Dengue-resistant mosquitoes to be released next year




Dengue-resistant mosquitoes to be released next year

It has been revealed that next year, scientists are going to release mosquitoes which have been bred to be less able to transmit Dengue fever to Humans. These releases will occur in the countries of  Australia and Vietnam. These scientists have discovered that injecting mosquitoes with a bacteria can prevent the mosquitoes from having the capacity to live long enough to transit the Dengue fever to humans. 

"In a study published last year, Scott O'Neill of the University of Queensland in Brisbane, Australia, and colleagues found that the bacterium Wolbachia can inhibit the ability of several pathogens to infect Aedes aegypti mosquitoes, the species that spreads dengue fever."

or click on the title of this blog entry. This certainly is good news for people who live where Dengue Fever occurs.

"The mosquito can be recognized by white markings on legs and a marking in the form of a lyre on the thorax. The mosquito originated in Africa but is now found in tropical and subtropical regions throughout the world."  The photo above shows a Aedes aegypti mosquito.Aedes aegypti are attracted to chemical compounds that are emitted by mammals. These compounds include ammonia, carbon dioxide, lactic acid, and ocentol. Scientists have learned that these mosquitoes are attracted to a specific molecule in these compounds and be learning this information  they hope to better understand why this attraction occurs in this species of mosquito."

"The genome of this species of mosquito was sequenced by a consortium including scientists at the J. Craig Venter Institute and the University of Notre Dame, and published in 2007. With knowledge of the genome scientists now have been able to develop these Dengue resistant mosquitoes." (source:http://en.wikipedia.org/wiki/Aedes_aegypti ).

This scientific development certainly makes one believe if mosquitoes can be breed which are less able to tran resistant to Dengue fever, is it possible to breed mosquitoes which are resistant to other mosquito-transmitted diseases?

Thoughts worth thinking about

"Our subconscious minds have no sense of humor, play no jokes and cannot tell the difference between reality and an imagined thought or image. What we continually think about eventually will manifest in our lives."-Sidney Madwed



Laws alone can not secure freedom of expression; in order that every woman and man present their views without penalty, there must be spirit of tolerance in the entire population.- Albert Einstein Too often we underestimate the power of a touch, a smile, a kind word, a listening ear, an honest compliment, or the smallest act of caring, all of which have the potential to turn a life around. - Leo Buscaglia



A person's true wealth is the good he or she does in the world. - Mohammed



Our task must be to free ourselves... by widening our circle of compassion to embrace all living creatures and the whole of nature and its beauty. -Albert Einstein



The best way to find yourself, is to lose yourself in the service of others. - Ghandi



The unselfish effort to bring cheer to others will be the beginning of a happier life for ourselves. - Helen Keller



Aim for success, not perfection. Never give up your right to be wrong, because then you will lose the ability to learn new things and move forward with your life. Remember that fear always lurks behind perfectionism. Confronting your fears and allowing yourself the right to be human can, paradoxically, make yourself a happier and more productive person. - Dr. David M. Burns



Life is as dear to a mute creature as it is to man. Just as one wants happiness and fears pain, just as one wants to live and not die, so do other creatures. -His Holiness The Dalai Lama



Mankind's true moral test, its fundamental test (which lies deeply buried from view), consists of its attitude towards those who are at its mercy: animals. And in this respect mankind has suffered a fundamental debacle, a debacle so fundamental that all others stem from it. -



Milan Kundera, The Unbearable Lightness of Being



The worst sin towards our fellow creatures is not to hate them, but to be indifferent to them. That's the essence of inhumanity. -George Bernard Shaw

Ego's trick is to make us lose sight of our interdependence. That kind of ego-thought gives us a perfect justification to look out only for ourselves. But that is far from the truth. In reality we all depend on each other and we have to help each other. The husband has to help his wife, the wife has to help the husband, the mother has to help her children, and the children are supposed to help the parents too, whether they want to or not.-Gehlek Rinpoche Source: "The Best Buddhist Writing 2005 pg. 165

The hostile attitude of conquering nature ignores the basic interdependence of all things and events---that the world beyond the skin is actually an extension of our own bodies---and will end in destroying the very environment from which we emerge and upon which our whole life depends.
