Our cells are programmed to die!

An experiment conducted back in 1965 by Dr. Leonard Hayflick, show that our cells have a molecular clock, which starts ticking from the moment we’re born. That clock determines our cells’ life span, and hence our death!

According to his investigation (Hayflick limit), humans can only possibly live up to 120 years old since our cells are programmed to die. All of our cells undergo a process called apoptosis, which is their programmed cellular death. At some point in our lives our cells are all programmed to go through apoptosis and not regenerate!

If our cells weren’t programmed to die, we would all have cancer since they would all just grow without having anything to stop them!Therefore, be grateful for apoptosis, and stay in school.

Video of the Day : Mosquito Biting from the Inside

As you can see in the video below  the mouth parts contain multiple parts that diverge once entering flesh. Four of these — a pair of mandibles and a pair of maxillae — are thin filaments that help to pierce the skin  and the main brown filament is made up of two parallel tubes: a hypopharynx, which emits saliva, and a labrum, which pumps blood back up.

The video was made with a microscope inserted into the skin of an an anesthetized mouse, which was then fed upon by malaria-infected mosquitoes. You can see the mosquito searching around before finally hitting a vein. 

Sun's Magnetic Field Flip Won't Doom Earth, Scientists Say

We have nothing to fear from the big change that is about to occur on the sun, researchers stress.
The sun's magnetic field is set to reverse its polarity in the next few months. But the shift won't spark an increase in powerful solar storms or other events that could have a damaging effect on Earth and its inhabitants, researchers said.
