MessageToEagle.com - Bats are amazing creatures. They've been around for at least 65 million years, and in
that time have become one of the most abundant and widespread mammals on Earth.
The Bat Pack, a team of researchers at the Australian Animal Health Laboratory (AAHL) in Geelong, conduct a wide
range of research into bats and bat borne viruses, and their potential effects on the human population, as part of the
effort to safeguard Australia from exotic and emerging pests and diseases.
Their paper, published today in the journal Science, provides an insight into the evolution of the bat's flight,
resistance to viruses, and relatively long life.
Among the most abundant bats in North America, Mexican free–tailed bats (Tadarida brasiliensis mexicana) play an important role by devouring large numbers
of corn earworm moths, plus a similar number of other insect pests that consume corn, cotton, and other crops in Texas
and the southwestern U.S.
The Bat Pack, in collaboration with the Beijing Genome Institute, led a team that sequenced the genomes of two bat
species -- the Black Flying Fox, an Australian mega bat, and the David's Myotis, a Chinese micro bat.
Once the genomes were sequenced, they compared them to the genomes of other mammals, including humans, to find where
the similarities and differences lay.
Chris Cowled, post-doctoral fellow at AAHL says the research may eventually lead to strategies to treat, or even
prevent disease in humans.
"A deeper understanding of these evolutionary adaptations in bats may lead to better treatments for human diseases,
and may eventually enable us to predict or perhaps even prevent outbreaks of emerging bat viruses," Dr Cowled said.
"Bats are a natural reservoir for several lethal viruses, such as Hendra, Ebola and SARS, but they often don't succumb
to disease from these viruses. They're also the only mammal that can fly, and they live a long time compared to animals
similar in size."
Flying is a very energy intensive activity that also produces toxic by-products, and bats have developed some novel genes
to deal with the toxins. Some of these genes, including P53, are implicated in the development of cancer or the detection
and repair of damaged DNA.
"What we found intriguing was that some of these genes also have secondary roles in the immune system," Dr Cowled said.
"We're proposing that the evolution of flight led to a sort of spill over effect, influencing not only the immune system,
but also things like ageing and cancer."
Amazing Phenomenon Of Singing Plants
Plants are very much alive. Not only do they dislike human noise but they also posses the capacity to learn and communicate.
Perhaps even more astonishing is that plants can also make music.
Have you ever heard the incredible music of the plants? Plants can
actually sing and compose music and listening to it is truly beautiful and relaxing!
World's First High-Tech Underwater "Wonder"
This fantastic craft looks almost like an alien spacecraft, or a maritime version of Star Trek's USS Enterprise!
SeaOrbiter is a unique vessel. It is much more than the world's first vertical ship. SeaOrbiter will be constructed with the sole aim of exploring the world's oceans.
It is a scientific laboratory that will give researchers opportunity to explore the secrets of our oceans.
They Produce Water From The Air!
An Amazing Invention For Those Who Really Need It!
"How can we help someone so powerful they can create water out of thin air?" an astonished Jabin yells in Star Trek's Caretaker.
If you are a Star Trek fan you will remember how the Kazons try to aquire technology that can create water our of thin air.
This technology is no longer in the realms of science fiction. Today we can really create water out of thin air!
Unexplained Sounds Coming From The Ocean
Several very unusual sounds coming from the oceans have been recorded by scientists world-wide.
Are the sounds caused by very large life forms lurking in the unexplored darkness of Earth's deep oceans or perhaps something else?
Something is down there and experts do not know what it is...
All of these sounds have no thing in common - they remain unexplained.
