A Trio of Firms Want to Clean up Steelmaking
A trio of companies are tackling steel’s carbon footprint by replacing traditional coke‑based reduction with electricity‑driven or greener chemical processes. Two firms have built pilot‑scale electro‑reduction plants that melt iron ore directly using renewable power, while a third adapts conventional blast‑furnace chemistry to run on low‑carbon feedstocks. Together they aim to cut the sector’s emissions, which account for roughly 8% of global greenhouse gases, and prove that large‑scale, low‑carbon steel can be produced commercially.
Should You Track Your VO2 Max?
The Economist highlights a surge in interest around VO₂ max after Norwegian triathlete Kristian Blummenfelt posted a record‑breaking score of roughly 84 ml kg⁻¹ min⁻¹. Traditionally a metric for elite athletes, VO₂ max is now being promoted by fitness influencers as a personal health dashboard. Wearable...
Is Playing Music Good for the Brain?
Recent research confirms that actively playing music reshapes the brain, enhancing neuroplasticity, memory, and executive function. Studies using MRI and EEG show increased gray‑matter volume in auditory, motor, and prefrontal regions among both professional musicians and hobbyists. The cognitive benefits...
Rapid-Charging EV Batteries Are on the Way
Rapid‑charging technology is moving from prototype to commercial deployment, promising to refill electric‑vehicle batteries in minutes rather than hours. Automakers and battery firms are unveiling ultra‑fast chargers that can add 300‑plus miles in under five minutes, leveraging high‑voltage (800V) platforms...
Should You Take GLP-1 Drugs for Longevity?
GLP‑1 receptor agonists, originally approved for type 2 diabetes and obesity, are now attracting interest as potential longevity agents. Early animal studies suggest these drugs can extend lifespan by improving metabolic health and mimicking caloric restriction. Human evidence remains anecdotal, with...
Data Centres in Space: Less Crazy than You Think
Tech giants are exploring space‑based data centres to power AI workloads. Elon Musk predicts feasibility within two to three years, while OpenAI’s Sam Altman dismisses the idea as premature. Google plans a test launch next year, and former Google CEO...
AI Tools Are Being Prepared for the Physical World
Google unveiled Project Genie, an experimental AI model that converts text or image prompts into fully interactive, three‑dimensional simulations. The system can render realistic environments or reinterpret artistic styles, letting users explore a park rendered in pointillist technique or a...
