When guests come, we as humans offer them all food and facilities with much hospitality. Then it is needless to to say how much hospitality will be there for those visitors who bring with them some advantages for us. Such a hospitality exists in plants also. Sacred Lotus (Nelumbo nucifera, 'Thamarai' in Tamil) exhibits it to the visiting bees.
In our human life, at each phase of our age we have our own best performing activities. Equally, at the same time we have also the impairment of our other activities that we did well in our earlier phase! Such an activity is the impairment of close print reading (viewing) ability of the eye, called as Presbyopia. When I was a school student my mother had given me often thread and a stitching (sewing) needle to thread through the needle's eye for her.
Diabetes, as you know, has now become a global disease affecting human lives in many countries. It is related to Obesity: obese people are more prone to develop Diabetes. So far, the reduction of obesity has been tried with risky surgical operations. Now, a non-surgical treatment for it has been devised. It aids also in reversing Diabetes (Type 2) that has its onset in a person just now!
Usually humans learn from animals and use those animals' technologies in machines, such as airplane etc. A bony fish uses a tactic to catch its prey that we humans use! It fishes(!) with an angling rod and a bait as we do in angling! The fish is the Anglerfish (Frogfish). It has a fleshy 'rod' hanging from its head that serves as a bait to lure the preys into its mouth and devour.
A different thing having unusual size, color or movement attracts always our attention towards it. A tiny bird with black color and jerky flights is an example for it. It is the Indian Robin (Saxicoloides fulicatus, 'Kallukkuruvi' in Tamil). It is found in open grounds perching on rocks, hopping around and catching insects. It keeps its tail always up; but occasionally wags it down.
