OpenAI is betting big on ChatGPT, which is generating at least $4 billion in annualized revenue. But that’s not the only application the AI firm is hoping will make big bucks. If you saw our story last month detailing OpenAI’s financial projections, you might have noticed an intriguing reference…
The hippocampus is essential for episodic memory, yet its coding mechanism remains debated. In humans, two main theories have been proposed: one suggests that concept neurons represent specific elements of an episode, while another posits a conjunctive code, where index neurons code the entire episode. Here, we integrate new findings of index neurons in humans and other animals with the concept-specific memory framework, proposing that concept neurons evolve from index neurons through overlapping memories. This process is supported by engram literature, which posits that neurons are allocated to a memory trace based on excitability and that reactivation induces excitability. By integrating these insights, we connect two historically disparate fields of neuroscience: engram research and human single neuron episodic memory research.
Navier-Stokes equations are shown to emerge from a generalized hydrodynamics description for nearly integrable 1D models.
Supersolids are strange materials that behave like both a solid and a fluid due to quantum effects – and now researchers have created an intriguing new type of supersolid from laser light.
Hydrogen energy promises a clean and sustainable future, but its production often depends on expensive platinum-based catalysts, making it costly. The industry needs more affordable alternatives to platinum to make hydrogen energy more viable.
Researchers from the Tokyo University of Science (TUS) have developed a new catalyst called bis(diimino)palladium coordination nanosheets (PdDI). These low-cost palladium-based nanosheets match platinum’s performance in producing hydrogen.
France just achieved a nuclear fusion breakthrough, making limitless energy virtually inevitable.
In a major achievement, France’s WEST Tokamak reactor has maintained a plasma reaction for over 22 minutes, setting a new world record in the quest for sustainable fusion energy.
énergie atomique et aux énergies alternatives (CEA), the experiment surpassed China’s previous record of 1,066 seconds, reaching 1,337 seconds of sustained plasma. + This milestone is a major step toward commercial fusion power, which promises unlimited, clean energy by harnessing the same process that powers the Sun. The challenge lies in achieving a self-sustaining reaction while maintaining extreme temperatures of up to 150 million°C (270 million°F) without damaging reactor components.
While WEST itself won’t become a commercial reactor, the data gathered will be instrumental in developing ITER, the world’s largest fusion project, currently under construction in southern France.
CEA scientists plan to extend reaction times further, increasing power levels and plasma stability. If successful, these advancements could bring humanity closer to realizing the long-held dream of clean, virtually limitless energy, potentially transforming global power generation in the future.
