Bizarre patterns, vibrant colours, heady scents — flowers present a buffet of choices to draw pollinators. In fact, studies have shown that bees, butterflies, and other pollinating insects have particular preferences in the flowers they visit. What’s more, they also tweak their tastes according to the changing environment.

Astronomers detected a planet outside our Solar System orbiting a star like our Sun, for the first time in 1995. Known as ‘exoplanets’, the theoretical understanding of the formation of stars had long pointed to the existence of such worlds. Before 1995, astronomers had claimed to discover exoplanets, but it was difficult to confirm these discoveries. Later, it turned out that one such claim, made in 1988, was indeed correct. However, the discoverers of the exoplanet in 1995, Michel Mayor and Didier Queloz received the Nobel Prize in Physics in 2019.

In the animal world, finding a mate, protecting territory and fending off competitors who vie for love are defining moments. Only those adept at the needed skills for these ‘do-or-die’ circumstances survive, reproduce and thrive. A few animals go the extra mile—sing a romantic song, flash their colours to scare competitors and also woo their mate, some chirp high loud to stand out in the crowd and some, like the dancing frogs, shake a leg!

Fireflies, also called jugnoo in Hindi are fascinating creatures that glow in the dark with unique patterns. Even though they are called ‘fireflies’, scientifically they are considered beetles from the Lampyridae family. The light that we see coming out of these insects is the result of bioluminescence, a phenomenon where an organism emits light through a chemical process.

Carnivorous plants may not be the first thing that comes to one’s mind when thinking about plants. But, these mysterious plants are a fantastic example of nature’s way to adapt to different environmental conditions.

Our body has a personal army of dedicated soldiers ready to defend us all the time—our immune system. Its combatants can fend off simple infections like a common cold or a sore throat, as well as life-threatening intruders like Mycobacterium tuberculosis, the bacteria which causes tuberculosis, or the virus that causes hepatitis. However, sometimes, the cells in our immune system go berserk and find an enemy within—they start attacking cells in our body!
