Plants have a clever way of responding to their environment. They use special chemicals called hormones. Two of these, abscisic acid and strigolactones, come from a substance called beta-carotene. Abscisic acid helps plants handle drought and keeps seeds from sprouting too early. Strigolactones, on
In the world of spinal cord injury (SCI) rehabilitation, leg stretching is a common practice. However, its effects on recovery are not fully understood. Recent research has shed some light on this topic, focusing on rats with a specific type of SCI. This study looked at how leg stretching affects bo
The universe is full of surprises, and one of its biggest puzzles has finally been cracked. For a long time, scientists have known that ordinary matter, the stuff we can see and touch, makes up only a small part of the universe. But where is the rest of it? This question has baffled astronomers for
The brain is a powerful tool that can create a detailed map of the world around us. This map helps us predict what will happen next, based on what we've experienced before. When we're not focusing on anything in particular, our brain goes into autopilot. It starts replaying these experiences, just l
The Milky Way galaxy is a vast, spiral-shaped collection of stars, gas, and dust. It stretches about 100, 000 light-years across and includes our solar system among its many inhabitants. Our solar system takes roughly 250 million years to complete a single orbit around the galaxy's center. The name
Dark matter is a big mystery in space. It makes up most of the universe, but scientists can't see it or figure out what it is. Some scientists think that dark matter might be clumping together and acting like lampshades. These "lampshades" could drift between Earth and distant stars, making them loo
The human body is a bustling network of cells that constantly communicate with each other. One way they do this is by releasing tiny packages called extracellular vesicles, or EVs. These are tiny bubbles of fat and protein that float in the blood and other body fluids. They play a big part in keepin
Liver cirrhosis is a serious health issue that often gets worse over time. It is a major problem worldwide, and finding ways to stop or reverse it is crucial. One promising solution is hepatocyte growth factor, or HGF. This substance is known for its ability to help the liver regenerate and reduce s
Tractography is a complex process. It can be influenced by many factors. These include the quality of the data, the choices made by the operator, and even biological differences. Noise and motion can also play a role. Even small decisions or overlooked details can lead to big differences in the
Gastrointestinal stromal tumors, or GISTs, are a type of tumor that can grow in the digestive system. These tumors can occur in both dogs and humans. They are often linked to changes, or mutations, in a gene called KIT. Scientists took samples from 55 cases of canine GISTs. They looked for spec
