chicks are hopeless
ina samjhan de baad vi shakal hi pasand aundi aa kudiya nu.
no wonder kudia dhokha khandia :wait:
Why do you always feel the need to be so condescending towards females? I've noticed this on several occasions. Bad experiences? Or just plain out narrow mindedness as Elle said?

it doesn't matter, as long as they plan on staying married, however would prefer from our own culture. It would be easy to get along with the rest of the folks.

sounds intersting....
but am still skeptic about the generalization of the findings to humans
but atleast they'll come out with something which will reveal the mystery of host and the virus interaction
at least it's a start (trial and error process). Seems pretty interesting how their RNA can simply turn off certain genes.

Parasites are sly, using the cleverest of ploys to stay alive while destroying almost everything in their tracks. Parasites have no mercy. Some devour the insides of their hosts. Another replaces the victim's tongue with its own body. Here are some of the goriest highlights of the moocher world.
10. Sexually Transmitted Dog Cancer
Dogs have a form of sexually transmitted cancer that for 200 to 2,500 years has apparently spread via contagious tumor cells that escaped from their original body. These cells now travel around the world as parasites, draining nutrients from their hosts. This affliction, known as canine transmissible venereal tumor or CTVT, is spread through sex and licking, biting and sniffing cancerous areas. The tumors usually regress three to nine months after their appearance, leaving the dogs immune to reinfection, although providing enough time for dogs to pass the disease on. They represent the oldest cancers known to science thus far.
9.Tyrannosaur-starving Parasite
The famous dinosaur known as Sue -- the largest, most complete and best-preserved T. rex specimen ever found -- might have been killed by Trichomonas gallinae, a protozoan that afflicts birds even today. The remains of Sue, a star attraction of the Field Museum in Chicago, possess holes in her jaw that some believed were battle scars, the result of bloody combat with another dinosaur, possibly another T. rex. Now researchers suggest these scars did not result from a clash of titans, but rather from the protozoan infecting Sue's throat and mouth. Some birds, such as pigeons, commonly host the parasite yet suffer few ill effects. But in birds of prey, such as falcons and hawks, the germ causes a pattern of serious lesions in the lower beak that closely matches the holes in the jaws of Sue and occurs in the same anatomical location. The infestation might have been so severe that the 42-foot-long, 7-ton dinosaur starved to death.
8.Web-manipulating Wasps
Although parasites harm their hosts, they don't usually kill them, if only to keep themselves alive. Not so with parasitoids, which ultimately destroy and often consume their hosts. Parasitoid wasps, which inspired the monster in the movie "Alien," lay their eggs inside their victims, with the offspring eventually devouring their way out. A number of the species control their host's minds in extraordinary ways -- the larvae of the wasp Hymenoepimecis argyraphaga, which infests the spider Plesiometa argyra, makes their victims spin unusual webs especially well-suited for supporting their cocoons.
7. Male-killing Bacteria
The genus of bacteria known as Wolbachia infests a whopping 70 percent of the world's invertebrates, and has evolved devious strategies to keep spreading. In female hosts, the germ can hitch a ride to the next generation aboard the mother's eggs, and since males are essentially useless for the bacteria's survival, the parasite often eliminates them to increase the rate of females born, by either killing male embryos outright or turning them into females. Incredibly, the bacteria have even found a way to sneak their entire genomes into the cells of fruit fly hosts.
6. Ant-deceiving Butterfly
Just like cuckoo birds, the Japanese lycaenid butterfly Niphanda fusca lays its eggs in the nests of other species, in this case the carpenter ant Camponotus japonicus. The caterpillars that hatch from these eggs then dupe the ants into adopting them by mimicking the odor of the high-ranking male ant caste. Such a chemical disguise explains why these "social parasite" moochers are enthusiastically fed by their hapless hosts in preference to the ants' own brood.
5. Eye-infesting Worm
The worm Loa loa, which dwells in rainforests and swamps of West Africa, infects people through the bite of a deerfly or a mango fly. The worms wander under the skin of their victims at all times of day, feeding on fluids in human tissues. The worms live in the bloodstream when the sun is out and people are most likely to get bitten by flies that can, in turn, spread the worms to other unwitting martyrs; they retreat into the lungs at night. They occasionally cross into the eyes, where they can be quite painful.
4. Feminizing Barnacles
The females of the parasitic barnacles known as Sacculina carcini invade crabs, sprouting root-like tendrils that reach throughout their victim's body, even coiling around its eyestalks. Living off nutrients dissolved in the crab's blood, this parasite grows into a bulge on the host's underside where it can house any offspring. Infected female crabs nurture this knob as they would the fertilized eggs they normally keep at that spot; parasitized male crabs grow abdomens as wide as the girth of a female, wide enough to accommodate the barnacle's knob, and grooms the parasite just as infected female crabs would their own family.
3. Head-bursting Fungus
In a bizarre death sentence, the fungus Ophiocordyceps unilateralis turns carpenter ants into the walking dead. The fungus prefers the undersides of leaves of plants growing on the forest floor. That's where temperature, humidity and sunlight are ideal for the fungus to grow and reproduce and infect more victims. The parasite gets the insects to die hanging upside down, and then erupts a long stalk from their heads with which it sprinkle its spores to other ants. Fossil evidence recently suggested this fungus has zombified ants for millions of years.
2. Tongue-eating Crustacean
The crustacean Cymothoa exigua has the dubious and unsettling honor of being the only parasite known to replace an organ. It enters through the gills of the spotted rose snapper, attaching to the base of the fish's tongue, where it drinks its blood. The bloodsucking causes the tongue to eventually wither away, at which point the crustacean attaches itself to the tongue stub, acting as the fish's tongue from then on.
1. Mind-controlling Protozoan
A mind-controlling parasite might sound like the stuff of science fiction, but the protozoan known as Toxoplasma gondii is all too real. To hop from rats to cats, its primary host, Toxoplasma makes the rodents become attracted to cat pee, increasing the chance they'll become cat food. Disturbingly, the germ also infects more than half the world's human population, and could make people more prone to some forms of neuroticism, shaping entire cultures, researchers have suggested.
That's not the only parasite that make its hosts love what they should loathe. The worm Pomphorhynchus laevis hops from crustaceans to predatory fish by making their hapless victims drawn to fishy scents.

The worms in microbiologist Marie-Anne Felix's lab are feeling a little under the weather. It seems they've picked up a stomach virus. The virus is actually the first ever found to infect the nematode C. elegans, a carefully studied worm that scientists use for basic research.
Studying the sick worms will teach researchers how viruses interact with their hosts — which, in some cases like HIV and influenza, are humans.
While viruses — unique forms of life that cannot grow or reproduce outside a host cell — infect everything from bacteria to plants and mammals, researchers had been unable to find any that infected this nematode.
"Prior efforts didn't look with the right tools and didn't look in the right place," study researcher David Wang, a microbiologist at Washington University School of Medicine in St. Louis, told LiveScience. "We have a combination of expertise." Felix is a worm specialist, and Wang, a virus hunter.
C. elegans is one of the most studied organisms on the planet (and even off the planet). Researchers have sequenced its genome and documented the development of each of its cells. They can turn on and off most of its genes at will, through a process called RNA interference (or RNAi).
This interference process also happens naturally in many organisms. Some, like plants and fruit flies, use RNAi to fight off viruses. In these organisms, the RNAi can turn off the genes of the invading virus, stopping it in its tracks.
Studying how the newly discovered virus interacts with such an essential RNAi model system as the nematode could shed light on how RNAi is used in humans, Wang said. "This has the potential to teach us something fundamentally new about how organisms respond to viral infections," he said. "There might be parallel pathways in humans."
.Felix, of the Jacques Monod institute in Paris, found the virus in sick worms she had collected from rotting apples and grapes. She could tell the worms were sick, but they didn't get better after a course of antibiotics. She was able to infect other C. elegans worms with a mix from mashed-up infected worms that had been filtered to remove anything larger than a virus (about 20 nanometers, or the width of a very thin human hair). Even after being filtered, the liquid could make worms sick.
Felix asked Wang to try to identify the virus that made it through the filter. He found that it was a type called Nodaviridae, which infect insects and fish, though it is only about 40 percent similar to previously known nodaviruses. The virus, and its closely related cousin the team discovered was infecting the nematode C. briggsae, might even be a completely new family, Wang said.
The virus easily infects the wild worms, though once they did they only caused changes in the gut cells. The worms still lived long and seemingly happy lives, although with fewer offspring.
The commonly used lab strain of C. elegans was less susceptible to the virus, but another strain, which is RNAi-deficient, was more susceptible.
Because of this, it seems likely the worms use RNAi in the same anti-viral way that Drosophila and plants do. Because the C. elegans is such a well-defined model system, researchers can see which genes make the worm more or less susceptible to its viral invaders.
"It adds an approach to the repertoire of tools that researchers can use to understand virus-host interactions" in humans, Wang said.
Dennis Kim, a researcher who studies bacterial infections of C. elegans at MIT, noted in an e-mail to LiveScience that the system "will provide insights into the ecology and evolution of host-virus interactions." Kim was not involved in the current study.
Wang agreed, but noted that studying host-virus interactions in C. elegans "has the limitations of a model organism, in that we might find things that are only applicable to the model." Still, he said, most of the fundamental processes of viral infection should be similar in humans.
The paper was published today (Jan. 25) in the journal PLoS Biology.
