“Ecology is boring for the same reason that destruction is fun”, said Don DeLillo, an American novelist and playwright. This saying resonates very well with road ecology. Road kills are soon forgotten till the next one happens, reckless driving in protected areas is ubiquitous and polluting ecologically sensitive area is an act of no shame. And, this is not fun!

The sunscreen lotion is supposedly a magic wand we are always advised to use when going out to protects us from sunburns. However, do we know why we get sunburns? Do we understand the science of sunburn?

They say chocolate is nature’s way of making up for Mondays and that sure justifies its reputation as comfort food. The key component in chocolates is cocoa, a bean that is found in the pods of Theobroma cacao, or the cocoa tree, a native of Central and South America. The word ‘cocoa’ literally translates to ‘Food of the Gods’ in Greek. In recent years, countries in Africa and Asia have assumed a leading role in cocoa production, with Western Africa producing almost two-thirds of the world’s cocoa.

Have you ever admired red skies or criticised early morning haze? Atmospheric aerosols, tiny solid or liquid particles suspended in air, also called Particulate Matter (PM), are responsible for the myriad hues created by the evening sky. Not just that, aerosols impact the global climate and play a role in ozone depletion. These particles generally range from about a nanometre to ten micrometre in size and are either directly emitted or formed by the conversion of a gas to particles.

How cool would it be if we could switch living cells in our bodies on and off just like all our gadgets and appliances? Well, science has made it possible, thanks to all the researchers who thought of this ingenious idea and also made it work. The science of optogenetics uses ‘light’ to play around with and manipulate living cells in tissues, specifically the nerve cells aka neurons in our brains.

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.

Imagine you come home to your city and find no one! While it isn’t very probable in human societies, a similar phenomenon called colony collapse disorder is often found in honeybees. Here, worker bees mysteriously start disappearing from their hives, and that leaves no one to do the housekeeping, nursing and foraging. Hence, the honey bee colonies start collapsing.

I can’t swim. Imagine that you can’t either. Also, imagine that you fall into this big body of water. You are drowning. The water is slowly filling into your lungs. They say it can take from minutes to hours. But, who are ‘they’? ‘They’, who you can see and hear and are on the banks of that big body of water. ‘They’ are standing on the hard surface, while you are trying to grab onto something, or find a footrest somewhere. However, you can’t because you’re drowning, and you don’t want to. Perhaps, ‘they’ also don’t want you to die.

Have you ever chanced upon a tiny spider in your garden, or perhaps on the wall of an old building, that swiftly jumped away as soon as you noticed it? Chances are that you spotted a spider of the Salticidae family. Jumping spiders, as they are commonly termed, are known for their leaping abilities, active hunting behaviour and impressive vision. It is hard to imagine that these wee arachnids have evolved a complex system of signalling using colours.

We are often told that bacteria are dangerous, cause notorious infections and that we need to keep them away. While there is a bit of truth in that, did you know your gut has a plethora of these ‘friendly’ microbes? Yes, our gastrointestinal tract is home to many microorganisms forming an ecosystem called the gut microbiome. They help the digestion process and also contribute to our happiness and other moods!
