Imagine cars that change colors on-demand, or bridges and buildings whose colors reflect the amount of strain or stress applied to them. We would all benefit from such innovation.
Last week, March 12, researchers at the University of California, (UCL), Berkeley, announced the creation of a thin semiconductor film of silicon, 120 nanometers thick, that when flexed or bent can reflect colors on a wide variety of the light spectrum; a color-changing sensor film.
Attempts at creating a color changing sensor is not new. Last year, in a research funded by the National Science Foundation, (NSF), researchers at the same University, but the Riverside campus, created a nanosphere-laced polymer that changes color under stress using gold nanoparticles. What differentiates the silicon film from other sensors is that the range of reflected light is much flexible and the material used was much more permeable to bending or flexing.

The idea behind the invention came from nowhere but nature. They conceived the idea of imitating butterflies and beetles who create iridescent displays of colors.
According to one of the researchers, "the next step is to make this larger-scale and there are facilities already that could do so," said Chang-Hasnain. "At that point, we hope to be able to find applications in entertainment, security, and monitoring."
Cars of tomorrow might respond like a chameleon to its environment, or change to colors reflecting the amount of pressure applied to the body, or in relation to the amount of stress or strain undergone during its lifetime. The possibilities are enormous.
You will not believe it. The house of the world’s number one terrorist, before his death, looks like an everyday house you can find on the streets of Lagos.
It’s not his house actually; just a hideaway in Pakistan.
This series of 21 pictures on Time.com shows a man running away from the world, lost to worldly splendor but surrounded by death, destruction and disaster. A man who had seen his dying days and that of the terror organization he helped to create.
The room has an ordinary bed, common wardrobes and looks like an everyday suburban house.
One would have hoped his hideout was somewhat luxurious; with the wealthy and powerful of Pakistan. Wishful thinking!

Choices are a basic fact of life. Some choices can be a turning point in our lives while some are inconsequential and will only satisfy some ego.
Whatever choice you are making, now and in the future, judge the merits of the possible outcomes of that choice before taking the leap.
Take a look at the picture below. This is a horrible sight. The deed is a barbaric act. The victim concerned has accepted her fate; look at how calm and composed she appears! Justice will never come to her aid. The mob has decided on her. The mob is justice.
This is barbaric, oh Nigerians!Credit: Onlinenigeria.com
That is the face of Nigerian law. The rule of law has vanished. It exists only for the well-to-do. As a Nigerian, who reads the daily news, I understood that the people, our people, are scarred beyond repair, both mentally, physically and emotionally. The stories of crimes that go perpetrated without the criminals getting punished, rather the criminals become victors, is aplenty. The quest for riches and money is beyond imagination.
These and many more reasons have made people to resort to taking laws into their hands.
The rule of law can go to hell, a typical Nigerian on the street will tell you. If you cross check his stories, he’ll turn out speaking the truth.
Does it mean our society should endure mob injustices like this?
No matter the crime she must have committed, as a human, she deserves to be taken to the authorities; handed over to the police. The law should be a constraint upon human behavior and not something to be shunned because the poor and the weak are not protected since they do not have the money to fund a case.
In Nigeria, let respect for human rights be a platform we should be standing on.
