L'energia rinnovabile aiuta a alimentare gli Stati Uniti. Durante un'estate da record

-
# Renewable Energy Helps Power the U.S. Through a Record-Breaking Summer The summer of 2026 put the U.S. electricity system under growing pressure. Extreme heat increased air-conditioning demand, while the rapid expansion of data centers added another major source of electricity consumption. But one part of the energy system performed better than many expected: **renewable energy**. Solar and wind generation helped meet rising demand during the summer, while battery storage increasingly allowed solar power to remain useful after sunset. Reuters reported that renewable energy played an important role in reducing the need for additional fossil-fuel generation during periods of high demand. ## A Summer Stress Test Electricity demand reached new highs in several parts of the country. In Texas, the power grid recorded a record peak load of **91.1 gigawatts on July 22, 2026**, according to the U.S. Energy Information Administration. At the time of the peak, solar generation supplied ...

Scientists find a new way to turn water and sunlight into clean fuel.

-
  Scientists Find a New Way to Turn Water and Sunlight Into Clean Fuel What if sunlight and water could become the starting point for cleaner fuel? Researchers at Oregon State University have developed a new family of materials that can use light to help produce hydrogen from water. The research could eventually contribute to cheaper and more practical ways of making hydrogen without relying on fossil fuels. A Different Approach to Hydrogen Hydrogen is already used in industries ranging from chemical manufacturing to refining and fuel cells. But producing hydrogen today often depends on natural gas or on electricity-intensive processes. The Oregon State researchers are exploring another approach: using light to drive the chemical reaction that separates hydrogen from water. Their new material is a type of photocatalyst . When it absorbs light, it helps move electrons in a way that supports hydrogen production. Why the New Material Is Interesting One of the most important features ...

An increasing number of children are arriving in Europe alone — as new UN data shows.

 More and more children are arriving in Europe alone — as new UN data shows A new report by UN refugee and migration agencies highlights a significant trend in Europe: while fewer children arrived via mixed migration routes in 2025, a much larger proportion of them traveled without a parent or accompanying adult. The report was jointly produced by the International Organization for Migration (IOM), UNHCR, and UNICEF, covering child arrivals via land and sea routes in several European countries, including Italy, Greece, Spain, Bulgaria, Cyprus, and Malta. Fewer arrivals, but more children traveling alone According to the new data, approximately 31,100 children arrived in the European countries covered during 2025. This represents a decrease of about 25% compared to the 41,700 child arrivals recorded in 2024. However, another figure stands out. Around 20,800 children—67% of all arrivals—were recorded as unaccompanied. In other words, while the total number of arriving children has dr...

South Korea bets $747 billion on a greener economy.

-
  South Korea Bets $747 Billion on a Greener Economy South Korea has announced one of the world's largest long-term plans to transform its energy system and reduce industrial emissions. The government has unveiled a strategy worth around 1,000 trillion Korean won, or roughly $747 billion , covering the period through 2035. The plan is designed to expand renewable energy, modernize major industries, and turn the transition to cleaner energy into a new source of economic growth. A Green Transformation The program, known as the Korea-Green Transformation (K-GX) , combines government spending, climate finance, and private investment. The government plans around 200 trillion won in fiscal spending , more than 790 trillion won in climate-related finance , while the private sector is expected to pursue projects worth about 220 trillion won . The goal is not simply to produce more clean electricity. South Korea wants to change how some of its most important industries operate. Renewable En...

**The World's First Nuclear Clocks Are Now Ticking**

-
  The World's First Nuclear Clocks Are Now Ticking For decades, atomic clocks have been among the most precise instruments ever built. Now scientists have reached a new milestone. Research teams in Vienna and Beijing have independently demonstrated the first operating nuclear clocks , creating a new approach to measuring time that could eventually transform precision science, navigation, and advanced technology. What Makes a Nuclear Clock Different? Today's most precise atomic clocks measure changes in the energy states of electrons around an atom. A nuclear clock takes a different approach. Instead of using the electrons, researchers use a transition inside the nucleus of an atom . The experiments use the isotope thorium-229 , whose unusual nuclear transition can be reached with laser light. This gives scientists a new and potentially more stable reference for measuring frequency and time. Why Is This Such a Big Deal? Accurate timekeeping is not only about knowing what time ...

A planet born

  A Planet Born After Its Star Died? The Phoenix World That Is Challenging Astronomy Astronomers have found evidence for an extraordinary possibility: a giant planet may have formed from the material released when its parent star died. The object orbits the white dwarf HS 0209+0832 , a hot stellar remnant in the constellation Cetus. Scientists believe the system may contain a so-called second-generation planet — a world that formed from material expelled during the star's later life rather than from the original disk that surrounded the star when it was young. A Planet With a Strange Origin Most planets we know about formed early in the history of their planetary systems. Our own Earth, for example, formed from material left over after the Sun was born. This is what astronomers call a first-generation planet. The new candidate may have a very different story. HS 0209+0832 is a white dwarf , the dense remnant left behind after a star has exhausted its nuclear fuel and lost its oute...

L'IA si sta avvicinando al tuo PC: cosa significa il nuovo approccio di Microsoft

-
  AI Is Moving Closer to Your PC: What Microsoft's New Approach Means Artificial intelligence is gradually moving from the cloud into the personal computer. Microsoft has announced new AI-focused developments for Windows PCs, including technology designed to make it possible for more AI models and autonomous tasks to run locally on compatible computers. The company is also introducing new security mechanisms designed to isolate AI operations from sensitive information on the device. The shift is important because most AI services today depend heavily on powerful data centers. Moving more processing to the PC could change how people use AI for everyday tasks. From Cloud AI to Local AI For years, many AI applications have depended on remote servers. A user sends a request to the cloud, the model processes it, and the result comes back to the device. Local AI works differently. When an AI model can run directly on a personal computer, some tasks can potentially be processed without se...
