The secret behind the art of shifting sands.

by Athul P Kurian – Do you like to be a social chameleon in life?

Just take a look at this. During my field work in Hesaraghatta, I found something interesting. Chameleons hunt with a lightning fast tongue, and take on the colour of what they touch, which helps them to blend into their surroundings. The colour-changing skin is also used for communication. The layer of pigmentary cells in the skin consists of nanosacle crystals that are arranged in a triangular lattice. The lattice can be tuned to alter the spacing between the crystals, which, in turn, affects the colour of light that the lattice of crystal reflects. You can read about this fascinating process here.

NICE @ Lachen School, North Sikkim

by VS Pragadheesh – Recently, the NICE lab visited Government Secondary School, Lachen, North Sikkim and talked with the young minds of the Himalayas. The long discussion with Pragadheesh covered chemical cues of insects, pollination, hoverflies, sunflowers, horticulture and so on. The students at 2900 metre high were: Sunil Bhutia, Tashi N Lachenpa, Chakey L Lachenpa, Baichung Bhutia, Chewang D Lachenpa, Sonam K Lachenpa, Sudeshna Chetri, Kalawady Manger, Pema T Lachenpa, Tshering C Lachenpa and Tenzing D Lachenpa. All were very much interested about biological and ecological research.  We hope they will continue their interest and preserve and promote the amazing beauty of the Himalayas in their bright futures!
All the best Lachen School!

Insect Walk for Vivriti Education Service

by Hinal Kharva – As a part of Vivriti School’s summer camp, kids got a chance to explore their curiosities on an insect walk at the National Center for Biological Sciences. As soon as they arrived, we could see that their tiny eyes had many questions; “where to look for insects?”, “where do they live?”, “what do they eat?”, “Do all insects bite?”

NICE lab members shared our knowledge about insects’ lifecycles, their habitat, their feeding habits, etc. We also helped children to find insects on campus and gave a task to collect insects from different places. They collected some beautiful butterflies, grasshoppers, bugs, ants, bees, and wasps to name a few. Everytime they found a new insect, they ran to us, asked about the name, and observed its behavior for a while. Children showed kindness towards insects by releasing them back unharmed. Other than solitary insects, kids also learned about honeybees and their colonies in the wild. Here, they learned how social insects live together, and how they collect nectar and pollen from flowers.

At the end, they visited the NICE lab and their excitement was incredible after seeing a small collection of preying mantises, ladybugs, oak moths, hoverflies, and Tephritid fruit flies. They had an opportunity to use a simple microscope to observe how different butterflies carry different patterns on their wings. They were amazed to see under the microscope for the first time. As their curiosity and questions never ended, we tried our best to satisfy their inquisitiveness.

It was really a wonderful, interactive and fun time with the kids. We are thankful to Emily Taylor, Jyotsna Arun and Archana Shetty for organizing this event with us!

Adorable Arachnids!

by Sriraksha Bhagavan – Are you someone who hates spiders or is scared of them? Have a look at these tiny, punk-haired eight-legged guys. They are adorable and cute!!

During my field work at Coffee plantations, apart from the beetle that I work on, something else caught my attention. Jumping from one leaf to another, hunting on tiny bugs around, and hiding behind the leaves, these Salticids kept me amazed!! They are somehow less creepy compared to a Tarantula 🙂

When I got closer to these guys they lived up to their name, with a super quick jump they vanish. I got curious and looked around for more, and each species I saw for the first time is a tiny jewel. They had pretty huge, glossy, beautiful 8 eyes (4 on the front and 4 at the back) that seemed to follow wherever I moved.

The next time you see a jumping spider, do not get scared. It is more interested hunting its prey than biting you!!

 

Sleep and I

[Editor’s Note:  This is a musing by one of our lab members who performed her undergraduate thesis on insect sleep in the lab]

by Sanofer A – Sleep, a state of rest, has been conserved across the tree of life, over a grand scale of time that spans a three and half billion years of life on earth. It is as essential an activity as breathing and eating. All living things possess their own sense of time and are hard-wired for a daily rhythm of rest and activity. As the sun goes down in the west, we enter a state of passivity and then at dusk, we return to the normal life. For a behavior that involves almost 25 years of human lifetime, let alone the cat that sleeps 16 hours a day, (except the suppositions we have about the “primordial purpose” it serves) we do not yet know why all animals sleep despite the risks being involved in the process. It’s like when I go to sleep, I’m literally saying, “Good night! Now I’m going to go lie down in my bed and lose command over everything I know and if you hate me, this is probably the best time to kill me”. Like, you go to bed at night, and later in the morning you find that the person who lies next to you is dead and cold. Isn’t that pretty scary? If I were an alien ( No, not ET or Yoda ) that never knew about sleep, I would probably think it’s a neurological disease where people have these “mind adventures”, called dreams, that sometimes get too real and they wake up screaming, glad it wasn’t real. And then they would drink a lot of coffee.

Jokes apart, sleep means different things to different people. For some, it is an escape from reality. For others, it is an opiate that helps them forget their troubles for a little while. For some others, sleep is oblivion. And for me, sleep is God. Like they say, it is really the best of both worlds you can get. And now I leave you with a little poem that I wrote this morning at 3.30 AM (Yes, I’m an insomniac who works on sleep behavior in insects).

Shannon and I

Interested in the fly

Are on a mission

To figure out the sleep definition

Don’t you think that

This is about

Sleep and I

But about sleep and the fly

So I take a little peep

As they sleep

Probably making some wishes

To escape from the petri dishes

And then we wonder, in their sleep

Do insects dream of six legged sheep?

 

The fact that these

Little flies and bees

Sleep just like us

Never fails to impress

It makes me think a bit too deep

About this enigma called sleep

That exists across the animal kingdom

Sleep, for it gives rise to true wisdom

So breathe in and breathe out

And then think about

“Death, so called is a thing which makes men weep,

And yet a third of life is passed in sleep”….

 

Knowledge – A means of destruction?

By Shivali Verma- The vast database of knowledge amassed from practically the beginning of our existence till today is perhaps our greatest feat. It’s a rather admirable collection of facts and figures that proves useful every time we invent or discover something new. Each time we put forth a theory, it is based on certain underlying principles – things we already know. Evidently, Knowledge is our most valuable asset, but it can also be an intimidating weapon. A weapon that can be used against ourselves too, depending on how we use the information at our disposal.

There is so much that has been created at the hands of humans using our knowledge that harms more than it helps. So many examples of our information being used in the wrong way. But the matter in question is this: we know that a nuclear bomb will kill thousands and leave deadly background radiation. We know that polythene bags, if not recycled, are non-biodegradable and pollute our environment. Then why, knowing the ill effects, are we creating such things that will eventually be catastrophic for us? The race for survival is already such a cumbersome process, why would we intentionally make it any harder for ourselves by inventing such things?

My answer to this question is the following.

Every leap humankind has made through history has always been accompanied by its own problems. With advancement, comes a tradeoff. We gain something and take a step forward but also lose something and take a step back. For example, the Industrial Revolution meant the beginning of machine usage and development of technology and transport systems. But it also brought a drastic population explosion, increased child labour and widespread epidemics. To take a far simpler example – locomotives. With the invention of fuel driven locomotives, we found a convenient means of transport that took less manual energy, but resulted in using precious fossil fuels and polluting the air. In other words, it is impossible to create something that has only a positive effect. Even though we know this, we try to invent new things and progress, hoping that in the big picture, the benefits we reap of an advancement outshine its disadvantages. However, whether the pros of something overpower its cons is largely a personal opinion and is swayed by the viewer’s private interests. And so when one person’s (or one species’) idea of ‘profitable’ contradicts the truth of whether it really will be in the long run, our knowledge becomes a weapon as we use it to create something detrimental for ourselves – as is the case with the story of our dear old plastic bag!

With our knowledge behind us, we have built iron and concrete mountains, unimaginable contraptions, foraged our way through forests, fought diseases, waged wars and unraveled some of the deepest mysteries of our universe. Knowledge really is power. But until we become far-sighted, until we account for the possibly crippling consequences that come with a new advancement and learn how to cope with it, we will continue to use our knowledge as a weapon against our own survival as we create disastrous things. Until we fix this fatal flaw we have, we stand at the bow of a ship headed towards calamity. We must change the way we evaluate a situation, act maturely and learn to think ahead of what is currently the norm if we wish to keep our information in the form of a boon instead of a bane. And this is imperative, because without our knowledge, we are nothing.

I will find you and I will kill you: Assassin Flies!

by Santosh Rajus – Coffee White Stem Borers are one of the most elusive and devastating pests of coffee plantations. They are good at hiding and escaping, making it really hard to spot them. It took me almost two seasons to spot a few in the open plantation. Most of the people in the plantation told me that these beetles are really fast and very good at hiding. Hence, they have very few predators, or, in fact, have no successful predators at all.

Walking along the plantation, I just wished to see a few more and, Bam! Something flew fast in front of eyes. Another insect followed it and immediately pinned it down on the wood log. Out of curiosity, I followed it and it was the Assassin fly, also called as Robber fly. It caught the beetle in the air and pinned it down, killing it in a few minutes. What a beauty – this insect will definitely rob your heart! In India, we have been working for more than 100 years on these beetles to find a solution to reduce the pest, but I guess nature already has the best solution 🙂 We just messed it up big time by changing their ecosystem completely.
