Black coloured cockroach lurking in our school!!

It was late at night last week when Ms Chai Yen was still at work. The constant humdrum tapping of her laptop keyboard was the only sound in the dead silence. When suddenly, what seemed like a sharp rap broke the rhythm and stunned Ms Lim. In front of her very eyes was a strange, black, creepy cockroach.

“I couldn’t believe my eyes,” explains Chai Yen. “I leapt out of my chair and dashed next door to call my colleague. She just managed to shoot a photo of this unusual cockroach, when it darted out of the room like a bullet and just disappeared.”

Since then, there have been no sightings of this unusual species of cockroach.

The Blog squad embarked on an investigation as to what this creature could be. Had Chai Yen really stumbled across a new species of insect? Or is it some weird mutant?

We asked Dr Donny, who specializes in molecular genetics of zebrafish, whether it could be possible to genetically modify and create a super speedy cockroach?

“Theoretically possible, she says. “The method is called transgenesis. What this means is that you inject a gene that produces black pigmentation into the egg of a cockroach. You need to do this for many eggs because the gene may not become integrated (taken up) into the DNA of the cockroach egg.

Even if the gene becomes integrated, it may not be expressed in the adult cockroach. That is, you may not see the black feature. So then you grow many cockroaches and cross them, until one that has the black pigmentation!”

In the mean time, Chai Yen has found another witness who claimed to have seen a pure white cockroach!!

Could it be possible that such experiments are being conducted here in our school in the still of the night? And who is conducting such experiments? An inspection of the laboratories revealed no such evidence. Only the genetically modified zebra fish were seen glowing in the darkness.

However, such highly classified information would be cleverly concealed. The Blog Squad also learnt from lab staff that doors could sometimes be heard slamming at night despite all labs being locked and empty. Furthermore, stray vials of restriction enzymes and a flask of virus culture were found lying around in one of the labs.

According to Meng Chuan, one of the TSO’s who has extensive experience in biotechnology, the particular strain of virus that was found could have been used to tranfect insect cells. “The restriction enzymes are used to cut DNA. The pieces can be inserted in the virus that is then used to infect the cells.

“However, the incident is strange,” added Meng Chuan. “The virus is kept under lock and key and only the lab-staff has access. As far as I am aware, no-one in our lab is doing work with this particular virus.”

In a recent development, the photos were shown to an MB (Molecular Biotechnology) student, Joanne, who is also very proficient in IT matters, having completed an elective in digital media. She is of the opinion that the photos are not genuine and the so called black cockroach has been inserted by photoshop!


Why then would Chai Yen have fabricated such an extraordinary tale! So far, no clear motive is apparent for this action.


The matter is still being investigated.
