Learning Laziness from Ants

Ants have always been the epitome of industriousness and team work.  Since childhood, we have been fed with stories where ants put in the hard work and are well rewarded in the end for their effort. Time and again, ants save the day because they are hard working. Ask the lazy grasshopper, if you do not believe me. But, that's not completely true. In a recent study published in Science Magazine , researchers at the Georgia Institute of Technology, studied burrowing techniques of ants and found that 30% of the ants actually do the work. This might just be the reason, you have been looking for, to justify your lazy attitude but before you harp on it, do read this post to know why ants do so.  Like humans, ants, too, are social insects and do their work collectively.  Division of work is common phenomenon in the ant society and so is movement of individual units to and fro from home to place of work. Problems of the social structure should affect ants in equal measure as they a

What is eDNA and can we find the Lochness Monster?

Recently, an international research team led by University of Otago’s Professor Neil Gemmell made headlines by announcing that they would be looking for signs of the Loch Ness Monster's DNA. While the work seems fanciful, the science being used is very real. Scientists, researchers, and businesses are using a new technology known as environmental DNA (eDNA) for a number of applications beyond the hunt for a mythical creature, like detecting hard-to-find species in aquatic ecosystems and determining the prevalence of said species, without having to trap or visually count the animal.   eDNA works by taking advantage of a simple fact: as living organisms move through their environment, they shed genetic material in the form of DNA. This material lingers, providing insight into the past and present of the creature that left it behind.  eDNA can tell us quite a bit about, without actually having to see things to believe them According to an article in Scientific A
