Sodium-Ion Batteries Keep 90% Capacity at -40°C, Cost 30% Less Than LFP
CATL says its sodium-ion batteries retain 90% capacity at -40°C and cost 30% less than LFP, but their 175 Wh/kg density currently limits them to affordable small EVs.
Google Splits TPUv8 into Training and Inference Chips, Promises 3x Faster AI
Google's new TPU 8t and TPU 8i chips claim 3x faster model training and 80% better performance per dollar. The company says it will still offer Nvidia's latest chips and is collaborating on networking tech.
Higher Neutrophil Ratio in Blood Predicts Alzheimer's Years Before Symptoms
A high neutrophil-to-lymphocyte ratio from a routine blood test was linked to increased dementia risk in 370,000 people. The link held for near- and long-term risk, but a direct cause-effect relationship remains unconfirmed.
Curiosity Rover Finds DNA-Like Molecule on Mars in First-Ever Off-World Chemical Test
A nitrogen-bearing molecule similar to DNA-Like Molecule was detected on Mars for the first time using a new chemical experiment. The method cannot distinguish between life and geologic origins.
Vercel Breach: OAuth Hijack Exposed Customer API Keys, Source Code
Attackers gained access through a compromised employee Google account linked to a third-party app, exposing unencrypted credentials. Vercel warns of downstream breaches across "hundreds of users across many organizations."
Soil-Powered Fuel Cell Generates 68 Times More Power Than Sensors Need
A dirt-powered fuel cell using soil microbes generated 68 times more power than required to run its sensors. It lasted 120% longer than similar technologies and worked in both dry and flooded conditions. The researchers are now working to make it fully biodegradable.
Quantum-Informed AI Outperforms Standard Models Using Hundreds of Times Less Memory
A hybrid quantum-AI method achieved 20% greater accuracy in predicting chaotic systems while requiring hundreds of times less memory than conventional approaches. The quantum computer processes data only once, avoiding hardware limitations.
Natural Hormone Reverses Obesity by Burning Energy, Not Curbing Appetite
FGF21 reversed obesity in mice by activating a hindbrain circuit that increases energy burning rather than suppressing hunger. The mechanism differs from GLP-1 drugs like Ozempic. Whether the same circuit reverses fatty liver disease remains untested.
Liver 'Zombie' Cells Hit 80% in Aging Mice; Removing Them Reversed Damage
Senescent macrophages rose from 5% to 60-80% of liver immune cells in older mice. Drug elimination restored liver size and body weight without diet change. Human applicability limited by ABT-263 toxicity.
One in Four U.S. Adults Now Use AI for Health Advice, Survey Finds
Over 66 million Americans report using AI tools for physical or mental healthcare information. 71% cite speed as motivation, yet only 4% strongly trust the accuracy. 14% skipped provider visits based on AI advice.
Amazon to Pay $11.6 Billion for Globalstar, Become iPhone's Primary Satellite Provider
Amazon will acquire Globalstar for $11.57 billion in cash or stock, giving it Apple's satellite business for Emergency SOS and messaging. The merger won't close until 2027, with Amazon's own D2D service not launching until 2028.
Linux 7.0 Promotes Rust to Stable, Concluding 'Experiment'
Rust support graduates from experimental after the 2025 Kernel Maintainers Summit. The shift brings memory-safe code into the stable kernel for the first time. Most distributions will delay packaging until their own validation cycles complete.
