The excruciating pain of having a failed organ and the grim chances of replacing it is a struggle of millions of patients across the globe. A ground-breaking discovery in this field, is giving a whole new definition to having one’s own personal organ! This discovery is none other than tissue engineering -- a science that has changed the face of organ transplant.

Neutrinos are the elusive sub-atomic particles in the Universe. They are abundant throughout the universe and tens of thousands pass through our body every second!
It’s the 20-20 cricket world cup finals. Indian vs. Pakistan! India need 4 runs to win! Yuvraj Singh swings his bat and it’s a…! Blank! Oh no! A power cut!
But wait! Isn’t it the electricity that has been cut? Why then the term “power” cut? Is electricity and power the same? Then why do we get electric shocks and not power shocks?
Evolution has equipped us with ingenious stress responses (flight or fight), to maximise our chances of survival against life threatening threats. An adrenaline rush prompted by our brain during threats increases our blood pressure, heart rate and blood sugar levels enabling us to remain alert and respond to threat. Cortisol, a stress hormone released by the brain keeps these levels high as long as the perceived threat persists.
Doing our dirty jobs of clearing animal carcass for generations, extraordinary scavenging birds of prey, the vultures, deserve our gratitude and attention. Associated with goddesses in Egyptian mythology and revered hero in Indian mythology as Jatayu who sacrificed himself to save Sita, and once commonly seen; today, most species of vultures face extinction worldwide. Four out of nine species of vulture in India are critically endangered; it is now crucial to understand this often overlooked ecologically important bird.
Most of us have seen diabetics take insulin injections. Wasim Akram was an insulin dependent diabetic, and at the same time, a threatening fast bowler.
Insulin is a protein produced in our bodies by the pancreas. In earlier days, insulin was extracted from the pancreas of cattle, in a tedious process that yielded just a few micrograms per pancreas.
Have you ever stepped outside and looked up at the sky on a clear, summer day and noticed something swimming in your field of vision? Little transparent worms or blobs that seem to disappear whenever you try and get a closer look at them, only to reappear as soon as you shift your glance. These are ‘floaters’, or as the scientific community calls them- ‘muscae volitantes’, which is Latin for ‘hovering flies’.
Have you ever received an electric shock while operating everyday electronic devices? Ever wondered why? One of the most probable reasons could be faulty earthing.
The term earthing is not as intriguing as it sounds, for it does in fact involve a connection to the earth. It is a safety installation, which involves connecting the non-electricity carrying part of an electrical system to the mass of the earth so that any electrical energy that gets built up in this part is discharged to the ground.
Are you a fan of detective TV shows? If so, you will know of DNA Fingerprinting as a tool to identify a criminal.
Everyone’s DNA, much like a fingerprint, is unique. Repeating sequences of DNA called tandem repeats are present between genes. The number each repeat sequence varies from person to person. We can generate a unique pattern of tandem repeats for every person using specialized laboratory techniques. Identical twins are an exception to this case since they have the same DNA fingerprint.
