  • The latest version of xAI's Grok can process images

    xAI, the OpenAI competitor founded by Elon Musk, has introduced the first version of Grok that can process visual information. Grok-1.5V is the company's first-generation multimodal AI model, which cannot only process text, but also "documents, diagrams, charts, screenshots and photographs." In xAI's announcement, it gave a few samples of how its capabilities can be used in the real world. You can, for instance, show it a photo of a flow chart and ask Grok to translate it into Python code, get...

  • Using deep learning to image the Earth's planetary boundary layer

    Although the troposphere is often thought of as the closest layer of the atmosphere to the Earth's surface, the planetary boundary layer (PBL)—the lowest layer of the troposphere—is actually the part that most significantly influences weather near the surface. In the 2018 planetary science decadal survey, the PBL was raised as an important scientific issue that has the potential to enhance storm forecasting and improve climate projections.

  • Neuronal gateway to essential molecules in learning and memory discovered on atomic scale

    Learning from an experience, remembering an anecdote or changing an attitude are examples that reveal how all our behavior is the result of the exchange of chemical compounds—neurotransmitters—between neurons. Unraveling what exactly happens at the molecular level when neurons "talk" to each other at synapses is crucial for understanding the human brain in general and, in particular, for helping to solve mental health problems.
