WASHINGTON, October 12, 2016: Have you ever noticed how some people seem to be bitten by mosquitoes more than anyone else?
Apparently, some people taste better to malaria mosquitoes than others, and scientists are trying to figure out why so they can turn that information into a repellent to protect us all from malaria.
Such a repellent might be able to prevent some of the 214 million cases of malaria the World Health Organization says occurred in 2015, mostly in Africa. About 440,000 people, most of them children, died of malaria, the WHO said.

Researchers from Johns Hopkins University School of Medicine have found evidence of what attracts malaria mosquitoes to humans for a blood meal, and the smell isn’t the only thing.
Christopher Potter, an assistant professor of neuroscience, is working on the sensing ability of mosquitoes. Unlike humans who have one nose, Potter says, mosquitoes have three pairs of noses.
These include two antennae and two maxillary palps, which are fuzzy appendages below the insect’s head and are parallel to the feeding needle, Potter said. At the end of that feeding needle or proboscis, are the labella, two small regions with neurons that recognize smells and tastes.

“So this suggests that the mosquito brain might also have a region of the brain that’s dedicated to flavor, to combining smell and taste,” he said.
“And that is something they are very likely doing when they are actually landing on us and looking around for a place to bite,” he added. “They are actually smelling us and tasting us, and perhaps that means they are also flavoring us and that is part of what they are looking for when they’re trying to decide who they should bite from and where they are going to bite.”
Potter and his colleagues made this discovery about the malaria mosquito, Anopheles gambiae, by making certain neurons in the insect’s noses fluoresce, or glow green. They wanted to trace those green-glowing external sensory neurons to the brain.

The green-glowing neurons lighted up in the brain when they were exposed to complex odors. These help the mosquito distinguish human blood from that of other warm-blooded animals.
It’s the first time scientists were able to pinpoint the exact location of the senses of smell and taste in mosquitoes.
By studying the smell- and taste-detecting neurons, the finding suggests that it’s possible mosquitoes like not only the smell of humans but our flavor as well.
“The long-term goal is to identify better repellents, things that will be better, safer, cheaper and more effective that we can manufacture on a larger scale and distribute it across the world.”
Currently, the insect repellent DEET is widely used in malaria-endemic regions, but it’s not 100 percent effective, and a fair amount of the chemical needs to be applied to the skin to repel mosquitoes. (VOA)
When it comes to our day-to-day life, there are several things which help us enhance our day with every step. One such thing is music.

Listening to upbeat or happy music also reduces stress and pressure from our minds. Many people become relaxed while listening to calming music. This is why calming sounds are used during a yoga session. Classical music seems to have the same calming and soothing effect. Furthermore, classical music has much more advantages over metal or techno music, it has proven to enhance learning and improve sleep in its listeners. A study was conducted in which participants were divided in groups where one group was exposed to classical music, another to metal and last one was supervised without any music. The group exposed to classical music showed healthier sleeping pattern than the rest.

Several brands and outlets encash on different characteristics of music. Calm and soothing music is used in spas to help customer relax. It is a known fact that our heart starts beating according to the music we are listening to. So, music with faster beats will have our heart beating faster and the slow one will have calmer effect. This is why slow music channels calm. And the same fact has led to faster and upbeat music being played in food outlets. A study conducted in a farm, where people were invited to have food, where one half was exposed to slower music and for other fast-paced music was played. Not only did the group exposed to fast-music ate faster but also ate more than the group who ate in slower one. Next time you are in a food outlet or a restaurant observe the kind of music they are playing and the eating pattern.
Music can even be a facilitator of communication. We can sometimes convey our thoughts through the medium of a song. Sometimes someone’s words justify our inner feelings better than us. Or sometimes a song brings back certain memory or a place, and takes us to that certain moment. To say music is a time-machine would not be wrong. It is a dynamic blessing that can be used throughout our lives.

As more and more people are acknowledging the importance of their mental well-being, the wave of awareness the acknowledgment has brought is unprecedented. It may not have paved a clear path towards complete healing but it certainly has shown the way. The awareness is the key to heal. Healing begins only after the problem is identified. Similar to physical illness, the identification of the problem area is the first step. Even in case of a minor wound, when we go to the hospital the nurse first locates the wound. They, then, ask how we got hurt and identify the nature of the wound. Only then, they clean, put ointment and wrap it up if it needs wrapping and protection from air and dust. Sometimes, that protection is not needed. The wound heals out in the open. Same goes when it comes to healing of a mental trauma or illness. Sometimes, we confine in professionals or our loved ones, in order to let it out and process it openly. Sometimes, the trauma reduces with time. In any way, being aware and vigilant is the way to go.
Being knowledgeable about life in general, opens many channels for you. Being knowledgeable about yourself, opens gates inside you that lead to spiritual and general awareness about the concept of self. And the inner awareness is not necessarily internal, it can be seen from the outside as well. When we have positive energy from within it radiates physically as well. Have you encountered someone who’s spiritually awakened and aware? Do they stand out in the crowd? There are prominent examples of people who have made their mark in history, there is Swami Vivekanada, his awakening has revolutionised generations, one live example we can witness is The Dalai Lama.

Awareness is the first step towards the staircase of spirituality. Healing is part of that journey. In our world, we go by our lives without paying much attention to causes of our actions. Every little thing we do, we do it for a reason. We might be suffering without being aware of it. There might be certain actions which are screaming those are trauma-response and not really us. But we go by our days, without paying heed to the fact that it really is the small actions that carry weightage in our lives. When we become attentive and thoughtful with what we do, we introspect, and then act. Thoughtless actions do not bear much fruit anyway. Thoughtfulness not only benefits us personally, but makes world a better place to live in. It really is the need of the hour to introspect every little doing and if it does not fit with the idea of self, then, it is time to find the root cause of what has us where we are.
Being self-aware is crucial as a human quality as well. When we face our problems, we gain experience, that experience leads us to understand and empathise with others’ sufferings too. It is a wholesome development.

Honestly, who hasn’t watched one of the epic series of HBO– Game of Thrones?
There’s no question that when the first episode of Game of Thrones was released on April 11, 2011, the youth population of the world became exuberant. The main reasons behind this reaction was, first, the theme of the show, and second, the hidden lessons which it put forward.
Some of the valuable lessons which the Game of Thrones taught us are:
1. The pack always survives. This aptly meant that whether your pack consists of your family or your friends, you are the strongest when you are surrounded by a support system. This is what Ned Stark taught his children, to be together when “the winter comes”.
2. Never forget who you truly are. One of the most important lessons was given by Tyrion Lannister. He taught us that we should never forget who we really are. This means that we must not forget our bad habits and where we lack. So, once we know who we are, no one could ever use our lagging points against us.
3. Reading is necessary. Tyrion Lannister said, “A mind needs books like a sword needs a whetstone.” There is absolutely no denying that reading is not a habit now-a-days, but a necessity. If you want to be sharp and smart, then you must devote sometime to books, for they would teach you a lot!
4. Always pay your debts. Well, one of the most philosophical and learned houses if Game of Thrones is House Lannister. And so, one of the sayings of their house is, “A Lannister always pays his debts.” From here we get another life lesson that we must always pay off what we owe from people.
5. Always believe, “You know nothing.” Ygritte said this to Jon Snow in a teasing manner. But, this is actually for all those who believe that they know each and everything. Well, never believe that you know everything. Always learn from new experiences and never hesitate to take advice from others.
So, these were five most significant lessons which the series Game of Thrones offered us. In reality, we all are aware of these lessons, but we never really work upon them. But now, let’s try to understand each lesson and become the heir someday!
