Imagine streaming a movie through your tube light or accessing the Internet through a street lamp. Light Fidelity (Li-Fi), a new communication system developed by Professor Harald Hass, can actually achieve this!

Our genes affect every aspect of our lives, from the way we look to the diseases we get. However, they don't act in an isolated manner, because we are also affected by the environment we live in. Our diet, exercise levels, pollution levels in the place we live – all affect what happens to our bodies.
How do scientists proclaim an ecosystem like the Western Ghats as an ‘biodiversity hotspot’ and push for its conservation? They do so by ‘ecological sampling’, a technique used to find diversity and abundance of animals and plants in a habitat. They collect samples of plants and animals from different locations within an area and extrapolate the possible biodiversity that exists in the area.
If someone came up to you and said the stool from one person can be used as medicine to treat another, you’d most likely be disgusted or find it absurd. It sounds incredible, but it is true.
Mosquito bite! That’s all you need to express your killer instinct. But this allegedly innocent, tiny little arthropod with jointed legs, dressed in black and white stripes like an escaped prisoner, bites just for its ‘daily blood’. However, things aren’t quite limited to just blood sucking; this temporary parasitism is increasingly responsible for the transmission of a number of life-threatening diseases. Temporary parasites because mosquitoes suck blood from the host and then leave the crime scene, if alive.
Genetically Modified Crops are those whose genetic makeup has been altered by introducing a foreign gene into its system. This is a popular technique to get the best of both worlds; we retain the desirable traits of the original plant and introduce new beneficial traits from other plants.
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.
