We're letting the Nintendo fans that Masahiro Sakurai, the brains behind titled like Super Smash Bros. Brawl, will be holding a talk in Japan later this month. Wondering just what sort of topics Sakurai-san's got brewing? Details are available in the full article.

It is common knowledge that mice normally cower at even the scent of cats. This concept might be changing soon since some scientists from the Tokyo University have discovered a way to genetically engineer mice which show no fear towards felines.

These experiments may not seem like much at the current stage, but actually have quite a big impact on what we understand about the emotion called fear. Click on the "read more "link below for more details.

If you enjoy your sushi fresh, you won't have to worry about it running out any time soon. Scientists from the Tokyo University of Marine Science and Technology have been studying for a way to preserve the dwindling fish population due to overfishing and may have found just the solution to stem the tide.

By injecting specialized trout sex cells into salmon embryos, scientists were able to produce male salmon that can inject trout milt (semen), as well as female salmon that can bear trout eggs. One out of four salmon offsprings have been found to have coloration and traits similar to the target trout species they have been trying to preserve. Furthermore, these trout offspring were able to produce more of their corresponding species through normal fertilization means.

Other endangered fish species have also been targetted, such as the brown trout and the Japanese char. However, their real goal is the repopulation of Japan's favorite fish: the bluefin tuna. There have always been difficulties trying to breed such a species in captivity, but with this method Goro Yoshizaki, a marine bioscientist, explains the benefits that such a method will have on the fishing industry: "If we can produce surrogate mackerel, whose body size is 500 to 1,000 grams—nearly 1,000 times smaller than tuna—we can save space, cost and labor to produce a tuna baby."

For women who have a "slight problem" in the bust department, some scientists may have a more natural looking solution up their sleeves. Scientists in Japan claim to be able to increase the size of a woman's breast using fat and stem cells. According to them, the technique would be using fat from the stomach or thigh, this will then be enriched with stem cells, then would finally be injected.

Kotaru Yoshimura, a surgeon at the Tokyo University medical school said that more than 40 patients had been treated and that this technique aims to give the women with a more natural looking alternative compared to breast implants.

The doctor also said that this method can increase cupsize by two sizes and that there have been no serious complications in the patients. Yoshimura also added that breast enlargement using fat and stem cells did not create a lumpy effect.

For now, the Cellport Clinic Yokohama in Japan is the only medical institution offering this kind of treatment. Consultants and other experts, however, have expressed their doubts about this procedure. Some are saying that this is more of an optimistic view of a theoretical approach, but there are others who are open to exploring this procedure.
