Bee parasite’s genome sequenced

"Scientists from the U.S. Department of Agriculture have sequenced the genome of a bee parasite suspected of contributing to colony collapse disorder -- the mysterious disease that has been killing large numbers of honeybees since 2006. The study appears in the journal in PLoS Pathogens.
The parasite, Nosema ceranae, causes a fungal disease, infecting honeybees first through their digestive tract. It then spreads to other tissue and organs in the bees, including their brains and salivary glands.
Understanding the genetic makeup of the parasite could allow researchers to trace its lineage, determine if there are different variants of the parasite, understand how it infects and causes disease in honeybees. Ultimately, they be be able to discover its role is in colony collapse disorder.
“The whole group of parasites it belongs to has mysterious effects on insects, and we don’t know much about their biology,” says Jay Evans, an entomologist with the Agricultural Research Service.
The Nosema ceranae parasite was first identified in Asia, but in recent years has spread throughout the world and is now the main bee parasite in North America and Europe. It is a suspected contributor to colony collapse disorder because it has been found in the bee carcasses of collapsed hives and its spread coincided with the spread of the disorder. However, Nosema ceranae is not always associated with disease. In Maryland, for example, the parasite exists, but there have not been any cases of colony collapse disorder."

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.
