Giant Trees Efficiently Transport Water to Their Highest Branches

·1 views

A study from the University of Exeter has found that giant trees face no significant difficulty in moving water from their roots to their topmost branches. Researchers investigated how tall trees manage hydraulic water transport across extreme heights. The findings challenge previous assumptions that height itself poses a major physiological challenge for large trees. The study contributes to a better understanding of how the world's tallest trees sustain their growth and survival.

Tutorial: Train Skin Cancer AI on Hospital Data Without Accessing Raw Images

A developer guide published on DEV Community explains how to build a privacy-preserving skin cancer classifier using Federated Learning, PySyft, and PyTorch. The approach addresses a core challenge in medical AI: hospitals cannot share patient data due to regulations like HIPAA and GDPR. Federated Learning solves this by sending the model to the data rather than centralizing the data itself, meaning only encrypted model gradients — not raw images — leave each hospital. The tutorial simulates two hospital nodes and incorporates Differential Privacy via Opacus to guard against membership inference attacks. The method is demonstrated using the HAM10000 skin lesion dataset as a reference use case.

Korea, Japan, Qualcomm Lead $610B Global AI Hardware Investment Surge

More than $610 billion in AI hardware capital commitments were announced globally within a single week, led by South Korea's $550 billion pledge to build four new memory fabrication plants. Japan contributed $6 billion to support SoftBank-led AI model development, while Kawasaki Heavy Industries issued a $1 billion bond for AI infrastructure. Qualcomm unveiled a new AI accelerator that bypasses high-bandwidth memory, offering a potential alternative to NVIDIA's dominant CUDA-HBM-NVLink stack. Analysts note that the AI hardware bottleneck has progressively shifted from GPU scarcity to memory and now power constraints. If Qualcomm's approach succeeds, it could significantly reduce inference costs and make AI application development more economically viable.

MSI Center Software Found to Contain Critical SYSTEM Privilege Escalation Flaw

A security vulnerability has been discovered in MSI Center, a utility software developed by hardware manufacturer MSI. The flaw reportedly allows an attacker to gain SYSTEM-level privileges on a Windows machine within seconds. SYSTEM privileges represent the highest level of access on a Windows system, enabling full control over the affected device. The details of the exploit were published by a security researcher at mrbruh.com. Users of MSI Center may be at risk until a patch is issued by MSI.

Solon 4.0 ReActAgent Enables AI Agents to Query Databases and Call APIs

Solon 4.0 introduces ReActAgent, a framework for building AI agents capable of reasoning and taking real-world actions beyond simple text generation. The ReActAgent implements a cognitive loop — Thought, Action, Observation — allowing agents to call external tools, query databases, and fetch live data iteratively. Developers can integrate the framework by adding the solon-ai-agent module and configuring a ChatModel powered by supported large language models such as Qwen3-32B or Llama 3.2. The framework supports both API-based and YAML-based configuration, making it adaptable for various deployment environments. According to the tutorial, ReActAgent has already seen production use in automated customer support, data analysis, and multi-step workflow automation.
