A new theory suggests gravity could possibly be the result of entropy—which would mean everything in the universe would fall apart if it all remained unchanged.
NVIDIA may have just revolutionized computing forever with the launch of DIGITS, the world’s first personal AI supercomputer. By harnessing the power of GPU-accelerated deep learning—the same technology that drives top-tier high-performance computing (HPC) clusters—DIGITS shrinks massive supercomputing capabilities into a desktop-friendly system.
This compact yet powerful platform enables data scientists, researchers, and developers to rapidly train, test, and refine complex neural networks using NVIDIA’s state-of-the-art GPUs and software ecosystem. Built for deep learning, machine learning, and big data analytics, DIGITS seamlessly integrates tensor cores, parallel processing, and accelerated computing into a single, plug-and-play solution.
Microsoft Microsoft is accelerating its push to compete with OpenAI, its longtime collaborator, according to a report.
Past neuroscience studies suggest that memories of events that occurred at short time intervals from one another are often connected, via a process referred to as memory linking. While memory linking is now a well-documented phenomenon, its neural underpinnings have not been fully elucidated.
Researchers at the University of California Los Angeles (UCLA) recently carried out a study aimed at better understanding the neural processes that contribute to memory linking in the mouse brain. Their findings, published in Nature Neuroscience, suggest that dendritic plasticity, the adaptation of dendrites (i.e., branch-like extensions of neurons) over time, plays a key role in the linking of memories.
“A few years back, in a landmark study published in Nature in 2016, we demonstrated that memories formed a few hours apart are linked because they are stored in a common set of neurons in the hippocampus,” Alcino Silva, senior author of the paper, told Medical Xpress. “We wanted to know: Where within these neurons are these memories stored and linked? What was causing these neurons to be recruited?”
The U.S. military’s classified mini space shuttle returned to Earth on Friday after circling the world for 434 days.
The space plane blasted into orbit from NASA’s Kennedy Space Center in December 2023 on a secret mission. Launched by SpaceX, the X-37B vehicle carried no people, just military experiments.
Its predawn touchdown at Vandenberg Space Force Base in California was not announced until hours after the fact. Photos showed the white-and-black space plane parked on the runway in darkness.
NASA and the Italian Space Agency made history on March 3 when the Lunar GNSS Receiver Experiment (LuGRE) became the first technology demonstration to acquire and track Earth-based navigation signals on the moon’s surface.
The LuGRE payload’s success in lunar orbit and on the surface indicates that signals from the GNSS (Global Navigation Satellite System) can be received and tracked at the moon. These results mean NASA’s Artemis missions, or other exploration missions, could benefit from these signals to accurately and autonomously determine their position, velocity, and time. This represents a steppingstone to advanced navigation systems and services for the moon and Mars.
“On Earth we can use GNSS signals to navigate in everything from smartphones to airplanes,” said Kevin Coggins, deputy associate administrator for NASA’s SCaN (Space Communications and Navigation) Program. “Now, LuGRE shows us that we can successfully acquire and track GNSS signals at the moon. This is a very exciting discovery for lunar navigation, and we hope to leverage this capability for future missions.”
Physicists from the National University of Singapore (NUS) have synthesized very pure superconducting materials and redefined the critical role of hydrogen in the newly discovered nickel-oxide superconductors.
Their findings were published concurrently in the journals Nature Communications and Physical Review Letters.
Superconductivity is an exciting phenomenon where electrical resistance disappears, and it holds transformative potential for revolutionizing energy technologies. Despite its potential, the origin and fundamental mechanism of superconductivity remain one of the greatest mysteries in physics.
A new quantum computing breakthrough has sent shockwaves through the tech world. Researchers at USTC unveiled Zuchongzhi-3, a 105-qubit machine that processes calculations at speeds that dwarf even the most powerful supercomputers. It marks another leap forward in the quest for quantum supremacy, with the team demonstrating computational power orders of magnitude beyond Google’s latest results.
By miniaturizing cold atom trapping with integrated photonics, researchers are making quantum technologies portable. Their photonic chip system replaces traditional free-space optics, offering a path toward highly precise, deployable quantum sensors and computing tools. Bringing Quantum Experime.
