Hello friends, Welcome back. TIGER : At first as we think of this creature, our mind fills with fear from this enormous gigantic dangerous predator. But if we think for a moment then we realize that not this creature is dangerous for us but we are proving dangerous for the existence of this creature. At the turn of the 20th century, according to sources, India had an estimated 40,000 tigers in the wild. In 2002, based on pug mark census, this number was 3,642. As per the monitoring exercise by Wildlife Institute of India in association with National Tiger Conservation Authority (NTCA), Government of India using camera traps, in 2008 we were left with only 1,411 tigers. This number is so small that they will be gone soon if we don’t wake up to the crisis. The tiger is not just a charismatic species. It’s not just a wild animal living in some forest either. The tiger is a unique animal which plays a pivotal role in the health and diversity of an ecosystem. It is a top predato...

Hello friends, Welcome back. Today I am going to tell you about one more new discovery in the field of science. It is a quite amazing discovery and a very useful one also Electronic components that exploit the phenomenon of superconductivity could allow us to study the collective behaviour of large numbers of neurons operating over long timescales. That is the finding of scientists in the US, who have shown how networks of artificial neurons containing two Josephson junctions would outpace more traditional computer-simulated brains by many orders of magnitude. Studying such junction-based systems could improve our understanding of long-term learning and memory along with factors that may contribute to disorders like epilepsy. The human brain consists of some 100 billion nerve cells known as neurons, each of which receives electrical inputs from a number of its neighbours and then sends an electrical output to others – a process known as "firing" – when the sum of its ...
