Creating Clones Of Clones Of Clones: Are Dinosaurs Next?
Scientists have cloned the clone of a clone (and then some).
A team at the RIKEN Center for Developmental Biology in Kobe, Japan have successfully created a 25th generation clone, and all 580 of the cloned offspring emerged healthy and fertile.
Formerly, cloning an animal beyond two or three generations was fraught with difficulties. Often, animals cloned beyond three generations were born with abnormalities, or wouldn’t survive birth. Scientists pointed to faulty histones in cloned embryos as the cause of these abnormalities. Histones are proteins in cell nuclei that package sequences of DNA into nucleosomes, a structural unit of the building-block molecules.
“So far, nobody has been able to explain the reason for this,” Teruhiko Wakayama of the RIKEN Center told New Scientist. “We thought that this limitation was caused by the accumulation of genetic or epigenetic abnormalities.”
But Wakayama’s group of researchers found a chemical that can overcome this issue. After inserting a nucleus from a cell from the mouse to be cloned into another mouse’s egg cell, the resulting hybrid cell is then bathed in trichostatin, an enzyme blocker. Trichostatin more faithfully resets the cell nucleus to an embryonic state, tricking the nucleus into acting like an embryonic cell.
“This is very impressive work. If this translates to other mammalian species - including humans - it could be a major game changer,” said Robert Lanza, chief medical officer at Advanced Cell Technology, a Massachusetts company that develops treatments using stem cells.
Cloning is a complicated game, and Wakayama is sticking to what he knows: “I am a mouse researcher and have no experience with other species. I will not even attempt to use rats, because male rats are extremely difficult to clone.”
This has applications beyond just scientific research. Cloning multiple generations from a single individual would be great for encouraging certain traits.
“If a ‘super cow’ that could produce a lot of milk or Kobe beef could be cloned at low cost, then not only consumers but also farmers would be happy,” said Wakayama.
The researchers are also looking into cloning mice from other, less desirable sources. Wakayama’s team is now planning to an attempt to clone individuals from stuffed bodies, excrement and mouse fur. If it succeeds in mice, this could be a possible method for cloning extinct animals from preserved remains or museum specimens.

Researchers say that exercising makes you lazy and that it doesn't lead to weight loss as we initially believed. The study was conducted to find out why exercise seems ineffective to most Americans.
In Theory: Weird Creatures Inhabited Earth Billions Of Years Before Dinosaurs
Life on Earth was thought have been created approximately 800 million years ago, but a shocking new discovery that there is an advanced animal-like creatures might have wonder the planet 2.3 billion years ago, before they died out because of lack of oxygen.
IVF Treatment: World's First Three-Parent Baby Born To Infertile Woman
Initial tests show that the baby is "completely healthy." The 34-year-old infertile Ukrainian woman has previously undergone four IVF cycles previously, but all of them had been unsuccessful.
Techno Music Effect: Repetitive Bass Line Could Help Test Tube Babies Grow
Techno music made eggs more likely to grow into embryos and much more likely to develop to the stage in which they could be implanted. Experts say that techno music's repetitive bass line increased the number of viable embryos by around five percent.

Netflix is Raising Prices, Here’s How it Now Compares to Other Streaming Services
Once a brand gains the trust and loyalty of its market, it is only logical that it attempts to flex its dominant muscle. Such is the tale that fits the recent price hike coming from the stable of Netflix. Having baited consumers into believing that streaming, and not cable subscription, is the right way to go, Netflix has now decided to drop its own form of a bombshell on consumers in the form of price increment. The news, which was announced earlier this year, detailed that Netflix would be raising prices across all of its plans by 13 to 18 percent.
