The Tadpole shrimp Triops Cancriformis is found in the Caerlaverock nature reserve in Dumfriesshire at Scotland. This species is considered as to be the Oldest species on the earth.
Triopes is one of the genus of small Crustaceans. It is the freshwater animals and sometimes they are kept as pets. Triopes are also known as the "Living Fossils", It is because one of the species, which is triops cancriformis, changed very littile since the Triassic. Approximately it is arround 220 Million Years ago. Triops gives the eggs, which comes in the state of extended diapause, when its dry. They then waits for many years for the water, At that time they hatches and starts their life cycle again. Triopes are called so because of they having three eyes.

0 After Oil Spill at Maxico, Now in Dalian, China -Pictures 13+

Five days ago, in the northeastern port city of Dalian, China, two oil pipelines exploded, sending flames hundreds of feet into the air and burning for over 15 hours, destroying several structures - the cause of the explosion is under investigation. The damaged pipes released thousands of gallons of oil, which flowed into the nearby harbor and the Yellow Sea. The total amount of oil spilled is still not clear, though China Central Television earlier reported an estimate of 1,500 (400,000 gallons), as compared to the estimated 94 - 184 million gallons in the BP oil spill off the Louisiana coast. The oil slick has now grown to at least 430 square kilometers (165 sq mi), forcing beaches and port facilities to close while government workers and local fishermen work to contain and clean up the spill.











































0 Now Genetically Modified Mosquitoes are Totally 100 perc. Resistant to Malaria Parasite

A few scientists at the Arizona University have achived the mosquitoes that are totally 100 percent resistant to the malaria parasite. They have successfully bred this kind of genetically engineered mosquitoes. And the great thing about this mosquitoes are that, they are incapable of infecting humans with malaria.

For hundreds of years, researchers from around the world are trying to alter the mosquitoes, which cannot infect the humans with malaria. infect, all those attempts were not useful because still mosquitoes are capable of transmitting the diseases causing pathogens called Plasmodium. Each year around 250 Million ppl gets infected by the malaria, and about 1 Million people gets die. There is not any effective malaria vaccines are available. A mosquito belonging to the genus Anopheles is able to act as vector. Around 25 of anopheles are significant vectors of this disease.


The previous attemps were only to the around 97 percent of destroying the malaria parasite in mosquitoes bodies, but the rest of the 3 percents were about which was itching to the scientists. Michael Riehle is the scientist, who has come up with this new study, and he has also covered thoose 3 percent and succed and altered the whole genetic material that is resistant of malaria parasite by 100 percent.

The genetic material designed by the Riehle's team, [Michael Riehle is a professor of entomology in UA's college of agriculture and life sciences and is a member of the BIO5 Institute.] that inserts itself into a mosquito's genome. Then after researchers fed malaria infested blood to the modified mosquitoes, the Plasmodium parasites didn't infect a single animal in the study. And once the anti malaria molecule is injected  into the mosquito's eggs, the next generation then carries the altered genes and passes it on to future generations. The scientist used Anopheles stephensi. This is the mosquito species that is very important malaria vector throughout the indian subcontinent.

The one major thing found in this study is that, this anti-malaria molecule shorterns the mosquito's total life span. The typical life span of a mosquito is around 2 to 3 weeks, but this gets minimize due to the anti malaria molecule. The good thing about this manner is that, The malaria parasite needs around 12 to 16 dayz to develope within a mosquito, before it get transmitted to the human body. And due to the minimize of mosquito lifespan, the chances of transmittion of parasite gets lesser. As mainly the oldest mosquitoes [Anopheles] are only responsible for the transmission of parasite.
