Vocal learning might involve imitating sounds or producing completely new vocalizations. Nearly all mammals on Earth make some vocal sounds, and the vast majority are born with innate abilities to do so. But humans are not: We need to learn how to speak. While many studies over the past century have helped explain how we understand language, the mechanisms behind how we process and learn to make the sounds that allow us to express language are not well understood. So, it is important to understand the neurobiological mechanisms underlying vocal learning and language acquisition in mammals as vocal learning plays an important role in language acquisition.

No second thoughts about the fact that Bitcoin is the most actively traded cryptocurrency of all. Ever since the blockchain and cryptocurrencies became part of the financial markets conversation, Bitcoin has been a market leader. Along the same lines, Ethereum has rapidly moved up in terms of crypto valuation and other applications that are developed on its blockchain. Many tend to believe that it is on the basis of Bitcoin that several applications are run. However, this is not the case. There are a number of applications that run on the Ethereum blockchain – Stable coins, Defi, and NFTs to name a few. As blockchain and cryptocurrencies are gaining immense popularity and their use is bound to diversify, it does make sense that capital will flow to this non-Bitcoin platform. In a nutshell, it is now time that we people from the traditional thinking according to which it is the only Bitcoin that is home to a plethora of options, should not be conclusive yet on what the future holds as far as blockchain and cryptocurrencies are concerned.

When the world first heard that Russia had used Facebook ads in an attempt to interfere with the U.S.’s $2016$ elections, computer scientists and cybersecurity experts heard a call to action. For the past three years, we have been studying how hate and disinformation spread online so that independent researchers can build stronger defences to protect the public. But as we have raced to conduct this basic science, we have met steep resistance from the primary platform we study: Facebook. Our own accounts were shut down last month, another sign of the social media company’s rejection of scrutiny.
