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.

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.

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.

Earlier this month, we erred. Among the 1000+ articles published on Research Matters, it was the first for us. An alert reader expressed displeasure on Twitter with a hashtag #fakescience on one of our stories. Alarmed, we investigated to note that the story was based on a research paper published in a journal listed as ‘predatory’, and with that, found a lot more about the prevalence of ‘predatory’ journals that hound the world of science.

The words ‘insect migration’ bring to mind the vibrantly coloured monarch butterflies, making their way from Mexico to the south of Canada by the tens of thousands. Less conspicuous but just as spectacular is the migration that takes place across the Indian Ocean, which is believed to be the longest insect migration ever recorded.
