Diamagnetica levitation

While researching a cool frog earlier I sawr on teh wikipedia that it is possible to make frogs levitate using a magnetic field.

And there's a youtube showing it lulz. Apparently you can do it to things with high water content and even live animals like grasshoppers or frogs? I'm not sure, hard to make heads or tails of the wiki article on it.




Enjoy.

Bedbugs



I've never had them. I thought I did but it turned out to be a hungry little spider that was biting me in the night.

According to Wikipedia: The common bedbug (Cimex lectularius) is the best adapted to human environments. It is found in temperate climates throughout the world and feasts on the flesh of humans. Other species include Cimex hemipterus, found in tropical regions (as well as Florida), which also infests poultry and bats, and Leptocimex boueti, found in the tropics of West Africa and South America, which infests bats and humans. Cimex pilosellus and Cimex pipistrella primarily infest bats, while Haematosiphon inodora, a species of North America, primarily infests poultry.

The eeew news...
Reproduction: All bedbugs mate via a process termed traumatic insemination. Instead of inserting their genitalia into the female's reproductive tract as is typical in copulation, males instead pierce females with hypodermic genitalia and ejaculate into the body cavity. This form of mating is thought to have evolved as a way for males to overcome female mating resistance. Traumatic insemination imposes a cost on females in terms of physical damage and increased risk of infection. To reduce these costs females have evolved internal and external "paragenital" structures.

Feeding Habits: Bedbugs are generally active only at dawn, with a peak attack period about an hour before sunrise. They may attempt to feed at other times, however, given the opportunity, and have been observed to feed at any time of the day. Attracted by warmth and the presence of carbon dioxide, the bug pierces the skin of its host with two hollow tubes. With one tube it injects its saliva, which contains anticoagulants and anesthetics, while with the other it withdraws the blood of its host. After feeding for about five minutes, the bug returns to its hiding place. The bites cannot usually be felt until some minutes or hours later, as a dermatological reaction to the injected agents, and the first inclination of a bite usually comes from the desire to scratch the bite site.

The bad news...
Bedbugs may be erroneously associated with filth in the mistaken notion that this attracts them. However, severe infestations are often associated with poor housekeeping and clutter. Bedbugs are attracted by exhaled carbon dioxide and body heat, not by dirt, and they feed on blood, not waste. In short, the cleanliness of their environments has effect on the control of bedbugs but, unlike cockroaches, does not have a direct effect on bedbugs as they feed on their hosts and not on waste. Good housekeeping in association with proper preparation and mechanical removal by vacuuming will certainly assist in control.

The good news...
Bed bugs seem to possess all of the necessary prerequisites for being capable of passing diseases from one host to another, but there have been no known cases of bed bugs passing disease from host to host. There are at least twenty-seven known pathogens (some estimates are as high as forty-one) that are capable of living inside a bed bug or on its mouthparts. Extensive testing has been done in laboratory settings that also conclude that bed bugs are unlikely to pass disease from one person to another. Therefore bedbugs are less dangerous than some more common insects such as the flea. However, transmission of trypanosomiasis (Chagas disease) or hepatitis B might be possible in appropriate settings.

Glass Frog

Per wikipedia (slightly edited):

"Glass frog is the common/popular name for the frogs of the amphibian family Centrolenidae (order Anura). While the general background coloration of most glassfrogs is primarily lime green; the ventral skin of some members of this family is transparent (species of the genus Hyalinobatrachium). The internal viscera, including the heart, liver, and digestive tract can be seen due to the translucency of the ventral skin. "


OK, who wants to see what I ate for lunch, while I am still digesting it?

I am this caterpillar

Do you feel that somehow an irrational attachment has been implanted in you by a malign parasitic entity that will one day cause your destruction, but you are helpless to resist its control over your brain? Well, then perhaps you are a caterpillar.



A Brazilian wasp has evolved a very peculiar mind-control power in order to reproduce: It induces love in a species of caterpillar. The wasp lays its eggs in a baby caterpillar, which grows normally as the eggs grow inside it. Eventually, larvae burst out of the caterpillar's body, and that's when things get weird. The caterpillar covers the larvae with silk, and will protect them quite violently until they are full-grown wasps (you can see that in this picture). In fact, the caterpillar refuses to eat or leave until the wasps hatch.

A group of researchers observing this Brazilian insect drama in the wild say it's the first time they've been able to prove scientifically that parasites essentially mind-control their hosts to ensure the parasites' survival.

Inside the caterpillar host, a cruel drama takes place: the eggs of the parasitoid hatch and the larvae feed on the body fluids of the host. The caterpillar continues feeding, moving and growing like its unparasitized brothers and sisters. When the parasitoid larvae are full-grown, they emerge together through the host's skin, and start pupating nearby. Unlike many other combinations of host and parasitoid, the host remains alive but displays spectacular changes in its behaviour: it stops feeding and remains close to the parasitoid pupae. Moreover, it defends the parasitoid pupae against approaching predators with violent head-swings.

The caterpillar dies soon after the adult parasitoids emerge from their pupae, so there can be no benefit whatsoever for the caterpillars . . . The research team found that, in the field, parasitoid pupae which were guarded by caterpillars suffered half as much predation as those which had no bodyguard. Hence, the behavioural changes of the host result in increased survival of the parasitoids.

Yup, this behavior sounds all too familiar. What wasp has laid its eggs in my brain?

wow!

I know there are most likely  alot of these, but i found this pic and couldnt believe it

"

On August 11th, a very unusual child was born. The baby-boy was named Nikita. Another body was growing on the baby's stomach—it had little legs, hands, genitals, but no head. Nikita was urgently taken to the regional center, where doctors removed excessive body parts.

Yury Kozlov, chief doctor of the hospital's surgery department talks about the unique operation.

Nikita

"Mass media outlets in Irkutsk were writing about the birth of Siamese twins, which was incorrect. There are a lot of Siamese twins in the world. The word "Siamese" originates from "Siam" - a territory in India, where a lot of such babies are born because of closely-related marriages. In fact, two twins simply grow together symmetrically. However, there was no symmetry with Nikita, the bifurcation was incomplete. There was a healthy child (specialists call it the "host-child") and a "parasite child" growing from the stomach. The parasite child did not have a head, it had no lungs and no heart, although it had a kidney, the urinary bladder, the urethra and the intestines. The parasite child was living with the host child's help."

Modern medicine knows only twelve incidents, when a baby was born with a parasite child, growing in the stomach. There was an incident, when another baby was growing inside the abdominal cavity. The recent operation in the Siberian city of Irkutsk was the first example of bifurcation, when the "parasite" was growing on the baby's stomach. Dr. Kozlov performed a similar operation about four years ago, but the parasite baby was growing on the back.

"If Nikita were absolutely healthy, it would be possible to delay the operation for up to one or three years. It would only be a cosmetic problem. Usually, such operations are performed when a child turns 12 months, because this is the age, when a baby starts walking, and the parasite child may prevent the normal development of the host child. We had to operate Nikita urgently, because he had a congenital heart disorder. The parasite child worsened the blood circulation, and Nikita's heart could not cope with such hard work. It was hard for the boy to feed two bodies. In addition, Nikita will have to have a heart operation at the age of three months. Doctors would not venture to perform an operation with the parasite baby," Dr. Kozlov said.

Nikita became his mother's second child, born to her second marriage. Her daughter is a normal, healthy child. Nikita will stay at the hospital until he is a month old. Doctors will be observing him in the future too. Nikita's heart disease is quiet now, but this situation usually lasts for three months. At the age of three months, a crisis may happen, when a very serious heart operation will be necessary. Such an operation may be performed in Novosibirsk, in Moscow or St. Petersburg."

Bot Fly

I went to Belize last year and upon my arrival home the mosquito bite on my head would not go away. In fact it grew. After 3 weeks and a lot of pain coming from this bite I asked my husband to take a look. We didn't have heath insurance at the time. My husband diagnosed it as a bot fly, and he knew how to remove it.
So he did. It took over 2 hours and was the most painful thing I have ever experienced in my life.
Unfortunately my husband did not take photographs or video of the ordeal, but I found a youtube video of someone who did.

Enjoy! And remember I had one of these things growing in my HEAD!!!
