed communications contact with its mission operations control in Houston, and its lander continues to perform as expected.

Known as IM-1, Intuitive Machines successfully transmitted its first images back to Earth on February 16. These were captured shortly after separation from SpaceX ’s second stage, on Intuitive Machines’ first journey to the Moon as part of the agency’s Commercial Lunar Payload Services initiative and Artemis campaign.

A Boost in Dopamine During Adolescence Permanently Amplifies Impulsivity and Aggression

Posted by in categories: biotech/medical, neuroscience

Drugs blocking dopamine transporters may be harmful for healthy teens but helpful for those with pathological dopamine hypofunction.

In a breakthrough finding researchers at Columbia University Irving Medical Center identified a sensitive developmental period during adolescence that impacts adult impulsivity, aggression, and dopamine function in mice.

As organisms grow from embryo to adult, they pass through sensitive time periods where developmental trajectories are influenced by environmental factors. These windows of plasticity often allow organisms to adapt to their surroundings through evolutionarily selected mechanisms.

Challenging Traditional Theories — Physicists Develop New Method To Quantify Quantum Entanglement

Posted by in categories: computing, quantum physics

Entanglement is a phenomenon in quantum physics where two or more systems become interconnected in a manner that makes it impossible to describe their quantum states separately. When systems interact and become entangled, they exhibit strong correlations. This concept is crucial for quantum computing, as the degree of entanglement directly influences the optimization and efficiency of a quantum computer. The more entangled the systems are, the better the performance of the quantum computer.

A study conducted by researchers affiliated with the Department of Physics at São Paulo State University’s Institute of Geosciences and Exact Sciences (IGCE-UNESP) in Rio Claro, Brazil, tested a novel method of quantifying entanglement and the conditions for its maximization. Applications include optimizing the construction of a quantum computer.

An article on the study is published as a Letter in Physical Review B.

Orbital Magic: Japanese Scientists Pave the Way for Next-Gen Spintronics

Posted by in categories: materials, particle physics

Directing magnetization with a low electric field is crucial for advancing effective spintronic devices. In spintronics, the characteristics of an electron’s spin or magnetic moment are leveraged for information storage. By modifying orbital magnetic moments through strain, it’s possible to manipulate electron spins, leading to an enhanced magnetoelectric effect for superior performance.

Japanese researchers, including Jun Okabayashi from the University of Tokyo, revealed a strain-induced orbital control mechanism in interfacial multiferroics. In multiferroic material, the magnetic property can be controlled using an electric field—potentially leading to efficient spintronic devices. The interfacial multiferroics that Okabayashi and his colleagues studied consist of a junction between a ferromagnetic material and a piezoelectric material. The direction of magnetization in the material could be controlled by applying voltage.

NASA’s Next-Gen Exoplanet-Imaging Technology Advances Search for Extraterrestrial Life

Posted by in category: alien life

NASA ’s Roman Space Telescope ’s Coronagraph Instrument, designed to observe distant exoplanets by blocking stellar light, has passed essential tests, marking a significant advancement in space observation technology and the search for extraterrestrial life.

A cutting-edge tool to view planets outside our solar system has passed two key tests ahead of its launch as part of the agency’s Roman Space Telescope by 2027.

The Coronagraph Instrument on NASA’s Nancy Grace Roman Space Telescope will demonstrate new technologies that could vastly increase the number of planets outside our solar system (exoplanets) that scientists can directly observe. Designed and built at the agency’s Jet Propulsion Laboratory in Southern California, it recently passed a series of critical tests ahead of launch. That includes tests to ensure the instrument’s electrical components don’t interfere with those on the rest of the observatory and vice versa.
