Scientists claim to have found the

By studying frog eggs, the researchers measured the rate at which cells killed themselves when they "committed suicide" for the benefit of body parts.

Name : Speed ​​of death.

Age : Actually this is not very relevant.

Appearance : Cell

Why say this way? Because you're going to have to read some unpleasant scientific knowledge.

Don't go round and go into the main problem. Are you ready Two systematic biologists of Stanford University, Xianrui Cheng and James Ferrell, have found the "speed" of cell death.

What is a system biologist? A biologist and also very good at math, but this is not really something you need to care about.

So what do I need to care about? If we know how cells die at a rate, and more deeply, how they die, we will be able to do great things.

Like what? Oh, you know, cure cancer by "encouraging" cancer cells to kill each other, or prevent the cells of Alzheimer's patients from dying.

What is the speed of death? According to Cheng and Ferrell, is 30 micrometers a minute .

Micrometer, I don't seem to have heard this word ever. It's easy to understand, because this unit is very small and rarely used in practice. Micrometer, often referred to as micron, equals 1 * 10-6 meters, one millionth of a meter or one millionth of a millimeter.

So the speed of death is 30 millionths of a millimeter per minute? Exactly. To make it easier to remember, New Scientist pages have been converted into two millimeters per hour.

What exactly does that die at that speed? Cell. By studying frog cells, Cheng and Ferrell measured the speed of "apoptosis" ( cell death), which could be interpreted as "pre-programmed death" of cells, when cells "themselves." close " for the benefit of body parts. Sometimes the cells will feel for themselves that it is time to leave; At other times, "neighbor" cells will give them a push with trigger waves. Cheng and Ferrell measured the speed of those waves.

Is the cell death good or bad? Mainly good . On average, people lose about 50 billion cells a day, and you can see that we still live well. However, there are times when cells become "bewildered" , the cells need to die while the bad cells live, the more we understand the cell death process, the Medical cards will be more effective.
