How mRNA vaccines work Messenger RNA (mRNA) is a short-lived molecule that carries instructions for making a protein. An mRNA vaccine uses this normal cellular process to show the immune system a harmless marker from a pathogen—without exposing the person to the pathogen itself. Mechanism, step by step The vaccine delivers instructions. A laboratory-made strand of mRNA is enclosed in tiny lipid (fat) particles. These particles protect the fragile mRNA and help it enter cells near the injection site. Cells read the mRNA.…

Renewable energy is likely to become the main source of electricity in many parts of the world over the next few decades. Solar panels and wind turbines are already becoming cheaper, more efficient, and easier to install. However, the transition is not simply a matter of building more of them. It also depends on energy storage, stronger power networks, flexible demand, and other sources that can provide electricity when needed.…

Policy Brief: Renewable Energy’s Next Bottleneck Is the Grid Decision Make grid expansion, interconnection reform, storage, and faster permitting the central renewable-energy priority.

Uncertainty in weather, demand, storage, and grid conditions drives renewable-energy curtailment, fossil-fuel peaker use, and disproportionate pollution exposure in communities near conventional power plants. Existing forecasting and optimization tools operate in isolation, rely on centralized data collection, and fail to convert predictions into reliable real-time decisions. This two-year project will develop the first integrated, health-aware artificial-intelligence framework that combines probabilistic forecasting, privacy-preserving federated learning, and grid optimization to coordinate…

The claim “90% of communication is body language” is not supported as a general scientific finding. Likely origin: It is usually a distorted version of psychologist Albert Mehrabian’s late-1960s experiments on communicating feelings and attitudes. Participants judged messages in which a speaker’s words, tone, and facial expression were inconsistent—for example, a positive word delivered with a negative tone. Mehrabian summarized the relative influence on perceived liking as roughly 7% verbal, 38% vocal, and 55% facial. Combining vocal and facial cues produced the famous “93%…

Istanbul Destination Guide Istanbul rewards travelers who slow down, ride the ferries, and explore beyond Sultanahmet. Allow at least 3–5 days; longer if you want neighborhood time or an island escape. (Trip.com) Best time to visit Best: April–May and September–October. These shoulder seasons generally bring comfortable walking weather and fewer crowds than summer. Spring is especially appealing when Emirgan Park’s tulips are in bloom. Also good: June and early November, though conditions are less predictable.…

Renewable-energy systems increasingly rely on AI-based forecasting to balance variable generation, storage, and demand. Yet evidence remains limited on whether more complex models consistently improve operational decisions under real-world distribution shifts. We conducted an empirical study across 240 renewable-energy sites, comprising 120 solar and 120 wind installations, using three years of hourly generation and weather data. We compared gradient-boosted trees and transformer-based forecasting models against a seasonal persistence baseline. Models were evaluated on held-out periods…

In Proceedings of the 48th ACM/EDAC/IEEE Design Automation Conference (DAC) (pp. 620–625). IEEE. This paper frames data centers as flexible electrical loads capable of responding to grid conditions, which supports grids with variable wind and solar generation. It proposes workload and power-management strategies that shift or reduce demand in response to utility signals. Simplified assumptions limit its treatment of rebound effects, market barriers, and…

Imagine Earth has a toy box of energy. Coal and oil are like batteries we can use only once—and they make the room smoky. Sunshine, wind, and moving water are like toys that recharge themselves every day. In the future, more houses will have shiny solar “pancakes” on their roofs. Giant windmill pinwheels will spin, and big batteries will save extra energy like putting cookies in a jar for later. Cars and buses will use electricity instead of smoky fuel. The goal is a cleaner, safer playground for everyone. Now that you’re ten…

Emerging-Markets Inflation Outlook: A 2026 Bump, Not Yet a New Regime Current numbers Inflation across emerging markets is reaccelerating, although estimates differ by country coverage. The OECD’s September 2026 Economic Outlook projects headline inflation in G20 emerging-market economies to rise from 4.1% in 2025 to 4.8% in 2026, before easing to 4.3% in 2027. The UN Department of Economic and Social Affairs presents a more severe picture for the broader developing-economy universe: inflation is forecast to climb from 4.2% to 5.2% in 2026, reflecting higher…
