Magnetic Magma earth
Super-Earths are rocky exoplanets more than three times the size of our planet, with far greater internal pressures and temperatures. For years, scientists assumed that if these worlds had magnetic fields, they would form the same way Earth’s does — through movement in a molten iron core. However, new laboratory experiments suggest something very different may be happening deep inside these massive planets. Under extreme pressure, certain molten rocks become electrically conductive. When these materials churn and circulate between the core and the mantle, they can generate magnetic fields on their own. This means a super-Earth might not rely solely on its core for protection. Instead, a thick, dynamic layer of magma could act as a natural magnetic shield, powered by internal heat and motion.

An increase in Mediterranean climate extremes is recorded by pine trees.
Eastern Spain's pine trees are a silent archive of weather history. Mountain pines used wood rings to record wet and dry years long before rain gauges and satellites were invented. Now, when scientists study those rings, they find a blatant warning.

Orlando experiences a rare prolonged cold as colder temperatures return to central Florida.
Orlando — a city known for warm breezes, sunshine, and mild winter days — has been experiencing a winter chapter more reminiscent of northern states than Central Florida. Residents have been bundled up in coats and reaching for heaters that are typically hidden during this time of year, as what began as a brief burst of cold air has grown into a "frigid, multi-day cold spell." The cold arrived without much fanfare, but it has stuck around for a remarkable amount of time. Forecasters say the chill is likely to last longer than most Floridians can remember. Instead of a brief dip, the thermometer has been well below seasonal norms for several days. Locals are pondering the question of when the temperature in Orlando last dropped to such lows.

Why Earth is round why not plan?
For thousands of years, humans have wondered about the true shape of the world beneath their feet. Early civilizations imagined many possibilities: a flat disc, a giant mountain, or even a floating island. However, careful observation of nature, the sky, and the seas gradually revealed something remarkable — Earth is round. Not perfectly like a ball, but very close to a sphere, slightly flattened at the poles. This shape is called an oblate spheroid. The evidence for this conclusion comes from ancient observations, modern science, and direct images from space.

Ancient Rocks Reveal Niobium Origins
On January 23, 2026, researchers from Curtin University announced a remarkable geological discovery hidden deep beneath central Australia. Rare rocks, formed more than 800 million years ago, have revealed the origin story of one of the world’s most promising niobium deposits. This critical metal, now essential for high-strength steel, electric vehicles, wind turbines, and advanced energy systems, owes its presence near Earth’s surface to powerful tectonic events that reshaped the planet during the breakup of an ancient supercontinent.

Severe Weather Conditions and School Closures in the United States
Severe Weather Conditions and School Closures in the United States Severe weather has long been one of the main reasons for school closures across the United States. From powerful winter storms and freezing temperatures to hurricanes, floods, and extreme heat, weather conditions can disrupt daily life and force education authorities to prioritize student safety. In recent years, climate variability has increased the frequency and intensity of these events, making weather-related school closures a recurring concern for families, educators, and local governments. During periods of severe weather, school districts must make difficult decisions, often early in the morning or even the night before, to determine whether it is safe for students and staff to travel. These decisions affect millions of families and raise many questions that people frequently search for during such events. **Why do schools close during severe weather in the United States** The primary reason schools close during severe weather is safety. Snowstorms can make roads icy and dangerous, while strong winds and heavy rain can cause fallen trees, power outages, and flooding. In hurricane-prone states, evacuations and storm surge risks make it impossible to operate schools safely. Even extreme cold can be dangerous, as prolonged exposure can lead to frostbite or hypothermia, especially for children waiting at bus stops. School districts also consider the safety of school buildings themselves. Power failures can shut down heating systems in winter or air conditioning in summer, creating unsafe learning environments. When emergency services are stretched thin due to weather-related incidents, keeping students at home reduces additional risks. **Who decides whether schools should close** School closures are typically decided by local school districts rather than the federal government. Superintendents and district officials consult weather forecasts, transportation departments, and emergency management agencies before making a decision. In some areas, especially rural districts, road conditions play a major role because students may travel long distances by bus. In large cities, decisions may also depend on public transportation safety. While the final call rests with the district, coordination with city or state authorities is common to ensure consistency and public safety. **How early are school closure decisions announced** Parents often want to know how early they will be informed about closures. In many cases, districts aim to announce decisions early in the morning, sometimes before dawn. However, when major storms are predicted, announcements may come the evening before to give families time to plan. Despite advances in weather forecasting, conditions can change rapidly. This is why some districts opt for delays instead of full closures, allowing officials to reassess conditions after sunrise. **What types of weather most commonly cause school closures** Winter storms are the most common cause of school closures in northern and midwestern states. Heavy snow, ice storms, and freezing rain make travel hazardous. In southern and coastal regions, hurricanes and tropical storms are the leading causes, often resulting in closures that last several days or even weeks. Flooding can also force schools to close, particularly when buildings are damaged or roads become impassable. In recent years, extreme heat has emerged as another factor, especially in districts with older buildings that lack adequate cooling systems. **How school closures affect students and families** School closures can disrupt routines, especially for working parents who must arrange childcare on short notice. For students, missed instructional time can slow academic progress, particularly in districts that experience frequent closures. Many schools now rely on remote learning days to reduce learning loss during closures. While online instruction can help, it does not fully replace in-person learning, especially for younger students and those who rely on school services such as meals or special education support. **Are weather-related school closures becoming more frequent** Many people are asking whether school closures are becoming more common. While patterns vary by region, there is growing concern that extreme weather events are increasing in frequency and severity. This has led districts to rethink emergency preparedness, invest in stronger infrastructure, and develop flexible academic calendars that can absorb unexpected disruptions. Some states have adjusted their policies to allow virtual learning days or extended school years to make up for lost time caused by weather emergencies. **How can parents stay informed during severe weather** Clear communication is essential during severe weather events. Most school districts use multiple channels to notify families, including automated phone calls, text messages, and official announcements. Parents are encouraged to rely on direct communication from their district rather than rumors or unofficial sources. Preparing in advance, such as having backup childcare plans and understanding district policies, can help families manage sudden closures more smoothly. In conclusion, severe weather conditions play a significant role in school closures across the United States. While these decisions can be inconvenient, they are made with student safety as the top priority. As weather patterns continue to evolve, schools, families, and communities must adapt together to ensure that education remains resilient in the face of environmental challenges
