Calvin Duncan's life took a dramatic turn when he was sentenced to life in prison for a murder he claimed he didn't commit. Behind bars, he found his calling as a self-taught lawyer, helping fellow inmates fight for their freedom. His dedication paid off when he was released after 28 years, and his
Fish live in water. This water is full of germs. Fish are born ready to face these germs. They have a built-in defense system. This system is always on guard. It is called the innate immune system. One of its key weapons is tiny proteins called antimicrobial peptides, or AMPs. These AMPs help fish f
Fish farming can be a tough business, especially when it comes to keeping nets clean. Biofouling, or the buildup of unwanted organisms, is a big headache. It makes nets heavier and messes with the water flow, which can stress out the fish. Usually, farmers clean the nets or use special chemicals to
Fish can be very sensitive to changes in their environment. Two types of fish, Colossoma macropomum and Piaractus brachypomus, were put through a temperature test. This was to see how their bodies reacted to a sudden drop in temperature, followed by a return to normal. The fish were kept in water
Fish farming is big business. One key player in this industry is the Cirrhinus mrigala. This fish is popular in aquaculture due to its fast growth and adaptability. But to keep these fish healthy and growing, farmers need to pay close attention to their diet. One crucial nutrient is manganese.
Fish are masters of adaptation, and their visual systems are no exception. Six species of centrarchids, or sunfish, living in different light environments were studied. Researchers looked at how these fish see and communicate using light. They measured things like eye size, gene activity, and how li
Fish populations in England's rivers have been on a rollercoaster ride over the past four decades. Once struggling due to water pollution and changes in land use, these aquatic creatures have shown remarkable improvements. Scientists looked at data from 16, 124 surveys at 1180 sites across England,
Fishing can be tough on the body, and it's not just the injuries that are a problem. It turns out, the pain that comes with the job can also mess with a fisherman's sleep. A study looked into this issue by checking out the sleep patterns, health, and work habits of fishermen from four different plac
Fish maw, a prized delicacy with varying prices and medicinal benefits, can be tricky to identify. Scientists recently combined two powerful tools—Wasserstein generative adversarial networks (WGAN-GP) and spectral fusion—to improve how we recognize different types of fish maw. They collected data fr
