Octopuses may be many mariners' nightmares, but new research has added
growing evidence that they may dream while asleep.
Octopuses
to undergo two different stages of sleep: 'quiet sleep' and 'active sleep', the latter of which involves twitching body parts and rapid changes in the texture and patterning of the skin.
Researchers
the Japanese Institute of Science claim - in addition to confirming that octopuses do indeed sleep during this active stage - they have also discovered that this stage shares many characteristics with REM sleep in humans.
Prof. Tom Roody, the study's lead author, said the team's findings were not proof that octopuses dream. "Perhaps we
already associate certain skin patterns during wakefulness to particular situations: hunting, social displays, threat displays, and camouflage to different sorts of environments. These patterns reappear during active sleep," he said. "So, if we are looking at something like dreaming,
I repeat, this is a possibility we do not prove in this study, they would resemble a pseudo random walk over waking experiences.
The age of digital media has seen the appearance of new opportunities for professional success, which defy traditional principles and requirements of 'making it big'.
These individuals, who have gathered a significant following on social media platforms, hold a unique position as trendsetters and opinion leaders. The phenomenon has completely revolutionised the notion of influence, transforming the way people grasp information, make purchasing decisions and engage with brands.
So, what does it take and how is it done? Whereas some influencers can attribute their popularity to sophisticated education and exceptional expertise, others monetise their charisma or a sense of humour that enables them to capture and entertain audiences. They often focus on niches - specific segments within a broader market or field.
. By creating compelling content related to corresponding products or services, they inspire, inform and entertain millions of people worldwide.
The expansion of the influencer marketing phenomenon can undoubtedly be linked to the power of social media.
. Unlike in traditional advertising, a more personal and authentic approach to promotion is achieved. There is a sense of confidence in the person that one feels towards a trusted peer, making their recommendations and endorsements highly influential.

For the vast majority of people in my class, one of the most common barriers to conversing in a new language is the fear of a teacher's reaction. Being a communicative type of learner, I ignore the pattern and the structure of a language, but I will use it regardless of the risk of using some awkward or incorrect word. Once, I needed to replace a broken item in a store in Spain. I had to use Spanish instead of my native English, although my speaking skills were at an elementary level at that time. As usual, I thanked the shop assistant for correcting my pronunciation.

At the very beginning, my friend advised me to pick out 50 French words and commit them to memory in various contexts. I have also compiled a script of useful phrases I have picked up while doing the shopping or reading notices in public places. Then, in the city where I am currently living there is a regular language-immersion meet-up group with a tutor, which joins people practising the language together in a carefree way, etc. This has given me the opportunity to absorb it as often as possible in many ways. I am aware that in order to master it, I will have to focus on structures and tenses in the future.

My teachers proposed reading comics while commuting since they use fairly simple language and my brain can easily memorise new language structures via the pictures. Now, I have moved on to adapted readers and if I don't understand a word, I can always consult the dictionary. I was advised to write the translation on the page margin. Although the first pages are fully packed, I can say I understand more with each chapter and need to look up fewer words. I also highlight the structures I think might be useful later.

Today scientists know processed foods can be dangerous. In some countries food and beverage makers must attach a Nutrition Fact label to their products. It lists daily recommendations and all the ingredients, including trans fats if they're used. In 2007 New York City banned trans fats from all restaurants, and to recent studies this has prevented hundreds of heart attacks and strokes. Even fast food chains such as McDonalds are now forced to change their recipes as people become more health-conscious. European food manufacturers have started using labels that show
We all need some fat in diet. There are three different types of fats: saturated fats, unsaturated fats and trans fats. Doctors recommend that we get most of our fatty calories from unsaturated fats. Neither butter nor margarine fit this category, though other spreads like peanut butter . Reading the label is a good way of avoiding dangerous ingredients way is to avoid eating out, especially in fast food restaurants. Also, try to buy your food in the fresh-food section. You might not think this is important, but the choices you now will affect you for the rest of your life. The healthier your diet is now, the longer and healthier your life will be.
