giant luminous shark

The article that I read this week was called "'Giant luminous shark': researchers discover three deep-sea sharks glow in the dark" written by Elle Hunt. The text was about lately discovered sharks with the ability to glow. 

Finding out about such a surprising thing isn't really a surprise. It is common knowledge that we didn't discover the whole marine life that exists. There is still a lot to find out in this ecosystem and we still are slowly getting to know it. Three sharks found near New Zealand's coast only prove that. Like said in the text, I think that the fact that those animals live in the zone which sunlight reaches and still use bioluminescence sheds new light on their lives.  Now scientists have to answer the question of why are they doing it. One of the hypotheses is that those sharks glow to camouflage themselves. I think that it makes a lot of sense because those animals aren't the biggest predators in the ocean and they can easily be eaten.

    How could 'glowing' be a form of camouflage? I'd think it attracts animals.

      I didn't make myself clear. I meant that shark seen from below, by some bigger predators, aren't visible. It glows and this light is kind of bled into the sunlight. So the camouflage works only when the threat is under the shark.

 The article which I read today was written by Peter Rutland. This text is about a significant change in the everyday life of ordinary Russians caused by sanctions. While I understand that all of those limits imposed on Russia are meant to end the war as fast as possible I keep thinking about a common person from Russia facing them. It is obvious that if the country’s economy collapses standard of living there also changes dramatically. Prices are soaring and everyday life isn’t getting harder for individuals but also for all kinds of businesses. I feel pity for those people, mainly because I would be scared if I were in their position. But we have to remember the purpose of sanctions.  Although Russia’s citizens didn’t really hurt anyone they have to feel a change to start protesting and putting pressure on authorities to stop military operations. I think that over time more and more Russians will protest and will demand to hold the government accountable.  Also in com...

evolution

                  The artic le which I have just read was written by Nicholas R. Longrich and is an answer for reader’s question about humans future.                 The author of this text presents his speculations about our future evolution. I can fully agree that our life expectancy will expand through the time. As we invent more medications and cure more diseases we can expect to live longer. Although the assumption of people getting taller surprised me, I understand that given our rising length of life we will grow higher. The author’s speculations related not only to our physical appearance but also our intelligence and personality. The possibility of evolving to the point where we will have less psychological problems really makes me hopeful for a better future . Mental health is often forgotten in our everyday life. The vision of people being  “immune” t...

John Keats's poems of death and los youth

  Recently I read an article titled "John Keats: how his poems of death and lost youth are resonating during COVID-19" by Richard Marggraf-Turley. The text was mainly about the life and works of this artist, but a lot can be concluded from it. Keats, practically all his life, was a witness of death, mental illnesses, and suffering. He reflected it in his works. And even after 200 years, they are more current than ever. Everybody can now experience emotions about which John Keats wrote. In times of pandemic, especially people my age, are losing their youth and time to experience new things. Quarantine also isn't a stranger to us and the poet.  I think that we can agree with Keats that it is affecting us in a bad way. We, as he said in his letters, are feeling depressed. I think that the author of the article captured and translated to pandemic times poems of Keats. https://theconversation.com/john-keats-how-his-poems-of-death-and-lost-youth-are-resonating-during-covid-...
