3. What is an Asteroid?
NASA's Jet Propulsion Laboratory consistently forecasted the passage of four asteroids close to Earth.
About Asteroid:
- Asteroids, sometimes called minor planets, are rocky remnants left over from the early formation of our solar system about 4.6 billion years ago.
- Most of this ancient space rubble can be found orbiting the Sun between Mars and Jupiter within the main asteroid belt.
- Asteroids orbit the sun in highly flattened or "elliptical" circles, often rotating erratically, tumbling and falling through space.
- The total mass of all the asteroids combined is less than that of Earth's Moon. Many large asteroids have one or more small companion moons. An example of this is Didymos, a half-mile (780 meters) wide asteroid that is orbited by the moonlet Dimorphos, which measures just 525 feet (160 m) across.
4. What are Statins?
A study by a group of researchers in China has found that administering ursodeoxycholic acid (UDCA) can stave off the tendency of statins to induce glucose intolerance and diabetes.
About Statins:
- Statins are prescription medications that people take to bring their cholesterol down to normal levels. It works by blocking the action of the liver enzyme that is responsible for producing cholesterol.
- Too much cholesterol in the blood can cause a buildup of plaque on the walls of the arteries. That buildup can eventually cause the arteries to narrow or harden. Sudden blood clots in these narrowed arteries can cause a heart attack or stroke.
- Some statins can decrease your LDL(low-density lipoprotein, or “bad”) cholesterol by 50% or more. Providers often call LDL “bad” because it builds up inside your arteries, making it harder for blood to move through them.
- These medicines also have been linked to a lower risk of heart disease and stroke. Statins may also help reduce the risk of certain blood clots.
- Statins can sometimes interact with other medicines, increasing the risk of serious side effects, such as muscle damage.
