Fluoride in water has been a hot topic for over a century. It all started when scientists noticed that people in certain areas had fewer tooth problems. They found that these areas had fluoride in the water. Adding a little fluoride to water can prevent tooth decay, but it's not that simple. Some pe
In Ethiopia, where food and water are often scarce due to weather and droughts, the Bowa Dayole masonry gravity dam is set to irrigate nearby farmlands. However, the dam's foundation is made up of complex geological formations, including highly fractured and weathered aphanitic basaltic rock, and we
You know how energy and water are like best friends? They both help us live and grow. But sometimes, we use too much water to make energy. This is a problem in Northeast China, where old factories use lots of water. Scientists studied the "water footprint" of energy there. They found that while the
Cleaning wastewater usually means creating more waste, especially when it comes to antimony. This stuff is dangerous and can cause real harm to the environment. So, scientists came up with a new idea. They used light and a chemical called sulfite to turn antimony into something useful. This method i
NASA has big plans to return to the Moon by 2026 with its Artemis II mission. But before that, they’re sending two missions to the lunar south pole to search for resources. One of these missions is Lunar Trailblazer, a satellite that's going to study water on the Moon. Scientists think there might b
Storms can be tough on city channels, especially when urbanization changes how water flows. We've been using rules called the Unified Stormwater Sizing Criteria (USSC) to manage this, but it turns out they might not be keeping channels safe from erosion. So, let's dig into how we can do better. Fir
Volcanic areas are some of the most active places on Earth, but we don't understand them very well. Let's look at the central Cascade arc in the USA. Here, water and landforms change together in a systematic way, linked to how old the volcanic rocks are. At the Cascade crest, where there's a lot of
Water scarcity is a growing problem that will affect half of the world's population. It's not just about having enough water; it's about how it affects our health and daily lives. When water is scarce, people get sick from water-borne diseases, don't have enough to eat or drink, and can't work or go
People have long been concerned about water treated at the Fukushima Daiichi Nuclear Power Station. Let's take a step back and see how these worries have changed over time. Back in the day, when news first broke about the treated water from Fukushima, folks were really concerned. They wondered what
Imagine if you could have a fleet of underwater robots that could talk to each other safely and work together efficiently. That's exactly what a new scheme called Energy-Efficient and Trust-based Autonomous Underwater Vehicle (EETAUV) is designed to do. This scheme is made for 6G-enabled underwater
