Fatty acids are widely occurring in natural fats and dietary oils and they are known to have antibacterial and antifungal properties. However, little is known on the antibacterial and antifungal properties of the blindyour-eye mangrove (Excoecaria agallocha) and this study for the first time determines the fatty acid composition and the antibacterial and antifungal activities of Fatty Acid Methyl Esters (FAME) of the blindyour-eye mangrove plant found along the coastal areas of south India.

A key aim in biology and psychology is to identify fundamental principles underpinning the behavior of animals, including humans. Analyses of human language and the behavior of a range of non-human animal species have provided evidence for a common pattern underlying diverse behavioral phenomena: Words follow Zipf's law of brevity (the tendency of more frequently used words to be shorter), and conformity to this general pattern has been seen in the behavior of a number of other animals. It has been argued that the presence of this law is a sign of efficient coding in the information theoretic sense. However, no strong direct connection has been demonstrated between the law and compression, the information theoretic principle of minimizing the expected length of a code. Here, we show that minimizing the expected code length implies that the length of a word cannot increase as its frequency increases. Furthermore, we show that the mean code length or duration is significantly small in human language, and also in the behavior of other species in all cases where agreement with the law of brevity has been found. We argue that compression is a general principle of animal behavior that reflects selection for efficiency of coding.

A key characteristic of human language efficiency is that more frequently used words tend to be shorter in length-the 'law of brevity'. To date, no test of this relationship between frequency of use and length has been carried out on non-human animal vocal communication. We show here that the vocal repertoire of the Formosan macaque (Macaca cyclopis) conforms to the pattern predicted by the law of brevity, with an inverse relationship found between call duration and rate of utterance. This finding provides evidence for coding efficiency in the vocal communication system of this species, and indicates commonality in the basic structure of the coding system between human language and vocal communication in this non-human primate.

In response to the coronavirus pandemic, several countries have imposed curfews, quarantines, and lockdowns to restrict the spread of the infection among people. India had initiated a nationwide lockdown to combat the pandemic starting from the last week of March until the end of May 2020. But, the lockdown had continued subsequently in several red zones across parts of the country for few months. However, scientists have criticized the government's abrupt lockdown since it prevented people from preparing for the worst aftermath. Besides, the curfews have blocked millions of impoverished migrant workers from leaving cities to return to their homes in distant rural villages. As a result, the destitute workers have endured enormous hardship and outright discrimination desolately leading to their added physical and mental distress, pain, suffering, and death. Most of the victims of the lockdown have belonged to the economically distressed lower social classes of the Indian caste hierarchy. This article outlines their sufferings triggered by the long drawn-out lockdown episode.
