Plasma is a type of ionized gas consisting of a mix of positively and negatively charged particles. It is the fourth state of matter, after solids, liquids and gases. Plasma is found throughout the universe in stars and gas clouds and makes up most of the visible matter in the universe. Plasma is used in a variety of industrial and scientific applications, including welding, plasma cutting, plasma etching and plasma displays. It can also be used to create fusion energy, which is necessary to sustain life on Earth. Plasma is a powerful tool for studying the behavior of matter in extreme conditions. Scientists use plasmas to study astrophysical phenomena, nuclear fusion, and the properties of materials. Plasma is also being explored for use in medical treatments, such as plasma therapy for cancer and other diseases. In this section, we have gathered news, articles and videos about plasma from around the world, including the latest developments in plasma research and applications.
We studied the effects of Toxoplasma gondii on wolf behaviour in Yellowstone National Park, Wyoming, USA. We found that seropositive wolves were more likely to make high-risk decisions such as dispersing and becoming a pack leader, both factors critical to individual fitness and wolf vital rates.
Hubble observations have revealed a string of super-hot blobs, each with a temperature of more than 17,000 degrees Fahrenheit, being ejected from a dying star. Great balls of fire! NASA's Hubble Space Telescope has detected superhot blobs of gas, each twice as massive as the planet Mars, being ej
First-of-its-kind experimental evidence contradicts traditional theories about the emission and absorption of radiation by plasmas. While solids, liquids, and gases are familiar states of matter, there is a fourth state called plasmas which is the most common form of matter in the universe. It can
