Cockroaches and Antibiotics
Glory to Allah Almighty who exploited these cockroaches for our benefit, let us to contemplate …
According to a new research scientists have found that the central nervous systems of American cockroaches produce natural antibiotics that can kill off bacteria andthey reported that they found the same bacteria-killing molecules in a two species of locust. The findings suggest that the “insect world” which makes up 80 percent of all animals on Earth” may be teeming with new antibiotics.
The study co-author Simon Lee of the University of Nottingham in the U.K say”It's a promising new lead. We are looking in an unusual place, and to my knowledge no one else is looking there". "That's what we need in terms of finding new antibiotics, because all the usual places (such as soil microbes, fungi, and purely synthetic molecules) have been exhausted." Lee Added
The team tested nine separate types of antibacterial molecules found in the insects' brains and discovered that each molecule is specialized to kill a different type of bacteria.“This very clever defense mechanism allows the bugs to survive in the dirtiest of domains” Lee said.
Scientists say that insect-brain drugs for humans are still years away and they claim that cockroaches could one day save our life.
Glory to Allah Almighty who didn’t create anything without a purpose as He Almighty says: (And in your creation and what He scattered (through the earth) of moving (living) creatures are signs for people who have Faith with certainty.){Sûrat Al-Jâthiyah- The Kneeling -verse4}
Atheists and disbelievers claim that these creatures were created by the power of nature!!!!! And it has no benefit but Allah Almighty say that He exploited all creatures for our benefit as Hesays 
And has subjected to you all that is in the heavens and all that is in the earth; it is all as a favour and kindness from Him. Verily, in it are signs for a people who think deeply.) {Sûrat Al-Jâthiyah- The Kneeling –verse13}.
