Wow, Old Termite gets attacked Suicide When, Why?

Researchers from the Academy of Science of the Republic Czehch and Free University of Brussels found that termites parents choose to commit suicide if attacked.

It is known through research Neocapriterme taracua termite species in French Guiana. The research team found that some individual termites have blue spots as well as his body exploded when it is held.

Allegations of suicidal behavior demonstrated by experiment that has termites contracting spots speckled with blue and not the other termites.

The results show the truth of suicidal behavior. Termites with blue spots will blow themselves when there is a strike. Meanwhile, termites are not able to commit suicide spots as well, but tend to be reluctant to do so.

Analysis by microscopy showed that the crystal blue spots in a bag which is located near the salivary glands of termites. When the bag exploded as termites who committed suicide, crystal, saliva and haemolymph mixed, produce toxins that are deadly to termites or other small insects.

Observations also showed that the termites that have the spots are old termite, while the young termites completely white.

Yves Roisin, an evolutionary biologist from the Free University told the New York Times said: "When young, they are entirely white. When age, mandibulanya 'sag', so effectively no longer to eat, but they developed crystals to defend itself. "

Spots and the development of suicidal behavior is a form of adaptation termites. This adaptation was developed by the worker termites.

"To ensure that they are still useful in the colony, taking the old termite defensive role," said Robert Hanus, researchers from the Academy of Science of the Czech Republic, as quoted by New Scientist.

Blasting away and the weapons to defend itself has actually been found in many groups of insects such as termites. However, chemical weapons such as the new taracua Neocapriterme termites were first discovered.

Explosion of the species themselves, Hanus said, is "One of the amazing explosion were found."

Found Trash Trash Can Catch

You've seen the scene in the film, in which an author fails to dispose of his writings that his body backward, but never go into the trash?

It will be the past, because someone has managed to create bins which will capture the waste that is thrown like that.

The man from the country Sakura, Japan and has a code name "FRP" decided to create her own future trash because it was inspired from a commercial advertisement.

These bins are able to read and "catch" garbage that was thrown before reaching the ground surface. It looks like a science fiction movie, but according to its inventor, who needed just a trash can on wheels mounted underneath the circuit board, a camera belonging Xbox360 Kinect to monitor the room, and a program to read the direction of the trash that was thrown.

Video uploaded by "FRP" on the site YouTube, shows the trash functioning properly capture all the objects that were thrown in any direction.

He's still going to develop this technology further because, according to a report RocketNews24, pointing at him not as accurate as the system is expected by the inventor.

After that all can be overcome, "FRP" will commercialize his work on the wider community, especially in people who are lazy to walk to the trash.

Why Birds Parrots Can Imitate Human Voice?

Have you ever wondered why parrots can imitate human speech well? Well, want to know, parrots can talk like a human being as a parrot uses its tongue to produce a sound like the vowel letters, as well as us, humans.

In humans, the sound generated from the larynx (larynx) and can be changed according to the movement of the tongue in the mouth. Things like this that help us to pronounce vowels and consonants even though the letter was complicated.

Up to now, not a few researchers believe, parrots as well as the other birds, produce and varying the sound by using the larynx and syrinx without using his tongue at all. Apparently, parrots tongue moves forward and backward when talking.

It is then intriguing Gabriel Beckers and colleagues from the University of Leiden, the Netherlands, interested to observe whether this movement was instrumental in the smart parrots imitate human speech.

The researchers tried to do research on a number of parrots. Syrinx of birds and then replaced a very small electronic speaker. When the amplifier out the sound, a hook to move the bird's tongue.

The researchers found, the movement of the tongue is less than a millimeter will make a big difference related to the quality of vocal sound is expelled parrots.

Continue perbedaannyaya how big? The difference is, says Beckers, greater than the difference between the letter 'a' and 'o' the man said.

Thus, according to Beckers, parrots ability to play his tongue utter vowel letters may be a copycat bird driven talent.

Effect of fasting Mysterious Brain

When we fast, of course, eating patterns have changed compared to a typical day outside the month of Ramadan. As a result, many changes occur in the body. Starting from the digestive system to otak.Karena during fasting there is the release of hormones that interfere with the way the body changes food into energy, then the resulting number of mitochondria in neurons of the brain (which tells hunger signals) will increase.

Fasting brain Mysterious Effect On Brain

Unique, fasting was giving some mysterious benefit to the brain. A study by the National Institute on Aging indicates that the reduction in the time interval foods may protect the brain from diseases such as Alzheimer's and Parkinson's.

The researcher explained that dietary restriction can stimulate the production of new neurons from stem cells (neurogenesis) and can enhance synaptic plasticity, which can increase the brain's ability to resist aging and restore injured advanced functions.

Therefore, increasing the time interval between meals can be beneficial for the brain, even when the amount of food increased and there was no decrease in caloric intake.

On the other hand, low blood sugar levels during fasting can lock the brain into a deep sleep stages. Fasting improves the quality and intensify the depth of sleep. This will be good for body and brain repair processes occur during sleep.

This is why two hours of sleep during the month of Ramadan is more than satisfying and refreshing sleep for your brain biasanya.Mau remain well-maintained? Yes, continue fasting until the end of Ramadan.

Horned Snakes Found in Tanzania

New species of horned viper and found in the area of ​​Tanzania. Type of snake was named Atheris matildae found Tim Davenport, scientists from the Wildlife Conservation Society (WCS) and the team through the expedition to the region.

Atheris matildae known to be close relatives of Atheris cerathopora, horned serpents and venomous species which are found in the woods. Scientists predict that the horned snake Matilda separated into a new species from 2.2 million years ago.

One of the horned snake horned Matilda with jungle snake is bigger in size, about 64.3 cm. Another difference is the different colors, yellow and black alloys, as well as the typical pattern of scales on the head.

Davenport said Atheris matildae habitat is very limited, only an area of ​​100 sq km and has been degraded. Davenport said that the species should be included in the category of "Endangered" in the red list of the International Union for Conservation of Nature (IUCN).

Found in Tanzania, the specific location of the discovery of this snake species remain confidential. Is assembled with the magnitude of the threat to the survival of the species. Snakes with eksotismenya often hunted for their skin or used as pets.

"Global wildlife trade is enormous, and the significance of the illegal trade in amphibians and reptiles are wild, to pets. Snakes are very popular and growing interest in new types of snakes are high," said Davenport just as quoted by Mongabay on Thursday (15/12 / 2011).

To maintain the continuity of the horned snake species Matilda, now scientists are taking 4 males, 5 females and 2 pups from Atheris matildae to bred. The effort is expected to be guaranteed the existence of horned snakes Matilda.

"We plan to provide the first dozen of this snake for free in order to give supply to the captive market of this new species. Aim to prevent the collection of wild catches, lower prices and encourage responsible breeding by experts from various countries who most want it," said Davenport .
