In the world of environmental science, things aren't always as straightforward as they seem. Take zebrafish larvae, for instance. These tiny fish face big trouble when exposed to cadmium sulfide (CdS), a harmful chemical. When sunlight hits CdS, it releases toxic cadmium (Cd2+), which slows down the
Stress is often seen as a villain, but what if it has a hidden superpower? Recent studies on zebrafish reveal that stress can actually boost skin immunity. Here's how it works: when zebrafish feel stressed, a hormone called cortisol kicks in. This hormone activates a chemical called Cxcr4 through tw
The world of toxicology is changing. Researchers have been exploring new ways to test how harmful substances affect living things. One exciting development is the use of three-dimensional (3D) cell cultures. These 3D models are better at mimicking real tissues than the old flat (2D) cell layers.
The world of science has seen a significant shift in the way it studies behavior and brain function. One of the key players in this change has been the humble zebrafish. This small, striped fish has become a star in the world of biological research, particularly in the field of behavioral neuroscien
The effects of oil spills and low oxygen levels on fish are well-known. These stressors can mess with a fish's behavior and how its body works. But what about the next generation? How do these issues impact the kids of affected fish? This is what researchers wanted to find out. They looked at zebra
The number of segments in the trunk of vertebrates varies greatly. This diversity is fascinating, but the process behind it is not well understood. Scientists believe that the number of segments is set during early development. This happens when cells in a specific area, called the pre-somitic mesod
Understanding how cells develop and change over time is a big deal in biology. It helps scientists see and understand the complex ways cells behave during the early stages of life. Usually, tracking cells relies on stable signals and strong promoters, which can be limiting for long-term studies. How
Ever wondered how chemicals in water can affect tiny fish babies? Researchers found something surprising. A chemical called TDtBPP, found in natural waters, can cause big problems for baby fish. This chemical can mess with the development of baby fish, causing them to have birth defects and even di
Cancer treatments often involve powerful drugs that attack both cancerous and healthy cells. This lack of specificity can lead to serious side effects. Researchers have been exploring ways to make these treatments more precise, focusing on unique features of cancer cells. However, finding a reliable
Think you can't quite make out the lymphatic vessels in your zebrafish? It's a challenge that biologists know all too well. Normally, spotting subtle or varied shapes in these tiny creatures can be a daunting task that eats up a lot of time. We've all been there. It's frustrating to spend countless
