Copper and tungsten can boost the performance of a catalyst called alpha-iron oxide. This catalyst is used to clean up nitrogen oxides from the air. It works by using ammonia to break down these harmful gases. This process is known as selective catalytic reduction. The goal is to make this process w
There is a well-known drug called doxorubicin. It is used to fight cancer. However, it can harm the heart. This is a big problem for patients. Doctors have found a solution. It is a substance called dexrazoxane. This substance can stop the heart damage caused by doxorubicin. Dexrazoxane works in an
The world of organic chemistry is buzzing with excitement over a new type of catalyst. This catalyst uses visible light to drive chemical reactions. Most of the focus has been on oxygen and nitrogen-based catalysts, like acridinium and pyrylium salts. However, sulfur-based catalysts have been largel
Easter is a big deal. It is a holiday that brings people together all over the world. This year, something special happened. People from the East and the West celebrated Easter on the same day. This doesn't happen often. It only occurs every three to four years. It is a rare event that shows how dif
Mitochondria are the powerhouses of cells, and they are always changing shape. Why they do this has been a mystery. Scientists looked at yeast cells growing in different foods. They found that the shape of mitochondria and their activity do not go hand in hand. Cells can have different mitochondrial
The body is a complex machine. One of its key workers is a molecule called hydrogen sulfide. This tiny molecule plays a big role in keeping the body running smoothly. It is involved in many processes, from regulating blood flow to fighting inflammation. However, how it moves around the body and send
Insulin is a crucial player in how our bodies handle sugar. It sends signals to our muscles to absorb glucose from the bloodstream. For a long time, scientists thought insulin boosted the production of hydrogen peroxide in muscle cells. This would then tweak certain proteins, affecting how insulin w
Greek Orthodox Lent is a significant period of fasting. It lasts for about 40 days. During this time, many followers adopt a vegan diet. This diet excludes all animal products. It is similar to a vegan diet followed year-round by some people. This diet can have effects on the body, especially the gu
Heat waves are becoming more common. These high temperatures are a big problem for crops. They can really mess up how plants grow and develop. This is a huge issue for farmers all over the world. Plants have tiny helpers called microRNAs. These microRNAs play a big role in how plants grow and react
Tesla's popularity has grown but so has the hate towards the brand. In Lowell, Massachusetts, a Tesla owner had a scary experience. He was driving down Jackson Street when he heard rapid gunfire. He saw a man holding up his hands, and then the shots rang out. The Tesla ended up with two bullet hol
