Giving Birth to a Patagonian Red Octopus

We all are known about Octopus, which have 8 legs and no bone. It has a special character that “It can change his color any time”. Generally an Octopus can be found in the deepest position of sea. It’s so much dangerous. If it caught any fish, it is impossible becoming free for the fish. Their eggs much be easier—being naturally contained and all. Not always, it turns out.


A team of researchers in Chile have been on a quest to grow a local octopus species in captivity after it was over fished in the wild. The results were published this year in Aquaculture.
Patagonian Red Octopus is so small. It is one meter long. It is slow glower. Its eggs are also so sensitive. The eggs alone take five months of careful incubation and tending before hatching. And no one was sure the best way to keep these sensitive octo eggs alive.
A team of researchers from Chile and Mexico captured 16 females and 12 males and take them in lab. The researchers put a Octopus in a tank. They let the Octopus to mate and then left the females alone again to lay and tend to their eggs—hoping to glean a few clues about embryonic development patterns and tending tips.
2095 is an average number of egg laid by an female Octopus. At first the egg is 10 millimeters. But in time of hatch it reaches in 14 millimeters. The eggs get many kind of nutrition during hatch. 40% to 100% eggs are lost by the female Octopus. She was only able to hatched 15% eggs only.
Assessing the contents of the egg yolk sac during the embryo development, they found that the octopuses used up just about all of the nutrients before hatching. In particular, unsaturated fatty acids seemed important to regulate membranes in the cold water environment. And, like developing human babies, the octopuses also had “a high demand for DHA to form a well-developed nervous system that ensures predatory skills of newly hatched individuals,” the researchers noted in their paper. Of course, in the wild, almost all of the baby octopuses that did hatch would get eaten up by predators—or would fail to feed themselves enough to grow to maturity.


But the researchers are hoping to learn more from the octo moms to figure out how to keep the hatchlings alive and healthy, at least in captivity.

Breast Cancer!!

Introduction: Science's special section on breast cancer takes a look at the state of research and treatment 20 years after the isolation of the BRCA1 gene


In the whole world breast cancer in most scared able for women.  Women are using tied cloths for a long time or use perfume very much becomes attacked by this virus. A prostitute also can attack. In the ranking the women of Europe, America, Africa and Asia is in the danger line.
The treatment of breast cancer is so complicated. Many women had to die for that although they take treatment. If the treatment can start in initial moment it can finally removed. On the other hand the treatment is so expensive.
When deciding what treatment is best for you, your doctors will consider:
The stage and grade of your cancer (how big it is and how far it has spread)
Your general health
Whether you have been through the menopause
You can discuss your treatment with your care team at any time and ask any questions.
The main treatments for breast cancer are:
Surgery
Radiotherapy
Chemotherapy
Hormone therapy
Biological therapy (targeted therapy)
You may have one of these treatments or a combination. The type of treatment or the combination of treatments will depend on how the cancer was diagnosed and the stage it is at. Breast cancer diagnosed at screening may be at an early stage, but breast cancer diagnosed when you have symptoms may be at a later stage and require a different treatment. Your healthcare team will discuss with you which treatments are most suitable



In our face we show twenty emotions!!

Yeah that’s true.
“I thought it was very odd to have only one positive emotion,” says cognitive scientist Aleix Martinez of Ohio State University in Columbus.

Like him every scientist thought that people could convey only happiness, surprise, sadness, anger, fear and disgust.
He and colleagues came up with 16 combined ones, such as “happily disgusted” and “happily surprised.” Then the researchers asked volunteers to imagine situations that would provoke these emotions, such as listening to a gross joke, or getting unexpected good news.
The team compared pictures of the volunteers making different faces and analyzed every eyebrow wrinkle, mouth stretch and tightened chin, “what we found was beyond belief,” Martinez says. For each compound emotion everyone used the same facial muscles. The team reports on March 31 in the Proceedings of the National Academy of Sciences.

This research may be help computer engineer to develop face recognized software and help scientists better understand emotion-perception disorders such as schizophrenia.
