According to a study released in the British Science journal, "Nature", a star 600 light years from Earth is devouring one of its own planets!! The star/planet , named "Wasp-12b by astronomers, was discovered last year and scientists believe it , is a "gas giant" with a mass about 40 per cent greater and a radius 79 percent larger than that of Jupiter, the biggest planet of our Solar System!!!!
WASP-12b takes only 26 hours to travel once around its star, WASP-12, located in the constellation of Auriga. Because its orbit is so fast, astronomers were able to state that WASP-12b is located very near its host star, WASP-12
Here is some additional information concerning WASP12b:
1."WASP 12b is an exoplanet. This means "it is a planet which orbits a star other than our own Sun."
2."WASP-12b orbits its host star 1/40 th of the distance at which the Earth orbits the Sun Its host star, WASP heats WASP-12b to record-breaking temperatures; the planet is being heated up to temperatures around 2250 °C!!"
3."Planets approximately the size of Jupiter orbiting close to their star in other systems are often referred to as "Hot Jupiters."
4."Scientists are at a loss to explain why WASP 1b is so large..Simulations suggest that the intense heat should keep the planet puffed up a bit — but nothing like what's observed. So the discovery team, led by Leslie Hebb (University of St. Andrews, Scotland), suspects that the planet is shrouded in energy-absorbing hazes consisting of titanium and vanadium oxides, among the few things that are solid at those temperatures. The exotic dust might be absorbing enough light and heat to puff out the planet's outer layer."
Hebb and her colleagues explore this possibility in a paper which appears in the Astrophysical Journal and which you can download by clicking on the following link:http://arxiv.org/PS_cache/arxiv/pdf/0812/0812.3240v1.pdf You need the program Adobe Acrobat Reader to view the file.
Just how common is it for a star to devour a planet?
According to Dr David Whitehouse BBC News Online science editor, who wrote the article,"Star devours planets," which you can read by clicking on the following link:
"Some researchers believe that planet swallowing may be common and may explain why so many stars have enhanced levels of metals in their surface regions. The metals may have come from engulfed planets." It is stated at the website: http://www.universetoday.com/2009/04/27/the-case-of-the-missing-planets-are-stars-eating-their-young/
"The idea that gravitational forces might pull a planet into its parent star have recently been predicted by computer models."
"When we look at the observed properties of extrasolar planets, we can see that this has already happened – some extrasolar planet have already fallen into their stars," said Rory Barnes from the University of Washington.
"The computer models can show where planets should line up in a particular star system, but direct observations show that some systems are missing planets close to the stars where models say they should be.
But because the planet is so close to the star, the two bodies begin pulling on each other with increasingly strong gravitational force, misshaping the star's surface with rising tides from its gaseous surface."

that were taken by the Cassini spacecraft in November.You can view these images by going to the following website:
Image: This image shows the south polar region of Saturn's moon Enceladus.
This image and all of the images released today by NASA were taken by the Composite Infrared Spectrometer Imaging Science Subsystem which was built into the Cassini spacecraft. The image focuses on Baghdad Sulcus, a fracture in the south polar region. Source: http://photojournal.jpl.nasa.gov/figures/PIA11697_fig1.jpg
"Enceladus is the sixth-largest moon of Saturn. It was discovered in 1789 by William Herschel.Enceladus is named after the Giant Enceladus of Greek mythology. The name Enceladus — like the names of each of the first seven satellites of Saturn to be discovered — was suggested by William Herschel's son John Herschel in his 1847 publication Results of Astronomical Observations made at the Cape of Good Hope. He chose these names because Saturn, known in Greek mythology as Cronus, was the leader of the Titans."
"Enceladus was discovered by Fredrick William Herschel on August 28, 1789, during the first use of his new 1.2 m telescope, then the largest in the world. Herschel first observed Enceladus in 1787, but in his smaller, 16.5 cm telescope, the moon was not recognized. Due to Enceladus's faint apparent magnitude (+11.7m) and its proximity to much brighter Saturn and its rings, Enceladus is difficult to observe from Earth, requiring a telescope with a mirror of 15–30 cm in diameter, depending on atmospherical conditions and light pollution."
"Enceladus orbits Saturn at a distance of 238,000 km from the planet's center and 180,000 km from its cloudtops, between the orbits of Mimas and Tethys, requiring 32.9 hours to revolve once (fast enough for its motion to be observed over a single night of observation)."
"Enceladus is a relatively small satellite, with a mean diameter of 505 km, only one-seventh the diameter of Earth's own Moon. It is small enough to fit within the length of the United Kingdom; in fact, it is barely the size of England alone." (source:http://en.wikipedia.org/wiki/Enceladus_%28moon%29)

Here is a video I found which is related to Enceladus and the Cassini mission:
This video relates to the Cassini findings of March 2006 : (source:http://saturn.jpl.nasa.gov/video/ )
DNA from ancient frozen caribou bones found in the Yukon suggests caribou herds in the area were displaced by a volcanic eruption 1,000 years ago.
Researchers from the U.S., U.K. and Canada have found that DNA from caribou remains found in the Whitehorse area older than 1,000 years doesn't match the DNA of the current population there.
The local population isn't related to herds currently living to the north, east or west, either.
This news story made me interested in discovering what the present state of caribou living in my home province of Alberta is. I found the following information:

Big cats, such as lions,tigers are among the most endangered animals on the planet, due to habitat loss and poaching by humans.Here is a beautiful photo of one of the cats as it encountered an automatic camera owned by Kashmira Kakati:
According to the blog http://bigcatnews.blogspot.com/2010/02/chinas-year-of-endangered-tiger.html,
"A century ago, more than 100,000 big cats roamed the Earth, but stocks have plummeted: scientists say there are now just 3,200. India has the largest number of wild tigers with almost 1,400.
Tiger hunting is illegal worldwide and trade in tiger parts is banned in more than 160 countries. At the website: http://animals.nationalgeographic.com/animals/photos/big-cats/#2366_600x450.jpg I found this statement:
"Lions are threatened throughout most of their African range. But nowhere is their condition as perilous as in Kenyan Maasailand, ... Lions there, which number fewer than 150, are under imminent threat of extinction from Maasai herdsmen thought to be retaliating against prides who prey on their cattle."
"Recent years have seen the extinction of two sub-species of Indonesian tiger, the Caspian Tiger from western Central Asia, a sub-species of clouded leopard from Taiwan, and the Barbary lion from the wild in North Africa. Meanwhile, populations of the Iberian lynx, Asiatic cheetah and Amur leopard have fallen so low that they would be functionally extinct without current conservation efforts. Tiger populations have declined from more than 100,000 at the turn of the century to less than 6,000 today, while cheetah number are estimated at less than 15,000. Even lion populations have dropped: from over 100,000 one hundred years ago to probably less than 40,000 today."
"Given these trends, it should come as no surprise that big cats have become the focus of conservation efforts. Not only are large predators often the most vulnerable to human pressures and the first to disappear from ecosystems, but efforts to conserve them effectively help protect thousands of other species that share their habitat."
You can read an interview of Dr. Hunter at the monabay.com website posted above.In this interview Dr. Hunter talks about what steps have to be taken to ensure that big cats do not become extinct.

Same Species, Polar Opposites: The Mystery of Identical Creatures Found in both Arctic and Antarctic Waters
Chionodraco hamatus, an Antarctic ice fish, can withstand temperatures that freeze the blood of all other fish types. Photo by H. William Detrich. (source:http://www.physorg.com/news148753307.html )
Written by Daniel Grushkin
"Two years ago, several research vessels shipped out to the North and the South poles to assemble a census of creatures living under the ice. One of the most surprising results was a discovery that 235 identical species lived on opposite sides of the world but were undocumented anywhere else. It's easy to understand how massive humpbacks can swim from Arctic to Antarctic waters, but most of the miniature worms, snails and crustaceans on the researchers' list are no bigger than grains of rice. How could tiny creatures adapted for the frigid waters travel 9,500 kilometers through warmer climes to reach the opposite pole?"

Dr. Ellen Kvestad of the Norwegian Institute of Public Health in Oslo and Akershus University Hospital says tinnitus, or the perception of sound without an external acoustic stimulus, is common, but the causes of tinnitus onset and tinnitus maintenance are far from fully understood.
Kvestad said colleagues analyzed data collected from 12,940 spouses, 27,607 parents and offspring and 11,498 siblings. All completed a questionnaire about tinnitus and underwent a hearing examination.
A subgroup of 16,186 individuals with some hearing loss and 17,785 controls were sent a second questionnaire requesting more details about tinnitus, to which a total of 28,066 responded.
About 20.9 percent of the participants reported having definite or probable symptoms of tinnitus.
The researchers found a low overall correlation that does not indicate that any prevalent type of tinnitus is largely passed down through families.
The findings are published in the Archives of Otolaryngology -- Head & Neck Surgery.

As someone who suffers from tinnitus (I believe due to the 6 rear-end car accidents I have been involved in), it sure would be nice if science could find a way to reduce this loud ringing in my ears!
According to the website:http://www.rezat.com/2009/04/hearing-loss-from-a-car-accident-loss-of-hearing-from-traumatic-impact/
"When we think of hearing loss, we typically think of a person who has listened to loud music for years, has worked in noisy industrial buildings or construction areas all of his or her working life, or the natural decline of the auditory senses with age. But hearing loss can also be due to a sudden event, such as hitting one’s head in a fall or a swift powerful blow to the side of the head such as that suffered in an automobile accident. A blow to the head that causes unconsciousness can lead to an inner-ear concussion and hearing loss. Other damages that can result in trauma to head or ear include the dislocation or fracture of the middle ear bones, fracture of the cochlea in the inner ear (the cochlea is the main sensory organ of hearing), a hole in the inner ear leading to inner ear fluid leakage, a fracture of the temporal bone fracture leading to hearing loss, and bleeding in the inner ear. Serious traumatic injuries to the ear arising from an automobile collision can cause permanent hearing loss or balance problems" (or in my case both!)
"The discovery of a large planet, which has been named BD+20 1790b,has been found to be the youngest planet ever found orbiting a star of a similar size to Earth's sun, said astronomer Maria-Cruz Galvez-Ortiz of the University of Hertfordshire.
"The planet, located 83 light years from Earth, is 35 million years old and six times the size of Jupiter, Galvez-Ortiz and her team wrote in a recent issue of the journal Astronomy & Astrophysics."There are still very few extrasolar planets that have been discovered –- only about 420," Galvez-Ortiz told The Daily Telegraph in a story reported Friday."
"BD+201790 is a very active star, and astronomers announced last year that it could possibly have a companion. An international collaboration of astronomers, led by Dr. Maria Cruz Gálvez-Ortiz and Dr. John Barnes were able to "weed out" the data to determine the planet was actually there."
"BD+20 1790b was discovered using observations made at different telescopes, including the Observatorio de Calar Alto (Almería, Spain) and the Observatorio del Roque de los Muchachos (La Palma, Spain) over the last five years. The discovery team is an international collaboration including: M.M. Hernán Obispo, E. De Castro and M. Cornide (Universidad Complutense de Madrid, Spain), M.C. Gálvez-Ortiz and J.R. Barnes, (University of Hertfordshire, U.K.), G. Anglada-Escudé (Carnegie Institution of Washington, USA) and S.R. Kane (NASA Exoplanet Institute, Caltech, USA). The discovery has just been published in the Astronomy & Astrophysics journal."
“The planet was detected by searching for very small variations in the velocity of the host star, caused by the gravitational tug of the planet as it orbits – the so-called “Doppler wobble technique,” said Gálvez-Ortiz. "Overcoming the interference caused by the activity was a major challenge for the team, but with enough data from an array of large telescopes the planet’s signature was revealed.”

Thoughts worth thinking about
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.
